I bought the first one off eBay from Sydney and got a refund no questions asked. I bought a second one from the USA which their photos of the part were exactly like the original part, Apple symbol and part number, yet receiving the part it is the same as the first one I bought (JBL meks 121437). I am in the process of another refund.
After hours of trying to diagnose the where the signal transmission drop is coming from I gave up, it seems to be around the lower part of the case for me. When the screen is partially opened and still connected at the top (case to case) it seems to work better but not 100%. Could be just coincidence as reinstalling the old part with the phone in two halves worked fine.
Batch of $@$* parts? Could be, I am open to suggestions.
Update - reinstalled old part and it worked fine. Faulty part and getting refund. Will buy from a different seller with guaranteed genuine OEM part.
After replacing the lightning connector assembly I do not get very good signal strength. Everything else works fine and fixed my charge/earphone jack problems. My signal strength is very intermittent switching between 3G and 4G and seldom make calls. I'm guessing this would relate to the antenna connector which I have disconnected and reconnected several times, checked all the screws to make sure they are tight and in correctly around the case. It seems to be a common problem when replacing this part, any suggestions on how to fix the antenna problem?
a) try another part?
b) reinstall the old part?
c) could it be from opening the case?
d) I have no idea...
By the way the guide was really good! Thank you.
