1st error is apparently a hard drive issue

2nd I'm not finding much that's definitive. Only person I saw who said they solved it said they were trying to install CEX over DEX. I assume the drx means D-REX, but can't find any reference to that firmware to be sure.
Over my head at this point. Hopefully someone more knowledgeable can swoop in and help you. My advice would be just replace the ribbon cable. NoBD isn't generally desirable anyways as it has some limitations.
I just remembered I went super retard on this one and forgot I actually tired super glue on the BD peice that holds the ribbon cable and I tried gently removing the peice and ended up destroying the "teeth" connectors on the actual motherboard now.
Looks like either I get nobd cfw working or just junk it at this point since it needs a new connector soldered onto the motherboard at this point
