This sounds like you returned to Web Installer … ?? … please clarify.
The previous instructions from @piero are to help you with CLI manual instructions.
When you follow manual instructions and are in difficulties you can send a copy of your command prompt output and we can help. Conversely with eosinstaller there is no known log with which one can see progress.
[1] Edit. Whichever method you choose maybe this applies in your case [Solved] Windows does not see my phone in Fastboot mode. This error “Error on step: device-detection” might actually be " Windows does not recognise my phone in Fastboot mode".
