I don't think you need to unlock to install any of them. I think that guy wasn't paying attention and thought you were trying to install a rom. You will probably need the sdkcerts.cab as well though since I had to sign it after an edit. To be honest though, I haven't tried it on a stock ROM.

As for the freezing from the version you have, some versions of HTC Home do not work with 6.1 that well. It was kind of a big issue for people at the time 6.1 ROMs started coming out. I don't think there was ever a fix besides a hard reset and then getting a compatible version of HTC Home.
