Known issues
- Flash fails on both system and user partition due to there not being enough space, use a micro sd card or try making a smaller system image if you have this issue.
- Audio not working right now, hoping to fix soon.
- No Hardware Acceleration!
- Framebuffer locked to portrait mode (could probably be fixed by rotating it in the xorg config)
Mainlining
Partially boots using Nexus 7 Grouper's dtb and shows up in dmesg. Do not attempt! Not responsible for device bricking! You have been warned!!
