[GUIDE] How to convert TMobile OP7 to International.

First of all this is not my work I only tested theirs.
Credit to @themustached for finding that a patched .ops was the solution.
This guy doesn't even have the damn phone yet and did this for us so show some love. You can donate to him through paypal here - http://paypal.me/dustinwann
Also @Eliminater74 @jkyoho and others for their hard work and dedication to this conversion.

Disclaimer: I do not take responsibility for any damage done to your device by using this procedure. Everyone has problems sometimes so be civil and ask clear questions explaining where you failed if you expect help.
These instructions will convert your TMOBILE Oneplus 7 PRO to the International version of the phone.
This lets you unlock the bootloader, root, twrp etc.. Sim unlock is still being worked on.

Take a breath, drop the hype and read every single step before you even plug your phone into the PC.
These steps assume you understand you lose all data on the device, are sim unlocked, have the Download mode drivers installed, adb and fastboot and your device powered OFF.

1) Download both of these archives and extract them to a folder you can locate. - https://mega.nz/#!289BVITR https://mega.nz/#!St1DiShb Mirror - https://www.androidfilehost.com/?w=files&flid=294946

2) Open the MSM tool and uncheck the box next to SHA 256.

3) Hold both volume buttons for 5 seconds then plug in the USB cable. OR In ADB type "adb reboot edl".

4) Watch the MSM tool and the second it says *Connected* next to one of the COM ports, press START.

5) DO NOT unplug the device until after it says Success in green.

6) Once the phone boots into the system, go through all the setup options.

7) Enable Developer Options and enable OEM Unlocking.

8) Enter bootloader mode on your device and type "fastboot oem unlock".

You now have an unlocked international OP7.
If you want to root and install twrp dont take the OTA yet.

-Follow these two threads below then take the OTA, do that after you root and twrp. You can preserve root by going into Magisk Manager after the OTA installs, then press the top Install button on the right and use the after OTA option.
This will put you on the latest version with twrp, root and working sound/wifi.

*Future proofing Update*
Hot off the press. Here is a tool that will allow you to patch an ops file without having to download a new modified one every update.
You can use this with a stock MSM or the modified one linked above. Must be run on an unmodified ops..
Global
EU
China

1) Extract the Patcher into the same directory as your MSM tool and OPS firmware.
2) Launch the Patcher as admin. Now select the ops you want to patch and check all the boxes under Patch Options and click Start.

3) Once it finishes you will be able to flash the ops file from the stock MSM or the modded one above.

~FAQ~
~Not fast enough to start flash
If you press Start on the MSMTool it will "wait for device".
Doing this will make the flash start right when the phone enters EDL.


~MSM is getting stuck on Param Preload or something similar.
This can be caused by having old Oneplus L2 drivers from a different model installed.
-Follow the steps up until MSM gets stuck. Open Device Manager, right click on the Qualcomm device under the COM section.
Click Uninstall but do not check the box to delete the driver, then click Scan for Hardware changes. Now go to the folder you extracted the L2 driver to, right click the inf file and click Install.
You should be able to use the MSM tool right away but may need to exit and re-open. Also restart back into EDL if needed.
