I'll start by saying that I DID use Voodoo OTA RootKeeper, and my phone is 100% stock except for the fact that I rooted it with the exploit published a couple days after the Droid 4 was released. After installing the OTA update to JB, my root seems to have broken. Even after using Voodoo to restore root, it doesn't appear to act rooted. Voodoo SAYS my device is rooted and that it had been granted root permissions, but any new app that tries to get root was denied, without me ever being prompted. The SuperUser app was still installed, and I could see a list of apps that I'd been granted/denied root access to, but a new app wouldn't be listed anywhere. I figured maybe my SuperUser app got messed, so I uninstalled and reinstalled it, which was probably a bad idea. Now, NO app can request root, despite the fact that I still have the "su" binary. I tried running the Droid Razr Blade Utility in the Complete Jelly Bean thread, but here's the output: Code: [*] [*] Razr Blade: Motorola Droid Razr 4.1 Root Exploit (Windows version) [*] by Dan Rosenberg (@djrbliss) [*] [*] Thanks to p3droid for assistance in testing.
