Hello guys, anything new regarding changing CN ROM to Global one?

 

[Mr.PvT]

So,
In the end, I was finally able to flash Global ROM over China ROM. All I did was using QFIL (same procedure I described here: https://forum.xda-developers.com/t/help-how-to-solve-frimware-problem.4286635/post-85195767 to get device to bootable state, just with Global ROM.

Phone boots up but after OS is started I get the message that this OS version is not compatible with the hardware (see attached screenshot). Any idea here? I dont think its easily solved...View attachment 5340493

Did you fix the error yet? I had the same problem, even though I unlocked the bootloader

As I searched in Chinese fourms, It seems to flash Global ROM over CN, we must (1) unlock bootloader (2) backup qcn file, edit it and restore it (3) flash.
I found a way to backup qcn file on: https://www.bilibili.com/video/av371118105, It needs root, uses adb shell to force phone open COM5 port so that QFIL can backup and restore qcn files.
And theoritically, we should follow a Korean's instruction on: https://ruinses.tistory.com/2652?category=699524, use HxD find the code that locks the phone in CN, edit it to Global.
However, Duel 2 may be using a different way to lock in CN in qcn, I can't find the Hex-values the Koeran shows. that's the problem.
So is there anyone have a Global Phone to backup a qcn file for us? Most apprieate. I would compare it with CN qcn to find out deferences to ensure how to edit CN qcn to Global qcn.
Or is there anyone knows how Lenovo locks qcn in CN?

by the way, any CN bricks can use this ROM to relive your phone, also found in Chinese fourms: https://meta.box.lenovo.com/v/link/view/26fcb21557f64108a4ba7c3a723f5298
It's ZUI 12.5.535

Do you have a Saviour/Legion Pro 2? Can you provide a QCN backup with your IMEI's/WiFi/Bluetooth and device serial removed? I read the link you provided of the tutorial in Korean and it states you cannot switch back from Global to CN once it has been switched; however, I believe if you have a back of the QCN before you modify it, you should be able to restore it and swap back to a CN build successfully.

Possible to get Android 12 via China rom?

So my question is that is it possible to flash China rom to global version and get OTA upgrade to android 12 as I heard china devices are getting zui 13?

Hi, any luck proceeding further? This seems to be the best way how to do it...
