4G Problem

I'm having a problem where my phone will not connect to 4G, it connected fine for about 2 weeks and then it stopped working. I have tried everything I can think of, restores, data wipes, new roms, the new radio, messing with modem settings, but I have had no luck, I'm starting to think that it is just my Thunderbolt and I will have to get a replacement I took this screenshot of the thing i think is werid, the phone recognizes the LTE network but GPRS service is disconnected. If anybody has any suggestions on something for me to try it would be greatly appreciated. Thanks

Flash the new radio that was made available today and see if that changes it. If not factory reset your phone and bring it in and say it stopped working.

I been have problems with 4G since Saturday here in San Diego. It has been working fine for 3 weeks up to this point. I have 3-4 bars of 4G, but there's no network connection. The connection does NOT bounce between 3G/1X. It is solid 4G, however on the 4G LTE icon at the top, only the white arrow lights up, never the down arrow. When I run the ping test in the diag screen you posted there, it fails.
I went down to the Verizon store near my house and they had two display Thunderbolts. One of them was having the same exact problem as mine. While I was there, I rebooted mine and it magically started working right.
Then about a hour ago, it stopped working again. Rebooted twice and nothing. Called Verizon tech support just to let them know there might be an issue since my phone and the display phone werent working right. They transferred me to a
"4G specialist" who had me shutdown the phone while he "rebuilt" my account in their system. Booted back up and it works again.. Dont know if something he did fixed it, or the third reboot fixed it.
BTW, my phone is factory stock. Have it set to LTE/CDMA Auto in th phone settings.

Sigh... it's doing it again this morning

Same here, stuck using 3G until further notice.

Ya this problem is making me mad, I'm going on a trip, and when I get back if I still have problems I will just unroot and get a replacement, I really hope someone knows a fix to this though and posts it

My 4g and 3g have been on the outs today here in ohio. Never had the issue before today. I'm assuming its a network issue and not an issue with my phone. And I have the new radio fyi.

-89 dB is pretty weak. -89 to -93 is what mine is at most places in my house. The only way it will go from 3G to 4G is if I walk over to the bedroom window facing the nearest celltower and then it will go to about -78 and switch to 4G.
When facing the tower do not "cup" the phone because I have seen as much as 10dB loss from my hand being between the phone and the tower.

I can say the same thing in Phoenix.... you have good 4g days and you have bad 4g days. Like yesterday... up then down then up then down then nothing for an hr.... then up and down... an awesome way to tank the battery.
I wish Big Red would make up their minds... and fix these issues.

Same here in scottsdale, shows the 4g icon but there is no data till it switches back to 3g. Maybe just a coincidence but mine started yesterday after upgrading to the new radio and bamf 1.5

I'm having the same exact problem you are having in NYC and now in Boston while I am on vacation. If I force the phone to 3G, everything works beautifully, but to get 4G working again, I have to power off and on the phone.
Now, while in Boston, this issue happens when I am in an area of no cell signal (say the parking garage of my hotel) and then walk into an area with cell signal. I'll wake my phone from standby and will not see the 4G symbol, and then the symbol appears, but no data, like what you described.
I wonder if it has to deal with how the phone connects to the towers. Maybe the new radio will fix it? I'm currently on stock since it's still runs pretty damn well.
Just to mention, my phone does not suffer from the cycling issue between 3G and 4G.

Switched to bamf remix 1.5 with the same updated radio and 4g works great now. Kinda like the remix better.. win win

Did you try taking out your batter and sim card... waiting a minute and then putting them back in? I had this problem once where I was stuck in 3G in a 4G area and this is what tech support had me do. I didn't think it would work, but it did!

Constant data drops

So I am currently running bamf 1.6.3 and I change kernals a lot, but one thing I can't seem to fix are the data drops. I live in raleigh, so no LTE, and am running the .7 cdma / .6 LTE radio combo. The data drops off a lot, more noticeable when changing towers. Even sitting at home with good signal it will just drop to 1x and is hard to get 3g back without a reboot. Anybody else see this? No reboot problems

So am I the only one with this issue??

Mine drops 3g and 4g for a second or two and then comes back. It has been happening a lot recently.

At one point in time I would have that happen, it was because of a local tower being screwed up. Maybe switch from eHRPD to the standard 3g network? or vice versa?

Had the same issue with 1.6.3 and went back to 1.6.1 and Im fine again. Ill wait for another version before updating again

Having this same problem but I'm on stock and it only happens while I'm on 3G....nothing but problem since I got this phone....did Verizon and HTC test this phone out? Gps problems,reboot problems,data problems,battery...I'm really sorry I left my carrier for this phone.

the NEW 4g network is going to take some time to get running properly and because of that will have issues as will the phones. Not everything works flawlessly off the bat, give time to get everything settled and figured out and it will get perfected.
With all the radio/prl updates they have been doing I wouldnt be suprised if it is caused from that.

I was having the same problem. Disabling eHRPD has seemed to fix it. I still see strange signal drops, but I'm not seeing data drops at all.

It's not a fix, but rather than rebooting, just turn on airplane mode, wait for the airplane icon to appear, and then disable airplane mode. I have the same issue you describe, so I just keep the airplane mode toggle widget on my second home screen panel.
I'm getting very frustrated with the inconsistent data connection on this phone. I halfway considered trying to get VZW to let me swap it for the Droid X 2 when it releases next week.

I have similar problem. I live in Northern CA with 4G coverage. The problem will be like this:
- 4G works OK, data works
- Moments later, 4G icon shown upload activity (arrow up sign)
- Shortly afterwards, no data. Mail, Google Maps, etc. failed
Fix is to turn Airplane mode OR REBOOT the phone. I have tried switching radio mode (using LTE ON/OFF) but to no avail.
I understand 4G is new and so is the phone, but c'mon.. it has been sometime now and we are STILL paying for the service, even when the 4G network is down (few weeks ago) or when the phone loses data.

This happens to me on stock. Will be using 4G and then all data drops, then comes back, then drops, then comes back and repeats the cycle. Rebooting, airplane mode, nothing helps. Eventually it goes back to normal.

My phone went wacky yesterday. 1x and no data for four hours. Spent an hour on the phone with Verizon tech. We did everything possible and nothing. Then it just fixed itself. Had someone with a Droid X in the same room as me with great EV signal. Now the phone is perfect again. I dont get it . I have enabled REV A and now I put it back and that didnt matter.

Mine as well on 1.6.3 bamf remix. i had to keep going in airplane mode. it was stuck on no service or even the 4g icon (not blinking and no service)

We are Guenna pigs....

Since i have gone to the new leaked gingerbread radio not the latest froyo radio but the new gingerbread i dont have data drops
get it here http://www.multiupload.com/KQCRTNALV9

I too had continual problems with data yesterday (on BAMF 1.6.3) in San Diego. Kept switching from 4G/3G/1x. Today seems to be running smooth.

I'm gonna say thank god I'm not the only one, I don't live in a 4g area, yet there's many times my 3g will do the same arrow thing showing up and than everything fails. I'm running the new radio and perfect storm 1.4

[Q] Unable to get 4g

Alright, I'm a flash addict, love trying all the roms and well I was switching from bamf 2.0 beta 4, to Gingeritis VIII. I did my wipes and everything special, yet when I finally load it up, my 4g is not there. I'm in a 4g area, and I can get 3g but not my normal 4g. Not sure what to do, I even tried restoring back to my bamf rom with no luck. I had it before I did the switch and it was working fine. Anyone else having a issue or know what could be causing my problems? Forgot to mention I did try changing the radio settings and doing a fix permissions, neither did anything.

Did you update the radio?

Have you called Verizon to see if there is an outage? My 4g went down for a few hours yesterday, might just be them working on the network.

Radio was updated and I'll give big red a call, I mean its kinda odd I hold my 3g easily yet my 4g dies. I've had my 4g all night, and it did happen in the morning, so maybe they are working on it.

Called big red and they told me it would be back online soon just a short outage in the area. Came back online as I was typing this lmfao

Everyone needs to remember, VZW is constantly upgrading/testing/fixing their LTE network. Things like this will be going on most likely all year as they continue to roll out to more cities/markets. First thing to do if your 4G starts acting up is just give them a call. More likely than not, they are doing work, it's just coincidence that it stopped working right after a flash

Yeah I can't get 4g to work either. It might be because I don't have it yet. I figured I would just flash rom after rom till I find one that works.
Just trying to get past 10 posts.

I am also in a 4G area (Los angeles) and had 4G all the time but when I upgraded to the Gingerbread leak I lost it and yes I flashed new radio, its been about a week now. Haven't called big red yet and also haven't heard of updates in my area but 1 week, that's a long time. I also reverted to froyo with accompanying radio and no change...wondering if anyone else in LA area has the same problem or do I have a problem with my phones hardware...

Be sure to reboot the phone like 5 times. That brought it back for me.

I haven't had any data since friday afternoon. I had it connect to 3G earlier this morning but it promptly disconnected.
I've tried rebooting since friday. Setting to CDMA, enabling Rev A from ##778. Still nothing.
I'm on the launch stock rooted rom.

I called tech support and let them know of the issue, said there is no 4g outages in my area (los angeles) and was instructed to factory reset, which i do before any rom install then i gotta call back-if and when i get this resolved i will post the outcome.

Not sure what rom you're on now, but whenever I flash something if I lose data I have to go into the antenna settings and force 4G for a while and it will pop back up

I'm still on Baseband 1.16.00.0223 and Software 1.12.605.6
Could it be since i'm rooted and have not applied the OTA, that verizon is refusing to authenticate my data (connection)? Because when i look at lteonoff, it says i'm connected to whatever network i specify, (LTE, CDMA - eHRPD OR Rev. A [if i go into ##778])
If I go to options ->software update -> check new, the 3G or 4G icon will pop up and checks for a newer firmware. It tells me there is a new update and i can press okay, defer, or deny. As soon as i exit that and try to use the browser, the 3/4G icon goes away. Should I update to the MR1 OTA?

Im just in a 3g area and everytime I go to a gigerbread rom and radio all I get is 1x. Then reverting started jot even fixing the problem. After about 10 flashes back and forth and rebooting a hung I finally ended up on Froyo with 3g. I'm staying here. Not worth my time to run gingerbread.

I was running a GB rom and this afternoon lost all data.
If I take out the sim card and reboot, I can get data for a minute or two...then it goes again.
I'm going back to stock and taking my phone in tomorrow.

Ugh to the guy that said call tech support to see if there is an outage, I don't work in a call center but do in a store and I hate when people come in or call for outages my suggestion is to follow @vzwsupport on Twitter they will let you know in no time and it keeps you from having to go through the menus and crap.

I re-flashed back to stock and now I've got 4G back.
If anyone is having these problems after running GB I would use JCase's "back to Froyo" flash before trying anything else.

Verizon has had a known problem of thunderbolts loosing its 4g, 3g and 1x. I had the same problem over a month ago when my phone was only able to receive calls and text. Had no data.. so I called them they had me do a factory reset and it fixed it

In NYC and stuck at 1X?

Hello all,
This has been happening to me for about an hour now. I'm typically in good, constant 4G range. Is anyone else having data issues?

i found this: http://www.howardforums.com/showthread.php/1718601-Data-outage-in-Nassau-County-and-Manhattan
dunno how close that is to you but maybe it's not just you.

seems to be back now... let's see how long it lasts, lol

i dont even have 1X...around 2:30 PM went into a subway, turned on airplane mode...once i got out and put my phone back on....no data since...even now still.

I'm in north jersey about 45 mins from times square and i'm on 1x for over an hour now. Hope it's the network and not my phone haha. Sigh.

I was having issues with weak/terrible 4g in my area a few weeks ago. (lafayette Indiana) It was kind of an ongoing thing for awhile, but come to find out that verizon was actually working on the network to expand it across the entire city. Just what was going on in my area and possibly in yours.

just did a wipe on my phone...still no data.
my last resort maybe try different froyo radios? or wait??

No go with Froyo either... I am working out of our madison ave office for the day and I am stuck at 1X. I flashed back to Froyo in hopes to get data, but nothing.
EDIT: I just went down to the verizon store that we have on the street and their Charge has 4G, but their Thunderbolt has 1X...

I still have 4G now... it seems to be working ok.

Just had this same issue in Detroit. Was stuck on 1x for a couple hours. Tried restoring a few backups, rebooting, and factory-resetting + clean flash of BAMF, but none of that worked. It just came back up a couple minutes ago without me touching anything. My guess is VZW is making some adjustments.

Don't know if you were running gb or not, however, I ended up frying my sim card shortly after reverting to froyo. Just FYI. I had the same 1x issues.

I had 4g early in the day yesterday. I switched to 3g, and when i tried going back to 4g i got stuck on 1x ever since. 3g still works but if i try to get 4g i only get 1x.

if the sim card is done wouldnt you get no service at all, not just no data?

Aroiund midnight into the early morning is when VZW does upgrades/work/testing/etc... on their network. Most people are sleeping then, so they do it then, because that is when it will effect their customers the least.

my data finally came back!
i probably could of waited and this be a coincidence...but i turned off the phone, pulled the sim card, turned on the phone to let it tell me "no sim detected" then turned off and put sim back, booted up and i'm good again. whew.
edit: after boot, loaded a web browser, the 4G icon disappeared and my homepage wouldnt load =( UGH

I've had LTE all day (since about 7:30 AM this morning) so my hope is that they are going to do maintenance and restore LTE to my home area (have it strong at work...but they took it away from my house a few weeks ago.) I'm in the Lehigh Valley, PA.

I'm in Manhattan in the Flatiron area and the UES and have been on 4G all day. I'm on Froyo (BAMF Stripped) with the leaked radio fwiw.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

look in your status and see if you still have an IP

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

In the original post, I stated that was one of the things I've done.

have you checked to see if you have an IP address

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
