Screen does not turn on at all (tried replacing charging port as well)
I had replaced my sister's battery recently as it was starting to lose its charge very quickly. However, in a month or so, she comes back with a broken phone that does not turn on or is recognizable to itunes either.
She told me she had used a portable fan that plugs into the bottom of the phone (a cheap chinese brand I think) which I speculated is what caused the damage to the phone. What do you guys think? Or, it's just coincidence and happened to died right after.
But anyways, so I thought it was the charging port that broke. So I replaced that, and still no luck. Also, tried hard resetting as well. If you guys could give any ideas on this, that'd be incredible!
