Alright, the quick stats:
X2 Lite modchip
My friend scrounged up a free used modded Xbox with what the owner described as "a broken modchip."
Several years ago I was making pretty decent money with Xbox repair, and had several boxes of my own with XBMC for a cheap networked home-theater system. It was pretty rad, but I've gone about 4 years without having to open up an Xbox and I'm a little rusty on some of the details these days.
Anyway, I started with plugging the box in and turning it on, and was presented with error code 05 - unlocked hard drive. It was also making a loud buzzing noise, which turned out to be the GPU fan. I had a spare, so I quickly replaced that. Upon opening the box, I find that the wire to the bottom D0 point had gotten pinched between the motherboard and a standoff, smashing it flat.
Unfortunately, I made the mistake of not checking to see if it was still carrying a voltage. I immediately assumed the smashed wire kept the D0 from being grounded and thus didn't allow the modchip to override the BIOS, allowing the unlocked hard drive to present an error.
So, I replaced the smashed wire, plugged everything back in, and now the Xbox reboots twice before staying on, throwing up the flashing orange. Googling to refresh my memory on the color flash errors only presents me with "bad trace or solder splash." So, I check the voltage on the pin headers and D0 point, but they all check out fine.
When the modchip is disconnected, I get no error aside from the 05 code. With the modchip connected, I get the double reboot and flashing orange. Is the modchip physically damaged, or does it simply need a reflash? And if it is the latter, can i reflash the X2 Lite without any hardware aside from the Xbox and the modchip itself? (i.e. no BIOS bank selector control panels like the X3CE comes with.)
