The process of updating a T5.3.19 MCU is not without its significant challenges.
A: This is a common question, but the answer is almost always no . The hardware limitations of the Allwinner T3 platform (particularly the 1GB of RAM on some models) make a major Android version jump impractical and often impossible without a complete hardware swap. The system version is tightly coupled to the MCU; you cannot simply install a newer Android ROM without the corresponding MCU support.
In EU research projects:
