This method will erase everything in your device, make backup before update!
Download the firmware by this link https://androidhost.ru/1lpz or search ''Charlotte''
Extract the zip
Format your USB Stick to ex-FAT
Create a new folder named ''dload'' and move the files extracted as the picture

Now on your phone, Open the dialer and call -> *#*#2846579#*#* -> ProjectMenu-> Software Upgrade-> SDCard Upgrade-> OK.

Wait.. and:

I would remove the screenshot, your IMEI number is clearly visible.

Yes, its C432, CLT-L09, i delete the L29 folder, pluged the otg, was verifying the package and said, error verifying, but after that bootloader bricked, i cant do nothing i sent the phone to huawei warranty.

I think it was because the phone had low battery, only 30%, and the update was stopped with no battery, so remember to update with full battery

Be careful what you download and where from. A version I installed worked perfectly but locked my bootloader.

Version 9.1.0.311

For me I didn't save my code so I'm screwed.

Don't really care because I'm selling it. But just a heads up.

This code don't seem to work for me. Is there another to access this hidden
menu?
