I have 2 version 1.6 (probably 1.6b) xboxes. They both have the m8+ bios flashed to the second bank and the flashbios 3.03 flashed to the first bank on a Xecuter 2.6. They boot up just fine and are able to load anything, but after a certain period of time, maybe a half hour or 15 minutes, they both will shut off. Then if you try to turn either on, they will not boot up (I think they blink yellow/orange). If you wait a while, it will boot up again. When Avalaunch loads, it comes up with a screen saying "fixing invalid date setting". It does this all the time. I don't know what is causing it. This is causing me extreme stress. Please help me out if you know a fix or are having the same problem!!!!
