Famous iPhone Dev Team Member MuscleNerd tweeted about the iPad 2, A5 Bootrom and how difficult it is to Jailbreak the Bootrom/ iBoot of iPad 2. In his tweet he mentioned that Userland from Comex would be coming much quicker as compared to the Bootrom exploit as the Bootrom is actually inside A5 processor which would require some very advanced decapping and optics.
Here’s what he has tweeted:
So far, our tests have shown my theory might be right 🙁 (Once the A5 bootrom is off, it stays off until power cycle)
(This wouldn’t be too surprising since they do did similar thing on 3G/3GS baseband CPU. But it’s annoying)
@paulroe83 the bootrom is actually inside the A5, so that would require some very advanced decapping and optics
@borgqueenx if I’m right, it just means userland A5 jailbreaks will precede bootrom-based ones (I still hope I’m wrong though)
