Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T and regular OP7TPRO here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus 7T Pro 5G McLaren bought from T-Mobile.
They can also be used to rollback your phone to a previous release of OOS if for some reason you want to go back to an older firmware :)

It will only work with 5G T-Mobile variant HD1925

You can download the following versions:

ANDROID 10:


Instructions:

Launch MsmDownloadTool V4.0.exe.

Specific to 10.0.27 and up

On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.


Click on Target button and select T-MO if it hasn't been automatically.
Power your device off.
Maintain volume up and volume down keys to get into Qualcomm EDL mode.
Plug your device to your computer using stock OnePlus cable.
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds.
Enjoy your brand new device.

FAQ:

Will this fix OTAs I couldn't receive after unlocking bootloader?

Yes. Mind it will however wipe all of your internal storage and relock bootloader automatically (but you shouldn't have to reapply for an unlock token if your bootloader was unlocked previously).

Does this work on Mac or on Linux?

Unfortunately no, tool is Windows only. You should need at least Windows 7.

Why is my antivirus freaking out when unzipping the archive or running the tool?

In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.

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..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-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 above.

MSM tool is stuck on "Sahara communication failed"

Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.

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.

How can I fix "SMT config not found" error?

Excuse my lack of knowledge on the subject. Is this what we've been waiting for? I'm guessing no or very little experimenting was being done because nobody wanted to destroy their phone. But if I understanding correctly this will work like the one for the 6T only difference is we can't flash a global firmware (for the moment) if you royally f**k up this will save you. With this tool it should make experimenting with the device a lot less of an issue?

There's a button that has them all listed. There's three versions.

More or less, but there simply is no global firmware for us to
convert to for this device (they could create one, I suppose).
This tool will fix just about any sort of brick we may encounter
during normal experimentation.

I guessing there's a strong possibility of a global conversion hindering 5G?

I'm just glad there's a tool available to people that want to modify their phones and don't end up with a 900$ paperweight in the event something goes wrong.

You sir are a lifesaver! I was having too many issues with my phone after some of the tweaks, and was stuck on the .16 software version. Now I'm updated to .19 and ready to break the phone again! :D

What if you connect your phone and it does not even show up as the bulk driver in device manager. I have literally bricked it to the point that only edl mode shows up. Can anyone please show me the light?

While booting up the phone hold I believe volume up and plug it in while doing that it should just remain on a black screen after that open msmtool and see if it's connected if it is then do what you would normally do for msmtool. It took me a couple of tries to get it to recognize with this phone compared to my 6T

So My One Plus One 7t Pro Mclaren edition (TMO) is bricked beyond belief. It only reboots into Fastboot mode. From CMD when ADB devices command is typed in it says no devices found. When I look in device manager when connected it says Android Bootloader Interface it does not show any of the drivers to update. I tried using MSM. My phone does not make a connection. Can anyone offer any assistance to help me get this phone back and working? Or am I just stuck with an expensive paperweight.

As said in the OP, you need to turn your device off and enter in Qualcomm EDL mode.
Maintain power button until your device screen goes off, wait 20 seconds, maintain volume up and down keys, plug your device to your computer using OnePlus original cable and use MSM tool.
