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/


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?

My phone shows up as IN2019, I don't see where it would be QDLOADER 9008 or QHUSB_BULK. I can't get into EDL. What should I try next? I tried fastboo and ABD nothing gets it into edl

As said in OP, QDLOADER and QHUSB_BULK mentions are meant to show in device manager. Refer to OP to get into Qualcomm EDL mode: use hardware buttons once device is off or reboot to EDL by adb.

What are the odds of a MSM tool for A11 once VZW releases the update?

Do you have the file for op8 in2019 10.5.4? After I did the last upgrade I couldn't connect to the network anymore so want to roll back. I am using an unlocked version on the Verizon op8 unlocked in Canada.

Unfortunately I don't, this is the only version I've been able to obtain.
I however believe that if you get your bootloader unlocked after reaching out to @Whoareyou (reference https://forum.xda-developers.com/t/oneplus8-vzw-bootloader-is-not-unlockable.4091933/post-83769667 ) you should be able to switch of current slot by using fastboot --set-active=other and therefore go back to 10.5.4
