To get around this problem, there is a handy little tool called iREB
(iTunes Restore Error Bypasser) for Windows which can help you bypass
the error when you are restoring .ipsw file in iTunes. The latest
version of this program works with [You must be registered and logged in to see this link.] firmware running on the original iPhone, iPhone 3G and iPod touch 1G/2G.
Follow the steps below to bypass this error so that you can restore iPhone 3.1.3 firmware in iTunes.
Step 1: Start [You must be registered and logged in to see this link.] and put your phone into DFU mode:
Press and hold the Home button and the Power button at the same time.
After exactly 10 seconds release the Power button. Continue holding the
home button until you iTunes pops up a message telling you that it has
detected an iPhone in recovery mode. At this point your iPhone/iPod
touch screen will remain black.

Step 3: Simply select your device and wait for a few seconds until you get white or a red screen on your iPhone or iPod touch.
Step 4:
Now open iTunes and select your phone from the sidebar in iTunes. Now
press and hold left “alt” button (“Shift” button on Windows) on the
keyboard and then click on “Restore” (Not “Update”) button in the
iTunes and then release the “Shift” button. Select a custom .ipsw file
and restore it.
That’s it! iTunes should now be able to restore your iPhone or iPod
touch to the latest iPhone 3.1.3 firmware without any problems.
Hopefully you wont get any errors this time around!
