When upgrading the Grandstream Phones using the Grandstream URL firmware.grandstream.com you may notice the phone does not update before or after a reboot. There is a scheduling setting that if enabled with any time or date will inhibit the update until that time is reached. You will need to remove that scheduler date/time and select nothing, then when choosing to upgrade the firmware it will do it immediately.
