Firmware upgrade

 I  tried to upgrade the firmware of a yeastar S50. The S50 suggested the new firmware (30.8.0.8).

After clicking it says UPGRADING - DOWNLOADING but does not progress. I started 4 hours ago and still says 0%.

Is this normal?

How can I check the upgrade is being perfomred?

Can I cancel the upgrade to start later?
