SF2MJ Posted December 13, 2008 Share Posted December 13, 2008 Can you install custom firmware on a 3.73 psp? A friend of mine has one with the official firmware of 3.73.I just want to modify it so that it can play iso files.Is there an easy installer for his psp?

loveyou Posted April 18, 2009 Share Posted April 18, 2009 Well as far as my knolage goes there is no downgrader for this Fw. You need something called pandora's battery. and that with in it's self is hard to explain to someone how to make and use properly. The homebrew/CFW scene has died down alot so theres not to much to do because once pandora came out for the fats/slims all the coders just stoped with the downgraders.The only downgrade i can remember is the lumines downgrade for 3.50.There is a HEN(homebrew enabler) comming out for the new psp bright. So basicly to summerise what i said because i kept going in circles. Unless you get pandora's there is no downgrade method. Link to comment Share on other sites More sharing options...
