  • Huawei Mate 9 MHA-AL00 Bricked


    I have Huawei Mate 9 MHA-AL0 that is not turning on. It is seen in device manager as Huawei COM1 and Android Single ADB interface. adb is not showing my device.

    HCU tool is able to read device info (only serial number and model) :

    Before detection connect cable to usb and enable Manufacture mode !

    Since device is not turning on, I am not able to put it in Manufacturer mode

    When I try to write down IMEI or unlock bootloader I am getting:

    Unlock Bootloader

    2020-01-06 02:07:27.610 Autodetect COM port and phone type start!
    2020-01-06 02:07:27.626 Compatible COM ports not found!

    Phone not found !

    In DC Phoenix, I am able to Update OEMINFO by selecting (bootloader+Update OEMINFO and unlock Huawei ID). This only works with Kirin_T2_A7.0_V4 bootloader. Its failing to read device on any other bootloader.
    For OEMINFO file i tried with bothe MHA-AL00 and MHA-L29.

    Tested all 3 methods
    Firmware files that I used are:

    HLMHAAL00AM00A074_Board_Software_general_7.0.0_r1_ EMUI5.0_05021YVS.dgtks

    Whatever firmware that I try, I am getting xloader errors:

      Hi Valdemaras,

      mi phone is showing Build number: :MHA-AL00C00B231 and I can't find firmware matching that. Can you please help out more specific and help. I tried following all steps and methods, but didn't get it to work.

      And initial build version was MHA-L29, which as i can see is not supported also.

      If my version is not supported, and you are not willing to help out, I would like to get my money refunded please.

      Thank you.
