Sunxitools Windows Portable — Top & Complete

Since "SunxiTools" is not a single official executable but rather a suite of tools (most notably sunxi-fel), a "Windows Portable" version usually consists of compiled binaries that you run from the Command Prompt.

Here is a text put together explaining what it is and how to use the portable version on Windows.

Step 3: Entering FEL Mode

To use SunxiTools, your device must be in FEL mode (USB Boot mode). sunxitools windows portable

  1. Power off your device.
  2. Locate the FEL button (usually hidden near the USB port or under a sticker).
  3. Hold the FEL button while plugging the USB cable into your PC.
  4. Windows should make the "device connected" sound. Check Device Manager to see if an "Allwinner Device" is listed.

4. Disk Imaging on the Go

Create a full sector-by-sector backup of a failing hard drive to an external disk. This feature alone makes SunxiTools portable worth its weight in gold.

Why a Portable Windows Version?

  1. No Administrator Rights Required : Run directly from a USB stick, SD card, or local folder. Perfect for field technicians or lab PCs with locked permissions.
  2. Self-Contained : Bundled with necessary drivers (usually libusb or Zadig) and dependencies, so you don’t hunt for missing DLLs.
  3. Same Commands as Linux : The Windows port uses identical command-line syntax to the Linux version, making cross-platform documentation easy to follow.

What is SunxiTools?

Originally a command-line utility for Linux, SunxiTools is a collection of tools designed to interact with Allwinner SoC devices. It allows you to do things that the official manufacturer tools often make difficult, such as: Since "SunxiTools" is not a single official executable

  • FEL Mode Flashing: Interacting with the device in FEL mode (USB Boot mode).
  • NAND/NOR Management: Reading and writing to the onboard NAND or SPI flash.
  • Partition Handling: managing partitions without fully booting the OS.

The Windows Portable version brings this power to your desktop without the need for complex installations or large framework dependencies.

What is Sunxi-tools?

Sunxi-tools is an open-source collection of low-level utilities designed specifically for Allwinner ARM processors. Key tools include: Step 3: Entering FEL Mode To use SunxiTools,

  • sunxi-fel : The most important utility. It communicates with the chip’s FEL (Forced Entry Loader) mode, allowing you to upload code, read/write memory, and execute custom bootloaders on a “bricked” device.
  • sunxi-nand-image / sunxi-nand-part : Tools for creating and managing NAND flash images.
  • phoenix-info : Reads information from Allwinner devices in FEL mode (e.g., chip ID, DRAM size).

On Linux, you would compile these from source or install via apt. On Windows, a native build is rare – but a portable version exists, eliminating installation, registry changes, and dependency headaches.

Portable Windows Version

A Windows portable build of sunxi-tools does not require installation – you can run it from a USB drive or any folder.
Available tools include:

  • sunxi-fel.exe – Communicate with device in FEL mode over USB
  • sunxi-nand-image-builder.exe
  • sunxi-bootinfo.exe
  • sunxi-fexc.exe – FEX script compiler for display settings

Case 2: The Office Lockdown

Your corporate laptop has Group Policy blocking all .exe installations. But your critical presentation is gone from the recycle bin. SunxiTools Portable runs directly from your USB stick without triggering any installer restrictions. You recover the file and save your job.
