I managed to brick my phone (OnePlus Nord CE 5G) to the point where I can only get into fastboot and fastbootd. I was using oxygen 12 previously so I believe flashing 11 is not possible.
I was able to extract all the images from the latest oxygen 12 image found here for my phone using payload_dumper, but I can't figure out where to flash all the images to. I've googled around a fair bit but I can't find any specific instructions for this device/update.
My best guess is the script below. All the steps are successfull but I'm still left with an unbootable device.
Any help would be highly appreciated.
#!/bin/env bash
# This script assumes all .img files are in a folder called images
# Wipe entire device
fastboot -w
# Images that should be flashed in bootloader mode
# (Said someone on the internet)
