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
Revive "bricked" devices by loading a new bootloader.
Students and hobbyists working with Allwinner-based development boards find SunxiTools invaluable for learning embedded systems concepts. The ability to explore low-level hardware functionality through accessible command-line tools provides hands-on experience with real-world embedded development workflows.

To use sunxi-fel , you usually need to install a generic USB driver for your device using Zadig (select WinUSB or libusb-win32). Run via Command Line: Open a command prompt in that folder.
Windows does not natively recognize FEL mode. You must install a driver for the Allwinner device.
