.At some point I needed to re-flash the Tinyboot loader on my old faithful Plus1. I believe that, I was on the 5 volts pin (Should have put my glasses on!) instead of the 3.3 when I touched the little gold pad in front of Digital 0.
Anyway, since then, when I power it, the blue Led stays on and it does not communicate with the PC.
Is there anything I could do to revive it, or is it definitely dead?
Thanks for your help,
Bernard.
