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

[easy-team]

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



Now navigate to Huawei >>Flash>>

Flash Multi App files ( Upgrade Mode)

Load the*files

A O D*

one after one then flash device (upgrade mode)

wait till process finish and your done








Best Regards

X is changeable so it could be 1 or 2 or 3 , thats why it is X

Just tested with SNE-Lx1 10.0.0 [ C432 / 170 ]...

Yes - "Downgrade to Reset FRP (Upgrade mode)" with AOD breaks at first file. No way to flash phone anymore even via eRecovery, SD card or USB.

But... repeating procedure as is write in post 1 by easy-team manager work .
Just put back phone to upgrade mode and with "Flash Multi APP files (Upgrade mode)" repeat procedure AOD and phone will be alive again. If you have FRP locked unit, then put it back to upgrade mode and flash again via "Flash Multi ..." step 2 files 1.APP and 2.APP. Reboot to recovery and use "Safe mode" method to reset device.

Flashing AOD is not the reason as hundreads if users are already used the method . maybe you used a wrong file ?

Why you boys do not read exactly word by word post #1 and do it exactly same? I was test it and can say - it's only correct way.
