These devices are still young products which receive frequent firmware updates, that are usually delivered thru incremental OTA (Other The Air) packages, downloaded thru WiFI on the “Update” application. Another update path that is specially useful for a Factory reset and full firmware image flash using Allwinner PhoenixSuit custom Windows application. This tutorial will explain the different steps to successfully flash a tablet based on Allwinner A31 processor.
