Downgrade and flash Huawei

DUB-LX2 Y7 PRO 2019

The cause of downgrade is imei repair
and to solve the problem of lack of voice calls after the Downgrade

*Flashing will be done in EDL mode becuse the device is Qualcomm based .

Below is a picture for test point .

You MUST follow procedure step by step to get success .

*First reomve battery connecter and connect test points then attach USB CABLE.

*You have to notice that when the process of flashing is started the Dongle will do some work and will reboot device into fastboot mode , Now we have to reconnect battery (timing is very important) so the device will get into fastboot mode. and then the Dongle will continue the process od unbick and device will bootup successfully .

Now device will work with No Voice Calls and some bugs .

So we have to flash Board firmware exclusing files we already pointed to in picture below :

We have to use the same procedure mentioned above and marked with *

Once Board firmware flashing is done , device will boot up without IMEI so we have to flash any stock rom with SD Card Or via EFT Pro .. and device will be woorking like a charm.
