change of cust after updating 10 - Huawei Mate 20 Pro Questions & Answers

Hello, when I update to emui 10, I change my CUST to LYA L29 CUST 432 and my cell phone is LYA L29 CUST 605, since I have another CUST, I do not receive OTAS nor can I do rollback since it causes me softbrick, as I can put the corresponding cust to my phone?

Debrand Honor 7 Chinese version (PLK-TL01H) to European Version (PLK-L01)

Hi,
I'm trying to debrand my chinese version of Huawei Honor 7 (PLK-TL01H) to European Version (PLK-L01).
As i'm already in Marshmallow version, i should do the following:
1) Downgrade to Android 5.0 PLK-TL01H B190
2) Root the phone thanks to honor 7 MultiTool
3) Flash PLK-L01 B180 version via 3btn force update
4) Flash PLK-L01 B370 version via force update.
I'm trying to rollback (first step) with the file update.app that is B190 version. But i'm already struggling:
1) Force update with *#*#2846579#*#*->select Software Upgrade->select SDCard Upgrade
2) Force update using local update option in settings doesn't work (the option is not available)
3) 3btn give me access to TWRP and not to Force update option (recovery)
I also tried to flash stock recovery, then force update works but stuck at 5% with no error message.
Any idea how to rollback to B190?
Thanks,
Flash the stock recovery of B370 (I assumed it's your current rom) by using "fastboot flash recovery recovery.img" command.
After that, downgrade to B300 and install PLK-TL01H B190 (if your brand is not plk-l01). If it's, first you need to install PLK-L01 B180.
Hi,
can you just be a bit more specific and detail me the steps and how to do? Thank you,

Does flashing stock recovery and force updating gets stuck at 5% using 3 button method?
If yes, I had the same problem, I booted into Android and used the *#*#xxxxxx#*#* method and it worked ok.
May be you can give that a try....

A quick guide to root Honor View 10

I've spent a lot of time to get root my Honor V10. I guess this guide would be usefull for other Huawei devices.
First of all you need to fix the bootloader. I used HCU-client to read de bootloader code and after that I was able to unlock de bootloader via fastboot command:
Huawei bootloader code read via testpoint – HCU Client
hcu-client.com
Secondly I downloaded an online firmware of Android 9.0. Android 10.0 doesn't work for this purpose.
Huawei Honor 10 COL-L29 hw eu HLRCF Columbia-L29D 9.1.0.353(C432E5R1P13T8) Firmware 9.0.0 r3 EMUI9.1.0 05015CPS [androidhost.ru].zip - AndroidHost.RU
Download file - Huawei Honor 10 COL-L29 hw eu HLRCF Columbia-L29D 9.1.0.353(C432E5R1P13T8) Firmware 9.0.0 r3 EMUI9.1.0 05015CPS [androidhost.ru].zip
androidhost.ru
This firmware is needed for either install on the device and for generate the RECOVERY_RAMDIS.img
To generate the RECOVERY_RAMDIS you will need this application: HuaweiUpdateExtractor_0.9.9.5
To install the firmware on the device a SD card or a usb via OTG is requiered.
Finally, you must install Magisk and patch de RECOVERY_RAMDIS.img using Magisk. After that You should connect the device via USB to the computer and exec next instruction on fastboot:
.\fastboot.exe flash recovery_ramdisk .\RECOVERY_RAMDIS_PATCHED.img
