IPhone 6 black screen flashing logo?

Okay, so this guy asked my dad to fix his iPhone(why my dad, no clue). Anyway, my dad his been trying to figure it out for a few months, and a few weeks ago the guy stopped responding to my dads messages. So, we figured if we could get it to work we could use it, if not just trade it in. But the issue is this: whenever it isn't plugged into the charger, it won't turn on. And when it is plugged in, you can't get to the home screen. I tried to do the home+power button trick but when I do that the apple logo comes up for a second, and then the screen turns blank. But it's still on at this point. How do I know? Well, when I look at the phone at an angle, I see a dim light emitting from it. What should we do?

Help can my iPhone be hacked?

So I was on the YouTube app listening to music and I don't know how but I clicked on someone's account (the person was Indian if that matters) and as soon as I clicked on it, it directed me to this weird site and usually when I click on channels of people on YouTube It just shows me their page of videos they liked or what they uploaded (you know what I'm talking about)But this one was weird and different, it went straight to safari and a weird site and the person had so many videos about how to "hack" and "jailbreak" does this mean he could hack my I have the iPhone 6 can he see my photos and album And hack my whole phone?

My iphone 4 has water damage and won't let me off the lock screen?

I spilt water on my iphone 4 but just left it on the side for a week. So she I turn it on it freezes on the lock screen and won't let me touch nothing so I tried the thing where you hold the two buttons down and when it goes off I turn it back on but that doesn't work.
