Hacking ps3 system can't launch after hard drive format

[mrissaoussama]

yesterday i got a black screen after i run multiman (not game just the app).so i thought of formatting the hard drive from my pc, but after i opened it and press the PS button, i get a system can't launch correctly error.
i still can get to the safe mode, i thought about updating the cfw, is that correct?
i have a slim ps3 and the error screen says i have to update to 4.75 or higher

Formatting the HDD is a terrible idea. Half the firmware is on the HDD the other half on the NAND/NOR.

You basically need to reinstall the C/FW you were on back to the HDD before you can use it again, however it looks like you were on a higher version that 3.55 (naturally) so good luck with that.... Probably going to need a flasher, but perhaps there are newer techniques?

Head over to PS3HAX and search the forum for answers: much more likely to find a fix, I haven't been into PS3 for a while so I cannot assist more here.

Google around for 999 Downgrade firmwares.
Make sure you read up on how to use them.

Do you have the pup file for the firmware you were on? If so just install it from usb. If it's a slim model the right usb port works best. You can probably download some other cfw pup and use that instead. I've been through this before, sometimes the ps3 was a little fussy about the usb stick but it eventually worked.
Don't try any downgrades or anything like that, make sure you don't have a game in the system and the system is offline (terrible first advice guys)

Just update it to CFW above 4.75 then use the 999 downgrader as stated above.

Why would he downgrade?

Why would he downgrade?

He obviously messed something up. Better to restart then to leave it.
