well first you follow instructions as they say : on the server ... and then you update it only from studio ....did you read the last part of the update ?

What other part do i need to read, i updated  from the studio, it told me that I would only take a minute yet nothing happend

Update from 9.0.1 via Studio

Please, note that this is a Beta release, so it doesn't show in Studio automatically. If you choose to apply this update please:

Edit file inc/classes/BxDolUpgrader.php

Change: 

protected $_sUrlVersionCheck = '_https://v.una.io/';

To:

protected $_sUrlVersionCheck = '_https://v.una.io/beta/'; 

This will allow for beta release updates to be applied.
