Want to downgrade your PSP?

If you want to downgrade your PSP, but not sure which downgrader to use, then this is the guide for you. No more searching for the tutorial either on how to downgrade.
Here I will link to all the downgraders available, so you can find the correct downgrader.

Any firmware version PSP
* This will work on any firmware version and will also unbrick your PSP. To do it though, you will need another homebrew enabled PSP. Use Pandora's Battery ([Only registered users can see links. ] [Only registered users can see links. ])to downgrade/unbrick
---------------------------------------------------------------------

You are now free to enjoy the world of homebrew. To play isos, you can use devhook, which emulates the Sony firmware. Or, you can upgrade to custom firmware, which, gives you all the advantages of 1.50, and the official Sony firmware, and more, such as the ability to run your own PSX games. If you would like to upgrade to custom firmware, please use this [Only registered users can see links. ].
