I rebranded from a UK L09 to a euro L29 some time ago. I have just tried a sim from a different provider and its not working. I checked again with the
Original provider who said its been unlocked from day one so never provided a unlock code. They got that from huawei
1. Is it possible that the rebrand had screwed this up?
2. Has anyone rebranded and used other network sims ?
3.is it possible to rebrand back to original UK L09 to see if that cures the issue?
4. Any suggestions to resolve this?

So after screwing things up, turns out it was just the phone not recognising the new sims when the sim lock code was active. Once i disabled that, it recognise the sim immediately. So just a stock phone from now on but given the lack of custom ROM , no big deal. Its still a good phone user wiseWell I used hisuite to rollback to 8.0 and then the new sim was seen. Went back to 9.0 and not recognised again. Tried changing to L09 by using an oeminfo twrp backup from L09 C432. This changed it to an L09 ok but ballsed up the bootloader unlock code so it's no longer re cognised. That's the end of it for me i think. Never again an Huawei,
I'm in the same boat hoping with you, friend. My phone is having issues and I can't update it until I can flash recovery_ramdisk_nocheckP20.img.

I would like to try out this procedure but the link to the files on google drive is broken. Can it be restored? Thanks@ToLive4
Here you go
Please read the pre-requisites prior to attempting this guide.
Please bare in mind that this procedure will completely wipe your device.
A) A P20 Pro
B) ADB / fastboot files and drivers for ADB usage
C) An unlocked bootloader
D) TWRP Installed and functional: fastboot flash recovery_ramdisk name of recovery

F) The ability to use ADB / Fastboot commands to your device - ie: right drivers etc
G) Android debugging and OEM unlocking turned on.
H) Every file in the Google drive link at the bottom of this guide downloaded to your computer.
I) ]NOTE*** If you are on a later firmware than 120, please do not attempt this guide!!
J) NOTE**** There has been 1 known issue with an L-04 device, others have been able to de-brand on L-04 so it's your decision, we don't know if the guide was followed to the letter or not but it ended up unbootable so it's your choice.
1. Copy all these files to the SDCARD section of your phones memory
2. Copy this file to your ADB folder on your Computer
3. Boot your phone into Fastboot mode and open a command prompt on your Computer from your ADB folder, then type:
fastboot flash recovery_ramdisk recovery_ramdisk_nocheckP20.img
4. Reboot your phone so it's in the system
5. Install the Magisk Manager APK on your phone
6. With your phone still turned on in the system and connected to your Computer go back to the CMD / ADB prompt.
7. Type: adb shell
NOTE* Accept the prompt on your P20 Pro by pressing: Grant
8. Type: mkdir /data/local/tmp
Type: mv /sdcard/oeminfo /data/local/tmp
Type: cd /data/local/tmp
Type: chmod +x oeminfo
Type: ./oeminfo CLT-L29 C432 hw/eu
Type: mkdir /data/update/HWOTA
Type: cd /sdcard/
Type: mv *.zip /data/update/HWOTA
9. Copy and paste this whole section into the CMD prompt, make sure there are no spaces before or after the script.
echo "--update_package=/data/update/HWOTA/update.zip" > /cache/recovery/command
echo "--update_package=/data/update/HWOTA/update_data_public.zip" >> /cache/recovery/command
echo "--update_package=/data/update/HWOTA/update_all_hw.zip" >> /cache/recovery/command
10. Type: Exit
Type: adb reboot recovery
Finally. The device will now reboot and will begin the de-brand process, you'll see a percentage and an EMUI sign with the words "Installing update.."
Allow it to finish, do not interrupt the process.
Once complete, It'll say update success and the device will now reboot
*NOTE: I got an error saying "No SD card or USB device please connect in 2 minutes!" with a percentage moving round from 0 - 100% but it still worked.
Allow the device to continue and it'll perform a factory reset
The device will then boot
Your device will now have the following model and firmware
Build: CLT -L29 184.108.40.206(C432)
