Reflow the solder on the rebuild board using a more powerful iron. The problem is 99 percent the soldering in of the rebuild and LPC points

Well then, it looks like you have a bad chip, or a bad OHM meter. Take your pick. Personally I never use the LPC rebuild boards, instead I use wire to make my connections. Good luck.

It won't be the chip, very very unlikely.
If you check through other posts and indeed take into account I have fully used a batch of 500 of these without 1 single faulty chip over the years, you will see that the problem is always down to issues with high resistance connections on the LPC and rebuild board.
Can you post pictures of the work?

one of the traces came off of the mother board next to the lpc rebuild so my dad had to put a wire to fix the trace that the white wire on the bottom left

Sorry but the problems are clearly the soldering and the install work.
 The solder is not flowed correctly and the joints are really bad.
You also appear to have done some sort of trace repair and the repair wire has exposed metal that is laying across other connections.
 You really need the whole of this re-doing with a more powerful soldering iron and better technique.
Practice on some stuff first

sorry bud, but that's horrible work.

 

do you have a dead mobo to practice on?

what wattage iron are you using?

if it's variable, what temperature is it set on?

 

reflow the solder on your existing joins, clean up the wires (particularly the one thats going through the hole to the other side (a screw goes there!). re-route, re-solder, and i'd recommend getting all the pins on the pinheader. the pins that don't connect to anything might be good practice.

 

those 1.6 rebuild boards take a little practice to get right.

i recommend tinning both side of the connections, then flow them together with the iron.

this is most certainly your problem.

 

btw, chancer's right about chips almost never being bad.

i've gone through about 50 duox2's, and only encountered one bad one that wasn't my fault.

my solder iron is 20 watts i cleaned up everything n reflowed the solder n it does the same thing do u guys think if i got a xecuter 2.6 lite n the xapt1.6/1.6b it would be and easier installation?

I used a 25W regular iron and got Xmas light. Then I  I spend $8 to get a 40W pencil iron and redo everything. It really helps.

why buy some new shit, when you've got a chip and pinheader almost installed.

 

if it was fine before you chipped it, you fucked up somewhere.

you can try a better iron, or keep reflowing with the same weak ass iron.

you could also wick out the solder, clean up with alcohol, and scour with a magnifying glass.

you may have done damage to a trace, or lifted a pad.

 

the 1.6 LPC rebuild is most likely where you fucked up.

tin all contacts (board side, and re-build board side), then line it up and press down the points with your iron until you feel it sink into place. do that tricky one in the corner part first. if the board doesn't move around after it sinks in, you've probably got a good connection.

sodlerless adapters are prone to failure.

always use solder with your chip.

 

duoX2 is the easiest chip to install (in my opinion).
