Hi everyone, six months after device release and similar to the previous threads for

OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8, T-Mobile OP8, OP8Pro, regular OP8T and T-Mobile OP8T here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 8 bought from Verizon.

It will only work with Verizon variant IN2019

Be aware this will change your warranty date in About Phone -> Status to "None". This is not something I can do anything for.

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:

ANDROID 10:

OOS 10.5.5

Mirror for first and last MSMs: https://onepluscommunityserver.com/

ANDROID 11:

OOS 11.0

Mirror for first and last MSMs: https://onepluscommunityserver.com/

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 Verizon.

Press Start button so that it waits for your device to be connected

Power off your device

Maintain volume up and down buttons to get into Qualcomm EDL mode.

Plug your device to your computer.

Should you not manage to do that and have adb access, you can use adb reboot edl instead

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

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.

If you can't get into EDL mode by hardware keys, you may use adb reboot edl (will require your phone to still have ADB access)

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?
