This is all irrelevant. What was good for the 1.50 PSP does not mean it works on the PSVita, or even the PSP emulator.SifJar wrote:1.50 had security measures, they were just easily bypassed by kxploit
No one has mentioned the memory stick swap exploit before that one =P. good times good times!!!! Oooo and the birth of POPstation was preety amazing as well! Im hearing at gamestop and bestbuy the vita will be easy to hack! lets hope they are right.SifJar wrote:1.50 had security measures, they were just easily bypassed by kxploit - extracting DATA.PSP from an EBOOT and putting it in a separate folder named the same as the first but with a % at the end or something along those lines (the exact details escape my memory). IIRC, 1.00 was the only firmware to have no security measures and allow completely unsigned code to run without problems.Xian Nox wrote:I don't remember there being a memory overflow kernel mode exploit.

To find kernel exploits, we need a better understanding of the firmware. With the PSP, it included reversing portions of the firmware to look for vulnerabilities. At current, no one has released any tools to decrypt the firmware. So, we are a long long way from a CFW, if one is even possible on the Vita. Also, no kernel mode == no flash0 access.
Sony long ago found a way to counter such flash rewrites: encrypting and signing. The 1.50 OFW was the last to not include these security measures completely iirc.
So, before you get your hopes up: no CFW, not for some time at least.
The PSP emulator contained in the PSVita is using OFW 6.60.Kosuke wrote:Just thought i wonder how hard will it be to find out the firmwire of the psp emulator cause i think if it has 1 we can work from there.
