Process of elimination?

[Bullet1979]

Ok... so I've overcome one problem and I think another... but I still haven't been able to get my xbox to load other than with the chip disabled.

The problem with the reset adapter not working was that there were two points soldered together behind the adhesive. I see that there are a lot of people with this problem so maybe that should be added to the stickies.

Now, I'm pretty damn sure my d0 is in the right spot as well, but my xbox still does the fragging twice then staying on with the red/green. Only reason I'm making another topic now is because every time someone has this, they're told to check their d0 and I've become convinced that my d0 is in the right spot.

So my question is (assuming it's a bad solder for one of the points on the pin header).... can I determine which points are bad by process of elimination? Both blue LED's on the chip light up... so does that mean that a few of the points are good? And if so... which ones?

I can now start my xbox with the chip in and disabled by holding the power button for a second while booting on but I get the 2x frag problem if I tap the power or eject button to power up. Before, I would have to remove the chip altogether to get the system to load M$. Although that surely could have had to do with my problem with the adapter.

I've got a multimeter and I'd love to use it to make my job easier but I have NO CLUE as to how to check the pin header solder joints, nor do I know which setting to put the multimeter on or where to put the leads. Even though I'm pretty sure that my d0 is now in the correct spot, can that be confirmed with a multimeter as well? Before I read that I just put the black lead on a ground and put the red lead on what I wanted to test... thought it'd be easy... but apparently that's wrong. Can anyone help me in any of these situations? I'd love to start making more progress!

Anyone? Anything?

describe more, on the stages when you try to boot with the chip enabled.

does the backup bios work? (press eject+power at the same time)

maybe someone can help you then.

 

[Bullet1979]

When I try to boot with the chip enabled, I get the classic "turns on and off 2 times and on the 3rd time, stays on and flashes red/green." This happens when I start up any way other than with the chip disabled (holding the power button for a second). Also, the led for HDD on the external switch shows activity, but not the LED for LAN... I don't know if that's of any significance but I'm just mentioning anything I notice.

My next approach I'm going to try is soldering wires to the LPC points and the other end to the end of the track corresponding to each point. Only thing is I'm having a horrible time getting the wire to solder to the points on the board... it just doesn't want to stick.

Have you been able to enter FlashBios and flash the chip?
What Version of the xbox do you have?

what happens when you press and hold eject+power button for a second?

The X on the memory module should light up white and Flashbios should be loaded. If this works we may have located the problem.

I had a similar FRAG earlier today, same symptoms, the reason was that i had flashed the bios with wrong bios file by a mistake.

 

[Bullet1979]

No I can do nothing but start the xbox with the chip disabled. Trying to turn it on any other way leads to the fragging twice and red/green on the third boot.

Also, the X on the external chip is ALWAYS red, no matter how I start the xbox.

 

[rasgal]

what happens if you start the xbox with only the eject button?

 

[Bullet1979]

Same thing... frag x 2 then red/green on third boot.

 

[rasgal]

ok, :idea: my head says there still is some error with your connections chip/ the soldering.
Go over it all again, take your time, don't be hasty and look closely. cross check with the guide, be sure that you follow the guide for your xbox version(v1.0-1.5 or v1.6).

 

[Bullet1979]

My Xbox is v1.6. I'd love to be able to use my multimeter to see which solder points are good because at this point they all look the same to me! Haha, I can't wait until this works... thank you for your help by the way.

 

[rasgal]

dont use the multimeter. sends out voltage(7-9v i think) if you use the beeper, witch is not good for the IC's i guess.

make sure you only measure ohms.
it's hard to measure electronics with a multimeter without the diagrams.

i would just have looked, u should easly see solder splash if there is any.

check that you have soldered where the guide tells you to do.

 

[Bullet1979]

Wow, I hate to fall into the category of people who don't look at things thoroughly but I totally missed a solder point on the rebuild.... THIS WHOLE TIME all it was was a solder point that I missed!! I simply overlooked it.

For future reference, the point I missed was on the rebuild next to pin 7. This whole time I've been inspecting my solder points that I've made... when I really needed to just do one more! Thanks Rasgal for your help... now all I have to do is figure out this FlashBIOS.

congrats m8.

help fixing what someone else did

ok so i had someone bring me a 360 ith a 7 series lite-on they tried to dump and flash themselve but screwed up cutting the traces so now its up to me to try and at least dump the key to spoof to another drive if needed i have a vampire probe and maxius pro power dongle heres some pics of the board

Re: help fixing what someone else did

It looks doable, its bad but i wouldnt say its beyond repair, if you have any problems with it let me know as i may be able to help after having to fix the same sort of thing

Re: help fixing what someone else did

there should be alternate soldering points on the other side of the PCB, as it looks as if they ripped out point 101

i'm searching for the link i just saw the other day

 

[adamwat11]

Re: help fixing what someone else did

that should be the best way to repair it if your vampire probe wont work then just use the 7 series probe to exract the key, if the hole next to number 3 is to damaged let me know and i'll tell you where to bridge that trace to

Re: help fixing what someone else did

Or just probe it...its a 7 series.
