Cool HELP! PSP 2000 or PSP 3000

Hey I was wondering wheter I should buy a psp 2000 or the new psp 3000. I was wondering because no one has broken the hombrew line on the 3000 yet and I do want homebrew on the 3000. Also do you think they will just make another one next year? Advice? Thanks.

the "newer" PSP 2000 can not be hacked because of the TA-88V3 boards.
One reason why it couldnt be hacked is because it couldnt read the IPL off the pandora battery because the newer version reads smaller versions of the IPL, i think...
They were thought that the PSP 3000 would have this motherboard but it turns out that it has an TA-90, which might be able to hack, but no one knows for sure.
Make sure when you buy one, it doesnt have an 4.xx firmware i think, those are the ones that cant be hacked.... yet

The best homebrew PSP is the 1000 series because of the 1.5FW.

I wouldnt get an 3000 yet, i would wait awhile. If you are going to get an 2000, make sure you get an older one.

When the PSP boots, the boot code (aka pre-ipl or ipl loader) loads the ipl from either the nand or memory stick. The IPL is splitted into pieces of 01000 bytes.

First 0xA0 bytes of each block is a header for the kirk hardware command 1. It contains keys, the size of the cipher data, and two hashes, one for part the header itself, and another one for the body. The 0xF60 remaining bytes are the ciphered body, which will decrypt to 0xF60 plain bytes… if the hashes, which are checked by kirk hardware itself, are OK. (Note: ciphered body can actually be less than 0xF60, in this case, remaining bytes are ignored… before TA88v3)

What has Sony added to fix this?

The answer can be found in 4.00+ slim ipl’s. They decreased the size of the ciphered body to 0xF40 to leave 020 bytes at the end of each block (at offset 0xFE0). In newest pre-ipl’s, these 020 bytes have a meaning.
This protection also destroys any possibility of downgrading below 4.00, as these new cpu’s won’t be able to boot previous firmwares ipl’s.

Summary: basically, all security of newest psp cpu’s rely on the secrecy of the calculation of those 020 bytes. If pre-ipl were dumped somehow, the security would go down TOTALLY.

That sucks I will stay informed on the web and check if the 3000 can be hacked... eventually.

i think they are close, at least they figured out why they couldnt hack it yet.

i think when the 3000 series can be hacked, most of them would be gone within a couple of days.
Like when they found the Lumines (non greatest hits) exploit to hack the 3.50 FW. The game was sold out everywhere or were charging a lot. It was going for about $90 on Ebay.
Sony even told gamestop to pull it off their shelves.
