I have a slim ps3 that I bought around 6 years ago, it's a 320gb CECH-2501B. It originally came with 3.4 firmware. I hacked it back then, and kept it on 3.55 for a long time, then, my little brother moved in me for a brief time, and I let him upgrade the firmware so he could play black ops online, I was really busy with work and didn't really care at the time. I have recently became completely disabled, so I figured I would take some time and downgrade the PS3 back to 3.55 with a NOR flasher. I followed a guide entitled "Ultimate Fool Proof Guide: Ps3 Hardware Downgrading" from here:
http://www.ps3hax.net/showthread.php?t=39766 . The guide was pretty straight-forward, I've done my fair share of intricate soldering so I wasn't intimidated. I soldered everything in, and proceeded to dump my NOR. Everything went great, I took several dumps, and verified them against each other, I didn't experience any errors or anything. This is where the problem arose, the guide gets a little murky around the "Validating Dump" section. As far as I could tell, I needed to verify the dump with all the tools, but only patch the dump with one. Some of the tools in the pack were out of date, specifically swizzys ps3dumpchecker, I downloaded the latest version, and checked my dump, all was OK, so I went ahead and patched it. I proceeded to verify a couple of different ways, which all went fine, so I took the patched dump generated by ps3dumpchecker, and flashed it to the console. Unsoldered everything, reassembled everything, and fired up the console. I first got the message that I need to connect a controller via usb, no biggie, connected it and pressed the PS button. Then, much to my dismay, I encountered a different screen, one I had never seen before, it said something to the effect of "the system software cannot be run correctly", and tells me I need to basically reinstall 4.8. Is there something I'm missing here? I thought I had followed everything thoroughly. :questionmark:
