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.
