I just started having this issue, i can't connect to any data at all, i have tried battery pulls, using restart connection, running different roms, using restores where everything was working, doing a full wipe and then installing a new rom, but still no luck. Should i try just a factory restore? i also read that taking out the battery, then take out the sim card, booting the phone up with out the sim card in, getting errors and then shut it off and then put the sim card back in works, but im not sure which of those to try, any advice?
when that happened to me i did a factory reset and it worked afterward
Check around first, see if Verizon is having problems in your area. I know recently places have been popping up with sporadic outages.

But isn't installing a rom and wiping the data and cache the same as a factory restore?
I had this happen to me earlier this week. When I called Verizon support they told me that towers were down in my area, they told me the same when I called back the next day. Meanwhile, others who own the TB seemed to be having no issues. Finally I took my phone into a Verizon store and they are shipping me a replacement phone. They would not swap my phone in the store since I was a whopping 4 days beyond the 14 day return window...but, I digress.
The one workaround that I found in the meantime is to switch your modem settings. Dial ##778, select Edit Mode, enter 000000 as the password and select Modem Settings. Select Rev. A and choose Enable. Press your menu button and select Commit Changes. Your phone will reboot and you can use the LTE On/Off App (or just dial *#*#4636#*#* and choose Phone information) and switch the radio to CDMA Auto (PRL). That enabled me to have 3G data, though it seems extremely slow relative to 3G on my OG Droid. But, in a pinch it seems to work.
One additional bit of advice, in case you are running a custom ROM. I was running Virus ROM and ##778 would crash whenever I tried to run it. In order to swap the modem settings, I had to flash back to stock and make the updates, then flash back to Virus. I don't know if this is specific to Virus, but just an FYI.
Just tried on das bamf and worked fine (##778) must just be virus.

Thanks, that got my 3G working, will i still have 4G with it on that setting? or do i need to switch it back to use 4G or do i get the Lte on/off app?
*#*#4636#*#* and tap on phone information and go to the box that says "CDMA+LTE" THATS default 3g and 4g and for only. 3g is auto prl

You won't get 4G on that setting, it turns the 4G radio off entirely. You would need to switch back to the CDMA + LTE/EvDo auto or LTE mode settings to get 4G. Ultimately, my issue ended up being a defective phone. You can try to wait it out and see if you get 4G back later, but you may just have a faulty device.
If that is the case, just remember to follow the instructions that jcase posted in the development forum to get your phone back to stock with s-on before taking it into a Verizon store. If you bring a rooted device in, I suspect they aren't going to honor any sort of warranty.
My phone had this problem too... turns out when I went into a 4g area the mobile network box got unchecked in the wireless & network settings.
I use the "verify with multiple devices method". I am tired of the standard VZW "towers are down in your area" bs answer.
If another tb, xoom, and bb have service and my tb doesn't, that tells me something is wrong.
I have a feeling that there is something seriously wrong with the network (implementation or backend hardware) that is causing this with 4G devices. Either that or the tb is to blame entirely for Verizon's 4G issues...... /rantoff..... LOL

Was having issues earlier today with 4G. The connection and signal were good, but no data would download. The white up arrow would light up, but the down arrow never would. It was like that for about 4 hours. It's working great now and speeds are disgustingly fast.. maybe VZ doing some maintenance?
EDIT: THis is in San Diego.

Factory Reset from bootloader worked for me. I had the exact same problem. Tried everything that was suggested, but no data still. Only enabling Rev. A worked.
Thanks for the help, the problem I'm having now is I got 3g but I can't get 4G back, I have tried to switch my settings back to get 4G using LTE on/off and by dialing the number, and I have had no luck, in those menus it tells me service type LTE but it is disconnected, and I get no data or 4G symbol in the status bar, so I'm confused if I maybe messed up a setting or what, so should I just try a factory restore via the bootloader and see if that works? Any other suggestions ?

I would try the factory reset from bootloader, but I was on the stock ROM when I did it. So I don't know if that would matter or not.

Just to reiterate, my 4G never came back. The phone was just broken. It sounds suspiciously like you are having the same issue. Maybe there is a manufacturing defect that makes this issue more prevalent with this phone right now? If you are in the 14 day return period, set your modem and radio settings back and get into the store ASAP to swap the phone out. Otherwise, call customer service and have them replace the phone. They will overnight you a new phone if you complain enough.
Ok I was looking through my modem settings after dialing ##778 and I had changed the rev a. Setting to enable, that got my 3g working, but what is eHRPD is that would I should have it on too have 3g/4g? But everytime I have tried setting it to that I get no data so is that the setting that is messed up?

I have CM7 installed on my G2X and the radio turns off on its own -- it reports no signal. In order to get the radio working again, the only thing I can do is reboot my phone.
Also, to even get the radio working, I had to install "APNs Backup" from the market.
I am running android 2.3.4 on CM 7.1.0-RC1-G2x
My baseband version is:

Has anyone else had this problem? Can anyone confirm whether I have the p990 baseband instead of the p999 baseband by accident? (as reported here http://forum.xda-developers.com/showthread.php?t=1037098)
Lastly, can anyone help me flash the BIN_LGP999AT-01-V21e-310-260-JUL-15-2011+0 baseband from here:

Specifically, I am not sure which of the two BIN files to flash, and what the correct nvflash command is (which partition does it go to?)... I can't use smartflash or any windows tools...

What radio are you talking about?
APN is a known issue for CM7 based roms.
The baseband you have right now is a g2x baseband, though, it was the one when it came out with froyo.
Why you have to partition or repair partition on your phone if it has mo issues with partition?

CM7 or any 2.3.4/2.3.5 ROM for the G2x is known to have that issue. They are working on it currently. The APN's Backup App works for me tthough.

FatalityBoyZahy -- do you do anything special with it? It allows me to actually get reception (I can't without it) but my radio will still drop and force a restart. Do you have any special settings on it? When the radio drops the tool no longer has the list of APNs and I have to "restore" to get them back.
I was using the experimental (RC1) ROM so I just flashed the 155 nightly. So far a few of my network issues are solved. I'll update if it's completely solved tomorrow.

I could send you a copy of my APN's if you'd like. You'd just need to put them on the SD Card, and restore them through the app. Shoot me a PM.
I have the same issue. My phone randomly looses connection even in good signal areas. Only way to get back on the network is to toggle flight mode or reboot.
This is a known issue on all Android phones that has persisted throughout all Android versions. Google has worked on the problem and it has gotten better, but they haven't been able to exterminate the bug yet. This phenomena occurs when the 3G signal is weak and the phone switches back and forth from 3G and Edge frequently. Eventually the phone just shuts down the radio due to it switching too much. This is the Android OS commanding the radio to shut off. It is not a hardware issue at all. I have had this issue on every Android phone I have owned. Ironically, the only phone I haven't seen the issue with yet is my G2X running stock GB. The best way to alleviate the issue is to install "Network" from the Market and set the phone to 3G only. If your custom rom has a 3G only option just set it there. There is also an app called "3G only" that accomplishes the same thing. Since you are locking in 3G the phone won't switch frequently and the radio will stay on. You can do the same thing by setting it to 2G only, but who would want to do that.
Network: https://market.android.com/details?id=de.mangelow.network&feature=search_result
3G Only: https://market.android.com/details?id=com.mobnetic.only3G&feature=search_result
I think my issue is more severe than it is for you guys. Fatality - when my radio goes out, nothing but a reboot turns it back on. Not airplane mode, not toggling data on off, not changing apns. In fact, when the radio turns off any menu pertaining to the radio freezes and asks if I'd like to force quit it.
Also, I doubt that this is the long term Android bug. I've owned probably 10 or 15 android devices and I have seldom had to restart the phone because of this. For my g2x, I have to reboot literally 15 times a day.
I had two more leads I am trying.
One was that I have a 5 year old T-Mobile SIM in my g2x and I read somewhere that an old SIM could be a problem. No such luck, the radio has already turned off with a brand new SIM.
My second lead is my baseband. I have a March 7 baseband, but the two basebands online for g2x are March 17 and a later one. So, perhaps I do have the wrong baseband?
Thanks,
Ben

Oops I forgot to respond about jboxers suggestion to limit to 3g. It didn't work, either.
The network app didn't seem to have a 3g only mode, the 3g only app didn't limit my phone to 3g (it was still 4g) it only turned data on/off and also the radio still turned off, so I tried using the phone's 2g only mode and that immediately killed the radio.

3G and 4G on HSPA are inseperable. '3G only' will give you '4G' also.

As another poster already said on TMO 3G and 4G are the same thing. In fact, TMO doesn't have real 4G. HSDPA+ is fast but it is not true 4G. In some countries it is referred to as 3.5G and here in Thailand they are calling it 3.9G.
The network app does work. You scroll down and selected "WCDMA" only. That is 3G/4G. That will lock the radio into 3G and 4G only. The 3G only app will lock it into 3G and 4G only. There is no way to say 4G only, because it is not real 4G. If TMO had LTE that would be a different story.
Ah, that's good to know that 3g=4g on t-mobile. How come sometimes my phone says 4g and sometimes 3g?
Anyway, I wish that was the issue
Does anyone else have any ideas of what it might be?
What baseband version do you guys have on your G2x? Does anyone else have the same baseband version as I do?

HSDPA=3G, HSDPA+=TMO Pseudo 4G. HSDPA+ is an enchanced version of HSDPA with faster speeds but not true 4G. Most devices display an "H" but TMO had it programmed to "4G" to pretend they offer 4G service. Both are versions of WCDMA, which is what GSM 3G is.
I found this thread that has another kernel that supposedly fixes the APN. I haven't had my kernel drop yet, but it's only been 10 minutes Here's a link to the kernel:

and everything worked fine (don't forget to clear dalvik cache on reboot).
To run the script he linked to, download ScriptManager from the app store.
It fixed my radio! Though it did kill wifi.

Try toggling airplane mode. Might help to remove your SIM card & ensure the contacts are clean then reseat it.

I changed the url of my provider from "live.vodafone.com" to "live .vodafone.com" (watch the space between live and .vodafone) and all of a sudden E/G/H appeared in the status bar.
Still, double check the APN settings, make sure everything is entered in right (proxy, username, authentication type, etc). Were you able to send pictures still? You need to make sure it's not a hardware problem.

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.
With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.
Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?
When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days
Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.
I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.
Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"
For some reason I cannot get LTE to work at all on CM10. I've done everything and it still wont work at all. I tried reverting back to stock rom, and when I did, LTE worked. So I thought if I went back to CM10 from stock it would resolve the issue, but it did not. I've checked my APNs and I cannot change the preferred network mode and i tried *#*#info#*#* and i can't change anything there to anything that has LTE on it. I'm not sure if it's just a problem with the ROM or what, but I've done plenty of researched, searched all the forums, and can't find anything that will fix.
Additional information:
Im in ATT
I've tried all the radios
and I AM in an LTE area.

For some reason I cannot get LTE to work at all on CM10. I've done everything and it still wont work at all. I tried reverting back to stock rom, and when I did, LTE worked. So I thought if I went back to CM10 from stock it would resolve the issue, but it did not. I've checked my APNs and I cannot change the preferred network mode and i tried *#*#info#*#* and i can't change anything there to anything that has LTE on it. I'm not sure if it's just a problem with the ROM or what, but I've done plenty of researched, searched all the forums, and can't find anything that will fix.
Additional information:
Im in ATT
I've tried all the radios
and I AM in an LTE area.

Just making sure, but you know the LTE icon doesn't exist in cm10 , right? LTE is indicated by the 4g icon

Ok, try different apn. Which cm10 are you trying to use?
Does the problem happen on other ROMs? I'm not saying to use a different ROM, just saying that if it doesn't happen on, say, AOKP or Orthus (both CM-based), it's probably an issue with how CM10 is configured on your phone.
If you go into network operators (settings -network)and select att it will allow to change modes.

Haha yeah most of the time this setting is overlooked and this option enables you to turn off LTE if you want (which you don't have to have a RAT unlocked modem as presumed) and if you go to *#*#4636#*#* on your dialer you can have it set to LTE only as well.

I actually have another problem now, after a reboot, it doesn't show any options for me to choose under available networks?
it came back after a few tries but then went away again, it's not consistently there to choose.
Does it show a searching animation?

I have the exact same issues. I've done everything on this post plus done all the research as well. For my problem whenever I enter an LTE area my data service completely drops for about 5 seconds and then when it connects it only shows HSPA+. I have never been able to pick up LTE. When I was on CM9.1 I had no issues at all. LTE connected with no issues. So is this a CM10 issue or a phone issue?
try this, might help, might not, make a backup, if you have more than one apn, remove all apn's except your lte apn(ATT Pta, for rogers :ltemobile), restart phone
edit: of course make sure it was set to the lte apn in the first place, if it was and still have probs, do above procedure if you have more than one apn

For some reason my APN was not set to the lte one (ATT Pta). I changed it to that. Hopefully that fixes my problem. Thanks for the help!
I have a slightly different problem. I am running the latest cm10 nightly and notice that any time I get lucky and go into a 4g coverage area I can only make phone calls. No data transfers at all. I have my APN set to ATT LTE pta which I assumed is the right selection. Im normally in a A3g(HSPA)~700-17 coverage area. Is this the wrong APN to use?

The APN change worked for me. This is the proof

Do you automatically switch back and fort from 3 to 4g with that APN setting when you move around without losing data capability?

Yup. I have HSPA/HSPA+ around my house but close to work I have LTE. No problem with switching or losing data connection when I go from HSPA to LTE. Just double check your APN settings. There might be a typo or some missing field. Or you can create a new APN for lte and use that as your default.

@26.2man, you've gotta have att provision you for lte at the store or whatever if you haven't done so already. Then it should work.
