Huawei Bootloader Tools

This repository contains a set of scripts that can help you (un)lock the bootloader.

Success rate

The success rate depends on the region where you bought the device. You will have most luck with devices bought in Europe, as they only contain numbers in their bootloader unlock code. You can try with other regions as well, but you have way smaller chance of succeeding.

Tested devices

Devices which have been tested with the original Python script:

(see: SkyEmie/huawei-honor-unlock-bootloader#summary)

• Honor 5x, 8x, 9x
• Honor view 10 and 20
• Honor 10 lite
• Huawei P20 lite
• Huawei Y6 2019
• Huawei P30

⚠️ For users who came to bruteforce ⚠️

There may be other (easier/faster) ways to acquire your device's code.

PotatoNV

https://github.com/mashed-potatoes/PotatoNV

If your device has a Kirin CPU and you are okay with disassembling the device (usually it's just removing the back of the device and maybe taking off a motherboard shield), you should try PotatoNV first!

PotatoNV utilizes what is called the "software testpoint". By shorting it out you boot into a "testpoint" mode which can perform actions like rewriting the unlock code, which is what PotatoNV does.

It took me around 10 minutes (maybe less) to get the unlock code on my P20 lite (granted, it may take bit longer as my device was opened previously).

Requirements

• EMUI 9 or lower

  Unfortunetely, with EMUI 10 and later the oem unlock command required for bootloader unlocking has been removed by Huawei, meaning that there is no way for consumers to unlock their device, regardless of whether they do have the code or not.

• USB Cable

  To connect the device to your computer

• Internet connection (optional)

  The latest platform tools (containing fastboot and adb required by this script) are downloaded using the download-platform-tools.mjs script which required internet connection. To manually include these scripts, put the binaries into {directory_with_scripts}/bin/{distro - win32/linux/darwin}/platform-tools/

• Node.js 14 or later (older are not tested)

  These scripts are written in JavaScript which require Node.js to run. You can download it here: https://nodejs.org/en/

OS Support

The scripts are written to support all operating systems, however if the device is not detected, additional drivers may be necessary.

Configuration

Before running any (un)locking scripts, you must create a config.json file and fill it out. Do so by renaming config.example.json to config.json and fill out everything to your needs.

imei (number) - IMEI of your device. You may find it in your device's settings or on your phone's box.

autorebootAfter (number) - How many attempts until the device will be automatically restarted. Most Huawei/Honor devices also have a protection which restarts the phone after few attempts. This would significantly slow down the process and would require your intervention. It's recommended to try without this option (remove this field from the config) and see if such behavior occurs. If so, set it to 1 less than the amount of attempts that trigger the restart (eg. restart after 5 seconds - set to 4 - this is the most usual).

saveStateAfter (number) - How many attempts until the current state (last attempted number) is saved. In case the script gets interrupted, it can recover from the last saved state. Do not set this number too lower to prevent damaging/wearing out your computer's drive.

throwOnUnknownErrors (boolean) - If an unexpected output from adb/fastboot is received, should the script throw an error (= end)? Usually, this is set to false, but in some cases it might be usefull.

Recommended configuration

{
  "imei": xxxxxxxxxxxxxxx,
  "autorebootAfter": 4,
  "throwOnUnknownErrors": false,
  "saveStateAfter": 200
}

Before running the scripts

Before running the scripts for the first time, make sure to read through these steps:

Installing dependencies

You need to install all dependencies by the scripts so everything works as intended (or at all).

You can do that by running this command (Node.js is required):

$ npm install

Downloading Platform tools

For using the (un)lock scripts, you must run the download-platform-tools.mjs script first.

$ node ./scripts/download-platform-tools.mjs

Alternatively, if you're not connected to the internet but have platform tools downloaded, you may place them here: {directory_with_scripts}/bin/{distro - win32/linux/darwin}/platform-tools/

Setting platform tools as executable (Linux/macOS)

You will only need adb and fastboot:

chmod +x bin/{distro - win32/linux/darwin}/platform-tools/adb
chmod +x bin/{distro - win32/linux/darwin}/platform-tools/fastboot

Enabling USB debugging

First, you need to go to Settings > Developer options (not enable by default, to enable, go to About phone and tap the Build number field 7 times, then go back and it should appear) and enable USB Debugging and OEM unlocking. Then, connect your device to the computer (if it's not already) and it will ask you to allow usb/adb debugging. Allow it and make sure to check Always allow from this computer.

Running the scripts

Please make sure that the device is connected already. It doesn't matter whether if it's in fastboot/bootloader mode or not.

Bruteforce bootloader

You can run this script by using this command:

$ node scripts/bruteforce-bootloader.mjs

It takes a lot of time as the script attempts to bruteforce the code (= attempts lots of combinations). This will take hours days, depends purely on your luck.

Warning: When the correct code is found, the phone is instantly unlocked, which means that all your data will be ERASED. Sometimes the device may prompt you before unlocking the phone, however make sure to back up your data regardless.

Lock bootloader

You can run this script by using this command:

$ node scripts/lock-bootloader.mjs <oem_code>

This takes usually just few seconds. After that, your device will reboot.

Unlock bootloader

You can run this script by using this command:

$ node scripts/unlock-bootloader.mjs <oem_code>

This takes usually just few seconds. After that, your device will reboot.

Download Platform tools

You can run this script by using this command:

$ node scripts/download-platform-tools.mjs

The platform tools are downloaded into the bin/{os}/platform-tools folder.
