To anybody who can help. I followed Brenza's tutorial and everything seemed to work fine but i cant get back to OFW 3.55. I have a launch phat ps3 NAND that was never updated past 3.55. I installed Kmeaw originally then switched to DEX to play RE6 and now I really want to go back to CEX 4.21 rebug.
I have followed this tutorial word for word and tried everything. I didn't have my original flash dump so I created one from the DEX dump with c2d and flashed with multiman just as it says to do. Multiman said no errors and said it flashed eid0 and 192 bytes or something to that nature. I ran the reboot pkg and then the QA package, got 3 beeps.
I restarted my ps3 via xmb and have 3.55 ofw on usb drive. I go into recovery mode and select option 6 and it says no applicable data found. Its like multiman is not flashing the whole 239mb to the flash. Could that be it or am I missing something totally. I will not be able to try anymore until tomorrow afternoon after work but any help is greatly appreciated. I just want to get away from Dex and be done with it. Thanks again to anybody who can help.
After lots of research last night I figured out my problemo! In c2d I was ending the command c2d.exe eid0 flashDEX.bin flashCEX.bin 82 instead of 84. 82 is debug console Target ID. I did the whole process again and am now back on Kmeaw. Yes Sir!!!!
