How can I downgrade my psp ver. 3.50 to 1.50?

Is it possible to downgrade psp 3.71 to 1.5 w\o another psp??

  • i have a psp with 3.71 firmware on it ( i bought it from a buddy that way) and i want to downgrade it to firmware 1.50. i googled this and found out about the whole pandora thing but the problem is that i dont have access to another psp...... i have a 2 gig pro duo memory chip and a fully charged battery.... does anyone out there know any kind of way for me to downgrade?? please help.......

  • Answer:

    you do not need another psp to make a pandora battery, but you will need to hardmod the original battery, and it will then no longer be used to boot the psp normally. follow my guide (everything can be made on official firmware) http://www.zshare.net/download/5554099c2452a4/ and the pandora battery is the only thing you can use to downgrade any firmware higher then 3.51
