Xreal Beam doesn't complete update

Received my beam today.

Beam doesn’t complete update. It stops at about 150MB out of 830.7MB and I need to start over again. So I can’t use it.

Tried many times.

What should I do?

Is there a way to download the update to my PC and manually update the Beam?

Hi, please just leave the device at the status of update, it may stop at 20-30% for several minutes in the first update.
The only way to update is OTA.
