I was s-off already before and somehow it shows s-on now. I've tried rumrumner, revone, and firewater. They all success but it doesn't show s-off on the bootloader. On firewater it shows there really isn't a helluva lot to do here. bye bye. Which I use google and found that it means I have s-off already. Could it be a bootloader problem? I tried fastboot getvar all and it shows s-on.
