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):


IN11AA tools (international firmware):


IN11DA tools (indian firmware):


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 Android 11 MSMs and up Windows 7 users may need to launch MsmDownloadTool V4.0_Win7.exe instead, but it hasn't been tested


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..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) 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?

What is the password of the mirror?

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.

Hi,

I bought a Chinese Version, tried to install international rom, didn't know oneplus started locking their phones, and I believe I bricked it.
Any version to unbrick the Chinese version?

Thank you

You should be able to use any of the tools present in the OP but I would advise that you backup your /persist partition before (in main window of tool, press F8, tick "persist", input "oneplus" as password, press "ok" and click on the readback button).
Partition will be at the root of your system drive.

When I click to launch MsmDownloadTool V4.0.exe, nothing happens, just a small window comes up stating "program has been started but nothing happens...

EDIT: I got it working, driver needed restart.

I cannot enter EDL mode. I can reboot between system, recovery and bootloader but cannot enter EDL mode. I help vol+ and - for a while several times, nothing.

Another EDIT: I got into EDL via adb, it's doing it's thing now.

Hi everyone, similar to the previous threads for
OP3, IN11BA tools (european firmware):[/B]
ANDROID 10:

I have not been able to determine the different 8 Pro devices, and since you seem to be on top of everything, I would like to ask a question.

OnePlus is calling the 8 Pro they are selling here a "US" version, and i don't see anything like that here or elsewhere. The overseas versions are "Global" which I would guess is the same as your "international" above. Since I am looking at a possible Global version, I am not sure if it will have the same frequencies as the OnePlus one.

If you can help - thanks. After I get an 8, I will be using your tool and firmware to take My 7 McLaren 5G back to stock.

Can you explain how?
I am also stuck between fastboot and recovery, can't seem to enter EDL
any guide how to do it?

Pressing Vol up + Vol down + power gets me to fastboot mode not EDL

Thanks.

Are you trying to use the unbrick tool? Also I think EDL is just vol+ and vol-, no power button for that. It did not work for me with buttons, I got into EDL via adb, adb fastboot EDL, I believe.

I would like to thank everyone for trying to help me out. It was a mentally exhausting day, I must have wiped my phone at least 15 times. I'm giving it a break for now, will get back into it over the weekend.
