Modchip Works Only Some Of The Time, duox2 blue amd and xbox v 1.0 wire installation Options

[will123]

I am going to post this as a new topic because my problem is no longer removing solder from holes.


Just finished hard mod with v 1.0 duox2.

did wire install

when turn on by eject button the xbox boots fine
when turn on by on off button I see nothing on screen. the modchips red light does go on and off
The red green frag occurs. the fan stops and starts a few times.

the weired thing is: If I keep on turning on and off about 1/20 times i will get the purple evox logo. I get all excited that "its working but I cant get it to consistently boot from the chip"

Why does it only work occassionally?

If I wired the chip to the lpc then how do I flash it. the tutorials I read require removing chip from header and then placing back on while the box is on. if its wired its too hard to remove and replace.

To flash it it should be as easy as booting into Evox or another flash program and flashing either bank. I don't think the Duo X2 has flash protection, but I could be wrong.

ok great. I thought I had to remove and replace chip while xbox on to flash but I guess i was wrong.

You don't need to flash the chip. You're getting the Purple EvoX logo, that means the chip is already flashed. If the chip is white, it should have started with Cromwell Linux, if the chip is blue it came preflashed. When you get your soldering all lined out, you'll only need to install a dashboard and you'll be good to go.

You only need to flash the chip if the current bios doesn't have a feature that you want (ability to use large 137+GB HD's, VGA bios, etc). Don't flash the chip if you don't have to.

Like I said in the other post, go over each of your solder points again. Actually reflow each point, especially d0. Make sure you didn't splash solder anywhere, even a tiny tiny blotch can bridge points on the motherboard (its unlikely, but possible). Also, make sure you used the install tutorial for the v1.0 box. I can't remember if there is a different procedure for v1.0 versus v1.1-1.5, but double-check.

If you get the soldering finished, use Slayer's and report back what it says for the bios. More than likely you'll be good with what's already installed.

thanks.

so i resoldered everything. I cant get the little logo up again. just fragging. the reject starts the box just fine. I dont see that I have a problem with the d0 point but I am thinking of trying to solder it to the alternative point just to make sure. I guess I can do the multimeter thing also to let me know if I have some cracks in traces or other invisable things. can the multimeter be applied to the chip to help diagnose or only the lpc port?
