I have a v.1.6 Xbox and have installed a Xecuter 2.6. First time I soldered everything up and put the DVD and HD back in Xbox and found that whether I have the modchip enabled or not the xbox would boot to Xbox Dashboard. After many fusterating hours, I desoldered everything and started all over again. Installed pin header, then installed LPC rebuild, and finished up with soldering the HD and Lan points. I then tested without DVD and HD in and found that whether I have the mod enabled or not, it will boot up then give me service number 7 kernel - HDD timeout, and then frag to red and green alternating lights. I tested with every switch possibility , mod chip light and all switch lights are working fine. Can anyone help me with this most fusterating of mod installs I have experienced.
