  • How to Capture Your iPhone 3GS iBEC and iBSS on Mac
    This guide will help you to get some important iBEC and iBSS files for your iPhone 3GS which will be required for jailbreak once it is released.

    Things you Need:

    We recommned you to backup before following the steps.

    Follow the steps below to get the files:

    Step One:

    Click and Hold the Finder icon in the dock and select Go to Folder.. from the pop-up options.





    Step Two:

    Type "/Users/'your username'/Library/Caches/Cleanup At Startup" in the pop-up box and click the 'Go' button. (Remove '' part from 'your username'). This will open the 'Cleanup At Startup' folder in the Finder window. Leave this window open.





    Step Three:

    Create a new folder, 'MOST IMPORTANT FILES IN THE WORLD' in this example.



    Step Four:

    Open iTunes and connect your iPhone 3GS to the computer in DFU Mode. Select it from the list of devices in the left sidebar. Hold option and click Restore button. Navigate to the iPhone firmware you downloaded before, select it and click 'Open'.



    Your iPhone will now begin restoring to the 3.0 firmware. You will be warned that this will erase your phone. Click the 'Restore' button to continue.



    Step Five:

    When the restore is in progress check the "/Users/'your username'/Library/Caches/Cleanup At Startup" folder you opened before. A new folder will appear with a name similar to 'iPhone Temporary Files.noindex'. When the folder appears, select it, and press Command+c to copy it to the clipboard.



    Open the 'MOST IMPORTANT FILES IN THE WORLD' folder you made before and paste 'iPhone Temporary Files.noindex' there. This will make a copy of your unique iBEC and iBSS.



    Make sure you finish these steps before the restore is completed and you're done!

    All the credit for the technique goes to DevTeam

    P.S. Thanks to Melech518 for all the screenshots!

    UPDATE: If you have already obtained a USB Dump from Purplera1n.com, no need to follow the guide

    UPDATE 2: Seems that Purplera1n just gives iBSS so if you want iBEC as well (can't restore to totally stock 3.0 without it), follow this method as well.

      I have used iClarified's steps and the files almost immediately appeared in the folder I set up when i hit restore in DFU Mode.

      My question is that the iBEC file has a "Zero" file size. Is the size supposed to be "Zero"?

      iBEC.n88ap.RELEASE.dfu (Zero KB)
      iBSS.n88ap.RELEASE.dfu (104 KB)

      EDIT:
      I did another restore in DFU Mode and this time the files are now at 104 KB each. Don't know what happened the first time...

      whats irritating is how all of a sudden the forum got so big in the past year from all these impatient people. i have been following the forum before i even registered and all my questions were asked after doing a bit of reading. i still have questions about stuff but i dont usually post. i dont know everything by any means. but i just read as much as possible. usually that helps when people read. yes it can be frustrating to come into the middle of a topic that has a whole lot of pages! but all it does is fill up more useless crap for us to read through when people start typing away! and now there is hundreds of users that just join to ask some question that was already answered, and never post again. which there is nothing wrong with posting a question, just aslong as its not posted time and time again.

      quick question, after the dfu mode, grab the files, restore from backup....are your applications on the springboard in the same order before the dfu restore?

      If you have the 3.1 beta Can you still capture these ?
      Im doing restore right now and it grabed the IBEC at 103kb and IBSS at 107kb And im on 3.1beta Will these files work for the jailbreak in future?

      i 3rd that... one thing i dont understand is... the dev teams and sweating the butts off to make a jb for everyone and not charging anyone... if they wanted to they could charge you or better yet they dont even have to bother making it... and the end you'll be stuck....

      so stop all you stupid whinning and crying about the devs to hurry up. and for the guys who want proof for the jb get a life and wait.

      the dev team are doing their best to keep you all happy just appreciate it and wait till they release it... if your so keep on having a jb phone revert back to a 3G and if your keep on waiting keep at it guys!

      respect to all that deserve it!!!

      i agree...as much as id love a jailbreak now, slow and steady wins the race. im sure a 3gs jailbreak/unlock wont take 6 months but at the same time i know that it would not take 6 days either. if i put in a heavy financial investment on my 3gs, i want to make sure the software i run on it is reliable and not rushed/half-assed. I will refuse to put in rushed code...

      Dev Team, keep up the solid work. Your tested code has made many people happy and i'm sure you wont disappoint us this time...i'll be eagerly waiting for your polished product whenever it comes out (hopefully soon hehe)

      Worked like a charm. The Auto Grabber in DFU mode grabbed both files on Windows 7 the very first time.

Have a great night and add more useless posts after this.
      Haha how very cock sure of you sir, when you have finished flaming me can you release the jailbreak for the 3GS almighty one?

      My previous post was to diffuse your anger in a not so "i was joking about the iPod Touch to see what kind of a reaction i would get" kind of way. Congratulations on having absolutely no common sense and realising this.

      This isnt something i really care about and i dont feel the need to defend myself against you now, so please dont reply even if you dont understand this.

      On the topic at hand, we now have a video from the Dev Team of an ultrasn0wed 3GS.

      So I have done the rain dump and got the file from that... but I dont see a iBSS file there. Should I?? I have also done both restores in dfu and out of dfu. Both times I got the iBEC file. Do I need to do it one more time with the method above to get the iBSS??

      So, you were able to determine my emotional state based on the text I typed, yet couldn't spell "realizing"? Interesting. English a second language, or are you an illiterate psychologist?

      This isnt something i really care about and i dont feel the need to defend myself against you now, so please dont reply even if you dont understand this.
      You're right. You didn't care so much you took the time to reply, and, point out how much you "didn't" care, since non caring people just reply for shits and giggles.

      Oh, and I replied not only to make you look foolish again, but because this time I could actually understand you're gibberish, so it was easier to mock you. Simple is not only a word, but a name most people would use to address you in person I bet. So, does this give you a headache after you read it? Nose bleed maybe? Take a deep breath. You've only been owned on a forum. It only stings for a little.

      Hahahaha, narrow minded tit. 'Realizing' is not the english spelling of it. It is the american english spelling of the word.

      The real english spelling of the word is 'realising'. I'm english. I know.

      And to be honest bud, you said the iPod Touch 2G took 6 months to do so we should be patient for the 3GS release, but if you knew anything then you would know that the same 24kpwn exploit that took 6 months to develop could be used on the 3GS with only a 10 line change to redsn0ws code. So comparing this release to the iPod Touch 2G (which noone cares about anyway) to the 3GS is rediculous.

      Take away the fact that you cant spell 'realising' in the english language, and that you have no idea of what actually goes into developing the jailbreak, ye, you pwned me

      And due, you can own me in an internet forum all day long. Congratulations. There is more to my life than internet forums. lol.

      I hope for you that it is written on your gravestone: "the internet forum pwner of people, and defender of the less than 10 people that care about the ipod touch"

      First, you quoted someone else. I didn't say anything about the iPod Touch taking 6 months to jailbreak. That was someone else, so calm down, focus, and spend less time telling us how the British mispell words. No one's impressed with you or your Gilligans Island. Get your facts straight BEFORE you reply. That way you don't make yourself look like a fool. Oops. Too late.

      Second, I've been hacking and modding for a decade. Years of cooking ROMS for WM devices, so excuse me if I laugh hysterically at your cliche e-fight response that "I don't have a clue as far as what it takes in developing". What are you, 15, 16 years old? You act like a angsty little teen with a Napolean complex. You don't have to prove anything online by being a douche with silly opinionated comments, then constantly attempt to re-attack with more nonsense. You're not gonna win an award, and the only thing you're gonna gain is a reputation as a forum troll and douche. Congrats btw, since I think you accomplished those goals already.

      Cheerio! Time for tea and strumpets and a quick walk from the flat to see the Queen! w0ot! haha

      Wow, you are so celever you managed to judge me and pin me into an american persons stereotypical view of a british person WHILST fulfilling the rest of the worlds steretypical views of americans.

      You truly are king od forums. You go girl.

      And who cares about WM?

      WM is DEAD old man

      Typical arrogance.

      WM is dead. Died a few years ago, around the time I started modding my iPhone(s) and quit developing ROMS at the xda-dev forums. lol You're such a tool. Every time you post you stick your foot in your mouth.

      So what 'mods' have you achieved on your iPhone so far?

      And a re-cap - you started flaming me because you took my 'Noone cares about the iPod Touch' post a little to seriously. I said after your first post i was muckin about, does it make your scrawny *** feel a tiny bit powerful in this world posting the same **** over and over again. Old people, always living in the past. WM zzzzzzzzzz lol

      I just hope when im about 50 years old like you i can feel a buzz off of internet forums and developing ROMS for out-dated POS WM. Do you ever go bird watching or train spotting? They both have the excitment level of the rest of your life.

      And the whole british monarchy queen thing - the only people it means anything to is tourists. And with statements like that your showing your narrow minded stereotypical american persona again. I really feel for the intelligent americans who can look at their country and laugh at people like you.

      I may be making myself sound like a tool to your stupid ***, but your making yourself sound like a dumbass boring middle aged cock.

      So now because I was a WM developer prior to the iPhone coming out I'm 50 y/o? haha k. Good one. Did ya get that off a Mr. Bean episode?

      I appreciate your constant attempts to humor me with your weak Internet cliche's. It's actually entertaining.

      Your last comment mentioning your cawk is a clear hint at Projection. I'd talk to someone about that. Maybe this is why the British like to say they "smoke fags" instead of cigerettes. hahahaha
