Phone [Q] Someone help me Please.

I recently rooted my Samsung Transform (SPH-M920, FroYo 2.2.2) And wanted to modify some things to make it look 'n' feel like Android 4 style.

Once rooted, installed MetaMorph and the theme Minimalistic Blue (something looked like Android 4 theme)
I selected: Apply All.
Then all themes applied. But I did not see any change.
5 mins. later: The phone resetted 2 times, these times, with the audio desynched from the boot animation.
It resetted a third time, this time 3 seconds desynched and when the animation finishes, It just shows a black screen... and does *vibrate*..................*vibravibravibrate* Like if some application had to force close. When i try to go into Recovery Mode, shows a sorta-edited screen, something like...
"*The Metamorph Logo in a blue diskette*
Loading
*a "Downloading bar" in static*
And finally, a blue round-square with the text: DO NOT TURN OFF TARGET !!!

Both ways of booting are freezed; I'm scared i hard-bricked my First Android device.

Someone can help me?

P.D. As if were not so bad luck, my Samsung SPH-M920 driver in my PC causes a blue screen that shows up like : ""INTROMISSION"
