Button combo

POWER(boot from TF1)

Steps

  1. 1Back up your TF2 (ROM) card to a computer first.
  2. 2From anbernic.com, open the RG ARC-S Linux OS download (the official link is hosted on a file-share); unzip the .img.
  3. 3Flash it to the TF1 (OS) microSD with balenaEtcher (or format FAT32 and write with Rufus).
  4. 4Put TF1 back in the OS slot and TF2 in the ROM slot.

The RG ARC-S is a Rockchip RK3566 Linux handheld, not an H700, and its official firmware ships as a disk image (.img) you write to the TF1 (OS) microSD with balenaEtcher or Rufus; there is no on-device updater. The latest official Linux build is version 20240104-V12, and Anbernic distributes it through a file-share link on its system-update page rather than a direct download, so use the live link shown there. Re-imaging TF1 does not touch your TF2 ROM card, but back it up first. This is a DRAFT for human review.

FAQ

Where do I get the official firmware?
From the file-share link on Anbernic's system-update page; the current RG ARC-S Linux build is 20240104-V12. Write the .img to the TF1 card.
Is this an H700 device?
No. The RG ARC-S uses a Rockchip RK3566, so firmware and custom OS images must be the RK3566 versions, not H700 ones.
