Hi everyone, similar to the previous threads for

OP3, OP3T, OP5, OP5T, OP6, OP6T and OP7, here are the EDL packages (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 7 Pro.

They can also be used to rollback your phone to a previous release of OOS.

GM1910, GM1911, GM1913 and GM1917 models are supported.

Here are the files uploaded on AndroidFileHost ordered by Android version and firmware your device will be restored to:

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..._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.

My device doesn't stay in EDL mode for more than 10 seconds

Some units can have this problem and there isn't a lot of things to do to fix that, except being fast after plugging your phone to your computer.

There is however apparently a "one-off" solution to this problem available at https://xdaforums.com/showpost.php?p=80021106&postcount=21 . I would like to investigate more on that but sadly don't own the device so can't confirm it.

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.
