i have been lucky enough to get hold of a launch ps3 60gb on fw 3.41. i am about to install an infectus 2. i have some questions
1. if i make a nand backup of fw 3.41 and update to 3.55 is it possible to just flash 3.41 whenever i want to downgrade? or is it more involved?
2. same as above, but from 3.55 > 4.00 then 4.00 > 3.55/3.41
i am a bit confused with all the files needed like 'factory/service mode' not to sure if i would need this as i am using direct nand flashes.
hopefully somebody can help me, +rep for anybody who can. (i will also be doing a video of my infectus install > could possibly help ppl learn how to solder to test points etc)
