iBoot iPhone 5s Decrypted, Bootrom Exploit for iPhone 4S, 5, 5C, 5S is coming

As we have known that iH8sn0w already discover a major security exploit in iOS that allow him jailbreak all A5X and older devices on any iOS firmware version with bootroom exploit. Simply means that hacktivating iPhone 4S or iPad 2 wouldn’t be any problem in the future, only for himself at the moment.

Another good news is, that Winocm has managed to decrypt iBoot for the the 64-bit iPhone 5s which makes exploitation much easier.


Winocm posted a screenshot of the decrypted iBoot to Twitter earlier today saying, “64-bit iBoots anyone?”.

He followed that up by noting,

iPhone 5s iBoots are definitely very interesting to look at. A7 is indeed a total reimagining of the iPhone architecture. Also, looks like the CPU implements the full AArch64 exception model. I think the part I like the most about the A7’s boot chain is the new boot monitor.

Though it’s not a bootrom exploit yet, but it could be the most important update for iOS jailbreaking over the years since no one has found a powerful bootrom exploit that will last long since the release of Limera1n by GeoHotz.
So we probably will see that jailbreak iOS 7.1 or even jailbreak iOS 8 in the future.

winocm will to hold on his discovery for the moment, but plans to use it in the upcoming iOS jailbreak developments. It looks he is all ready to jailbreak iOS 8 this year without any delays.

If you don’t really understand what it means, we can simply have easy jailbreak in the future if bootrom exploit is found up to iPhone 5S models, and you can even bypass iCloud in case the exploit and its tool released in near time.
