I followed the instructions, but right off the bat it didn't work like in the vid. After download the small cssu app then installing it, then running the app from app manager, it did its long thing, but never rebooted at the end. After that nothing was different, even after I rebooted.

Then a little later I got a notification there was an update for cssu and a bunch of stuff below it which all started with libqtm. Tried updating cssu but it would always say I have to use nokia suite. HOW? I tried connecting it and running the suite, nothing ever happens. I tried running the update on phone while plugged in, but it just says the same thing and on nokia suite it doesn't even say I have any apps installed even though I have dozens. And in the details for all those updates it showed some conflict with libqtm something.

So I decided to unistall cssu. Well that really messed me up. It said it uninstalled cssu, so I rebooted and started all over. Same prob eventually, but now I can't uninstall cssu.
