Panasonic DMR-E50 Chk Remote issue?

My Panasonic DMR-E50 keeps displaying Chk Remote, no remote works, tried the original one that came with it, tried capable one and universal control nothing seems to work. Also, tried resetting the main unit back to factory settings by pressing and holding channels up and down which did reset and now my unit is asking me to select lanugage and clock is flashing and can't change any settings due to remote control not working.
