We covered the other day how to root the Chromecast. You can check that here. Then if you went back to yesterday, or possibly the day before that, Chromecast received an OTA update. Great, fantastic, sign me up? Yeah, not so fast.
As with many updates these days, they are often only to take away peoples fun. In this case, that is patching up the bootloader exploit which was used to get root. That’s really all you will get out of this update so don’t even think about updating at all, unless for some odd reason that’s what you want to do.
We didn’t cover this update manually and I don’t expect to be any time soon either.
