Help - Cm7 Update - G2x - No APN connection....

Hey Everyone,
Whenever I update to any version of cm7 and flash a new kernel with it I lose APN connectivity... I can't manually connect either. No 2g/4g nothing. Wifi is fine. I've tried multiple versions of cm7, etc. I don't have the same issue with Eagle 1.0.4 and/or Team Whiskey, flashing back to stock, etc. but anytime I try to check out CM7 I can't get it going! I figure it's something simple but does anyone have any ideas so I can try to get some OC going! Lol...
Thanks Everyone...

It's already been reported. A mod will move it shortly. Next time post in the Q&A section. This area is for Development only...hence the name.

Try it without the kernel.
- BFL

I've been recently having the same problem.

Not a problem, this was a question concerning development and more or less the roms I'm downloading from this section hence I posted it here... won't happen again.
As for flashing w/out the kernel, I thought you needed another kernel to run cm7 with? I'm trying to overclock basically which I can't do on the stock kernel either.... so I'm not really sure what to do but I'll see if I can flash back to gingerbread, get my data going and flash back to cm7 w/out using any new kernel... have to make sure the rom doesn't autoinstall the new kernel either when you flash the rom

Update the apn settings for t-mobile. You can find them online just by looking them up. Try that.

What works for me is a hard reboot. Hold volume up and power for 8 seconds. Apn should be there when you boot back up (usually). I have this issue with stock and any other kernel

SOLVED!
I had the exact same issue and fixed it by installing the SIM card that came in the GX2 box.
I had been using my Nexus One SIM up to that point. The T-Mobile customer service rep told me that the G2X needed the updated SIM card and that without it, there would be data issues when not on Wi-Fi.
Write the SIM card information down before installing it in the G2X and calling T-Mobile (or whoever is your service provider) b/c they need the serial number in order to properly provision the phone.

Worked like a charm!!! Thank you!!
Simple yet effective lol
Finally up and running on cm7 with no apparent issues to report!

Also I found out that going into settings,into the apn settings,pressing menu then reset to default seem to kick it outta limbo

Great info everyone, thanks!
I'm still working on getting the market up and running on cm7, but otherwise everything is running really clean!

Thread moved to proper forum.

I have the same issue, and only on CM7..
Other Stock roms work OK for 3G
I have 2 sims - one uses regular APN setting (supplied from simcard) the other one is manual
The one that uses default (simcard) apn worked once after first install..
Than doesnt work..
VOL up + power didnt do the trick..
Whenever I put the custom APN simcard, it doesnt apply the settings..
Very weird..

I'm using the SIM out of my G2x box. Maybe it helps a little but it still happens when coming from a reboot, wifi, or airplane mode.
When you go to Mobile Networks, it won't connect to any of the listed networks.
This is already known and discussed, but to put a solution to this thread:
Go into Mobile network.
Let it scan
Select ANY network, it will error
Select Automatic until it reconnects again
Done.
Once it reconnects, you should be able to go into APN settings and see "Simple" and "T-Mobile". Sometimes if you can you select "Simple" then select "Tmobile" again, it speeds things up.
Works EVERY time. Sucks it requires this most of the time but it only takes a second and will stay connected for as long as the phone is turned on.

Hard reset (VolUP+Power) didnt work..
Is it a problem with their firmware?
I require custom APN's on my Network operator -- stock (or eagle blood/team bionics) work great, but CM7 doesnt for some reason..
Cant figure out why..
Even 7.1 RC0

APN's won't stick until you do what I said above. Once you disconnected and reconnect, APN's should pop up. If you created your own APN, it should THEN be displayed.
Even customs APN's won't be displayed until you disconnect/reconnect using the methods above.

I feel like we're missing a step here. There isn't anything to select, unless you go under Network Operators or Access Point Names. APN is blank for me, so i can't select anything, and doing anything under Network operators doesn't work...

Aokp data not working?

Does the aokp rom contain a bug where the data wont be able to work or something?

next time ask in the ROM's Thread.
but as far as i know it does not. im using build 31 and its working fine.
try pulling out the battery for a few seconds then putting it back in and booting up.

Same here...data working fine in aokp.

Forgot to mention that there is an issue with data dropping in ALL 4.04 ROMs, including other phones.

The issue behind this here is that for whatever reason, the APN settings always seem to get lost. Sometimes the actually load properly and boom data. Then perhaps you leave wifi on and then most (at least all of the ICS roms I've used) drop the APN.The APN is what handles the data verification.
EDIT: As of recently, I have discovered that data is working fairly well on AOKP. I just reset the APN under its menu, then rebooted. Make sure you're running the correct RIL; it does help. Besides that, I've found that fix permission sometimes screws with APN recovery. So fix permissions, reset APN, and enjoy data coming back.

[Q] No mobile data after reverting from CM to stock

Okay, so I've been searching the net for days and to no avail. I installed the new Cyanogenmod on my Nexus 5 and found it, well, awful. It kept hanging, restarting etc. Now when I tried to revert back to stock, I downloaded the image file from developers/google/com/android/nexus/images, and there's no 4g. No mobile data whatsoever. I can call, the Wi-Fi is working, but no mobile data. I've tried factory resetting, installing a different radio zip etc. When I install Cyanogenmod again, the 4g works again, but after going back to stock nothing again. Any help?

Wow, this is stupid, but after trying everything, including running every new stock rom, I tried installing the 4.4 (KRT16M) AND IT FINALLY WORKED. I'm gonna leave this up for anyone in the same situation as me.

Well, would you guess, the problem's back, but from a different angle. After installing 4.4.0, and letting the device upgrade itself to 4.4.4, the data worked perfectly. Now I tried to install the android L developer preview and again no data connection.
Does anyone have any idea if it could be a regional issue or something? I tried flashing older radio zip files but to no avail, now back to 4.4.0 .

Try setting a new APN with your carrier settings.

I lost connection all together last Saturday. I flashed CM 11,Friday and all was well. Received a call Saturday, it rang once then lost connection. Had to reboot four times to regain service and that was short lived. After any call incoming or outgoing, I lose service. All APNs are present. WiFi works. SIM alert when SIM is removed. SIM works fine in my N4. Did a complete tear down and it's not hardware related.

Sim works fine in my N4 also

If you loose signal might be a radio problem, still if you have signal but no connectivity try with the new APN, android (CM, stock unless carrier stock) had errors in the APN list for my carrier and I had to manually add it each time I used a new rom for several years.

man, i just got off the phone with a robot from tmobile customer service. she had me turn the phone off and pull the sim card, she told me she "refreshed" my service on her end and the problem was "gone". ya, its not.

[Q] Removing saved wifi networks

I have an N5 on 4.4.4, stock rom, franco kernel, xposed installed. just so you have a baseline.
I have this one major problem with it that I've been trying to sort out for... a long time, and nothing seems to work.
I can't make it forget wifi networks.
At all.
I longpress, click forget network, and then a minute later, it will reconnect to it again.
I have 4 different wifi networks this happens with now, which is massively annoying.
I've tried everything suggested by google, such as removing them when they're not in range, etc, and nothing works.
Does anyone know of maybe some config file i can manually wipe them from, or some app that will let me be rid of this blight?
thanks in advance

file you're asking - /data/misc/wifi/wpa_suplicant.conf - (that's in lollipop, but don't think it will different in KK )

Lost LTE and internet access on some Wi-Fi networks after flashing Cyanogenmod

This is the first help post for anything tech-related that I've ever posted- I'm usually good enough with Google to fix my own problems, but this one has me flustered.
Until yesterday I was running DigitalHigh's GPE ROM but decided to give Cyanogenmod another try after some persistent lag issues. Everything went fine during the install until I noticed that I was stuck on 3G no matter what I did- airplane mode, reboot, clear the cache, try to update APN settings, etc., nothing helped. Additionally, while the phone will connect to my home wireless network, it has a ! next to the connection symbol despite my being able to use the network with my laptop. The funny thing is, this only happens with some networks. Neither my home network nor the network at work will give me internet access, but if I plug an ethernet cable into my laptop and create an access point that way, I'm fine.
Here's what I've tried so far after scouring these and other forums:
-Reverted back to the previous ROM
-Flashed new firmware
-Flashed two new kernels
-Tried every different APN setting I can think of
-Popped out my sim card, waited a bit, and popped it back in
-Rebooted countless times
-Cleared every cache I can think of
-updated TWRP
There's probably more that I can't think of off the top of my head as well. Does anybody have any idea what on earth has happened to my phone?
