problem with resetting MacBook Pro to factory settings

hi everyone,

I'm in the process of resetting my 2017 MacBook Pro to its factory settings.

After I erased my data, I was going to reinstall macOS Big Sur, however, this appears:


Downloading the installer build manifest failed.

also sometimes this appears on my another retry

Failed to download required installer asset. (UpdateBrain.zip).


Is there a way to get around this so I can reinstall macOS Big Sur and finish resetting it to its factory settings?

Thanks in advance


MacBook Pro 13″, macOS 10.15
