I had been running an unofficial LineageOS build for a week or so, when I realized my 4G just stopped working, and I was stuck with 3G. I didn't make any changes that I was aware of. I tried a wipe, a reset of network settings. I have reflashed a complete stock image to see if that does the trick... And, no, still stuck at 4G. I've got a logcat of what is seen when enabling/disabling airplane mode, but nothing really stands out to me (and I honestly don't know what to look for).
I have called my carrier, U.S. Cellular, to try to figure this out... They did a few things on their end, had me do *228 and power cycle, and then recommended a factory reset. Since this is a BYOD phone, they won't really support much beyond that.
What the heck happened?

I am helping my mom with her VX6800 for verizon. I first flashed the RUU_TITAN_SPRINT_WWE_3.35.651.2_RS_TITAN_3.35.04_4 350H_SPCS_AM_Ship ROM, just to get the radio from it (If anyone knows where to get the entire Ship ROM with 3.42.30 please tell me, can't find it). I then flashed DCD 3.2.2 and then installed the Verizon carrier cab.
The phone was working right away to make calls, although it still showed Sprint on it, as opposed to Verizon. When i try to access the internet it gives me an error saying "Dialed #777, Cannot connect for unknown reason." I had flashed a verizon phone for a friend before and had to call verizon to get a new code, doesn't seem like the issue here but not sure why i'm not getting internet service and if it has anything to do with the sprint logo showing on the screen..
TIA!!
Sounds like maybe you let the sprint ROM reboot (reset) after you flashed it to get the radio? Check the Titan WIKI on XDA and it'll tell you everything you need to know to fix it.

I have read through the Wiki a few times and it doesn't say anything in there about the ROM rebooting or resetting
"To flash, enter bootloader mode by pressing the power, camera button and then the reset button. The screen should be at a three colored (red, Blue and Green) screen, check to make sure you have the appropriate bootloader. Then plug the device and computer into the USB cable. Start the RUU.exe upgrade program on the PC that usually is provided with the ROM."
I did all this, except not sure if i am using a RUU utility, i just double click on the ROM icon,which i think has the RUU built in. It then flashes the SPrint ROM. if i am supposed to do something after it has finished flashing to prevent it from rebooting or resetting i couldn't find it in the wiki, so if u can just tell me that would help me out a lot...thanks heaps
you let the customizations run... end of discussion...
i think at this point, it'd be easiest for you to flash back to Verizon STOCK and then follow my guide to upgrade it (see signature)..
To flash back to stock, see the info from: http://forum.xda-developers.com/showthread.php?t=376873
You need to reset before the carrier customizations kick in. If you didn't then that is why you have the Sprint info on your phone.
There are a bunch of threads here about this problem. Let me see if I can find a link to one.
Here is some more info from the wiki:
do NOT boot into the OS after flashing to any of these ROMs.. After screen calibration the carrier customisations will run and alter your EPST settings to that operator's settings.
OOPS! You just let the customisations run but are with a different carrier than the ROM you just flashed to!
Choose A or B
A.follow above EPST instructions in step I to edit back to the settings that you recorded
B.Goto to the Titan Stock Page to restore your device back your carrier's default settings, boot into the OS and permit the cusomisations to run, and then return back here to start over again.

you dont need to reset at all. ugh. follow these steps:
1) flash sprint rom
2) at 'tap screen to set up device' flash your rom of choice
3) install carrier cab
4) soft reset
literally, its that simple. if you need a step by step, i guess here you go:
1) flash sprint rom
no need to enter bootloader unless your installing from SD2) after rom installs, it will automatically reset
3) at 'tap screen to set up device', unplug and plug your phone back in
4)run (assuming you are using DCD) the kitchen or the RUU.
phone will reset after done installing5) calibrate the screen and let customizations run
6) install carrier cab
7) soft reset
done

Hi there,
The 3.42.30 Radio was pulled from a Vogue and was modified to work with there Titan, therefore there is no ship ROM for it. Your best bet is to format an SD card with the FAT32 filesystem and copy the TITAIMG.NBH onto it and load up in bootloader mode. There are thorough instructions in the Titan wiki. Best of luck!
Hate to break it to you all, but if he let customizations run...then he's screwed unless he can get Verizon to issue him a DMU reset. If not, the phone needs to be replaced. End of story.
damn....I had to get a new phone after my first time flashing too...

Are you serious?? oh no
How would you go about asking vzw for a DMU reset? i'm not sure what that is....and would vzw do a phone replacement??? they won't say it was voided?
Thanks all for all your help...i haven't had a chance to reflash anything yet, but gonna give it a go later today and pray it works!

if you call verizon, youre gunna have to make it sound like you know WAY more than they do about the issue. if you google 'DMU reset', im sure youll find some information about this. if you have another phone, switch your service to the other ESN, then switch it back. then call verizon and say that your MIP settings are not receiving a static IP from verizon. tell them you just switched your service back to this phone, and youve had this issue before. Tell them you need the data features removed and re-added to the account, and you need your DMU keys reset.
if you cant switch ESNs to and back, youll have to say you had a serious software issue on your phone, which required a hard reset and now your data connection is taking way longer than normal to connect, and you would like your DMU keys reset.
i recommend researching as much as you can about this before calling. depending on the TSR you get, they could ask you alot of questions. most of the time, if you answer all their questions before they ask them, theyll do what you say
EDIT:
when you do talk to them, before they can tell you any steps, make sure you tell them that you've:
soft reset
hard reset
clear storage
*288 1
*228 2
*22899
those are all the general things theyre gunna tell you to do before they reset anything for you. you just need to make it sound like youve already done everything possible, so the last possible step is resetting your keys for you
VZW has....well, an interesting way of doing things
So, I spoke to a VZW rep tonight after flashing back to a stock VZW ROM and, as expected, not getting a data connection (or able to make calls).
The rep was pretty helpful and knowledgeable. Mind you, i am on AT&T and this is my mom's phone i am helping her with (or at least trying to ). ATT base reps suck and for any minor network thing i would always need to speak to a data support tech (who these days tend to also suck pretty bad as well!) This VZW rep was no dummy and, to my surprise, understood all the things i threw at her. She was overly diligent which gets annoying, retrying lots of the same things, but i understand these people need to be, and she was making progress (bc after flashing the stock ROM my voice calling wasn't working initially either).
When I mentioned doing a DMU reset she explained that she can't do that and in order to have that done she needs to submit a request to her network team. I thought she would have them call me to troubleshoot the problem or something, but that isn't how it works . The network team doesn't speak to customers; she would be calling me back to tell me that the problem should be fixed and they did what they needed to do. I found it odd that they wouldn't need to speak to me to find out if it is working or not....Apparently, she said, they can tell if my phone is working/not working for the data connection.
For now i am kind of impressed with VZW's whole approach on how to solve this kind of thing (although it'd been nice if i coulda spoke NOW to a rep that can actually fix my problem), but i am a bit skeptical that it is actually gonna happen. We'll see what they come back with and hopefully i don't get run around in circles and they can indeed get my data working by resetting the DMU or whatever they need to do.

She could have performed the DMU reset without bringing in the network team. She just didn't know how.
oh. well, for what it's worth, your support reps (even the bad ones apparantly) for the most part seem way better than the ones @ ATT! still not planning on switching any time soon though
Thank you!
I just want to deeply thank everyone that contributed to helping me get my problem fixed. The phone is now up and running and I am most appreciative to all of you that took the time to help me!!!
You really have a great community here!
FWIW, Verizon data tech fixed my problem but when i asked what he did he would not tell me....he basically said he "checked some things out and madde sure everything was set up right" while he had me take out my battery and wait. I asked what specifically he did, for research purposes and he said he couldn't tell me
Lol..he performed a DMU reset. I swear some of those techs are so dumb.
Well, he actually denied that he did a DMU reset cause i asked if that was specifically what he did and he said, no...i just checked some things out...and wouldn't tell me what he did.
i am sure you're right, he did the reset, but they must be instructed not to tell customers what they do...i guess maybe to try to prevent us from telling them what to do?
I flashed the ED05 stock package posted in the dev forum. Everything went well with the flash but when I rebooted, the phone went to VZW for activation and now I have no access to data network. Any ideas how to fix this?

I took a look through the forums and didn't see anyone else lose 3g with this package. Try a *228 and if that doesn't work, flash a different radio (ED04 or EC09) and try to *228 again. Can you make or receive calls/texts?
Worse comes to worse, reflash the ED05 package or flash a different ROM/stock package.
I had that happen once did a few reboots and started working all on its own. It was not with ed05 though.
If you flashed the ED05 with the SamsungPST and you lost data service you have two options (both verified to work)...
1. Login to My Verizon and swap your phone number to some other phone, activate it (*228) and then swap it back to your Fascinate.
2. Call Verizon and tell them you are not getting any data (but voice works ok) and that you would like your keys reset.
I have the same problem, ill try calling verizon tomorrow :s
I've actually tried different things now:
Connected to wifi, if I go into my verizon it says:
Your Mobile Number could not be validated, Please try again later.
When I try calling verizon, it says that my phone is not authorised.
When I dial *228 it unlocks successfully the phone, reboots, and then nothing!!
Help ??
Also I have tried going back to older versions, trying different roms but no data no where
Listen to pentafive. He's posted how to repair. Worked for me.
Update... It looks like you don't even need to *228 the other phone. Just get an ESN/MEID of some other VzW smartphone (that isn't currently activated), swap it on MyVerizon and then swap it back to the Fascinate. Then *228 your Fascinate.
Ok I called them and it worked, thanks everyone .
It was my first verizon phone so I could not try with another one.
Does anyone know why this happened ? To avoid it happening again ?
I am having the same issue. I have voice but no data. I don't have another Verizon smartphone to swap and the tech-support didn't know what "resetting the keys" meant. I am getting a replacement but I'd still like to know how to get this fixed in case it happens again. Thanks.

I recomend using odin instead of samsung pst! If you insist on using pst look up the official vzw stock ed05 thread in the dev section by pentafive. He has directions on how to keep from losing data when using pst.
I had the same proplem. No Data. I call verizon they had me pull batt waite five min replace batt reboot and i got my data working again.
Works
After asking if Tech Support could reset the "keys" for my phone, which they had no idea what that was, I asked if they could activate a different phone on my account then reactivate mine. He told me that would fix the problem if it was a network level problem (which it was.) He ended up resetting the data connection on the line and after a reboot my 3G was back. So, if Tech Support has no idea what "resetting the keys" means have them reset your data because the problem is a network level problem, not a phone level problem.
Also I used Odin and still got the lost data connectivity, so keep that in mind.
A friend of mine has been having a problem with his phone. Its not rooted. This seems to be a known problem as he had this a year ago, he went to the sprint store and the guy flashed something that resolved it. He has data but no signal bars. When he makes a call he gets "call origination attempt failed" error. His phone was stolen, and he just got the replacement and now the problem is back. Tried updating profile/PRL to no avail. Kind of a strange problem so I figure someone would have the answer here. Any ideas?
HW Version is 003
Software 3.15.651.16.710RD

Tell him to try a factory reset it. Then call sprint and have then reset the data connection.

Sorry - I left that out, we tried that as well. No change. Whats weird is the phone worked for a day, then stops, just like when he bought it new. Im guessing this doesnt happen rooted, since im sure 99% of the population on here is rooted. Supposedly its a common problem when the phone isnt rooted.
Rooted or not has no bearing on being able to make calls.
If the phone is fully stock, sprint has tools to see what's going on with it.
Has he tried refreshing his profile? Does he have data?

He has data which is weird. Just cant make calls. Browses the web just fine. He already called sprint who has no idea lol.
Sprint should have him try to clear his config. I can't remember the code off hand, ##786#, or ##72786#. It basically wipes the NAM profile settings associated with his account from the phone. On the next reboot, an OTA activation occurs.
This may be destructive in that one of those does a factory wipe too. I can't remember which.
He should ask for level2/3 support if the first tier person is helpless.

I do remember the last time, we did that and it made no change. The only thing that fixed it is he was told to go to a sprint store because they flash something special and it corrects the issue permanently. Which it did for him, until they sent him a new phone. Very weird issue.
If you've tried all the ideas posted here then I'd recommend just taking the phone into sprint or have them send your friend a new phone.
#Root-Hack_Mod*Always=SG3
As a latest update - Sprint sent him now his 3rd phone and its been working for a little over a week. Guess it was hardware after all.
Yesterday I bought an i717, an unlock code so I can get it working on T-Mobile, and put the newest Cyanogenmod nightly on it.
I noticed that my data speed was stuck on Edge and found out with some searching that this was common problem. I went to this thread and have followed it's instructions but now I've hit a wall and can't figure it out.
I've flashed both the radios that should work but am getting no working results. Can anyone offer me a hand with this? I would greatly appreciate it.
I don't have T-Mobile but suggest try different ROM. Also make sure have most recent twrp

I'll give that a shot, thanks
Thanks for the reply. I tried all that, new TWRP and all kinds of different ROMs but the problem persists. I did notice one thing however, and that was when the phone had the ROM flashed on it, brand new (like just after a factory reset), 4G worked really well. That is up until I turned the wifi on. Turning the wifi back off, and/or restarting, and/or clearing cache and dalvik will not get the 4G connection back. I'm at a loss. Also if I try flashing a different radio I'll have the disappearing APN problem. So for now I'm stuck with EDGE.
What other options could fix this? Could the build prop be making a fuss? I don't really know where to go.
It sounds like your sim isn't a 4g provisioned sim. The APN would stick if the sim was appropriate.

This is "The Answer Post"
I got it! It was in the mobile network options. Since this is an ATT phone with an ATT radio I had to think a little differently, since I'm used to T-Mobile settings. The "Data Roaming" and "National Data Roaming" check boxes were unchecked. Again, being an ATT radio I guessed that these needed to be on. Once doing that I went down to network operators to manually select "T-Mobile" as my network. Once I did, voila! 4G connectivity now works like a charm.
Just wanted to let the internet know, in case someone else needs this.
Good save!
Short version... I installed CM12 official. From that point forward I have been plagued with a persistent network issue. Obviously I know this is my go to group of peeps. So here I am.
As pictured below I have many more options in preferred network type then I probably should have. Also I have more APNs then I remember previously having. I'm not even sure the APNs are setup correctly. I just need to know how to revert to how it was before the CM12 install. I have sense changed the radio twice to attempt a fix and have also installed two other ROMs. One of which worked fine before the aforementioned issue. If I select from below LTE / WCDMA, I get data with no cellular service. If I select CDMA + LTE/EvDo I get cellular service with only 3G data. Please someone have an answer for this one.
Bump. I have done plenty of searching. What I did see was there are three files that I maybe missing. They are referred to in another very similar posting on how to unbrick a bad flash from N7100. That being said. Those files mentioned are not available. So I'm hoping someone can shed some light on this.
I have this exact same issue except at times I have no data whatsoever where I did before installing CM 12. Came from Alliance rom on my Note 2. Any help would be appreciated. It's very frustrating.

At the very moment I have most functionality back short of having to reselect my APN at each restart. I don't know specifically what got Mme to this point. Although I used a combination of NV Reader/Writer, Samsung Phone Info+, reinstalling a EFS directory using ODIN, IMEI changer, and a new sim. I also forced the cellular band to auto and set the PNT to LTE/CDMA. Although as I said Im not sure what helped most and even so its not all fixed 100%. Let me know if you want more details how I got to this point.

Really messed up before and ended up with almost(if not the) the same problem.
I contacted http://www.mobiletechvideos.com/samsung-galaxy-note-2/
And they got me back up and running within minutes.
Just something to check out if you still find youre having issues after you finish trying more.
Take care
I hope you don't mind. I read all your other posting to make sure you were not an advertiser. Awsome feedback BTW. I'm surely going to look into what they have to offer. Sense I have only managed to get so far on my own. I would like to find out they are a company who has the ability to bring it back to out of the box condition. Then I will take the proper steps to ensure I don't make this mistake twice.
