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] SPH-L900 Flashed to Cricket: Unable to get service with custom ROM

I just got a Note 2 SPH-L900 (Sprint) it has a bad ESN for sprint but my intention was to flash it to cricket. I had noticed the same thing before the flash over to Cricket (I was messing with it over wifi etc and I did flash cm10.2 nightly just for the heck of it, then back to stock) but I could not verify service since I am not a Sprint customer. However the issue seems to not be carrier-specific.
When I flash custom ROMs I do not have service. No call, no data, nothing but wifi. The signal bar is empty and I get a big "?" Where the carrier is supposed to be. Also under "status" there is many blank spaces, no phone number, no carrier etc. Upon factory restore (which was done 2 or 3 times to ensure a bad ROM flash was not the culprit) the service icons and settings come back as before and everything works well.
I have tried two separate ROMs that give me the same issue: cyanogenmod 10.2 nightly
Rootbox jelly bean
Anyone know what may be wrong? I do not think this has to do anything with the flash over to cricket, since before it was doing the same thing. Any setting/procedure that I may be missing?
Edit: I did not do anything with kernels. My stock ROM android version is the 4.1.2

Well, i got it working now!!! i did reflash the modem to the latest MC2 version, then installed a custom kernel, Sleshepics the governor 1.7.
Then i reflashed the CM10.2 nightly and i magically have signal and data working.
SO EXCITED!

trying to flash my galaxy note ii sph-l900.. need help
i went to a couple of places and they said it couldnt be done.. it has low signal ... it only works on certain areas..
need help

Well it all depends on your signal. I live in Austin TX and cricket has great service here, with some dead spots out in the country (no big deal). 3g speeds are as fast as Sprint's 4g LTE.
The problem I was having had to do when I was flashing custom ROMs I was lising service.
I updated the modem drivers. It did the trick. I havent list service since and ive flashed like 6 ROMs so far.

[Q] Can't send sms and greyed bar after cm 10.2

Hello fellow xda members. Well after searching for a solution for my for nearly a week now i figure i should post the question to see if i can get an answer. I did search around before hand and tried many solutions but to no avail.
Background, I have a sgh-t999 that's apparently unlocked since I've been using a fido sim card in it for several months now. when ever I'm running cm 10.1, I have full network access, texts, mms, 3g data, etc.Note: d2mtr is flashed to my phone and my model number gets changed to sch-r530, baseband: t999vvllh2.
After flashing to cm 10.2 RC1. d2mtr. I get stuck on the metroPcs network with out any way to manually switch network operators because the option in mobile networks is greyed out. Everything seems to work fine in terms of calls but besides being able to receive texts messages i can't send them. The signal bar seems to be empty or greyed out yet it still picks up 3g data. I've vigorously checked my apn settings to no avail. deleted the voice+ apk since I'm not in the US being in Canada and i'm all out of options right now. If i restore back to my previous backup ,everything works fine and i did check to see if I loose my imei number after flash.
I previously tried flashing d2tmo to my device but to no avail, assert errors. It would greatly be appreciated to get a response and thank you in advance for any help.
Edit: It's a sgh-t999v as printed behind the battery. I followed this guide http://forum.xda-developers.com/showthread.php?t=1775616 hence the reason why I'm coming from ICS. Looks like I'll have to reflash using ODIN which i was trying to avoid out of fear of bricking but it seems like my only option now.

Might not be the right ROM for your phone. Or it could be buggy. I've messed around with a few and finally found a great one that seems to be working well for me. I have the d2ltetmo. I'm running Liquid Smooth ROM with 4.2.2 and TWRP 2500 recovery. The ROM roots your phone as well. Any questions feel free to ask. Hope I can help!:cyclops:

I wouldn't flash D2MTR Rom to D2TMO. Too many differing things. There's a CM for D2TMO too.

Are you sure that's a t999? The baseband looks like the one for the t999v.. And it also looks like you might be on ICS firmware.. What I suggest you do is check the model number of your phone to be sure what model you have, after that update to 4.1.1 or 4.1.2 via Odin but make sure its the firmware for your model. After this flash your custom recovery, and then try flashing cm10.1 for d2tmo.. If your device bootloops after you Odin, enter recovery and do a factory reset.
Edit: check the model number by removing the battery and it will say at the back of the phone.. And the firmwares to flash in odin are in the development thread

Well after a long process of flashing stock jb then finding a proper method of flashing cwm since i had difficulties with fastboot and went with the dd if-of method using the terminal emulator. I am finally on a stable cm 10.2 rom, d2tmo, where everything seems to be working and intact. Thanks for the advice now i have the long process of restoring my apps and data and what not with titanium backup.

CM11 No Mobile Network, Mobile Network State Disconnected

Whenever I flash cm 10.2 cm 11 any rom at all I face the problem of no internet. So I go back to stock. I have my baseband, build # important stuff like that. I always have to take out my assert lines. So when I flash any rom the fine line will say;
;Mount
or something like that I delete all the assert lines and I was told to keep assert lines but just change them to my baseband and stuff. Any help would be appreciated. & btw the problem is it says Mobile State: Disconnected. But I'm in service too.

I have the same problem. Been searching for a while and trying different fixes, but doesn't seem to be working. I'm on ATT galaxy S3, tho. If someone's got a working ATT S3 and let me know exactly what ROM, gapp, modem, etc they used, would much appreciate it.

More info is needed, such as carrier. I'm guessing either Virgin Mobile or Boost if you need to remove asserts on any of the pre-unified builds (this would hold true for any ROM that has switched to d2lte from d2spr). If that is the case, then you don't have the correct APN's configured. Also, it usually doesn't hurt to be running the most current modem (MK3 for Sprint, MK5 for VM/Boost). Again, the more info the better, then people don't have to play Twenty Questions in order to get to the heart of the matter.

This may work...
So, after trying countless options that i found on this site, and after dozens of flashing roms, modems, kernels, booloaders, restores, etc... turns out that i was doing everything right and there was nothing wrong with the install or the phone itself. After contacting my carrier (PTEL Mobile) for the third time, (first time they told me they had an outage, second time they told me to set the APN setting correctly - neither of which was incorrect on my end or the cause), they said they will try RESETting the DATA on their end. And guess what - that worked.
If you think you did everything correctly but still not getting data, i suggest you make your provider to do the same, or at least pry them as much as you can about your problem and what they can do about it. I wasted to much time and effort (my poor phone) on this and the solution was simple, and not my fault. Hope this helps others.

Hiya, I'm currently having the same problem as the OP. Mobile state disconnected but it says I am in service. Using latest version of Philz recovery and I flashed the most recent nightly of the Cyanogenmod 11 -4.4.2 KitKat (April 5th, 2014).Carrier is Virgin Mobile, using Samsung Galaxy SIII SPH-L710. PRL is most recent one 33030 and modem is MK5. I did however, flash the rom without deleting the assert lines, since I did not know I had to delete some assert lines. Any help with this? Thanks.

Deleting asserts is only for d2spr specific builds, that doesn't apply to d2lte builds (hence the reference to "pre-unified builds" in my first post). Your issue is most likely also related to APN's. However, there are also known data issues on a lot of the latest CM nightlies, and also on the ROM's that rely heavily on CM as a code source. I would strongly recommend reading the last several pages of the thread for any ROM that falls into this category in order to see what other users are reporting along these lines.

CM11 No Mobile Network
Hey guys,
Noob here. I'm running CM11-20140428-NIGHTLY-jflte on a Galaxy S4 GT-i9507(international, optus) but bootscreen now says 9505(not sure if that's important).
I've had Mobile Network State: Disconnected for the last three nightlies. On CM11 M3 it was working all good, but now no luck.
So I've tried a few things and I've come to the point where I'm going to try the factory reset then reflash CM11 and fingers crossed it will work.
Can anyone talk me through the proper procedure for this? I've made a full backup on my external SD using CWM 6.0.4.7 and transferred it to
computer just in case. So would anyone be awesome enough to take me through it step by step.
Cheers,

hhmmm

Stock no APN settings at all
I have looked everywhere and found nothing for the last 3 weeks. I have a stock, sprint S3 on straight talk (my son's phone) it will not get 4g lte data what so ever. My phone is the exact same phone, and it does get 4g lte data. I tried all the basics ##72786# data on off check airplane mode...nothing. Mobile network state is "disconnected". So I opened data ##3282# to compare apn settings with my phone. I made sure everything matched, and when I get to "LTE APN Settings" I open it up, and nothing is there except APNs nothing, blank. Also missing is "Dial Up Networking" that option does not exist on my son's phone. He updated to kitkat (uggh) but the problem was present before that. Checked the phone, and it is not rooted. Funny thing is the phone updates with 4g lte running after dialing ##72786#, but that goes away after it completes. Texting works, but no mms (pictures etc.) and if I set it to cdma only it gets 3g, otherwise no data at all. Anybody?

"Mobile Network Is Not Available" Gio running CM 11

This is my first post here, so apologies if this isn't where my post belongs or I screw something else up.
So, I had a previous CM on my phone for awhile, whichever used 4.0.4 as memory serves.
Decided to try a 4.4.x based rom, and found a 4.4.2 rom which actually has a working camera, which seems to be always the problem with roms for the Gio.
I *thought* everything had gone smoothly, only to realize that my phone had no connection to the Mobile Network wasn't working. it took me a moment to figure out how to get that connection to work as this had not been a problem previously. my problem is the connection seems to be forgotten, on occasion, with little or no warning that I can neither make or receive calls nor SMS. Forcing me to search for the network, and reconnect.. shouldn't this happen automatically?
I hope I've provided enough information to be useful, if not I'd naturally be happy to provide what I can.
Thanks!
I'm on Virgin Mobile in Canada

I am using CM11 RC9 also meet the same problem, after a soft reboot then it show "Mobile Network Is Not Available", everything is work except using mobile network to surf the internet.
And there has another problem, sometime Wifi suddently no data transfer, I have to turn it off and turn on again, and it's working again.

A newly flashed rom or sudden reboots activates 3G network mode. So switch to 2G in these cases.

It's a 3g/2g phone and 2g coverage doesn't seem to be as good in this area. I could understand if I were in a low-coverage area but it seems to be intermittent, it will be working fine, and then stop, then it will have trouble finding a network after searching multiple times. even then, again, should it not be doing something like this automatically? It shouldn't require manual intervention every time I lose signal.

Okay, I was out with the phone today and it was constantly losing the signal then not being able to find any networks "error searching for networks" so I think this rom is not really in a good place yet, I'll have to try my luck with something else.

Looks like it was a noob mistake on my part, I think the baseband was changed to an American S5660 one, namely XXKS2
I was able to apply one from an older Canadian S5660M rom from samfirmware.com, namely UGKG3.
So I *think* it's sorted, but I'll keep you up to date.
