Error 13 and 14 : Are checksum problems with the firmware image that is in the update package.
The update package is a .ipsw (IPod or IPhone SoftWare). This file is actually just a .zip renamed .ipsw.
The error is caused by a failure to download a crc-free version of the file. Not really sure why there are so many crc problems with the iphone updates, but Apple does not check the integrity of the update package before wiping your current version of IPhone software and that is why all IPhones that start an update with a bad update package end up in recovery mode. These errors are NOT related to the iTunes installation, antivirus software, or firewalls.
Recommendation : use a program like "Object Fix" (Freeware) to verify the integrity of the file prior to commencing with any new updates. You will have to keep trying to download it until you get a error free file. Once you have a CRC error free file this problem will go away. (I thought TCP/IP helped get rid of CRC errors.)
I had another problem and that was...
Error 1603 and 1604 : These are USB driver connectivity problems.
Recommendation : FULLY uninstall and re-install itunes software as stated in the Apple support documentation. Be sure to reboot between each step and these problems should clear themselves up. In addition, firewalls and anti-virus software may cause these errors as well.
Finally, shame on apple for not properly documenting their software so that end users do not have to decrypt their error messages with no true support to solve the issues. These are problems that enough people have had that there should be specific documentation on these problems.HP HDX 16t, Windows Vista, 64-bit

Thanks for the heads up on the error 14 CRC problems. I downloaded object fix and discovered that my ipsw's were indeed bad. Got new download...now all is well.
Thank for the good work and for sharing.iPhone 3GS, iPhone OS 3.0
