My iphone 4s is on a apple logo ever since they tried jailbreaking, what should I do?

I tried shutting it off but it takes to long. It keeps showing a low battery after the apple has been on for a while so I charged it but it makes no difference.Someone please help me on this.

Sounds like you made a bad choice letting someone try to jailbreak your iPhone. Time to not jailbreak your next iPhone. Sorry dude.

You will have to put it into recovery mode and then you will have to re-install the whole iOS again, by that you will lose all your data in the phone. I hope that you already have a backup file in your iTunes so you can restore everything.
