I ran the latest update last night (28th June 2017) and my Pi 3 has been unable to boot since.
The red LED (power) is on and that's all, the green LED does not even blink, no HDMI signal.
At first I thought it might be the 16GB SD card, but looking at the card in Windows all that is on it are 3 txt files and OracleLicence. Seemed strange as I've been using it and downloading programs for 6 months.
So, I formatted and burned the latest image on a new 16GB SD card. In Windows it lists a stack of files including
Kernel7. I Popped this in the Pi, the red LED is on, the Green LED blinks 2.5 times and it booted as far as
Kernel Panic (179,2).
Also tried this new SD card in a different Pi 3 with the same results.
Is there something wrong with this latest update?
