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...

Unreliable data connection

I'm having this weird problem with my G2x where my connection to T-Mobile's data servers has a mind of its own. Sometimes, I'll have no problem booting up into (or switching from WiFi into) a stable data connection, but at others, I can't find for the life of me a way to get it working correctly/normally.
I've had this with every ROM/kernel I've installed since I rooted it on day 1. I don't remember if I had any problems back on stock ROM and kernel, but it looks like I'll soon be unrooting and restoring to find out.
Another (possibly-related?) symptom I have is that my APN settings are forever cursed to be blank. There are no settings listed and I can't get any ones that I add to save. I got an APN manager app from the market that showed I had the proper APN settings up and running. Therefore, I'm assuming this is not the cause of the problem; otherwise, how come it is indeed connected to data services? Correct me if I'm wrong.
I'd also just like to say I'm not the only one experiencing this. I've seen a handful of other posts throughout the G2x threads that are reporting the same connectivity issues.
Any ideas what's going on? I've tried most of the basic stuff:clearing cach, rebooting, wiping Dalvik cache, fixing permissions, etc. I'm starting to believe that there was a batch of G2x's that came with manufacturer defects that were unknown until now.
EDIT: Solved this problem myself. see this post for more info.

please help me to understand what is going on

Basically this is a WiFi issue with all CM10/AOKP fresh installed after Sep the 11th.
I said Sep the 11th because that is the best refference I can find.
If I flash any CM10?AOKP based ROM released after that date I lose wifi on 1st reboot after initial setup. To get the wifi working I have to toggle on the wifi manually, or toggle off and then on or reboot. I could not find a pattern. At the end the problem is that the wifi does not start on boot by itself. Let me be very clear here. Fresh flash.
Now here is the strange thing. I have several nands for Paranoid, CM10, SlimBean (unfortunately none for AOKP), taken pervious to that date and if I dirty flash to the last release everything works fine. No problems with the wifi.
The stock ROMs all of them work fine, fresh or dirty flashed.
I googled the internet and checked xda and other forums. I found just couple of similar situations but with no working solution .
One of them says that you have to odin back to stock, connect to wifi and then flash CM10. I did that and no go.
I tried different routers in different wireless configurations, same problem. Static ip and stuff.
Sometimes I get the wifi network "not in range" or the toggle for wifi in setting semi off or on.
If this is a wifi driver problem then:
1. can I get an old CM10/AOKP driver injected to the new releases?
2. why when I dirty flash the old driver (present in nand) does not get overwritten?
3. did you see anywhere a similar problem or it's only me.
Thanks in advance for your help.

same issues here on any build of aokp. wifi works until after a restart. i get the out of range error or wps failed. i have to shut off wifi and turn it on to connect. really annoying. funny thing is on ics i have no issues with wifi auto connecting.
ideas? Kinda weird only a small handful of people have this going on.

I've noticed WiFi issues also while on cm10. Lately I've noticed WiFi becoming better in more recent nightlies. However I've been doing clean flashes, and not restoring any system settings from backups. Even unclicking the boxes from the initial startup that allows Google to backup and restore settings on the phone. I'm assuming that possibly some setting/config is being restored causing the issue... just a thought

Nope i dont restore anything and always do a fresh clean install. If i had to guess its a buggy wifi driver that causes issues with certain routers. That would explain why very few have our issues. I guess for now ill stick to beans rom and wait for the jb ota.

Its worse than i thought as i have this issue on all the aosp varients. I just tried cm10, all aokp, liquid and slimbean. Same wifi error. I nandroid back to beans ics rom and everything is fine. Its got to be a wifi driver issue. There has to be more than myself and the op having this issue.

Permanent Fix for intermittent data issue on CM9/10/AOSP 4.0+ based ROMs

After months of having this reoccurring issue myself, I FINALLY figured out a solution. It had gotten so bad on mine that wiping the rom won't matter... the only solution was to wait for several minutes/hours until it returned or switch to a Sense-based or a GB rom. This fix should appeal to those who had to return to older roms due this issue driving them insane!
Let's clear up a few things first.. to those having this issue and being able to restore data by going into airplane mode might wanna invest in a new sim card. Best to go into a retail location and pick one out yourself. The newest ones (model number TM9177 or higher) work the best and have the fewest data drop offs. That should fix a lot of users intermittent data issues from returning.
If you still have data issues and already have a newer model sim card (TM9177 or higher) OR have data issues that don't get fixed after a reboot, switching into airplane mode, wiping, normally have to wait a long time for it to return on its own, etc.... then this part will fix it. :highfive:
Go to home, menu, settings, wireless & networks, more, mobile networks, access point names, menu, and FINALLY add a new apn. Chose whatever for name of apn (maybe tmobile alternate, tmobile 2, or whatever), the next line, the actual apn, with be "wap.voicestream.com" (no quotes, duh). Next add this line to MMSC... "http://mms.msg.eng.t-mobile.com/mms/wapenc". Everything else should be left as is. Now hit menu, save apn. This new apn seems to work with all features I've tried... text messaging, full data access, same speed as default epc.tmobile.com apn, tethering, etc. Haven't tried MMS but the settings for that line is there in our alternate apn we just made. Please post results on that if anyone still uses that feature So... that's it. The old apn works nicely and you say GO TO HELL! to the annoying data icon flashing on and off forever!
Be sure to post your results/experiences to confirm but it seems to be gone on 4 other MT4GS CM9/10 users besides my own. I REALLY HOPE y'all are as happy with this fix as much my family, friends, co workers, and I are! Do forget to use the thanks button
Also... you can try "internet.voicestream.com" for an additional apn. I'm not sure if MMS will work on that one even with the MMCS set as "http://mms.msg.eng.t-mobile.com/mms/wapenc" but it's work a try. If anyone wants to check it out is welcome to. Again... post your results. I'm not sure how long tmobile will leave these old apns active but I bet it's longer than anyone will be still using this model lol! Enjoy!

I've been one of the lucky ones not to have had this problem but if this fixes the issue of those that have been, this is one NIIIICE CATCH! GOOD WORK, sino8r!!
I'm very anxious to hear how this works out for everyone!

Intermittent Data 3G 4G Loss Disconnect
Wow, Thanks. I've been fighting with this all day.
I've been running SilverL CM 10.1 for a couple of weeks and today suddenly lost my T-Mobile data connection.
I tried many solutions (I wish I'd found this thread sooner). Wiping Cache, Fix Permissions, Reflashed, different Kernals, different loads. Going back to Gingerbread worked, but I lost the data when I went back to ICS/JB.
There was even another thread that was close with deleting all APNs and creating a new one, but the settings still weren't there.
This took care of it right away.
THANKS !!!!

Tested it with 2 diffrent JB roms fixed data problem in about 10 seconds from selectign new APN. Data speeds are back to normal! Will update if anything changes.

After several days even weeks of no issue then suddenly I get data issues again so I go back to mobile networks to find the second APN I created to be deleted... Anyone experience this?

thanks for the info! i ran across this thread while searching for a new ROM for my mytouch 4g slide, hoping it would fix the issue. once I arrived to the access point names, i noticed that the apn selected was for LTE. I switched to the regular one and now it works great. thanks!

I had this issue while on cm9 releases but it had gone away after I began using unofficial 10.1. Sort of. In certain areas- and I assume with certain towers - my data wouldn't work with some apps (ie., Facebook, Google maps) even though the data icon would show "H" or "3g" locked on and blue consistently. Sure enough, this fixed it right up.
Also, although my phone shows the option for the Tmobile lte APN in the settings, it was not selected by default. Thanks for this!

[Q] Wifi Hotspot not working after installing CM9

I installed CM9 on my phone and it seems to be working fine, except few issues. One issue is that when I enable WiFi Hotspot, it fails to start.
When I go in settings, I can provide settings for WiFi Hotspot. After that, when I enable it, I see in notification area that wifi is being disabled, but after that hotspot option becomes enable again, wifi remains enabled and not hotspot is available for my computer to connect to.
I installed a teethering app from Play store and that works, but that creates an adhoc network only. I was able to use wifi teethering with HTC image, before installing CM9.
I have S-ON.
Does anyone else has seen this issue, especially with Cyanogenmod 9 Stable (cm-9.1.0-doubleshot.zip) on this phone

I've been using the CM9.1 + drain fix + USB fix ROM you'll see in the development section since November. I'm on r8, but they're up to r9b now. This is much better than the plain CM9.0 for our device as it fixed a couple of major issues like battery drain and slow USB transfer rates. I used WIFI hotspot and tethering for the first time last Thursday, and it worked first time no problem. No additional apps needed. Got my laptop hooked up to the internet and able to VPN into work network in a moving car (somebody else was driving honest!). Not sure if that helps answer your question directly, but it certainly works in CM9 series ROMs, and if you don't have 9.1 you should go get it1.

Thanks davidf9. I will try CM9.1.
From where I can get drain fix and USB fix?
Couple of other issues, I am seeing are: 1. no keyboard lights for caps lock or Alt buttons. 2. For some reason my barcode/QR reader/Google gogle apps are not able to lock on bar codes and when they snapshot they get scrambled image. Also, some other apps (like 3d compass) having distorted view from camera. Camera app itself working fine.
Have you see any of these issues with CM9.1?

The battery drain and USB drain fixes are built into the ROM by scverhagen, you don't need to separately apply them.
As to your other questions, the caps and alt LEDs don't work for me either I just hadn't noticed! I don't have any problem with my QR code scanner, but I don't use the other things you mention so can't comment.

I installed scverhagen's build cm-9-1-(3-0-53)-r9b.zip (MD5 1c16aafa8d0220d44b5b7ea22e7fb24c) from http://forum.xda-developers.com/showpost.php?p=32192055. I cleared Delvik cache, battery stats cache and cache partitions before installing it.
It fixed camera / QR Code Reader issue, but HotSpot issue is still there.
I did some more research and found some suggestions about "fixing permissions", turning wifi off and rebooting. I tried these and got Hotspot temporarily once, but on next try it failed.
I guess I need to collect logs and see what's going on. Thanks for your help.

You did a factory reset/wipe while in recovery as well didn't you? Several guides around here recommend doing the whole sequence several times over. Look for some of Strapped365's posts.
As I said, the hotspot worked for me first time, no problem. Just what was built into CM, no new apps. Must have been lucky. Sorry can't help further.

I didn't do a Factory Reset this time . I did that for when installing Cyanogenmod ROM, but I didn't had time to reinstall all apps and do all the settings again this time around. May be I will retry on weekend.
Thanks for the great help.

If S-On, you'll always have to fastboot flash boot boot.img thru ADB or your network never will work.
The PROPER way to wipe before a flash is as follows:
1. Wipe dalvik TWICE.
2. Under 'Mounts & Storage' format system.
3. THEN factory reset on the first CWM page.
These are the minimum requirements for a complete wipe.....

Thanks. I didn't do step 3 for this ROM installation. I am thinking of taking a Titanium Backup of all the apps, following your steps and then restoring apps after installation.
I am hoping this will save me from hassle of re-installing all the apps and configuring them.

That it will do. Just be aware that reinstalling them in a different ROM with their data sometimes causes an issue with an app. It will put them all back though....just not on your different pages that you may have them on.
