I picked up a second Xoom used off EBay that had the 4G LTE upgrade a couple weeks ago. I went ahead and unlocked, rooted, and flashed the latest JB nightly on it but had not called VZW about activating it for data until today. All along I was seeing a couple bars on the radio indicator with the "verizon wireless" name show up in the status bar. Today I decided to call VZW and add the tablet to my account for data. It has been about two hours, and I am still not connecting over the VZW data link. How do I tell if the radio is working or if the activation is not done correctly or if I need to flash the radios?
In the tablet information it shows the baseband version to be CDMA_N_03.1A.65P LTEDC_U_07.1F.00
I am on build number EOS JRO03L Nightly 126
Odd thing is, when I switch wifi on I get the bars showing on the wireless radio and the verizon wireless name in the status bar, with wifi off I get no bars and "no internet connection".
Signal is weak here, so would that keep the VZW activation from happening? My other xoom gets data signal and works fine, but it is 3G only.
Thanks

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 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!
I've been happily using an HTC MT4G Slide/Doubleshot I got on Ebay since December (I'm in Canada, using it with Wind Mobile, AWG 3G bands). Last Sunday my phone suddenly started showing "No Signal" for the cellular connection (wifi still works just fine), even though I had full signal bars, and I was unable to complete calls, even the *611 carrier service calls. With the Wifi turned off, I noticed I was still receiving emails, oddly enough, even though I could not register on my network. My SIM was working fine in other phones, and a SIM from another carrier (GSM 2G only) worked just fine. I tried a new SIM from my carrier, no luck, same thing.
I know AWS splits its up/downlinks between the 2 sets of bands it uses (1700MHz for up, 2100MHz for down), so I'm guessing something strange happened to selectively knock out the up bands only. But what? My phone is on EmmanuelU's KitKatDS 1.3, but the only unusual thing I could think of software wise was that I had recently updated Xposed framework to the latest version. I though maybe that did something weird to the baseband firmware, so I restored the original stock Gingerbread ROM via ClockworkMod - no change. I applied the available OTA updates from T-Mo - nothing. Re-flashed KitKatDS & restored by current set-up - nothing.
I'm completely stumped and seriously starting to worry it's some freak hardware thing. Anyone here ever experience something like this?
Thanks for any of your thoughts!
Never seen this myself before, check your apns would be my next step. Maybe try *#*#4636#*#* from the dialer and see if what it says there too. But mostly I'm stumped

I updated my N5 to 4.4.3 through this: http://forum.xda-developers.com/google-nexus-5/development/flashable-stock-4-4-3-supersu-t2771010
could not wait for Google to update my N5.
My wife's N5 was updated through official ota.
We are both on TMobile. Same plan. Same zip code.
At home we use to have both LTE signal at 3 bars out of 4.
After the update I noticed this issue where both phones are connected to LTE but now we have 0 or 1 bar out of 4.
often I see No Network at all.
Changing to 3g or 2g will set the phone back on Edge or HSPA.
I think the new baseband messed it up.
Anyone else experiencing this issue on TMO with N5?
Any ideas?
Thanks
I noticed 0-2 bars of LTE at home but mine has always been like that.
i feel like i have less LTE bars than i did prior to the update. In some areas where I have always had LTE coverage, I have HSPA instead. At work I have less bars - I work very close to home (NYC, Manhattan) so i'm not sure if it a problem as a result of the update or service issues in the city - at least in my case.
Bars and signal strength are not necessarily related. The bar is just telling you what the software is interpreting, there have been tons of signal bar hacks that make it more or less accurate.
What I will say is that the LTE drops are something I've seen before even when I paradoxically had "full bars" on LTE only to suddenly have my phone not actually displaying a connection and then it would, after a moment, drop to H+.

Not to sound like a D1ck,But.(I feel your pain)...Finally someone else besides me having issues and I'm on sprint (insert jokes now)the same thing has happened to me my wife my dad my brother and his wife.All of our data handoffs from 3G/LTE hang.I/we have gotten worse LTE.You are not the only 1.I even adb fastbooted back to 4.4.2 to see if the difference is just in my head.It's not.4.4.2 gave me LTE back again.
I am thinking to flash back the previous baseband. Anyone reversed back to the old radio but staying with 4.4.3? I can tell you that the battery life is better with 4.4.3.

Are you seeing that the behavior of handoffs is different or are you losing your data connection more often than before?
I am also seeing emergency calls only in some places like my job, where previously I had 3 bar lte. But at home it stays with 0 to 1bar very unstable. I am convinced is the new base band. Tmo told me to do a switch from 3G back to lte in network settings. After that didn't work they told me to do a full reset to factory settings. Thinking to flash back to . 23 radio.

Both. The hand off is so bad I can't even verbally describe it.My singal drop is so bad I want to smash my phone.(but I want cause I love my nexus devices as much as my kids)
Hello guys! I am christian Abaidoo from Ghana. I use a motorola atrix hd (at&t, jelly bean). Few months ago, my phone was working perfectly until one day I mistakenly selected USA band and lost my network. I then flashed it with cyanogenmod 10.1.3. it was working perfectly but I was only able to access 2g network. Whiles using the cyanogenMod, i searched and searched on the internet for the stock rom for my phone until i found it. I then flashed my phone back to stock rom. Everything is perfect except the fact that i still can only get 2g network. Instead of showing the 4g signal on the status bar as a Motorola Atrix HD phone should so, the 'E' signal rather shows. I cant access phone information using *#*#4636#*#* so I use LTE Settings.apk When I set my phone to 3g, my network cuts off completely and says 'No service'. I thought when i flashed back to stock, i should have everything intact but its not so. I still cant get 3g, I can only get 2g. Guys please i need your help,. 2g is very frustrating. Any ideas on where the problem may be coming from and how i can solve it?. Thanks very much
