Yes, I read the answers to the question by the link Disable mobile data permanently but I'm interested in a solution related with directories and files on rooted-device and not in using an application or setting(s).
I also read the comments to the question Delete mobile data using Root but the deleting
/system/etc/apns-conf.xml dosn't help and I don't have the
/system/app/telephony as well as
/system/SettingsProvider.apk, maybe because I use Android 4.0.4 (?).
I know that to disable Wi-Fi it's enough to obtain root permissions and rename the folder
/wifi inside of the
/etc to another e.g.
/wif. Can we do something like that to permanenlty disable also mobile data for example by renaming some directories or files or edit some file(s)?
