LCD stuck in "Updating Firmware"

Hi, f5 guys,

I updated f5 i5800 before several days from 12.1.2 to 13.1.1.2, and on the LCD I see a message:

Updating Firmware

This can take up to 30 minutes...

Please do not interrupt!

It's like there is an issue with the LCD.

I can access the device through SSH, but can not see anything related in the logs. The display doesn't allow any touch activities...

I tried to check what is the problem here (in DevCentral) and find a proposal to restart service "fpdd" (as I understood this is "Front Panel Display Daemon"), but there is no such service:

[root@F5-BIGIP-Host-1:Active:Standalone] config  tmsh show sys service  | grep fpdd
 [root@F5-BIGIP-Host-1:Active:Standalone] config 

I perused all the services, but didn't find anything known to me...

Any ideas about this behavior?
