*** Use this at your very own risk.
*** You will lose all data
*** Backup your working modemst1/2 and persist. If you lose these for any reason, it's unique to your device and not recoverable if you didn't back up (via MSM or other people).
*** Read the entire post and follow the steps closely before asking for help. Post all error messages and steps you took. If you just ran a bunch of unknown commands, I would tell you to MSM.
*** Know how to use the MSMTool, Don't start before figuring it out. https://forum.xda-developers.com/t/op9pro-repository-of-msm-unbrick-tools-tmo-glo-in.4272549/
*** DO NOT ATTEMPT THIS IF YOU ARE NOT FAMILIAR WITH ANY STEP DESCRIBED IN THIS GUIDE

General notes:
- NR and LTE bands are read only and not modifiable, not in modem.img or any other partition. You cannot get global bands by flashing a global ROM, nor can you lose TMO bands by flashing another ROM.
- If you wish to unlock the bootloader without unlock_code.bin, you MUST do it from OOS11. If you upgrade to OOS12/OOS13, you will need the unlock_code.
- The T-Mobile NON-HLOS is no longer necessary as of OOS13 release. If you must stay on OOS11 or OOS12, make a backup of the T-Mobile modem partition for the OOS version you want to stay on.
- Dual-SIM does not work.
- This conversion will not SIM unlock you. You can only SIM unlock on a T-Mobile ROM, meaning if you want to do that in the future, you must go back to a TMO ROM (and wipe)
- Familiarity with MSMDownload tools. If the regular MSM tool doesn't work for you, turn back now.
- Back up all data, it will be wiped.
- Conversion: AndroidFileHost (MD5: 8cc3e5e81d15e28bb10dc5f1e7bd4133)
- Run the MSM file normally.
- Unlock your bootloader if necessary. Now is the time if you don't have unlock.bin
- Patch up to Android 13 while on Wifi if your mobile data doesn't work. Use this time to go to another variant (GLO, IN, etc) as needed.

- If your mobile data doesn't work on OOS13, PM me details including HW Revision in About Phone.
- Everything else.
