MacBook Pro 13" Unibody Early 2011 Optical Drive
When reassembling, the digitizer and display cable connections very easily come loose. Make sure you press them in securely then I held down the logic board with my left hand while rescrewing it down one handed with my right hand otherwise they would disengage. Took several tries to get it right.
Followed this guide to change the battery. Had to desolder old one and resolder new one. Extremely difficult. Must have bent the screen too much during opening because it would not register touch after, so had to order new screen and follow this guide again to install. Also several frozen or stripped screws to deal with. Cable connections to logic board come loose very easily when putting back together. Took several tries reassembling. Had to hold logic board down while replacing screws to keep connections. Almost gave up but finally got everything back together and working.
Reattaching the battery connector was one of the more difficult parts of this repair. Once you place the battery on the rear cover and the adhesive sticks you cannot make any adjustments to position (even though I tried to just place it as lightly as possible at first). I did a dry run attaching the connector and placing the battery before removing the adhesive cover but I did not get it to sit the quite the same after removing the cover. I had to fiddle with the battery connector quite a bit to get it in place.
Opening my iPhone 6 was so easy using the iSchlack. Well worth it.
iFixit is a lifesaver again. I consider the physical swapping of the hard drive to have been very easy actually. The only thing I had to do different was to use Carbon Copy Cloner instead of SuperDuper! to clone my old hard drive. I had been getting warnings about my hard drive from Tech Tool Pro so I decided to replace it before it failed altogether. I tried twice to clone the drive with SuperDuper! only to have the process fail in the end after running 6 hours. Because my hard drive had some bad sectors and one bad file, SuperDuper would not complete the cloning. Carbon Copy Cloner however easily identified the bad file, showed where it was located, allowed me to delete it and completed making a bootable hard drive. The deleted file could be restored later from a Time Machine backup.
Be sure the three plastic tabs on the bottom of the black front cover are inserted fully when you snap the cover back into place or else you will get a message saying the ink door is not closed.
