[GUIDE] unbricking seriously bricked oneplus devices

This method is actually dangerous. Do not try this unless you have a good reason to do so
This method erases IMEI. Backup EFS with official or enhanced TWRP. Do not use any other TWRP as these might not backup EFS correctly and you will lose IMEI
Only use this as a last resort if everything else fails to revive your device.

First open the download tool. I will assume you at least know how to use it in the default upgrade mode

Press the verify button. The unbrick tool will freeze for a bit. Wait until it shows something like this:

After that close the verification window. An SMT download mode option will be unlocked

Yes, red signifies danger. Don't ask

Now press start

You'll see this box

The password is te123
Warnings: type the password exactly as it is. Do not make typos
Select your exact storage size

If you do not do this correctly you'll worsen the situation

Hit ok and the download will start

When the download completes you'll see this screen:

Disconnect your phone. Now exit the program
You might see this message but if it says download complete like in the screenshot above it is safe to press yes

Your device will not auto reboot like it did in the standard download mode. You'll have to press and hold the power button to force a reboot

Boot oxygenos fully and immediately use TWRP to restore your EFS backup

If you get an NV backup warning first restore EFS and then follow the steps given here https://forums.oneplus.com/threads/nv-backup-warning.474643/

I had a person who badly messed up his bootloader. The unbrick tool in upgrade mode didn't help. SMT fixed the issue and thankfully he had an EFS backup so the device was back to normal
