Firstly, thanks so much for your help in explaining how to get this device rooted! Worked like a charm.
Now that the device is rooted, I would really like to install a pure Google Android version of Lollipop on a Vodacom Power Tab 10 (VF-1296).
The tablet already has Lollipop running but there are some features - like SIP calling - which have been disabled on the Vodacom Power Tab 10.
I'm not sure if this is relevant or not but I have found a file with the name VF-1296_20150915.tar.xz at the following link:
So my question is, is it possible to install a custom rom on this device and, if so, how would one go about it?
