Use a hex editor to patch updater.exe yourself (NOP the CRC jump). This is advanced but cleaner than trusting a pre-patched binary.
Error: "Device not in upgrade mode"
→ Re-enter recovery mode (hold reset during power-on). Try different LAN ports (use port 1).
Error: "File too large"
→ The W300 flash is only 4MB or 8MB. Use a firmware smaller than 3.8MB.
Tool crashes or antivirus deletes it
→ The patched binary modifies memory of the original updater. This is safe if downloaded from a trusted source. Add an exclusion in Defender.
Router is bricked (no LEDs, no ping)
→ You need a USB-to-TTL serial adapter (3.3V). Solder to J2 header (RX/TX/GND) and interrupt CFE boot to flash via TFTP.
