Fix iTunes Error 1600, 1601, 1604 During Custom Firmware Restore

My iPhone was useless for almost two days before I finally fixed this error and got my phone working again. I was trying to restore a custom iOS 6.1.2 firmware created with Sn0wbreeze but couldn’t do it because iTunes kept throwing up all sort of error messages. Sometimes, I would get Error 1600, 1601, 1604 or something similar. I use Windows 8 on my laptop and thought maybe my iTunes was messed up or something due to the various jailbreak tools I’ve used on it. I tried restoring using my old desktop computer running Windows XP but it was still the same thing.

I had no problem restoring the phone using a stock iOS 6.1.2 IPSW but whenever I tried using the custom firmware created through Sn0wbreeze, I couldn’t get past this annoying error. My phone was stuck at “Preparing iPhone for restore” for minutes. I had no choice but to restore using a custom firmware because my phone relies on hacktivation to be of any use.

I finally fixed this error using a tool I never thought would work because I’ve tried all sort of things already but but it did work and I was able to restore using the custom firmware created with Sn0wbreeze.

1. Close iTunes and all other programs that may communicate with your iPhone


2. Download iReb.

3. Unzip the content and run the .exe file contained in it.

4. Click on your phone model from the list

5. You will be asked to get your phone into DFU mode. In case you don’t know what it is, follow these steps:

  • With USB connected, make sure your phone if fully turned off
  • Press and hold power button for 3 seconds
  • Without releasing the power button, press the home key too and hold both buttons for the next 10 seconds
  • Now, release the power button but keep holding the home key for about 12 or 13 more seconds

6. When iREB detects your phone is now in DFU mode, it does what it has to do and sets your phone in PWNED DFU mode.

In this mode, you can now launch iTunes and try restoring again with the same custom firmware created with Sn0wbreeze you were trying to use. I bet it should work. It’s how I finally got rid of of that error 1600 thingy.

  • sometimes while updating the firmware of the ios device iTunes get the error because due to some technical issue some files get deleted so you have to update the itunes support to use it again

  • Have an Apple Ipod 2G 2.2.1..Has got an update 4.2.1..Would like to update to 4.2.1.
    But can't update.
    When trying with original It gives error...(-1)..!!!!
    Pls help me !!!!!!!

    • Error -1 is not something I'm sure I've seen before but if I may ask, are you using the latest version of iTunes?

  • I am in DFU mode (iReb) trying to restore 6.1.2 still getting the 1601 error on Custom firmware (snowbreeze) and Stock firmware.
    The device is on 4.1 and doesn't require unlock.
    Changed cables, Changed OS, and 3 PC - still No luck.
    Any ideas?

      • You're correct 6.1.2 is no longer signed by apple, and due to a Major cydia failure most SHSH blobs were deleted.
        The client doesn't mind using a Tethered Jailbreak so i went for 6.1.3 (with shsh blobs so that downgrade would be possible.)

        iBooty on PC is now required to boot the device, I tried using SemiTether by Bigboss but i think that only works if Jailbreak was done with redsn0w (6.1.3 + 6.0 + Old boot rom)
        Now i see why you haven't mentioned 6.1.3 in any recent blog post :p

        • Actually, I gave my iDevice our a few weeks ago but I intend to get another one soon. Stuck with Android at the moment. :)
