(adsbygoogle = window.adsbygoogle || []).push({}); I've searched for it and from what I've found out is that you can't downgrade firmware. You can mess with firmware with offline. I have 3.42 firmware and that's the problem. This firmware prevents the mod chip from working. Is it possible to downgrade firmware and still jailbreak my ps3 and start doing hacks for ps3?

Not yet. Mayb in the future

no ur just gonna have to wait until they release the jailbreak on 3.42
