It is not yet possible to downgrade a PSP 3000 series.
Nobody knows yet but possibly when the PSP 3000 comes out. October
No, the e-1000 is meant to be a budget model of PSP's but the 3000 is the top of the range model however if you are looking to buy one then get the PSP 3000 which you can buy second hand for £55 and also the PSP 3000 is so far the most successful PSP yet and it even beats the DSi but don't get the PSP Go if you were interested in it since it's quite bad and need some proof, the PSP 3000 was released in 2008 and still remains in production but the PSP Go came out in 2009 and came out of production in 2011
I do not believe that the Pentagon has been hacked yet but there was security breaches. Gary Mckinnon
If your talking about the psp 3000 aka psp bright, there's no offical firmware mod for it yet. However there is a video of someone who claims to have modded it. See psp-hacks.com for info.
If on the sides your psp sticks out, you have the 1000. If its slim but has no microphone, you have the 2000. If its slim but has a microphone, you have the 3000. The psp go hasn't come out yet but on that the screen slides up.
well, first of all, the 6.20 update hasn't been cracked yet, you yah will have to un-install that update. And, if you have a PSP-3000, you can't hack it because of the hardware and the integrated firmware in the psp. So it all depends.
Modern Warfare 3 hasn't been hacked yet. Wait a couple of years.
Yes. Whenever 6.30 comes out, there will be a ChickHEN loader to get CFW.
Pandora Battery is a TOOL to GAIN Service Mode Access for the PSP. That's it. Now PSP 3000 ARCHITECTURE is Different from PSP 1000/2000. However, when a Pandora battery is inserted in the PSP, it does TRY to Activate the Service Mode, But PSP 3000 doesn't let it. Conclusion: Do not Throw Out Or Convert your Pandora Batteries (into normal ones) Just Yet. You may find it useful in the Future. In technical Terms: Pandora Battery can only "Activate" the Service Mode. There is no IPL to penetrate & overwrite the NAND-FLASH0.
Unfortunately there is not at the moment the only way to do it with a 1000, or 2000 is to use a spare battery. Though you can check if they have any way to use a jigkick battery with a 3000 yet
