I’m hearing lots of rumours after yesterdays news of flash access (for PSP’s running firmware 2.5/2.6) of a potential downgrader that will revert a PSP back to firmware 1.5.

At the moment, as far as I am aware, there is no such software and nobody should attempt to use software on their PSP. There are several stories doing the rounds of people who have used software they believed to be a downgrader on their PSP only to find the device has become bricked (ie broken/dead/not working anymore).

Please do not attempt to use any software that is intended to downgrade your PSP running firmware 2.5/2.6 until there is an official announcement from a reputable source that such software exists and will not harm your PSP.

Bear in mind that the time to create a downgrader and fully test it will take longer than 24 hours from the time the exploit was announced. Also consider that the people who have spent a lot of time developing software for the PSP are still unsure if the exploit is going to allow the firmware to be rewritten. The likelyhood is that the access will not be sufficient to change the firmware version.
