BR 9.3 with canary (25205) and patched twrp 9.7.0_9.0 is the last smooth working config without any problems.
Did you get BL and CP from Sam, flashed in Odin and afterwards BR 9.4 in twrp? Which version of magisk and twrp are working for you?
after flashing stock hvj5 fw with odin and latest twrp, you have to go to twrp and flash br94I now have download the latest HVJ5 firmware. I will install this with ODIN.
After that U install magisk and flash the newest TWRP. The TWRP I will flash with odin, without reboot and after that go into recvovery. But the latest step does not work, it gives a fault and then I need to go back to stuck.
What could I do wrong?
Honestly I keep reading your OP. I can't find any solution in my case.
Oh yeah. I clearly understand your answer.
