Yeah guys, more bad news regarding iPad 2 jailbreak. After iH8sn0w's confirmation regarding Geohot's Limera1n exploit being patched in iPad 2, MuscleNerd, member of iPhone Dev-Team has confirmed that Poxinninja's SHAtter exploit has also been patched in iPad 2 by Apple.
iPad 2 is running bootrom version iBoot-838.3 which was compiled by Apple back in March 2010, meaning Apple engineers fixed both loopholes long before both exploits (Geohot's Limera1n & Chronic Dev-Team's SHAtter) were found.
@hooners96 right. I guess this is a bit of a win for Apple engineers…they fixed both holes long before either exploit was developed.
@fr0st SHAtter can’t work at all with the “thing” I referred to gone
This means any early iPad2 jailbreaks will have to be purely userland
Early testing also seems to show at least one thing SHAtter depends on was gone by March 2010 too
iPad2 bootrom version iBoot-838.3 means it was compiled March’10. Seems geohot guessed right: limera1n was already closed
So what are the options now? We know that current jailbreak tools are using Geohot's bootrom based Limera1n exploit which has now been patched by Apple in iPad 2, so the hackers either need to come up with a new bootrom exploit or a userland jailbreak from specialists like Comex could do the trick to jailbreak iPad 2. Chances of bootrom jailbreak for iPad 2 are bleak as bootrom exploit is not easy to find and even if hackers find one in iPad 2 A5 chip, they won't release it since iPhone 5 launch is expected this summer and it has also been confirmed that iPhone 5 is using same A5 dual-core chip which is used in iPad 2.
For those who don't know, bootrom exploits are present is the hardware and they can't be fixed by the software updates. Once a device is jailbroken by using bootrom exploit, it's jailbroken for life. Userland jailbreak on the other hand is based on iOS exploits and can be fixed by the software update by Apple anytime.
