Flashing bootloader from Arduino nano v3 to nano v3

After a long search I found this and it works:

Try this:

Approach A: (Arduino IDE/Arduino as ISP)

  • Open IDE
  • Tools >> Board >> Arduino Duemilanove 2009/Nano w/328
  • Tools >> Serial Port >> (choose correct one)
  • Upload the ArduinoISP sketch (Files >> Examples >> Arduino ISP) to your working NANO

(unplug your main/working Arduino Nano)

  • Wire up your 'target' board that is outlined in the tutorials (D11, D12, D13, +5v, GND & RESET) pins...

MAIN BOARD: >>> TARGET BOARD:
D10: >>> RESET
D11: >>> MOSI
D12: >>> MISO
D13: >>> SCK
GND: >>> GND
+5v: >>> +5v

  • Go to: Tools >> Board >> and choose ""Arduino Duemilanove 2009/Nano w/328"..

  • Tools > Burn Bootloader > w/ Arduino as ISP
