I cannot for the life of me get MSM to recognize my T-Mobile OnePlus 7 Pro. I have installed adb fastboot and OP7 Pro drivers and it will not pop up. Can we get a list of recommended ADB and driver installers?

Back on T-Mobile now thank's to this amazing Community. Some steps to help others.
Step 1- Download the file in the original post, create a folder somewhere you know where it is and extract the downloaded files to that folder
Step 2-Turn off your OP7 Pro
Step 3-Open the folder you created and right click on MsMDownloadTool V4.0.88.exe and select run as administrator, Once open uncheck sha256 check.
Step 4-Plug the Original USB cable that came with your phone into the phone.
Step-5-Hold the Power/Volume up/Volume down button until you see Connected in MsMDownloadTool, the instant you see Connected press start. You only have 5 seconds before it's too late so be quick.
Step-6 Once you see "Download Complete" in green in the Status of Communication box in MsMDownloadTool the phone will automatically reboot and you should have the TMobile splash screen and be able to set the phone up through the set up Wizard.

That's it you are done.
Any idea why I won't see connected in the MSM tool, ever? Fastboot works. Any idea how to get this to work with the qdl tool in Linux?

I have a OP7Pro that is converted from TMO to INT and it was a 1 SIM variant. However, in the int version it has 2 sims and 2 IMEI no. but they are identical. Does anyone know if I convert back to TMO would it change back to single SIM and show only 1 IMEI?

Yes! When dual-SIM is enabled on the single SIM device. It uses the same IMEI for both SIM slots. Converting back to single SIM will only show the one SIM slot with that IMEI.

Here is the tool needed to flash the Oneplus 7 Pro - TMobile version back to stock.
If you converted to international already and want to go back or recover from brick, this is for you.

TMO MSM rar

The same steps apply to this as the other MSM tool.
You can follow the guide from my other post if needed.

    I still can't figure out how to go from unlocked international to TMobile. I had a hex editor to look at the files but can't figure out what to change in the file.

    If you really, really want, I can make you a converter later today. I would need you to test it (I do not have a GM1917, I have a GM1915, and the difference matters) but there would be no risk of bricking - if I make a mistake, the MSMtool will just not flash my file. Are you up for this?

    FYI, I am the DT the OP references as being involved in this MSM Tool release. Praise me XD

    As staff insists on editing my posts, I am done sharing anything here. I’ll drop the OnePlus 7 MSMtool sometime next week and that’s it, adios. Hope it was worth it, staff.
