So, I rooted yesterday, all was good. Used the CF-auto root. After that I got titanium backup and clockwork mod. After that I download the app ROM Toolbox, scrolled over to fonts, clicked a font, pushed continue, device rebooted and it wouldn't fully turn on. It would load up all the way to the Samsung logo and flash blue with that long and have the blue led on. Got scared since it was my first time rooting and stuff and went on forums. Got to clockworkmod and had no progression. Someone told me that I need to download a rom onto my external sd card and plug it back in my device then click that. File didn't work and it said my sdcard can't mount. So I read that I can flash the stock rom from Odin onto my device through the download mode on android. I tried and still am as we speak but it just stays on "system.img". I don't know what to do, and is scared that I can no longer use my device. Is there anything I can do or am I ruined?
Thank you all!
