I didn't heat the glass using a dryer or glue gun because I have seen a person doing a video on YouTube recommending not to heat the glue as it dries fast and it actually makes the glue harder to remove. Half way through the repair, touch was still working. Every thing was. So I got excited and accidentally nicked the screen. Since it wasn't working anymore (first white screen while I was doing the repair, then went half white/black, then when I turned it off/on again everything was black -- I could still receive calls) I decide to remove it altogether. Didn't know there was a hard to remove residue under it, but anyway I succeeded removing it.
I tried turning it on with the screen removed (also removed the connector to the motherboard) and I got a boot loop (felt vibrations again and again). Is this normal? I assume it is because no screen was connected. This is the current state of my device:
If you notice in the third pic, I also nicked a small part of the black portion of the back, where the circuits of the screen are placed. Anyway I want to ask if I can still purchase a $130 digitizer+screen replacement and attach it again, and do I need some kind of adhesive similar to the one I removed? Or is my device gone for good?
I'm planning to give this to my father if it can still be fixed.
