alt Hacker NewsYou can flash GrapheneOS on a Pixel from another pixel, no pc required at all. I've done it several times, this is what sold me on the utility of WebUSB. You can use GOS' own distribution of chromium, Vanadium, if you have a GOS device and you want to avoid Chrome.
Is there something specific in that process that required WebUSB vs just normal USB? Sounds like phone makers could have done this since forever if they wanted to, what makes WebUSB particularly useful for this?
