Blocking Android Firmware Update

Solved Locked

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.

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.

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

Matt Change the 1 to a 0 in Raymond's answer

Hi Raymond.

In Soti manual, for DeviceFeature, it only shows the MinimumWifiSecurityLevel parameter.

Where have you found  BlockOsUpgrade ? Is there a list we may consult ?

By the way, BlockOsUpgrade worked fine for 30 days to me.

Hi Joao,

I asked the same questions as yours many years ago.  Even today, there is no official list in any online documentation from Soti.  Under normal circumstances, users can configure all policies via the web-console.  The likely possible exceptions are the newest or experimental/beta or very device-specific bug-fixing policies, which might be disclosed by Soti on a need basis to specific customers  while the policies still have not be implemented yet in the web-console GUI.

Thanks, JN
