3G connection not working

I'm running a rooted GB on EI22. Everything is working including 4G and wifi but 3G will not connect. I've reloaded my profile and reset my PRL via wifi. Put it in Airplane mode the turned it off. The 3G shows in the banner but won't connect. Any ideas?

there's your problem. if 4g connects.. use 4g and update your prl and profile and reboot your phone, then try it. it may be slightly slow at first, but after about 30secs, should really start kicking in.

I am able to run HD Dolphin and other applications on 4G however the moment I attempt to update my profile or PRL it drops the connection and errors out.

odin back to ec05 and then start the process over again. except when you do this, odin twice. and then try it. you may have to flash a different modem, like shadowkernel.

A modem and kernel are two entirely different things. Shadowkernel is not a modem.

[Q] return epic to factory release condition

My epic has an epic problem, i had dropped it just a few days ago and its touch display stopped working. I cant see anything on the screen. I need to get it back to 2.3.4 without having root or clockwork mod on it so i can get it repaired. is there any solution?

You need odin, the ec05 tar, and victory pit. Search qbking77 on youtube. All you'll need to do is power off the phone, and then when you connect the phone to your computer, you'll hold down the number 1 on keyboard, and the power button to get into download mode. Its easy.

I just re read your post. If you can't see anything on the display, than your service provider won't have a clue that your phone is rooted.

Don't chance it with this, at least, not in my opinion. I would go the Odin route as suggested above, to make sure you cover all your bases. And get all that stuff off the SD card too, like the clockworkmod folder and anything else that would imply root was there at some point in time.

Just odin back to ec05, and after ur done, just take ur sd card out before taking ur phone to sprint. If they ask for it, just tell them u miss placed it somewhere at home.

[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.

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.

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

[Q] Issues - UGH

I'm having some issues. I am on Incredible HD RLS 2, I haven't been able to get on WiFi and this isn't the only ROM where WiFi isn't working. It will just never connect. Well, I tried to install ICS Official global CM9 upon initial boot it said it couldn't read my SIM. I powered down pulled the SIM put it back in and put the phone back together and then I couldn't get any service. No matter what I did I have no service.
Yes I followed all the instructions, wiped everything, flashed the proper gapps and the kernel.
Since that didn't work I went back to my nand and still no service. Anyone have any suggestions?? Please help

On global cm9 rum through setup and change network mode to cdma/evdo becuz it defaults to gsm
I'm so fresh you can suck my nits...

Will give it a shot, thanks.

Awesome, got service back, but WiFi is still not working. It just forever searches and never connects to a network. Anyone have any ideas?

This happens to me sometimes and restarting my router usually clears it up, not sure if you have tried that, just throwing it out there.

I can't reset the router, I'm on a college campus. I have the latest firmware and radios,switched out rom after Rom and still WiFi doesn't work. Any other suggestions?

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.

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

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)

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).
