(adsbygoogle = window.adsbygoogle || []).push({}); i recently found a ceche01 ps3 with 3.55 ofw on it and i know you can jailbreak a ps3 on 3.55 ofw. what is the best ps3updat.pup file should i download? which pgk files? sorry kinda new to this, any help would be appreciated.

First a 3.55 jailbreak and then upgrade to higher version of that like rebug, roggero blablabla

Look on rebug.me

You should take a 3.55 version which is already a custom firmware. Like the 3-55 from GeoHot or something else. You should't install a higher CustomFirmware at first then 3.55
