RecBoot – OS X and Windows

I spent some time rewriting RecBoot last night, and added some new features that makes RecBoot more user friendly. This is, by far, the biggest update I have ever written for RecBoot.

For Mac OS X, please visit http://sebby.net/.

This update to RecBoot provides a few things, so here’s a list:

1. Improved, Clean, User Friendly GUI – I tweaked the GUI a bit, played around with the buttons, and also added a Credits box.

2. Cleaner folder – When you download RecBoot, you get a .zip with several .exe’s and .dll’s (would have been much smarter if I compreseed this into SFX but oh well). Now, those files get moved when you open RecBoot. (Except LibUSBDotNet, don’t delete that or RecBoot may not start)

3. No more copying iTunesMobileDevice.dll into the folder

4. Recovery Detection – If you are trying to downgrade, per say, to check if you are in recovery mode, simply open RecBoot. If it says your device is connected in Recovery Mode, then congratulations, you can downgrade! Otherwise, you can’t.

In order to use it, you must have the following already installed:

1. .NET Framework version 4.0

2. iTunes 9.2 or later

3. LibUSB (only needed if you want to use the recovery detection feature)

    it doesn’t work on Win7 x64.
    The path to iTunesMobileDevice.dll is wrong (should point to c:\Program Files (x86)\…).
    After copying this dll, RecBoot can’t find ASL.dll, then CoreFoundation.dll.

      Thanks! I’ll try to push out a version for 64 bit users soon.

        hey thanks it worked for me i have win7 x86 i just copied the .dll files into the normal program files directory and it worked!!!

        October 16, 2010 at 10:33 pm

    • Islam

      ASL.dll and CoreFoundation.dll both are in: C:\Program Files (x86)\Common Files\Apple\Apple Application Support\
      I guess you have to run RecBoot from there (like with Blackra1n), but i’m not sure, i haven’t tested myself

      October 1, 2010 at 10:08 am

    • traxinv

      Hey all the files you need are in “C:\Program Files\Common Files\Apple\Mobile Device Support” Copy ALL those files to “C:\Program Files (x86)\Common Files\Apple\Mobile Device Support” Or other way round either way there will be a crap load of files in one and like 2 in the other… enjoy! :)

    A Win 7 64 bit version would be great. Any info out there on how to do it manually if we can’t get a 64 bit version? My upgraded iPhone 3G is killing me it’s so dog a$$ slow! Thanks!

      You could try manually placing the dll’s in the RecBoot folder, though that could take some time as there are (a lot) of DLL’s that would have to be copied, plus that makes an all around messy folder. Unsure if it would work, as I said I currently don’t own a 64 bit machine.

      I’m thinking of using a getOSType() function on form load to determine your OS version, then after that it should just be a few line changes.

      There may be a disadvantage to that though, the only thing being a slower startup time.

      September 4, 2010 at 7:55 pm

  4. Running x64 here.

    I was able to get everything to work great by copying iTunesMobileDevice.dll into C:\Program Files\Common Files\Apple\Mobile Device Support\ manually.

    I think the fix would only require you checking in Program Files (x86) for the dll too or have the user copy the dll into the correct path.

      Thanks for that tip! I had to go to another site to download iTunesMobileDevice.dll, but it was well worth it. I was almost scared I was going to brick my phone before I even tried jailbreaking.

    It would appear that mediafire.com is down. Not sure if this is temporary or not. Do you use any other file sharing site?

    I can’t seem to get this program to work.

    I have a 3GS 3.1.2 which has a tethered jailbreak to blackra1n. It randomly got stuck in some sort of “recovery mode loop”(maybe due to one of cydia’s updates?) and will not start up. It just goes straight to recovery mode no matter what jailbreaking software I use to get it out. I have been looking online for a solution for 2 days now and nothing has worked. It seems like the only option is to use iTunes restore which would force me to lose all my files and be stuck with 4.0.2

    I tried this program last night. In the program it says “no device in recovery mode found!”. Even though itunes logo is on the screen and iTunes announces “this iphone is in recovery mode… etc” when plugged in. So I choose “enter recovery mode”, it says the iphone should be in recovery mode. I choose “exit recovery mode”, it says my iPhone should be normal now. No combination of choices actually do anything to my iPhone though. Any ideas on what is happening?

    Any help would be super appreciated.

    • iHacker

      The recovery detection feature ONLY works if you have libusb win32 installed.

      You may be in DFU Mode, and not recovery mode (though iTunes lies and says it’s in recovery mode). Install libusb (assuming you don’t have it), see if RecBoot can recognize your device. If not, RecBoot isn’t the application for you.

      September 9, 2010 at 9:51 pm

    I’ve already downloaded NET Framework v4.0 3x and repaired it twice. But every time I bring up Recboot I get a prompt that says
    “Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. Access to the path is denied”
    I’ve clicked continue, and proceed to click “Exit Recovery Mode” and it doesn’t do anything. I’m at a standstill, what do I do?

      If your on a 64 bit machine, RecBoot won’t work for you.

      September 9, 2010 at 9:48 pm

    • Moe

      You have to right click on the recboot application (color blue) and run as aministrator.

      September 18, 2010 at 8:37 pm

      • Tara

        This was the missing link Moe!!! On windows 7 machine (circa 8-2010) – right click and run as administrator worked PERFECT. Iphone downgraded and set to go!

      • Eric

        You just ended a 10-hr search for other software similar to RecBoot to fix my problem (since RecBoot wasn’t working). I kept running into unhandled exception errors until i ran recboot as an administrator.

    Montana is dead on!!! Copying the dll file made RecBoot work on my 64 bit machine! Super easy fix! Montana is my hero!

    pls advise.. Thx!

    September 10, 2010 at 11:39 am

      Well, you obviously need to install .NET 4.0.

    It said “The procedure entry point CFCopyDescription could not be located in the dynamic link library QTMLClient.”

    I installed Quicktime 7.6 and used WinXP.
    How to fix this problem?

    Hey man, thanks for the response.

    I just downloaded libusb win32 and tried everything out on our XP 32bit computer. RecBoot now recognizes the device is in recovery mode, but selecting to kick it out of recovery mode results in the command prompt saying “recovery_connect_callback recovery_disconnect_callback” over and over while the iPhone keeps restarting into recovery mode.

    Any ideas or should I call it quits and just restore?

    September 10, 2010 at 8:22 pm

    • iHacker

      RecBoot isn’t for you then, so try restoring.

      September 11, 2010 at 1:25 am

    For 64x bit windows 7 machines: very easy, google (download iTunesMobileDevice.dll) download it and place to ( C:\Program Files\Common Files\Apple\Mobile Device Support ).

    Run RecBoot, exit recovery mode. All works :)

    September 11, 2010 at 2:22 am

    • Dave

      Worked perfectly, with the exception that I had to exit recovery mode 3 times and then it worked and I was prompted to restore a backup in iTunes! Thanks!!

    For those who cannot get RecBoot work on x64 systems there is a very easy way to make it work: Just copy and paste all the content of the paste C:\Program Files\Common Files\Apple\Apple Application Support to the paste where is the RecBoot. Copy and paste. Copy and use RecBoot. Copy and DOWNGRADE! XD!

    September 11, 2010 at 4:47 am

      confirmed working on 64x, tried everything else and nada but Marcelo’s fix worked great!!! Thanks

    Totally Awesome.
    RecBoot is a great app. Worked great on my new iPhone 4g 4.0.2 “MC” version using Windows XP Pro. I was stuck on recovery mode for hours while trying to jailbreak it. This app ended recovery mode is about 10 seconds and all was back to normal!
    Thanks

    PS Still waiting for jailbreak!

    I cannot thank you enough for your great work. I was ready to pull out my OLD Nokia because my 3g was completely useless. Your assistance, when both Apple, and AT&T refused to help, is greatly appreciated.

    it wont work on my winxp x64… i tried copying the latest itunes iTunesMobileDevice.dll & using the older version…. luckily i still have my old 1.1 recboot

    September 12, 2010 at 1:44 pm

  22. Seth

    I downloaded everything and saved shsh files, went through restore and when i booted recboot up (ran as admin) I got the message saying “Unhandled exception has occured in your application. if you click Continue, that application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

    Cannot create a new file when that file already exists.”

    I hit continue and it brings the error up again. Also said no device found in recovery mode. Does this mean I will not be able to downgrade OS?

    Instead of downgrading , can i use your tool to upgrade from 3.1.2 to 4.0.1.

    this way i skip the upgrade process of the lastest firmware 4.1…

    September 13, 2010 at 7:05 pm

      Last update, i did my upgrade of 3.1.2 to 4.0.1 by simply doing a shift+restore off itunes and picked the 4.0.1 i had downloaded previously.

      Hi Sxr001,

      Copy all of what files in “C:\Program Files\Common Files\Apple\Apple Application Support”?

      Do you mean copy all the files from

      to

      C:\Program Files\Common Files\Apple\Apple Application Support

    http://www.iphone-hacks.com/download.php?id=46

    If you’re on 64 bit, just unzip that into C:\Program Files\Common Files\Apple\Mobile Device Support

    Run as administrator, and you’re done. :)

    September 26, 2010 at 3:51 am

  33. bokko

    Running Windows 7 64bit.

    First like others have said copy iTunesMobileDevice.dll from C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\ manually to C:\Program Files\Common Files\Apple\Mobile Device Support\

    Then when I ran it I started recieving further errors pointing to missing files from Apple Application Support. So I think copying the entire x86 directory will get messy could cause furture problems. So instead I just extracted recboot and it’s files into C:\Program Files (x86)\Common Files\Apple\Apple Application Support. Got myself out of recovery mode then when done deleted the recboot files from the directory to clean up.
    I do not have LubUSB installed just iTunes 9.2.1.5…(for x64)
    Ihacker I think you can safely say that if you detect x64 OS and point program to respective directories it should be fine. Yes I had .Net 4.0 installed already.

  43. Win 7 64bit
    .NET 4 installed
    UAC off (otherwise right-click and run as admin for all programs)
    iTunes 9.2
    iPhone 3G (4.0FW)
    Firmware downloads – http://www.iclarified.com/entry/index.php?enid=750

    Open iTunes with iPhone connected in recovery mode. Click OK/Check. Hold down the shift key and click Restore. Navigate to and select the chosen firmware (I used 3.1.3 3G). Click OK. After a few minutes, ERROR **** (don’t worry)

    LibUSB-Win32 – http://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.2.0/libusb-win32-bin-1.2.2.0.zip/download?use_mirror=netcologne
    Create a folder on your desktop. Run inf-wizard.exe from the bin folder with iPhone connected and turned on. Click next, select your iPhone from the list, click next. Save to the folder located on the desktop.
    Open this folder and run installer_x64.exe. Other than the brief appearance of a CMD window there is no evidence of successful install but windows beeped to let me know a device had been connected and the screen lit back up (driver refresh for iPhone).

    Open a CMD window and paste this “copy C:\Program files (x86)\Common Files\Apple\Mobile Device Support\
    iTunesMobileDevice.dll C:\Program files (x86)\Common Files\Apple\Mobile Device Support\” (without quotes)

    RecBoot 1.3 – http://www.mediafire.com/?x2xkfrlz7ibjleb (same link as original poster/author)
    Run RecBoot.exe. On my system RecBoot still reported ‘no device in recovery mode found’. Click exit recovery mode. iPhone automatically disconnects/reconnects. My iPhone came back on in recovery mode and just as I was rerunning installer_x64.exe the phone switched to normal mode. :)

    I’ve rebooted the phone a few times and installed a couple of apps to make sure everything is working. No problems so far.

    I hope this helps someone.

    I’m trying to download RecBoot v1.3 so I can downgrade my iPhone 3G, but after it downloads, I get an error messages that says “This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.” Please advise what to do. I’m on a Vista 32-bit system. Thanks.

    running on windows XP PRO x64… yes the old one

    see comment from:

    For 64x bit windows 7 machines: very easy, google (download iTunesMobileDevice.dll) download it and place to ( C:\Program Files\Common Files\Apple\Mobile Device Support )…..

    Download RecBoot zip extract to a ‘new folder’…. right click ‘.exe’ run as administrator… (deselect the box ‘run with limitations’) leave that up… I plugged in an un-powered iPhone4 ver. 4.0.2 … opened iTunes… and then hit exit recovery mode on RecBoot… working… presently installing ver. 4.1

    Hey,

    I was wondering if you could add support for the “special DFU” mode by Dev-Team, as currently there is no Windows software that enables that. Therefore, Windows users are unable to load PwnageTool custom images created on a Mac.

    See:
    “FU button: That “DFU” button in PwnageTool is more than it looks like. It guides you through the DFU process, but then also runs the appropriate exploit to convince your device and iTunes that all is legit. The DFU button in PwnageTool is not just your average DFU.”

    Thanks !

      Since I’m not part of the dev team, I unfortunately do not have access to the “exploit” mentioned in that post. Sorry!

        Actually I saw they released an new version of RedSn0w that allows that, if someone else asks …

    THIS IS HOW TO GET IT DONE ON WINDOWS 7 x64!!!

    1) run recboot, you may get error messages saying “continue” or “close”, well, just search google for “iTunesMobileDevice.dll” and find a download link to it, then transfer the itunesmobiledevice.dll to C:\Program Files\Common Files\Apple\Mobile Device Support

    2) NOW run recboot and it should run nicely and allow you to exit recorvey mode and now back to whatever firmware you downgraded to.

    hope this helps, if it does, please help others in life also. kbye.

    SCREW YOU APPLE.

    When I try to open RecBoot, I get an error message that says “Microsoft .NET Framework. Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. Access to the path is denied.” What should I do from here?

    “ping” posted on September 10, 2010 at 2:16 pm

    I open RecBoot and click “Enter Recovery Mode”
    Error says “The procedure entry point CFCopyDescription could not be located in the dynamic link library QTMLClient.”

    I am using Windows Vista dot net version 4.0 is installed.
    I am using recboot version 1.3
    I have an iphone 3G and want to restore to version 3.1.3 from version 4.0

    Thanks

    RecBoot would recognize my iPhone 3gs (firmware 4.0.1) as being in recovery mode, but when I click for it to kick me out, a black box just pops up and constantly resets my iPhone, still being stuck in recovery mode. :(

    Hi, nice & works, although it’s useless to help jailbreaking since it provides just recovery mode not dfu mode … hmmm. Any ideas?

    I need something to help with dfu since my 3g ( ios 4.2.1 refuses to enter dfu with any of the “press & release buttons” routines

    I am running windows 7 64bit version. I just copied the “itunesmobiledevice.dll” that is in the recboot directory once you decompress the file and copied it to C:\Program Files\Common Files\Apple\Mobile Device Support

    It worked perfectly. :)

    I need help! I am computer-tarded and trying hard to
    downgrade my phone(I had a oospie moment and accidently upgraded
    it..) I went through steps with my itunes and got the recboot
    downloaded and everything. then when I open it is says “Unhandled
    exception has occured in your application.” what does that mean?
    When i hit continue it takes me there but it never actually does
    anything. Just says “your device is entering recovery mode.” for
    forever and stays! Help!!! if anyone understands what I’m talking
    about please help.

      @Bart

      For recovery detection to work you need to install LibUSB.

      You must also run RecBoot as an Administrator for it to run properly.

    Hey, thanks for the great utility :) So I’m having a bit of a problem…
    my iPod Touch 2G MC is in recovery mode and I have RecBoot working and everything (I’m on Windows 7 64-bit) but when I click Exit Recovery, my iPod will start to boot up normally but stop and go back to booting into recovery mode. Have any suggestions?
    I really don’t want to restore because I installed a bunch of third party apps since my last backup :| Hope someone can help :D

    January 27, 2011 at 8:33 pm

    Excellent idea. Unfortunately, on perhaps seven attempts, get error that halts the downgrading at last step. Here are the speceifics — appreciate you:

    (Running XP, 32-bit far as I know (several years’ old Dell 8400 and XP w/SP2). I wanna downgrade iPhone 3G to 3.1.3.

    Have installed .NET 4.0 (and when that on its own failed to do the job here, also installed .NET 2 and 3).

    I’ve installed libsub as administrator.)

    1. But the process at the end reaches this message:

    The iPhone could not be restored. An unknown error occurred.

    2. As the administrator we run Recboot.

    Message of error appears:

    Microsoft netframework An unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. Could not find iPHUCWIN32.exe

    3. I click on Continue; I click Exit recovery mode, but Recboot’s message says

    unhandled exception has occurred in your application, If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. File not found

    (Am pasting the details into end of this note, after the dotted line).

    4. I click on Continue, and get message that sez your device is not exiting recovery mode, but it just sits there.

    5 I get outta iTunes’ pop-up box from before, and get

    itunes searches and explains

    iTunes has detected an iPhone in recovery mode. You must restore thei iPhone before it can be used with iTunes.

    Meanwhile Recboot still is tell you Your device is exiting recovery mode.

    But it just hangs.

    What are we doing wrong?

    Hi there,

    man, you saved my life!!! =D
    With RecBoot I could fix my iPad (iOS 3.2.1, jailbroken with JailBreakMe) stucking at the loading ring infinitely after a respring (maybe caused by SBSettings).

    For starting RecBoot I hadn’t to copy any files (using iTunes 10.1.2 on Win7 Ultimate x86 with .netFramework installed), but just running it with admin-privileges.

    It would be great if you could look through sebby’s source at https://github.com/the0rkus/RecBoot-for-Mac and add/update if there’s something new.

    Keep up the good work :D
