    Hi all,

    I thought I would try flashing CarbonROM onto my 9 Pro, but wasn't aware that it uses an "A/B partition' setup, as nowhere online prior to flashing mentioned this. I came across an error trying to flash TWRP via fastboot and I ended up flashing TWRP straight onto boot_a. Now I am unable to do anything with my device except switch between TWRP recovery and the stock Fastboot screen. I have tried:
    -Wipe/Factory Reset
    -Format between ext2 and ext4
    -Flash stock ROM
    -Flash custom ROM
    -Using the MSM Tool (getting no further than opening the program and it doesn't detect my device)
    -Extracting boot.img from stock firmware download and flashing that
    -Erasing and formatting Boot Partitions
    -ADB pushing .zip and .img files and trying to flash them via TWRP

    The thing holding me back the most is TWRP saying "failed to mount: system root, system ext, product, vendor, odm", as this error comes up after every single action I make via TWRP.

    EDIT: stumbled across this guy who actually did a really good job of explaining a few things. Fixed my issue
