Hey guys, similar to all of @Some_Random_Username's unbrick threads, here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus Nord N200 5G.

Important: This is only for the T-Mobile variant of the N200. This will not work on the factory unlocked variant and may or may not work for the Metro variant.

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

Press and hold the volume up and down buttons to get into Qualcomm EDL mode.

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.

How can I check my device project ID?

Use getprop ro.boot.project_name. This however involve having ADB access or access to OxygenOS to use Termux or whatever terminal emulator you prefer.

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?
