A have the GT2 with the GDPR rom witch i suppose it means I have the European version since I live in Europe. Call recording doesn't work since it is illegal in Europe. Also the APK ment for GT2 Pro doesn't work on GT2, i tested it.
Thanks for the reply. I really want to buy one of the to depending on the call recording availability, its a must for me.
If anybody knows what rom has call recorder please let me know

Unfortunately, you can't install Indian A13 beta over EU ROM. I just tried.

Can someone with Global RMX3301 GT2 Pro (not the RMX3300 Chinese to Global flash) run this in Termux or other CLI and report the value?

getprop ro.build.oplus_nv_id

The stock ROM flash contains multiple super.img files dependent on nv_id
3 x super img files are merged into one for specific region and used for flash
Below is an example for A.16 ROM

Just download the latest firmware and flash it with this tool. If it doesn't work you have to merge the three super files corresponding to the MEA region in one using simg2img, and then you can try fastboot flash super super.img or use lpunpack to extract all the files inside and flash them as you already did for the already prepared ROM in the first post.

I will upload A.16 Global MEA super.img (non-GDPR)
Available here:
https://drive.google.com/drive/folders/1Y5mZtZchLytYqDqs0sOYTqCmaZeURrJ5?usp=sharing
You would need to downgrade from A.17 to A.16. All other flash files apart from super.img are same
It is unclear what exactly are the differences between the regions. It could be just the preloaded apps.

Have you tried running the bootloader lock command in fastboot mode?

"fastboot flashing lock"

Has anyone been able to unlock their bootloader on the export/IN version of A.17. The depth test approves the application but once in fastboot mode the phone will not communicate with PC. Not an issue with the PC either because all my other phones communicate just not this one. Also the android 13 beta gives a "verification failed" and the rollback gives "not compatible with your system" and the factory reset option in settings also doesn't work. Have tried requesting to exit depth test and reapplying and updating platform-tools and still none of these work anymore.

Edit: nvm for some reason I had to update the adb bootloader interface drivers for the phone even tho it had been working on A.16. Turning off developer options also fixed the factory reset not working. Still won't let me use the Android 13 beta or rollback package tho but the guide says the phone has to be on A.14/latest firmware in order to work so maybe that's why.

If you're using the OTA package I posted in my guide, it's only for the EU model. You can use the IN rollback package, but you don't need to be on A.14 to unlock the bootloader anyway.

    I am not responsible for bricked devices, dead SD cards, etc!

    I have not tested the global unlock, Global version unlock thread.

    Make sure you make backups before unlocking the bootloader, as this operation will wipe all user data and apps.
    Make sure your system version is the official and latest one.


    Requirements

    - 60% charge on the phone
    - PC and usb data cable
    - Installed fastboot and proper drivers on your PC

    1. Install Deep Testing Apk attached in this post.
    2. Click on the Apply Now button in order to get approval for bootloader unlock.
    3. Check the status after apply using the Query Approval Status.
    4. If you get an error, force stop the application, change your device language to Chinese and try again (if someone can post screenshot of what to tap, I would update this post)
    5. Once the approval is done, tap Start Testing button, this will reboot your device in the bootloader.
    6. Last chance, make backups at this point otherwise your data is gone.
    7. Run command
    Code:
    fastboot flashing unlock
    8. Done, you can now reboot into system normally

    If I missed anything, kindly comment and I'll update OP.

    OK I have this working. I believe I will now need to relock the bootloader
    Don't relock the bootloader using the ADB lock command. This will brick your device!

    Nope upgrading to A20 doesn't work either. Always get failed to submit in either english or chinese.
    Same problem. It work for me trying all Chinese languages (simple and another two). It seems stuck for like 30 minutes, then idk why I've exit and re enter the app and it worked.
