Unfortunately there isn’t a one-click patch to resolve the error 50 problem on iTunes since the problem is not actually caused by a bug inside iTunes. It’s either with the internet connection or some network settings on a router or a computer which blocks iTunes from connecting to the Apple servers. One of the methods below should work for you: 1. Try Other USB Port - Disconnect the device from the current usb port and connect it to other usb port. Wait for iTunes to detect the device and try to restore it. 2. Re-install iTunes - iTunes could have been installed on your computer with a faulty network settings, or files may could get corrupted as well. Re-installing iTunes would solve all these troubles, it is advised that you download the latest iTunes version from Apple’s website and install it. 3. Check Firewall/Antivirus Settings: Many firewalls or antivirus programs would block any incoming or outgoing traffic via a suspicious program. Unless defined otherwise, iTunes is not supposed to be listed as a suspicious program but user might still check the blocked software list, just in case. iTunes shouldn’t be in the barred list in order to work properly. 4. Clean Registry – Registry could be a major reason why iTunes show error 50. iTunes registry on Windows OS could go wrong about the settings, or might just get corrupt and result in showing Error 50. In such a case, all other fixes might prove worthless. 5. Check Network Connection – Check router settings, whether it’s blocking any port that iTunes uses. Similarly, check if any similar blocking settings are applied on your computer. Sim Card problem - Just remove the sim card from the device and try to restore it via iTunes without sim card. Baseband problem - If you used GEVEY sim before, your baseband chip need to be replaced.
