I'm trying to install xposed framework on my little brothers Kyocera Hydro. I was able to root it and give the installer root permissions but then I get this error. Can anyone tell me what this is about and it I can get around it. Its running android 4.0.4 which meets the requirements so I'm a bit lost at what could be the issue.
SD card: /mnt/sdcard/Android/data/de.robv.android.xposed.installer/files
Couldn't mount /system writeable
Trying to continue anyway...
Fail to create backup of /system/bin/app_process
