Here is an album of all the images of the soldering that I did for the Nand-X and QSBs for my phat xbox.

After soldering all the points I get to the part where I plug the usb into my computer, and then the power into the xbox. I set the coolrunner chip to phat and to program on the chip and plugged in the usb and power to my xbox, then the coolrunner chip turned red hot on (the one with the burn mark around it first picture) and started to smoke. I'm not sure if it was the power to the xbox or the power to the usb was a cause of the problem, but I'm was most likely my soldering, seeing as it was my first time doing it.

Does anyone have any experience with this, I'm guessing I soldered a point wrong, but which one was it, and can I fix it? Or is my xbox totally boned and do I need to get a new one. Please any help would be much appreciated.

I have done this mod once before and i had this problem. I went around asking on a completely different forum and found that there was somehow to much power going to the mod chip. Apparently i had soldered it to the wrong point causing a mass overheat on the new chip. Unfortunately it may need you to buy a new xbox. You may be lucky and can remove it without any serious damage. I would help more but i need a bit more info from you.

Where did you buy the chip from? Might be a company selling dodgy chip
Does the console boot? If it boots then it is definitely a problem with either the chip or your soldering.
What motherboard type is it? I had the jasper motherboard when i messed this up.
How long roughly did it take till it overheated and started to smoke? Timing is always critical to know. Ill show you why later.
What size PSU does you PC have and is it home built or shop bought?
What type of PC did you connect it to? and Is the USB 2.0 or 3.0 compliant? Here is how you tell:
A 2.0 has a black rectangle on the inside and a 3.0 has a blue rectangle on the inside.

Sorry to ask so much i am just asking the questions i was asked so please take your time to answer these and make the answer as accurate as possible.If there is any question you can't answer please say and i will try and help you further.

Hope to hear back soon

This not something a beginner should be starting on, there are some pretty fine points to solder to and great care must be taken, did you program the coolrunner first as you havent mentioned it. You may be lucky and just need a new coolrunner.

here did you buy the chip from? Might be a company selling dodgy chip
xconsoles is where I bought it from, and I was following this guide on youtube: http://www.youtube.com/watch?feature=playe...;v=OkuhC7exeow#!

Does the console boot? If it boots then it is definitely a problem with either the chip or your soldering.
I haven't tried booting the console because the underside next to the xclamps where I soldered is soldered on like 3 different points, so I need to desolder that,

What motherboard type is it? I had the jasper motherboard when i messed this up.
This is a falcon motherboard (flat non sperated long line on top then the six underneath for power.

How long roughly did it take till it overheated and started to smoke? Timing is always critical to know. Ill show you why later.
It took approximately 10-20 seconds before it started smoking after I plugged it into the USB on the top of my computer

What size PSU does you PC have and is it home built or shop bought?
I built my computer and it has a 700W power supply.

What type of PC did you connect it to? and Is the USB 2.0 or 3.0 compliant? Here is how you tell:
A 2.0 has a black rectangle on the inside and a 3.0 has a blue rectangle on the inside.
I connected it to a USB 2.0, I only have 2 usb 3.0's on my computer, but it was one of the extra ones with my case that connects to the motherboards USB 2.0 extention slot or whatever you want to call it on the mobo.

from hangover: did you program the coolrunner first as you havent mentioned it
No, I didn't program the coolrunner, but xconsoles sent it out with the 3.0 already installed on it, I was getting to the part to install and make sure the coolrunner was programmed correctly before I went to get my cpu code and everything, by the time I got to the second screen of the program my chip was smoking.

Sorry for the delayed responses, I didn't think anyone was going to reply. I'll check this every couple of hours.

Also I have seen some ribbon stuff that I can desolder with so I'm going to try desoldering the green wire, and around there because I have some excess solder on there, my friend says it looks like its soldered to two capacitors around the solder point by the xclamp so that may be the problem and also when I soldered the ground (which seemed to the most difficult point for me) there was some extra solder runoff that may have touched the chip but I dont think it got underneath it, the solder dries pretty quick before it runs off like that.

Always use electric tape or hot glue to hold your wires in place to prevent wire movement and any chance of lifting a pad.

I just wanted to add something.... It looks like your using too much flux. Also why are you not using the cables that come with the coolrunner. I never use flux for soldering.

Your coolrunner doesn't come pre programmed with any code. Your nand-x came with the version 3.0 code

I had this problem when i first started, i screwed up the qsb that connects to the HANA chip. Make sure that the VCC qsb (long one) isn't conjoined with another point, if it is your coolrunner will start to smoke. Also fix your STDBY_CLK (green wire) you soldered it to many points which will cause your xbox not to boot.

Edit: Never mind the long chip thing, you don't have a coolrunner qsb you have a SMC hack qsb, did you solder to the HANA point? (find TX CR Install guide and you'll know what i'm talking about).

P.S. One more thing if you didn't leave the coolrunner smoking for awhile it should still work when it is soldered correctly. (Or atleast it did for me, my phat falcon boots great with a 1-2 glitch boot time without a resistor).]

Edit 2: Haha I know what your problem is after reading your next post i realized it. If your using Nand-x or a lpt programmer it has a vcc on it so if you xbox was plugged in, which is should NOT have been when programming, the coolrunner got 3.3 extra volts from the xbox and programmer frying your chip!
