iPhone 6 won't turn on after battery, LC and front panel replacement
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!
Is this a good question?
