1 My screen shattered and my phone is now dead. Can it be salvaged?
Hello everyone. A few days ago, my iPhone had an accident that caused the screen and most of the upper portion of the phone (i.e. the front facing camera and earpiece) to shatter. To be more detailed, the cause of the cracking was a result of one of my headphones being wedged up against my phone and pushing against the it until the regions described above cracked. As a result of this, the screen was left mostly black (i.e. no light/color) in the bottom left, right, and upper right portions of the screen. The upper left portion, along with some of the bottom left of the screen had been left with the "rainbow lines," which I discovered through prior research to be a result of a broken digitizer or LCD (this is not the part I am concerned about; the “rainbow lines“ can also be seen through a former ifixit post such this My iPhone 6 has lines and black spots all over the screen). As of yesterday, my phone was fully able to be tracked via Find My iPhone, received notifications (as evident of the vibrating of my phone), and I could feel the haptic feedback as a result of the phone asking me for my password. This leads me to the current predicament I am in. To be brief, yesterday I was taking screenshots using the home + power buttons to see if the on-screen flash that normally appears would somehow show up in the damaged "rainbow line" portion of the screen (it did not). After doing this a few times, the phone suddenly shut off (in that the rainbow lines went away and the phone became untraceable, failed to receive notifications, etc). So my question is if my phone would be fixable? I have a lot of photos and contacts that I would like to back up (something that I have regrettably failed to do since this October past). I know I will need a screen repair and that that is not an issue, but I am more concerned on whether my phone can be fixed to turn back on and allow me to back up my data. I tried charging the phone earlier and felt the top portion of the phone grow warm (which is normal; it also was just faintly warm and not scalding hot), something that I hope is a good sign that it can be salvaged. My current hypothesis is that the phone somehow short circuited as a result of the screen crack but I am honestly not 100% certain. Thank you for any help you can provide!
Это хороший вопрос?

Have you tried to connect this to a computer yet? If the phone is still working you should be able to see it from the computer. You should also be able to back up some of the data this way. But if it pops up there's a decent chance that the phone is still working.
I would encourage you to try to narrow down the problem before assuming there is a short, since it could be a hundred different things. If the device charges that means it's at least partially functional. Just troubleshoot it the good ol' fashion way instead. You'll likely save yourself some money. Consider opening it up, if it is a short and it didn't destroy and components then it's possible it will work fine once the screen is removed.

Yes, I have tried connecting the phone to my computer. Unfortunately, the device is not recognized. I assumed it was charging due to the fact that the top of the device grew somewhat warm while in the assumed charging state and later cold as a result of reaching full capacity (although I may be wrong for assuming this). I'll definitely investigate it further. I just find it very odd how it worked for a few days after the incident to all of a sudden dying altogether. If you have any other suggestions please feel free to send them here. I'm always checking for updates to the post. Cheers!
