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.
I've gotten my phone into a state where I see signal bars, I can make calls and send texts, but no LTE or H+ is displayed and if I try do anything involving the internet it says there's no network connection. Wifi works just fine.
Here's how I got into the predicament. I should have learned my lesson from last time I flashed a Verizon ROM, but I didn't, and I flashed SkyNote RC9Z-3.9.1. Data works just fine in THAT ROM, but any subsequent ROM flashed after that... the network data is completely HOSED. I've tried enabling and disabling network data in settings. I've tried flashing the Devil kernel. I've tried restoring several different ROMS from nandroid backups. All restore fine and all have completely non-working network data. Last time I ran into this I had to flash the stock image in Odin to fiz the issue. This time however, that didn't work. The images flashed successfully, but upon reboot all I got was a a welcome screen bootloop of the samsung swirly logo and the T-Mobile logo.
I'm guessing this has something to do with the 4.3 bootloader? I'm downloading T889UVUCMK7_T889TMBCMK7_TMB.zip from SamMobile site and boy is it taking FOREVER! 7 hours left on the download. My thinking thoug is that If I unzip this new 4.3 firmware and flash it with Odin (or Kies if I absolutle have to) my device will start behaving again, and Network data will work, and I can go about ROM flashing and hopping again (though I'm gonna stay away from those Verizon ROMs let met tell you!).
Does anyone else have any other suggestions on what I can do to get my data back or to patch my bootloader to the 4.3 version? I was looking at this thread and wondering if it's safe to follow this procedure for patching once I have installed the 4.3 stock image:

So about 6 months ago, I decided to finally try out some custom roms on my t999 after running stock for over a year. I tried a couple of roms and stuck with cm11. Every thing was great until about 3 weeks ago. Out of nowhere, my phone randomly decides to drop connection to tmo towers. Sometimes i have bars and 4g symbol and sometimes i don't have anything. When I pull the battery and restart, I am able to connect to data, make calls, and send messages for a few minutes, but then i lose everything. Randomly throughout the day, I will get signal back for a few minutes but thats it. I flashed a touchwiz rom for now so I can use wifi calling, So that still works.
So I tried to flash a different baseband modem from DocHoliday77 and none of them worked. I also tried going back to stock following DocHoliday77s guide once again, but for some reason that does not work. I launch odin3.07, put my stock firmware in the pda section, make sure only auto reboot and F reset time are checked. I connect my phone in download mode, it is detected and i start the process. The phone restarts but gets stuck at the samsung logo screen. I have tried flashing different roms and none work.
I dont think its an imei problem because I got the phone direct form tmo with a contract.
Does anyone know what I might be doing wrong? ANY help would be greatly appreciated.
Did you factory reset after you flashed the firmware in Odin? That's the only way it will boot coming from cm.. You may just need a new sim if flashing to stock won't fix it.. And BTW T-Mobile doesn't do contracts
I flashed the firmware for COI5 manually via odin and ever since then I cannot connect to LTE. Furthermore, I can barely connect to any signal. The bars show up, but it often takes a while for the 4G icon to show up. When it does, I am still not able to place a call, with Wi-Fi calling being the only hope I have to do so, but calls placed to me that way go straight to voicemail, so I have to call out from my phone.
Note: Knox is tripped, as I was rooted. I am also in an area where I alway get full bars of LTE, so location is not the issue.
Troubleshooting steps I have tried:
Reflashing COI5 firmware via odin.
Adding the LTE APN for T-Mobile.
Using Smart Switch to do emergency recovery.
Flashing BOH6 firmware (did not work as I don't believe you can downgrade firmware, was worth a shot anyways).
Flashing different custom ROMs (all repeated the same problem, which is how I narrowed it down to having to do with the firmware).
I am currently running completely stock at the moment. If anybody has any suggestions on what I should try next or how I can fix this, I would greatly appreciate it.
I picked up a Sprint prepaid HTC 816 recently and decided to flash this rom below
[ROM][UNOFFICIAL][CM12.1][5.1.1][VirginMobileUS][A5][single sim][1/1/2016 security]
That one
It installed great, had everything everything working after I added my Sprint APN settings. The phone still displayed it as Virgin Mobile and only 3g seemed to be working. But I was making and receiving calls, text messages and had mobile data.
Fast forward a couple of hours, I installed a custom theme from the Play store, rebooted and ever since then I lost the ability to pickup a network signal and access my APN settings.
If I re-seat the sim and toggle airplane mode it will pickup a network signal and I can regain apn setting access again but it drops within minutes.
Ive reflashed the rom, wiped everything reflashed again, same thing. Any ideas on what has happened?
Thanks and appreciate your time!

Are these the APN codes you used(poster corrected a mistake in green text)? Looks like there is a different APN for prepaid /postpaid.
http://androidforums.com/threads/working-sprint-prepaid-apn-settings.920752/
I indeed use the apn settings in the green from that post. They were working fine until I had a reboot. Then everything went to ****. It wont even let me access the apn settings and when I can its briefly and then I lose signal and apn access.

I had an issue with something on my Virgin mobile 816 a5_chl a while back and a member @wxppro was very knowledgeable about APN settings and their intricacies. He had a MVNO 816 at the time with an APN issue and I bet he could help you with this as that was my best suggestion for a fix and it didn't help you.
See if you can direct him here to this forum so that if he can help out the info is here to help others as well. Good luck.
Not sure how much I can help. APN is a tricky business. If your APN settings disappear after some time, it is generally because the cellular network the phone connects to does not match the APN's MCC/MNC numbers. Or it could be the phone is in 3G mode (CDMA EvDo mode).
You can try these things:
Switch network types, from LTE to 3G, wait a minute, and then back to LTE. APNs do not show up in 3G mode. They only show up in LTE (or global) mode.
When you have the APNs show up, check the parameters are correct, you can do a "Restore to default" and then add the new one following that post.
Hope this helps.
I'm having a similar issue as well (except on virgin mobile)
A month ago I flashed squid's version of CM 13 on my phone and everything was fine for a few days, until I completely lost LTE and access to APNs. I reverted to stock and still was unable to get LTE, although I could get a shaky 3g connection if I changed the network mode to CDMA only. I called virgin mobile and they walked me through the troubleshooting steps and eventually determined it was a network outage (even though two desires in my house belonging to other family members had LTE). I called again after they verified that the network was working again and they were still unable to fix the issue.
Recently, a friend upgraded from a desire to a different phone on a different network, and gave me his old phone. I plugged in my sim card and activated this new phone and I got LTE. Figuring everything was good, I decided to flash squid's ROM once again. The same issue happened, I got LTE for a day or two until it cut out service again. No access to APNs, not even any service in stock or on the official build of CM12 with the APN fix (I can't access APNs there either). I'm out of ideas and would appreciate if anyone had any input on my issues.

I have this same phone a5_chl Virgin Mobile. Did you factory reset your device before flashing back to your stock rom? The other thing is and this is just my opinion not a statement of fact or a knock on the wonderful Bigsupersquid but that 13 CM ROM is nowhere close to being stable enough for me to risk flashing it to my daily driver phone. Just read all the posts and his candid responses. You were basically a beta tester .
I'm not an expert in APN's but if you can't get that fixed your last resort might have to be wiping your system and then flashing or running the executable RUU (rom utility upgrade) file found for our device on HTC/downloads . This is a last resort option and wiping your system will remove your existing firmware so have the correct RUU for your phone downloaded to your computer before attempting a wipe. If it's an exe, which I believe the U.S. Virgin Mobile one is ,you will hook up your phone fully charged in fastboot mode then from your computer run the exe RUU like any other exe executable program and wait. It will reformat all partitions and reinstall pure stock ROM. Hope someone else had an easier fix for your data issues and good luck.
EDIT: you will need your stock recovery flashed back and a relocked bootloader before flashing the RUU but I've read that some have flashed their RUU over a custom recovery with a locked bootloader and it wrote over the custom recovery with the stock recovery. I have never personally tried this just the first way I mentioned and that worked for me.

I did try factory resetting and I am on stock after flashing the RUU. It makes no sense as the RUU should have reset everything. That perplexes me the most

OK then you did get back to stock not from a nandroid backup but from flashing or running exe stock RUU? If that's the case then it replaced everything that might have been changed and your issues shouldn't be related to any APN changes. You also removed and reinserted your sim card as I believe, correct?

i posted about my lte issues i had for nearly two weeks, running stock just to verify the data service problem wasn't my rom...
i had to install stock recovery, relock bootloader, download the ruu.exe from htc and extract the .img file in Wine, then rename it onto the sdcard and reboot into hboot so it'd flash. neither Wine nor virtualbox xp talk correctly to any of my phones over usb. and i wasn't about to native install Windoze.
factory reset stock didn't fix it, even trying activation, update profile, etc.
i learned i could get 3g data but switching to lte instead of cdma shut down data entirely.
virgin eventually directly escalated me to tier 2 tech support in my last call, they sent a couple service programming pushes to the phone that got my lte back online.
i tried the various service programming menu options repeatedly, with no results but the prl updated once; but the trigger to fix my lte seemed to come from upstream.
i tried various apns, in cm12, cm13, and stock lollipop. rebuilt init_a5.cpp with different mccmnc and adjusted apns. i really tried most tricks in the book plus a few more.
as far as alpha testing goes, at this point I'm just sharing something cool... i always enjoyed flashing latest greatest on my ov way before i was building.
not too many actual logs to really bug report for either rom.

Some of that was over my head but happily not all of it. Basically what your saying is the fix needs to come from the carrier and it's a reset issue on their end not a custom rom issue? By the way I'm a big fan of your work. Hell I might be on one of your older ROMs right now I've flashed so many I forget. Thanks for the education.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

This is starting to scare me as well because I'm thinking of going back to stock once Marshmallow gets pushed to our phone to get my beats drivers back and this is making me think twice. Sorry your having so much trouble.

seemed that way.
i took radio logs before and after it worked, and worked only on 3g, and it looked to me like the sim card responded differently to the ril after things were running right again.
mine might've been a special case, though, it came from ebay with no sim, and virgin had to go to a little effort to get it programmed when i installed the sim initially.
they also claimed for several days that the local Sprint tower was down for lte service.

tier 2 takes luck, time, many calls, and eventually you learn the answers to all the questions tier 1 outsourced from India asks so you can feed it to them so fast they want to shuffle you along. takes a couple of weeks to over a month to get to tier 2 and sometimes they have to be involved multiple times as well.
I've been dealing with virgin since 2009... replaced only two phones, eventually got the rest of the issues hammered out with persistence.
for a little while, twice, i had direct toll free numbers to American tier two even because my issues were so hard to solve. it didn't take too long for those numbers to be disconnected, though.
