Accidentally flashed Rambo 1.0 f/w on Rambo 1.3 - Recovery?
So I did something really dumb last night, and accidentally flashed the 1.0 firmware image for my MK2.5 onto my Rambo 1.3 board. I did so using the OctoPrint / AVRdude firmware updater, so there were no checks to prevent this from happening. Since then, as long as my printer is turned on, the beep / alarm sounds and the LCD only lights up with two lines full of squares. Is there any way that I can recover from this? Or is the only solution a new board?

Just reflash. Direct connect to PC with Slic3r PR's flash tool if need. Tone is because of error in pin assignment difference between 1.0 and 1.3 only, USB assignment is the same as I know. This is not a irreparable error.

Ha, wow, I can't believe it was that simple. Thanks. I was assuming since nothing was showing on the LCD that the USB connection wouldn't even initialize, but yeah it flashed fine.
Now I feel doubly stupid.

Hehe, it is OK. Sorry for the scare.
