No 4G on AOSP ROMs - HTC Rezound

Hey there,
I've recently switched from Viper Rez ROM to one of the vanilla CM9 builds, but can't get 4G working on it. When I switch to LTE mode under the mobile network settings it goes to Roaming and drops connection entirely. I'm able to get 3G fine. I am on the firmware from the official ICS release as far as I know. I've tried disabling and re-enabling Airplane Mode as was suggested in another thread but it didn't do anything for me.
Any other suggestions? I love running CM9 but no 4G is kind of a deal breaker, and I know it's supposed to be working.
Thanks!

With AOSP and AOKP Roms if you even venture into the mobile network settings you will lose 4G. the only way I know how to get it back is to flash back to a sense Rom, ensure the settings are switched to include 4G and then flash back to CM9.

Really? That's a bummer. I like to keep mine on 3G since the 4G radios drain battery faster and I don't really need 4G service most of the time. I'll try what you said and see if it fixes. Thanks! In the meantime, other suggestions are welcome.

well that's not entirely true. yes, for aokp, but cm9 builds don't seem to have as much issue with it.
i'm referring to the previous post that said that you lose 4g if you enter mobile network settings. not the problem you are having of not being able to get on 4g

4G outage in LA?

Hi guys, I recently flashed BAMF1.8 and MR2. It was working pretty well yesterday, but today I have no 4G at all and 3G seems to drop in and out at random. Sometimes, I don't even have 1x. Does anyone else have this problem? Is it a network issue or did I royally screw something up? Thanks!
im having the same problem i was using bamf sense 3.0 RC4 for a few days nd my mobile just stopped working. two days of flashing roms and radios i still got nothing verizon gave me a new sim nd still nothing i havent tried going back to stock, is that what i should do nd try to get a new phone? after trying to activate my phone online i have 1x now but i did have a few minutes of 3g/4g then nothing again HELP PLEASE!!!
I saw this same exact issue on Das BAMF Gingerstripped and it was really freaking annoying. The fastest solution was a reboot, but it was possible to wait it out until data comes back.
Another thing I started to play with before I flashed to CM7 was using Plane mode as a way to re-engage Mobile Networks (3G + 4G) to get data back. It worked sometimes, but other times nothing. So far running about 24 hours on CM7 and have not had this issue yet, where as on Gingerstripped BAMF I was seeing this problem daily.
I also just flashed the newest radio (1.70) and will see how that works. I'm hoping I just don't see this issue again at all, don't care if its due to CM7 or the radio. I just don't want to deal with it anymore.
Going to airplane mode and back didn't do anything. I guess its a problem with my phone then.
After disabling LTE completely, my phone works perfectly on 3G. Does anyone else in LA have 4G issues? I've flashed a bunch of roms and radios to no avail. I just want to know if I should keep tinkering or sleep on it. Thanks!

try going to a verizon store and see if their 4G devices work properly. at least that'll let you know if the network has issues.
ZIP = 90024
I've had no problems with 4g in northwest LA today. I'm Vanilla Bean's latest release on a froyo radio (can't remember which one, but it isn't the one that was leaked today)
I'm in ZIP 90007 and what's been happening is my phone seems to be connecting to 4G, but it doesn't work and just sits there. =\
It was stolen by Mexicans.

[Q] 4G issues on rooted phone.

My 4g is not coming on a "fringe" areas anymore, and when I am in the heart of a 4g market, it cuts in and out. It will show 4g on the notification bar, but will not connect to the internet, or will just show an upload arrow. It will eventually work if left along for a few mins, but then cut out or freeze again.
I've been rooted since July, and this is the first time i've had these kinds of problems.
I'm currently running BAMF Forever 1.0.5. I don't believe it to be a ROM issue, b/c i have since flashed other ROMS just to test, and still have the same connection problems.
I have pulled the Battery and sim, and made sure the battery door was on properly. I have tried every GB radio out there, and have not been able to fix it.
My big question: Is this a hardware problem, or could it be a bad sim, or something else?
Since my phone is rooted, how exactly would i go about discussing my 4G issues with Verizon? Would it just be best to nandroid my ROM, and install a rooted version of stock? Can i call and ask for a new SIM over the phone, or will i have to go into a store?
My phone is still usable, as the 3G works fine, but I would like to try and figure out a way to get 4G operational again.
If you've read this far, Thanks.

did you go from rooted stock rom to the Das Bamf Forever gb rom without flashing a new radio? there are links in the development forum to the new 802 radios that i would recommend. i'm using that with shiftao5p and 4g is running great.
I am having issues with 4g in my area too. It was just turned on in my area a couple days ago, but I live in the heart of the area and get nothing but 3g. In certain areas while I'm driving I've noticed that it will connect to 4g, but not for long and when i have been able to do a speed test it has only been around 5 meg down which doesn't sound right.
I'm using the latest gingeritis 3d and have tried all sorts of different radios. I've pulled the battery and the sim card and no dice.
Does it just take a little time for them to get everything working and then the coverage will be what its supposed to be?

Weird 4G LTE problems

So my HTC EVO 4G LTE has been treating me very nicely.. great battery life and CM10 is smooth as ever.. the kernel I have is great and I get a 2.0 GHz overclock without problems. The weirdest issue has been haunting me lately. On CyanogenMod 10, I am unable to use the 4G LTE service that is located on a tower about 150 feet away from me at this moment. The issue is that while the phone connects to the service and I can call and text, for some reason data never works. I get 4 bars that I could only get from this tower, and looking in the phone information section of *#*#4636#*#*, I see that the tower shows up as LTE. Now it used to be that on Sense, I could turn on airplane mode, wait about a minute, and then connect to 4G LTE.. but now not even airplane mode can get me connected to it. There should be no reason that the phone can't connect to the tower because the signal, when connected, is very very strong. Does anyone know of any potential fixes for this issue? It's been haunting me that I'm located here in Dallas with a 4G LTE phone on Sprint next to a known working 4G LTE tower and people around me with Samsung Galaxy S3s and other 4G LTE phones are connected but I can't. Thanks for your help in advance.
By the way, I did search the forums and surprisingly no one has an issue similar to this in any of the topics that I checked.
Bump.
Bump.
Did you post the issue in decks thread? That's where I would post, if that's the ROM you're on.

Have you updated your radio's? Are you s- on? What hboot if so?
The newest OTA was supposed to help with lte. It had new radios for it.

I installed the new radio from the OTA onto my phone and I thought it'd fix the problems but the problem was only temporarily fixed when I reflashed CM10. 4G LTE worked for a few hours.. but then after I went into a building, the signal dropped to 1 bar, turned on 3g, and call quality became utter crap.
I would post in deck's thread but I'm not sure the issue is specific to CM10.. I used a sense rom and for the first few hours of use it worked great and I would get strong LTE signal.. but after that I seemed to again be able to connect to the tower that's transmitting 4G LTE and in the network settings it would show up as LTE, but no data connection could be established.

May sound simple, but did u do a full wipe between roms? Factory reset? I know after going s-off I had to call sprint so they could send me an update to fix data and calls.

Yes, I did full wipes between roms including factory reset and system wipes. Only my SD cards are left unwiped.
I called sprint support today inquiring about that but the guy just had me go into ##72786# and reset my network connection settings.. didn't help the problem.. Any name to that update that I can ask them for that'll help me get it?

They should have recognized it if it was an error. So calling sprint won't do much. There's an app called network in google play store. Has the option to switch to different bands, or a lot more than any stock program will let u switch to.
Try switching from CDMA auto to Evdo/LTE or the other LTE options and roaming bands they have on there and see if it helps. Hopefully someone with a fix will see this thread soon enough. Only other thing I can think of is the ##4636# (digits may be wrong)and switch some settings in there.

Nothing of the sort fixes the issue.. I'm gonna try reflashing radios.
I'm on 1.15, S-On, HTCDev unlocked, CM10.I have the same issues.
When i reflash the kernel, LTE will work for several hours, and then I get the gray bars of doom. Oddly, I still get a data connection with some apps (Reddit Is Fun, etc.), even though the phone shows no data. It's been so frustrating that I've considered going back to sense...

Yeah that's exactly what happens to me.. and no matter my attempts to airplane mode the phone refuses to connect to 4G LTE data after a few days of reflashing.. So odd.
Just clean flashed deck's most recent build from IRC (9/19?) and I'm having the same problem as before. This time it didn't even make it an hour before LTE went away.
And after searching around, apparently we're the only people in the entire world experiencing this issue.
I wouldn't say entire world because there's isn't a worldwide supply of evos lol

I.E. His statement still stands because we would still be the only people in the world having this problem..
I am honestly stumped as to how to fix this.. Sprint support can't help and I sat in the irc and people would tell me to force lte mode in network settings.. Doesn't work.. Because even though I get data connection.. I then lose the ability to call and text.
I tried paranoid, cm10, and aokp. I couldn't get lte on any of them. And phone calls were at max volume, distorting the speaker even, no matter where the actual volume indicator is.
Went back to a sense based rom and no problems.
1.12 panda hboot, s-off'd, with the new firmware.

I'm too hooked to cm10 to switch back now lol. This is unfortunate..
I'm having the same Issue. Seems to have started with a Rev of CM10 around the beginning of September. I have been running a Sense ROM for the past few weeks, but I check in every so often to see if deck's made an update. Nothing has worked so far. Anyone have an update or solution to this problem?

I am having the exact same issue as you with the "Greg bars of death". I had good consistent 4g at one point in early September (possible unofficial 9/6 build based on saved speed tests) but not since then. I have also found that having LTE off gives me more reliable 3G data.

[Q] Issues connecting to mobile networks CM10

I flashed CM10 with TWRP a few weeks ago and my phone has since developed issues connecting to both mobile networks (3G/LTE) and wifi. Sometimes it wont connect to 3/4G at all and often when I get home it takes absolutely forever to connect to my home wifi. I have baseband 1.12.11.0809. I'm going to wipe and reflash tonight, but any ideas what the problem is?
Known issue with CM10/CM10-based roms for some users. Only way to avoid it is to stick with roms based on stock sense ics

Try reprovisioning the phone, flash a sense Rom get your msl and dial ##72786# and enter your msl. Go to menu, press reset, then flash back to cmx
cant conect to 4g
I have 4g where I live and I can't connect to it
There's issues with ehrpd and now I'm pretty sure its more of a sprint issue since I have seen connection issues on 3 different LTE phones. On all three toggling airplane mode gets the phone to jump over to LTE

I tried everything I could think of and nothing worked I ran Paranoid Android for a week with very few network issues and then just ran into a brick wall. I tried everything as far as updating prl/profile and using dialer codes and even jacked it up to where I had to ruu and unroot to be able to update my prl. Since then I've never been able to run an aosp rom without some data issues. I've ran Meanrom as my daily ever since with no data issue.

Borked 1x antenna?

Recently I have been experiencing, like many others, difficulty maintaining my 3g connection. It drops out at random times, sometimes staying off for 18 hours at a time regardless of reboots, flashing different roms, resetting my phones profile or reactivating my handset.
One thing I have noticed though, is the fact that my phone never goes to 1x. Ever. It's either 3g or nothing.
Do my questions. Is there a way to test the function of my 1x antenna if it is indeed separate from the 3g antenna?
If they are not separate, is there a way to reset it in some way?
I am currently running the latest radios from The good Capt. Throwback, my thought was to downgrade them and see if functionality returns.
Any ideas on how to proceed after that would be appreciated.
Mr. B.
ETA: running Jamie's latest PAC and have run PAC and RootBox almost exclusively. Stock kernel. No tweaks. Flashed latest radios about 30 days ago.

Jeezz...I had almost the exact same thing happen to me the other night...I had chalked it up to messing with a torrent app...but out of no where I lost my 3g connection, and it went to 1x...and the 1x would also cut out leaving me with nothing at all every 5 mins or so(the weird thing tho, is when the 1x connection would disappear I would lose the 3g symbol but in the network type it would list EvDo now...but I would not have any connection).
Naturally I was crappin my pants lol, I can't use the update profile feature on my phone, it's on Boost. So I went ahead and flashed the phone over again...Still the problem was there....So I did a factory data reset....still the problem was there....finally I went ahead and did the ##786# factory reset, flashed the phone again...Finally I was back on evdo like normal.
(BTW, my Evo LTE is now running 4.0.4 stock and there happened to be two of my friends here with their flashed to Boost Evo's, which were all running on EvDo with no issues...Plus I fired up my OG Evo 4g that is also on my Boost account and it was running on EvDo no problem whatsoever....so I knew this was some crazy issue with my Evo LTE)
I'm just glad the hard reset fixed it, I've been paranoid ever since though checking my network status, making sure I'm on EvDo lol.
Thanks for the responses. I've tried every reset I can find. Flashing the older radios didn't help either.
At this point, I'm just trying to figure out if the 1x radio is functioning. At least I wouldn't completely lose my data connection when the 3g drops out.
This happened to me when they were doing tower work in my area. Lasted a few days then I had 4g in areas I never did before.

I can only hope that's the case, Thick. It would be the best possible outcome.
By the way, thanks for the kernelly goodness.
It's the most likely cause, sprint has really been stepping up the rollout, in less than 2 months my lte coverage has practically tripled
could be eHRPD switching, I know deck got it all fixed up in the cm10 nightlies.....are you in a LTE area?
if not try setting mobile data to just CDMA and see if it sticks. I had that issue on the early cm10 builds where it would try and switch and just drop data completely.

My area in Jersey is on the short list for LTE activation in the short term, so there's a really good chance of this being the case.

My confusion comes from not having 1x coverage where I used to have it. Is that coverage dropped once LTE is activated? That would explain my issue.
I have read up on the eHRPD handoffs being an issue, but since I don't have LTE coverage at the moment I ignored that as a cause. I'll check out the newest Deck build and see if that helps anything.
Thanks for the help.
