Trouble Factory Resetting Device

[RemusW]

I received a Hololens 2 that was previously used by someone else. Their account is currently signed is so I have been trying to factory reset it following this guide provided by Microsoft here . However, when I trying to follow the "Clean-reflash" section it requires me to be signed in to perform the reset. This results in a chicken or the egg problem as I don't have access to the signed in account, but I am unable to reset the device to log into a new one. Are there any other reset options?

Resolved. You need to do the manual installation instead of the normal one as in the documentation.
