I have this tablet...........model tm1318 android 4.4.4 build rk3188-eng4.4.4 ktu84q eng.cyf.20150227.143052 test-keys I am trying to get this tablet rooted and have a custom ROM installed. It is running KitKat 4.4.4 and I am having trouble staying connected with the Bluetooth. I keep getting a popup saying "Unfortunately Bluetooth Share has stopped". I understand that KitKat has a problem with Bluetooth so I would like to upgrade the tablet to Lollipop. Can anyone here help me out?
