Oh yeah bro I remember you....Actually I'm having prob with my PS activation and not using it since two months....There is one more member KILLERDONS (my cousin). I think he can make one sig for you...He is very good with sigs...
Can this be done to all motherboard revisions?
Yes, all motherboard revisions are vulnerable to this hack. But the dashboard update on August 10, 2009 patched this hack. Some consoles that were manufactured or refurbished around June/July already have the patch applied. Which is why some kernels are not vulnerable.
How do I know what kernel version I have?
In the dashboard go to System Settings>Console Settings then scroll down to System Info. Your kernel version is shown here. In this picture the 360 has the 8955 kernel applied. This example is not vulnerable.
