Allwinner A23 Firmware Exclusive May 2026

Developing a new feature for Allwinner A23 firmware typically involves modifying the Android system (if using the original SDK) or working with the mainline Linux kernel. Depending on your technical goal, you can approach development in three main ways: 1. Modifying the Official SDK

The Allwinner A23 SDK is split into two primary components: Android and Lichee (which contains the kernel and bootloader) .

Kernel Features: To add low-level features (like a new sensor driver), you must modify the source code in lichee/linux-3.4 .

Build Process: Use the build.sh script in the lichee directory to compile the kernel and rootfs, then use the pack tools to create a flashable .img file . 2. High-Level Firmware Modification (No Source)

If you don't have the source code but want to add apps or change system behaviors (like startup animations or default settings):

DragonFace: This is an official Allwinner tool used to modify .img firmware files. It allows you to inject apps and modify the system configuration script (sys_config.fex) without full recompilation . allwinner a23 firmware

Firmware Kitchens: Tools like the "kitchen" suite can be used to unpack existing firmware images, modify the partitions (like /system), and repack them . 3. Mainline Linux Development

For developers wanting a modern environment instead of the dated Android 4.4/Kernel 3.4 stack:

Linux-Sunxi Project: You can use the Mainline Kernel which supports the A23. This is ideal if your "feature" is a Linux-based application or a standard hardware driver .

U-Boot: The bootloader for the A23 is open-source and part of the sunxi-based systems support, allowing for early-boot feature development . Key Development Resources

Hardware Reference: Consult the Allwinner A23 User Manual for register maps and SoC specifications . Developing a new feature for Allwinner A23 firmware

Flashing Tools: Use PhoenixSuit or LiveSuit to push your developed firmware to the device over USB .

Part 1: What is Allwinner A23 Firmware?

In simple terms, firmware is the low-level software that makes your device’s hardware function. For an Allwinner A23 tablet, the firmware package typically includes:

Unlike popular devices from Samsung or Lenovo, Allwinner A23 devices are almost always white-label tablets—manufactured by unknown Chinese companies and rebranded under names like "Prestigio," "Digma," "Sunstech," or no brand at all. This makes firmware hunting a challenge. Part 1: What is Allwinner A23 Firmware

Part 3: Critical Step – Identify Your Device Before Downloading

Before you download any "Allwinner A23 firmware," understand this: There is no single firmware for Allwinner A23. Each device has a unique combination of:

Using firmware with mismatched drivers causes: inverted touch, white screen, no Wi-Fi, or a bricked device.

Replace kernel

# Compile kernel from sunxi-3.4 (legacy) or mainline (experimental)
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig
make zImage dtbs
# Combine with U-Boot header
mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux" -d zImage uImage

Part 7: Common Errors and Their Fixes

| Error | Likely Cause | Solution | |-------|--------------|----------| | "Device not found" | Wrong FEL button or bad cable | Try all hardware buttons. Use a short, high-quality USB cable. | | "Invalid firmware image" | Image corrupted or for wrong SoC | Redownload. Ensure it’s for A23 (not A20, A33, or A64). | | Error 0x163 (USB timeout) | Driver conflict or USB port | Disable driver signature enforcement on Win 8/10. Use USB 2.0 port. | | Stuck at 7% or 94% | NAND flash incompatibility | Your firmware has wrong NAND driver. Find a different dump. | | Touchscreen reversed/not working | Wrong touch driver | You need firmware from the exact same PCB revision. | | Wi-Fi won't turn on | Incorrect wifi module | Search for a firmware that lists your Wi-Fi chip (e.g., RTL8723BS). |

How to Identify Your Exact Firmware Version:

  1. Look at the sticker on the back casing – Often reveals a model number (e.g., Q88, M709, V66).
  2. Check the "About Tablet" section – If the device still boots: Settings → About Tablet → Build Number.
  3. Open the device (physical inspection) – Remove the back cover (carefully), find the PCB, and look for a silkscreened code like A23-Q88-V1.5 20150820.
  4. Connect to PC without powering on – Use PhoenixSuit; sometimes it detects the device version.

Pro tip: Search the numbers from the PCB or build number on Google or Chinese forums (4PDA, XDA-Developers, FreakTab).
