Chosen Solution

Hello! So my iPhone 6 had numerous issues (cracked screen, wear out battery, lighting connector made poor contact) so I decided to replace all three of these components. I ordered from iFixit the Front Panel Assembly, a Battery and the Lighting Connector replacement parts. After careful work and by following the guides to the letter, the iPhone won’t turn on, or at least that’s the impression. The screen is black and iTunes doesn’t recognises anything. Before the replacements, the iPhone’s battery charged up to only 7% and later used to restart by itself constantly. Thus, I opened it and removed the battery, leaving it like that until the new parts arrive. Any suggestions/ideas? I double checked the screen’s connectors for contact issues, but all seemed okay. I would appreciate any feedback. UPDATE 1: The phone works with the old screen back on. New screen seems to be defunct. UPDATE 2: The battery and the lighting connector replacements both work properly. UPDATE 3: I contacted iFixit and a new screen is on the way! UPDATE 4: The new screen works properly and the phone is fully functional. Thank you all for your ideas/suggestions!

Assuming you turned it off and disconnected the battery before you started, I would say the backlight circuit is ok. You may have just got a bad part….it happens. Go back to where it was working fine and powered up. Put your old parts back in and test it. Then, start with the battery… Make sure you always disconnect the battery first before making any connections with the lightning connector and LCD. Keep track of the screws…. make sure each and every screw goes back in the same hole it came from…you can also experience the powering up issue if you already put the wrong screw (In the LCD Shield cover) in the wrong hole (Can cause “Long Screw damage”). If your phone comes on with new battery, check it connects to Itunes (You will get a boot loop if the battery is too low or not connected with lightning cable connected). Then check your new display… Disconnect battery and attach your new display to test. Once you have verified your new battery and lcd are working properly, try your new charging port. Post back your results and any more issues you have to get better advice on what may be happening.
