Safety and warnings

• These tools operate at low-level (flash memory, boot sectors). Mistakes can brick devices.
• Always backup existing firmware before writing.
• Ensure you have the correct target files for your specific Allwinner SoC and board.
• Use FEL and flashing commands only on devices you own or are authorized to modify.

Step 2: Enter FEL Mode on Your Device

FEL mode is not automatic. You need to force it:

• For development boards (NanoPi, OrangePi): Hold the "FEL" or "UBOOT" button while connecting the USB OTG port to your PC.
• For Android TV boxes (Beelink, MXQ, etc.): Short the NAND pins (often pins 29-30 on the H3 chip) or press a hidden micro-switch inside the AV port.
• Indicator: The device will power on but show nothing on HDMI. Windows will make a "USB connect" sound.

Important notes

• Requires libusb driver (Zadig can install WinUSB driver for Allwinner FEL device).
• No admin rights needed for most FEL commands, but driver installation requires admin once.
• Works on Windows 7/8/10/11 (32/64-bit).

Cons

• No context menu integration (you cannot right-click a drive in Explorer—you must open the tool first).
• Limited auto-update (you must manually download new versions).
• Some antivirus false positives (portable hacking/recovery tools often trigger heuristics; add an exception).

3. Multi-File System Support

Whether your drive is formatted as NTFS, FAT32, exFAT, HFS+ (Mac), or Ext4 (Linux), the portable version maintains full read/write capability for recovery. SunxiTools Windows Portable — Complete Content Safety and
