My samsung galaxy s2 wont turn on

[alllyyy_]

i was getting some free fonts then when i was changing the fonts in setting i clicked on a one of them and my phone turned off.whenever i try to turn it on it never goes past the 4G part, it just dims and un-dims itself.

Might be a software glitch, take it to the carrier and show it to them, if they can't fix it, you'll have to try a factory reset.

Hold the power and volume down keys until it turns on and a menu appears. Use the volume keys to scroll to the reset option and the power key to select it.
