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.

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

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...
Flashed CM7 the other day (thanks again for the help Carmon!) and love it. Only issue I am having so far is...I've been unable to roam. I live in a fringe area, and normally roam on Verizon towers at home. I attempted *228 several times (while on US Cellular), and the recorded message (voice) states that the update was successful, but the message on my screen says "activation unsuccessful". I am able to make and receive calls and send messages, etc...but the phone will not roam. I have networks set to automatic, and national data roaming enabled. Any ideas?? Anyone??
The screen always says unsuccessful, it's a known glitch. Try setting roam options to home only or whatever, sometimes they get mixed up in the process of building and fixing other stuff.

Appreciate your response! I've tried every setting. Home only gives me US Cellular signal. When set to "Affiliated Networks", the setting will not remain there, it resets itself to Home only. When set to "Automatic", it catches US Cellular signal, but does not roam when there is no US Cell signal.
Surprised nobody else has this problem...
It may be a issue in which we need to go all the way back to stock and do the ADW fix.
Yeah possibly... scarmon do you have that to post? Ive never had to do it and I never copied it down...

Seems that fix is for phones that are always roaming. Is it known to work for the problem I'm having also (no roaming)??
Just got done flashing back to stock and completing the ADW fix. Flashed back to CM7...still no roaming. Tried every setting and every combination of settings with NO luck.

That's really odd... are you sure you're in a roaming area? The phone wont roam if you have uscc signal.
Sent from my MIUI SCH-i500
I am in a roaming area...as I mentioned above, I live in a fringe area, and my phone (usually) constantly switches between US Cell and Verizon. Now, it does not switch...it just goes from US Cell to NO service.
On another note, since I re-flashed, I am not receiving sms. And when I send sms, they are blank???
When you went back to stock did you flash the EH09 Build or did you flash EE19.
Edit. Didn't mean to double post
I did a full flash back to stock Froyo since I had the files already...
Everything is working except sms...
First off what's weird is that in the Access Point Names it shows Simple Mobile(which I use) and T-Mobile. Usually when I flash a new Rom it only shows T-Mobile.
Secondly it will not let me edit any of these two APNs.
Still no service when I have the little bubble checked on either one. What's going on?
nothing?
I am going to say this even though you probably already tried it, but have you tried doing a full wipe and reinstall? If not this could fix the problem. Are you able to see the percentage of your battery? If it just stays at 100% and never changes you should look in the about phone in the settings and see if it can see the baseband as no baseband no ability to read battery and no working network abilities. If you can't see the baseband then get the app called GetRil and see if you can get a compatible one to get yourself back up and running.
If none of what I said above applies to your situation then you should try a different kernel. I am running EB AOSP 4.0.4 build 2.5 with the Harsh kernel with no problems.

I have a similiar issue just the variables are slightly reversed ( I am on T-Mobile, don't even know what Simple is, using GB roms, not ICS) Even made a similair thread on here. 2 Things, are you shutting down and then booting up or are you rebooting. I only get my data back when I reboot. I can't shut down and manually restart.
Secondly, when you go into the about phone section, does your mobile data network section say connected or disconnected?
I've read a lot on the internet but have not found a good answer for me. In certain locations, almost daily, I get either a "not registered on the network" message or a "sim not allowed ##3" message on my Infuse. If I switch the phone to airplane mode and then back off of airplane mode it always reconnects to the AT&T network. The problem started after I changed my ROM from Infused 1.5.3 to Zeus 6. I've flashed to Mind of Mac 1.4 but that didn't fix the problem. I've tried a new SIM card, different APN settings and several other changes, but it didn't help. If I have a good 4g connection it never has the problem. It never re-registers on the network until I do the airplane mode on and off thing or reboot the phone. My iemi number shows up weird on the phone too. What is the best way to fix this problem? Thanks.
No one has a clue?

I currently have UCLB3. I have tried a few different ones but it does the same thing with each one I've tried.
Sounds like you know what you are doing , unfortunately it sounds like a hardware issue. If going to settings > mobile networks > network operators and choosing AT&T does not fix it the only thing to suggest is return for repair or exchange. As you know, you will have to return it to stock so after you do that you may want to test it one more time. Sorry, not the answer you wanted but the best answer I have, Regards.

From recent experience - I would avoid using the fixes listed above as they will change your IMEI.
I say this as I was having a similar issue -- I had been running on the ParanoidAndroid ICS rom for a few days and my I997 started to do the same thing. Network connection was fine most of the time but it would occasionally drop out to no network. Except swapping between airplane mode didnt always fix it. If i rebooted the phone and it would pop up with "Unknown" Baseband Version, and no IMEI/IME SV until it connected again... whenever it decided to do so.
I flashed a few different modems to no avail.
Used GTG's stock restore... and it still showed no baseband or IMEI.
Searched through everything i could find and I found the 2 above posts. Being the cautious person that I am, I was skeptical to run the "fix" since I know playing with the efs folder can do.. fun things.. I backed it up with EFS Pro.
http://forum.xda-developers.com/showthread.php?t=1308546
So after that - I did the fix from those two posts. It worked. I got a signal. HUZZAH. But I could only make a few calls before it would drop out, and I couldn't send or receive text messages at all they would just stall and error out.
So I took a look at the IMEI again and noticed that it was NOT *my* IMEI, it was presumably the imei of the person who Truckerglenn got the backup from so long ago.
Figured at this point my phone is going to have to go back to Samsung to fix since it's still dropping out, the IMEI is wrong and I can't send texts
Can't break it anymore than it's already broken right?
Go back into root browser, delete the EFS folder entirely. *poof* gone. Reboot. Use EFS Pro to restore the backup I had created (GOOD THING!) phone reboots. Instantly picks up the signal again, I get 15 text messages, 2 voicemails AND my IMEI shows what it should be now.
*HOPEFULLY* it holds onto its connection now. If not, back to stock and back to samsung it goes - now with the correct IMEI. heh
Sorry for the long story
Thanks! May have found a partial fix.
Thanks for the tips and information. I think I may have found a partial fix. It seems that picking the "WCMDA only" in the "Network Mode" options seems to solve the problem for me. If it is set on "GSM/WCCMA (auto mode)" option, it seems to cause the "SIM not allowed ##3" or the "not registered on the network" problem when I am in an area where the 4G or 3G signal is weak. I will do some more testing. It appears that if I don't have 3G or 4G available in any given location my phone won't connect to the cell towers at all even though other users can connect without any problems. Does this give anyone any other ideas? Do I possibly just need new APN settings?
Have you tried flashing a new radio? Does a complete wipe and restore to UCLB3 make any difference?
Has any of these roms/firmwares that you flashed been done so through Aroma installer? I know Aroma gives you the option to change modems, and if your download was buggered that could have caused it.
I'm just tossing ideas around here... I'm up early and looking to help.
The work around works
Yes, I have flashed the radio but that didn't help. I have discovered the "fix" is to set my phone on "WCDMA only". It seems that the phone will only work if 4G or 3G is available. I am not longer getting the original error messages. So that's a good thing. If I ever go to where 3G and/or 4G is not available I will have to try something else. Thanks for all the replies.
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?
