Unofficial SteamOS ARM Port 1.3 now updates through Steam, and a first beta reaches Snapdragon 865 handhelds

The community port went stable on three Snapdragon families on 7 October and pushed its first in-place update three days later. A Snapdragon 865 test build followed, not yet run on real hardware.

The Unofficial SteamOS ARM Port, a community project by the developer hashtagbasit that runs Steam's Game Mode and a KDE desktop on Android gaming handhelds, reached version 1.3 on 7 October. The release notes call it the first stable build for all three Snapdragon families the project supports: the 8 Elite (AYN Odin 3, KONKR Pocket FIT Elite), the 8 Gen 3 (KONKR Pocket FIT, AYANEO Pocket S2 and S2 Pro) and the 8 Gen 2 (AYN Odin 2, Mini, Portal and Thor, several AYANEO Pockets, and the Retroid Pocket 6 and Nova).

The port is rebased on the latest SteamOS ARM from the Steam Frame, version 0.5.3, with Mesa 26.2.3 and Gamescope 3.16.30. It is not made or endorsed by Valve, and every release page says so.

Flash once, then update from Settings

The biggest change is that 1.3 is meant to be the last full reflash. Settings, System, Check for updates now installs new versions in place. The notes say updates are signed, only carry what changed, and roll back if one fails. That was put to use on 10 October, when version 1.3.2 arrived through the updater with fixes for external screens over USB-C and HDMI, a Desktop Mode screen that stayed black after idling, and a Pocket S2 picture that filled only half the panel.

Version 1.3 also adds Loadout, a beta store for emulators, launchers and apps, which includes an ARM64 build of Heroic so Epic, GOG and Amazon games can be installed from Game Mode. Sleep now uses real suspend on every chip, with Wi-Fi reconnecting in about a second. Steam's own TDP, charge limit and bypass charging controls work, and the system can be moved from the microSD card to internal storage with Android kept alongside it, though the notes say that is still untested on the 8 Elite.

The 865 beta, and the bootloader risk

A first test build for Snapdragon 865 devices followed on 10 October, one image for the Retroid Pocket 5, Pocket Flip 2, Pocket Mini and Mini V2, the AYN Thor Lite, the MANGMI Air Y Pro and Pocket Max, and the AYANEO Pocket MICRO 2. The developer is plain about its state: "I don't own any of these so it hasn't been run on real hardware yet."

Every install depends on replacing part of the device's bootloader, the ABL, with the one from ROCKNIX. The project's ABL guide warns that flashing the wrong chip's ABL can leave a device unable to start. Its script backs up the stock ABL before writing, and the guide asks owners to copy those backups to a PC. For the 865 build, that means flashing a bootloader onto hardware the image has never booted on.

Lenovo's Legion Y700 Gen 3 and Gen 4 tablets are listed as in testing. The developer's post on 8 October says those need an unlocked bootloader and a willingness to wipe Android's data.
