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!

How to at least get 3G back for now while verison works stuff out.

If your someone whos stuck on 1x this will at least get you back to 3g.
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose enable-->hit the menu button on the tbolt and commit changes
Update:
So to answer the question of should you change this back?
The default setting is eHPRD which is verizons simultaneous voice and data 3G network. By hitting enable your switching your phone do EVDO or Rev A is pretty much their older 3G netowrk. The info is yours now you make the call of weather you should or shouldnt
To Revert back once everything is fixed:
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose eHPRD-->hit the menu button on the tbolt and commit changes

So is this a network problem or a phone problem because of flashing radios?

Actually I think it is just 4G. The reason our phones lose 3G as well is explained in this article.
http://forum.androidcentral.com/htc...blems-3g-data-dont-hard-reset-read-first.html
The issue with not getting 3G can be fixed by following the instructions in the OP.

It worked on my phone, although it did take a minute or two once my phone rebooted before the 3G connection started. That was probably because I am in a building that actually gets great 4G coverage, but spotty 3G coverage.

If you want to do voice and data at the same time over 3G yes.

Thanks for this. I was beginning to think it was the rom I was using.

I wish i'd have seen this sooner...I thought it was the ROM as well and unrooted my phone this morning just to find that wasn't it. CS informed me there was a nationwide outage after the fact (I have been stuck on 1X since yesterday)
Quick question - I was so quick to try this that I didn't pay attention to the original settings of the phone does anyone know what they are so I can revert back when the system comes back up?

eHRPD Network and Software Upgrade

Just got word from verizon that the eHRPD network is back up, and the software upgrade has been pushed to 10,000 devices. i got both. lets see how it goes!

in 3G areas it slips into 1xRTT.

Not me. I hbooted the old leak today and noticed a very smooth transition from 4g to 3g.

Yes, I'm running the latest stock.
the problem isn't with 4G or the transitioning from 4G to 3G either.. the problem is when you are in a 3G area with eHRPD setting.. you get frequent "Network errors" and 1xRTT.

EHRPD in 3g areas today resulted in lost texts and calls...people said they got network failures when texting me and couldn't get through calling. Forcing revA and all working

This is kinda O/T but I don't think it requires it's own thread: for testing purposes, is there a way I can force my device in to 1xRTT?

Hurray!
Hurray for updates. Let's hope they fix that garbage collection issue so I can tell our shopsavvy users that their phone is supported and it can stop crashing constantly.

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...

waiting it is...thanks for the info

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.

No 4G since the update

I applied the update late Friday night and have not been able to get a 4G signal since. I'm normally in a strong 4G area and had not had any problems like this in the past except for the nationwide outage of course.
I've tried battery pulls, toggling LTE off and on and even did a factory reset. I then talked to tech support and they did a few things on their end that were unsuccessful. They then told me to get a new SIM card but once again, no luck.
Tech support is at a loss to explain what is going on and has escalated it to the higher level of support. It can take up to a week for them to get to a ticket so I guess I'm SOL until they take a look at it.
Anybody else having 4G problems since the update?

I haven't applied the update but have been stuck in 1X all day as well. I also pulled the battery, switched back and forth on Rev A, and toggled LTE. Nothing. Was going to revert back to a saved ROM next. My wife's phone happily receives 3G.

Did the update Friday night and 4G is as strong as ever.

My 4g is also working. What is weird is when I loaded a ROM I lost all signal. I loaded another Rom and nothing. I had to load radio file in hboot and I was back in business.

yea in such circumstances I had reflashed the radio and it works just fine, give it a shot

Received a replacement today, popped in the SIM card and am back to 4G. No idea what happened but the update is definitely to blame.

Yeah I got mess up too with the new update. Had to get a new simcard today and it work ok.

4G working just fine for me also

glad you got it worked out. I would have reflashed just the radio to try and fix it.

Having this issue as well since yesterday (7/11). Loaded Th3ory 5.0 with the newest radio to two different Tbolts (mine and a coworkers) and we're both experiencing the same issue. Flashed different versions of the radio, including the newest one again and had 4G come back for a short period of time before all service was gone again. Not sure if its an issue with Th3ory rom itself and since I cant post in that thread until I make a few more spam posts about nothing to get my post count up, I figured I'd post it here.
in Mid-town NYC where 4g has never been an issue before.

I should add that I wasn't rooted.

What happens if you're Rooted and running a custom ROM and you do a SIM Card pull? I really want to try this method, but i'm scared this will force my phone to download the new OTA update and that i'll either brick my phone or run into some serious issues.

I have had trouble for the last two days getting 4G, never had a problem before.

don't think anyone else is having problems. Might be network issues in your area. Just flashed gingertheory 5.0 yesterday with the new stock 2.0 radio from the update and no problems.

I am having the same issues 4g is gone and only stuck on 1x

Make sure you check your sim and battery cover.

You dont need to pull out the sim card, pulling the battery is good enough. All it does is update the PRL.

I'm in the same boat.... I used to get 3-4 bars of 4G service at my home, now after the update I barely get 1 bar of 3G service. I have to force the phone to lock onto 4G by choosing LTE only.
