A couple of weeks ago the data stopped working on my Photon Q running CM 10.2. I was on my way to the airport when I noticed and couldn't do much about it at the time. During my time away I had 3G and 4G everywhere I went but as soon as I got back in town this past weekend I lost it again.
I'm in Chicago and I think Sprint recently turned on that Spark network here so it may have something to do with that. I live just outside the city and everywhere that I got 3G before I still seem to be able to get 3G. Everywhere that I was getting 4G LTE I now get nothing. If I set my network type to 3G it will connect, but not on LTE or Global.
I flashed back to stock and updated my PRL and Profile. On 4.0.4 I connect quickly and have no issues with LTE data from here in my home. With CM 10.2 (~1 month old), CM 11 (latest nightly), and Carbon (latest nightly) I get nothing.
Anyone have any ideas on how I can this resolved on custom ROMs?
You're no the only one....
My phone is activated on Prepayd Wireless and eHRPD is dead, same with EVDO data. LTE and 1xRTT is working fine; that leads me to believe its a radio/PRL issue. Unfortunately I cannot get QPST to work at all so I may be stuck.

I am running CM7 RC 1.61 with the 0.01.76.0703_2 LTE radio listed from the radio thread. We had LTE rolled out to our city a couple weeks ago and everything had been working great until last Thursday when I just stopped getting 4G.
I did a full wipe of the phone, flash to the newest version of the LTE radio, went to Verizon yesterday and spent 2 hours there to have them switch out my sim, call their tech support which was no help and still nothing. If I switch over to LTE/CDMA mode on my phone it usually switches back and forth between 1x and 3G never switching to 4G. I have a few test phones from Verizon a Samsung Charge and a LG Revolution sitting at my desk and both have full 4G reception all day without any issues.
Anybody have an ideas I can try or something I can check? I am honestly thinking I need to get a replacement phone....?
I don't run CM, but I believe I saw tosomething on its xda download page listing a way to get 4g to work on CM.

Have you looked at this page yet?
http://forum.xda-developers.com/showthread.php?t=1057757
Yes I looked at that page and tried all of the suggestions. Nothing has seemed to fix it. Also the suggestions from that page have a radio version that does not seem to work with my phone.
But I think that page was for much earlier versions of the CM7 RC for the Thunderbolt.
Anybody else have some ideas????
I have a verizon gs3 that is rooted, running beanstalk 4.4.251-20140301-d2lte. I can't get LTE to work correctly. I can get LTE to turn on if I change my 'preferred network type' to LTE/GSM/WCDMA, but then I have no verizon signal (voice signal). When I have it on 'global', I can get 3G and verizon signal, but never any LTE.
This has been going on for quite some time. I've switched between all of the 'preferred network types' but its always 4G and no cell signal, or 3G with cell signal. I used to be on CM 11 nightlies, thought that might be the issue. I switched to Beanstalk, but have the same issue. Just yesterday, I updated my firmware from here: http://forum.xda-developers.com/showthread.php?t=1788313
Is there something obvious that I'm missing?

I have the EXACT same issue, so you're not alone! Unfortunately, I have no answer for this either.
I was running CM11 (just the stable releases), started noticing lack of LTE a few weeks ago, decided to give SlimKat a try. The ROM is damn near flawless besides this LTE issue. I could actually never get it go into LTE mode through the normal settings, it would always fall back to 3G (and I'm in the middle of a capital city where there's plenty of 4G coverage). However, if I did that *#*#4636#*#* trick to go into testing mode, I could force it into "LTE Only", at which point the phone would be in LTE mode, and enjoy the blazing fast data speeds I pay for .... but can no longer make phone calls.
Anyone else out there experienced this or something similar? Any suggestions would be greatly appreciated.
Thanks!
After doing some research on it, I decided to flash back to stock and unroot. After that, I still could not get 4G, so I took it into the verizon store. I told him the problem, and that I had heard that it needed a new sim card. After doing some simple test, he burned a sim card for me and that did it! I'm thinking that soon after I flashed a CM11 nightly (a month ago at least) I dialed *228 to update my cell coverage. I think that might have fried it. I have limited knowledge on this topic, but I did read somewhere that dialing *228 on some custom roms is not good.
It would be nice if you could take it in to the store without flashing back to stock, but I'm not sure if they would go for that or not.

Ah!! I dialed *228 too! Ok, that's gotta be it. Thanks!
About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
Using Ting (MVNO using Sprint network CDMA) ever since I upgraded from CM11 to CM12 I get intermittent loss of cell signal at times. Every couple of minutes, regardless of where I am or how strong my signal is I will lose all cellular signal for about 20 seconds, including voice and data, and then it will pop back up just like it was before.
I've tried downgrading to two different radios and nothing seems to make any difference. Like I said before this problem didn't occur until I did a clean flash of CM12.. everything was fine with CM11.
I've even wiped/reinstalled CM12 with the same issues.
Does anyone have a solution for this yet?
I recommend keeping your radios updated to LRX22C. Where did you get your ROM from?

From what I've gathered, it seems that sprint networks being unreliable on cm12 has been an existing problem that may get fixed in the future.

Well I fixed it.. sort of. I had tried this before but I didn't reboot the phone.
SETTINGS / MOBILE NETWORK SETTINGS/ PREFERRED NETWORK TYPE
I switched it from LTE to 3G. Looks like I might not be getting LTE coverage but it's hard to tell as LTE is sketchy at best at home and at work... and in either case I'm on Wi-fi anyway. Not a huge deal.
I had tried this before but I didn't reboot the phone after making the change. As long as I leave it on 3G my cell signal never drops. If I switch it to LTE or GLOBAL then it will randomly drop as described above.
I'll retest things after each CM12 update I install see if we get one that works!

Were you able to find a solution for this that you could share?
Honestly no..I just keep it on 3G and there are no issues.
I tried about a week ago switching back to LTE but the display never showed LTE and I definitely wasn't getting LTE speeds and the signal drop returned.
TBH LTE coverage is pretty spotty in my area and I don't use a lot of data outside of Wi-Fi anyway so it's pretty much a non issue for me.
When a CM12 snapshot is released I'll probably try again.
I should add that I dirty flash the latest nightly almost every morning. When a snapshot comes out I'll wipe and clean flash things and go from there.
Update... about a month ago I did a full wipe, going back to stock, did the network updates, etc and all was well.
Then I did a fresh install of cm12.1 and every thing worked great.. Lte and all!
A couple days later I dirty flashed a nightly and got an exclamation point and no data (Wi-Fi is fine). I did find the sprint fix flash which allows me to do the network updates again from cm (had to switch to 1X for it to work) but that only yielded a temporary fix.
I did however find a workaround. If I go to my apn settings menu and change a setting on my ting (sprint mvno I use) entry then change it back and save then BINGO! I have Lte again...
That is... Until I get handed off to another tower.. Then I have to do the workaround again.
Hey Everyone,
I have searched multiple threads and google for an answer to fix the Droid Maxx issue on ATT. Whenever I put the phone on global it works fine for about 20mins getting HSPA+ then all the sudden tries to pick up 4GLTE and the phone stops working no data no phones. So I end up having to switch airplane mode on and off to get it to work again for another 20mins. I can only get it to work when I have it on LTE/GSM/UMTS and I only accept GSM networks which then sticks me on EDGE only. I tried putting in APN settings for ATT and still get the same results when its on global or GSM/UMTS both selected. Ive read everywhere that it works fine on ATT and Tmobile GSM HPSA+ Networks which it does until it tries to go onto 4G LTE network. Any advice would be great thanks!
Hmmm So I continued to look for a solution and it seems 4.4 has issues with LTE on GSM carriers. I found a nice little app that lets me turn off LTE and I am able to get HPSA+ again and no issues with calls/messages. I guess until a fix comes out I wont be able to get LTE but no biggy the battery life on the Maxx makes up for it. I could always root it and go down to 4.2 I have found some posts that said it works.
Is it fully updated?
The Dirtydee Z3
I've been using my Maxx on Cricket (AT&T towers) for a while and I'll get LTE when I first boot up the phone but after maybe 5 minutes it'll go to HSPA+ and stay there until I reboot again. Kind of weird but I haven't had any data issues period.
