The xbox was working fine and then froze so i restarted it and got rrod. I thought it probably just needed a reflow but sometimes when i turn it on i get 4 green lights and then rrod and occasionally i have had the top right led light green and then go to rrod. Anyone know what might fix this or is it definitely in need of a reflow as I thought if your jtag wires were bad it would give you E79 error.
