The RG CubeXX is an Allwinner H700 handheld whose official firmware ships as a disk image (.img) you write to the TF1 (OS) microSD with a normal tool such as balenaEtcher or Rufus; there is no full-OS over-the-air updater. Recent public stock builds are in the V1.0.x range on the Anbernic download portal. Re-imaging TF1 does not touch the TF2 card that holds your ROMs and saves, but back it up first. This is a DRAFT for human review.

FAQ

Which microSD does the firmware go on?
The TF1 (OS) slot. TF2 holds ROMs and saves and is not overwritten, but back it up first.
Is there an on-device updater?
No full-OS OTA. The reliable method is flashing the .img to TF1 with balenaEtcher or Rufus on a computer.
