Can I get my Samsung Galaxy Pocket working again?

view story

http://forums.androidcentral.com – I accidentally deleted the fonts folder in my Samsung Galaxy Pocket, and it started vibrating continuously and showed messages with no characters. So I tried to reboot, but it stuck at the first screen and started vibrating again ( tried leaving it like that for some time hoping it would turn on, but it didn't). I also tried factory resetting, didn't work either. Can any one help me undo this? (HowTos)
