Sunxitools Windows Portable Direct

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: Test the Connection

Run:

sunxi-fel.exe version

If successful, you’ll see output like: sunxitools windows portable

If you get “No FEL device found”, check your driver and cable.

What it is

SunxiTools (also called sunxi-tools) is a collection of utilities for Allwinner ARM SoCs (the "sunxi" family). It includes tools for working with bootloaders, extracting and repacking firmware, dumping and writing flash memory, converting images, and inspecting device partitions and metadata. A Windows Portable build packages these utilities so they run on Windows without installation.

Case 1: The Accidental Format

You just formatted your external 2TB drive containing years of family photos. Panic sets in. You download SunxiTools Portable on a friend’s laptop, run it, select “Partition Recovery,” and scan. Within 20 minutes, the old partition table is restored. No software installation touched your corrupted drive.
