Quoting ikjtel ikj1234i@yahoo.com:
This is not about an issue with the connection, there was, and eventually led to the Pi being replaced as faulty or melted down from use of OP25 :) ;)
I too had a bricked PI - suspect that it was due to my omission -- failure to install the 2 heatsinks. Could you please confirm whether or not your failed PI had the heatsinks installed...
NO HEATSINKS.
The new one does, and actually I am putting it and others in a case(s) WITH FAN(S).
USB ports seem to be "warm" as well.
