#GrapheneOS installation on a Pixel phone is the easiest Android ROM I've flashed in the past 8 years. I used the WebUSB-based installation method. (Also discovered that my desktop has a USB-C port in the back, lol).
I am not a fan of web browsers turning into operating systems, but this is a good use case for WebUSB. I wonder if we can flash Debian-based operating systems images using this, directly from the official website. Removes the need for desktop apps like Balena Etcher.
