Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7 and OP7PRO here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 7T.
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...26312261610653

It should work with HD1900 (Chinese variant), HD1901 (Indian variant), HD1903 (European variant) and 1905 (North America variant) models.
After use, your device will be restored to OOS 10.0.4.

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 Target Button
Select "O2" (if you wish to go back to global firmware) or "India" (if you wish to go back to go back to Indian specific firmware with feature such as Work/Life balance)
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds
Enjoy your brand new device

FAQ:

I see a target button, what is that?

As you may (or may not!) be aware there are starting from 7T-Series build specifics to India.
Selecting "O2" as target should give you the global firmware while selecting "India" as target should give you the Indian one. See https://i.imgur.com/2ipNyIy.png for a screenshot.

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.

Awesome! Now we wait for the ability to convert the T-Mobile version to the International version.

There's probably some potential if T-Mobile one got released. Not to mention that in case something goes wrong it will be nice for you to be able to go back to T-Mobile firmware.

Even if I don't own the devices, I remember that what was done six months ago for the 7 Pro was patching the OPS file directly and unchecking SHA256 check box in MSM tool window as OnePlus implemented additional protections disallowing to patch the .exe directly in the same way at what was done for the 6T. My guess is same will have to be done for 7T.

Unsupported Target EU
Thanks a lot for providing this for all of us!

However, I just did it and it stopped after 6s stating: "Unsupported Target EU". Does this have something to do with my device being the EU-Version? Doesn't the MSM Tool work for my device?

That might be due to that indeed and that's very weird as for OnePlus 7 and OnePlus 7 Pro MSM tools allowed you to crossflash build without any issue ...
