Broken screen on LG G2 - how to get it repaired?

[Broken Phone]

I broke my LG G2 this morning. I had lost my cover and was going to get a new one but this happened. It is out of warranty and I ordered it on Amazon.de in 2013. The touchscreen won't work.

1. How do I find the serial number without the box and without using the phone? I don't know where the serial number is (I threw away the box and it's not on the back).
2. How do I back up what is on it without giving permission in the phone? I don't want to lose what's on the phone but I don't want to give the phone while private stuff is on it.

I'm trying to connect using LG PC Suite but it won't conne1ct, says "mobile device not found". I heard the connecting sound on my computer when I plugged it in. I think I need to give permission in the phone but I can't do that since the touchscreen isn't working now.

Welcome to Android Central! You can't find the serial number if you don't have the box.

You could try gaining access to the phone unlocking it this way: http://forums.androidcentral.com/ge...de-accessing-locked-phone-cracked-screen.html
