We'll soon have an Android 6.0 firmware for T8 Mini owners that are happy to test beta releases. We will be releasing this to individual devices where the owner has indicated they want access via the OTA application.
Please see https://droidbox.co.uk/how-to/how-to-find-your-droidbox-android-mini-pcs-device-id/ for details on how to extract the information we'll need.
If you're not comfortable installing non-official firmware, or don't have the time to report back with any issues found, please wait for an official release (OFFICIAL releases will not require ANY information from you, you can disregard the post above).
If you ARE interested, please post back in this thread confirming:
a) You have a DroidBOX T8 Mini
b) You understand the implications that a status of "Beta" on a firmware can bring
c) Your Android Device ID (if you have a preferred app to extract this, feel free to use that instead, the app in the blog post is a suggestion).
