I have a xbox v1.0 that I've installed the Aladdin Live with programmer chip. When you boot to evox it locks up in the boot screen with a yellow light. If you try to boot normally it errors saying your xbox needs to be serviced error with a red light. Prior to installing the mod chip I had softmodded the xbox. So I don't know if that might be why or not. I tried putting the new hdd into the xbox to see if it was the hdd, but it did the same thing. If you have any ideas as to what it could be please post or if you have the same problem. I'm rechecking the solder points now. Thanks for any help.
