[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] circa_:
Hey Modpunk! Thanks for replying. I just wanted to let you know I'm really new to all this. To be honest, I don't know what I'm doing. I been trying to piece together this puzzle. Originally I said there was a bootloop, so i wanted to provide all the steps I took to get there. But I ran into another issue where I can't decrypt the filesystem in TWRP after backing up.

Part 1: Downloaded TWRP, VBMETA, and Lineage OS Rom Files (https://xdaforums.com/galaxy-s10/sa...rom-lineageos-17-1-beta0-s10e-update-t4076585) (https://xdaforums.com/galaxy-s10/samsung-galaxy-s10--s10--s10-5g-cross-device-development-exynos/recovery-twrp-3-3-1-0-s10e-update-2020-t4067765}

unpacked twrp-3.3.1-0-android-10.0-beyond1lte-3

patched twrp-3.3.1-0-android-10.0-beyond1lte-3 with Magisk on phone

moved magisk_patched.img to computer

Renamed magisk_patched.img to recovery.img

Renamed vbmeta_disabled to vbmeta.img

Added twrp and vbmeta images to 7Zip archive as tar

renamed new tar file to recovery.tar

Part 2:

moved Lineage OS Rom files and gapps to SD card.

Turned off phone

Held volume down + bixby button

Connected USB cable

Launched Odin 3.14.4 as administrator

Loaded recovery.tar in AP slot

Under options tab deselected Auto Reboot

Receive Pass!

Part 3:

Reboot device holding volume down and power button for 7 seconds

When the screen turns off immediately press VolumeUp, Bixby and Power), and keep holding it, until the secondary warning appears (The one with warning about unlocked bootloader), then release Bixby and Power, but keep holding volume up, until the TWRP logo is seen.

Part 4:

setup fingerprint (for some reason I cant get fingerprint to work - enrollement was not completed.)

install magisk manager > reboot

boot LOS > enter pin

enable android debugging

poweroff

Part 5:

remove vbmeta.img from recovery.tar (only TWRP being flashed)

Held volume down + bixby button

Connected USB cable

Launched Odin 3.14.4 as administrator

Loaded recovery.tar in AP slot

Under options tab deselected Auto Reboot

Part 6.

Boot into TWRP

enter pasword (decrypt)

swipe to allow modifications

backup > SD card > boot + data > swipe to backup (not really sure what to select to backup.. is there a combination that will allow me to restore TWRP with out reinstalling the rom?)

reboot to system

boot to LOS > enter PIN > try again in 86400 seconds

cmd / adb logcat > logcat1.txt (log attached)

power off

boot into TWRP

enter password > password failed.

My end goal is to have your version of LOS running as my daily driver. I want to make sure I can backup and restore so I can switch between ROMs. Right now it dosen't seem like fingerprint unlocking is working for me. How does the Vbmeta and boot (magisk_boot_beyond2_ctd1_beta2.img) image work?
