Hi all,
I've been working with Arduino Unos for a couple of years now, and I recently decided I wanted to try the Nano V3.0; however, I had troubles with it from the get-go. There were errors on the IDE that I don't remember, but it doesn't matter at the moment because the base point is that the Nano didn't run sketches, and I thought it was bricked. The LED still blinked intermittently, though.
After doing some research, I thought that the bootloader was to blame, and I tried to reinstall it using an Arduino Uno as an ISP interpreter. That, too, has not worked for me to date. I have tried modifying the efuse value for the Nano from 0x05 to 0xFD in the boards.txt file to get rid of a warning, but that did nothing to solve the problem. I also found a cheap CH340 USB-to-Serial chip on the Nano, so I made sure to install that driver.
I am running Arduino 1.6.8 on a Windows 10 64-bit OS. The Nano shows up in my devices as a USB-SERIAL CH340, despite my attempts to install/reinstall the CH340 driver. When I try to upload the bootloader to it through my Uno, the IDE returns this error message:
