C5 errors

I installed a hyperflash fix to my c5 corvette. That is fixed, but I but now I get codes for reduced engine power, service traction control, service active handling, and my backup camera has no video. The battery died during installation (only 6 months old), so I recharged it and no fix. I tried disconnecting the battery for 30 minutes, but no improvement. Has anyone else had this problem with the hyperflash? I'm asking before I take the whole console apart again and remove the hyperflash fix and put incandescent bulbs back in (hoping that would fix the issue).
