Have cheapy 7in chinese alps mid tablet (no boos and hisses please, poor oap)). I have managed to root it via SRS. I have a file manager, superuser, updater, titanium back up with access therefore to miui , cyanogen and aokp. I cant find custom rom from any of these sources. What do i have to do to upgrade the OS from ICS 4.0.4 to jelly bean or kit kat. I am not a techy and would have to be classed as a dummy and talked through any instructions step by step. Thanks Edward
