I have AT&T (enough said there) and so I am trying to update to 10.2 with Sanchesi but the Install isn't getting past 50% on the first file. I'm not sure if I'm even using a compatible carrier (T-mobile), though I am using the correct country code for the US.
My post is via the CB10 app. I'm rocking the leaked beta OS 10.3. Early build. Not for everyone. If you restore your data and are OK with setting up your accounts all over again I would suggest using the autoloader for 10.2.1.2234. It wipes your device so If you are afraid of losing crucial data go the sachesi route. I've never gone the sachesi route.
