I am a Droid Razr MAXX user. I followed the excellent instructions posted by spc_hicks09 in order to upgrade to Jelly Bean 4.1.2. I was on the 4.0.4 last stock release back from June.
Before flashing I rooted using Matt's utility and also kept a backup of root using Voodoo Rootkeeper. The upgrade was definitely a success except for the fact that root access wasn't quite working, but nothing that Matt's root fixer wasn't able to handle. So I had root and 4.1.2 and life was pretty sweet for a day
Until I realized the android.media.process was sucking up 51% of the battery somehow. Upon reading somewhere that it had to do with a corruption on the ext SD card and such, I tried formatting the SD card but that didn't quite work. So I decided to do a "factory reset" assuming that it will only delete data and 1) the phone's system software will remain intact 2) I will still retain root.
Now after the factory reset, it seems like I no longer have root, but I may try Matt's root fixer again to see if it can do its magic. But, right now my biggest problem is that I can't seem to connect to any WiFi hotspots
. It just keeps looping between "authenticating" and "obtaining IP" address. I even tried connecting to some other open and known WiFi hotspots and it still won't connect.
I tried resetting my home router and fiddling with security settings, but nothing seems to work. I was on WPA-PSK [TKIP] + WPA2-PSK [AES] before and that worked fine after the flash to 4.1.2, but no longer works after factory reset. Also, I tried changing security to just WPA2-PSK and that didn't help at all.
It seems like some other Droid Razr users are having similar issues.
Any tips? advice or words of wisdom? Hopefully there is a solution out there for my woes! Please help, much appreciated!
