Baseband 05.12.01 Exploit Discovered by GeoHot, No ETA for release


Finally another good news for those iPhone unlockers who updated their iPhone to stock firmware 3.1.3 knowingly or unknowingly. GeoHot discovered a working exploit in baseband 05.12.01, GeoHot already posted the hash of his BB exploit for safekeeping check his tweet here. Here GeoHot tweeted the hash tag of his BB crash.



Update : Geohot is not going to release his unlock this weekend. We were confused with Motorama this weekend part, actually GeoHot was talking about Motorama event where he is going to showcase his green robot [Check Here] So no unlock this weekend and possibly we may have a release after OS 3.2 this march with iPad launch or may be with after iPhone 4G/ OS 4.0 in June/July event.


As you know Sheriff  Hashim founds a crash for latest baseband [check the story here] and he handed the exploit to iPhone Dev team. Musclenerd also confirmed that the crash is very promising. Musclenerd didn’t promised any ETA for the Ultrasn0w update, may be dev team is looking forward to save the exploit for OS 3.2 or may be for next gen iPhone and OS 4.0

iHackintosh fan Visnet tipped us the IRC conversation between him, GeoHot and Musclenerd. The following conversation clarifies that both GeoHot and Musclenerd now have a working exploit for latest baseband. Both hackers are unsure if they have same or different crashes under their hood.

<visnet_> What does geohot tweet mean?
<%geohot> its my bb exploit for safekeeping
<%Par4doX> geohot: did you turn that over to the dev team or are you doing something with it?
<%geohot> my days of turning things over are done
<%geohot> i hope its different from the one they have
<%geohot> but they prob already have it
<%geohot> its the one i orig wanted to release blacksn0w with
<%Par4doX> it’s still there in the new bb
<%geohot> yep, just checked
<%geohot> but then opted to use xemn since it was public
<Evan> Oo, it carries over from 05.11 to 05.12?
<%geohot> why wouldn’t it, apple doesn’t fix things proactivly
<@MuscleNerd> geohot we prob should figure out a way to know if we have same exploit double blind,
otherwise we may release 2 different ones at same time
<%geohot> any suggestions?
<@MuscleNerd> not sure how to do that without making it easy to brute force though
<%geohot> yea, i salted the hash
<@MuscleNerd> yeah
<@MuscleNerd> hmm maybe if we both hash the stack dump
<@Confucious> Can you two take this out of public sight?
<@MuscleNerd> the stack itself, not the header before it or the registers after it
<Her> muscle: any notice about the exploits are the same ?
<%geohot> we are working on it
<%geohot> cryptography, perfect for people who don’t trust each other

    Even though I am quite pissed off, it is funny situation here in Brazil …. here all the operators have to officially and legally unlock your iPhone if you ask them to do so (if you bought your iPhone here of course) … new law, locked phone are illegal now …. I have the f***ing 3.1.3 new bb but not even the operators, after discussing 2 days directly with Apple Brazil, can unlock this version … putting them into illegal situation …. think about to suit them :-))) do they wait for geohot or DevTeam ?? :-)))

    Geohot, please make all these people happy, including me, praying for your limera1n, and release it soon !!!!! PLEEEEESSSSEEEEE

    Hurry up and stop pi**ing around, 3.2 and 4.0 has been out for a while now.

    I got my iPhone 3GS 32Gb locked after updating it to 3.1.2 (7D11) firmware (05.12.01).

    Now i could Jailbreak it by using blackra1n and could install Cydia. I tried to Unlock it by installing sn0w from the icon that blackra1n creates in the phone but was unsuccessful.

    Does anyone knows if is there anything i can do to Unlock my phone? Maybe downgrading my firmware to (05.11.07) “if possible”.

    wtf, its april 19, and there is not a new software/program to unlock the iphone 3g baseband 05.12.01
    please help me, i cant use mi iphone simcard

  8. Eddie C April 17, 2010 Reply

    So What’s up with the new JB? I thought when Apple releases their 3.2 and 4.0 firmware, the JB will be out. Everywhere I read, it says that Geohot and the Dev Team is waiting for Apple to release the new firmware…well, its been out. Does anyone knows if that program Thunderst0rm from the Swiss students is fake or real??

    If nobody has released a unlock for baseband 3.1.3 then surely apple won’t bring out next o.s 3.2????
    please take it out

  18. george March 7, 2010 Reply

    they should only release the firmware 3.1.3 with baseband 5.12 when its ready to use, apple sucks. i am using iphone since its launched and every time i upgrade i have to wait for the tool to release. now i cant use it since i upgraded the baseband to 5.12. s phone is for our daily use, its not that we have to wait for the exploit to release to use the phone or buy a temporary phone until it releases. Apple is really shitting me.

  19. Milo March 5, 2010 Reply


    I hope the wait to publish it until Appel release V4.

  20. Aj March 4, 2010 Reply

    Cracks me up all these posters wanting a release now!!! Can’t you people think further ahead in the game than your own ipod/iphone?

    What’s the use of wasting any valuable exploit on this useless 3.1.3 firmware?

    OS 3.2 OR 4.0 is the way forward…

    I got a new ipod touch 3g running 3.1.3 so there is no way for me to downgrade. I got it so I could use it with orangegadgets gps receiver, but it must be jailbroken to use. I’m confused, in one instance it is said that Apple never goes back and fixes old crashes and yet you are thinking of waiting for the next release so they don’t fix it to subvert the jailbreak. Also you’ve already said you have found a crash maybe two so why won’t apple look for them and fix them in the next release. Seems to me use what you have now because it may not be there next time. Anyway, do what you gotta to do and I’ll wait. Thanks

    I have a iphone with OS 3.1.3 baseband 5.12.1 and bootloader 5.9.I uesd fuzzyband to downgrade to older baseband but it said “not support”.Please help!!!!!!!!

  27. Mike_o|ive February 25, 2010 Reply

    @Mr Max, no need 2 get pushy about this new jailbreak these guys are genius and have released some great hacks so why not just be patient and let them work there magic because I have faith that they will help us all out

  28. Mr Max February 25, 2010 Reply

    Whatever. SO they found an exploit, big deal. Make a jailbreak already, or maybe you cant

    That exploit could be fixed in 3.2 then what will you so, nothing.

    Just release the jailbreak, who cares about the unlock.

    Prove to us that you are still all that powerful.

  29. Fonzie February 25, 2010 Reply

    When you “accidentally” upgrade to firmware 3.1.3, do itune automatically upgrade to 05.12.01, as well bootloader to 5.9 as well? If i have 3.1.3, with 05.12.01 baseband and 5.9 bootloader, will it ever be unlockable??

    I know there’s a way to downgrade 3.1.3 back to 3.1.2, using fuzzyband, but my phone is still “virgin”, is there a way to bypass that step? also I have 5.9 bootloader.

  30. Mike_o|ive February 24, 2010 Reply

    If you have 3gs 3.1.3 (newbootrom) could you not just put your iPhone in DFU mode then connect it to a different pc or mac with iTunes installed that hasn’t upgraded to the new OS 3.1.3 hence downgrading your iPhone? Will this work or is it not possible pls let me know ???

  31. Thrasos February 22, 2010 Reply

    The point is when they are going to release them not that they have found a solution. So when are you going to give as the jailbreak and unlock for the 3GS 3.1.3 with 5.12.01 baseband??????????

  32. ligur February 22, 2010 Reply

    aaargh! just want jailbreak, no need for unlock. Any ideas?

  33. ihateapple February 21, 2010 Reply

    so if they have 2 different ones will they release one soon or wait longer???
    i hope one is released within the next week.
    got a brand new iphone that i cant even use yet…

    so if this is the second one to be discovered when will it be released? I got a brand new iphone 3gs and my friend unlocked it for me, forgot to tell me not to update the OS with apple and i did, to 3.1.3… i was so pissed and i cant use my phone, i live in germany so its totally impossible without a jailbreak/unlock…. but since this happened ive spent so much time tryin to figure all this out that i have learned alot about basebands and all that other shit… and i have learned that apple sucks ass and i will never buy a product from them again!

  48. be3n February 20, 2010 Reply

    I hope they resolve this. we don’t want to see exploits waisted. they will hopefully wait until 3.2 (expected end of march with iPad release).

    (probably same exploit)
