CSCvd63610 - disabling the administrator role breaks admin logins

[Ayman El-BACHA]

After trying to upgrade the FMC from 6.0.1 to 6.1.0, the task status has shown that the upgrade is stopped at 10% and the login session has terminated.

when trying to login I can't and it gives me the following " Unable to authorize access. If you continue to have difficulty accessing this device, please contact the system administrator".

Is their any workarround.
