My Xbox 360 RRoD’ed on me twice.

It also had its disc drive die THE DAY I got Skyrim on release after waiting in line for it.

I spent the next several hours learning how to flash the firmware of a broken RRoD’ed Xbox 360 so that I could replace my drive with its parts.

It was simultaneously the best and worst console I ever owned:

Best because I have a lot of fond memories playing Halo 3 multiplayer, Skyrim, etc. with my friends in my college apartment we all shared.

Worst because it was an unreliable piece of shit.
