[AC Question]

So basically, the main gist of my problem is in the title. I've also tried going through kies to update the thing, but still it won't work. I have tried doing it both over my home wifi connection and strong 4G, and still absolutely nothing. My phone IS rooted, but I'm pretty sure I did it correctly since I have no other problems other than registering/updating my phone. I have an I-747, factory unlocked. If anyone has any advice as to what to do in this situation, any videos or tutorials or just something more helpful than "did you turn it off and on again" it'd be much appreciated.

(tl;dr: rooted, factory unlocked I-747 SG3 has 'processing failed' message every time i try to update/register it. wifi/4g/kies = no change and a complete waste of my time.)

Please help. Thanks in advance.
