HUAWEI NOVA 2 PLUS (BAC-AL00 -_ BAC-L21) CONVERT AND HUAWEI ID REMOVE

HUAWEI NOVA 2 PLUS (BAC-AL00 -_ BAC-L21) CONVERT AND HUAWEI ID REMOVE

Problem Solved!!! 

Phone downgraded, converted to BAC-L21 and Huawei ID removed.

The key was after flash with BAC-L21 and white error screeen you have to flash again same firmware in FASTBOOT mode. 


To resume steps taken with this BAC-AL00 with HWID were:

1. Downgrade using Resurrector with TP and BAC-Downgrade-Board-1024.fcff

2. Changed Model/Vendor/Country to BAC-L21/hw/meafnaf with FlyCaptain

3. Flashed BAC-L21 8.0.0.330 firmware (low version for repair purposes) in UPGRADE mode with Resurrector (you probably will have white error screen after this step, if not skip to step 5)

4. Flash again BAC-L21 8.0.0.330 firmware in FASTBOOT MODE using Resurrector (it will write recovery partitions in fastboot and change phone to upgrade mode atomatically to complete flashing process)

5. Remove Huawei ID with FlyCaptain

6. Optional upgrade phone to last firmware available.

That's all!! Phone working 100%
