Hi, try get battery out and wait some minutes, and restart. If you have cmw and a working backup, try start in recovery when you insert battery and do a restore. (hold down power and home when insert battery). If dont work you might have to get back to factory data and flash new firmware. we'll see
hope i helped

 

He does not looks like he's rooted. If so he probably has no idea what you are talking about.

Dcham95, take out the battery, wait a couple of minutes and then try starting it up again, if it does not work then try to do a factory reset through the recovery mode(use the power button + home button combo to enter recovery like qashqool has said above), you will loose your data with this.
If all else fails, you need to get your OS reinstalled, you can either do that yourself via Odin or have the samsung service centre do it.

 

You maybe right my mistake

 

Try to install your Stock Firmware (2.2.1 or 2.3.6) with Odin. There are many Tutorials on How to Unbrick your phone on Youtube. Just have a look. You'll get the stock firmwares from Sam Mobile. You must first create an account to download the firmware. I'll suggest you to download 2.3.6 firmware.

Hope it helped. Thanks
