T48G firmware update error
We have 2 T48 Yealink phones with firmware 35.72.188.2.

I want to upgrade to the latest firmware. 35.72.0.30 . when we update with the webbrowser it looks fine. Phone reboot but after 1-2 minutes. Update failed reason unkown.

We have a issue with BLF buttons that wouldn't work.

Can someone help us?
