Trying To Find A Full Software Download To Correctly Flash OnePlus Nord N20 5G (MetroPcs/TMobile)



Before starting this process, my phone had just updated to 11_A07. I got my bootloader code from OnePlus, Even though my phone won't be unlocked for another month or 2. Anyways, I used the code, unlocked the bootloader, and decided I'd try to root it, figured it wouldn't be that complicated.

Starting off, I Flashed an A06 Boot.img to it, as well as The "JulyModemsBackup.zip" acquired from someone else on here, and I ran into the same problem as others on here, I lost all Radios (Service, Wifi, Bluetooth, NFC), even lost Flashlight and other key things. After trying and trying I ended up running into a screen saying something like "the Boot/Recovery image have been destroyed, please repair" so after that speed bump, I found I had to flash another boot.img, and use the fastboot --disable-verity flash vbmeta vbmeta.img trick, it worked, and after trying to fix the radios, I ran into another speed bump of the phone going straight into fastboot and would never actually boot, so I had to keep trying more and more combinations of files and fastboot commands, until ultimately, I got passed that, and back to having no radio.

Now somewhere, I went in a better direction, because this last time I booted it, I had successfully gained back: Wifi, NFC, Flashlight, Bluetooth, and everything else EXCEPT Actual Cell Service. I was even able to use Magisk to patch the boot.img and root my device. So all I need now Is my Cell Service. I will try to find the exact combination of files I used to get this far, so others may be able to gain a little of the phone back as well, I know that it says my phone is on version A06, so it successfully downgraded, at least it thinks so.



But Im hoping someone has the solution, or may find out how to completely fix the cell service issue. It would be perfect to have a COMPLETE Software File with everything needed, rather than multiple files with just few in each, all of which may be for different versions.
So If anyone has a complete file, please post it, or if you have all the files and can make a complete file to share, that would be just as great. I will look and post all the files I've used to get this far as well

i would go ahead and add disable dm-verity and verification switches to vbmeta just to make sure that things have a chance of working with the rest of the partitions that might still be on a different patch.
might actuallly try to backup your originals from the inactive slot if you havent already flashed those

Yeah, besides editing just a few of the syntax errors, I made, I'd say that the only thing he'd need to double=check would be tthe names of the partitions and like you said, to add the disable vbmeta syntax line to his clusterfuck of a list I made..
