The New Desire 816w is quite good a device and I have successfully flashed CWM Recovery & SuperSU. It looks SuperSU is running well and root access have been achieved. I also "successfully" deleted apps shipped with the device and installed google apps by coping files into /system/app and /system/pri-app. But after reboot all apps deleted were reinstated while newly added google apps disappeared. The interesting thing is Superuser.apk is lying in /system/app which I think it's due to flash instalation through recovery. I searched online and found wp_mod.ko might be the problem but I can't find it in /system/lib/modules in my device.
Please help and advise....
