Issue with Huawei mediapad m3

[laloire]

Hi
I use DC unlock to unlock the boot loader of my Huawei mediapad m3 (wifi only)

It said it worked

2025-02-16 15:01:12.357 Unlocking bootloader...
2025-02-16 15:01:12.364 Read from server...
2025-02-16 15:01:12.874 Read from server success!
2025-02-16 15:01:12.881 Unlocking bootloader...
2025-02-16 15:01:13.482 Unlocking bootloader success!
2025-02-16 15:01:13.937 Unlock bootloader success!
and when I reboot using `adb reboot bootloader` it does say phone unlock / FRP unlock.

However, when I try to flash twrp it fails (remote: 'image verification error')

I found on the web that it happens if the unlock didn't take / wasn't proper.
They suggest to relock and then unlock with the lock code.

Any help? I'm out of credit since I had 4 and they went with the unlock operation, the log doesn't contain the code it used.

What should i do?
Thanks

You should read the bootloader unlock code from your device by pressing the "read bootloader code" button while in manufacture mode.
