Help with flashing ROMs on T-Mobile version

I have a T-Mobile branded OnePlus 7 pro, I got the code from T-Mobile and I unlocked the bootloader and flashed TWRP and Magisk. My question is, can I just install any room or do I need to convert to global international using the msm tool first?
If I can just flash directly, how do I install the open Beta? The instructions say to to do it manually in settings, but that's not an option in the T-Mobile ROM, and each ROM seems to have very specific instructions on how to flash using twrp. Thank you for any assistance.

flash OnePlus 7 international rom to tmobile

I have a TMobile OnePlus 7 pro (on cricket) rooted(magisk), unlocked carrier, unlocked bootloader, twrp. Can I flash one of the international custom ROMs (like havoc, crdroid or resurrection more specifically an Android 9 version) without flashing the international firmware? I had problems when I previously tried to convert to international that the phone wouldn't recognize my sim even after taking the OTAs.
If not, one I flash to international firmware and do the ota's can I flash an Android 9 rom over oos 10.x.x? I've been out of the game for awhile and the whole ab partition scheme along with how ROMs are for this phone is a bit confusing. Thanks.

Firstly how did you unlock the bootloader without going to the international oos. What? Unlock sim and bootloader token?

I never had the issue with sim card signal once I updated the oos

Yes I carrier unlocked and then flashed the unlock token.
If I don't flash international can I flash custom ROMs or do I have to flash international first? And I I do flash international and then do the ota's, can I flash a custom android 9 rom ontop of oos 10.x.x(10.3.5 I believe is the newest)?

Your oneplus 7 pro is working on cricket? I unlocked my t-mobile op7 pro via tmobile and flashed the global rom and updated. I sold the phone to a friend and he's on cricket. Cricket is telling him the phone isn't supported but prior to selling it to him I put his sim in it and it worked. Made a call and browsed internet. When he went to set it up after factory reset his sim card got locked by cricket and the phone kept turning off with the only way to power on being holding all buttons to enter fastboot. So if I put the t-mobile rom back on it will his service work?

I flashed the global rom with no issues. Sim card didn't work initially but after the first update it worked no problem. It takes ota's with no problem and I didn't even have to unlock the bootloader. The msm tool and op file did the trick

Reflash back to Original one plus 8t cyberpunk edition ROM

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?

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 How to convert a oneplus 9 tmobile oos12 to pixel experiencie or another rom

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

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?
