After following the tutorial I can confirm that it works on Chinese Rom A13 C.11
You have to download the Chinese C.11 rom instead of the C.08 and once downloaded put the Rollback IN A12
You don't need to unlock the bootloader and you can update via OTA to android 13 C.12 without problems.
I thank @Stano36 for providing me the files, I couldn't download them from 4pda.

Accordingly to what we talked on the other forum topic and the experiments I have done on my device, I think we only need the Indian rollback firmware with the MODIFIED payload_properties.txt file. No need to download the full OTA firmware for our specific device and region.
So, I think it is sufficient to modify the payload text file contained in the Indian rollback package and put it in the root of the internal storage. After that we disable all internet acces, clear data of the "software update" applications from the settings of the phone and install the OnePlus Updater apk according to the android version currently running on our phone and from that application we can directly install the Indian rollback package, no matter what region our phone is.
I will try this procedure tomorrow.
The first time I installed the rollback package it was WITHOUT modifying the payload txt file in it. So I guess this is the reason I lost my Baseband and IMEI numbers.
Tomorrow I'll try with the modified payload txt file and if it installs without losing Baseband and IMEI s then we're good to go. This would be a universal method of switching between regions using that indian rollback package. Universal meaning usable on both devices, GT2 and GT2 Pro and on any region. And more important: WITHOUT the need to have an unlocked bootloader (as there is also a method witch requires an unlocked bootloader).1
Yes. Definitely. Flash the modified Indian rollback package (with edited payload text file), boot into indian build (this is the point where I am losing IMEIs) and after that flash the modified European A.22 build (with edited payload text file as well). Done. Back to Android 12 on the RMX3311 and recovered Baseband and IMEIs.
So yes, this method can be used to rollback for the European model.
Now I am thinking to enable diag port and make a backup of my QCN file, as i now run the A.22 build with functional Baseband and IMEIs, and after that to try once again to flash the Indian rollback and see if I can restore the QCN file with QFIL and recover the IMEIs but also staying in the Indian firmware.
Do you know a valid method to enter diag port on these devices? -
9I AM NOT RESPONSIBLE FOR ANY BRICKS, DO AT YOUR OWN RISK. I TRIED AND WORKED FOR ME.
THIS WILL ERASE ALL DATA FROM YOUR DEVICE.
THIS IS FOR STOCK CHINESE ONLY, I DID NOT TRY IT ON UNLOCKED BOOTLOADER DEVICES, ROOTED DEVICES, OR ANY OTHER SITUATION, SO IDK IF WORKS FOR THAT.
What you gonna need:
android 12 India Rollback:

Full OTA CN A13
https%3A%2F%2Fdisk.yandex.ru%2Fd%2FkCmfvWkxHTLqJA&e=118628786
OP Updater apk
https://forum.xda-developers.com/attachments/oplocalupdate_for_android13-apk-2-zip.5722227/
YES! YOU GONNA NEED BOTH Packages CN A13 and India Roolback
Steps:
- Update your Chinese device to A.13 c.08 normally using the official updater.
- Once you are on A13_C.08 official update turn off All internet of the device.
- Transfer all the files downloaded to Documents folder of your device.
- Go to Settings - Applications - Application Management, press 3 dots, select to show system applications! In the search, enter - Software Update, find it and clear the cache and data in it! Next, in the search, enter - Update Service, find it, and also clear the cache and data in it!
- Install the OP Updater apk
- Place the Full OTA CN A13 zip on the root folder of your device.
- Open the OP updater, press the gear on top. You will see the CN Package listed, tap on it but DO NOT INSTALL (do not touch anything on the popup that will show up)
- Put the OP updater app on Floating Window so it does not close it
- Go to the file manager copy the name of the OTA CN A13 from the root of the device and rename the android 12 India Rollback with the name of the OTA CN A13 you copied
- Delete the OTA CN A13 from the root of the device (or move to another folder) and move the Android 12 India Roolback (that you already renamed) to root folder
- Go back to the floating window OP Updater and press install now
- After process is done you will see a Reboot button, press it and let it do the job.
Done! You should now boot into global ROM India Region.
Thanks to Stano36 for Showing me this on 4PDA Forum and the guy that shared it.
ENJOY YOUR GLOBAL ROM DEVICE2
You forgot to mention that the OTA file must be modified.
In the file
payload_properties.txt
Adjust the value from 0 to 1
oplus_update_engine_verify_disable=01
Yes. Definitely.
