My iphone 5s screen had shaking black, grey, and red lines?

In august of last year, I got water in my screen and the screen started randomly shaking and switching screens, as well as typing completely random things. It stopped doing that about two months later, but then a teacher threw it on her desk and it started acting up again. It hasn't done that in around three months, but then today I was riding my bike and had my phone in my waist band for about thirty minutes. Everything was fine up until I was almost home; my screen turned a light grey with multicolored shaking lines (the home screen, and just about everything else appeared to have a double). I got home and tried to back it up to iCloud, but it wouldn't let me open the setting to turn it on. The screen then turned a blackish grey, with red, black, and grey lines that seem to fade in and out. I've tried the "magic" restart method, but to no avail. I've also tried plugging it in to charge, but that hasn't worked. I heard that you can try to clean where the battery is to get out all the water and gunk, but I can't find the "pentalobe" screwdriver or a repair kit in any stores. Is there any way that I can fix my phone? I took a lot of pictures from a field trip I went on for my ecology club and my teacher wanted me to send them to him. I'm literally desperate!

How can the FBI not crack one iphone s encryption?

NOT A MORAL QUESTION a technical question. I consider myself above average in technology, but I don't get why the FBI needs help on this. I understand the phone erases everything after x amount of attempts, but surely taking out the storage and attacking it from a separate OS bypasses that feature? Similar to when you forget your password on a device, then boot it from an external drive and change/recover it that way.

How to unlock a iPhone 4 or 4s?

I recently broke my AT&T phone and the only phone I have to replace it at the moment is a old iPhone 4 or 4s (i'm not exactly sure which one it is)

Every time I google how to unlock the phone they want a IMEI number which I don't have. I only have a MEID code which doesn't work the same as a IMEI code.

So I guess what I'm asking is does anyone know how I can unlock the phone or maybe a website that can do it for me.
