I accidentally upgrde my psp, all the game inside memory all gone, how to downgrade it back


Depending on the PSP Model 1000-2000 you can downgrade your PSP using Custom firmware by forming a MMS using RainsUltralite and a Pandora's battery. Custom firmware equivalent to the official firmware can be determined by the games played. Most recent games require updated firmware. This site should help you with all the software necessary to downgrade or modify your PSP. http://pspslimhacks.com/rains-ultralite-mms-maker-for-500-m33-4/

How do i downgrade psp 3000 running ofw 6.31....help me please


Unfortunately there is nothing you can do at present to downgrade a PSP 3000 that has firmware above 5.03. Pandora battery does not work and neither does chickhen, until someone works out a way of enabling custom firmware on a PSP 3000 above 5.03 I am afraid you are stuck to official firmware.

Hope this helps and thank you for using FixYa

How can i downgrade my psp version 6.30 ofw to 5.50 gen-d3.without using any pandora battery


I am afraid this is not possible, if it is a PSP 1000 or 2000 you would need a pandora battery. However if it is a PSP 3000 upwards there is no way to downgrade the firmware at all. Anything above firmware 5.03 is not possible to downgrade on a PSP 3000.

Hope this helps

Psp 6.10 downgrade


You can downgrade your psp from 6.10 with a service or pandora battery. This will let you back up games you already own and run them from the memory stick. You can create a pandora battery and the 'magic' memory stick from any psp already running custom firmware. Tutorials are all over the net and sites like youtube.

Downgrade PSP from 3.80


It's impossible to downgrade your PSP from it's current version. I'm not quite sure why you'd want to downgrade, but maybe you should upgrade (If a version is available) again and see if you like that version better. ^-^
