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?

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.
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.

There are some other options in there for networks (e.g. TD-SCDMA, CDMA auto). Would any of them help picking up Sprint LTE?
Other options include:

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.

Worked like a charm thanks a lot!!!!!
Same issue with hotspot using super g2 rom.
I tried updating PRL but my data still goes on and OFF. Is there another hotspot mod I can use with this rom? Any help would be appreciated.
As a bump to this thread, and to keep the forums tidy, I, too, am having issues with SuperG2
I flashed it and it worked beautifully but I was unable to get any data service. I tried updating PRL/Profile but that would not work. Kept giving me a network error.
That being said, I finally got data to work (beyond me, not sure how this happened but I did NOT get PRL/Profile to update) and was using it merrily until I began to restore some files I had backed up via Titanium.
I rebooted to get the data from these files to run smoothly but after a reboot I lost all connection. It told me that my service was disabled.
I reflashed the ROM but am back to square one - unable to updated my PRL/Profile and cannot get any data, even tho the LTE logo is at the top and spinning. WiFi tethering works and I can access the internet in this way, but not in any other way.
I am being forced to go back to stock =(
Any help would be appreciated.

Connect to wifi then update the profile and prl (can be done at home if you have wifi, or mcdonalds, or starbuck, or anywhere that has open wifi)
Similar Issue
Running SuperG2, comming from Milestone1. I cannot seem to get the WiFi tether to work on SuperG2. It worked great on Milestone1. I tried the update PRL while Wifi tether is active but to no avail. I'm not sure if it's related but my signal kinda sucks too. Where I normally get 4g now I only get 3g with sparatic 4g and I also loose my signal altogether at times. I have to activate airplane mode and then deactivate it to get my signal back. I would go back to Milestone1 but SuperG2 is the frontline. Need to keep moving forward. Any help is appreciated. Thanks.
Was on nf1 and experienced lte data dropping out of nowhere. It happened once everyday, sometimes more than that. After a toggling data on and off it would work again.
I updated to NF4 and problems have continued. Anybody else having this issue?

No.
I do see that when the phone transitions between 4G and LTE or vice versa, I loose data for a few seconds. But that is rare.
I've been experiencing this forever. Seems like no one else is though. Only thing I can do is toggle airplane mode on and off and deal with it...

If you can still use data than no. Data dropping is when it completely cuts out.
I have an N900t on T-Mobile but was experiencing the same random signal loss/no data issue as the OP after the 4.4.2 OTA and updating the baseband to NF4. Afterwords I rooted using the (CF-Auto-Root) for NF4 method and installed the Effortless 4.4.2 stock based ROM. Had the same signal issues so I went back to stock NF4. I immediately got notification for update to baseband NF9. Did the update and so far so good on the sudden random dropped signal issues. Now trying to figure out if the Rooting NF4 (CF-Auto-Root) still applys to rooting the phone after the NF9 update.

Yes, I'm having the same issue. Usually turning on airplane mode then turning it back off fixes it. I updated to nf4 a few days ago and still have the issue. Stock t-mobile rom, not rooted, service with t-mobile.

I'm nf4 and updating stopped the data drops on lte but on switching to 4g data takes about a minute to respond, on NB4 lte would become unresponsive. ..so that seems fixed for me on nf4.......i did a full wipe including internal sdcard and everything has been working fine except the handoff to 4g. Don't know if it helped but i took out sim during the whole process. Ran stock nf4 firmware with pc odin, then rooted and replaced custom recovery then booted to recovery wiped everything except External Sd then rebooted the recovery back into the recovery then flashed the rom I'm currently running.
In your case since your mostly stock I'd get the pc odin tar, remove the sim, then run odin and select the "update bootloader" switch (or something like that) and run it and then boot into the rom (still without sim) setup phone then power down and pop sim in and try the features again that you've had problems with.
(^^^just a suggestion, maybe someone else has a fix)
Also backup your internal sdcard prior just to be safe.

Wifi works. Data/Calls do not.
What do I need to update?

You probably have to update your bootloader, I had the same problem a while back. I Oden the entire 4.4.4 tmobile firmware and haven't had a problem since.

Well If you really need your phone to work properly, receive and make calls, working mms and have long battery life and not blow up, you may have to settle for stock /touchwiz.
