Finding the Kernel Version:
In the dashboard go to System Settings then go to Console Settings then scroll down to System Info.

Kernel Vulnerability:

8xxx and Higher - Any console with a kernel 8xxx and higher have been patched to stop the hack.

7371 and lower - Any console with the 7371 kernel or a lower version of the kernel are most likely vulnerable to the hack.(Explained Below)

Kernels 7357/7363/7371
These 3 Kernels wierd kernels. Some contain a patched CB which makes the console un-exploitable.

How do I know if my console has the patched CB?

1. If the console manufacture date is BEFORE 6-1-2009 then you can JTAG it.
2. If the console manufacture date is AFTER 6-1-2009 then it has the patched CB.

These pictures are to identify the motherboard.
