[Q] 4g issues - Thunderbolt Q&A, Help & Troubleshooting

I have tried multiple radios and roms but with no success. It's always the same issue. I can get 3G working fine. But once I turn on 4G, if I look in the radio settings, I can see it constantly switching between LTE and Unknown for the network type.
I've tried running fix permissions, on multiple radio/roms. What else can I do? I really need some help. If I can't find a solution I'm going to try and have the store replace it for me after unrooting.
This is my 3rd day of this issue. Could I have changed a setting somewhere unkowingly? What should I check and what should I troubleshoot?
Any help would be MUCH MUCH MUCH appreciated! Thanks in advance!
And before someone says search, I have scoured everywhere I could think of and in as many different ways as I can. I really need some expert help here!

Fixed!
I had a moment of clarity and remembered when I started having issues. Flashed cm7 rc.6 and checked my network settings. At some point I think I turned off National Roaming. Which I think was On before I was having issues.
Flipped the switch and restarted and viola! 4g is back and stable.
I was wrong! It didn't fix anything. I flashed to bamf 1.7 and the 4g issue continues. Help!

This may or may not help. I was having 4G issues as well. I was only getting 1X or 3G for days with an intermittent flash of 4G. I took another person's advice on here and I removed my Sim, booted without the Sim, and then put it back in. I have been in 4G since I did this.

The LTE radio app is helpful for fixing 4g issues. 1st switch to 3g than once you have it than change setting to LTE. That has worked for me in the past. Also make sure batt cover is on.

Thanks for all the input everyone! After 2 hours on the phone with Tier 3 support, flashing my phone, removing sim, privisioning my phone, resetting the network switches in my area and syncing multiple things on their end.... Nothing changed. They said is was my device and I'll have a new TB and sin on Tuesday! Lol
Thanks again!

[Q] Mobile Data Drop - Not Suspect To Outage

In the past two weeks, my mobile data has been down. I don't believe it to be an outage in my area due to the duration of the problem, and the inconsistency with other Verizon Wireless phones. I was running Juice Defender for a while, and every now and then I would notice that the Mobile Network would drop. Toggling the Mobile Network would not fix the problem, either. I usually cleaned out my cached data for the Juice Defender app, turned the app off, then toggled airplane mode once. (Sometimes just toggling Airplane Mode wouldn't fix it, therefore I had to clear the cache for the app.) Now this fails to work. I cannot get my mobile network to connect by any conventional means. When I receive MMS messages, my network will connect long enough to download the attachment. Also when I do a search for a Software Update, it connects just long enough to tell me there aren't any updates for my phone. I've tried updating my PRL with *228 and I've even tried *18 from a post over at Droid Forums. Neither work. I've removed the battery and SIM Card as suggested in some other threads here at XDA. I've also removed the Juice Defender app.
The phone is not rooted and has never been rooted with the Temp Root methods. I'm not opposed to rooting, but if I root, I'm gonna perm root and I would rather not have to factory reset my phone if I don't have to right now. I'm mainly posting this because I cannot find anyone online with the same issue that I am having. Any help would be appreciated. Personally, I think its an issue with Dalvik-VM. I can attach a copy of my LogCat if needed. Any ideas on my issue? Thanks in advance!
Check your power settings, if you are in economy mode it will mess with your data connection.
I have a paid version of JuiceDefender, it has caused me so many problems I don't even bother to install it anymore.

I also have the same issue, tried a couple basebands and could not fix it. I ended up not using it...
Every once in a while my mobile network or just lte somehow gets turned off and I have to turn it back on, but that's rare.
I tried juIce Defender and also had problems losing my connection so I uninstalled it. Plus the settings were so confusing to me. I'm using Green Power now and that seems fine.
You didn't mention mhs so I assume you're not using it but that has known connection issues.

Did you ever try doing a factory reset? I'm curious to know if that will fix it.

Juice Defender gave me fits, too. I'm not using my phone as a Mobile Hotspot, either.
I kinda think its my ROM. I'll play around with some stuff, or I'll just get around to doing a factory reset and see if that fixes the problem. I'll post any solutions here for others.
Are you in a good 4g area? If you scroll down the general section here, you will find my topic. If you use 3g more than 4g, there is a post in that thread about##778#. It helped me. Sorry if it doesn't help you, Cheers.

I just wanted to let you know that I'm having this problem as well. I AM rooted and running CleanRom, but my daughter has a non rooted Bionic, and both of us suffered a complete loss of data today. My husband's rooted Rezound is fine.
I took my phone into Verizon today, and after initially just trying to swap out the phone (which I wouldn't allow them to do, it took me too long to get my phone the way I want it), they finally switched out the 4G sim card, and the data came back instantly.
When my daughter leaves school today, she will get her 4G card swapped out as well, and we'll see if it is in fact a network connectivity problem.
It seems to me that our 4G phones has a lot of trouble switching from wifi to 3G/4G service.

I will +1 this. My work WiFi is spotty, and so the phone falls in and out of WiFi. The Rezound HATES that and usually leaves me with no connectivity. There is definitely a WiFi->Mobile Network issue.
Try doing a factory reset. Could be a bad device... Im getting amazing reception on mine. I havent even seen my 3G or 1x icons yet. Constant 4G lock.
Forget what I said, my data connection has been dropped again for the past thirty minutes and there's no way for me to get it back.
I'm going to try a factory reset. I *really* don't want to have to send my phone back because my husband is getting amazing coverage on his Rezound. However, we're still in the first week of our Verizon contract, and if this looks like it will be a standing issue, then we'll have to cancel and go crawling back to horrible Sprint.

I think I'm going to try doing this. How painful was it for you to convince them to give you another SIM Card?
Edit: Just read your last post. Please let me know what a factory reset does for you.
They had no issues at all swapping out my 4G card, they certainly couldn't let me walk out of the store with no signal. They knew they had to try something.
The factory reset on the phone appeared to work. I've been steadily switching it from wifi to data, and the data signal picks up, albeit a tad bit slow. Only thing is, I still don't really get 4g, while my husband's Rezound has a great signal.
I got insurance on the phone, so I'll put up with it as long as I can before I start screaming at Verizon.
Good to hear. I'm going to try to switch out my SIM card today and see if that fixes it. I thought maybe it was something with the ROM, seeing as how my 3G will turn on whenever I need to send an MMS message, so a factory reset made sense to me. I just don't want to do it. Lol. Thanks for the info!
I've experienced it twice in the last 24hrs and it just happened to be right after I installed and used LTE OnOff. Don't know if there might be a connection there. I keep forgetting this phone has the ability to switch 4g/3G unlike the TBolt. Needless to say, that app is no longer on the phone.
KORM via the beast known as the Rezound.
I had an issue with the mobile network just dropping in and out (other people in the room did not lose signal). We currently don't have 4G and it is 3G only. I did a factory reset of the phone, but it continued to occur. Took the phone back to Verizon store to exchange it (it was 1 week old). At first they weren't going to and gave me a run around but in the end exchanged it. Have had no problems with new phone.
My girlfriend's Bionic keeps dropping 4G more frequently than my Rezound. I get this problem too though. Usually a toggle of Airplane Mode fixes it...but it's pretty damn annoying. Happens once or twice a day!
A Factory Reset fixed it. Everything went smoothly, too. I backed up all my SMS Messages with HTC's Messaging app, and got my network back as soon as I restored it and set everything back up. Hopefully this will help anyone else who might have had the same problem.
I've been side by side with a fresh Rezound and watched both of them jump from 4g to 1x to 3g and sometimes never 3g. The problems were a million times worse with my droid charge as it's a combination of the handsets and the towers.

Hmmm
I have this happen if I am in an area with NO signal (such as the basement level of my office building) for long time. Only a reboot will bring back data. Does not happen often (maybe 2ce in a month and a half).
I am intrigued by the person who blames the install of LTEOnOff. I have it installed but do not use it. Maybe if I ever have to hard reset (such as if ever run the unlock), I will not reinstall that program.

[Q] 4G cutting out since 6/4

Ever since around the 4th my 4g has been acting up like crazy. I live in Hollywood so I don't think it's a verizon issue. Has anyone else been having problems? I'm thinking maybe it was from an app update with a glitch in it? My phone is totally stock but I have around 400 apps (I know, too many, I can't help it...) I've gone through all of the app permissions looking for an app that can change my network connections but no luck so far. I know this is kind of a shot in the dark but if anyone else had this happen and figured it out that would be great. I'm open to suggestions.

The My Verizon App was recently updated (and removed the homescreen widget, so I didn't update mine), so that might have something to do with the problem.
Does 3G work fine?
I have been having this same problem, so is a friend on another device. When we switch to 3g, 4g never returns unless airplane mode is cycled.
My my verizon app is up to date but I still have the data widget. I haven't updated the "location agent" one though. I'm not sure about the 3g working...the 4g symbol just comes and goes so fast I don't think the phone has time to switch onto 3g. It doesn't happen 24/7 but when it does it's like a non stop cycle of on and off (like an app struggling to do something)..

So my daughter just recorded a 10 min video on its a small world. Next time I check my phone I have no 3 or 4 g just bars. I don't think anything of it until I'm elsewhere and my wife has 4g and I don't. I cycle my 4g widgetsoid and get service. Screen off and on and no Vs again. Airplane mode, same problem. Finally I put it in airplane, powered it off and did a battery pull. It's fine now.
I've tried turning the phone off, fully restarting it, pulling the battery, and cycling through airplane mode but I haven't tried pulling the battery off after powering down while in airplane mode though (that was a mouthful). Maybe that's the magic combination... I'll give it a shot and see what happens, thanks. I'll post if it helps out or not.

Had the same issue sporadically. Only app I've added since then is Firefox beta but seriously doubt that is to blame.
Actually had this issue this morning for a bit, then resolved on its own.
I have been having the issue of my 4g randomly dropping, 3g not kicking on (just signal bars), and the 4g coming back when it feels like it.
I did a battery pull, cycling the 4g, airplane mode, etc. and still having the same issue.
This started around Verizon's useless upgrade.

So far so good since I did a battery pull and let my phone fully boot while in airplane mode... Only time will tell..

I haven't had 4g since I rooted....so I am a little worried...
I also have had the worst 4g service the past week or so. I have a htc rezound and live in the suburbs of Detroit, MI. I have tried everything under the sun but cannot get it working. This is obviously a Verizon issue, because it started happening out of nowhere. I didn't download any nee apps or change any system settings. I don't understand why this is happening. I do not want a refurbed phone so I will not send mine in for a replacement. I'm sure that wouldn't even fix the issue. Verizon needs to get to work and figure this out.

My 4G is fine and I'm rooted and running a custom ROM (Ineffabilis 1.4).
Have you checked if 4G is enabled in your settings?
(Search for 4G toggle in the Play Store)
Some people reported that their phone disabled 4G in the settings for no reason.
Everything was fine for a couple days then all of a sudden it started acting up again...I have a feeling it's the new draw something free app...maybe..

Lol apps do NOT cause data to cease or "hang". It appears to be Verizon as I have been having 4g issues on stock gb and ics.

Same issues here (multiple ROMs). 4G has been sporadic or non-responsive and 3G is about as bad. Started a couple weeks ago. I have tried hard resets, ROMs, firmware updates, etc and nothing.
Good to see I'm not the only one.
Any other Verizon devices that can confirm this?

Ok, so I've had the issue that the OP is talking about since I got the phone like 5 days ago. Since I wasn't rooted (and still aren't) I decided to call Verizon about the issue. I've talked to multiple Verizon techs and after they had me do basic steps, like checking wireless networks settings. Nothing they told me I hadn't tried myself already prior to calling them. I even got a replacement BRAND NEW rezound and sim card and am still having the same issue. I have decided to try and figure it out myself and have been running various logcats to try and narrow the issue down. Problem is I don't really know how to read these logs too well. If there was someone who has more knowledge in reading logcat logs id be happy to upload or send them to you if you think you can help. Any help in resolving this issue would be awesome as Verizon seems to be unaware of the issue up until now and I would like to resolve it before I root. I'm going to give them a call tonight and explain some of my findings to see if they can give anymore input or get me to a higher lvl tech.

According to my findings, it very well could be. I'm thinking it may have something to do with vznavigator. But don't quote me on that as from what I said before, I don't know how to read logcats too well.

[Q] 4G connection but no data

For the past 4 days or so my phone has been able to "connect" to the 4G network but I cannot receive data over it. However when I switch the phone to 3G only data works flawlessly. Calls and SMS works fine but the browser and any apps that use data say no connection. The connection icon is grey instead of blue.
I've been running CM7.1 on the thunderbolt just fine for months but I decided to use another ROM just to be sure. Put thundershed 1.6 on today and for a while 4G worked but it died again. was using radios 1.48.00.0906w_1, 0.01.78.0906w_1. Thought it may be a problem with those so I flashed the just-released 1.49.00.0406w_1, 0.01.79.0331w_1. No change.
I've gone through all the other troubleshooting steps too, hard/soft reset, battery pull. reseat SIM card, toggle airplane mode, switch off the LTE radio, etc. Called verizon and they confirmed I have a recent PRL.
Anybody have thoughts as to how I can fix this?
i've been getting in and out data connection with the newest radio on my thunderbolt atm...i'm starting to wonder if its the phone itself
I don't think its anything we can fix ourselves. So many people are having problems similar to this that it must be verizon. I had exactly the same problem you are talking about and I can get it to straighten out by turning airplane mode and taking it back out.

I really hope it is verizon and not my phone, but I've talked to them probably 3 times in the past 2 days and no one has even hinted that they are having network problems.
So right now I guess I just have to wait it out. Man I hate streaming music over 3g...

Update on the situation - My 4G data is back after about a week.
Looks like I was temp banned from Verizons 4G for using too much of my unlimited plan. Can anyone confirm this happening to other people?
Thats what I suspect at least, it could be a coincidence and their 4G tower in my area was broken for almost exactly a week.

dropping from 4G to 3G

I keep finding my Verizon Note 2 has dropped from 4G to 3G. Nothing I do changes it back (tried to switch data modes, toggle Wi-Fi, etc) except a reboot.
When I reboot, 4G is back no problems, but it's a pain, and I can't figure out why it keeps doing this.
I would like to think it's a Verizon network issue, but 4G is right back when I reboot, so it's not like a network outage.
Has anybody else had this?
Is this a flaw with my radios? Any other suggestions?
I'm stock but rooted.

Stock roooted too, somewa of the sae issues.
At home, 4g is inconsistent, but when I have been in strong 4g areas, I have noticed it does not like to connect. I enable, then disable airplane mode and it works for me to get it into 4g.

Have you found any resolution to this?
I purchased a Note II from LetsTalk that was acting somewhat similar. It would sometimes go into 4G, but performed horribly. Also, it would stay most of the time stay in 3G even in areas where for 4G is strong. I was using a Galaxy S3 to compare. A lot of times, going to airplane mode, and then back out would get into 4G.
I even went to a Verizon store to do a SIM swap. That really made no difference, and I chalked it up to the device being defective. I have since sent it back to LetsTalk and awaiting a replacement.

hey sorry so tardy in my response.
yeah, my issue was resolved, I think. I haven't experienced it in the last few days, and come to find out Verizon seems to have added 4G to our neighboring city, so I think that's what was messing with my 4G, while my 3G was uninterrupted.
plus, I've since unlocked and flashed beanstown's rom, and that seems to have a great signal/ gps quality

Loosing connection constantly

Lately I've notice wifi signal dropping. I started to notice when youtube gave me network errors, wasn't a big deal I just clicked try again until it work, but now I am noticing in facebook and whatnot. I am browsing XDA and suddenly I lose signal. This is happening on data as well. Sometimes I am on LTE 1 bar when I magically switch to 2G and stays there for a while even when the area is 4G. I read somewhere here about it and it turns the cases are blocking the signal, well I removed my case and it didn't help. However, a month or so, this problem wasn't happening, even with a case. You guys have any idea?
This happened to me the entire first day I owned the one. I even put a ticket in with HTC. They were going to have me reset everything, take my password of my network and unsecured it. Next day I got home and no problems. Stopped using power saver though, also make sure that wifi stays in during sleep.

I guess I will check it out with out Power saver though and see how that works
Just replaced my phone under warenty. Could only get 4g on wcdma only setting. I was missing calls without it showing in call log. My WiFi was increasingly getting spotty. I tried resetting the phone with T-Mobile tech's but it wouldn't help. Still testing the new phone.

I don't have Tmobile warranty since I bought it new off ebay. But I haven't unlocked it or anything yet you think I should contact HTC about this?
I'd call T-Mobile anyway. I think I remember that they honor the warranty of any of their new phones as long as yours is the first SIM ever used in it. Can't hurt to try...

My wifi has been great, no problems. But, recently my service has been crappy too, my connection would drop from 4G to 2G and when I was trying to send a mms it kept failing, even though it said I was on 4G LTE. I did flash my radio to the newest, but did not seem to do anything.
