Is there anyway to change the TMobile stock software to global oxygen OS, has anyone ever tried to rebrand the Oneplus 8 TMobile to global version?

I have purchased a Chinese variant (KB2000, late December 2020) of the OnePlus 8T which out of the box is running HydrogenOS 11.0.5.6KB05. I downloaded the Global ROM (OxygenOS 11.0.5.6.KB05AA) from OnePlus' website to do the local update, but cannot install as it is saying it is a previous version.
I have been scouring the internet as trying to figure out options, but it seems like I have 2 options:
1. Wait until the Global ROM version is higher than the current HydrogenOS version (11.0.5.6KB05) and do a local update. Note that the unit wants to update, but not letting it.
2. Use the BootlLoader installation method to install a fresh OxygenOS. I found what seems to be a great guides at https://www.thecustomdroid.com/oneplus-8-pro-oxygenos-restoration-guide/ or https://www.droidwin.com/restore-oneplus-8-stock-oxygenos-fastboot-commands/.
Note that I don't want to Root or install any custom mods or ROM, but just want to use the latest Global ROM on this phone.
Any insight will be greatly appreciated as I have been researching, but not finding a definitive answer. Thanks in advance!
If you are fine with wiping your phone you should be able to use the msm tools from the unbrick tools thread to convert

Ok thanks for the feedback and will search for the thread. I'm fine with wiping it as it is a new phone. I'll update how it goes.

Hello. I am fairly technical with web and computers but not so much when it comes to android or mobile hardware/sofware so bare with me.
I got my oneplus 7 pro 5g (UK EE network) back from repair yesterday and went to install lineage os on it following this tutorial https://wiki.lineageos.org/devices/guacamole/install with OpenGApps nano.
The install seemed to go fine and managed to boot into lineage, connected to wifi and then started installing my apps etc. Today I moved my sim over and could not get the phone to recognise the sim. Could not turn on mobile data, could not see a phone number in the about settings page etc.
I then started googling around and found this thread [OP7P] [Latest: 11.0.3.1] Android 11 Firmware collection | XDA Forums and in my limited wisdom decided to just start flashing the global firmware onto the device. After this lineage booted fine but now not only no sim/mobile network but also no wifi. I assume i have put the wrong firmware onto the device, maybe something to do with either my phone being a UK phone or the fact that it has a different modem for the 5g version of it.
I think it's time I asked some people who know what they are talking about rather than trusting my own poor judgement :/ Does anyone know how I can fix the wifi and sim on this device now? I dont mind if it is on lineage os or if it goes back to oxygen os.
Device OnePlus 7Pro 5g | Model: GM1917 | Build: lineage_guacamole-userdebug 11 RQ3A.210905.001 10035588
The OnePlus 7 Pro 5G doesn't have working modem on custom ROMs past Android 10, and me and others efforts to get it working have failed. This is due to different modem and partitions. You also cannot flash the international firmware on it. This will most likely break modem even more. The best you can do is flash the EU5G firmware going by GM27BA. (Found here https://forum.xda-developers.com/t/...rint-oneplus-7-pro-5g-to-european-fw.4042583/). Also Android 11 is not out and probably will never be out. The source for the 7 Pro 5G isn't even fully out so building custom ROMs won't work
Thanks for the info and the link. I really appreciate it.

So if I were to go back to stock oxygen os would that fix my modem alone or will I need to fix the firmware separately since I flashed the global firmware over the top?

Done! Just going through android initial setup now but it is registering my sim and wifi. You absolute legend. Thank you so much for your help.
Try YAAP custom ROM , works brilliantly
Even on the newest stable OOS12 build (C40) the touchscreen still doesn't work as well as the sim card.
While the Indian 9pro msm method was able to unbrick my phone, it seems to have broken the firmware in a weird way. I flashed the global stock OOS11 rom and thought I returned my phone back to it's out of the box state. One thing I noticed was the country code when logging into the community app was locked in for India. Then of course when I updated to android 12 (C39, then C40), I cannot use the touchscreen and the sim won't work. Is there any way to fix this? I can still use my phone via USB OTG.
How did you flash global stock oos11 rom? Did you use fastboot or the global msm tool? Also what version of the oneplus 9 do you have?

I have the global NA OnePlus 9. In my post above I used fastboot to flash global oos11 using this tutorial but keep in mind you can't update to android 12 with this method and you won't have a "pure" oos11 rom.
I've since come across a better method that fixed all my issues, getting me to the truly pure out of the box global oos11 rom (which now updates to oos12 flawlessly). See here.
Note the param part, I am pretty sure the aa file he provided is only for the north American global op9.
Long story short, I bricked my device today, had to use the Indian 9 Pro firmware to fix it as the global MSM wasn't recognizing it, and was very frustrated I couldn't go back to full global firmware.
I figured out how to fix this. Just use it like any other MSM Tool, click the dropdown in the left and switch to IN.
This isn't a technical support thread, there are plenty of threads around here for the MSM Tool and the issues that arise when trying to use it. As you can see, I didn't have to use the lite firehose even but most people seem to have problems if they don't so just do what worked for you before.
Also, this is not for people who haven't flashed their global variant with the Indian 9 Pro variant. I'm not responsible if you mess up your device by flashing it to a real Indian 9 Pro or under any other circumstances!
EDIT: Also, I tested it just now, and this successfully updated to 11.2.10.10 and then C.48 with working touchscreen using the stock OTA updater!
EDIT2: I can also confirm that the original global MSM Tool works again after flashing this so my device was 100% returned to a stock global unit.

So I've got a TMobile OnePlus 9 that's been converted to the global ROM. From here what's the easiest way to get updated to stock OxygenOS Android 13? When I run the system update in settings it'll update to Android 12 but the phone says that there's no sim card in. Am I doing something wrong? I don't mind unlocking the bootloader and flaking a recovery if there's a stock rooted zip I can flash.
I've tried myself but updating anything to 12 and up my touchscreen stops working, but using the TMobile India modded MSM should work getting to the global rom "but now realizing it was cuz I used something else to recover from a brick" but here
Safely convert regions (includes T-Mobile) as well as restore the ability to use OOS12 after using Indian MSM to recover from a brick (Windows only)
It seems lots of us have had to use the India 9 Pro MSM to recover our devices and in the process, we lose the ability to go back to OOS12 or ROMs based on that firmware because the touchscreen stops working and also trying to convert T-Mobile...

thanks I'll ck it out
this doesn't work for my device le2119 the mod fix zip throws an error unsupported device eu. I made the mistake of activating slot b. is there any way of switching back without fastboot. all I get is a black screen no matter what button combo I press. I can only get edl and I'd rather not flash the eu msm again.

ive gotten the same error too, im on 11.2.10.10, but cant upgrade to OOS12/13 without the touchscreen breaking/dual sim bug, i forgot the link to the 9 pro india msm to flash it with, but ive tried flashing one that was 9 pro and kept getting "device not match image", no clue why
I just read somewhere that downgrading to 11.2.2.2 may work but only place I can find that firmware is on some Chinese site. I can flash the eu pro version all day long. but now I tried flashing an India mod firmware with no success and reflasjed eu again but phone is stuck at 0% power and all I get is a bootloop
