Can I do this same technique with the Late 2013 mac book pro?
Updated recently to High Sierra and now my Logic Board is “broken” per apples Genius Bar. Crashing and restarting unpredictably. Wondering if anyone else has had this problem or if they think replacing the logic board is a potential fix. I’m not new to tearing down or building computers so I’d consider it if I found a good part.
It seems most of the GPU problems in mid 2012/early 2013 15” retina macbook pro models are due to U8900 IC “lead free” soldering.
Some people pointed that resoldering this IC fixed the problem.

(In the comments for above video, he mentioned that original chip is also working fine)
Just did this and found the hardest part was getting the new board in without ‘loosing’ some cables. I did loose one - the backlighting cable but the the time I discovered that I was in no mood to take things back apart to retrieve it. Worked fine when done but am having a bit of intermittent behavior which I think may be related to a previously replaced SSD card. New one on the way for Monday install.
Thanks for a great, detailed tutorial. Very tedious - good test of patience.
