Angry [Q]Write Protection?

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....

Write protection is enabled on all HTC devices by default.
To disable it you have to flash wp_mod.ko module by flar2 that defeats it or flash a custom kernel.
As there isn't available wp_mod for this device nor custom kernels you might ask @flar2 to look into it and help you or wait for kernel source code.

I think the Desire 816 is like to new one, I don't think hex-editing the kernel version will work..

Flar released a write protection module in original development, but I haven't tried it yet.

I flashed PA's full 4.4.2 gapps over the stock ROM in recovery and it's all good. Have the Play store and services and everything works. Any changes you make in recovery will stick.

Of course, make a backup before attempting this.
