Blocking Android Firmware Update

Blocking Android Firmware Update

Hi, 

I have some Samsung Tab Active 2 devices currently on Android 8.1 which will start to receive updates for Android 9.  I don't want them to do this as our app (loaded via package & profile) has not been tested on this version.

The question of how to block an OS update has been asked before via this link and an example was given for set_system_update_policy , which I have applied. 

My question is: didn't there not used to be an option within Feature Control to stop all firmware updates?  And if anyone has any other tips to stop the updates through MobiControl I'm all ears.

Eddie

If I remember correctly for some tests on Samsung devices using recently released AE device agent, the following has recently been added and worked fine:

 

   writesecureprofstring DeviceFeature BlockOsUpgrade 1

   apply featurecontrol

 

Unfortunately, I can't remember the device agent version number or the device model.

I've applied the script and have received no errors to say it's unknown/not allowed. I'll keep you informed.

This script worked great for me on a Samsung Galaxy Tab S4. But how to I enable the OS update once we have approved it? I have tried modifying the script but don't know the correct command set or syntax to disable or remove the feature control set by the script. Changing the "1" to a "0" seems to work but wanted to make sure this was the proper way.

 

Thanks,

 

Matt
