Here’s a full technical write-up on creating and updating a custom ROM for the Allwinner H616 (used in boards like Orange Pi Zero 2, Banana Pi M2 Zero, etc.), covering boot flow, partition layout, build environment, and safe update methods.




On your Windows PC, you need to install the Allwinner ADB Drivers. This allows the computer to recognize the box when it is in "FEL Mode" (flash mode). For Android custom ROMs, additional partitions: system ,


sunxi-fel write 0x40000000 update_Image
sunxi-fel write 0x41000000 update_dtb
sunxi-fel write 0x42000000 update.tar.gz
sunxi-fel exec 0x40000000 -- tar -C / -xzf /dev/mem? # (simplified)

The H616 does not have a physical "Reset" button that works for flashing 100% of the time. You must force it into FEL Mode.

  • The Short:
  • Result: PhoenixSuit will pop up "Found New Device" -> Press "Yes".

    • No pop-up? Try the AV port method: Insert a toothpick into the AV jack to press the hidden button inside while plugging in USB power.
