How to change Regions with the new oxygen os 12? - OnePlus 8T Questions & Answers

Hi,
I installed the in version of oxygen os12 on my eu 8t by accident. How can I can't it back to eu (when eu releases)?

I suppose that OOS12 won't let you flash EU version of the same firmware, as it was on OOS11.
So, there are several options, as i see it:
1. MSM to OOS11, then update to OOS12 EU (but you will loose your data, unless you backup).
2. Wait for the next update and flash EU version.
3. As there is no working TWRP under OOS12 with data decryption now, you can try to flash OOS12 EU via fastboot, though i'm not sure, you will succeed, as it is untested at the time of writing.

Another option is to use the downgrade package to go back to OOS 11

Oneplus 8T (Cyberpunk Edition)
I received a Oneplus 8t (Cyberpunk Edition). The phone was supposed to have HydrogenOS as it is a Chinese phone. However, the vendor installed Global OxygenOS (KB05AA). After OTA updates, the phone wouldn't reboot and would get stuck on the...

You can use the MSM Download Tool, following the instructions (to reinstall the original HydrogenOS). We're finding a solution to install Google Apps, since you'd ideally want TWRP (which isn't out yet). The fix will require unlocked bootloader/root.
How can i return from 8T Cyberpunk to 8T EU? Flashing msm not help.
anyone with the OS i can DL from and just flash to my current phone? does it work that way?

Question Oneplus 9 | LE2113 | 11.2.4.4.LE25AA | How do I convert to EU firmware

Hi there, I bought a Oneplus 9 (12/256) directly from Oneplus Singapore. Everything is great except for the fact that I hoped to update the software to a newer version ( 11.2.7.7 / 11.2.6.6 ) to enjoy the bug fixes and improvements.
The phone came on 11.2.3.3.LE25AA
The default system update showed that it was the latest version.
Okay......then I learnt about Oxygen Updater and used it to update to 11.2.4.4.LE25AA
However, when I proceeded to update further to 11.2.5.5, the app was still showing me that the latest software is 11.2.4.4 (What??)
I then learnt that my phone was running on Global Firmware which was stuck on 11.2.4.4 and though the incremental update from 11.2.5.5 to 11.2.6.6 was available, without being able to update to 11.2.5.5, I was stuck on 11.2.4.4...........
Then I researched my model number and realised that LE2113 meant my Oneplus 9 (purchased directly from Oneplus) was the EU variant.....running the Global firmware......sigh......
So here I am now, seeking advice from you knowledgeable folks, how do I go about getting my phone to run on the EU firmware so that I can enjoy faster(?) updates.
Is it as simple as downloading the full zip of 11.2.6.6.LE25BA from Oxygen Updater and using Local Upgrade in the default System Update? Will this wipe my data?
Or will I have to root/flash or something complicated
Just flash the full BA zip.

By flash, are you referring to the system updater in the settings app?

Can I install Oxygen OS 11 Indian Rom on KB2000?

As the title says , I've OnePlus 8T KB2000. Currently I'm using the international global version of Oxygen OS (KB05AA). Can I change it to Indian variant?
Yes you can. Easiest way is to flash a full indian OTA package through the local update function in system updater. That should work as long as indian OTA have the same or higher version number compared to your currently installed global version.
If that don't work you can always extract the partitions from the payload.bin in the indian OTA zip and flash through fastboot. Following this guide https://forum.xda-developers.com/t/guide-unbrick-or-restore-to-oos-using-only-fastboot.4289013/

Question LE2115 return to stock

Hello,
Just got a Oneplus 9 today. Installed Jaguar to try it out. Wanted to go back to stock to compare a few things.
I grabbed the "stock" files and tried to flash using this guide: https://forum.xda-developers.com/t/fastboot-rom-pc-required-op9-stock-oos-11-2-2-2aa.4275727/
This bricked the phone.
I was able to restore the phone via MSM using the Indian one (lemonadep_22_I.07_210412), but in OxygenOS it states the Phone is a 9 Pro.
I tried flashing the STOCK file again just to see (since I now know I can recover in EDL), but it bricked the phone again.
This allowed me to confirm that for Global LE2115, the European MSM (lemonadep_22_E.05_210324) also works to restore the device!
Unfortunately again, it says the Phone is a 9 Pro.
How would I proceed if I wanted to return a LE2115 to stock and relock the bootloader?
Thanks

Copy pasta:
To get back to global firmware, flash this in the local upgrade tool.
https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
It is the global downgrade package. It will wipe your phone and when it comes back, you will be back on global software.
After you flash that, go to OTA upgrade and it will say it's going to download C.48 but it will actually install 11.2.10.10 and then you will have the latest OOS11.

Can confirm this works!
I used the unnbrick tool from one community server and restored my one plus 9 5g 2115.to stock and locked the bootoader. But I could not get to install any rom because it always took me to crash dump. Hope it helps to get back to proper version for you
