Hi just wanna ask if there's a way to properly install or move apps to /system manually in which the app that being said installed will be considered as system app? It seems that my phone is denying my request to install or move app from internal storage to system. I'm using a archos 55 diamond selfie. I've tried to move a certain app installer to /system/app but it doesn't solve the problem. Thanks allot.
Installing apps on the system partition is not possible without root. Rooting can also not be enough if you are running a device that has a newer android version, where selinux is enabled and enforcing.
You need to make sure you do the following before being able to install apps to system:
- Bootloader unlock (if needed)
- Mount /system as RW
- Copy apk file to /system/app (or priv-app) (depending on the OS version)
- Remount /system as RO or reboot
You might also be able to do it through recovery, but at that point you need to run a custom one, as TWRP, the only difference being that you don't need root at this point.
