I believe you'll have to engage SOTI support and have them perform an "Agent Injection" into your MobiControl DB. 

The MobiControl web-console only supports agent/plug-in upgrade. 

If your server is on-premises and you had created back-up or VM snapshot before you upgraded the agent/plug-in of interest, then one simple way is to fall back to the old server snapshot.  Othewise, you need to consult Soti support team to do the injection task mentioned by Matt.  That involves working directly on tables in your MobiControl database ( removing the uploaded server binary, uploading the old one if it has been removed earlier, and update relevant tables to point to the right agent binary and hash, etc)

Hi Le,

Thank you for posting in SOTI Central.

We can certainly perform an Agent Injection on your database. That will then result in your local version (db) using an agent version of your choice rather than the latest available via our Agent Builder Service (ABS). You would then need to ensure you don't update it manually via the Manage Android Agents & Plugins feature, also note when you update MobiControl then it'll likely have to be performed again to a similar extent (would need to get Technical Support involved).

As a result of the above, I suggest you open a Support Case at support@soti.net / support.eu@soti.net and we'll then proceed from there.

Regards,

Thanks for your quick feedback. A support ticket has already been opened at the same time as this conversation.
This console is hosted/managed by SOTI, so I'm waiting for a feedback.
