Installing and Using OpenWrt
1

Hello.
I've tried to search with keyword, but can't find the case like mine.

I made common mistake. tried to change firmware without converter....
I bought USB-TTL converter with CP2102, tried to connect to RE650 via serial port.

but putty shows the screen like this

device flashed every seconds, so putty refreshes every seconds, too.
TX, RX, and GND are properly connected as the guide said.
I can't begin recovery process. It just doesn't give me a single change.

It my RE650 completely bricked? Is there anything I can try?

If you're seeing output (generally, even if unreadable) that usually indicates that there is something functioning.

This can commonly happen if you have one or more of the following mismatched:

  • voltages -- make sure your USB serial adapter uses/is set for the correct voltage. On many routers it is 3.3V TTL.
  • baud rate and connection parameters. Make sure Putty is configured for 57600 baud, 8N1.
  • Ground - make sure the ground connection is solid... a faulty connection to ground could cause this type of thing, too.

changed to 57600 and it worked!
