I've been having issues trying to grab the OTA for 4.4.2--I didn't even know about it for a few weeks! (Just today, 6/5, I learned of it!) My RAZR Maxx HD is running stock and locked, and was rooted. Just to be certain, I uninstalled SuperSU via the app with no success...
Although I don't plan to use the OTA after looking at posts, it's still nice to have the option available should all else fail.
Thanks in advance all.
System details:
Version: 9.30
Android: 4.1.2
Kernel: 3.0.31
Root: Currently disabled, previously enabled
Please let me know if you need anything else!
