If you crack your iPhone 4 screen and you fix it will it reset everything?

Please help I don't want it to reset but I wassup my to fix the screen

Absolutely not. Your just replacing the screen. It has nothing to do with the inside at all.

If you really screw it up you can flash your entire nand or logic board. But just make sure you have no static on you

Your iPhone shouldn't reset. Fixing the screen does not interfere with the data and memory of the phone. Just some advice though, don't fix it yourself. Take it in and let the experts do it. They can usually fix it pretty quick.
