Make sure you watch XJohnnyGunsX
video on installing the DemoN in a Trinity, very educational.
Also, not sure what iron you ended up with, but I would highly recommend something like a Hakko FX888 or a 936 clone (analog not digital) before you undertake installing a DemoN. Also, buy a assortment of tips for it. I have done a bunch of soldering and a few mod installs since the first playstation, and it still took me two days to work up the courage to solder that tiny row of NAND points! :tongue:
Flux is your friend, I used
this and found it to work very well. I know there is another brand the pros here rave about, but it is pricey and apparently hard to come by the genuine product unless you are buying from the right people.
Best of luck and keep us updated on how it turns out!
