This is the first I’ve read this, how much of a pain is it to use Linux instead? I don’t have any Windows computers.
You only need a browser that supports WebUSB.
Chrome and Brave support WebUSB on Linux.
How is this possible if the previous step skipped SIM and Wifi setup? I assume, if there’s updates, to setup Wifi then proceed?
I believe that vendors can include updates on the device that sit in the same fastboot space as you’ll be using to install Graphene. By running the system update, it applies any lingering patches, clearing the space for the Graphene install. The update (without SIM or Wifi) will only work if this is the case. So this step is more ‘ensure that there are no updates on the disk that will screw up the install’ than ‘make sure your phone is up to date’… since Graphene has its own methods for applying patches.
