[Smogglet]

Hi all im trying to get my bootloader code for my huawie p20 lite ANE-LX1 it is currenty running 9.1.0.274 (c7824e5r1p7) (uk) i understand i need to downgrade my phone to 8.0.0 in order to connect to dc unlocker but everytime i try install firmware via sd card method it says install failed iv tried lots of different firmwares all c782 but it still jist says install failed pls help so i can get my bootloader code and root!

Is there a seevice where i can just send my imie number and they will send the code i dont mind waiting a couple days....

Also on a diffrent notr it keeps wanting to me to ota update to a new version 9.1.0.325 maybe there is a way that nobody knows of yet? So im holding off on updating for now.

Thanks for any help!

To get the unlock code you need to do downgrade on 8 android.
Try it with HiSuite
Hcu client support . but old security patch
