I had problems using current versions of TWRP.I figured out the problem, the fix was re-partitioning via odin. But now I couldn't flash TWRP, if I did so the first problem would appear again. Now I have stock everything, I would like to install TWRP again but with multiple failures I quit, I'll comeback to it when I got bored of stock. Do you have any suggestions?
Reverting to TWRP 3.3.1-1 solved my S8 G950F flashing issues.
