Thanks. I’m reading through this, and you might have to explain it to me like I’m in second grade, even though I’ve installed Linux systems on laptops from a USB boot many times.
If I’m reading this right, it looks like I need to download a bunch of things (or use sudo commands) on my Linux laptop and then link a USB cable between my laptop and phone. The bootloader screen on my phone that appears when the phone boots up (telling me I’m running something other the Google) is the first time I’ve seen anything on that bootloader and I’ve never run commands on a phone before. Do I need to download Android Studio onto my laptop or do those command lines install it?
It will ask you to “allow” the ADB connection when you “add” your device to Chromium, and then it should proceed with flashing just in the browser.
