need help somethings wrong

hello all

i tried to install cynamogen 12.1 from here for my samsung galaxy s3 mini GT-I8190N and something gone wrong.

i installed rom manager from play store but as it wasnt premium rom manage so i had to get the cynamogen rom off here and drop it in a sd card along with g apps.

Opening up rom manager was ok i installed and flashed cwp recorvery, then did a back up and kept saying error with recovery log file which tuns out to be my internal phone memory was full and i deleted and all was ok.

i did this:
5) Reboot to recovery
6) Choose Wipe data/factory reset
7) After wiping go to Advanced and select Wipe Dalvik
8) After wiping (still in Advanced menu) select format /system
9) After formating choose back (or return) to go back to main menu

now i have problems. At the moment when turn phone on see white Samsung logo and bottom buttons flicker white and to clockwork recovery screen v6.0.2.7 with a green android on his back with a red triangle out his belly.
