I've installed the DMS4 EZI Lite perfectly by the install guide, infact after I was unable to boot the flash disc the first time I took the system apart again, removed the mod chip, checked all contacts and reinstalled same problem. If I hold the square button it disables, but from what I've read here that doesn't mean much really, but I'm 99% sure that I have it hooked up correctly. Is there any trick that I'm missing I'm using the file from teamtoxic's website burning with Nero 7 in 4x mode, it could be my cd media I'm using imation cd-r discs. Any other ideas on how to flash this thing? I don't have anyway to do the MC exploit to do it that way as I have no hdd or network cable, all I want the chip for is so I can play custom music on Guitar Hero 2. Please any help I would really love, hell I'll even donate to the person that helps me get this damned thing working right.
