I had converted my PS3 to dex with the linux/multiman tutorial for SLIM models (NOR).
It all worked fine, till I decided to go back to CEX becouse of the new CFW for ps3...
As you can guess, I turned off my ps3..... >.<
I followed the tutorial about how to unbrick your PS3, but after I prepared my PS3 using power-eject with my PSP as jailbreak device, I got stuck.
Once I use the PSP, i get the normal stuff in my display about changing some hex values. Then, when the ps3 turned of automaticly, i putted in my USB stick with the Lv2diag.self and the PS3UPDAT.PUP on the root of it.
At this point, it normally installs the firmware from your USB, but here it doesn't....
It only gives the 8 beeps, then shutsdown and is still bricked....
Could ANYBODY help me ? I can make pictures, vids etc. But please help me out. :s
