1600 Error

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

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)

  1. Hello,

    I have this same error with a 4.0 OS. I already try anything for this posts, but at least nothing happens. My Iphone is a 3GS with a custom firmware unlocked with a snowbreeze. The phone was working fine and freeze when i have installed the winterboard. Now, nothing works and the iphone remains in initial screen (freezing apple!).

    Can you help me?

    Thanks a lot.

  2. hey!! . . i’ve got a 3GS with iOs 4 . . n is on emergency calls mode ! . . i cant activate the phone cauz i dont use at&t . . i tried to downgrade te firmware as well as restore a hacktivated version of iOs but while restoring 16xx error pops up . . what should i do??

    1. 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…

  3. Awesome.
    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.

    THANKS.

  11. Thanks….this worked, but you missing two steps. in a mac, make sure to delete the info in the carrier support as well as clearing/deleting the info in software update. after those two are clear, make sure to restore the computer/mac and then build the ipsw

  12. Wow, your second method worked for me like a treat. I just deleted Device Support File from "C:Documents and SettingsMeenuApplication DataApple ComputeriTunesDevice Support" and it click Restore in iTunes and it started in one go 🙂

  17. 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

  19. 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.

  20. 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.
