I'm really far from "rooting Android devices" . I had root my device . SuperSU and CWM installed.
But today i did a mistake and decided to try Facebook Home. So install it from an .apk and then edit build.prop file, changed ro.product.model from GT-I9100 to GT-I9300 . (Also i did a backup BEFORE doing this) . Now i'm trying to boot my phone but it's not booting. Just there is Galaxy S2 booting screen. It's like this :
I have searched it and found a few solutions, but i couldn't follow them because i didn't understand them exactly. For example , in one of this solutions they said "install cm9 mod" but in this page : http://wiki.cyanogenmod.org/w/I9100_Info there is'a warning about superbrick it's scared my.
I have tried booting with CWM (power button + sound up button + home button) and factory reset but i'm getting **Error mounting /sdcard/.android_secure error.I'm trying to mount it from mounts and storage but it's giving error Error mounting /sdcard.
I have really no idea what should i do, i have read a few articles about this but i couldn't understand ANYTHING .
And i really need this phone this evening, i'm going to a travel.

NOTE : I'M USING MACBOOK
adb shell, you can do so and replace your edited
build.propfile with the backup copy you've created (using the
cpcommand), thus restoring the state of before your edit.
adbwill not be able to detect the device, as no ADB daemon is running there.
build.probwith a "b" in the end. I hope you didn't name it such? "prop" stands for "properties", not "probabilities" :) If you put it right, maybe that app you've installed is blocking something. You could try removing it with
adb shell pm uninstall <package_name>.
chmod 644 /system/build.prop
