If the system cannot be restarted, you must reinstall the system software.
Connect storage media that contains update data of version 4.75 or later, and then press the START and SELECT buttons at the same time.

so i tried many different PUPs and even downgrader PUPs and nothing worked(i dont want to use an OFW PUP cause i dont wanna lose my cfw and cant afford another cfw) i tried doing it many times and on "preparing to update, it goes fast then when it hits 89% it starts of very slow then when it hits 98% it stays stuck forever. please any help will be very appreciated guys thank you

im not 100% but freezing on recovery mode could be a sign of a corrupt hdd..

You could try to reformat it with option "restore ps3 system"
this will wipe everything games, saves, homebrew, etc...

if it won't let you reformat, try another known working one

will this also format my hdd?nvm i clicked it and it went back to the 4.75 or later screen...

still no go?
swap out the harddrive. you got another one to put in and try

Yup worked, but it's a 80gb hard drive and my old one was 320gb

great
a working 80gb is better than a non working 320gb any day of the week haha
