(adsbygoogle = window.adsbygoogle || []).push({}); So yeah, if I install the CFW on my PS3, can I then download the original 3.55 firmware and restore that, removing the CFW?

Yes just download the original 3.55 from Sony's website. Then do the usual setup on your usb, PS3>UPDATE>PSUPDAT.PUP
Then you will be back on original firmware and will be still able to use FTP

I can still use ftp?!?! Yay! :d

Could someone link me to the 3.55 original firmware? Can't find it
