HI guys,
so as u all know, we cant do OTA updates for this model if we flashed to global rom,
is there anyway to revert back to the original ROM/OS and relock it?
we can just down the APK For playstore and install in it right?
See my thread here:
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?

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
Good evening,
Is it possible to recover from where I am (LE2117 model on OxygenOS 11.2.10.10.LE25AA, OTA Version OnePlus9Oxygen_22.O.13_GLO_0130_2111112106), or is my only option to be stuck on the OnePlus 9 Pro 5G India version for locked bootloader? If it's possible, what do I need to do? Work demands my phone to not be rooted...I'm not married to the concept of global or India region, and am fine with either.
[Marking each area with a reference at the bottom...]
Problem: I've attempted the OnePlus 9 5G T-Mobile to Global transition [REF001] on my LE2117 only to brick my phone midway through the process. The goal here is to get the phone on a NON-T-Mobile variant with a locked bootloader. Thankfully I'm rid of T-Mobile, at least...
Where I am now: I was able to recover the phone by using the MSM tool for OnePlus 9 Pro 5G India [REF002], then using the T-Mobile to Global "flash_all.bat" script [REF001] again with the payload of the global version [REF003]. The issue is that the phone's bootloader isn't locked, and if I lock it then everything is gone and I must start over at the beginning of this paragraph. I've attempted using the global MSM tool [REF004], but the issue is that it provides a Param Preload error for Unsupported Target IN. There was a reference somewhere about flashing the param.bin, though, that didn't seem to work...
Thank you for your insight and assistance!

Run the Indian 9 Pro MSM again and download the global 9 downgrade package in the pinned post and flash that to get back on global firmware. The MSM re-locks the bootloader as part of the process and you don't need an unlocked bootloader to convert between variants if you use the official local upgrade function.
Thank you for your response EtherealRemnant -
I've followed the steps and am probably doing something wrong. I've run the OP9PRO India MSM, unlocked OEM for the flash (because trying local upgrade (downgrade) at this point doesn't show the packages), flashed to either global downgrade package, and attempted the global MSM tool for re-lock. I'm still getting the Unsupported Target IN or Device Not Match Image error. Which part of this am I doing incorrectly?

You may actually be running into the same problem I did with the downgrade package where it just vanishes from the storage. Do it like this on your computer:
adb push packagename.zip /sdcard/
When I did this, it didn't mysteriously vanish anymore.
If this doesn't work, you may unfortunately be stuck unless you can get someone to modify an MSM Tool for your purposes.
Finally, a solution that hopefully others can also follow to install different versions of their official builds as well (just exchange REF004 with your appropriate compressed zip containing the payload.bin.):
[Adding references for those who found themselves in my same predicament...]
After utilizing the MSM Download Tool for OnePlus 9 Pro 5G [India Region] [REF001], I unlocked the bootloader and leveraged the TWRP App for OnePlus 9 [REF002] by booting towards it [REF003] and installing/flashing the latest version of the OnePlus 9 5G [Global] [REF004] (it defaulted to slot B.) Re-locking the bootloader [REF005] allowed the phone to automatically wipe, and boot directly into the latest Global install.
Shout-out to ctonylee1965's post that's nearly buried in an off-related thread, or I wouldn't have found this solution.

Got back to global. Took me a day to figure it out. Enable OEM Unlock and USB debugging. I flashed temp TWRP, installed the OS Zip file from OnePlus support site. Rebooted into recovery, formatted and wiped system. Booted into global. This installation is in SLOT B. Slot A will still have horrible Indian Rom (only horrible because it shouldn't be installed on my Global Unlocked Phone, no disrespect to my Indian brothers.) Note when logging in for the first time let global do its OTA update before you do anything else, especially before you reboot. The Indian version is installed in slot A. REBOOT after OTA installed. Don't reboot before OTA does its thing. This will ensure Slot A has a clean installation. I made the mistake of rebooting before the OTA and I could not do anything with slot A. Relock the bootloader, it will wipe and you will boot into a pristine Global OS 11.2.8.8 Rom.

Hi everyone,
Unfortunately I had a bricked Oneplus 9 device with only EDL mode. I was able to MSMTool with the indian Oneplus 9 Pro version.
Afterwards I used another bundled MSM package to install Oneplus 9 firmware. On which I'm now stuck.
I tried to use Oxygen Updater to download and install the latest EU update but it throws errors. Can anyone help me please?
Thank you!!!
You can try doing MSM to Global, then in Local upgrade you can switch versions. Good luck
If you're stuck on Indian firmware, use my modded MSM Tool.
[Locked] Global 11.2.10.10 MSM Tool (added experimental support for Indian variant flashing as well)
This method is outdated. You must use this method or you will run into problems...

Hi everyone! I have a question! Does anyone know how to install a custom rom on the oneplus 9 t mobile with OOS 12? Do I have to downgrade or can I install a rom that has android 12 by default?
My version its LE2117_11_C.19
You should firstly update to the latest OOS12 update TMo gives us. After that unlock bootloader (as per the guide here on the fourms) via unlock code method (you will have to wait for TMo to send that your way as it's device specific) and then follow the instructions from the rom provider.
I'm running StagOS on my TMo OnePlus 9 without issues since their last release, before that ran Lineage, Jaguar, Nameless. As long as you are updated to latest OOS and with an unlocked bootloader, you can flash any rom on here provided you follow their instructions. If you brick your phone you can use the modified MSM tool I posted on one of my threads to un-brick and bring back to life your phone (keep a backup of your data though)

so can i follow any tutorial to install any rom if i have unlocked bootloader next to sim? since I tried once to change to global and it worked, I put a module and my cell phone and the phone bricked, with the MSM Tool I was able to recover the OOS t mobile version, but I thought I had to downgrades OOS 11 to install any rom and I never did anything again because of fear for the brick
sorry for my bad English

Yes, that's it. Basically have your phone updated to the latest OxygenOS TMobile can give you,; Have your phone SIM Unlocked AND Bootloader Unlocked and then follow all the steps the Developers of the ROM you choose give for the installation.
If any rom specifically asks for OxygenOS 11, then the same steps are applied except instead of latest OS versión, the one the Dev asks for
Then I will start the installation of some rom that I like on top of the latest update of tmobile OOS 12, do you recommend any specific one that is pixel experience or similar performance?

For example, when I go to the official lineageOS 19.1 page, it says that the compatible devices are all except mine LE2117, do I continue to install anyway?
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
