True, I've "bricked" my Android phone a few times by flashing a new OS version, and always recovered it with ADB.

That's a 'soft brick'. It's a strange term, but necessary to differentiate from phones that will never turn on again.

It's difficult to brick a phone these days.

I know, the point of my comment was that it's almost as hard to brick a phone as it is bricking a PC. You've got to kill the bootloader to achieve this, which rarely happens, even when you flash a corrupt OS.
