I've done the debranding from a CLT-AL00(a Chinese retail version) successfully almost 6 months ago. And at that time the ROM version was C432B120 bu can not receive the OTA. So I used the HuRUpdater to manually update the ROM after 2 months and then the ROM is C432B152. Until now, I still can not receive the OTA no matter I relock/unlock the BL. And if I go to the recovery mode, the phone can connect the server, but the recovery ROM version is still C432B120.
As P20Pro can not be downgraded, so I don't try it.
I think maybe Huawei has a database which contains all the IMEIs. And mine is recognized as CN version so can not receive the EU version OTA. Will contact Huawei support for help or flash back to CLT-AL00, but I forgot backup the CN version oeminfo.bin.
