(adsbygoogle = window.adsbygoogle || []).push({}); I have been out of this part of the forum for a while, and now i'm confused, i have the oldest ps3, the first one ( SD cards, 4 USB, it can run ps2 games.. ) And i had it jailbroken, but my brother, updated it to 3.70, can i go back to 3.55?Or it's a newest jailbreak out? Thank you all, btw, sorry for my english :S

yes you need a hardware flasher to downgrade to 3.55 your ps3 model is perfectly compatible with any hardware flasher.

Thank you mate / No way without a flasher?

There is a 4.11 CFW, but I don't know if you can install it from a FW between 3.55 and 4.11 :|
Do some research on goolge or something :ca: (about the 4.11 CFW)
