Hi, i am facing a problem regarding my lovely Droid Maxx. I accidently selected the USA band in radio frequency band menue while data connection was enabled and i was browsing. And after that my mobile lost the network signal and it shows that "No service".There are two selections in this menue i.e USA and CELLULAR.I tried many times to select to CELLULAR and it also shows that the CELLULAR selected successfuly.But there is no signal.However Wifi,Bluetooth and Gps are all ok and in working condition.Mobile is not rooted yet.Please help me to get out of this situation.
Thank you...
I answered what I assume is your post on Motorola's forums about this, but their rules do not permit an answer like this one.
If you cannot solve by changing the parameters in the LTE On/Off app, I would think the best thing is to reflash the firmware using RSD Lite, fastboot, or House of Moto (Google "House of Moto") to see if it will reflash the radio with the proper parameters and start again from scratch. More than likely this will be the equivalent of a factory data reset, so it'd be a good idea to back up personal photos/videos etc. House of Moto has a choice to keep user data, but, honestly, I think you should just overwrite everything.
Also, you should know that you are risking (a very slight risk) bricking the phone, but without a mobile connection, I'd say that right now it's psuedo-bricked for you.
The latest firmware can be downloaded from here:

(the latest is SU6-7.3).
