i have now a slim ps3 cech-2004a 120gb. it has 3.56v1 and i have run the version check on it and the minimum is 2.70.
so, can i forward install the JFW MA 3.56 on it? or install via recovery? is there any risk?
as far as i know JFW 3.56 doesnt actually install on 3.56 you need to downgrade to 3.55, so you would need a e3 flasher or a progskeet. if the 3.56 pkg private keys are on wiki then it would be possible to install a 3.56 custom firmware but don't know..
