I just updated, below is what I find so far.
Internet connection is way better. I was always loosing connection, and that is good now.
Preware works still, and I updated the kernal, but I uninstalled advanced reset options because the update broke some patches, and when I went to reinstall it, it wasn't there. I tried searching and everything, and it doesn't show up anymore. I havn't tried to reinstall any other patches yet to see if I get the same result.
Blutooth Phone Pair:
Finds my HTC EVO 3D, but I can't place calls, text, or anything. It tells me it can't connect, and to try the call on my cellphone. This is a fail. If I restart, I can make one call and I can see on my cellphone that the call was placed, but I can't hear anything on my tablet. When I switch the audio to my cell phone speaker I can here. When I switch back to my tablet, I can't hear a thing. Try again, and fail
I am going to use Doctor on it, and see if that fixes any of this. If you choose to do this, don't expect to install PreWare and have everything up and running correctly, until updates are made to make all the patches run again.
Ill post an update in an hour or so.
(Make sure you backup) --- (Launcher/Settings/Backup) It will restore most of the apps back after you restore with Doctor.
