(adsbygoogle = window.adsbygoogle || []).push({}); Hello. I recently bought a new PS3 hard drive (500gb) for my ps3. Then I put the 3.55 updat.pup in PS3/UPDATE/PS3UPDAT.PUP, but when I go to recovery mode and plug in my usb containing the update with nothing BUT the update it says it cannot find the update data. Any fix?

It's not as simple as putting a 3.55 update file. You need to actually downgrade it using a Progskeet, Teensy, or E3 Flasher, depending on the model.

For your information I actually did that on my older HDD. Some other forum tells me that I cannot downgrade because my last firmware (rebug 4.7 is stored a little on the NAND so I can't downgrade, but if I go to 3.55 ofw on my old hdd and then on my new hdd will it work?

Yup, or you can put the same CFW on the new hard drive and go from there.

you gotta install same firmware that was on it before hdd change or you can install the downgrader
but your best off just installing same cfw u had on it.

Are you running OFW? Also, what FirmWare are you on?

it needs to be update 4.78 or higher. it will not allow anything lower

if it hasnt been jailbroken, you cant install a cfw, if you are looking to downgrade, you will need to understand if your system is supported to be downgraded, this can be found through "ps3 downgrade compatibility"
