Thanks so much for your guide! I actually completed it. However, even though I changed out the antenna, my wi-fi and bluetooth still don't work. I think it's probably a wi-fi logic board issue. sigh.

One thing I would add to this guide or anyone attempting to complete it would be to wear gloves while handling the LCD and screen plate! I slightly touched the LCD and it was a pain trying to get my fingerprints off of it without smearing.

Also, steps 44-46 were a bit different on my iPad Mini 2 64GB version. Not sure why, but some things were different internally. So I kind of had to wing it and just use my own gut judgment that I was removing and adjusting the parts correctly. But after that I was fine.

Thanks for the guide. Since the logic board is $100 to replace, I just purchased a new iPad and am going to sell my broken one for parts.
