Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T and OP7TPRO here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 7T bought from T-Mobile.
It can also be used to rollback your phone to a previous release of OOS.

You can download it here: https://www.androidfilehost.com/?fid...26312261632285

It will only work with T-Mobile variant HD1907
After use, your device will be restored to OOS 10.0.3.

Instructions:

Power your device off
Maintain volume up and volume down keys to get into Qualcomm EDL mode.
Launch MsmDownloadTool V4.0.exe.
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds
Enjoy your brand new device

FAQ:

My device isn't detected when I click on "Enum" button

Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c/...e309e6259d.cab (source https://www.catalog.update.microsoft...f-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked in first part of this FAQ.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.

Does this mean that soon we can install international ROM to our phone even without sim unlocking it?

No, it just allows you to go back to stock T-Mobile firmware in case you bricked your device.
