Hi!
I get this error. Cant boot into recovery.
Is it because the S20 had OneUI5 installed?
Think i did every step right before this.

Could it be easier to install LineageOS.
Or, do i have to roll back to OneUI4 or something, before installing custom OS?

Doing it for the first time :)

Have you flashed with TWRP a Vbmeta disabler?
I got the same error without that file the first time that I tried to put a custom Rom on my S20
For the lineage os the last version is 19.1, you have to downgrade to OneUi 4 (Android 12), and the Lineage OS have a old security upgrade (Download an antivirus)
You can flash a lineageos 20 gsi but it has some bugs

Samsung Galaxy S20 / S20+ / S20 Ultra
0. Get an up-to-date fastboot on your computer (fastboot —version should give version >= 29)
1. Get vbmeta.img from https://dl.google.com/developers/android/qt/images/gsi/vbmeta.img
2. Get A/B GSI (I'm guessing you need ARM64), don't forget to uncompress it
3. From running Android, do adb reboot bootloader
4. fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
5. fastboot reboot fastboot
6. fastboot flash system system-xxxx.img
6bis. If fastboot tells you there isn't enough place, do fastboot delete-logical-partition product, fastboot delete-logical-partition product_a, fastboot delete-logical-partition product_b and run the fastboot flash command again
7. On your phone, the screen should have a button "go back to recovery", select it, then select "factory reset / wipe data"
8. Reboot and enjoy

I followed this guide to the point. But since her download file from google is removed i had to try to find the right files by myself.
I will try to downgrade it to OneUI4 to see if that can fix things. I also have a Samsung A70 i can try instead, if that is easier to mod.
