The RG35XX (2024) is an Allwinner H700 handheld whose official firmware ships as a disk image (.img) you write to the TF1 (OS) microSD with a normal imaging tool such as balenaEtcher or Rufus; there is no on-device updater. This model has no Wi-Fi or Bluetooth, so there is no online update package and no over-the-air option. Re-imaging TF1 does not touch the TF2 card that holds your ROMs and saves, but back it up first. Recent public stock builds are in the V1.2.x range on the Anbernic download portal. 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 a Wi-Fi update?
No. The RG35XX (2024) has no Wi-Fi or Bluetooth, so you must flash the .img to TF1 on a computer.
