I don't think having a FRESH ROM or wiped "anything" really matters all that much. I have and am STILL having the missing LTE issue now. I flashed CM12 (from this thread) onto my volt...tried APN fixes and whatnot. I didn't like it/never fixed the lte issue...figured okay - I'll just do a restore from my recovery (Teamwin) and I will be good to go...I've done this on previous phones...from not liking ROM's and such...so I do that...restore my backed up ZV5 rom from yesterday...I STILL have NO LTE...obviously the restore/backup procedure is NOT clearing out everything as I expected. So fresh roms/wiped data (to me at this point) means nothing. Data is not being cleared out correctly or bad data is being retained and tainting our backups.
Also of note - trying to get myself LTE back - I did the restore my phone to ZV3 method based on what others have said...my phone was actually un-activated from the network - I posted previously on this thread. I restored ZV3 using the LGFlash Tool. I got that back - I have my phone back up and running...but I STILL DO NOT HAVE LTE (4G).
I really like 4g and use it for gaming (when I'm bittorrenting on my home network).
Any ideas?
Thanks!
