5.00 M33-6 - Upgrade Your Psp With custom Firmware to the newest Version

Your Psp runs a unavoidable software called firmware. If you have a Psp that runs valid firmware then you might want to reconsider downgrading. Population who have downgraded their Psp to firmware 1.5 have upgraded their Psp again with institution firmware which allows you to run home brew on your Psp and run games from your memory stick.

If you have already downgraded your Psp then you are aware of the fact that institution firmware gets updates frequently. The latest patch is 5.00 M33-6. You can install 5.00 M33-6 very easily, whether you already have 5.00 institution firmware or if you're upgrading from a M33 institution firmware below 5.00 M33.
