| Goal | Feasibility | Effort | |-------------------------------|-------------|--------| | Debloat stock Android | ✅ High | Low | | Upgrade to AOSP 8/9 | ❌ Nearly impossible (no HALs) | Extreme | | Install mainline Linux | ✅ Stable | Medium | | Run modern Android (TV) | ⚠️ Partial (Android TV 12 GSI fails) | High | | Hardware-accelerated Kodi | ✅ Yes (LibreELEC) | Low |
Recommendation: If you want a modern OS on RK3229, do not fight Android. Use LibreELEC (media center) or Armbian (headless server). For true Android custom ROM development, invest in RK3588 or Amlogic S905X4 hardware.
