[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.

3G/H/H+

Ok so I have a Telus model and this started a few days ago when I flashed an AOKP rom...
So, I don't get LTE in my area and have always had 4G (or whatever they say it is).. Ive flashed many TW roms and ALL the roms have displayed 4g...and for not having lte, ive been very impressed with the speeds.
However, since this AOKP rom I installed (which was awesome, just wanted to go back to TW), it displayed H+...
Now, I know what h/h+ is and all that jazz about the carriers.. My issue is, can't flash any TW rom now without getting 3g/h/h+ toggling back and forth nonstop and the speeds are horrible!!! Can barely download in the store and loading a page takes a while.....and yes, I realize that its supposed to help with battery and whatnot but I don't like it and just want 4G back!!! lol
So far, I can only get 4g back when I unroot and do a hard factory reset...
And even then, it still shows h/H+ until I go through all the system updates.... then, I go to install another TW rom and I'm back with the h/h+ again...
I have tried the att fix, installing latest modem and still no luck.
I even asked to do a factory reset on my fathers phone (we are on the same family plan) and his shows 4g even when installing any TW rom...
Does anyone out there know what I did wrong?? also, my imei number is fine..
Thanks in advance to any advice or help

Yes apn checks out just and on LTE/GSM/WCDMA.
Its weird becase my father has the exact same settings. And again, showing his 4g.
As I type this, im on 3g and when I send, it will turn to h+. Speed is horrible

So it constantly switches between 3g, H, and H+ ? Have you downloaded a network signal app to see what kind of signal you are getting and strong it really is ?
When you say you have done a complete unroot and factory reset, what method are you using ? Is this where to flash an unrooted stock firmware from lets say Sam Mobile and then done a factory reset ? Or are you just doing another type of unroot ? When you root what method are you using ?
You stated you are on a Telus model but flashed an at&t modem ? Are you on AT&T service ?

Getting 5753kbps download and 905kbps upload .
Whereas before my kbps were always around 11-12000kbps for the download speeds.
I always flash back to stock rom using odin and then factory reset.
Oh sorry if I stated that wrong. I tried an att fix as well as flashing the most recent modem for my telus device but both fixes did nothing.
Again tho, ive done this so many times with TW roms and cant figure it out..
Im currently trying to go back to stock and use the most recent CWM to flash and see if that helps

It doesn't seem to make sense that even after going back to stock unrooted 4.0.4 (or what ever it cmae with from the factory) you still have signal problems as the odin packages would flash the correct modem once you install.

Sounds like network issues.

Speeds of ~9000kb are actually pretty standard for actual usage with H+/H/3G. Don't worry about speed too much. And for future reference 4G is H+, its just another name for it. The common misconception is that 4G is LTE which it is not.

Thank you for your reply.. yes I know what it means and its pretty cool. But again, my father and I are on the same plan, with telus with same phones. Going back to stock rom with odin still shows h/h+ when it should show 4g. I kniw they are the same, but the fast dormacy is a pain in the rear. My father and I are currently running the same rom with the same service getting 4g on his and h/h+ on mine

No kidding!! Ive done this a thousand times and have never seen it before..so starting to grt frustrated when told that its normal lol..
So when I get to 4.0.4 its still h/h+, but when I update the first time from samsung, it then shows 4g and my speeds are back to normal. But then as soon as I flash afyer rooting, it gies right back to h/h+ fast dormacy with no way of going back unless i do a hard factory reset again.

Are you sure it is the exact same version that you are running? He didn't update at all, no matter how small the update? If you flash from odin, everything that you did in the past should be overwritten. Go to settings->about phone and tell me what both of your baseband/build versions are

Ok so the baseband is I747MVLDLK4 and build version is 2.4? lol
I will unroot and flash back to 4.0.4 with a factory reset and then update this post.
Really appreciate ur help
Btw.. I downloaded the whole odin/telus stock tar md5 and recovery about a year ago and have been using that for both of our phones. I will update in a coupke of hours
Also, when I flash back to stock and get the 4g back is there a way to save the modem and/or other files needed to bring over to another rom?
Ok so here is the image I took of my phone info..
I would have to put my fathers back to stock to see if there are the same... but Im now on 4.0.4 with h/h+ still present. Im gonna do a hard factory reset to get the 4G back and then see about trying other things.

Yes, this I understand... but with the 4G displaying, I get NO fast dormancy causing download issues and on top of that, my download speeds are 11-12000kbps.. when showing h/h+, Im getting half the speeds and constant toggling from 3g/h/h+ is driving me up the wall!!
again, Ive never seen this on my Telus TW roms..
I will be unrooting and going back to stock with odin...then doing a factory reset..it will still show the h/h+ unless I do 1 of 2 things....either do a hard factory reset using *2767*3855#, or by simply doing a Samsung update...then after one of those, 4G will be back and so will my speeds.

general rule of thumb, touchwiz roms cannot be built from source. The only way to mess with these roms is with winzipping and adding apps (i call it bloatware) to be honest, if you want customization go to AOSP. Every single time I use a touchwiz rom no matter how smooth its says it is, I get crashes, bugs, irreversible issues like you have, loss of connectivity, the list goes on. Thats all because of the limitations of not having source code, I would recommend you drop the touchjizz and find an AOSP rom you like, if not, stock rom is the way to go.

I agree.. I'm under the impression its the other way around.

Hey just curious.. I was reading about going back to stock and making a copy of the qcn??
Can anyone confirm that copying this and then injecting it after a flash would work?

That your opinion is somehow fact. That somehow using a TW rom will just give you bugs and ruin your phone, as if a custom rom doesn't have glaring bugs as well. It's quite awesome the amount of customization that the dev's on the touchwiz rom's are able to inject into their rom's. Anyonr who thinks it's just unzipping files and adding apk's is uninformed. Is it on the level of PA or AOKP of course not but with more customization you add the possibility and almost the certainty that you have bugs and instability. We are quite spoiled on the i747 that we have kt and Task developing rock solid custom rom's. Most out there don't have that pleasure. If a TW rom on here is unstable it's because the dev has fallen short some where. I'd say I fall in this category and I am certainly no dev, just a noob cook. Equating TW rom's from 2.2 to the ones we have now is just fallacy. I do agree not having the source code put's dev's on the
In general I have had to deal with more bugs and instability with custom rom's than I have with a stock based rom (stock meaning what came on the phone). Yet that is not a gripe but merely the fact that I don't like to deal with the little things that pop up on custom rom's, and I prefer the aesthetics of TW. Crazy I know as many find it ugly.

[Q] Band Handover/voice network issues

So I have been waiting patiently for the 4.3 update to roll out to me OTA with hopes that it would fix my issues but my phone has been saying download interrupted and so I have gone back to completely stock and triangle away to get my device status back to normal but it still wont let me download. When looking around for other possible causes I saw that my build number is JRO03L.I747UCDLK3 which comes up as a build number for a nexus 7, the correct build number for my att should be JRO03C. I have no idea how it got that way but I am wondering if the person who bricked it might have put the wrong version of the bootloader or some other part of the firmware on and it somehow didn't brick but is detecting a conflict and not letting me OTA. Or that is what is causing my cell network issues as well. Wanting input from a a few devs as I am not 100% sure what the first part of the build number represents.
Ok guys and girl, I am having a really weird issue with my Att Gs3 that I wanted to see if anyone could help with. To start off a little bit of background. I Hard bricked my s3 in August, sent it for tag and got it back working and stock with no issues. All I did was root the phone for fear of messing it up again but it was running all stock without problems for over a month since the unbrick. About 3 weeks ago I went out of town within the state but a ways away, I was talking on the phone with a co-worker right before leaving town. At some point that evening I get a a text from my wife asking why I was ignoring her calls, I had never received them and according to my phone was in the middle of prime 4g lte zone in San Antonio but I was apparently only receiving that lte signal and the phone was not switching to the voice network on 4g to make or receive calls, I was even able to voice chat with my wife but I couldn't just call her normally. After returning home I was still unable to make or receive calls unless it was right after a restart and I had to try about 15 times, so I called att and tried all of their bs which didn't make a difference at all. Looking around on the internet I found the number that you can put in to get into service mode and switched it to gsm or wcdma only and voila I could make calls again. The only problem with that being that I travel within a city for work and move from 4g to 3g to edge all the time but if I have it set for wcdma only then I have no signal and have to take the time to pull up service mode to switch back and forth. So I tried going back to completely stock again by resetting/ formatting all and flashing the stock rom via odin, my issue persisted so I also decided to flash synergy rom (which I was running prior to the hard brick) and then intergalactic because I saw the fewest problems with it to no avail. I have flashed each stock modem new and old which made no difference at all. Today I was messing around in service mode and found an area that was called handover, in that subsection you have the option for checking the phones ability to switch from gsm to wcdma and back as well as to hspa, when I select any of those options I get the message "temporary block due to build e" or " temporary block code".
I was wondering if anyone has any ideas about what the possible problem could be, imei, modem hardware, or a stubborn stuck modem firmware setting.
I was also wondering if anyone had any experience with figuring out how to re-enable handover because that is where I feel my problem is, either through adb or any programs that let me force change the settings, I would also be happy if someone knew how to turn of only LTE and have both gsm and wcdma on at the same time.
Any help would be much appreciated, I have tried everything I know how to do, but am to the point where I am forced to look at new hardware because my wife is pregnant and I really needs to be able to get a hold of me any time.

if you have CM recovery or TWRP you can go back, wipe everything even twice could help, then flash a stock rom reboot and see what happens
if that doesnt work go back to odin and install stock firmware 4.1.2 from Samsung but again you have to wipe data/factory reset
3rd if that doesnt work, try to restore your EFS folder/files using this link http://forum.xda-developers.com/showthread.php?t=1725839
that link has everything, how to fix it, anything you need to know
BUY a new phone or use a different phone if all the options above fail

The backup restore/fix imei and data restore tools link doesn't go anywhere, does anyone have a link to the restore tool? The only version I can find is for the non us version of the s3.
I did at least use the tool for the 9300 to find out that I have some 000 for s/n and other numbers (see attachment)
is there a patch out for us gs3's to fix this like there is for the i9300?

I think I can help, I just need to pull up some files and I might get you the software or program I used to back -up and restore my EFS folder/files
Even fix it, so plz hang in there........will report back later on

Thanks a bunch, I am still trying all kinds of stuff but I feel pretty certain that the problem lies with a messed up efs and I don't think I have a backup unless doing a nandroid covers that as well, which I am not seeing that it does. Any further help is appreciated, is this something that a local cell repair shop can typically fix or is this a possible new phone situation?

this is the software/programme i used to back-up, recover or even fix my EFS files (if they are corrupt and can be used) NV items reader writer
type it on google and pretty sure you will find something , try different links and again am sure you will find a download
have you tried flashing the new 4.3 stock firmware and modem follow this link for everything http://forum.xda-developers.com/showthread.php?t=2498233 or you can wait for AT&T to release the official 4.3 firmware and that will be 100% satified to be stable and will fix all your EFS/IMEI problems FOR GOOD :laugh:
i have the NV items reader writer software that can fix your problems but i dont know how i can share it with you without breaking any rules
ULTIMATE/final solution send it to MOBILETECHVIDEOS and will fix it like its nothing, take it to samsung and have to play some ball, or BUY A NEW PHONE
tried kernels (idont think it will make any difference) but its good to check

I have tried all the other versions but will try the 4.3 what's the name of that software so I can try and find it or of you have drop box you could pm me the info and get it to me that way . In the meantime I found an fusion 2 for 38 bucks from att so I can get calls for the time being.

Bump

[Q] Please help. Modem for n7105 4.4.2

Hello I Updated to Kit Kat 4.4.2 about a month ago & everything has been working fine. but recently my network has been dropping & emails, Facebook etc taking ages to load & I have to either try & switch on/off flight mode to reset network or find new network to get connection.
Do i need a new modem or is it just EE being a **** Network again
My rom is the stock Nordic n7105xxufnd3.
Can I get another modem for this to load through odin or do i need to revert back to 4.3 rom to get better network connection.
thank you to anyone who helps.

Do you have a custom recovery? If so nandroid (backup everything) and factory wipe. If not, it's worth trying anyway just less convenient without root or cus. recovery.
Basically there is little reason why your connection should get worse expect hardware failure or network problems, this could could be as simple as a bad contact with the sim, but it's worth ruling out software issues first as they're normally fairly simple (and free). It's also worth trying a different network if you can. It'll help if we can start ruling more things out.

See if that makes a difference.

Did you ever get your signal to stop switching on EE mate? The same thing is happening to me and its a pain in the arse. I'm considering changing the modem but I don't know which one would be good for EE.

Signal problems after root, twrp and reflash

I'm having an issue with connectivity, please help if able.
1. used CF auto root method from this link https://forum.xda-developers.com/sp...uide-links-files-update-root-restore-t3366862 when I went to TWRP it would say recovery is not seandroid enforcing, but would go on to TWRP anyway.
2. made backups
3. connectivity problems started. could make and receive phone calls in certain places. dropped phone calls and went straight to roaming with unstable connection.
4. reflashed stock firmware from Koop1955's post
5. noticed I still had connectivity issues even when back to stock
6. reflashed twrp and root
7. still have connectivity issues
8. not able to activate through hands free activation or dialer codes.
9. can see sprint then it goes away. will get LTE in other places
10. Any ideas or direction to how I can start to affirmatively diagnose issues?

@Saafir, I have been trying to help, but I am out of ideas. Any suggestions for him?

Tried dialer code

I tried that dialer code on it, it goes to SCRTN then reboots and goes to Hands Free Activiation where it fails all times.

Thanks

Providing you have your MSL # do the ##data# menu, and make sure you have all of the LTE bands enabled. Carrier aggregation too. Other than that not sure what to recommend besides a trip to a Sprint store.

I have MSL code and looked at ##data#. All bands are enabled on the LTE front. Would placing a new SIM card work? or should I try going through more advanced diagnostics? The phone works and makes and recieves calls as long as i'm not in a bad spot. The thing is, there are ALOT more bad spots and it shoots me to roaming in the same area my fiancee has LTE and good reception. Same phone, same service. Any way this information can help?

One more thing

I had to get the phone repaired about a month ago. They placed a new daughter board completely on it. Could this affect it after flash? I had no problems with reception before root and twrp so I didnt think this would be relevant but maybe you guys know how to check if that is where this issue is coming from.

Doing a wipe via TWRP and then flashing the TAR should return the phone to stock state. Since the problem happens when you are unrooted and back to stock recovery (as well as when you are rooted and running TWRP) it seems likely that it is hardware. If I were you, I would do another wipe (System, Data and caches) then Odin the latest TAR and bring the phone back to where the repair was done. Tell them that you took the latest OTA update and the phone failed and that they need to fix it.
