I rooted my Samsung Galaxy Prevail II with Framaroot-1.9.3.apk, granted SuperSU, then chose Gandalph option.
After rooting, I used Odin 1.85 to install recovery CWM_Prevail2_Ring_Koumajutsu.
It would not boot all the way. It would get to the second Samsung logo and flash it on the screen. I waited for an hr. It never booted.
I tried to install SPH-M840_MH5_Stock, that has bloatware removed. Still fail.
So I was frantic and started formatting data and cache cuz it said "can't mount data (or cache).
Then I saw a mounting option. So I mounted everything it would let me.
That got rid of the "can't mount" errors, but it would show a yeild sign below the first Samsung logo.
And when I try to restart from recovery, it says no root and does the yeild sign. And the whole time I have been working on it, since I flashed the recovery, it says "can't find /tmp/recovery".
So. I think for the no root error, formatting it, removed root...
HELP PLEASE!!!

Blessed be,
Toxic
