So, making a long story short... I had this old laptop laying around with a 500GB HDD, while my PS3 HDD was around 200GB... I switched the hard drives around.... Now let's talk about 4.83 if you accidently upgraded... - In a way would it be technically possible to take out the HDD of your PS3, put it in a laptop - Then start the laptop with a bootable HIREN Boot CD USB pen drive... - Reformat the PS3 HDD in the laptop with the tools in HIREN boot CD... - Then make a USB Pendrive with x:\PS3\UPDATE\PS3UPDAT.PUP - Put the hard drive back in the PS3, boot it up, and it says no firmware found it installs the 4.82 firmware again? I know it seems kinda a hassle, you loose everything on the HDD... but with the 4.83 update you lost it anyway... But would it do the trick reverting back this way to 4.82?
