It’s mostly because we had a jailbroken i Phone that wasn’t restored to factory settings.
For starters, Apple isn’t all that interested in people downgrading their i OS firmware.
So naturally, all the signing is already done with so if you’re trying to downgrade to i OS 6.1.3 or lesser after an upgrade to i OS 7, you’re going to have a bad time.
Note #1: Tiny Umbrella and this method are actually part of the 3194 error fix for “downgrading” your i OS firmware.
But in some cases (like ours), it worked for an update too.
Don’t Miss: Transfer Songs from Computer to i Pod with/without i Tunes Sometimes fixing your i Tunes sync error (-54) seems a little difficult because it is hard to find which files cause this problem.
