disabling mobile Network edition

Hi,

I install the trial suite to migrate a 6.0.14 to 8.0.6
It's work well
I click enable on mobile module inadvertently. try to disable it 2 days later, but when it's disable, mobile account does not work anymore
So i re-enable it, and it's work until the end of trial licence.
I enabled Chat too, people like it

I must uninstall zextra suite and re-install the Zimbra core to get the mobile device working

Now, when i re-install the core for the Chat, the mobile sync is not working, how i am sure that mobile module is disabled ? because i cannot do it via the admin console, the trial licence is expired, and buttons aren't visible.
