So we have all this custom firmware out now, And also DevHook with 2.71 loading homebrew from the XMB.
We have access to flash on 2.5 and 2.6, doesn't that mean we can use the custom firmware on 2.6? So we can load homebrew from the XMB?

The 2.5/6 exploit was discovered in GAME mode, therefore, the exploit cannot be ported to another system area.
Besides, the abysmal available amount of memory and the extremely limited range of functions that can be used almost guarantees that such an execution of code from the VSH means it is impossible.
Custom Firmware is possible in 2.60, but it would only be a modification of the VSHMAIN.PRX module as in Dark_Alex's Proof of concept, except with less features and probably less stability.
This does not mean by any stretch of imagination that the 1.50 Proof of concept's module will function on 2.60. It has so many more other modules it needs to load, and the file is a probably completely different structure.
The PRX would have to be re-coded for each individual firmware revision it is being built for. So, if someone builds a Proof of concept VSHMAIN module for 2.50 or 2.60, it will be quite an achievement.
Don't expect a custom firmware for 2.xx just yet though, it will take some time for something like that to emerge.
Note that it would most probably not work on 2.01 as the exploit may not function correctly, if at all, on that revision. Any custom Firmware would only happen on 2.00, 2.50, or 2.60. Definitely not on 2.70 or 2.71, as we have no means of executing any code at all for now (If ever). |

Points: 211.93 Donate | | | Hmmm.. I suppose the best way would be to do something similar to the 1.50 proof of concept. Or, patching the RAM to enable temporary XMB loading abilities.
This would not allow 1.50 kxploited EBOOTS to run, only v1.00 ones. Meaning no ISO loaders, Flash Mods, etc YET.
All these sorts of apps would have to be re-coded. What would be cool, is if Devhook was ported to 2.xx. This way, you can emulate 1.50 lol |

Points: 21.55 Donate | | | the only problem with poc is that 1.5 can all ready use hb (poc only adds 1.0 eboot abilities to the 1.5 eboot loading capabilities) where as 2.6 its blocked, also i think the homebrew loading in devhook may be a direct result of devhook and not modding the firmware. BUT the supposed "0x89" may have the awnser you require if it is true?.
also the major system prx's may require encryption to fuction properly?
