Maybe I should make one thing clear:
The player works perfectly for normal usage.
Playing, Uploading via Ethernet, etc.

I can see the output on the serial port (boot info, etc)

Updated info:
It looks like the player won't receive anything via the serial port.
(No upgrade, no (j)emplode, no shell)
Just switched cables and PCs to connect, no differenct.

Maybe I fried the RX of the serial port somehow while putting in the new power connector last week....


And to answer your question:
It never finds the player; And I powercycled it aounrd 30 times so far....
