Updating from v1.4.0

  • Already on v1.4.0? The OTA update brings v1.4.1 straight to your device. No reflash and no data wipe needed.
  • New to GammaOS, or on an older build? Download the v1.4.1 package below and flash it as usual (this is a clean install and will wipe data).

This is a whole new GammaOS

v1.4 is not an incremental update. On the RG Rotate, GammaOS Nano is the primary UI (https://thegammasqueeze.github.io/GammaOSNano-WIKI), and it is not a launcher, it is a whole micro-OS built on top of Android. It grabs the panel the instant you power on and paints a full console-style home, but underneath it is deeply integrated with the low-level Android system and the device hardware: DRM-direct rendering straight to the panel, an early-boot audio engine that sounds before the rest of the system is even up, native power and sleep management, and direct control of the panel and the slide sensor. There is no heavy Android launcher loading in the background, no bloat, and no waiting. It boots straight to a console-style experience that is fast, lean and built for a controller first.

The RG Rotate ships with the full GammaOS Next underneath, so you are never locked in: you can switch freely between GammaOS Nano and the full GammaOS Next Android experience whenever you like.

Linux support has moved

Linux support is no longer part of the GammaOS image. It now lives in its own repository, maintained by Noxwell (Beebono):

To run Linux on the RG Rotate, use the latest release and SPL flasher from that repository. You do not need GammaOS to run Linux. Please report any Linux issues there, not on the official ROCKNIX channels.

Known Issues

  • DraStic RetroAchievements currently supports Softcore mode only. Hardcore mode is pending approval from the RetroAchievements team, which can take up to around 6 months if they agree to it.

What's New

For the full list of changes in v1.4.1, see the changelog:
https://github.com/TheGammaSqueeze/GammaOSNext/wiki/GammaOS-Next-Changelog#v141-august-2026

GammaOS Nano gives you three complete home themes (DSi System Menu, PS3 XMB and Minima) that you can switch between at any time, a much-improved built-in DraStic-nano DS player with RetroAchievements (Softcore) and Quick Resume, the RG Rotate slide mechanism as a first-class control (rotate, sleep/wake, launch an app, or summon the PSP-style Clock UI when you slide the screen shut), custom and looping video wallpapers, an in-game overlay on a power-button hold, reworked sleep and wake, and self-contained music, video and photo players, a controller-first web browser, IPTV and Internet Radio, system-wide Network Shares (SMB/NFS/WebDAV/FTP) and a global search. Both flavors boot into GammaOS Nano as the primary UI and let you switch to the full GammaOS Next Android experience at any time.

Before You Download

This release comes in two flavors. Both boot into GammaOS Nano as the primary UI and let you switch to the full GammaOS Next Android experience freely. Pick the one you want:

  • Full - includes Google Play Store, Google Play Services and Google sign-in, for people who rely on account sync and Play Store apps.
  • Lite - ships without Google Services for the leanest, cleanest boot-to-play experience, ideal if you sideload or use alternative stores.

Download the package

Each flavor ships as its own split archive. Download every part of the flavor you want:

Full (with Google Services):

  • ums512_1h10_rg_rotate_gammaos_1.4.1_full.7z.001
  • ums512_1h10_rg_rotate_gammaos_1.4.1_full.7z.002

Lite (no Google Services):

  • ums512_1h10_rg_rotate_gammaos_1.4.1_lite.7z.001

Also download the flashing tools:

  • UnisocTools_RG_ROTATE.zip

Extract

Extract all parts of your chosen flavor together (right-click the .001 while the other parts are in the same folder and extract, using the password from Patreon). You will get a single .pac file to flash.

Install

Installation is the same process as before. Full installation steps are available here:
https://github.com/TheGammaSqueeze/GammaOSNext/wiki/GammaOS-Next-Installation#anbernic-rg-rotate

Note: Installing will wipe all data. Back up your device first.
Remove any microSD card before flashing to avoid issues.
If you are already on v1.4.0, you do not need to reflash - the OTA update brings v1.4.1 to your device.

Overview

GammaOS Nano v1.4.1 is a ground-up rebuild of the RG Rotate experience, based on Android 14 / LineageOS 21, in Full (with Google Services) and Lite (without) flavors. Rather than loading a heavy Android launcher, it boots straight into a native, console-style home built for handhelds, with the full GammaOS Next Android experience one switch away. This release focuses on a fast boot-to-play experience, three full home themes, a much-improved DraStic DS player with RetroAchievements, the slide mechanism with its PSP-style Clock UI, and custom and video wallpapers. Linux support now lives in its own repository (https://github.com/beebono/distribution/releases).
