Upgrade Problem

[muznybozz]

I have an iPhone 4S unlocked by a gevey sim. When i try to update it to ios 6.1.3 it shows the error (-1)
whats the reason???
Jailbroken in iOS 5.1.1
now its showing recovery loop.
Plzz reply

probably because your gevey does not support the newer firmware youre trying to upgrade to, plus if you are jailbroken and trying to upgrade over the air that will be your problem..

you will have to plug your iphone into itunes but make sure 6.1.3 is supported first, if not then stay on that firmware

If it's a GSM network you're attempting to use it with, it'll be compatible. CDMA networks stop at iOS 5.1.1.
