Fix (Please contact support team) When Downgrade Huawei Android 10 with EFT Pro

Hello everyone

Some times when we try to downgrade Huawei Android 10 device we got this error :

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

First make sure that your device mode, downgrade file and selected model in EFT Pro are identical , if all OK*move to next*step

Put device in Upgrade Mode by pressing Vol+ & Vol- and connect USB*cable

If device software is faulty after the downgrade failure and not going into Upgrade and instead it goes into recovery* mode or showing below*error

Then Do the following

Turn off device completely then press Vol+ and connect USB cable while keep pressing Vol+ for 30 seconds

Device will get into this mode then we select Update Mode

Then select USB Upgrade mode

Then device will get into Upgrade Mode
