One day one of our website visitors asked for help. He needed to flash a Lenovo S820, and he didn’t quite figure out how to do it correctly and not get bricked. So I decided to write detailed instructions on how to properly flash a Lenovo S820 idea phone.

What you need to know

Firmware for Lenovo S820 comes in two types: custom (firmware modified by advanced users) and official, in turn, the official version is divided into Chinese multilingual and European. Links to download official firmware can be found at the end of the article, and custom versions can be found on the Internet, for example on NeedRom.

When choosing firmware, be careful; Lenovo S820 is available in two variations: 4Gb RAM and 8Gb RAM, and accordingly they come with different firmware.

You can flash a smartphone in several ways: using a computer or through recovery mode. If you use a computer, then you will need the SP Flash Tool. You can read how to use it in, also in this article you will find how to correctly install gadget drivers. Firmware for SP FLASH TOOL is packaged in an archive with a *.rar extension and if you unpack it you will see many files. In this archive, you need to make sure that there is a scatter file “MT6589_Android_scatter_emmc”, see Figure 1 below.

As for the recovery mode, there are ROM firmware for under and under TWRP Recovery. CWM and TWRP Recovery are small programs (something like the BIOS on a computer) that allow you to flash your Lenovo S820, update it, install various patches, and even install applications or games. As a rule, when you find a firmware for yourself, the developers indicate what to flash: CWM Recovery or TWRP Recovery. Such firmware is also archived and has a *.zip extension.

Preparing the phone for firmware

So, you have a smartphone, a computer and a data cable and you need to flash the Lenovo S820. To do this, first charge the gadget, then download drivers for MTK devices (for a switched off body), and the program. After this, you need to decide on the choice of firmware (official or custom) and download it. Now you have everything to start the process of flashing your phone. But before flashing it is highly recommended.

Sewing process using SP Flash Tool

After you have made a backup of your firmware, you can start flashing it. Now turn off your phone, launch the SP Flash Tool program and specify the path to the scatter file by clicking the “Scatter-loading” button, see fig. 2.

By specifying the path to the file, blocks that will be flashed will appear in the lower field. You need to make sure that all the blocks have a check mark, and “Preloader” too. Next, check the “DA DL All With Check Sum” checkbox and press the “Firmware->Upgrade” button, see fig. 3.

The Flash Tool will begin to create a firmware image (pink progress bars will run at the bottom), while turning off the phone (if it is connected to the computer, then disconnect it), remove the battery and connect the phone to the computer while it is off. If everything is done correctly, the firmware process will begin (first a red and then a yellow progress bar will run at the bottom). If for some reason the progress line stands still and does not move, then try disconnecting the gadget from the PC, reconnecting the battery, and connecting it to the computer again. It didn’t help - then the problem is with the drivers, you’ll have to reinstall them (naturally, the firmware process needs to be interrupted). After the firmware process is completed, a window with a green circle will appear, see Fig. 4.

Congratulations, you have managed to flash Lenovo S820. Now you can disconnect your smartphone from your PC and turn it on. The first download is long, about 5 – 10 minutes.

Good luck! If you need any help, write.

We are not responsible for any damage caused to your phone if something goes wrong.

1. So, first you need to install the original Chinese firmware with pre-installed recovery according to these instructions:

The author of the idea is dear javum.
So we need FIRST OF ALL make a full backup: instructions.
Next we need a preloader from the P780 phone: preloader.7z 51K 857 downloads
Download the Chinese CN firmware (any), I personally took this one: S820_S139_130723
Next on the list:

    Let's unpack everything.

  • We take the preloader.bin file from the archive and throw it into the folder with the firmware.
  • Next, in the Flash Tool, select the scatter file that comes with the firmware.

    • Before starting the firmware click on PRELOADER and select the file from the archive that you put in the folder with the firmware.

    After flashing the firmware, again via FT, install TWRP 2.6.3

(With other firmware with CN markings that are sewn via FT, you need to do the same manipulations)

In order not to do the above mentioned manipulations, I post

ready-made CN firmware for Lenovo S820 8Gb
with built-in recovery TWRP 2.6.3 (install as standard via Flash Tool) : DOWNLOAD

That's it, you've got a device on which you can install absolutely any firmware from 4gb without patches, fixes, etc.
Personally tested: installed VIBE UI 1.5 and everything works great.

I don’t think it’s worth reminding that you do all these actions at your own peril and risk.

If you do everything correctly, then “scaling” will not happen!

2. If you don’t know what Flash Tool is and how to use it, then here you go:

For MT6513/6573/6515/6575/6517/6577/6589/8389

Full instructions with pictures:


3. Personally, I flashed the Flash Tool version SP_Flash_Tool_v3.1316.0.150, besides, by a turned off smartphone I mean turned off and with the battery removed, I flash it this way for the second time and it’s more reliable.

How to enter recovery:

  • With the phone turned off, press the power button and hold it for 1-2 seconds, then press the volume rocker “+” and “-” at the same time and release the power button, hold the rocker until you enter recovery. If it doesn’t work, then you need to practice... The whole point is to press the rocker until the lenovo inscription appears, and release the power button after it appears...
  • Using the utility Mobileuncle Tools(available in the market) select item Into Recovery Mode.

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

All alternative firmware, custom kernels, cracks, add-ons, decorations, application packages that can be installed on a tablet or phone using TWRP recovery are packaged as zip files.

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 at least 60 percent charged, preferably fully charged, and disconnect it from your computer and charger.

Copy the file you want to flash to the device memory or to a 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 a full wipe using the “Wipe” item

Let's start with the firmware:

1. Reboot the device into TWRP recovery

2. Select “Install”

3. Choose:

Memory card: Use external SD

Internal memory: Use internal storage

4. Select zip file

5. Using the option Force MD5 check on all Zips enable MD5 checksum verification if you have an md5 file included with your zip file.

6. We start the firmware by confirming the choice using the slider

You can also select up to 10 zip files to install at a time using the "Add More Zips" button, or clear the list of previously selected files using the "Clear Zip Queue"

6. By clicking Rebot and waiting about 5 minutes, I received a device with installed firmware from MIUI, Russified and beautiful.

Attention: if everything written for you is a dark forest, then do not even try to repeat it.

Update from 08/17/2015: LED indication DOES NOT WORK on the specified firmware. There are no more significant bugs. I highly recommend installing (via recovery) version MIUI 5.8.6. I'll post a video review of this firmware soon.

When a smartphone is brand new, it usually works as it should. However, over time, errors, freezes and bugs appear. Very often this is due to the firmware, updating which usually solves the problem. If your device was released recently, then software updates may arrive over the air. But what to do when the device is not the newest, for example, such as the S820 from Lenovo? Step-by-step instructions for flashing Lenovo S820 will help you with this.

First of all, the user needs to know that there are two types of firmware for this smartphone. The first ones are official ones, which were created by the manufacturer, and the second ones are called custom ones. The latter were created by other users and may contain various innovations that are not in the original. But it’s worth noting that these may have unexpected bugs and malfunctions. Therefore, you need to think carefully about installing custom firmware at your own peril and risk, or installing the official one and not having problems.

Before you download the firmware for Lenovo S820, you need to know that each smartphone model has its own software version. It is important to understand that if you install a shell that is designed for a device, for example, with a large amount of RAM, then there may be problems, including the destruction of the entire device.

There are several ways to install a new system. However, we will look at the simplest and most effective of them - flashing Lenovo S820 firmware via a computer using the SP Flash Tool program.

  • In the window that appears, click “ Install the driver from the specified location"and look for the path to the previously downloaded and unpacked driver;
  • We wait for installation and disconnect the phone.

Find out the version of the smartphone and download the necessary firmware

Another important thing before installation is to understand what version of the smartphone we have. The model was produced in different modifications in 2013 and 2014; you need to download the firmware according to the year of manufacture of the smartphone and its amount of RAM. This is necessary for the reinstallation of Android on the Lenovo S820 4Gb smartphone to be successful. You can find the necessary information on the box of your mobile device. After you understand what kind of phone you have, you can, in fact, download the official firmware for the Lenovo S820.
