Unlock Huawei bootloader with bruteforce

Summary

After closing the official EMUI website, which allowed you to retrieve the code to unlock the bootloader of Huawei/Honor phones, here is a python script to retrieve it by yourself.

It uses a bruteforce method, based on the Luhn algorithm and the IMEI identifier used by the manufacturer to generate the unlocking code.

The original version was developed by SkyEmi. I made some tweaks for saving failed attempts to file, because brutforcing is taking a looooooong time.

Instructions

Prerequisites

• Python > 3.7
• PyPI
• ADB
• Fastboot

Connecting a device in ADB mode

1. Enable developer options in Android at your phone.

   • Go to Settings > System > About device > tap Build number seven times to enable developer options.

2. Enable USB debugging and OEM unlock in Android.

   • Go to Settings > System > Developer options.

3. Connect your device to the computer

4. Replace IMEI_OF_YOUR_DEVICE by the first IMEI of your phone in this script:

https://github.com/titulebolide/huawei-oem-bruteforce.git
cd huawei-oem-bruteforce
python3 -m pip install -r requirements.txt
python3 unlock.py IMEI_OF_YOUR_DEVICE

5. Some devices have a bruteforce protection, preventing trying more than five codes. In this case, you will have to invoke the script with the option attempt-limit:

python3 unlock.py --attempt-limit 5 IMEI_OF_YOUR_DEVICE

6. If you want to pause the process you can simply exit the script by pressing CTRL+C. Write down the last shown "Attempt no.".

   • To resume invoke the script like so: python3 --resume-count ATTEMPT_NO IMEI_OF_YOUR_DEVICE
   • If you were using an attempt-limit use: python3 --resume-count ATTEMPT_NO --attempt-limit 5 IMEI_OF_YOUR_DEVICE

7. Make a few cups of coffee or tea => sleep => repeat :D

FAQ & Troubleshooting

If adb and fastboot are not found, you can try manually setting their path with the flags --adb and --fastboot. All in all, the python3 unlock.py --help manual can always be resourceful.
