Problem with network set to auto gsm/wcdma

I'm having problems when my network is set to auto gsm/wcdma. The phone will get stuck when it switches and I lose service. This has been going on ever since I rooted my phone. I've tried several different ROMS, with their suggested radio flashed and the only way I keep service is if I manually set it to gsm mode only. The problem with that is the internet incredibly slow, which is annoying. Is anyone else having this problem? I'd like to be able to just use the phone without having to worry about losing service.

haven't had any issues with losing service or constantly switching between 2 and 3g.
have you tried managing your apn settings?

select "prefer wcdma" in apn settings

Preferred network mode is what you're talking about right? I'll put it on WCDMA only and see if that does anything. I'm pretty sure I've tried this before though.

Only thing I touch in there is what I've said above.

Tried using wcdma only. Then my friend called my gfs phone and asked for me. So back to slow internet and gsm only. I'm about to smash this phone and get it replaced by best buy protection plan. It would be nice for the phone to work without having to do a bunch of extra things.

He said he called me twice, the phone was in my hand the whole time and never rang.

Why does he have your gf's number in the first place?

I had a similar issue here in San Francisco... I believe it's because we're in an area with a 850mhz and 1900mhz overlay. I kept bouncing back and forth between the two. Some areas such as South San Francisco and crossing into the East Bay I'd bounce between "H" and "3G" ... and voice was a mess.
The way I got around it was to completely restore to off-the-shelf condition, and then re-root, re-flash the stock ATT rooted rom, and my problems vanished.
Even when I had my iPhone I had to reprogram my phone to prefer 850mhz here in the city, and manually switch to 1900 when I'd leave the city. AT&T's implementation of the intertwined 850\1900 in san Francisco is still fairly young, and it's pretty bad.

So to do that I would just flash the stock ATT Rom, then re do the whole root process and then flash the rooted version of the stock rom?

Oh, I've already tried to do that. I just leave it in GSM only mode and it has no problems, except slow internet...

I just tried flashing the ROOTED stock rom, no go. Changed APN settings, nothing. Now after trying to restore backup of revolution 4g rom, clockwork locks up and I have to boot back into this stockish rom. And the internet works. WTF I'm about to just smash this phone with a sledge hammer, get it replaced by best buy's protection plan, and leave the new one stock.

I've noticed this multiple times, on different ROMs/radios. But tbh, I've noticed it on my last 3 devices with ATT as well. There are times, usually when bouncing back and forth between networks, where I just can NOT call out, and when I call my phone it rings on the calling end, but my phone never rings. I've chalked this up to ATT sucking... I've learned to live with it, if you need me that bad leave a voicemail and I'll call you back.
Also - There are multiple times that I've called my fiance (who has an iPhone 3GS) and it's rings on my end, but never rings on her end. This tells me that this problem is DEFINITELY not device specific

:| I hate AT&T

Data connection dropped for no reason

This is starting to bug me..... for no reason the 4g connection and even when I turn off the mobile network, wait a few minutes and turn it back on, it still wont work until I reboot the phone. Sometimes rebooting it doesn't work and I have to pull the battery.
Anyone know whats causing this? When this is happening I see the ^ arrow on the 4g connection lit up like a christmas tree but nothing is uploading and theres no data connection....... HELP!

Mine dropped Last night for the first time. When I first got the phone it flip from 3g to 4g at my job. Last night finally went dead. I rebooted and still no network. Then I used the new LTE switch to keep it @3g only. It worked.

when i bought the phone, it is very easy to get 4G in my home and work
and recently, I only can get 3G in home and 1x in work.
and it is not stable, very easy to drop.

Yea sometimes 4g just hangs and it wont step down to 3g...... forcing me to reboot or hard reset .....

Hey Stoneskin,
I live in Hawaii and I have the very same issue as well. I picked up 4g easily in the "so called" extended 4g coverage region when I first got the TB. Then about the middle of last week, poof, no more 4g except for in the true 4g areas. My thought is because so many people were having 4g connectivity issues in these extended area, VZW simply stopped allowing it as a troubleshooting measure that apparently is still going on. I brought this up to VZW tech support and they were clueless as usual. I also posted in the VZW Community Forum hoping to get an answer, but none thus far.

you could try dialing ##778# and pressing send, select edit mode, password is 000000 and then under modem settings change it to rev A. then press the menu button to save and reboot. it has helped me out in the El paso area. friend showed it to me the other day Far as i can tell is that it disables the new network that allows voice and data at the same time since that's the only difference i have noticed other than not loosing my connection anymore. I just a heads up this does not work on the latest version of virus rom RC1B3 sensless but did with previous version and several other roms i had tried

Thanks for the tip, but it didn't work. VZW must have changed something to where extended coverage area no longer get 4g. Only those in true 4g areas. I really think this has a lot to do with the folks experiencing the constant drop 4g issues. They must have rationalized that if the extended area for 4g is not up to par and forcing 3g would be better. Only way I can explain it. From consistent 4g to only 3g. I sure miss the speeds.

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.

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?

[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

[Q] I cannot use my 4G network?

Hello,
I have recently downloaded GummyCharged GBE 2.1 and the theme ICS onto my Droid Charge. The problem is, I have noticed that I cannot use my 4G network, even after I continually tap on it.
I have come up with some probable answers that I still need help with, but I think I downloaded ED1 and not EE4?
Is that correct?
I can use my Wi-Fi no problem, just the 4G network I can't use. So if I want to use my 4G again, I have to root my phone again?

You have a 4g device shouldn't matter ED1,ED2,EE4. You getting no 3g/4g at all?
When you go to setting/wireless networks/mobile networks is packet data checked?

Yes, packet data is checked and I cannot see the symbol for 4G on the status bar. I have no idea why it's doing this.

If you are using wifi your 3g/4g wont show up. Make sure it is unchecked. Also you can use wifi but if in airplane mode your 3g/4g wont show up. I know most of this is simple but trying anything.

Hi,
Airplane mode was never checked. I also don't leave Wi-Fi on when trying to use 4G, so I guess that's not the problem.

No he is saying Verizon network may be down in the area. Over the past well just say the past they have had outages with no coverage. Could call Verizon and see if they tell you the truth or reflash.

My area has 4G coverage, I think I need to reflash.

Try flashing again doesn't work then my guess would be similar is fried or data is really down happened to me too cs said it was fine went to a physical store and all if there phone were down so yeah best of luck to ya

Don't remember the whole thread but have you tried a different sim card? Doesnt that control 3g/4g and if the card is fried you won't get signal? Just an idea that might be easier than flashing something else.

True but sometimes the store reps know better than call center about data outages

Damn, I guess I'll reflash. Do you think it's because of the GummyCharged GBE ROM? Because I was in a rush flashing it but I remember I didn't root my phone first and I didn't flash Voodoo. Before I reflash, no one knows how to fix this problem?

when i flashed gbe 2.1 i flashed the odin version first like 1.7 or something then voddoo was enabled then i booted into recovery flashed 2.0 voodoo already enabled then i flashed 2.1 ontop of it because it is a addon package not a full rom and i was good to go on i side note just back up flash something like humble just to see if your data works if it doesn't work on humble then you know verizon doesn't know **** and data is down or your sim is fried but i would think you wouln't be able to make phone calls if that was the case or make sure you have the most recent radio sometimes that might work sorry if i couldn't help more let me know if you need more help or questions... good luck man

I fixed the issue,
I just went into recovery mode and wiped my data, cache and Davlik cache. Then I installed ICS again from my SD card and the 4G started to work once again.
