[Q] Why I cannot get TWRP?

Gents,
funny question.

I just installed by Odin the very last firmware (COI1) with custom image from here, and
looks like it is locked and now I stuck with the stock ROM...
No chance to put back TWRP...

Before everything was fine.

I tried bootloader from this post, no luck.

Any advice how to get TWRP back or just how to revert to custom image?..
