I bay and install "Bluetooth SIM Access Profile" then i install "Bluetooth SIM Access Install" and Bluetooth Phonebook.
When run rsap, sim state show me message "sap system files not installed property. Please read..."
I run rsap instalation app v2.4.2. On screen show two option : "Install/update system files" (this option is enable) and "unistall system files" (this option disable). When i click "Install/update system files", app show error "Installation failed. sync mount -o rw, remount -t ext4 / dev/block/mmcbl0p9 /system failed null". What do I need to make an application that would work?
