Okay, I used the "reloaded" fonts and got the loop on a system I tried the exploit with. I read everything on these forums about the looping and tried every method that was listed (no matter how silly they sounded). I left the Xbox on for 6 hours straight...on 3 occasions. NOTHING.
However, I didn't give up. Tonight, while I was playing some Diablo 2, I turned away from my computer monitor for a second and saw the Evox screen on my tv!!!!!!!!!!!!
What did I do? I simply left the system on...for about 2 hours straight, Ethernet cable plugged in, no disc inside, a controller in the first port. Does any of that matter? Probably not. However, leaving your Xbox on and rebooting, and having lots of patience seems to get it out of the loop. That's what I kept reading over and over, and that's what fixed it for me...well, for now anyway. I haven't unplugged it since. I'm using Bigfonts25 now. Let's see what happens when I unplug it tonight!
