Use TWRP to backups data, boot, dtbo, and super while you're still running OOS. Then, when you've finished with custom rom, restore OOS using TWRP (follow instructions in OP) and make sure you restore super to the same slot you were on when you backed it up.
if you are rooted with magisk you can keep twrp...I have an OP8T with LOS 18.1 and LOS custom recovery.
I wanted to flash TWRP, but if I try to disable "Update recovery" on my LOS flash settings, it says:
"It is impossible to disable Lineage Recovery updates on this device"
So, in each LOS flash, will I lose TWRP as LOS custom recovery will be flashed?
Another method without EDL/MSM and without backups: https://forum.xda-developers.com/t/...epo-of-oxygen-os-builds.4193183/post-85466569
Interesting question. Vendor on this phone is a virtual partition (it lives inside the super partition). So it is flashed when you flash a rom. But, because it isn't a physical partition you can't back it up or flash it on it's own.
Understood. So, it would be possible to build custom roms with prebuilt vendor, as well as roms that would use stock vendor?Interesting question.

Of course I'd happy for someone to prove me wrong.
Not all of them. Some build vendor, some don't, instead they are using stock vendor. So, the first time, users flash latest stock to both slots, then they install a custom rom, which doesn't touch vendor. Oneplus 6/6t are a good example.
A good place to learn about this is to read the AOSP documentation (on a PC or in desktop mode on a phone) about OTAs and A/B devices: https://source.android.com/devices/tech/otaCan someone please give me a quick short lesson about slots? What slot should I be flashing TWRP, custom roms and magisk, and GAPPS? There are two slots A/B from what I understand. My current knowledge about this slot seems like a recipe for brick.
This is my first modern smarphone. All my phones previous only need to flast twrp then flash custom rom. Now, phones have slot a and b to chose and if you chose the wrong slot, bam. bye bye phone.
New OOS release. I'm running OOS with TWRP and Radioactive kernel and I was just wondering becouse TWRP cant handle OOS flashing. But somebody wrote here about using local upgrade in OOS settings.
OK I continue my monolog.
If someone is intressted I created a black Themed TWRP Version (Themed by @acuicultor and @Morphine1) for the Oneplus 8t.
This TWRP is the same one as the one here in the OP just with the black Theme applied to it.
I put the IMG file for that here which can just be booted with fastboot boot twrp_black-3.5.2_11-0-kebab.img
As of now I only put the black themed .IMG file there but will provide a black themed installer.zip as well later on.
