Its threads like this and experiences that snak has presented in such a well documented way that should give anybody pause who may be considering pogo pins as the "easy" solution. Pogo pins installations cause hard to diagnose problems, are notoriously prone to slip out of alignment when least expected and you'll spend the exact same amount of hours re-aligning them that that you spent the first time you did the install. Take it from me before you go this route...you DO NOT want to try to align these things for hours on end, powering on and off the xbox, praying each time to be greeted with the cromwell screen rather than the xbox dashboard. I can think of few more tedious or stressful things than an xbox pogo pin install, and none that are less entertaining.
I understand that the newer executer versions have LEDs to indicate when proper alignment is achieved on the d0 point, and that may lead to a decrease in the number of posts asking for assistance when the installs go bad. But if you're considering purchasing a pogo pin setup, I would just ask you to stop and consider all the troubles you read in this and all the other pogo pin threads where people are asking for assistance before you make your purchasing decision.
Soldering is not difficult, I hadn't picked up a soldering iron in over ten years when I finally grew tired of "fixing" my pogo pin install and broke down and bought a executer lite. I practiced on an old modem card for an hour or so and then got busy on the real deal. The back-side d0 point is hellishly simple to get right, and if you're familiar with PC assembly/dis-assembly you can do the entire mod in an hour or so.
JUST TAKE YOUR TIME.
Good luck on whatever mod you do, and if things dont work the first time you put the case back together, take a mandatory five minute break to reflect on the process you just performed, and stop and consider what you may have left undone. Are you sure you re-connected both USB contoller cables..the IDE cable is definitely attached right..ect ect. DO NOT instantly decide to pull the mod off or desolder what you just got done soldering. Chances are theres an easy explanation for why it isnt working, and the best solution is always the one thats arrived at by a reasoned examination, not a rushed tearing apart of a newly installed mod. CHECK YOUR SOLDER JOB MOST OF ALL.
Well, Ive typed more than most people want to read so Im going to end my reply. Best of luck, modders....and remember, there's few things more rewarding in xbox modding than the sight of your first cromwell screen after a virgin mod chip install. Good luck and happy modding!
