Solution : Error 1600 while trying to Restore to Custome iPhone firmware for 2G / 3G iPhone Jailbreak

18 September 2009 141 Comments

If you get a 1600 or 16xx error while trying to restore to a custom 3.1 firmware for iPhone 2G or 3G, try the following :
Try this first instead of entering DFU mode…for 3G
1)UNPLUG ur iphone and turn off
2)Open itunes
3) hold home as u plug in iphone and keep holding until u see itunes logo on ur iphone
4) then SHIFT+restore and locate the custom ipsw
and there u go! (thanks txccu2000).

If that didn’t work, then try the following :

  • Try rebooting both iPhone and PC/Mac.
  • Make sure the iPhone is in DFU mode.
  • On a Mac – BEFORE creating the custom ipsw, delete restore files found in ~/Library/iTunes/Device Support
  • On a PC – Delete device support files (restore files) in iTunes folder in the following locations
  • Windows 7 and Vista : C:/*UsersName*/AppData/Roaming/Apple Computer/iTunesDevice Support
  • Windows XP : C:/Documents and Settings/*UserName*/Application Data/Apple Computer/iTunes/Device Support
  • Try restoring to the custom firmware via iTunes by (shift+restore on Windows, Option + Restore on Mac)

  • Sotiris said:

    I deleted the device support files (restore files) in iTunes folder and still got the same error. Only when I reinstalled itunes finally I was able to restore my custom firmware. So if anyone has still problems try this. I hope I helped…

    The last step is to re-install iTunes. It works! 😀 Thanks Sotiris

    No need to uninstall iTunes! Just delete the restore files!

  • bluenautica said:

    This was the only way that worked for me, but, the backup process did not work, which gave me nothing but a 3.1 update and now I have to install all my apps/contacts/etc… not cool =/

  • iLikeMyiPhone said:

    Well, installing apps and contacts shouldn't be that difficult. If you want to restore backup, you can always do that anytime after it is jailbroken. Right click on your iPhone (iTunes left bar) and restore from backup!

  • Jack said:

    If people are still having trouble with error 1600, try this too:

    For Windows:
    After restarting, trying DFU and all the above, copy the custom .ipsw that you created into:
    # Windows 7 and Vista : C:/*UsersName*/AppData/Roaming/Apple Computer/iTunesDevice Support/
    # Windows XP : C:/Documents and Settings/*UserName*/Application Data/Apple Computer/iTunes/Device Support/

    Rename the custom .ipsw file as the same name as the file that is already in here, name differs but it should be similar to "x12220000_5_Recovery"

    Now, follow the DFU restore technique through iTunes, I stopped receiving the 1600 error when I tried this for the first time.

    My custom .ipsw was created on my Macintosh, but I did all of the above on the Windows side. I imagine the same method could be used on a Mac, just copy the .ipsw over the backup one inside of:
    ~/Library/iTunes/Device Support

    Good luck.

    Hey, I have a 2G phone, that I can't get to work with the firmware. I'm getting the 1600 error, everytime. I have uninstalled and reinstalled iTunes. I have done all these steps multiple times with the 1600 error as the result. I have even gone as far as to change the name of the ipsw file to the recovery file name as listed above and still, I get the 1600 error. Is there anyway for you to share the ipsw file that is created by a Mac, so that I can try that one? I have no access to a Mac computer. Please help, its been two weeks without my phone and I miss terribly.

  • iLikeMyiPhone said:

    So sorry to hear that. Did you try the DFU mode or Restore mode? Did you follow the solution here and what custom firmware did you use? I posted the custom firmware links for 2G iPhones too. It will definitely work.

  • Shanon said:

    I have put my phone in DFU Mode, how do I know if I did not successfully get my phone into DFU mode. I have watched the youtube video, and I believe I get my phone into DFU mode everytime. I did follow your solutions for the 2G. I use the firmware for 2G 3.1 Firmware for other carriers, since I use TMobile. I just tried all of it again and I got the 1600 error again. I'm using iTunes 9.0 and I am on Vista. I am at a loss now. I think my phone is wiped completely at this point. I don't care about what I lost, I just want to phone to work.

  • iLikeMyiPhone said:

    Ok, how about you try the Restore mode instead of DFU mode? The videos should detail both restore and dfu mode.

  • Shanon said:

    OH THANK GAWD!!! I tried restore mode and once that was finished, I followed your instructions (again) by putting the phone into DFU mode and it WORKED!! YOU ARE BRILLIANT!! I should have done the restore along time ago. Thank you!!! Thank you!!!

    I have IPhone 2G which i'm trying to upgrade to custom 3.1 (activated for other carriers). I'm using Itunes 9.0.1 and i got 1600 error while trying to load the FW. Now the device does not turn on. Every time i connect to the computer (XP) i get a pop-up on itunes that an iphone in recovery mode is connected. If i try to send the FW with holding "Shift" key it will start but will fail wuth 1600. I tried uninstalling the itunes and re-installing the itunes with no change…. 1600 again…. what can i do now? Please help….

  • iLikeMyiPhone said:

    Did you try the steps mentioned in the 3.1 firmware post (custom firmware?)? Put it in DFU mode and then do a restore. If not, try restore mode (you can find the videos)..

    2G iPhones have no problem with unlock so, even if something goes wrong, you don't have to worry much!

  • Jek said:

    Hi, I'm having problem in unlocking my iphone.

    I bought the iphone 3g 16gb at the auction recently. And activated is needed when switch on the iphone, which I didn't expected. I can't check the firmware n baseband version, but seller told me that the firmware is 3.1, n itunes shows tat my firmware was the latest one.

    First, i downloaded custom firmware 3.1 activated and try to restore in DFU mode. and i got 1601 error. refer to this page, deleted file in /devide support/, and also copied the custom firmware and renamed to "x12220000_5_Recovery". same error happened

    tried again in discovery mode, now it came out 1604 error.

    and then, i downloaded custom 3.1.2, itunes showed msg tat firmware is not suitable.

    I worked all in window XP.


  • Jek said:

    thanks for your reply.
    I did join the files. the file name was iPhone1_2_3.1_7C144_Custom_Restore.ipsw .
    I tried in both recovery mode n DFU mode.
    And now i can't kick out of both of that 2 modes.

  • iLikeMyiPhone said:

    Please follow my videos to kick them out of that mode. Check in videos section.

  • Jek said:

    I've go thru the videos.

    When I'm in recovery mode, i tried to kick out from it, it doesn't work. it goes back to recovery mode after the apple icon appeared.

    Then I switch off recovery mode, by pressing power n home button, and release it when the cable n itunes icon gone. And then I tried to switch it to DFU mode and it works. From there i tried to kick out, and it appear recovery mode after the apple icon appeared.
    I tried to restore the custom firmware in both 2 modes. In DFU modes, message shows 1601 error, and 1604 error for recovery mode.

    Is it means that I have no way to jailbreak it? should it restore my iphone by just clicking restore button. n it will update my firmware to 3.1.2, n try to install custom 3.1.2 ??

  • Jek said:

    Ya, I've followed all the solution guide stated here. no use to my iphone.
    I unable to check the firmware version on myself, seller told me was 3.1 when i bought it.

    Do you mean that they will update my baseband too if i restore my iphone by just clicking restore at itunes?

    Yes, everytime shows the same error

  • Kiran said:

    Try downloading 3.0.1 ipsw from Apple (look for link in downloads section) and then try restore to it directly. It has 4.26 baseband. Lets see if it works.

  • Jek said:

    I tried to restore with 3.0.1 ipsw from apple in both DFU n restore mode. now shows error 1015. checked apply website, normally appear when try to downgrade.

    any other way?

  • iLikeMyiPhone said:

    Thats a good error! Restore to the same firmware again and let me know.

  • Jek said:

    you meant restore with 3.0.1 ipsw from apple right? i tried twice. same error coming out

  • iLikeMyiPhone said:

    Ok, now try the custom firmware in restore mode.

  • Jek said:

    Hi, i was unable to restore with the way u gave.

    And i think I'm the lucky one. I had a iphone and I've cancelled the line n sold it.
    I was suddenly think that maybe I can activate my iphone will old sim card, and it did. and itunes able to restore firmware with my backup data in my pc. i made to jailbreak by using the same way. And now im working on unlocking it.

    Thank a lot dude, hope you have a good business on ebay.

  • Jek said:

    Thanks with your help too.

    I have any question, I just found out that my version is 3.0.1 and modem firmware was 05.11.07. is it means that I can't unlock my iphone? all i can do is just wait?

  • iLikeMyiPhone said:

    Yep, no unlock for now :( But you can try 3.1.2 with jailbreak if you want. If you are tethering, just remain on 3.0.1…

  • illogicthoughtz said:

    Hey, I was wondering if you can help me with something.

    I have DLed the Pwnage tool 3.1.4 and the custom 3.1.2 firmware. When i start the Tool, the firmware is not found by Pwnage. When i click to look for it manually…it tells me that "wrong bundle."

    I have also tried the custom 3.1.2 firmware and pressing Opt./restore on my Mac. At the end it told me there was an error (16xx, i believe) and my iphone 3g stated on a black screen afterwards. Suggestions please!!!

  • Paki said:

    u cant unlock or downgrade ur baseband.. unless u have the bootloader 5.08 or less.. use fuzzyband (in cydia) it help u know what is ur bootloader….

  • scotchtape20 said:

    HOLY CRAP it took me alot of time to get this working… here's what i did to make it work on my iPhone 3G (i got the error 1600 then 1601):

    – Deleted the recovery file found in C:/*UsersName*/AppData/Roaming/Apple Computer/iTunes/Device Support BUT i did not copy my custom firmware in there… left it empty

    – Turned iPhone off

    – Entered DFU mode… and in the part where you need to hold ONLY the home button, i hold it until the screen became WHITE (i dont know if its necessary, but it worked for me)

    – It automatically opened up iTunes (which it NEVER did before) and i SHIFT+Restored it with the custom firmware

    DONE! (takes time before the progress bar on the iPhone moves, but it will trust me)

    I would suggest you restore to Apple's stock firmware (3.1.2) and then use this firmware in Restore mode since you have an iPhone 2G!

  • Buzz said:

    You lucky.. I tried it aswell, with XP, on my 2g. But negative result.. When you put it in restore mode, do you use the custom restore file (with holding shift etc) or do you do the official restore from itunes? I have Vodafone as carrier (holland), I bought my phone in England. I keep getting error 1600… Help!!!!

  • iLikeMyiPhone said:

    You do the custom restore, not the official restore!

    Since you have a 2G iPhone, why not restore officially to 3.1.2 and then use blackra1n?

Got the 1600 then 1601 when I deleted the x12220000_5_Recovery file found in Device Support (Vista, used search function to search for AppData then you'll find RoamingApple ComputeriTunesDevice Support). My phone was in DFU mode, couldn't get it to do anything, I then copy the 3.1.2 custom firmware to iTunes Device Support folder, then renamed it to the x12220000_5_Recovery file. Click on restore in iTunes, took about 10 min. and it works except it's locked. I then used the Shift+Restore method to select downloaded 3.1.2 firmware and I unpluged the usb while it's rebooting, then the BootNeuter2.1 Flashing Basband screen came up, took couple min for 3.9 and 4.6 to be loaded. Then it rebooted itself. Done and working. Thanks to ilikemyiphone.com.

    Kiran, Know of any place that has all the 3.1.2 files where I can simply transfer from file on my pc to the phone? I was meesin around looking for answers and left the phone connected to a usb port. The phone vibated twice and goes in and out of connection every 5 minutes when I leave it plugged into usb,… vibrates twice then connects/disconnects.

    I can also use iphone explorer or iphone browser and see that all the original files are intact prior to me removing a wrong boot up file. Know of any 3.1.2 files I can get to try and insert with iphone explorer or the specific file/folder I messed up…?

    Was your 3GS ever jailbroken? Did you ever use Cydia on firmware 3.1.x? Did you store SHSH blobs? If yes to any of those – then we can activate/jailbreak using custom i)S 4 firmware.

    If not, we will have to wait for now or you may find someone with AT&T contract to activate…

    MAC Trick for error 1600 after 2G custom 3.1.3 upgrade failure:
    * Forget DFU.
    * Hold down HOME button & plug into USB port.
    * OPTION key + clicking RESTORE button.
    * Locate custom 3.1.3 firmware.
    And your custom pwnage firmware will begin restoring.

    simple just
    connect your iphone to your computer and press the dfu mode button configuration and it will start up.release all the buttons……after some time 6 seconds..just then again keep holding the home button until you see itunes connect logo.and then restore in that mode

  • Adam said:

    Second method worked like a charm!! … I had tried everything and had almost given up, thanks from http://www.UpWebHosting.com !!!

    Used this method to move an iPhone 4 running on 4.2.1 to 5.0.1 while preserving the baseband with a custom .ipsw. I run Mac OS X Snow Leopard. I kept getting an error that said "this device is not eligible for the build" and found information here: http://www.idownloadblog.com/2011/12/28/device-no… that helped me solve that problem. I had to go about the hard way and edit the host file rather than use tiny unmbrella as they suggest first. I went in and deleted the file found in ~/Library/iTunes/Device Support and my custom restore went through without a hitch. Sure wish I had found this two days ago.

  • Etude said:

    I don't have any of those directories mention in method 2 on either Windows 7 or Lion. What gives? I've tried this as well as other methods (Tinyumbrella, holding down Home and plugging in, moving the "C:Program Files (x86)Common FilesAppleApple Application Support" directory, etc) and nothing seems to work. I have an iPhone 4 with iOS 4.2.1 and 03.10.01 Baseband. I've looked everywhere I can and there doesn't seem to be an answer that works for me. There has to be a way or at least an explanation why it doesn't work.

    The iTunes errors may appear to any iPhone, iPod or iPad users due to various internal or external reasons. If you are unable to access your iPhone data after iTunes error then you can try iPhone data recovery tool that works very efficiently to recover iPhone data even from the iTunes backup.
