Firmware via clockworkmod recovery. How to install custom Recovery

What should you do if your Android smartphone suddenly starts to freeze and behave as if it wanted to live its own life? How to reflash Android? Many users ask this question modern gadgets various brands - from top-end “Samsung” and “Sony” to the Chinese “Xiaomi”, which is now gaining popularity (more often in colloquial speech- “Xiaomi”) and “Meizu”.

Possible solutions to problems

One of the most simple tips The device settings will be reset to factory settings. Indeed, in this case no third-party intervention is required - all settings and resets are made on program level. But this trick will only work if the smartphone’s malfunctions are caused only by software and clogged memory. After resetting the settings, and in frequent cases erasing the content, the device turns on like new.

What is "Recovery" and what is it eaten with?

Many immediately give up their positions and throw out the white flag, rushing to contact service centers. But any experienced user will tell you that this is not worth doing. After all, you can save yourself extra nerves and cash, just by following simple steps from this manual.

"Recovery" is software a smartphone based on the Android OS, which is something like a “BIOS” on a PC. That is, using “Recovery” you can completely reset your smartphone to factory settings, you can also install updates operating system and just flash it. When purchasing in a store, the user most often receives a device with a factory “Recovery” menu, which is slightly limited in functionality and will not allow you to successfully flash the operating system.

If we talk about “custom” (translated from English custom - “made to order”) “Recovery”, then it will allow you to more fully “communicate” with the phone system, make backup copies of firmware and restore them, as well as make a more complete and deep reset of the device.

How to enter "Recovery"

To flash your device via Recovery, you must first get into this very menu. This couldn’t be easier to do, especially since on many devices the input combination is exactly the same. So, if the smartphone has a physical central button or a Home button (most often found in older Samsung and LG devices, but it may also appear in more modern devices), you need to hold down the “Home” and “Volume +” buttons with the gadget turned off, and then, without releasing them, press the power button.

The device will turn on desired mode. If you have a more modern device without a physical Home button, you need to repeat the process described above, but using only the Volume + button and the Power button. If the desired result was not achieved, you should refer to the extended list of ways to enter the “Recovery” menu for different manufacturers.

What else will you need?

In order to understand how to reflash Android, you first need to download the firmware for your device. Most often, firmware files are hidden from public view for security purposes and to protect the manufacturer’s data. That is why ordinary users create backup copies of their operating systems and form databases of stock firmware from them, links to which can be found on specialized sites. It is the firmware file itself, located in the archive with the *.zip extension, that you will need to understand how to restore Android using Recovery.

There are also times when you are tired of the old stock firmware and want something new. That is why there are always craftsmen who create custom firmware, “cutting out” the unnecessary from them or, conversely, adding something new. In such cases, it will not be possible to use the standard “Recovery”, and here those same custom CWM Recovery (ClockWorkMod Recovery) or

Installation or TWRP

It is not necessary to install Recovery on Android via a computer; most often, on the contrary, it is easier to use the stock one. All you need to do is download the necessary file, again located in an archive with the *.zip extension, and place it on the external flash card of your smartphone.

After that, going to the stock “Recovery”, you need to select the “Apply update from external storage” item and in the list that opens, select the same file with the custom “Recovery”. After confirming your choice, the installation process will begin, after which the device will prompt you to reboot. The process is complete.

How to flash Android via Recovery

Moving directly to the process of installing the firmware itself, I would like to say that all unofficial files of the Android operating system, created directly by users of certain devices, should be installed at your own peril and risk. If, however, the decision is made to install a non-native version of the software, you should make sure that the firmware is “written” specifically for the phone that you plan to reflash.

If we are talking about stock firmware, then don't bother installing CWM Recovery or TWRP. All manipulations that need to be done are limited to downloading the factory firmware file and placing it on an external memory card. After this, the process is similar to installing a custom Recovery. That is, you need to go to the stock “Recovery” menu, select “Apply update from external storage”, then specify the firmware file directly and confirm the action. After the process is completed, you need to take one more step that will help avoid freezes and glitches when turning on and operating the device. Immediately after the firmware is completed, you need to select the “Wipe data/factory reset” menu item and confirm the action. This will clear information about previous software and files that were present on the device before the firmware process.

After completing these steps, you must select the menu item “Re boot system now". The device will reboot and the process of setting up the smartphone from scratch will begin. If the switching process takes a long time and the device logo “hangs”, it’s worth remembering whether the settings reset item was performed after flashing.

Custom versions of Android

How to flash Android via Recovery is, in principle, clear. It remains to figure out what to do with OS versions written directly by device users. The answer is simple: the process needs to be repeated, performing the same manipulations in custom “Recovery”. The only difference is that the firmware file itself can now be placed not only on an external memory card, but also on internal memory devices. This adds convenience in the event that a flash card is simply missing. In this case, you will have to select the “Apply update from internal storage” item.

It is also worth noting that in CWM Recovery and TWRP the “Wipe data/factory reset” item has been replaced with two separate items: “Wipe data” and “Wipe cache”. After installing “Android” through “Recovery” (namely, the custom version) has succeeded, in the modified ClockWorkMod or TeamWin menu you need to select the “Wipe Dalvik cache” sub-item, which will significantly increase the chances of successfully turning on the device with the new operating system.

Restoring stock firmware

If you don’t like it or don’t get used to it, there is always the opportunity to return everything to its place. Many people ask the question: “How to restore Android through Recovery, namely the stock version?” The answer lies in the point above. Roughly speaking, returning everything to normal occurs in the same way as making the initial changes.

All you need to do is download the firmware from the manufacturer to a flash card or internal memory, then select the appropriate “Recovery” menu item and do a complete reset of settings/content. In principle, nothing complicated.

It seems that understanding how to flash Android via Recovery is not so difficult. But if some points are unclear, or you are not confident in your knowledge, it is better not to get involved with such processes. But even if something doesn’t work out, you can always restore the device’s firmware through the corresponding menu item. The main thing is, before flashing Android via Recovery, do backup copy. To do this, you will need a custom “Recovery” and a little patience, because the process of backing up the firmware takes a lot of time.

If something goes wrong, you can always contact knowledgeable people. By at least in an authorized service center will definitely help. The main thing is not to lose heart and move forward confidently. This is the only way to achieve any results. Good luck with the flashing!

For old CWM

Everyone good day today we will talk about alternative recovery for your Android device. Everyone knows that every smartphone has its own recovery, but it is very limited in functionality (installing updates and resetting settings). And we’ll look at ClockworkMod Recovery (an alternative recovery), start with a strict understanding of why it’s needed, and end with instructions for flashing the smartphone’s firmware.

Alternative recovery ClockworkMod

ClockworkMod Recovery- this is a much more powerful, compared to the factory, system recovery utility (menu), which allows you to make full backup copies of the entire system of the device, install software, firmware, kernels and much more on it, which usually does not allow you to do factory recovery. ClockworkMod, installed in a special system partition internal memory of the tablet or phone, in place of the factory recovery menu. Closest competitor ClockworkMod Recoveryis TWRP Recovery.

ClockworkMod Recovery can help you out with some seemingly hopeless situations. Even if your tablet or phone cannot boot, in many cases with using CWM you can restore the system with all its settings and applications. Download ClockworkMod Recovery is available on the website 4pda.ru for your specific phone model.

Here is a rough list of what you can do with ClockworkMod Recovery:

• Install custom firmware and unofficial kernels
• Install factory system updates, add-ons and patches
• Connect to a computer via USB in removable storage mode
• Connect to a computer via USB to work with the ADB program
• Create a complete backup copy of the current firmware and its individual parts (system, settings, applications)
• Restore a device from a previously created backup
• Reset to factory settings (Wipe – data/factory reset), clear cache (wipe cache), clear Dalvik-cache (wipe Dalvik-cache), clear battery statistics (wipe battery stats)
• Create partitions on a memory card and format themClockworkMod Recovery was created by developer Koushik Dutta (also known as Koush) and there are CWM versions for most Android phones and tablets.

Installing ClockworkMod Recovery

For many smartphones and some tablets, installing ClockworkMod Recovery is very simple procedure, you just need to install the program from the Market ROM Manager and the first item in its menu will be the ClockworkMod installation item. For other devices there may be separate utilities, similar to the application Acer RecoveryInstaller for tablet Acer Iconia Tab, or ClockworkMod Recovery is installed on them using the adb program.

Launching ClockworkMod Recovery

There are several ways to boot your tablet or phone into ClockworkMod Recovery.

1. Using the ROM Manager program, selecting the “Download” item in its menu Recovery mode».

2. By pressing a specific key combination when turning on the device. This combination depends on the device model. On many devices, you can get into recovery by pressing the volume down and power buttons at the same time when turning them on.

3. By using ADB programs. If you have set up a connection to your computer using the ADB program, you can boot your tablet into recovery using the command:

adb reboot recovery

Purpose of menu items ClockworkMod RecoveryAfter loading your tablet into ClockworkMod Recovery, you will first see its main menu: On most devices, you can usually navigate through menu items using the volume buttons. Use the power button to select desired itemmenu. Some devices may also use other buttons, for example to return to the previous menu.

Purpose of main menu items:

2 .apply update.zip from sdcard - This is one of the most frequently used items in ClockworkMod Recovery.

With its help, you can install both official and unofficial (custom) firmware, install kernels, themes and other software, which should be located in the update.zip file, which you should place in the root of the memory card (in file manager Android device is the /sdcard folder).
After selecting this item, you will be taken to the next menu, where you must confirm your choice by going to Yes – Install /sdcard/update.zip

3. wipe data/factory reset - Complete reset of settings, data and cache. After this, your phone or tablet will return to the condition in which it was sold in the store. ClockworkMod will clear the /data and /cache partitions in the device's internal memory. Everything from the system folder ".android_secure" on the memory card and the sd-ext partition will also be deleted.

4. wipe cache partition - Cleaning the /cache partition in the internal memory. All temporary data that the system and programs have accumulated will be cleared. This item is usually used before installing new firmware or kernel.

5. install zip from sdcard - installation zip file from the memory card. After selecting this item you will be taken to the following submenu:

• apply /sdcard/update.zip - this item is completely similar to item 2 of the main menu “apply update.zip from sdcard”
• chooze zip from sdcard - select the .zip file on the memory card to install.

This point is also similar to point 2 and is also used to install firmware, kernels and other mods. Its only difference is that installation can be done from any zip file with any name, located anywhere on the memory card. After you select this item, a list of files and folders on your memory card will open, from which you need to select a .zip file to install.

• toggle signature verification - on/off file signature verification.

If you enable Signature check: Enabled, you will not be able to install alternative firmware that has not been signed by the developer. Developers do not sign most custom firmware.

• toggle script assert - on/off approval script.

This item is for internal use in CWM and you'll never need it, so it's best to leave it alone.

• +++++Go Back+++++ - this item, as already mentioned, is used to return to the previous ClockworkMod menu

6. backup and restore - creating and restoring backups. Another one of the most important points of ClockworkMod. With it you can do full copy the entire tablet system, along with the data and applications available in its internal memory - the so-called Nandroid backup, or a snapshot of the system, and then, if necessary, return the tablet to this state. This menu looks like this:

Its points mean the following:

• Backup - creating a backup copy of all partitions in the internal memory of the device.

The backup copy will be saved on the memory card. By default, the name of the backup contains the time and date it was created. You can rename the backup. The title must consist of Latin letters and numbers and do not contain spaces

• Restore - Restore all partitions from the selected backup.

By selecting this item, you will see a list of backup copies available on the memory card and you can select from it the copy you need to restore.

• Advanced Restore - restoring a specific partition from a selected backup.

You can select a separate partition that you want to restore from a backup - boot, system, data, cache or sd-ext partition as shown in the screenshot:

7. mounts and storage - mounting individual partitions, formatting them and mounting the device in as USB drive when connected to a computer (mounting makes partitions or folders available for use).

The items in this menu mean the following:

• mount/system- mounting the system partition
• unmount/data - unmounting the data partition
• unmount/cache - unmounting the cache partition
• mount/sdcard - mounting a memory card
• mount/sd-ext - mounting the Linux ext partition on the memory card (if there is one)
• format boot format system, format data, format cache - formatting the relevant sections.

Attention! Be careful with these menu items. For example, formatting the system partition will destroy your operating system (current firmware). After formatting the boot partition, you will not be able to boot your device and it will turn into a brick.

• format sdcard- formatting a memory card
• format sd-ext - formatting a Linux partition on a memory card
• mount USB storage - connecting a tablet or phone to a computer in removable storage mode

8. advanced - additional functions of ClockworkMod.

This menu consists of the following items:

• Wipe Dalvik Cache - clearing the cache of the Dalvik Java virtual machine, which is used to run applications. This menu item is usually used before installing new firmware, especially unofficial ones.
• Wipe Battery Stat - Resetting battery statistics. It is believed that this item should be used when the system battery level indicator shows incorrect values. However, Google, the developer of the Android system, claims that this should not affect the correctness of the indicator readings.
• Report Error- report a bug. You can report the ClockworkMod recovery bug to its developer. The error log will be written to the memory card, and you can send it to the developer using the ROM Manager program.
• Key Test - checking the functionality of the device buttons, when you press a button, it displays its code
• Restart adb - reboot ADB server. This item helps when the device has stopped responding to commands from the ADB program when it is connected via a USB cable
• Partition SD Card - creating partitions on a memory card. This item is used to create /sd-ext and /swap partitions on the memory card. The /sd-ext partition can be used by some firmware when there is not enough internal memory on the device, for example, to expand the /data partition. /swap partition is usually used for speedup Android work devices.
• Fix Permissions - Correct access rights to files and partitions. This item is used to return access rights to system files and folders that may be changed due to the incorrect operation of some root applications, which can lead to freezes and malfunctions of the tablet or phone.

Backup and restore your device using ClockworkMod

As you already know, using ClockworkMod you can create a complete backup of the firmware of your tablet or phone (Nandroid). CWM takes pictures of all partitions in the internal memory of the device and the “.androidsecure” folder located on the device’s memory card. A snapshot is taken not only of the operating system, with all its settings, but also of installed applications.

Making a backup copy (Nandroid Backup):

• Open the item "backup & restore"
• Select "backup"
• Confirm your choice by going to "Yes"

A file with a full backup copy will appear on your memory card, located in the clockworkmod/backup folder. The file name consists of the date and time the copy was created, but you can rename it. Do not use Russian characters or spaces in the file name.

Restoring a device from a backup using ClockworkMod:

• Reboot the device into CWM recovery
• Open the item "Backup & restore"
• Select "restore"
• Select the desired backup copy from the list.

Note: Selected applications from ClockworkMod Recovery backup, SMS and WiFi settings without touching the current firmware, you can restore it using the application AppExtractor. The program can also extract applications from a backup copy Titanium Backup.

Installing firmware, updates, kernels and more on an Android device using ClockworkMod

• All alternative firmware, custom kernels, cracks, add-ons, decorations, application packages that can be installed on a tablet or phone using ClockWorkMod recovery are packaged as a zip file.
• Before installing anything on your device, do not forget to make a complete backup copy of the current firmware, so that later you can painlessly return your tablet or phone to its original state.
• Make sure your device's battery is fully charged and disconnect it from your computer and charger.
• Copy the file you want to flash to the memory card, preferably to its root, WITHOUT UNPACKING IT. Make sure that the file name consists only of Latin letters and numbers and does not contain spaces or special characters.
• If you are installing new firmware, be sure to do complete cleaning using the item "wipe data/factory reset"

Let's start with the firmware:

• Insert the memory card into the device
• Reboot the device into ClockWorkMod recovery
• Select "install zip from sdcard".
• Open the item “choose zip from sdcard”.
• In the window that opens, we find our file, it will be located at the bottom, after the list of folders (if they are on the memory card)
• Confirm your choice by going to “Yes”.
• After finishing the firmware, return to the previous menu using the item “++++++Go Back++++++”
• After flashing any zip files It is highly recommended to clear the cache and dalvik cache.

Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are extremely popular. This OS was developed by Google, and now its market share is incredibly high. iOS from Apple and Windows Phone an insignificant percentage of presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system crashes - distinguishing feature any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that it is possible to do without such radical measures. After all, every Android gadget has Android. System Recovery 3e. How to use it and what is it even? This is what we will talk about.

What kind of animal is this?

What does it mean Android System Recovery 3e? This is a kind of BIOS mobile device. Any operating system has its own BIOS - basic system I/O that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It serves to restore the functionality of a smartphone or tablet, apply critical updates or do a factory reset. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English language. Therefore, many people do not even know how to use recovery correctly.

That is why this article was written. Android System Recovery, the instructions for which are absolutely necessary, is powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to waste money on specialists. Doing everything yourself is much easier and cheaper. We will analyze each item in the recovery menu and tell you everything we can about it. So let's begin.

How to enter recovery?

It depends on the specific model devices. In some devices you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Old models with mechanical button"Home" requires pressing this button as well. Some devices require pressing simultaneously power and volume buttons. There are also those who must hold down the power key and both volume buttons. This applies only to original devices from well-known manufacturers.

But there are also frankly “Chinese” gadgets with an incomprehensible operating system and “crooked” translation. Standard Methods Logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the key combination you are looking for. But this option is not suitable for everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. The second option: find the desired combination by pressing all the buttons one by one. Now let's move on to the Android System Recovery 3e menu items.

Reboot system now

This menu item does full reboot devices. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this into account.

The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of a reboot: to allow the device to apply all the changes made. True, after some of them the smartphone may not boot at all. But that's a completely different story.

Apply Update from External Storage

This menu item allows you to apply the update that is located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this you need to go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.

This paragraph has other subparagraphs that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, it immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required for them. If there are errors, then put this firmware no need. That's the whole story.

Wipe Data. Factory Reset

This is a very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in the firmware. And this option allows you to perform this operation.

This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly says what to use Wipe Data & Factory Reset It is necessary before each device firmware update.

Wipe Cache Partition

Another one useful command in Android System Recovery 3e. The recovery instructions say that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, then this one clears its cache. Namely, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for clearing the Android OS cache. And they work great.

It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even “cleaner,” which will have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.

Wipe Battery Stats

This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, in which the Current state battery, its nominal capacity and other necessary parameters. Resetting usage statistics battery, it will be possible to extend her life a little. Yes and new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory smartphone. This item allows you to clear a memory card or built-in memory, format it, or attach it as a drive directly from recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot your smartphone into the operating system. In order to mount the device’s memory card as a drive, you need to select Mount USB Storage. Once the connection is established, the computer itself will establish necessary drivers for work.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy necessary files and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.

Recovery errors

Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of the firmware or package. It can occur for several reasons: the firmware file is damaged, incorrect information in binary file or the firmware simply does not suit this device. But there is another option: before flashing the firmware, the device was not reset to factory settings. It’s good that they can be easily fixed in the same recovery. There are several ways to do this.

So, if the error occurs due to broken file firmware, you should download it, connect your smartphone to your computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. And here Android error System Recovery 3e "No command" is very rare. It only appears when the user tries to install an update via ADB. Usually this method doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.

Conclusion

So, let's summarize. We tried to describe the capabilities of Android System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.

Everyone has it smart device, be it Windows, Android, iOS or others, there is a special mode that is activated without using the main operating system. And if on Windows it is Bios and partially " Safe mode", then all Linux systems, which also include Android and mobile Apple devices, there is a special “Recovery Mode” or simply Recovery (recovery). Using this mode, you can install operating system updates and perform a factory reset. To enter recovery it is usually used special combination keys, as standard, are Power + Vol-/Vol+, which are pressed when the smartphone is turned off.

For users who want to make the most of their device's resources, the pre-installed Recovery is not enough. Modifications and redesigned recovery modes have been developed especially for them, which completely open access to the smartphone’s file system, resulting in the following possibilities:

• complete reinstallation of firmware
• installations individual elements firmware;
• flexible system cleaning;
• creation ;
• restore from Backup;
• creating or formatting partitions in flash memory;
• connection to PC via USB ADB mode or "flash drives"

This is only a small part of what the modified recovery is capable of.
Despite the significant expansion of the basic functionality of the recovery mode, installation requires certain knowledge and skills.

Incorrect actions or omission important details may cause the device to malfunction. Please also be aware that the instructions below are intended to serve only as a guide. general leadership, A necessary files and drivers must be selected for a specific device, for a specific version of Android and processor architecture.

Installation methods for Custom Recovery

ROM Manager

The simplest method that does not require much experience in non-standard work with the device. The only thing that is necessary is, which will not be difficult to obtain if you follow our guide.

The essence of the method is to install special application- . Next, do everything strictly with step-by-step instructions:

You can check the success of the operation by returning to the main menu of the utility and clicking " Boot into Recovery mode". If everything went well, then the newly installed modified recovery mode will start. If it fails, the phone simply won’t turn on and you will have to restore it using the FastBoot mode, but this is in most cases, but if you’re really unlucky, then go to a service center or secured for a new phone.

TWRP rom manager

Almost the same as ROM Manager with the only difference that a recovery modification from another developer will be installed - .
The application has a narrow functionality, which consists in identifying the device and downloading the desired one. installation file followed by installation. Understanding the utility will not be difficult even for a beginner.

In addition, there is a useful function for creating in just a few clicks. True, this opportunity will appear only after installing TeamWin Recovery Project.

Firmware Custom Recovery via FastBoot
