in my defense i misunderstood how titanium backup's freeze feature works. thought that made a backup, not that a backup was a seperate operation. saw some thing that made me think i can work around paying for tether by putting the stock hotspot in user mode and clearing the application default, then freezing, so i'm not doing this just to be dumb or anything.
was able to find the hotspotlauncher.odex and hotspotlauncher.apk from a stock rom, trying to run from device (after enable install from non-market sources) immediately gets error "application not installed"
any advice on how to reinstall stock mobile hotspot app on droid 4 much appreciated.
