0 Shares

Hello, guys! I just want to share a solution to bypass FRP lock of HUAWEI NOVA 5T with firmware version ‪YAL-L61 10.1.0.249(C431E3R1P2)‬. So first of all i started with downgrading the phone to version: 10.0.0.184(C431E3R1P2)‬ – the file is available at the support server of Octoplus named YAL-L21 10.0.0.184(C431E3R1P2)_Firmware_EMUI10.0.0_05016FJ E.zip. I managed to downgrade it using a type-C usb on the go but i guess a sd card should work too. After that i used Octoplus HUAWEI tool to downgrade to 9.1.0 again with a file from the support named YAL-L21(C431) Downgrade from 10.0.0 to 9.1.0 for Reset FRP(Octoplus).zip, there are instructions for the operation in the .zip file. Here is the log of the operation:
