SamyGO is not compatible with T-CRLPEUWC because no one could send me firmware of their TV's EXE partition.
SamyGO Firmware Patcher script cannot modify this devices firmware (FW from samsung has no exe.img in it, it's only 3,5 fw) and No application work within Content Library on B550.
This why we don't support this devices. I didn't know if Debug Menu works.
What ever your firmware is, if you have shell access, than you can revert your firmware (via flashing by hand) to older version if you have the older version of FW at hand.
