As promised a long time ago, I would upload the Android 2.3 for the MiniX and MiniXPlus. Both the MiniX and Mele version are available for download. Android 2.3 might be old, but it runs much better and cooler than 4.x versions. It’s on the firmware page, let me know if there are any issues.
For the Allwinner A10S the standard 1.6 firmware is also online. As I do not have a box with A10S chipset I cannot test it.
