I have a Samsung Galaxy Gio gt-s5660m running on 2.3.4 firmware. I rooted it today and decided I didn't like it. It doesn't really do much. Anyways, I can't seem to unroot my phone now. I have no clue where to begin. I looked and some say to flash a stock ROM which I think means to install original firmware. Except I can't find the original firmware. I don't think I have it. So I'm kinda stuck here. I'm a new Android user and have basically 0 experience in this stuff. I rooted my phone via http://androidforums.com/samsung-ga...0-ace-s5830-gio-s5660-pop-i559-fit-s5670.html where I downloaded the Universal GB Root and installed it. I have random stuff done like backing up everything and downloading Odin but I really don't know what to do...If anyone can help, it'd be appreciated.
