I tried since the v0.1 to v0.8 of CM 11 by kashifmin to install driver of VIPER4ANDROID and everytimes this apps said me "driver installed, please reboot" (or something like that). After rebooting my phone the driver was not installed even after some try.
Then i try to change my build.prop to add this line (found this tip in the official page of V4A)
But I couldn't with Root Browser, Total commander etc. Then i found on google that i had to mount /system in RW, here also, with all application possible I could not. I tried with Mount /system (rw / ro) and terminal command ( mount -o rw,remount /system ) and some other.
The only possible way for me is to create a file to flash the driver with the recovery but I don't know how to make it.
Is it a bug of cyanogen mod 11?
Sorry for my bad English
