Breaking News: 2.60 Firmware Exploit Found - Kernel Access!
A developer known as hitchhikr of "hitchhikr SoftWorks" and coder companion Neural have come out with a Proof of Concept of a 2.50/2.60 Firmware Exploit! Once implemented and fine tuned for "normal user" use, this will bring 2.50 and 2.60 Firmware up to the same homebrew capability that 1.50 PSP owners enjoy with FULL kernel mode access - although Grand Theft Auto: Liberty City Stories will still be required, just like with eLoader.
Speaking of eLoader, Fanjita is already working with hitchhikr on incorporating this new exploit into an easily executable means via eLoader. After a brief chat with Fanjita, he's told us that you can expect some generic application for developers to hopefully be released in the next 24 hours. It will take a bit longer before something useable for non-devs will be released.
The exploit takes advantage of an added security check in 2.50/2.60 Firmware for sceKernelLoadExec, which is responsible for loading EBOOTs, but Sony also accidentally added an overflow bug, which means this exploit will not work with 2.0 and 2.01 Firmware.
But don't start upgrading those PSP's yet until a viable means of implementation is released! Also, this breakthrough does not open up the possibility of a downgrader due to the protection in the IPL in 2.50+ firmware. Although speculation has already begun that this will open the door to the decrypting of 2.70+ Firmware, allowing it to be emulated a la Devhook.

一位来自 "hitchhikr SoftWorks"名叫hitchhikr名叫的开发者和他的伙伴,程序员Neural带来了一个2.6,2.5firmware破解概念的证明。如果能够被良好的执行,并最终能够提供给一般使用者使用,那么2.6,2.5firmware的PSP将拥有完全核心功能的使用权限,这样一来,他们将享用和1.5PSP一样的homebrew(非官方程序)运行能力。同时,你还需要一张GTA的游戏,这个功能的使用将类似于eLoader
eloader方面,Fanjita已经开始和hitchhikr合作来把这个破解的突破合并到eloader中,使他能够通过eloader来执行。通过和Fanjita短暂的交谈得知,在接下来的24小时之内,将会发布一些为开发者使用的应用程序。过一段时间之后才会有为一般使用者使用的程序。
这个破解得益于Sony为sceKernelLoadExec(通过它才能运行程序)在2.5,2.6firmware添加的安全检查的溢出漏洞。所以说,这个漏洞对2.0和2.01firmware是无效的
尽管通过这个,从理论上已经可以开启破解2.7firmware的大门。允许它通过Devhook来模拟。但现在先不要急着把你的PSP升级。等到一个可用的执行方式发布之后再作考虑。同时,这个方法也不能够对2.5以上的PSP进行降级。
