plug the iphone to your computer (make sure you have itunes installed in your computer) turn the iphone off once plugged. Once its turned off, press the power button and the home button at the same time, hold it for around 10 seconds but continue holding the home button. on your computer (itunes) it should show up a message detecting the device (iphone) just press ok and it will bring you to your itunes home screen--from there CLICK "RESTORE" and that will enable your iphone again :)

Download the latest iTunes to your computer and reset the iPhone. Then re-sync it.

Reset

If your using a MAC try the below steps as this worked for me:

1. User - Library - Prefrences - com.apple.iTunes.plist
2. Delete that com.apple.iTunes.plist
3. Restart the computer. It should recognise.

If your using a PC the steps are lengthy, and the steps are:

Restore I-Phone
1) Close all programs and restart computer.
2) Open iTunes and plug in powered off iPhone with direct USB connection.
3) If iTunes fails to connect to iPhone...continue to #4, if it does...restore.
4) Shut DOWN iTunes again.
5) Power OFF the iPhone & Disconnect from computer. (Power off two ways-one will work, hold home and sleep button until off or just hold sleep button until off)
6) Hold down Home button & connect to computer using direct connected USB cable (keep holding down the home button until iTunes sees it).
7) It should go into recovery mode and iTunes should recognise it.
8) If you want to recover to previous software version, Hold Alt/Shift and click restore in iTunes. Then select the old update version.

If the above steps doesnot work then try the below steps:

1. Turn the iPhone ON
2. CONNECT it to the computer with a DIRECT USB connection.
3. Make sure iTunes is open so you'll know when it enters DFU mode.
4. HOLD the Power/Sleep-Wake button AND the Home button for 10 seconds.
5. RELEASE only the Power/Sleep-Wake button and continue to hold the Home button.
6. WAIT until iTunes recognizes the phone in DFU Restore mode (in Windows a bubble pops up saying it recognized new hardware "DFU Mode" or something to that effect)
The last step may take SOME TIME, like, say, even 60 seconds or so.
The screen should be OFF (black), if you see the "Connect to iTunes" logo, START OVER.
It may take a few tries to do the steps just right, just reboot
(hold both Power/Sleep-Wake AND Home until the Apple logo appears and the phone turns back on) then try again.
7. Then restore the iphone

-Plug one end of the cord into your phone and the other in your computer
-Remove the cord in your computer, leaving the cord in the phone still plugged in
-Hold both the home button and on/off button on the phone
-Once the screen turns off, let go of the on/off button but continue holding the home button
-Plug in the other end of the cord in your computer while still holding the home button on the phone
-Once the apple logo appears, continue holding until you see the plug into itunes screen on your phone
-Click restore.

Hope this should resolve your issue :)

press and hold the power button and the home button together for 10-15 seconds till you see an apple logo re appear on the screen. If that does not work, power down the phone, press and hold the home button and connect it to your computer. Once you see the message in iTunes that an iphone has been detected in recovery mode let go of the home button and restore your phone

connect to pc , switch off the iphone , hold down power button and home button for 10 seconds exactly ,leave power button and keep on holding home button until itunes detect after that update the iphone

Have you tried doing a hard reset, Holding down both the home button on the bottom face of the phone and the on/off switch on the top left of the phone. Holding both those buttons down for about ten seconds will cause the iphone to restart and give you an apple symbol. when you get the apple symbol you can release those buttons.

Try each of the following resets:

Download the latest iTunes to your computer and reset the iPhone. Then re-sync it.

There are a lot of suggested solutions on different forums for the 1604 (including on the Apple support site) - most blame a faulty / corrupted itunes and suggest reinstalling, or blame the USB port you're using and suggest either trying a different port (ideally at the back of your HD) or different computer. None of those things worked for me when it happened to me. My issue was that the 'preparing to restore' phase of restoration became looped and eventually it crashed citing error 1604.

However, there was a solution at: http://daggle.com/iphone-upgrade-fail-701 which did work for me.

For convenience:

1. Start the restore process (whatever way you can).

2. When it seems to be stuck in the loop (and possibly your iPhone just shows a blank screen) use CTRL+ALT+DEL and end task to kill the iTunes application.

3. Restart the restore process.

First do the following : hold down the Power and Home buttons until you see the Apple logo, then release BOTH buttons, allow phone to boot, hold down the Power and Home until you see the Apple logo, then release BOTH buttons, your iPhone should now work right, if not, than do the following:

WARNING: restoring your iPhone cant take some time!

Follow these steps, yes they work I've had to do this twice now.

NOTE: You need to be plugged up to your computer for this to work

1. Hold down the POWER and HOME buttons untils your phone reboots.

2. Hold POWER button until the iPhone powers OFF

3. Hold POWER and HOME buttons, iPhone will now power on.

4. When you see the apple logo, release the POWER button but keep holding the home button.

5. iTunes should alert you now saying that it has found an iPhone in recovery mode, proceed to recover as normal now.

Also the iPhone screen may go white after doing this until restored, this is normal, it's not broken.
