[SOLVED] Infinite update MacOS Big Sur

[conly]

Its not finishing update and it's already been more than 10 hours. Don't know what to do. I will try to get the battery empty and see what happens, but are there any other methods ?
MacBook Pro 13 2019 128 GB

I saw this article -- https://www.fudzilla.com/news/51883-macos-big-su-bricks-older-machines

Here is the quote "MacOS Big Sur update does not play nice with late 2013 or mid 2014 13-inch MacBook Pro models and converts their ancient machines to a fetching black screen. "

Looks like what you have although you have a much newer device.
