So I have a 4g problem. In Santa Clara, CA.
I get a decent signal and it holds fine, no disconnects, but there is not data transfer.
Things I tried:
- Checked MAC and it matches the case.
- Deleted tree.xml
- Reflashed Radio and Wimax
- Updated PRL, Profile
No luck with any of them.
4G worked a while ago, then I flashed CM6, then back to stock 2.2.
Current setup: Stock 2.2, netarchy's kernel 4.1.8-cfs.
Any suggestions? Did I miss any fix possibilities?
you're keys are most likely gone.

Oh no, who's gonna let me in the house
Seriously though, what does that mean?
Also, more importantly, is there a way to fix it?
Did you check your connection with speed test? Is the 4G problem restricted only to Web browsing?
I ask because the Ad Free app will block 4G Web browsing, but not 4G anything else and not 3G Web.

No AdFree here. Can not connect to the web or use mail.
So no connection of any sort.

So, installed alogcat, run it. I'm guessing I'm looking for "E/Wimax ....."
When filter by "E/Wimax", I get the following
"E/Wimax ( 730):<DC CONNECT> IO Error:msg='/127.0.0.1:7771 - Connection refused"
Also
"E/Wimax ( 730)<DCP> Bad return status 0xffffffff"
Does that mean anything?

Also keys = rsa keys. When you delete them you're not able to connect to 4g at all.
I had this problem for a while and it was because I was on an old radio and couldn't get the new one to flash properly without wiping thee cache first

Thanks.
I thought that might be the case. So I flashed the new radios, and as far as I can tell they're up to date.
Baseband: 2.15.00.07.28 (from phone info settings)
Wimax: 26023 (from wimax_mtd)
The interesting things is that it appears to be connected, and even get's IP issued, just no data transfer...
I was having the same problem. I did everything u listed above n nothing still didn't work. I was running vael Rom with kings bfc #9 kernel. I didn't know what else to do so I Decided to start from scratch....did a full wipe flash the radio, the wimax and vael Rom again still no luck. So I told myself **** it....then I decided I wanted to try Fresh Rom. So I wipe everything again n flash Fresh on to my phone and now my 4g is working again....I don't knowing that would help u but it did it for me. Hope u get it figure out.
Update: ok so I thought about flashing a new kernel. So I made a NAND backup and flashed netarchy-toastmod kernel. After flashing my 4g stop working again.
Did a NAND restore. Then this time I wipe the delvik cache. Then flash the kernel and 4g is working...

Thanks for the info. Looks like I better get wiping and flashing.
Did you wipe data as well or just the caches?
Wipe data and cache when flashing a new Rom.
Wipe dalvik cache when flashing a new kernel
Same thing happened to me. I ended up flashing the RA Recovery because I heard CW wasn't wiping cache's correctly. So you might want to try that as well.
I tried wiping both caches 1-2 times multiple times and it never worked. Then one time I wiped both caches 3 times and it worked.

I have tested my 4G datacard from Sprint in that area (top of Palo Alto), where I had 1-2 bars of 4G signal.
Because they are still testing there, I was unable to connect...
This might be your case -- they are still testing, and probably turn connections on/off during this period.
Best of luck though!
This 4G problem happened to me...i dug around in my backups and found a wimax.img from nandroid folder on sdcard. You need to find an older wimax image that was created during a back up...these wimax.imgs that are an image of your phone HAVE YOUR WIMAX KEYS
Hi all, I'm running CM 7 stable with latest radio (7.15.35.16) and 2.6.32.17 kernel. I I wiped data, cache, and dalvik cache before flashing cm7, then the appropriate gapps. The problem has been ongoing with other cm 7 RCs, but doesn't happen in 6.1.1. I am able to connect to wifi networks, but I can't load or reload anything in any app. The icon stays white/gray on the status bar instead of turning green like the data network icon does to show it's fully working. Tried the android dev forums, but haven't found anything that fixes this. Any help would be much appreciated.
<strike>So I found a way for data to work while on wifi. I have to enable gps and have it lock on in google maps in order for the wifi to send and receive data instead of just being connected and doing nothing. Don't know much of the code stuff so if anyone can figure that one, be my guest!</strike>
Thanks to ilostchild for the fix in the last post. Pull 'tiwlan.ini' from cm6.1.1 and push it to cm7. Located in System>ETC>WIFI folder. Mount system before pulling and pushing files. Good luck!
I believe your kernel is geared for FROYO not Gingerbread. You might need to reflash the ROM and don't flash any "new" kernels as of yet. It may break your wifi.
This is the kernel that came with CM 7, unless I'm mistaken. But I'll try the re-flash option. Update later. Thanks for the suggestion.
You're right, i'm an idiot haha. Have you synced your google accounts to your phone yet? The green and grey signifies your connection to google servers.

I did. I did see the green and grey while on mobile network, but only grey when on wifi. Should I not let the phone restore everything once I reflash? I might try that and make sure every aspect of the google account syncs before attempting a wifi connect. Either way, I can always go back to cm 6.1 Thanks.
Try nightly 39, I read that was fixed in it. I didn't have the problem so I can't say if it was.

Would you be able to make a flashable zip with the stock wifi files? I've been having problems with CM6 and 7 wifi.
I don't think anyone has ever had a problem with the stock rom wifi. It would solve nearly anyone's problem.

The stock wifi files wont work with cm7, because cyanogenmod uses mostly generic drivers for things we dont have source for. Have you tried formatting the system in recovery? format everything except your sd card, reflash cm7, then add the twlan.ini from cm6. thats what worked for me, and i was one of those "unlucky ones."

Did you wipe data/cache before flashing? I would also try flashing a stock ROM to see if that works... Could also try to just flash the radios.

i should have been more detailed, but was short for time and was on my touchpad. I did in fact wipe davlik, as well as data/cache.
I also reseated the sim card. 4g always worked fine on stock rom. It was working just fine on cm10 before the newest stable. I removed it and flashed pure aosp 4.2 rom and it was working then as well. I went back to cm10 with a clean flash and it again was not working. I am now on xenon hd 11-25-12 rc1. It is now working just fine. i always tended to stick with cyanogenmod and never had a problem like this before. I am not sure why i am experiencing this poblem now. I was not sure if this was a bug that others may have been experiencing..
No I dont believe it is a bug because I am on CM10 on the VZW Gnex and I have not had any problems with LTE, mine is working fine.
I'm having the same issue. 4G was working on my Verizon GNex on CM10 however it stopped working.

No change :/
sorry, not too sure then. only thing i would try is use the superwipe script on top of manually wiping your phone and reinstall the rom.

I have a Sprint GNex on Page Plus Cellular (Verizon MVNO) and a Verizon GNex on Verizon. The phone in question is my Verizon GNex.
I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.
Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

This is something wierd with Kitkat. I do not believe a fix has been found just yet. but if you dial *#*#info#*#* on most phones you can get into the phone systems and turn LTE back on.

KitKat roms are currently having data issues. You could try backing up your current KK rom and go back to Stock, update prl and backup your DNS settings then go back to your backed up KK rom and restore from the dns settings you backed up.

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^
Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.

Before I start let me explain I've searched for the answer to this and have yet to find any concrete answers. I've had my Verizon G'Nex since release and had it rooted before Best Buy had even run my credit card. I've been running SlimKat 4.4.2 Build 5 official and CWM Touch. Ever since I updated the ROM (clean flash) to the 4.4.4 experimental I've had problems with both 3G and LTE connecting to data. I have signal, in some cases "4 bars" worth, but it never actually connects to data unless I reboot the phone - that will last for a couple hours to a couple days then it's back to no data. I completely wiped the phone - data, cache, system, and sdcard...everything that CWM could possibly let you wipe - and then sideloaded the previously stated Slimkat which worked for months prior without issue. The problem still persists, and has gotten worse. I cannot use LTE at all. It will not connect regardless of what I do.
So my question here is what parts of Android affect data connection? Is this entirely ROM dependent, or does kernel have something to do with it? I'd rather not go through the trouble of finding another ROM that has speed and features of SlimKat, or randomly flashing kernels just to find it doing the same thing.

Well in not sure about this option being in your version of cwm.
However if it has wipe efs data as an option and you wiped it nothing that you do to try and fix your connections will work.
I found this out the hard way and had to buy a new gnex. Tried everything but couldn't get my efs data back.

No option about EFS. That's the thing that bothers me. I have voice and text, it can 'see' towers, it appears to be able to 'connect' to towers, but it's like it's not pulling an IP address or it can't contact DNS.
