  • Dev-Team Confirms: New Bootrom Defeats 24kpwn

    image via StealthBravo.com

    As noted here on MMi last night, new iPhone 3GSes are shipping with an updated bootrom that is resistant to 24kpwn. Dev-Team member MuscleNerd confirms that the new bootrom, iBoot-359.3.2, is no longer vulnerable to the memory segment overrun exploit.

    This is the first time Apple has upgraded the bootrom during a normal production cycle, rather than when a new model is introduced. The bootrom is a snippet of code that runs at startup time, and checks on the status of the boot image. It's generally used to verify that the image has not been corrupted, but can also be used to check for unauthorized firmware. The 24kpwn exploit - otherwise known as 0x24000 Segment Overflow - bypassed the signature checks on iBoot and allowed unsigned firmware to be loaded. The new bootrom makes that impossible, so currently shipping 3GS phones cannot be jailbroken until a new exploit is found.

    To determine if your new 3GS is running the new bootrom, just check System Profiler while the phone is in DFU mode. Versions of iBoot prior to 359.3.2 should still be able to be jailbroken using known methods.

      Cheers for that, you'll be missed!

      Another exploit will be found. If there isn't, ah well. Like I've said before, the iPhone is still a great phone, open or not.

      Apple has never been into being open. If they were, Microsoft wouldn't have been as successful as they were being the "open alternative" OS and would've just failed like Gates and Allen did with Traf-o-Data.

      I'll miss theming, but I still love my iPhone, regardless.

      But this is how it works: exploit found, exploit fixed... another exploit found, etc. Don't blame Apple. They are doing what they are supposed to do, period.

      But man, I'll really miss theming.

      The funny part of this is that I'll bet the devs had already planned on this hole getting patched and have been working proactively for a while to find the next exploit...

      If the only reason Apple doesn't like JBing is because of cracked apps then why can't apple and cracked app installer devs reach an agreement? Besides it's illegal anyway

      My fiance and I go through this discussion all the time. Apple has rights to it product, I have a right to something I bought. I defend the latter. She looks at all the neat things my phone can do with envy. She wants to JB, but she says she doesn't want to risk her phone. I feel that, because I have had issues..with my JB iPhone's but have always been able to resolve them. Anyways, Apple is going to protect their little precious and I will (as long as the Dev Team provides a way) continue to make the iPhone MINE!! The way I like it, the way I want it. I purchase apps from the app store, I DO NOT download stolen apps (I am a COP). But I will chose to JB, risk blowing up my iPhone if I chose. Besides I've gotten many Blackberry friends to turn to the dark side of the force..

      I was just thinking the same thing. I'm seriously looking into the Android.

      Unfortunately Android is not the iPhone killer we were all hoping it would be. YET! (hopefully)

      Some one said (I can't think of a single device that's not exploitable. Someone will find a way to do it, especially now that there's money to be had from generous jailbreakers and paid-for apps on Cydia and the like.)
      I use to hack DTV, until they changed the card, been 4 years now, No hack. Dishnet just changed their card, still not hacked.

      If there comes a point wherei can't JB my iphone then i will reluctantly leave the apple brand. I JB mainly for themes and slingplayer over 3G and spend a great deal of money on the appstore and itunes store.

      Apple needs to give people what they want or loose a hell of a lot of loyal customers. Simples!
