I have updated my Advent Vega tablet with the r8-vega-update-modacocustomtom-unsigned, and everything works fine apart from the Wi-Fi whatever I try it just comes back with an error. I tried erasing all content & settings (under the software tool) but still nothing. Bluetooth works Ok but no Wi-Fi, just an immediate error every time I select the Wi-Fi. Not sure if Airplane Mode was there before, but also tried turning that on and off, still nothing. I have a little knowledge of windows but not a lot of Android system knowledge.
