Help Htc evo not turning on!

[mynameiskaila]

Whenever I try to turn it on, It will go to the Sprint screen then to the 4g screen, then back to the Sprint screen, then the 4g screen, then back.
It just goes in a circle.

It keeps doing that over and over again! I can't get it to really turn on .

I have no clue why it is doing this or what to do about it. I'm only 15.
My phone has done this before, and to fix it I had to hard reset it. I really don't want to have to do that again.

It's Sunday, so the Sprint Service Centers are closed. And I have school next week, and I would hate to be without a phone.

If you know how to fix this, please help!

Well you might have to do the hard reset. Take the battery out and put it back in.

I dropped my phone on the power button and it will not work now. i switched to a lesser phone and now im trying to pay the $100 sprint requires to replace it, but its been deactivated for too long and now i need to reactivate it in order for it to be covered under insurance problem again.

the power button doesnt work so is there any ways to power it on with out using the power button??
