💻 What Are ArkOS and OnionOS?

The R36S ships with stock firmware that works but leaves performance on the table. ArkOS and OnionOS are custom firmware (CFW) alternatives that unlock the full power of the R36S hardware. Both are free, open-source, and community-developed. The difference is in philosophy: ArkOS prioritizes raw performance and customization; OnionOS prioritizes ease of use and a clean interface.

⚠️ Important: ArkOS and OnionOS are designed for different hardware. ArkOS is optimized for RK3326-based devices like the R36S. OnionOS was originally built for Miyoo Mini but has been ported to other devices. Always download from official sources and verify your device compatibility before flashing.
