Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO and T-Mobile OP7TPro 5G here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus 8 Pro.

You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware

You can download the following versions:

IN11BA tools (european firmware):
ANDROID 10:


IN11AA tools (international firmware):
ANDROID 10:


IN11DA tools (indian firmware):
ANDROID 10:


Warning:

It is advised to take backup of /persist partition before crossflashing (eg going from International to Indian build) as fingerprint reader may give an error related to enrollment issue. You can do so by using dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img (you must have root access, which is not something I'm going to explain here) and moving it to your computer/cloud.

Instructions:

Launch MsmDownloadTool V4.0.exe.

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 O2 while using international tool or India while using indian tool or EU when using european tool.
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. (You may let volume keys go once done.)
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds.
Enjoy your brand new device.

FAQ:

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/...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 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.

What is the password of the mirror?

Fixed typo in thread thanks, ironically enough I didn't have it in the title, guess that's what I get for making threads at the hour where people normally sleep in my timezone...

I've installed the global version of Oxygen OS on OP8 Pro but I definitely bricked it because it's stuck on the boot screen. Tried using your software to unbrick but the phone is not showing up at all, even after using the power button + volume up. Also unable to switch the phone off with the power button. Any advice?

As said in the OP, the key combination to get in EDL mode is volume up and down, not power and volume up.

How come your device doesn't turn off? It normally should after maintaining power button for 30 seconds.
