What mobile phone do you have?

Been having huge problems with my Samsung Galaxy Ace lately, in fact it won't even turn on anymore, if anyone can help please tell me.

Here's what happened:
I was downloading video files... When I decided that I wanted to delete just ONE video, all of them are gone (the downloaded ones only, not other files), so I figured that it might be a corrupt SD card or maybe a virus. I tried to delete everything on the SD card, same thing happened again. So, I decided to try a hard reset. I don't know if I did it wrong or if it's something wrong with the phone. Anyway, I went to Settings>Privacy>Restore to factory, or reset, or w/e I don't remember exactly what it was.

Now after it's done resetting, it kept restarting the phone. Before it's even done starting, it restarts again, and again nonstop until I take out the battery. A friend of mine told me that I need to install a new ROM, tried CWM 5.0 (I think). Now instead of restarting it stays stuck at the first screen where it says, "Samsung Galaxy Ace S5830" forever, until I take out the battery or it runs out of power.

I should've saved the money I spent on that phone for an iPhone 4S, I'm not even too greedy for the iPhone 5.
