: The primary tool used to interact with devices in FEL mode (a low-level boot mode for Allwinner chips) via USB. It is commonly used for: Retrieving device information. Reading or writing to memory (SRAM/DRAM). Booting a device over USB without needing an SD card.
Because the official sunxitools repository targets Linux, utilizing it portably on Windows requires a pre-compiled binary package paired with a universal USB driver handler. Step 1: Download the Portable Binaries
If you are trying to recover data from a corrupted device, you can dump the contents of the onboard storage directly to your computer: sunxi-fel.exe devinfo Use code with caution. Step 3: Unbricking and Flashing Firmware
Download the archive (usually .7z or .zip ). Right-click and select "Extract to SunxiTools_Portable\ ". Place this folder on your or a USB drive . Do not put it in Program Files to avoid permission issues. sunxitools windows portable
Unbrick dead devices by booting them directly into RAM via USB when the onboard storage is corrupted.
: Even though the tools are portable, you must still install a compatible USB driver (often using Zadig ) for Windows to recognize the Allwinner device in FEL mode.
Windows will fail to recognize the device in FEL mode by default. You must map it to a universal driver. : The primary tool used to interact with
: A specialized utility to repartition raw NAND flash chips directly on sunxi boards. Why Use the Portable Windows Version?
: You must install the Zadig driver (WinUSB) for your device while it is in FEL mode.
Click or Install Driver . Windows will now route the raw FEL connection directly to the Sunxitools binaries. Step 2: Essential Sunxi-FEL Command Guide Booting a device over USB without needing an SD card
While these tools are natively built for Linux, they are available for as portable binaries, allowing you to interact with hardware in FEL mode without a full installation. 🛠️ Key Utilities Included
For a purist, native Linux is faster and more stable. However, holds a distinct advantage for specific workflows:
