My wife and i got our GNex phones at the same time in April through the Amazon wireless store. Both of our phones had to be repalced by amazon within the 30 day window for 4g/3g/1x signal drop issue. 4g radio would just totally crap out, then would wipe out the 3g and then i would have a complete signal loss. Everything was fine after we got the replacement phones. My wifes phone is totally stock and has had zero issues. Mine is rooted running AOKP toro IMM761, Android 4.04. 4 days ago it started having the rampant 4g signal crash issue again. I've turned off the 4g radio for now, but according to NoSignalAlert, with just the 3g radio on i've had complete signal loss 7 times today. I'm in the same area as usual, my house and my office where i normally have 2+ bars of 4g. I'm thinking the radio has gone bad in this phone, like it did in both of our previous GNex phones, it just took this one 6 months to die. Now i have to deal with Verizon Wireless to get a replacement. They are wanting to make sure i'm on the most current build, baseband etc. Here are my questions.
1 - What is the most current stock ROM, radio, build etc. that i an put back on my phone to both a)make sure that a rooted app/baseband etc. is not all of a sudden causing this issue and b) i can talk to VZW and they won't know i've rooted the phone.
2 - Once i return the phone to a stock ROM, i assume that I will have to do an OTA to satisfy the VZW tech. If the phone does not need to be replaced, i.e. the OTA fixes it, will i still be able to root back to an AOKP ROM?
3 - Is there some other update i should try before going the "unrooted" route and trying to talk with Verizon?
Thanks for your help.

Here are the VZW radios for the Gnex. Personally I would try flashing the new one [4.1.1 (JRO03O)] with a JB ROM. I was on AOKP for pretty much the entire life of my Gnex, 8 months, and never tried CM10. Flashed CM and besides the Nav bar, which I like better in AOKP, I have seen substantial improvements in performance, stability, and even better battery life. If you are determined to stay with AOKP I would still update to the JB version and try those "new" radios.
I started having the same problem a couple days ago when flashing a ROM went bad so I had to restore to an old (4+ mo. old) backup. From there I flashed factoryrom jb and then flashed the new radios today Cuz I just noticed the lack of signal. Still no bars anywhere. Any other thoughts? Do you think flashing a CM would fix it? If so, why?

What is selected in settings-more-mobile network-network mode?
data enabled is checked, and network mode is LTE/CDMA
I was gonna try to find a fix today and if i can't find one, flash to complete stock, reroot/mod etc.

Well, your settings are good to go. Did you check the md5 sum of the radio file after you downloaded it? If you have root explorer hold down on the .zip file and choose properties to check the sum and make sure it matches.
hahaha i guess that's what I get for trying to download a radio on crappy mall WiFi... the MD5 was bad :-/ works good now! thanks!

Hmm, it did this "need to restart SIM to work properly" crap, restarted and stopped working. Any thoughts? I'm installing franco kernel to see if that helps
Welp I ended up just flashing the factory image hahaha, will reinstall ROM and see how it goes. Everything seems to be working fine right now though
Glad it was something simple like that to get you back up and running.:good::highfive:

I d/l the 4.1.1 radio and flashed it in clockwork, and though the flash said it completed successfully, i don't see a way to check the radio version. I don't see 4.1.1 JR03O listed anywhere in the About Phone information...Where should i be looking?
Further, my prboblem seems to have further degaded ...With the 4g radio on, i get random total shut down of the phone, as opposed to simple radio crashes. Just goes to off with black screen. I'm up to try anything. I assume i can easily locate one of these JB ROM's in the dev section?

The baseband i think. Mine is I515.09 V.FF02 / I515.FG02.
I'm not all that knowledgable about the radios I just know my reception/data was poor on JB ROM with ICS radios. When I flashed the JB radio, my issues were fixed. I believe the ROM and radio versions should match, so if you flash JB radio I would flash JB ROM. All the info should be in the thread that is linked.

I am such an idiot, this whole time you've been talking about JB ROMs i assumed you meant some particular brand of ROM, like AOKP or Myn etc... It didn't dawn on me until i saw JB next to ICS that you meant Jelly Bean ROM.
Ok i'm running an AOKP Jelly Bean ROM with Android 4.1.2
baseband is the same as yours
Build is aokp_toro-userdebug 4.1.2 JZo54K
The radio problem seems to be resolved. Thanks for the point in the right direction!
oops, accidentally wiped my sd card when i was restoring back to factory... TOTAL back to factory hahaha.... which isn't so bad i guess... after a year it's about time I guess
I seem to lose signal when leaving wifi though, have to either airplane mode or reboot. Because I had my phone so long, I don't know if there was connection or dust issues, so I did the classic NES/SNES/Sega Gen trick, took the sim card out, blew in there and all that. Seems to still be going ok.
Fyi.. i a simple restart doesnt disconnect u from the towers.. u need to turn off, pull battery, pull sim, and wait for 10 20 sec. That will disconnect u fully..

Just flashed to a new rom yesterday and now my phone is completely incapable of getting a signal.
I've flashed plenty of roms and they've all worked fine until flashing to a 21889 rom yesterday (firestormLeo v5.5). Not a single bar of service since. Text messages don't get received and no data either.
I reflashed, hard reset after the flash, updated the radio, flashed back to an older rom that worked, and hard reset again.
Nothing works! I now have a completely unusable phone (phone-wise). It completely works otherwise (music, sync to pc, wifi etc) although it does seem to get warmer than usual. I'm assuming that's because it's trying to grab a signal or something.
Anyone have any ideas on whats going on?
I would try flashing the original rom/radio that came with your device including removing the spl and seeing if that fixes it.
If that doesn't fix it, then you are all prepared for warranty service.
If it does fix it, then you can reflash your favourite rom and it should still work. But sometimes flashing an official rom can fix things. I know back with my Kaiser it was advised to always flash an official rom between switching from an unofficial to another unofficial.
thanks for the suggestion!
just did all that and now i'm on stock rom and removed spl but it still has zero signal/service.
i bought this tmo tp2 from craigslist so i'm not sure if i'm covered by warranty. where do i go to get this fixed? or am i screwed
anyone else have any idea whats going on?
I had a similar problem with you(http://forum.xda-developers.com/showthread.php?t=616426), and have been waiting for some reply since last night, though got none, but the problem disappeared on it's own.
I continuesly flashed and flashed official ROM's and Radio's, totally gave up at the end, charged the battery to 100%, removed battery and let it like that for 5 hours, did an hard reset, and well, working as well as new.
It's a T-Mobile version as well, though my problem was losing signal continuosly and asking for PIN again and again every 5-10 mins. HTC support offered me to use another SIM card today, since I asked what could I try last night, though I didn't have the need for it =)
A lot of roms do not come with a radio so you may have to get one and flash it. If you put stock rom back on make sure it has a radio as well. Make sure the radio matches the rom and the ril.dll is the right one.
I have not had the problem but have read about others flashing new roms and no signal only to find out they had to write a radio as well.
i'm certain i have the radio flashed on it and it isnt the problem.
just took the battery out and hoping it'll somehow fix itself in a few hours.
I would also recommend to flash the shipped stock rom. Go to htc's support/download page and download the rom they have for the t-mobile touch pro 2.
If that doesn't work, take it in for warranty with t-mobile. I purchased a used at&t tilt off craigslist and had an issue with it. Took it into at&t's device support center and they replaced it no questions asked.
whenever I load a cm10 based rom my wifi drops after 2 minutes. stock based wifi is consistent but as soon as I load cm10, jelly ro, or even the new experimental m1 build with always drops. to reconnect I have to turn off and on wifi. is there any solution? I was reading about cm10 modems and I didn't install anything besides cm10, aosp jelly camera and jelly gapps. any help will be greatly appreciated!
ps just realized I install the camera on every build could that mess it up lol
I've been running several nightlies over the last few weeks and now I'm solid with the M1 build and at this point I have never experienced an issue with wifi dropping.
What steps did you take to flash CM10? (cache clearing? Full wipe? Permissions?)

I did everything except permissions. Are there permissions for wifi?
No I was just mentioning the common steps so you would tell us everything. Sounds like you've installed the rom correctly but obviously their's an issue. I'm assuming that this issue is right after a clean install and not after you've installed juice defender or something like that? Assuming you're installing the correct version of CM10 for your phone (d2att?) their shouldn't be anything else needed to make wifi work (ie modem file).
If I were you I'd be tempted to redownload CM10 m1 and jellybean Google apps. Ensure you have the recommended version of cwm installed. Clear caches, full wipe, flash CM10 and apps followed by clearing of the caches again. Forget the camera initially and test the wifi. If it still doesn't work we'd need to start looking at logs.

Hey, I was hoping someone else would chime in about the logs. I have used "alogcat" for logs before but I'm not familiar with wifi filters so I'm probably not the best person to help at this point.
Anyone?
Ian
Running the new cm10 15th build wifi is more stable but still drops after about 10 minutes. Any help would be very kind.
With all your flashing and even using latest versions I'd start to wonder if something to do with the rom is not compatible with you're rougher. Have a you tested it on an alternate wifi source? Maybe a neighbors open signal or something. It's a noob thought but it couldn't hurt.

Yes I have. Currently on a different network right now and it was still dropping. Less frequently but still happening.
I've been trying to get alogcat working on my phone but the log is blank no matter what I do. Either way, the main developer thread just got a post about wifi and how it's note staying connected. No responses yet but it would become a good place to follow as that's where the CM brains are. If I can make some sense offer this log business ill get back to you without some more ideas.

Same problem here with wifi on Galaxy Note n7000. It started since I moved from CM9 to CM10.. Now trying every new Nightly, but with no success. Still losing wifi spot every 1min - 10minutes.
Thought if I download something, then wifi is stable, but soon after download is finished, wifi connection is dropped.
Working for me ...

I have a Rogers S3, and am currently running CM10 NIGHTLY 20120924. Everything appears to be working well, including Wifi; however, there is the occasional (and I mean quite rare) glitch where Wifi does seem to have a bit of difficulty connecting. Again, this is extremely rare on my device, and it may simply be something unrelated to the ROM.
Peter
YES!! This has occurred for me on the stock ATT TW rom and then same thing happened on EVERY OTHER ROM I tried after that including AOKP, LiquidRom, Aristodemos....
It's annoying and I don't know what to do.
The wifi will connect and stay blue for 5 seconds then turn grey for 10 more sec and then wifi will completely disconnect and wont reconnect unless i turn wifi off and then on again. im at a complete LOSS.
anyone have any ideas?
Exchange it. Don't put it off just use titanium backup and switch your phone.
I am having issues with WiFi on CM10 also. I can use the internet like always but the signal bars will go gray sometimes then back to blue. While they are gray I can browse, usually with chrome, but youtube will not work. It is odd that some apps won't work but some will. It may be dropping and coming back but is not strong enough to stream video.
I am using CM10 10/9/12 nightly and an N600 Netgear router. I am starting to think the Netgear router might be my culprit. I have always had dropout issues with them in the past, although, my computers, 360, and PS3 have no issues. Maybe I could just make it a signal repeater and get a Linksys again.
Has anyone else had this issue, think it is the Netgear? Should I try a new router firmware like dd wrt?

I was running latest paranoid android and I wiped cache/dalvic cache after flashing Cerberus in recovery and when the phone booted up it was asking me to Activate (sprint service) my phone. I've never seen this with flashing roms and was wondering if this is a known issue with flashing roms on the S3 or something that can randomly occur from time to time.
Anyone have experience with this before? I had been running Paranoid Android for less than 24 hours but initially didn't have any problems whatsoever.
Itll do that sometimes depending on the rom. Usually does it after a factory reset and installing a cm based rom. Its just asking you to add your google account... you should be fine

This didn't have anything to do with my Google account. I guess I should have been more specific, I mean that my phone is deactivated on Sprint's network as in I can't make phone calls and all the info is missing in about phone. Phone number, PRL and such. I am flashing back to stock right now and hope this fixes it. Will probably give paranoid another go but this doesn't sound like a common issue because I haven't been able to find anything by searching.
When you get back to stock it'll probably reactivate itself. If not (although you can do this regardless just in case), ##72786# in the dialer should set you straight. If I'm not mistaken the screen you're referring to should be gone when you boot stock regardless. Its a bug. Doesn't work for a sprint phone but still buried in the rom
Ahhh... could try manually flashing your modem after the install too

Soon as I flashed the stock rom it tried to activate and initially failed and prompted me to reboot. Second attempt it was successful and then I immediately flashed back to PA and it is working. Going to give it another shot and keep the stock rom on my sd card this time in case I get stuck in a pinch.
I jumped the gun, phone activated fine but signal drops in and out randomly and will not connect to 3g. Just reflashed to stock again and everything seemed fine but signal was still back in and out. Checked under status and PRL read "0" tried updating to no avail so did the dialer code and it did the activation and all is right in the world again, or at least for the moment.
Just trying to figure out why when I flash Paranoid all my settings just disappear
*edit*
Just flashed back to PA this third time after fully making sure that the phone was working and had 3G data and all was right with the world (my phone). Will update if it goes South again but as of right now the phone is behaving properly. Maybe it just wasn't working right the first time and I didn't notice since I was on wifi. Only thing that keeps me from thinking that is I didn't get the Activation message until 12 hours or so after I had flashed and had been using the phone. /shrug

My GNex (yakju) is losing data connection so often now since I received 4.2.0 it's not even funny. I updated to 4.2.1 and problem is still there. The only way to get connection back is to toggle airplane mode a few times or reboot.
Background: I had this problem when I purchased the phone which was on 4.0.1 originally. I eventually found out about this site and updated to 4.1.1 using mskip's GNex TOOLKIT. Miracle, no more data connection loss! I could now fully enjoy the GNex and has been functioning flawlessly for several months. When 4.1.2 came out, I updated OTA and phone was still working perfectly.
Now 4.2.0 came out, received it OTA - horror: my connection loss problems are worse than ever So I though OK I will just go back to 4.1.2, but problem remains. OK then I'll go back to 4.1.1, but problem remains! Reset factory settings, flashed phone several more times re-trying 4.1.1, 4.1.2, 4.2.0, 4.2.1... no success. Checked APN, reset APN as per provider settings (Telus in Canada) but without success.
My connection now drops all the time. I miss about 90% of my calls, notifications, etc. Google search finds several people with similar problems and indicate some GNex have hardware problems and the solution is to ask Samsung for an exchange until you get a good one but often takes 3-4-5 phone swaps before getting a good one.
I just find it is a very strange coincidence that my phone "broke" immediately after updating to 4.2.0. Anyone has any ideas how I could solve this problem (other than going to Samsung for a swap because this is a nightmare road I'd which to avoid)?
Had a similar issue lost service altogether, used mskips gnex toolkit to wipe all then download and flash stock google image, immediately fixed issue so did one click root busybox etc and regained root then flashed a custom rom, no dramas since and smooth as butter.
Hope this helps am somewhat of a noob so dont know tech stuff but toolkit did the job and fixed it, its a software bug methinks, many thanks to mskip and xda

I already re-flashed my phone countless times with with the latest gnex toolkit trying various ROM setup such as 4.1.1, 4.1.2, 4.2.0, 4.2.1 with no success. Then I tried flashing several different recent or older radios (UGKL1, UGLC1, UGLH1, XXLF1, XXLH1) with again no success. Now pretty much anytime I wake my phone, my connection is grayed out whichever ROM (stock) or radio I tried.
I haven't tried is trying all radios on older ROMs yet and I only tried the different radios on 4.2.1. Then again I feel I shouldn't have to do all this and think its getting ridiculous, I mean the latest build should be reliable.
Hello, I have a problem with my phone that is driving me insane. This problem started happening a few months back when I rooted my phone and installed AOKP milestone 6 maguro. Every day, at least three times, I have to turn on my airplane mode and turn it off (which is glitchy and takes way too long) to get my data back. Not a big problem, but its INSANELY annoying after this has been happening for months.
Why do I keep losing my 3G connection? I'm with Wind Mobile, and my APN's are correct. Should I just go back to stock?

Apologies for not responding. I forgot about this post. I didn't return to stock yet. I'm disappointed to hear that it may be hardware. Probably will just relock it and unroot it and stuff, return for fixing if its still messed.
make a back up first before you return to stock
flash the latest 4.2.1 from google or just flash the latest radio if you wish, i'd just go with stock image first just in case its your rom ****ing up.
https://developers.google.com/android/nexus/images
if you are still losing connection with stock rom AND stock baseband everything stock with latest update, then yeah, it is probably hardware issue.
