I am recently working on IMX6 SABRE -AI board with Android 7.1.1.I have flashed the Images with the help of MFG Tool.I have a requirement to modify my system application(settinngs app) .I modified the settings applications and compiled successfully to generate the settings.apk with changes using " mm -b" command.



I tried to push the new settings apk file in to /system/app or /system/priv-app using adb .but i am getting " read only file system,no write permission" error.


i have found two ways to push the apk file in to /system/apps or /system/priv-app 


1. root the device

2. sign the apk with OEM key.


NXP is not recommending to root the device.


now  signing apk with OEM key , does NXP provide the OEM key?


is there any better solutions?
