Error 16 after changeing the modchip

[Eisbier]

First say hello to the members!

After years i found my xbox again  . I have a 1.0 with a xecuter 1 modchip and i replaced the dvd drive to a Samsungs SD 616. I thought i would be nice to have a modifed box with more than my 80GB HDD. So tried my best. I solderd out the old modchip, replaced it with a cheap aladdin from aliexpress an removed the capacitor for the clock. Now i have the problems. I got an error 16 when i started up the box. No EvoX logo is shown on the screen. No DVD like OGXbox Installer ist working so far. The led on the modchip ist red when turned on.

I tried this with the old cable and old hdd.

 

I think the modchip is not working.

What are the possible problems? Did I some mistakes with soldering? Is the modchip garbage? Should i flash the chip out of the modchip. If this is correct. Witch cheap programmer should i use. 

Thanks for your help!.

Pictures of everything will help 

[Eisbier]

sure, here are the pictures. from the D0 to pin on the backside i have continuity. This is tested. 

Is a map of the board available where continuity of every pin is shown, to check this?

 

Thanks for your help!!!

[Eisbier]

and the chip itself

[dtomcat]

Do you get the error without the mod chip installed?   And the LPC soldering needs some work.  Not sure it’s making good enough connections on some of the pins 

[dtomcat]

I’d recommend getting some flux and try to get the LPC soldering a lot better 

[Eisbier]

i tried to resolder the pins. Here is the result. I get the same error code without the modchip. This is why I am thinking the chip is not working. I got these codes:

Modchip, DVD, HDD installed  Code 16

DVD, HDD without Modchip    Code 16

Modchip, HDD without DVD    Code 11

Modchip, DVD without HDD    Code 07

the HDD is not the original HDD, i used it with executer 1.0. i Tryed to install the original one, but unfortunately this device is broken. FatXplorer cant' recognize it either.

[dtomcat]

Have you tried putting d0 to ground and see if chip boots?

[dtomcat]

And are you sure that the new hdd has stock dashboard correctly moved onto new drive? 

[dtomcat]

Error 16 can be that the Xbox dashboard can’t load to set the clock

Like @dtomcat suggested, do NOT use the D0 on the chip. It doesn't work on Aladdins. You are probably booting the stock bios on the TSOP and not booting from the chip at all. Ground the mobo d0 to a ground pad or a screwhole ground pad. THEN try to boot. Don't wire up the chip at all.

[Eisbier]

First let me say thank you for your help. I will test this this evening.

[Eisbier]

If i ground D0 (Xbox Motherboard backside) to ground, the Box tries to start, fan starts for 1 sec. This repeats 3 times after that the box shuts off, red and green blinks rapidly. There is no output on the screen.

That soldering is a nightmare....

[Eisbier]

@Marty I did my best. I know it is worse. This is why I asked for a map to test continuity.

[dtomcat]

So the FRAGing (flashing red and green) when d0 is grounded means it is either the soldering (probable) or bad chip. Your soldering after second time looks better… but could still be the issue.  I hesitate asking you to keep trying because you could burn up the pads with too much heat.  You really need some flux. I wouldn’t recommend trying without flux.   Is the hard drive locked?   Do you have an EEPROM backup?  

[dtomcat]

What temperature do you have your sooldering iron set to?  What type of solder?

[Eisbier]

@dtomcat Harddrive locked, I don't know. I installed the HDD 2002. I don't have an EEPROM Backup, never thought I need this. 

My soldering stick has 30W with max 380 degrees an I used this Flux

[Eisbier]

maybe I have damaged the borad, possible. Can I check if the pads are working probably? Are the any points on the motherboard where I can check it. The ground Pin works fine. 

[dtomcat]

A you try to get a really clear close up picture of the LPC soldering. We may see something.

In my experience, this liquid flux is REALLY not ideal for LPC soldering. Find yourself a bottle of Amtech flux. It is MUCH better and will behave more in the way that flux traditionally does.

I’ve always been partial to the paste flux over liquid. That’s just a preference of mine. I also usually tell people who are starting out to go with a paste or gel type until they really get the hang of it. When people start out with liquid (having never used anything else) I think they tend to not use enough of it. IMO.

@all thanks so far. for the next days I'm not at home. I will order new Flux an try to do a better job  . I will post an update, when this is done. Merci!

[Eisbier]

Hi! I'm back. Unfortunately the flux hasn't arrived yet. But in the meantime I cleaned the solder joints. In addition, I tried to check whether the soldering points have connections to places on the board. Attached are the pictures (i hope better) of what I found out. Each PIN has corresponding connection on the board. So I think that the soldering points are working and re-soldering wouldn't make any improvement.
