[TOOL] U9508 Bootloader Unlock – B707 Fastboot V3

ToolV3

A small tool to easily unlock U9508 Bootloader and flash any custom kernel/recovery!

The U9508 official B707 system update by Huawei includes an updated “fastboot” partition.

After flashing this partition, the phone will automatically unlock its bootloader, once and if an unsigned kernel or recovery is installed.

 

Unlocking the bootloader MAY void warranty.

I am NOT responsible for any damage you made to your device.



How to use this tool:


    

  • Make sure you have adb drivers installed before using this tool. If you don’t, just install HiSuite. Also, enable usb debugging in developer options.
    • 

  • Connect the device to your pc via usb and run the tool.
    • 

  • Select option 1 (so insert 1 and press enter) to install the new fastboot partition, which is able to unlock your device if you install an unsigned kernel / recovery.
    • 

  • Select option 2 if you haven’t enabled usb debugging, or if you have previously flashed an unsigned partition and now your device isn’t booting.
    • 

  • Select option 3 to flash a custom kernel you have previously renamed to boot.img and put on your desktop. Do NOT use dd dumps, so do NOT use boot.img you can find in flashable rom zips.
    • 

  • Select option 4 to flash a custom recovery you have previously renamed to recovery.img and put on your desktop. Do NOT use dd dumps neither here.
    • 

  • Select option 5 to check if bootloader is locked, unlocked or relocked.
    • 



DO NOT use dd dumps with this tool, so do NOT use boot.img you can find in flashable rom zips.


DO NOT flash any unsigned kernel or recovery before flashing the B707 fastboot partition (opt 1 or 2 in this tool), or your phone won’t boot.


 


HOW TO “RELOCK” BOOTLOADER


After your bootloader status is “unlocked”, if you want to flash a stock rom with dload method , you need to flash chinese recovery (not another one), then flash any of my roms (or any other rom with both boot.img and reserved.img), let the device boot at least once, and the bootloader will be “relocked”; then you can install the original recovery and use the dload method again.
