Developer tech4bot reverse-engineered the Doogee U10 Android tablet and produced a complete Debian 12 Bookworm image that boots from an SD card without unlocking the bootloader or touching internal storage. The project, called rkdebian, required zero vendor documentation — just a Rockchip RK3562 SoC, four Cortex-A53 cores at 2.0 GHz, 4GB of RAM, and an open-source build pipeline.

The image handles touchscreen, Wi-Fi, Bluetooth, audio, USB OTG, and even RK3562 NPU inference via Rockchip's RKLLM stack. Benchmarks on the tablet showed Qwen3-0.6B generating tokens at 24.9 per second on the NPU, outpacing Qwen2.5-1.5B at 2.18 tok/s. Cameras and 3D acceleration remain partial, but the core OS experience runs smoothly with Plasma Desktop and Flatpak support.

Building the image requires an x86-64 Linux host and runs via a single build.sh script that compiles U-Boot, kernel, and rootfs. No vendor BSP was used — the effort leaned on Claude, Codex, and Antigravity for development guidance. Pull the SD card and the tablet returns to stock Android, making this a risk-free way to run a Linux workstation on budget hardware.
