OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G and OP8Pro here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus 8.

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

ANDROID 10:

• OOS 10.5.1

IN21AA tools (international firmware):
ANDROID 10:

• OOS 10.5.3

IN21DA tools (indian firmware):
ANDROID 10:

• OOS 10.5.3

Warning:
As this happened on OnePlus 8 Pro, 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

• Launch MsmDownloadTool V4.0.exe.

• On the login prompt select "Other" in the dropdown menu and click on Next.

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/msdownload/update/driver/drvs/2017/03/fe241eb3-d71f-4f86-9143-c6935c203e12_fba473728483260906ba044af3c063e309e6259d.cab (source https://redirect.viglink.com/?format=go&jsonp=vglnk_158747553472520&key=f0a7f91912ae2b52e0700f73990eb321&libId=k99x9nuk01000n4o000DAmx3m2mgc&loc=https%3A%2F%2Fforum.xda-developers.com%2Foneplus-8%2Fhow-to%2Fop8-unbrick-tool-to-restore-device-to-t4085877%2F&v=1&opt=true&out=https%3A%2F%2Fwww.catalog.update.microsoft.com%2FScopedViewInline.aspx%3Fupdateid%3D8ee52ba0-bdef-4009-88cf-335a678dd67a&ref=https%3A%2F%2Fxda-developers.com%2F&title=%5BOP8%5D%5BOOS%2021AA%2FBA%2FDA%5D%20Unbrick%20tool%20to%20restor%E2%80%A6%20%7C%20OnePlus%208&txt=https%3A%2F%2Fwww.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.
