Unlock tool for Huawei devices on Kirin SoC. This project is not affiliated with Huawei. It would be much appreciated if you want to make a small donation to support my work!Īll bootloaders are Huawei Technologies Co., Ltd. So, we're just going to send a command through the USB bulk interface to write SHA256 hash to USRKEY and reboot the device. The "USB bootloader" has an important trait: it's unlocked out-of-the-box, so it allows to execute any command. VCOM is smth like EDL on Qualcomm devices: it can be triggered by a system failure or by shorting testpoint.Īfter uploading the bootloader, the device should switch to the fastboot mode. The program uploads a special "USB bootloader" (exported from the board software) through the DOWNLOAD_VCOM mode. The way out is quite simple - use the bootloader from the board software. So it remains to find a way to quickly unlock the bootloader. Of course, this command requires an unlocked bootloader. 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. But both methods are complex and are not guaranteed to work.

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. How it works (in a nutshell)Įven before creating PotatoNV, discovered that unlock key can be rewritten with the SHA256 hash of the desired key to the USRKEY property. Get binaries for Windows in the releases section.įor Linux or macOS consider using the PotatoNV-crossplatform.
