[SOLVED]Can't get 4g or 3g. Only E.

I fixed it by flashing a new ROM and wiping all the data!

Someone please help! I don't know what to do!

Nevermind, I think I fixed it!

I fixed it by changing the band to GSM Preferred/GSM ALL but now I only get E. Any way I can get back 4g?

Change it back to automatic or Odin kl1 modem from rootzwiki team kang post.

I changed it to auto, and i'm getting signal. Time to check if 4g. Thanks.
EDIT: It shows signal, but Im not getting any. Can't send text or browse web. Time to odin modem.

I flashed it, and I went to settings and looked at the network mode: It was GSM only. I changed it to auto mode. It seems to still get and send texts, and I looked at band selection with the dialer code, and there wasn't a star besides anything. I think it might've worked, but I still only get e.

By flashed I mean odined. Lol

I tried changing it to automatic in the band selection menu, and it showed signal, but texts didn't send.

Also, if it means anything, I can't change it to wcdma only in settings.

I had same issue and this is how I fixed it.
disable data connection and switch your phone off, remove the back cover and remove sim card completely. Then re-insert sim card and turn your phone back on and it should ask you to re-enable data connection once it boots up.
let me know if this helps

I did this, but it didn't ask me to turn it back on, so I turned it on manually, and still only E.

Other phones receive 3G? Perhaps T-Mobile is servicing your area? This has happened to me but I had no control over it.

Did you by any chance flash a rom port?
Sent from my SGH-T989 using XDA App

Weird. My issue was that I was testing a few of the skyrocket modems. After using Odin to get kl1 it worked again. Yeah i would sugeest resetting apn in wireless settings .
Sent from my SGH-T989 using XDA App

Here's what I did that messed with my 3G
I flashed skyrocket roms.
So what I did was wipe everything. Go to mounts and storage and format system. Then flash Juggernaut or any other rom you desire. Then you're done

Sprint automatic connection, under mobile network/auto connect uncheck it.

Ok thanks man. Does you phone go into roaming a lot? Mine does, I had the OG Evo and it was never a problem but this new phone seems like it's always in roaming. I have already done a PRL update multiple times.

I turned my roaming off, you should try and changing your modem.

Certain text not going through

Sometimes I get a notification saying "target server failed" when I send texts and the text doesn't go through. How do I fix that.

Need a lil more information...like rom and messaging app? Possibility there is an overloaded network in your area, cuz that's definitely not rom related per say.

Well try it on go sms and see what happens. if its still not going through it'd be a network issue of loss of signal.

Problems with roaming...

I had roam control on my phone not too long ago & it worked perfect. Nothing it didn't do that I wanted it to..
Well I recently put it back on my phone & it's still working , but now, whenever I am in Roam Only mode.. Nobody can call my.phone.. When they do, it just goes straight.to my.voicemail.
I used to be able to receive calls just fine, whether I was roaming or not.
Anyone have any ideas of why it may be doing this?? Would appreciate any input.. Thanks guys!!

What is your rom, kernel, modem, and prl?

I took a screenshot of my about phone section and attached it. Is that what you were asking for? I don't know how to check my prl. If you can tell me how, I would appreciate it..

At the top of that page where you took the screenshot should be a Status or Phone Status option... tap that and scroll down to see the PRL.

For example my prl is 60690 and it roams just fine.

Mine says, PRL 21092

& I have come to find out that, if someone calls me it goes straight to voicemail & it's not just when I'm using roam control app.. It's anytime I roam at all...
How can I fix this??

Are they doing work in the area? This happened to me during NV upgrades.

Don't think so. I have horrible service where I live. I'm on sprint, but for some reason I get no signal here usually. That's why I use my roaming sometimes. But I've used the roam control app before & would get calls just fine when roaming. Then I had to reset my.phone and reinstall the app, & now I can't get calls while roaming, at all.

No data connection after flashing a new ROM? Look here for fix.

I experienced the problem of no data connection after flashing a new rom on my Optimus G. The phone needs to be reprogrammed, updating your PRL and Profile will NOT help. You must dial ##72786# this will start the handsfree activation and your phone will reboot a few times. It may take a few seconds in between steps of the activation and it will seem like nothing is happening. Just be patient and wait for everything to complete. When it is finished your phone's data connection will be working properly.

Sent from my LG-LS970 using xda app-developers app

Some history,
I've been running Imperium and stockishv1 and v2 for a few days. I've made a couple backups along the way. About an hour ago I lost data. The phone works and makes calls, but my data is dead.
I've tried update profile and prl, and all I get is" Network error" I've tried this many times throughout all these steps.
I've restored backups, pre-Imperium and Stockishv1 with the same results.
I tried the procedure in this thread and still nothing.
Anybody have any other ideas? Would LGNPST restore the phones modem?

You guys need to read this. I am going to open an LGOG Issues thread but need to grab some food first.

I did, and responded in your ROM thread. Thanks
edit: Now all of a sudden data is working. BTW when my data wasn't working it still showed a flashing 3G. Sometimes. Both arrows on and off
edit 2: Also when data wasn't working, It kept wanting to roam.

saw the same thing on stock as well

More than likely your area no? Sprints been working on towers

Related:
I killed the connection optimizer while I was at work because I can't use work's wifi and listen to my icecast station I setup.
This killed my data connection and immediately put my phone into roaming. I rebooted like three times and finally my data came back (i also updated the PRL and the Profile, not sure which fixed it but something did)
From the things you guys speak of, I would guess the same issue is at hand.
ALSO: Stock rooted rom (non-deodex pure stock with bloatware frozen with titanium)

No Data Connection
I'm pretty new here and I"m not sure where else to post this,
but I"m having a similar problem.
I am running CloudyG3 rom on Verizon LGG2 and after flash I have no data connection at all.
If anyone could help me or direct to somewhere where I can get help, I'd appreciate it. Thanks

Try the G2 thread, I'm sure if you post in the exact same section over there you might have better results. General answer is that it is probably APN settings. Find an app, enter them, set it, and reboot (might not need to reboot).
