Something is seriously wrong

Hello Internet,

I'll go straight to the problem
I think I bricked my phone

It all started when I was trying to view those damn emoticons that iPhone users keep posting on twitter
a few google searches said that installing fonts to view these emoticons requires rooting
so I rooted my device using Odin
It worked fine
but then I tried installing the fonts
there were 4 of them
the first one installed ok
when I installed the second font
my phone rebooted and nothing appeared on the screen
it only shows the "Samsung Galaxy I9300" part and then nothing
I rooted it again thinking that it might help, and it didn't

now I am trying to unroot it or do anything to make it work
My country "Bahrain" isn't on the firmware download list on sammobile
so I chose Saudi Arabia which is right across the border and their carriers don't lock their phones
I am writing this while the firmware is downloading
but it is taking FOREVER
the old firmware ended in DLD as in XXDLD .. there are more letters obviously but I can't remember
There is another functional unrooted phone in my house from the same store I bought mine

ANY help I get would be welcomed

P.S. If this is in the wrong section, please move it
