[Q] White Icons Data/Reception Problems

I'm helped a friend install cyanogen mod 7 stable on his G2 and he told me this morning he lost the ability to go online. The icons show H, but they're in white and cannot access the internet.
I got his phone back from him and sure enough, data doesnt seem to work.
I've followed these steps thus far:
1. Reconfigured APNs - added the one with the proxy 216.165.155.50
2. Installed a new radio - 26.04.02.17
What else can I do? Should I wipe the entire system and restart? I was dreading doing that, but I'm stuck right now. Anybody have any opinions?
Edit: I've searched for a few hours and came up empty handed, please guide me in the right direction.

Try turning off Mobile Data and then turning it back on. If that doesn't work, with Mobile Data on, try turning wi-fi on and then off again.
Then try a reboot.
If still unresolved after the reboot, do a wipe/reflash.
If still unresolved, make sure the radio on the phone is compatible with the version of CM7 you are flashing.

[Q] Data and Phone network connectivity problem

My Verizon GN is having difficulty connecting to my phone and data networks. It all started on the day of the outage this week. I assumed it would all fix itself, but it has not. I've snooped around the board quite a bit and it seems all other users have had their connections restored.
I first noticed the problem on Thursday morning. My data status in notification bar would drop to display no "bars." It does not switch over to 3G. I figured this problem would resolve itself once Verizon fixed its network.
Then I tried to send a text and it couldn't be sent. I tried to call someone and it would not dial out.
But these loss of connections are not persistent. Eventually, the 4G works for a bit then disconnects again.
The phone network seems to be doing this as well. Sometimes I can call/text, other times I can't.
I was considering wiping my phone and flashing a new ROM or getting the stock ROM from google to flash. However, I seem to be having trouble with clockwork mod. When I try to reboot into recovery mode it takes me to what I assume is download mode (shows an android knocked over on his side with, I think, a red X).
Is there something simple I can do to fix my data/phone network connection?
If I have to flash back to complete stock, then how do I do this without being able to access recovery?
If all else fails, will I be able to do a factory reset considering the current scenario? I assume I would need to do this before bringing it to Verizon for service.
I appreciate any help provided. Here are some other details that might help.
Rooted with stock ROM
4.0.2
Baseband I515.09 V.EK05 / I515.EK02
Kernel 3.0.8-gaaa2611
Build ICL53F
/edit/
I should have mentioned I had the most up-to-date version of CWM. I just reflashed it with ROM Mgr and it booted into recovery, so that's good.
Well ****. I went into CWM - Advanced - Fix Permissions. I thought hitting Fix Permissions would bring up another menu. Instead it fixed permissions. Hopefully I didn't do something stupid that I don't understand.

I flashed the GummyNex Rom hoping it was a kernel issue or an issue resolved by going from 4.0.2 to 4.0.3. It's been a little better it seems, but it did drop both networks once already and it's only been 15 minutes or so.

The new ROM definitely did not solve anything. I don't know what to do. I need to find a way to get back unrooted, unlocked, stock. Unfortunately, I'm running Mac OS X 10.4.11 which current SDK doesn't seem to support.

[Q] Sprint Galaxy Nexus; signal/3G issues

Sprint Galaxy Nexus
4.2.1
Not rooted
I performed a factory reset on my phone yesterday due to it bogging down and being rather slow. I never did a reset after getting the 4.2.1 update so I figured it was a good time. I woke up this morning, putzed around the house, and setup Tasker again. I laid my phone down for ten minutes while I got ready for work. Whenever I tried to wake my phone and nothing happened. I tried a few more times and the screen would not wake up. I pulled the battery, hard reset, reinserted battery and the phone wouldn't turn on. Then, I wiped the contact terminals (on the battery and the phone) and reinserted the battery and the phone booted up. However, since then I have had some major problems.
1. Power button does not always work properly. I have to press it several times to sleep or wake the phone. (Okay, not major, just inconvenient and probably unrelated to the issues below)
2. No data connection whatsoever.
3. In the data usage menu, there is no longer a data toggle switch.
4. Under the Network Mode option, LTE/CDMA produces absolutely no cell signal whatsoever. I have to switch to CDMA only. (WiFi works fine)
5. Toggling airplane mode, as some have suggested, does not cause the phone to connect to mobile data. Another factory reset did not restore mobile data. Rebooting did not restore mobile data.
6. All of these problems are true before and after factory reset. No new problems were created and nothing was exacerbated as a result of performing a factory reset.
I've been from one end of the internet to another looking for solutions to this problem and I have found that many are having a similar issue but toggling airplane mode or rebooting fixes it. Not the case for me. Most also seem to be having this problem after rooting. Again, not the case for me.
Any suggestions? I would prefer to not return the phone. Purchased from Radioshack and the 30-day warranty has expired. This is my second gnex already, as the first one's charging port broke. It took over a week to get this one from another store which graciously shipped it in to my store. There's also the issue of being broke and not really being able to afford another $30 activation fee on top of the deductible for a new phone.

Why not try reflashing the stock image and updating again to 4.2.1?

Not at all. You'd use Odin . Myself I have very spotty sprint signal in my home. Spoke to a corporate executive and they mailed me an AirRave free . Never have less then full bars 3g all around home. You should a- flash to stock using Odin following posts in sprint sextjon . b - call up and try to get an airavana.

Excellent. I will give it a shot at some point today or tomorrow and then let you know how it worked out. Thanks!

So, I restored the phone to stock. Signal is still non-existent on LTE/CDMA mode. Cannot perform Profile or PRL updates. Still no mobile data. I'm guessing hardware failure?
Also, on setup it asks for a SIM card. And at the bottom of the drop-down menu, it says "No SIM card|Sprint" or "No SIM card|No Service" depending on if I am in CDMA or LTE/CDMA.
Also, in the Status menu:
My phone number
Unknown
MIN
Unknown
PRL Version
Unknown
ICCID
Unknown
Seems a little odd to me.
Attempted fully rooting and flashing radios. No luck there either. It's also not wanting to update. Tells me my phone is up-to-date (connected via WiFi). Downloading Cyanogen now to see if it will work in the morning.

And while attempting to flash a new ROM, got the famous "can't copy anything to the device ever, under any circumstances" error.

Update: Got CM10 installed. Still "No SIM" error, no 3G, no data, no LTE. Found some more information on this No SIM error. Apparently a few others have had this same problem and in the end had to get a new phone.
Anyone know anything?

You should a- flash to stock using Odin following posts in sprint sextjon

I've been back to stock twice now. The first thing I did was flash to stock. Then I played around a bit and now I'm back to stock again.
Is there a difference between using Odin and Nexus Root Toolkit to return to stock?

Bump

Wow, one day and my thread is buried!
After battling for about a day, I got updated to JB 4.2.1, I can do profile and PRL updates again, but there is still no 3G/mobile data, and I still have zero bars on LTE/CDMA and have to use just CDMA. I am currently stock but the bootloader is unlocked, no root.
If anyone has heard any solution, please help. Also, if there's a difference between flashing to stock with Odin vs NRT, please say so.

Try fastboot flashing your LTE and CDMA radios again. As far as I know, fastboot commands do NOT require root. I had a similar issue.

Indeed, fastboot does not require root. I've flashed my radios several times now in various different ways. I even flashed different versions. I attempted again but with no luck. I have normal service when using CDMA but nothing on LTE/CDMA. Still no data, still "No SIM card" error.
Pretty sure I'll have to get it replaced. I've gone from stock JB back to stock ICS, rooted, CM10, back to stock ICS, rooted, back to stock JB unrooted, and flashed three different radios. I'm surprised I haven't managed to brick it yet.

UPDATE: Sprint is sending me a new phone, for free.

[Q] Sprint Note 2 LTE Issue

Hello there, I have been in the search for a perfect 4.4 ROM to work, I seem to be at an impass..
The 2 that I have tried, and Quite enjoyed so far are the Omni ROM and the Cyanogenmod 11
Both roms have the same issue, I cannot connect to a 4g LTE Sprint tower. I know the LTE Towers are working, My mom has the same phone, Sprint Note 2 and I have Mac's Rom on it and is picking up a very strong 4g Signal, yet my phone which sits literly right next to it, Refuses to get any 4g.. I drove around, went to known working areas, Never once did I snatch a 4g signal.
I played with the settings, it is set to LTE mode, I even tried Flashing as a fresh Install..
I tried flashing a Stock rom, but for some reason after it installs, and on boot up the phone does not work. I get a blank screen and literly nothing. I have to pull the battery to get it to turn back on. At that point I have to either Re-flash or restore a backup through CWM.
Any help would be appreciated, I miss my LTE Thanks

Same issue here. Not sprint though...

In cm11 set your mobile network type to cdma+lte/evdo or global. See if that works.
Next you can try to flash a touch wiz rom and do a hands free activation, verify lte works on the touch wiz rom, then flash to CM11 and see if you can connect to lte.

I have tried setting it to both. Global shows no signel what so ever on anything, I currently have it on cdma=lte/evdo and I just get a good 3g signal..
I might try that one out, Which is a good touch wiz rom to try and do that with ? I dont think I even tried a touch wiz rom yet

Personally I would recommend doing this:
Backup everything to your PC (both internal and external)
Delete the contents of the "0" folder on your internal card. If you use ES File Explorer, you'll need to enable root access, and then while in the app hit the menu button. The left menu will slide open and you'll see "Local".... underneath that you'll find the "0" folder. The problem is the way CM and Touchwiz mount the file system - they don't do it the same way. So when you do a factory reset in CWM, it doesn't clear out one of those folders. (I found this thread helpful - especially posts 2 & 4) I had major data problems on CM10 for 2-3 months, then I found this out.
After you do that go back to stock. Make sure you download the keep root file as well.
To play it safe, once stock, I highly recommend entering ##72786# in your dialer. The phone will grab the latest prl and update your profile. Whether or not you want to update the software (incl modem) is up to you, but I'd rather not get into the knox world.
Verify working gps. (I prefer "GPS Status")
Then go back to CM11.

I will try that out thanks

Update us on your progress.
If it works, consider hitting the thanks button - at the very least the guy in that other thread - I know I thanked him - his info saved me from going crazy!!!
I had working data (3g/LTE) on any touchwiz, but not on CM. It turned out that I had some corrupted data that wasn't getting deleted upon a factory reset. After I cleared out that data, everything was fine.
Hope your phone is back to normal!

Finally was able to download everything and run the tip, Thanks a lot dude! That helped and that did it ! I got 4g Back and everything is all peachy!!! Thanks again!

[Q] Data Connection Issues

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.
