[easy-team]

Hello every one :
when facing such error in Huawei Downgrade Android 10 Process:

Bypassing downgrade protection.....Failed: writing failed, Please contact support team

Do the following:

1- Read info and check if your device model, android version and customization code are the same both on Device and Downgrade firmware.

2- If yes then move to second step which is to flash Stock Android 10 same as in your device via SD card or OTG then do repeat downgrade process again .

3- You can also try downgrading by flashing the AOD files via Flash Multi app files .. by adding files one by one A then O then D the put device in upgrade mode and flash ..

4- If not solved then make your own thread providing relevant images and logs and we will be glad to help .


Best Regards!
