The web installer for GrapheneOS list a minimum of 32GB of free space as a prerequisite. Excuse the dumb question but does that mean that is the size of the download? I will be using my GOS phone to install the OS on a Pixel tablet and I was wondering whether to use WiFi or mobile data for the download and the size matters.
The instructions say to not use incognito browsing but is it okay to use a VPN?
Lastly, the instructions say exactly when to connect the tablet to my phone to begin the installation, but does not explicitly say when it is safe to disconnect it? Is it after flashing? After locking the bootloader? After booting the successful installation? Sorry for my dumb questions, I am trying to get it straight before commencing.
Thank you.
Edit: for clarification, I have a GOS phone but had help with the OS installation. That option is not available to me right now so I am installing the OS on my tablet myself
