Lately, I have noticed many threads created within the Hacks forum which do not belong here. Everyone is excited but we must maintain order in here despite that.
These threads will be moved to the appropriate locations without redirect, and possibly without warning, in order to keep this section free from unnecessary clutter.
If you need help, check out the PSP Hacks and Homebrew Forum first and if your question hasn't been asked, post within there.
The fact that PSP Hacks has many viewers isn't a valid reason to post here and will not guarantee you a fast or worthwhile response.
P.S. It should be noted that the moderation staff is on high alert for posts which break the various Forum Policies we have in place. Many people have found themselves banned for spamming.. please review our policies before you find yourself in this group of temporarily banned users.
3.51 Downgrade Info
There is no current exploit to allow a downgrader for firmware 3.51. This includes the option to allow un-signed code (Homebrew) to run on 3.51.3) Do not ask:
When an emulator, game or hack will be made or released, for a special emulator or game to be written/ported for you, when a downgrader will work on X.XX. Do not ask when homebrew will be available to X.XX users or for help with anything that is covered in the FAQ's or can be easily found by searching the forums and reading the stickied threads.
If a option does come about to downgrade the PSP Hacks section will be buzzing with details.
Edit: - The New Pnadora Battery gives the option for a user to downgrade any PSP Firmware even 3.51 + Pandora Battery Discussion
