Prepare ODIN with the files CL + BL.
This worked for me this wait, my phone was like yours...
I Cannot turn phone off too.
There's a trick...
All the time you enter in Download mode, and hit Start in Odin, the Odin says "FAIL" and the phone automatic reboot.
The trick is..
When in "Download mode" Start and at the same time press and hold "Vol Down + Bixby + Power".
Odin says FAIL and it will restart the phone automatic.
Press faster and hold "Vol Down + Bixby + Power" to go again to "Download mode".
Press Start in Odin and be prepared to press and hold at the same time "Vol UP + Bixby + Power".
Odin will start to transfer the files... and after that the phone reboot again faster, just press and hold one more time and faster "Vol UP + Bixby + Power".
TWRP will start !
