Hi first time I am having a problem of not able to flash custom rom via recovery CWM, here's the problem, I am using Philz recovery whenever I flash zip, the process of flashing went ok, but when all done flashing I press Reboot System Now, recovery takes me to screen that give me a message Root Access is Missing - Root device, then YES -- Root Device (/system/xbin/su) I click YES..then reboot when to Samsung GS4 splash screen then just black afterward instead of seeing boot animation..and after 1 minute when back to recovery..that's it..I know I already double check that I have root access also using root checker everything is ok, I even flash stock firmware through odin no problem and re-root but still doesn't help..do you think I have a problem in /system/xbin/su folder..please help how to fix this..thank you soo much..
