yup, did the same thing here - i broke the soldered bottom part of the connector off the logic board. i think the key to getting it off correctly is to use the spudger from the back to loosen the connector, where the wires are. if you use the spudger from the front, as i did, then it's easier to break the whole connector off -- or that's my guess at least.

looking now to see if i can solder it back by myself.. ;Z

another great tutorial ~ this was very easy, took maybe 10 minutes max, and now i have a noticeably faster computer. i agree with the previous comment that you need to push the new ram in rather firmly.

it's really easy to do this - there's no need to pay someone else! thanks for this awesome tutorial.
