Root HELP! Lost LTE!

As good of a guess as any. Who knows. It's really weird though. I don't think I've ever seen so much variation in development quirks in a device. Some people have zero issues, some can't get rear camera to work, some lose LTE and get it back somehow, some like us just get the shaft. Really strange.

Kind of funny that we all have virgin and all have the same problem, with different outcomes. I'm wondering if anyone on boost or sprint prepaid is having this happen?

I'm one of this who lost lte on sprint even after trying everything. I just received my new volt with sprint with working lte I screen shot some of the configurations it comes with maybe someone of you may notice something and figure a fix for those who lost their lte on their sprint volts I uploaded the screen shots to my drop box here's the link https://www.dropbox.com/sh/c4dxqssgninhunl/AADlsBkE4EGyLUMV7TTtgt-Ka?dl=0

Also wanted to say that the problem doesn't exist in the /carrier partition like I thought it did at one time. When you reactivate, even if you wiped out your /carrier like I did and ended up with lg as your carrier, ##786# and full reset with your msl will repopulate that partition and show your carrier again. Can't be the modem partitions either, reflashing the modem doesn't fix it. It has to be either a bad flash caused a hardware problem or an advanced data menu setting, which I'm leaning more towards the latter after the week or so straight i had of messing with things.

Note: I used DD and zeroed out my carrier partition because why not? My volt is broke already, DO NOT DO THIS THOUGH IF YOUR DEVICE IS WORKING FINE!

Also, I'm speaking of the issue where signal drops out every other minute and lte is completely lost but ehrpd still tries to connect. The kind that a simple APN flash won't fix. If your LTE works on a stock ROM or after the carrier apn zip flash, disregard what I'm saying completely, your issue is different from what I have and am chasing down.

Anyone else have the same issue I do? Please sound off here so I know who to brainstorm and try different ideas with.

wow... after a week reading through everything and trying everything... I just got LTE on my phone. I bought it about a week ago at Best Buy for the Sprint prepaid. LTE didn't work out of the box, I was about to take it back and exchange it, but I just did something that made it work. I'm on the stock zv5, even though my phone was zv4 out of the box. I did not have LTE on zv4 and was hoping the OTA zv5 upgrade would give it to me, it did not. I literally tried everything... updating the PRL, updating the profile, reset my phone to factory defaults and doing it all over again, I even tried flashing a radio file, but nothing worked. Oddly enough, I was going through the ##DATA# menu last night, hit APN Settings and used the menu option of "Reset to default". It removed the usual APN settings I've seen on my phone all the times before and put some weird generic ones in there. This kinda put my phone in limbo... 3g worked when I set the network to CDMA only, but I never got any data connection at all on LTE/CDMA. Tonight I just decided to update the PRL and then the Profile... after doing that, I went into the APN Settings again and everything was back. Turned off wifi and changed my network setting back to LTE/CDMA... LTE light up almost instantly... so weird that doing this, out of all things, made it work... but finally.
