Hi, I would like to know from fellow users of Asus Fonepad 7 (K00Z model) who have made the firmware upgrade from default JellyBean to KitKat. Did you have to do a factory reset before upgrading? And what are the pros and cons after the upgrade?
Re: Network disabled in Fonepad 7 (K012)
Did you try disabling and re-enabling the SIM through the settings? It usually solves such issues. Otherwise, maybe doing a factory reset could be your only option.
