Hello,
This is my first time modding an xbox (or soldering for that matter). I moved my work station to the back of my house to find a well ventilated area but improvised with the setup and tried soldering while in an uncomfortable position. I realized that was a bad idea after burning the R1 point on the QSB part below. I would order another one but it costs over $20 with shipping for a new QSB and being a broke ass college student, that money might be needed for food when school starts.

At this point, I would like to humbly request that if anyone might have a spare lying around to help me out (I will pay shipping).
Or any alternatives to where I can just solder the JRprogrammer cables straight in its place are also just as appreciated.

I think the rest of the CR4 setup is coming along well for me (soldering part atleast), just this little hitch that I ran intoUntitled.png

Thank You,
Manmeet

Hello again,
Ive been reading more and more on these forums today and am starting to get a good basic idea. Below is my current setup, I am trying to read NAND using jrunner and jrprog v2 using the connector pictured in my hand but it won't let me. I am probably missing something very simple, so i figure why not ask here.

(I soldered some of the CR4 wires in place while I was at it, but reading/dumping NAND is my main concern atm)

What does it do cannot continue
Not to be a d**k but your solder joints are Ugly
Looks like the blue and green are going to the correct place
Remove green and blue put some flux on the board build up the joints with solder they should be shiny
solder the connections back on
Sometimes you have to fiddle with order you hook up the Jr programmer
Disconnect JR from PC
reinstall power supply wire
Hook up JR back to PC
Tap F2 on keyboard you should get flash configure
Do you still have the JR logo present in Jrunner

aah, the problem was I left the psu unplugged at the other end. NAND dump was success, got 2 successful reads. Should I be concerned with cpu key not showing up?
Edit; yeah, blue and green are pretty ugly haha. That area in general is a little ugly, but I am planning to de-solder those after this anyways. And they seem to work for the nand

Cpu key will not show up, that's what the ecc and cr4 are for

I was on 15574 but I created and wrote the ECC with 16747. Could that lead to problems later?
Here is the log

Here is the rest of the setup minus soldering everything on the CR4/RST cable. Thought I should post this up to hear from some of you more experienced guys before going ahead. And also because, instead of the diodes, I used one of the QSB components on the underside of the motherboard(pictured below in #3).
