LOS Workaround

Found this workaround to a problem many users are having with LOS then not reacquiring. Simply put the phone in airplane mode, open the task manager (long press home), go to RAM and clear the memory, take the phone out of airplane mode and it should now be good to go. This or reboots will have to do until a fix is released
Just airplane doesn't fix the issue and rebooting is a drag since apps and everything need to be restarted.

I had this issue since day one of flashing Max's kernel so after a week and a couple kernel changes and even a flash to StarBurt ROM i finally got my phone to stay connected.
I flashed back to stock kernel. After resetting I pulled the battery for about a half minute then once it connected again I did the ##72786# and reset the phone again. Make sure you have your MSL number for that. Once I had connection I then updated the profile. rebooted After it reset I found I still have root, still have Starburt ROM and have stock kernel and no more LOS on either Wifi or network. For a week I couldnt keep a signal on either one and it was frustrating trying to use the phone to upload or use Nav. Its been about 4 hours now and I have yet to loose anything so maybe this can help someone else who is in the same boat.

Could you confirm that this is still working?

Ive had it running for about 8 hrs now and havent had a loss of signal on Wifi or 3G. When I was having issues with Wifi, the wifi signal would only be 1 or 2 bars. Now I have all bars in WiFi and no issues as of yet. Using 3g has been good to but in my area I usually only get 3 bars so so far so good.

I had the los just after I flashed max's kernel too but flashed the stock kernel and then rooted, then updated the profile and rebooted. So far no los for two days

[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] No 3G data connection!

So, here's my situation:
I'm running a CDMA Gnex with Apex v.1.0.1 as my rom. I flashed a new radio, [Radio Hybrid] VZW EK5 CDMA(4.0.2) / EK4 LTE(4.0.3), in the hopes I could improve the hand off between 3G and 4G... Nope! The phone will no longer, no matter what I do, connect to the 3G network
OK... I figure, no big deal. I'll just flash a different radio set. Next up were the Leaked 4.0.3 Radios. Same thing. NO 3G at all!
Now I'm getting worried. I flash the stock 4.0.2 radios... Still cannot force it to use the CDMA network. I either have 4G data service or none at all...
What am I doing wrong? I've re-booted each radio set a couple times before dumping them for a different set. I've restored the nandroid back up from before I started messing with the radios. No fix there either. I've removed the sim card and reinstalled it (knowing full well it only controls 4G). Nothing doing...
I've seen similar posts about 3G/4G connectivity issues, but mine is strange because it's just the 3G radio that doesn't work. Voice calls and 4G data work fine.
Bigxie's rom has been rock solid, and since all the radios I've used presented the same issue, I'd be hard pressed to say it was one of them. I'm a noob, so I'm thinking user error somewhere along the line. Any help would be appreciated.
Update:
This was a CDMA network issue, not an issue with the Radios or Rom!!!
I magically picked up 3G this morning while at work. Since I was still running the leaked 4.0.3 radios and the Apex Rom, I realized that this was a network problem, not a software problem. I confirmed this with Verizon just now. They brought down the node closest to my place for emergency repair last night. The CDMA radio came back up as soon as it hit a tower that let it authenticate... It was just a coincidence that it occurred right when I flashed my first radio set, and frankly I feel dumb that I didn't see network error as a possibility sooner.

Try going all the way back to stock with stock radios and see if that fixes it?

flash the bootloader before the radio, reboot after flashing the
bootloader then flash radio, reboot, then flash stock.

Captivate Glide - JellyBean 4.1.2 SIGNAL Problems

Hello everyone, I've seen some other threads about similar signal loss issues or problems on the i927 around xda, but none of them worked or were compatible with the type of problem I'm having. I recently installed the January 6, 2013 build of Paranoid Android v2.+ on my i927, and it works great. However, I've been having one major issue that renders my phone useless. After about an hour or so of having the phone on, I lose ALL signal to my cell network (AT&T). There are no signal bars, no messages/MMS/calls can be made or sent, and I end up having to reboot my phone for it to function properly again for another hour or two.
I've tried what some users around xda have suggested such as taping my SIM card in place or wiping cache/dalvik cache in recovery, but as of yet nothing has worked
If anyone can help me, it would be GREATLY appreciated. I'm stumped at this point after exhausting all the options I thought would work. I really want to keep this ROM on my phone, it works better than stock or any other ROM I've tried yet by far.
Thanks in advance!

ALSO, I can post screenshots or any additional information if it's helpful in any way.

How did you unlock? I've had problems with signal when I unlocked via galaxsim unlock tool. Check your /efs/Nv.log for errors, I had an error connected with md5 sum every second or so.
For me, the other unlock way solved all the problems.

can you see in about, your imei, maybe is corrupt. see this link, maybe help http://forum.xda-developers.com/showthread.php?t=2019540

I haven't unlocked my phone, it was sold to me as an AT&T phone. I don't think my IMEI should be the problem

I also experienced this issue on 4.1.2, so I moved to 4.2.1 hoping to avoid it, yet this morning issue happened again with thegreatergood's i927 - CM10.1 - 1/22/2013. My IMEI is ok, unlocked by entering the unlock code given to me by ATT.
Note I am able to restore connection by switching on and off airplane mode, might save the time of reboot.

Yeah, I've tried every now and then to reset my connection by toggling airplane mode on/off, and it usually works for me too. I'm just stumped on why there's an issue with the signal at all to begin with, it doesn't make sense to me

I confirm, I also experience connection lost from time to time. And I also restore it with switching airplane mod on/off.

The same problem with 4.2.1
Hi! I had the same problem with the phone. The signal was totally off. I was using LiquidSmoth 4.2.1. I gave a solution flashing the rom another time.

I've seen this on AT&T's ICS firmware, it gave me this issue often and for me a reboot was the only fix.
I've upgraded to CM 10.1 and I am hoping it fixed the problem. If not, I will try flipping airplane mode off and on, I don't like battery out reboots, but if it doesn't any more suggestions welcome.
Thanks.

I've been using cm10.1 for months now & haven't had any issue with signal dropping. Did have if happen with other roms, but I think it's something to do with the kernel more than the rom. They just released rc1 of cm10.1 has the latest kickass kernel.

[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.
