I am new to root and ROMs so perhaps I overlooked a setting.
I just rooted my phone and flashed CM 10.2 a few days ago and I cannot get 4G anymore. I can only get 3G. I have tried a few fixes like dialing *#*#4636#*#* and adjusting the APN settings but nothing worked. I have the LTE button ON and I am wondering if I am still getting 4G because I have LTE on and it's just showing 3G. But I don't think that's the case.
Any help or tips would be greatly appreciated!

reflash stock rom. make sure you have 4g. flash the vram3c radio then flash cm10.2 rom. you should have no problems with 4g after that.
I will try that. Thanks!

I tried flashing the radio and CM again and sometimes 4G comes up for a few minutes and goes back to 1X. This happens where I have gotten 4G before. Maybe the radio isn't as strong?

My personal experience, living in a fringe signal area, is that AOSP roms just don't have as strong a signal as TW roms (it presumably has to do with how the RIL had to be hacked/reverse-engineered to work for AOSP). I would prefer running AOSP, but unfortunately in my experience on my S3 and Note2, where I am located on the fringe of full 4G coverage areas, I have the same issues as you: on TW, full, fast, 4G; on AOSP, very obviously slow 3G or 1X.
Edit to say I've only tried 4.2.2 ROMs, haven't tried the 4.3 ones yet, so if I'm handing out wrong/outdated info, I'd love to be corrected.
I am now running a stock 4.1.2 ROM and still cannot get 4G. I now for some reason can't even dial *#*#4636#*#*. When I try it just says "Welcome to Verizon Wireless, this call cannot be completed as dialed." Anyway to get that number to work so I can check my networks again?

Try going into settings and factory reset phone now. If that doesnt work, reboot into stock recovery and factory reset from there and reboot. That seems to restore signal for those of us that got stuck in roaming mode from the Carbon thread. Might help your problem too
So I decided to re-flash CyanogenMod 10.1, adjusted the APN settings again, and I have 2 bars of 4G right now. Usually 4G will flash a couple times and change to 3G, but it is staying 4G, so hopefully it stays that way!
Well it stayed 4G for a bit until I turned WiFi on. The moment I turned it on, my 4G went to 3G. I turned WiFi off and I still have 3G. Anyone know what would cause this?
EDIT: My network type shows eHRPD with 3G, where as when I had 4G (before I turned my WiFi on) it showed LTE. If this helps any.

Where do you live, i know the mid Circle drive all the way over across platted to the airport are just dead zones. I lived on Verde drive and rarely had good signal, then when i moved up circle behind the bowling alley i never had a good signal. Just something about the antennae in that area. T-mo is a complete bust in that area. But i'm sure you probably all the way over on the Nevada side completely making what i said irrelevant.

Do a search on towers in your areas. If I remember correctly the closest tower to you in right by the interstate by the new (now not so new) MCD's in Security. That tower had alot of problems in the area past the Olympics complex all the way back to Peterson because of the radio towers for the Jets. I have been gone for almost 3 yrs so don't take what i say as truth tho. Just how it was when i was there.

I've had that problem before. .I used a mod like this.
This mod is from DroidXcon, Try this and hopefully it will work. (make a backup of your buld.prop first)
Instructions:
1)Go to market install BuildProp Editor
2)Once installed find and open Build Prop Editor
3)Hit the menu button and select Edit
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
9)Power down and change to your desired SIM card if you hadn't already done so
10)Power back on and go to Settings>More Settings>Mobile Networks> Access Point Names (if done properly you should see the APN data you entered for your respective carrier).
11)Select the respective APN listing and then you should have working data

I tried this but having the same problem, so I decided to save the APN each time I edited an item, and every time I would change the MNC and save, it would not be on my APN list, and it would be blank again.
Bump... also having this issue. Trying CM 10.2 for the first time since August. It had Bluetooth issues back then, so I've been running Bean's ROM until yesterday. Can't get 4G serivce in what is absolutely a saturated 4G area...
Was able to fix the issue by wiping the phone completely (including internal storage!), installing Bean's ROM, doing a factory reset, then coming back.
FWIW I always wipe internal storage when going back and forth between 4.1 and 4.2+ roms, seems to alleviate any SD card issues that can arise from the changes to filesystem in 4.2.

Having intermittent problems with my mobile internet and was wondering if it was the phone, other users or just plain crap signal.
Have anything between 2 to 5 bars here, hsdpa symbol on constantly but for some reason it occasionally gets stuck on the upload arrow and then the data connection freezes and wont come back on til I toggle mobile network or airplane mode.
Phone is running modaco 2.2c and latest radio on T-Mobile UK.
Hi. Been lurking around since I got my Hero, and thought it was about time I signed up to this excellent forum.
I was having exactly the same problem. Didn't know whether it was a problem with the Hero or the network/signal. I noticed that the APN settings on my Hero were different to the t-mobile site. I read around a bit and tried a few combinations of settings and eventually got it sussed.
Go to t-mobile.co.uk
Hover over "Help & Support" at the top and click "Phone Support". Click "Make the most of your mobile" and choose the G2.
Click on "Set up the phone for internet surfing" and enter the details shown there exactly in a new APN on your Hero.
The only change to those details is the password should be "pass".
This is the only APN setting i have tried that doesn't give me the original problem. Now I can browse without the 3g signal getting "stuck"
I'm using an unlocked Hero - completely stock btw.
Hope this helps. Let me know how you get on.
I've been having this very problem. That's good information, I'll give it a try.
Seems to work well. Here's the link.
thanks for pointing me there.
k i altered my settings, will test it thru day see if it improves.
Ooh, seems to be working so far. Seems I owe you a beer. Lol.
After a day or two using this 'fix' I find it the drop still happens sometimes but not as often.

Personally, I had this issue the first time i flashed test4. No data without wifi, and voice bars were very laggy. I switched back to my stock rom for a day, and when i returned to play with it that night (reflash from .zip, not restore from backup), no more problems. The initial transition to 4g from 3g seems to take a bit longer than on the stock rom, but once it is up, everything is smooth. Not constructive, I know, but it is a data point.
ok thanks. but which is the link to test 4. i have a feeling i installed the wrong one. can u send me link if u can? thanks
Check the device thread on cm7 pre alpha links are at end. You want the one with a three which is actually the fourth one.
Here is how to get signal.
1. Goto network settings, scroll down to network type, select the cdma/edvo option.
2. Wait until green 3g. If it doesn't pop up repeate step 1
3. Once green, change setting to cdma+lte/auto and hit your screen off button. Don't touch phone for 5 minutes.
I'm not sure turning screen of makes a difference but this is how I've repeatedly done it.
I have found that if you loose 4g you can loose all data. Just repeate above. It seems to work for about 10 hours then a reboot is required.

tonyagee is correct. This worked for me when I originally had your issue.
thanks guys but this doesnt work for me. ive tried it with stock and leaked radio.
I too have CM7 and have issues with data/3g. I'm not in a 4g area so I can't speak for LTE. What I noticed is that if I'm connected to a wifi-network and move out of range. My phone has a hard time getting into 3g and vice versa. If I go from 3g to wifi. Same thing. It appears that this is a bug but I'd like to find the buglist so I can confirm. I have, however, been able to get around this issue by rebooting. A good indicator of data transfer is when the wifi icon or 3g icon is green and in the case of a 3g icon, the arrows are flashing. If they are white, you are connected, but you aren't getting any data.
Not sure if this answers your question but I would try the wififix that Imoseyon made (link is in the CM thread somewhere). I enabled 3g, then rebooted into recovery and flashed the wififix file. Once the phone rebooted, I was able to move between 3g and wifi without issue as long as 3g was enabled first.

I am in a heavy VZW 3G area and all day today I have only gotten 1X on my phone. A couple times I had 3G for a few seconds but then it would either go back to 1X or just show the signal bars with no notification of what network you are connected to (what the signal icon looks like when you are connected to wifi)
I did a full wipe and reinstall of my rom and even reinstalled the radio again in bootloader (the latest 7/8/11 OTA radio) and still only get 1X at best.........
I'm hoping its just the area here and not my phone...........???
Please use search.
Its probly fine. Can you go online and browse alright? If so, its fine. 1x is for voice, so its always going to be "on" persay...

check your radio toggle settings ie - where
you toggle 3g/4g radio on/off.
- check and see if your radio is set to:
"CDMA auto (PRL)"
i had the exact same issue and come to find
out I had mine set to "CDMA only"
Also make sure your battery door is completely on
wow so......last night and today
I'm experiencing the same problem now too!
I no longer see 3g at all. just the bars
i have:
- flashed to different backup
- pulled battery & sim
- checked battery installed correctly
- checked radio was on cdma prl
and still nothing
dial ##778# from your phone... Go to edit mode, go to "Modem" and change modem from whatever it is one to "RevA" and then reboot. That should fix the issue.

I just switched from a rooted One XL that was running Scott's CleanRom 4.5DE to a new One X+ that I've unlocked and rooted.
One of the features I miss the most is the ability to force the phone into 3G for most of my use with the ability to turn on 4G when I am watching video or something that requires more data.
Is there an app that works well at switching back and forth easily? I did a search in the play store and there are a couple in there but they seemed to be geared for phones that are CDMA/LTE rather than H+/LTE.
Thanks!!!

I'm using Widgetsoid...add a widget to the screen and choose the "4G" plugin. That will bring you to the radio menu where you can select GSM/WCDMA only instead of GSM/WCDMA/LTE.

You may need to toggle the radio off/on after you change between 3G/4G to force it after you make a change.

You just have to make a apn for 4g network then you just go into apn and select the 4g apn or the lte apn
As far as 3g I donno I can just change mine from lte o hspa hspda or lte but I'm sure there's a 3 g only apn I just don't know it

Seems no matter which I pick it just resets to the standard option.
If I turn the radio off first I can set whatever I want, but, upon turning back one I still get 'LTE' even if it isn't the selected network type.
EDIT: I see I have the same problem as 'moregadget' in that no matter what I do it just seems to go back to its default settings. It must be some BS AT&T did to prevent us from opting out of the battery sucking LTE connection.
I am on an unlocked bootloader & rooted on the Elegancia 3.1.0 AT&T rom.

So I was loading the Team Venom ViperXL+ 1.2.0 ROM yesterday and had a moment where I felt like an idiot. As I was selecting the items on the ROM that I wanted to load I ran across the area where I select what 3G/4G icons I want and I suddenly realized something I haven't seen on the One X+ forum but was prevalent on the original One X.
When you have the AT&T 4G icons in use you can't manually select the network however when you load a ROM that allows you to use the typical H+/3G icons that I believe are on the international version you can.

I really need some assistance ASAP on this one, folks. My phone/text is not working at all ever since I did the following stupidly today.
I tried to see if there was an option to get 2G/3G/4G working on the VS985 on 7.0. Guess I shouldn't have been so curious.
The only real steps I took to see was going to: Settings>Fulmics Tweaks>Advanced>Hidden Menu>Modem Protocol>Changed to Automatic..........now I have NO talk/text. Only 4G LTE data. Does anyone know what I'm referring to here? How do I get back to the original settings which worked fine!?
There must be a way out of this mess.
EDIT: there is! seemingly random combo led me to a solution.
Under the phone settings for mobile network - network mode: select CDMA+LTE/EVDO, and under the access point names: use VZWINTERNET. Make sure both of those are also the same in the hidden menu as well as selecting AUTO under Modem Protocol. That seemed to fix it for me.
Mods can close this one up.

So far, so good. I haven't been to any areas with 3G coverage, but I hope to have that working as well now. I'm traveling halfway around the US this week, so it should make for a good test. Also installed Greenify - does voodoo magic for the battery life.

Thanks! If the combo above doesn't work, you can also try auto under the hidden menu frequency, and auto (or global) in the phone APN settings if LTE/CDMA don't give you a good signal or only give you data but not voice. For some reason the phone APN settings may look different depending on what you have previously selected or when you reboot. The access point should always be VZWINTERNET and you should not change any of those values in either the hidden menu or the phone network menu.
Once you get it figured out, you should not have any further issues or need to tweak these values unless traveling internationally. If that is the case, check the LTE bands carefully 1st and adjust frequency 2nd.
I'd be extremely cautious about changing any of these values. If you make any mistakes, recovering can be a slow process as these are system level changes that will impact the phone - no matter what version of android, rom or nandroid backups you had previously - cannot override these changes. Also, screenshots won't help because the changes in the hidden menu aren't reflected in the UI.
