I'm working on a downgrader for 2.01 (and hopefully higher) and have now come to a point where i need some beta tester's with 2.01 firmware.
I only have a 1.5...that i dont wish to upgrade.
Please PM Me , email me (email@example.com), or post here if you are interested.
Be warned, by trying this you could brick your PSP because it is an untested method and anything could go wrong. It would be wise to play it safe and wait for a confirmation that it actually works before risking your expensive PSP investment. If you cannot wait and want to test this, let us know of your results, otherwise, please be patient.
