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...
Hello. After lots of rooting, ROM flashing, and all that good stuff, somewhere in the process I did something that must be keeping me from using 4G. When I turn on my 4G antenna, in settings it just says I'm "Disconnected" and when I scan for service, it scans for maybe five seconds and goes back to disconnected. In the settings, all three fields for 4G network information (Network provider, Signal strength, and IP address), are blank.
I used wimax_mtd and ls /data/misc/wimax/ to make sure I still had my keys, and I do, they match what's written on the back of the phone exactly. I tried this with no luck.
Anyone know what is causing the problem? I'm running a fully rooted gingerbread.

What rom/version? What provider? What troubleshooting steps have you taken?
Sprint. The ROM is just a rooted version of Gingerbread (2.3.3). The software number is 2.76.651.4. Troubleshooting? I don't even know what you're asking there. I have my keys, I've confirmed that. I tried one thing from the thread I linked. I can't connect. What else am I supposed to try?

Flash the new radio/wimax radio, update profile/prl/twice/reboot twice, tweak ##DATA# settings.

Unless your actually connected Network provider, Signal strength, and IP addresswill appear blank when you look in settings. If you've confirmed you have your keys, and are in a 4G zone. Then you can try a simple trick that sometimes works. Put the phone in Airplane mode for a few minutes. Then take it out of Airplane mode, and try to connect to 4G. If that doesn't work then go ahead and update the radios as VICODAN said. That should solve the issue.
Still no luck
I just tried all of those steps, besides the airplane mode one, with no luck, but I'm trying the airplane mode idea right now, and if that doesn't work, I'll elaborate.
EDIT:
Okay, no luck.
So I went through and flashed the newest radio and the wimax radio, and in the process I realized that I didn't actually have the newest radios beforehand. (I also learned that I hadn't yet formatted my microSD card to FAT32, so it's good that I realized that too. ) After that, I went into System Uupdates and updated Profile and PLR, then I rebooted, and I did it again, and I rebooted. You said to do it twice, so that's why, but you said twice twice so I wasn't sure which part to do twice. (Wow, that was a mouthful.)
After all of that, I tried the airplane more thing, with no success. I've connected to 4G in the past here, and the spring website even says my area has 4G coverage, so I know that's not the issue.
Also, about the tweaking ##DATA# settings, I mentioned that I tweaked it according to the link I put in the original post, but is there anything else I should try?
Thanks for the suggestions so far.

Last thing to try is ##rtn#, wipes fone and resets to factory defaults, then do hands free activation.
Also make sure your [email protected] stuff is configured properly. This is also somewhere in ##DATA# settings.
You can also try flashing a different rom like CM7
But before you do that call sprint tech support and tell them to fix it. They might be able to do something on their side.
Okay thanks, I'll call them later today.

So I called, the woman had me do a few things, and after hitting restore from the menu in ##DATA#, the 4G is behaving differently. Instead of scanning and returning to disconnectec, it now goes to "turning on ..." Then to "turning off ..." And back to on again. It cycles forever, until I manually turn it off.

Well it sounds like something is still wrong. Try flashing a different Rom to rule that out. If that doesn't work, and having WiMax is a must. Then you may want to think about running an RUU back to 2.2 stock. Then just start the whole root process all over.
Hi
i have installed this awesome rom "Updated 3June12 [ROM][2.3.7][CWM] HebrewValhalla V3.4"
The word smooth has a sense
I have a signal issue.
when i go to an elevator without signal, the signal don't come back.
I have some bars in the signal bar but when i tried to call, i am getting Not Registered on network
it's not a sim issue, i have already replaced it.
Any ideas?
Did you try a reset and full wipe?
Your phone is picking up another network. Used to happen to me all the time. ATT has a stronger signal where I live and my phone would lock onto it for hours at a time. Didn't matter if I manually selected the carrier or not. After hours on the phone with Tmob they finally let me out of my contract.

If you were on a contract plan shouldnt it pick up the att towers as "roaming" since your t-mo towers werent as powerful?
If that is whats happening it explains why I cant get service in walmart. Im on the prepaid plan so no roaming for me.
No roaming agreement between ATT and Tmob at the time. It was right when the merger was being proposed. I confirmed it with Samsung as well. The device will look for the stronger network and try to connect to that. The crappy thing was you couldn't override it. I'd force Tmob as network and as soon as it dropped signal it would revert back to ATT.
Did you try flashing another modem? This ROM comes with sidekick KD1 modem. Some people prefer our native KI3, KJ1, KG4 or KJ6 modem.
I would also try to disable roaming option abd force a network.

Hi
Thanks for your answers
First, i am is israel. i am subscribed to the orange carrier
i have tried the wipe, the fix permission, the clean dalvik cache
i will follow your advice. i am flashing the Kj6
wait and see
If nothing else, one thing that works for me when I completely lose my network is to do a hard reset: Pull the battery, hold power button for 15 seconds, leave battery out for 10 minutes, put battery back in, boot and let sit another 10 minutes. Fixed.
Haven't had the issue on a bml ROM though(such as Valhalla), not sure if it's coincidence, but if all else falls, hopefully it will help you solve the issue. I tried flashing new modems, permissions, wipes, formats, flashing new ROM's, and that was the only thing to actually restore the network (restoring my efs may have worked, but didn't try it then, and that would only be applicable to an mtd ROM, unlike Valhalla)

Also try to switch it to GSM only, it might work.
when am selecting only GSM, the 3G don't work. i only get the G
BTW, each time that i restart the phone, i have to enable the GSM/WDCA.
after each restart, the phone is automatically configured to only GSM
Hi Guys
i am driving crazy
I have followed all those steps
1. Put ROM zip in SDcard.
2. Go to recovery mode.
3. Perform Wipe cache partition (3 times).
4. Perform Wipe data\Factory reset (3 times).
5. Perform Advanced -> Wipe dalvik cache (3 times).
6. Perform Voodoo -> Disable Lagfix.
7. Perform Voodoo -> System Lagfix Off.
8. Perform Install zip file - choose Hebrew valhall 3.5ROM zip.
9. Allow ROM to start, mount mount points, flash kernel and finish.
10. Go to 'Voodoo Settings'.
11.Perform Voodoo -> Enable Lagfix.
12.Perform Voodoo -> System Lagfix On.
13.Perform Back - Reboot System.
14. Let device stay untouched for 10 minutes.
Now i have another issue, each time that i restart the phone, i have to enable the GSM/WDCA.
when only GSM is selected, the 3G don't work. i only get the G
after each restart, the phone is automatically configured to only GSM.
Moreover, i don't have the standard gps issue of long lock.
( i have made the AngryGps Fix)
when i am using Waze, i am losing the Gps Signal
SOS
G.
G.
RESOLVED
i have enabled bluetooth wifi, Gps and restart the phone
and the issue is fixed
Is "netword" a new game like Scrabble or something?
Hi Heniki
I was on Israeli Orange and everything worked just fine. Now I'm on Rami Levi just paying 75% less..
Anyway, I suggest :
1. Try the Gremlin remover.
2. Re-flash ROM afterwards (try other ROMs if you must).
3. Check if your SIM is OK (try it with other SIMs).
4. Maybe SDCard is causing problems ?
The only problem I ever had with connectivity is that sometimes WiFi/3G/BT didn't want to start and the workaround I found at that time was :
1. Set 3G and BT on and restart the device.
2. Once device is up, turn BT off and 5 seconds later, turn 3G off.
3. If you want Wifi - just turn it on.
If you want BT - turn Wifi on, wait 5 sec, turn BT on. wait till it's up and turn Wifi off if you don't want it. Once you're done with BT, turn Wifi on - turn BT off and then Wifi Off.
4. If 3G/Wifi don't turn on, leave it on, set flight mode, wait 10 sec, then set flight mode off. It will work.
I don't have these issues lately (I'm on AntonX's 1.1.2 kernel).
If you must have a Hebrew ROM, know that I will publish a Hebrew CM7 and Hebrew MIUI next month.

Ok here is the problem... I rooted the phone, played with some settings, explored the android platform in general. Somehow, my data has stopped working. I can make calls and send texts no problem, when I try to access internet or google play store, it fells me that I have no data connection available or something of the sort. I have tried flashing different roms, played around with switching between Global and Lte/cdma radio bands. When I switch bands, I get either 4g or 3g, but within half hour it stops working again. After a restart, same thing happens, it worka and then atops. I figure there is something messed up with the modem. Please advise.
Also, anyone else experiencing sudden restarts with CleanRom 5.0? My phone reboots every once in a while for no apparent reason.

Looked into it a bit more.... my 4g or 3g works after a restart as long as there is a demand for it, ex. While surfing or streaming radio, as soon as there is no demand, the phone shuts it off and I can't turn it back on. It tells me no signal found for mobile networks. While voice and mssg still work. I refreshed the modem and that didn't help. Short of going back to stock, any other suggestions?
Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.
