3G sometimes doesnt turn on after call or no wifi - Samsung Galaxy Nexus

My wife has the CDMA Galaxy Nexus and I unlocked her bootloader and temp booted CWM and flashed stock 4.0.4. I did the same to my phone but have since rooted and installed a custom ROM. Anyways... there have been several times where after a phone call or not being in range of wifi when the phone is trying to switch to 3G but it's just grey for a long time and never turns on. I then usually put airplane mode on then off for it to connect and it will after that. The fact that this has happened several times is really annoying. Has anyone seen this issue before? I was just thinkng of rooting her phone and puting a custom ROM on but before I do, I wanted to check with this forum first.

did you flash the 4.0.4 radio? if not, try that.

Is the radio actually off, or is it just getting no signal? Either some app is causing it, or it may be the radio hardware going out. Have you tried using the latest radio firmware and doing a prl update *228 option 2 (us only)?

Thanks for your comments. The problem if a permanent failure. When receive any call or sms, the radio is turn off with no notification. Will test making a factory reset. Look like a software failure which started 3 weeks ago. HTC phones update via OTA and maybe downloaded and installed a corrupted file.

[Q] TMO SGH-T989 wifi not working. is this h/w issue?

I bought this phone used from eBay and it worked fine for about a month.
Then the Wi-Fi stopped working. as you can see in the pictures, the wifi button (slider) is disabled/grayed out and if you go into the menu, it is stuck on "Turning wi-fi on".
I've tried everything from downgrading to 2.3.6 GB (currently on official ICS 4.0.4 through Kies) to installing Cyanogen mod ROM but it wont work. rooted then unrooted. everything else works great.
Any help would be appreciated.
I've attached screen shots to this post.
Thanks.
Did you powercycle modem and then router?

Yup. I did. I have other devices on home wifi that have no problems connecting. In addition i have tried at starbucks and work wifi. Still no go.
The WiFi on the Galaxy S2 wont even turn on to recognize/select networks (SSIDs) to connect to. As you can see in the pics, the Wifi ON/OFF button is grayed out/disabled.
Did you try flashing a different radio since the issue started? If not I would try it, maybe downgrade the radio to UVLI1 or even try re-flashing the same radio. I know I had this issue once before but fixed it somehow, I think it was just a reboot for me but if you tried all of what you said in the OP you would have rebooted a few times.
Did you use Odin to flash back to stock? If not, give it a try with a full wipe.
Although i have not tried to mess with Radio (noob here, not sure i wont mess that up), I did Odin the phone back to stock ROM with no luck.

When you flash a stock rom in Odin, it also flashes the radio.

Ah Ok. There you go then. and i tried with a couple of TMO stock ROMS (starting with GB 2.3.6). so obviously that hasnt worked. Thanks.
i found a possible fix, that worked for me. Go into your recovery, i did it with TWRP (latest one) and advanced and fix permissions, than i rebooted and worked! Give it a try.

To avoid any future hassles I contacted the seller and he agreed to take it back for a full refund, so i guess i'll never know what happened. Thanks for your help everyone.
I know this thread is nearly a year old, but I had this problem and figured out a fix that worked for me so I know its still relevant.
My fix was:
- reboot into latest cwm recovery (v6.0.4.3 touch for me)
- click "mounts and storage"
-click "unmount /cache"
-reboot
So far it has worked every time and wifi screw ups have happened rarely ever since. Hope this late post helps at least one person who was as frustrated as me!

My WIFI is off, and if I hit turn on, it got stuck on turn on. But if I were to back out and go back in, it would be on off again.
I'm using Kitkat
After awhile all i had to do to fix it was turn airplane mode on and off. But just the other day, I was flying so had my phone in airplane mode and now that won't fix it and neither will my original fix :crying:
I have the same problem
It was working fine stopped and did everything and still not working,

[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.
Edit: link to post with directions http://forum.xda-developers.com/showthread.php?p=39446679

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.

no signal after flashing rom

i have a samsung galaxy s3, ive been rooted for a long time and flashing roms all the time. well i flashed a rom just now and i have no signal, not sure if i burned out the radio (not sure if thats possible, but it also said to insert sim card while it was already inserted), but i dont understand how that would happen. the sim card works in another phone that im using now, so its not the sim card thats causing the issue. my carrier is at&t, and no signal showing, not data or cell (wifi still works, but thats a different story). has anyone experienced this and know how to fix it? im guessing modem flashing, but not entirely sure. can someone please point me in the right direction? Thanks in advance!

I believe you need to do a factory reset. Backup your data first!
Sent from my SGH-T999 using XDA Premium 4 mobile app
The first thing to troubleshoot you should do is flash back to a rooted stock rom and make sure the data is working there. If so this will rule out any sort of hardware problem. You didn't say whether or not you did but you can also try fully wiping the phone (dalvik/cache, system, and data), re-download the rom incase you had a bad one the first time and reflash. Other than that check that maybe check the apn settings.
Yup I ended up doing that last night..im back on the stock root injected rom. So im still rooted and network now works! So im glad. How would I flash a rom without losing the network this time?

Now that you have flashed back to stock a full wipe has been done in the process. At this point all you can do is flash it and see, but as i said i would redownload if you plan on using whatever rom it was you mentioned in the OP. I would also do a full nandroid backup to save the pain of using odin incase it doesn't work. I imagine the problem was with lingering files/fragments from multiple flashes that were causing the problem, in any case whatever the problem happened to be it was software related.
K will do. Its just weird because the md5 matched and everything..but I will for sure download the rom and gapps again. Thanks for the tips!

well, i finally got the service to work after flashing a rom. it still remains a mystery to me tho, i used to always use the illusion rom everyday, for months. i decide to flash the same exact one but no service, i download it a couple more times and still no service after flashing about 3 or 4 times. i tried a completely different rom and the service is active. i dont understand why and cant figure out what is so different this time hah. o well, im just glad its all working now even though its with a different rom. thanks for the help guys!
ok, im back =[
i was using the carbon rom with no problems, it was working great, but just a half hour ago i was listening to music and texting (i always do this), and then phone just turned off. I tried to reboot it but it wont! it always shuts off while booting. i made it to CWM, but it turns off while in CWM. i also made it to download mode, which led me to assume that the phone is not bricked, but it doesnt stay on download mode, it just turns off randomly. i figured maybe it was battery, so i tried another, and no change! does anyone know what the issue is? i cant figure out how to keep the phone ON, or why its not staying on.
btw, i got it to boot completely just once, and it was acting up still. any ideas? please help
Thanks in advance

What is the bootloader and baseband version on the phone? Which version of stock are you flashing?

4G won't stay connected

I've tried all sorts of roms, AOSP and Sense, they all stay connected to 4g for a few minutes at most after a reboot and then go back to 3g.
Everything else works fine, and my sim works good in other phones and stays on 4G.
Any idea what this could be or what is causing this?
Have you updated to the latest firmware? If your using kitkat roms, you need kitkat firmware. You can find the firmware in the second post of santods stock rom thread in development. Use the no boot.img one.

Yea I've flashed those also. Everything used to work fine until that roaming display issue. Never returned to normal for me, even tho roaming is gone.
Have you ever ruu'd back to stock and then done a factory reset from hboot? That is the only way to wipe out the network settings and force them to be updated. Worth a try i guess.

I'm not getting 4g at all on my phone. I came here to post a question and saw yours, so thought posting another thread would be pointless.
I've got NusenseSIX RC4.5 running and while the 4g icon comes on, there's no data transfer at all. I flashed the new firmware first, as instructed, and that seemed to go just fine according to the directions. But, when I swapped my sim card from my other One and waited a few minutes, even *228'ed, no data.
I got the phone already rooted and s-offed with TWRP 2.7.0.1. How do I get it back to stock to clear out the network settings? Or could it be a bad firmwware flash, so I'm screwed anyway?
EDIT: I redid everything, and just stuck with the Sense 5.5 mostly stock ROM. Data works now. Might've been firmware, might've been the ROM on my phone. Zero idea.
Is it possible to have a bad sim?
I just got a replacement device and I still cannot get 4G service for more than about 2 minutes before it switches to 3G

Sure, you can have a bad SIM, but I don't think that'd cause the drop in data transfer rate... lack of data all together, or other things not working, sure, but if you can actually catch a 4G link and then it drops to 3G, sounds more like the radios, the hardware, or just a bad coverage area. I'm no expert, though.
In case anyone was wondering, I ended up getting a new SIM and that has fixed my 4G issue. No idea what was wrong with the SIM, but anyway it sucked.
