RDOD (Red dot of death).
My Xbox 360 S will boot on without V&A and it will only show the green dot with no rings around it. After 5 - 20 seconds the green dot goes red, no rings around it.
I am unable to disassemble the Xbox as I do not have the proper tools. The only thing I have done to try to fix it was replace the hard drive, this didn't work. My friend told me to use the "towel trick," but wtf would the towel do?
