hidden menu needs enabled too
to enable hidden menu when rooted
i used ES File Explorer to edit the following file (mount read write / and /sys (unmount after edit. i thin you only need to mount / read write
/efs/carrier/HiddenMenu from OFF to ON (note the caps)
ES File Explorer has built-in text editor so use that.
when editing the file make sure not to hit enter key. just use backspace to delete OFF then type ON and save. dont hit enter. (you might be able to but dont if you dont have to)
these are codes that i have been using on android 4.3 and up stock roms

did lots of testing and these are codes relevant to flashing.
