Thanks, I plan on doing this when my phone dies. Just some questions:

A computer with a Chromium-based browser (e.g., Google Chrome, Brave, Microsoft Edge, Vivaldi?). Unfortunately, I must recommend Windows 10/11 here, because then you don’t have to mess around with any drivers; it’s the simplest option.

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.

First of all, we need to make sure that our phone’s software is updated to the latest available version. For this purpose, we go to Settings -> System -> System update. If necessary, we update

How is this possible if the previous step skipped SIM and Wifi setup? I assume, if there's updates, to setup Wifi then proceed?

securing the phone with a fingerprint; I personally am an advocate of this solution...

Recommend not doing this for users in the USA, as police can compel you to unlock biometric locks. Yes, it's fucked up, that's what happens when octogenarian fascists run all three branches of your government.
