Thank you mcandre for yr reply. I have read the manual and find:

1- You may use Remove FRP feature on Service tab, it reads the phone information from Fastboot mode.
My phone is:
Phone model: VOG-L29
Version: :VOG-L29 9.1.0.178(C431E4R2P2)

2- STEP 3: Prepare the downgrade *.skf file
You can download the downgrade *.skf files from bootloader.com, free section -> Huawei -> Downgrade files, or here (installer with addons for all models).
The chosen downgrade file has to:
exactly fit your phone model and Android version
be the SAME firmware version as is in the phone now
be the same customization version

this mean I need a downgrade file like: VOG-L29_9.1.0_C431.skf but in bootloader.com, free section -> Huawei -> Downgrade files I found just 2 files VOG-L09C_9.1.0_C431.skf
and VOG-L29C_10.0.0_C431.skf. the both files do NOT much my phone

My question: which *.skf file should I use to downgrade this mobile?

Best regards

Use this SKF for downgrading: VOG-L09C_9.1.0_C431.skf

Use suitable flash files, lover version.
