Error 29 in iTunes when trying to restore the 4s to 9.2 version. It was stuck when I tried to update on air. Tried several times updating then restoring with Itunes. Updated Itunes, Mac, used DFU mode, restarted both machines, changed cable, changed USB. Nothing helps. I dont have an old battery, trowed it away when it stopped working...
BTW - Local Istore wanted to charge for restore, they dont even have 9.2 downloaded. It will take two hours with their slow connection. ***? They cant help.LOL.
