Dear colleagues,
Please help with following case.
I have WS-C3560CX-12PC-S switch which doesn't allow configuration over console CLI - no command prompt showing. Same time console hardware is fully working, as I'm able to send commands when in bootloader mode.
After boot process i see message "Press RETURN to get started!" but no reaction to any input. If I connect or disconnect ethernet cables to switch console continue to show log output, so it doesn't hang.
Press RETURN to get started!

I've tried to boot to bootloader (MODE button long press) and do xmodem reflashing new FW after full flash format. This operation succeeded (confirming that console is working), but after reboot again no CLI prompt.
Below are my boot env variables. Maybe it could be helpful somehow:
