How it works (in a nutshell)
Even before creating PotatoNV, @TishSerg discovered that unlock key can be rewritten with the SHA256 hash of the desired key to the USRKEY
property. However, to access NVME (a raw partition that stores stuff like serial number, device traits, etc.), a user should flash custom recovery or gain temporary root privileges. But both methods are complex and are not guaranteed to work. After researching the legacy bootloader of some Huawei devices, I've found a nve
command, which allows to read or write any property in the NVME partition. Of course, this command requires an unlocked bootloader.
So it remains to find a way to quickly unlock the bootloader. The way out is quite simple - use the bootloader from the board software.
The program uploads a special "USB bootloader" (exported from the board software) through the DOWNLOAD_VCOM
mode. VCOM is smth like EDL on Qualcomm devices: it can be triggered by a system failure or by shorting testpoint.
After uploading the bootloader, the device should switch to the fastboot mode. The "USB bootloader" has an important trait: it's unlocked out-of-the-box, so it allows to execute any command.
So, we're just going to send a command through the USB bulk interface to write SHA256 hash to USRKEY and reboot the device.
That's it.
