Legendary iOS hacker MuscleNerd tweeted today that there’s no bootrom exploit out there for A5+ processors, this could mean that iOS 7 jailbreak might end up taking quite some time.

iOS 7 jailbreak MuscleNerd rules out possibility of a bootrom exploit, iOS 7 jailbreak might take time

 

An exploit is required to jailbreak an iOS device. There are two kinds of exploits, a bootrom exploit and a software level exploit. The latter can easily be patched by Apple through a firmware update, so even if such an exploit is found, the jailbreak is usually limited to one firmware. Bootrom exploits are hardware based and can’t be patched in devices that have already been shipped to customers. This exploit allows at least a tethered jailbreak on any particular firmware. Unfortunately, no bootrom exploit has been found in any iOS device processor after the A4, which powers iPhone 4, iPod touch 4G etc.

 

There were rumors going around recently that there was a bootrom exploit for A5 and high processors out there, but MuscleNerd has flat out rejected these rumors, saying there’s no even a bootrom dump. There has been talk of an iOS 7 jailbreak, notable developer Ryan Petrich posted an image recently what supposedly was an iPod touch 5G jailbroken on iOS 7. If such a breakthrough has been made, its likely that a software based exploit has been found in iOS 7.

The fact that there’s no bootrom exploit means that iOS 7 jailbreak will take time. Dealing with software level exploits is cumbersome, and a lot of work has to be done before the jailbreak is ready for the public.
