I rooted my friends S4 mini, put Cyanogenmod on it and he said his phone got ******. He couldn't sign into Google Play or anything. I tried flashing the stock firmware using Odin but it gets stuck in a bootloop, and trying to go into recovery doesn't work. The button presses do nothing, it just boots normally. I flashed clockworkmod earlier to see if that would work, but it STILL won't go into recovery.
