Be very careful of the ZIF connectors. They are very tiny. Go slow and use a magnifying glass if you don't feel comfortable on disassembly or re-assembly.

I completed this repair. Very difficult. Took me about 2 hours. Be very careful of the ZIF connectors and the tabs. Make sure they align perfectly and are gently pushed in, and all the way in.

I had an issue with replacing the digitizer after replacing the battery on the A1474. The digitizer cracked during removal while doing the battery replacement. All went well with the battery replacement, although this is quite a difficult repair to do. When I installed the digitizer after the new replacement arrived from Amazon, I tested it before sealing everything together. All tests passed, no problems. When I got the unit repealed (everything working), I noticed a tiny spec of lint or something on the interior of the glass between the LCD and the digitizer. I had to take the unit apart again to clean the spec off, and when I re-assembled, the digitizer doesn't work now. I have never had this happen before despite doing a lot of screen replacements. I see from others posts, that Kapton tape is required to be placed at the bottom of the digitizer to avoid 'digitizers gone wild' like I am experiencing. Ordering Kapton tape today. Wondering if anyone is experiencing this with the iFixit Digitizers.
