problem booting up w/ my backups
 

i have purchased a m2pro from precisionmods. it's been working fine until today. i've used ritek dvd blanks w/ recordnowmax on my pioneer a05. i've read the boot instructions that was mailed w/ my console. but now my backups are not booting up. can you help me? i also was using memorex cd-r's. any solution?

If what you are saying is that when you received the console the chip worked fine then all of a sudden stopped working. This would imply that something has come loose.

could it be possible to assume that maybe i need to clean my laser?

That could help, but like Headly said, something probably came loose.

okay, i just tried to load up w/ original(s). but no success. damn!!! what do y'all think?

Something had to have some loose. Open it up and have a look.

I still think that something came loose. It is probably bridging two points now and interfering with booting all games. This is what happens sometimes when BIOS are bridged.

thanks, but is there a site that gives instuctions on how to open up a version 4 ps2?

Or just contact the people who modded your system. Im sure they would help u out. If they dont then try the other method the other guys said.
