Device softbricking after flashing vbmeta - OnePlus 8 Questions & Answers

Hello, i have a OnePlus 8 5G UW (IN2019/2020) and i wanted to flash a gsi on it, however, after disabling verity and verification using vbmeta and vbmeta_system, and a reboot the entire system/vendor/product partitions goes missing and i cannot flash to it using fastboot.
attempting to boot system will result in crashdump saying attempted to kill init
i'm also unable to format it.
I'm aware i have to use msmtool to fix but how does one avoid this mess entirely?

***After further investigation, it looks like TWRP on a11 is bugged and causes this to happen (images were flashed with fastbootd from twrp)
that's my best guess.

I brought the phone used and some dude installed oxygenOS on this using whatever recovery that is and I want to remove that and install TWRP and install RR 7.1 because this recovery thingo won't let me install anything it just comes up with constant failures. I have searched but I have no idea what I am looking for I just came across that image trying to find out how to remove this recovery but I don't want to brick my phone so if someone can help me out and install TWRP over this that would help a tonne.
fixed the problem by not rebooting via fastboot after installing TWRP

Flash stock with Odin
Hello, I have a question: why are you trying to flash a custom ROM using Odin? It is usually done with TWRP...
And if you want to do you need, you have to again reboot into Odin (downloading) mode and to flash a stock ROM for your device

Hello Guys I am going to sum this up in as little words as I can to make it easy to understand to you all.
I rooted my Edge 2021 with magisk but after a while I got rid of magisk and unrooted, After some time I relocked my boot loader, I locked the boot loader successfully but the phones /system file got corrupted, the phone is now stuck on fastboot and any other action that I do only brings me back to the fastboot page.
I have tried fixing with my PC but flashing is locked so I can’t flash anything and I can’t unblock the boot loader because the OEM option is now off with no way to turn on and the Motorola recovery tool doesn’t work or help me in any way.
Is there any way to fix the phone? Doesn’t matter if I loose my data.

Question Error verifying vbmeta image: invalid vbmeta header (6) VBMETA A525FXXU6DWE3, 66013423R

So basically I tried to download twrp on my Samsung Galaxy A52, while doing the odin process (as you can tell im very knowledgeable about this subject) this error popped up in the downloading screen. Now whenever I try to use the volume down + power key it puts me in a black screen and then puts me back into the same screen with the same error. I would love if anyone has any input on this subject as this is my only phone! Please reply as soon as possible as I am very short on time. Thank you!
