I did another test, with another conclusion and a solution theory.
After letting my box reboot for 10mins without the network cable plugged in, i decided to try it connected to my network, but without Internet Connection Sharing enabled.
The console booted up first go, this proves that having a network connected to the xbox (even if its got no internet access) helps with the clock loop problem.
The date was automatically set to 4th July as im using Bigfonts, after re-enabling internet connection sharing, the date and time set themselves correctly.
NOW HERES MY THEORY
Is it possible to make a network cable that will fool the xbox into thinking its connected to to a network, thus slowing down the boot process and allowing the fonts to kick in before the clock set page.
Is this possible by joining wires at the end of a network cable??
Apart from connecting new connectors to the end of cables, im not really in the know on how networks work, what info gets send down which wire etc..
But surely a simple crossover of wires could fool the xbox long enough, so people without a network can bypass the clock loop.
Any ideas, suggestions welcome.
