Here is a simple trick you can use to Bypass that dreaded iTunes error 1600 on your iPod touch, iPhone, or iPad. This will work with any 16xx error, such as error 1601, 1602, 1603 and 1604. For those of you who want to know why your encountering this error, its because the device wasn’t properly put in DFU mode when attempting to have iTunes restore the custom ipsw with the device.
For Mac users we are going to use redsn0w to fix this problem and enter our device into a pwned DFU mode that will work when we restore our custom ipsw with iTunes.
For windows users use iH8Sn0w’s iReb RC4. It is very simple to use and will work like a charm for all 16xx errors. However you can use Redsn0w as well and a link to download it is below.
But iReb doesn’t currently work for Mac. But luckily we can fix this iTunes error with Redsn0w anyway and it just takes a minute.
First open up Redsn0w, and select your stock ipsw. NOT the custom ipsw made with Pwnage Tool, Redsn0w won’t recognize it.
Download Redsn0w for Mac
Download Redsn0w for Win
Once you’ve done that press Next and it will process the ipsw. Again press next until you get to the screen below. Instead of clicking install Cydia, press Just boot into tethered DFU mode right now.
(****NOTE**** If your Jailbreaking your device on 4.3.2, 4.2.8 or below, you can just check install Cydia now and jailbreak it at this point right now without having to use your custom ipsw fyi. But that isn’t always the case.)
Then turn off your device and press next…
Then follow the prompt to put your device into DFU mode.
It will say finished and then your good to open up iTunes and restore your iDevice with your custom ipsw.
And voila that’s all there is too it. To see a short video of how to do this check it out below.
