Title: Reverse Engineering and Custom ROM Development for the Allwinner H616 Platform

Abstract:
The Allwinner H616 is a cost-effective, 64-bit ARM Cortex-A53 quad-core processor widely used in low-cost Android TV boxes (e.g., Orange Pi Zero 2, Transpeed, X96 Mate). Despite its Linux mainline support, creating a fully functional custom Android ROM (e.g., LineageOS, AOSP) is obstructed by proprietary display drivers (Disp2), Mali G31 GPU blobs, and DRM encryption for HDMI. This paper outlines the hardware architecture, boot flow, vendor blob extraction, and the process of building a custom ROM using the hybrid approach of "stock vendor + AOSP system."

Forget the Chinese launcher. Community developers have ported the AOSP (Android Open Source Project) to the H616 with a Leanback Launcher. These builds strip out Google spyware where possible (or use microG) and optimize the RAM disk for video streaming. allwinner h616 custom rom

5.3 SELinux and Permissions

Stock H616 ROMs often run permissive SELinux. For custom ROM, set: DDR3 vs DDR4 RAM (timing tables differ)

) have been found with pre-installed malware and wide-open ADB ports.

Flashing Your Custom ROM

For SBCs (Orange Pi Zero 2):

  1. Write the built .img to an SD card using dd.
  2. Insert card, power on. U-Boot will auto-detect.
  1. BROM (mask ROM) reads from SD card, eMMC, or NAND.
  2. SPL (Secondary Program Loader) initializes DRAM.
  3. U-Boot (vendor-modified) loads from a partition (e.g., boot0, boot_package).
  4. Trusted Firmware-A (TF-A) for ARM TrustZone (optional).
  5. Linux kernel (vendor 5.4 or 5.10 with H616 patches).
  6. Android (system, vendor, odm partitions).
