[Q] I installed a new ROM, now I have no cell service. - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So the warranty on my SGH-I747m just expired, so today I decided to install a custom ROM. I installed CWM, made a backup, then flashed the latest d2lte nightly of CarbonRom. Now I have no cell service, and my APN menu is blank. If I try to enter in my APN settings manually and tap 'save', it doesn't save - the list remains blank. I tried downloading Tweakker's APN app, and it says I have no SIM card!
I know my SIM card works perfectly fine, because I was making calls and texts and had internet just hours before I decided to install this ROM. So what the heck is going on here?! This would be the third Android device I have installed a custom ROM onto, all on the same carrier, and none have given me this trouble before.

Is your bootloader and modem up to date?

I can not get any radio to work to make or receive calls! I flashed everyone out there and still can not make or receive calls. What method can I use do to get it to work? I flashed radio from TWRP with Factory reset, delvik and cache and then flash with no wipe and I just cant get that or any radio to work. I just get AT&T when I do a scan, which I use T-Mobile. When I choose search in settings in mobile networks, still nothing. When I try to use phone, it always says no network avail. and yes I have data box checked off. It just seams lately any Rom I flash after the newest stock, (JB) I have radio issues, can not make or receive calls. I even erased, wiped everything and started from scratch with stock. Phones works fine, but when I try any ROM, no calls, no matter what radio I flash. I must be doing something wrong. I must say, that I flashed many a Roms before and all worked well until now! I even download same radios in case I got a bad download. I can use kernels, such as Tiberius with Stock JB. I Flash a Rom and no radio, no matter what Rom. My version in stock is UVMC6, SGH T-989 phone. (T-Mobile). I know all phones are different and thought maybe something in stock files I might be able to use, but don't know which files. I am not a dev by any means and thought if I could use the stock I have now can work with the any Rom here. I never dirty flash anything, all Roms work that I flash from sd card, just not able to use phone in any Rom at all! I thought maybe I can manually put in APN, but I have no idea were to get address to enter. I am from Delaware if that matters as far as APN. Can anyone give any suggestions of what they did to get radio to work?

Verify your APN settings are correct. If there isn't a t mobile APN set up than try creating one. Also go to Settings > About Phone > Status and make sure your phone has a valid IMEI number (anything other than 0)

Thanks, yeah after all reading and troubleshooting it seems APN is where I have to create and/or edit! I found APN settings on Google and wrote down the settings that is on stock Rom where phone is working and will try it. Thanks for heading me in the right direction.

[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.

[Q] How to enable network data after installing Cyanogenmod CM11 M7?

I tried flashing a custom ROM for the first time last night and so far I am really loving it. The only problem is, after flashing the CM11 M7 ROM it wont access any data over the cell network. I did figure out that if using Titanium Backup I restore my stock ROMs 4.3 data only from the Phone/Messaging Storage (SMS/MMS/APN) then reboot the network data does work. However, this causes the SMS to cease functioning. As soon as any app (default messenger, hangouts, 2-3 others I tried from store) tries to open it immediately crashes. Interestingly, it also will not allow me to restore my SMS records using Super Backup at this point. If I go back into Titanium backup then wipe the data for this process then the SMS starts working again, but all the old messages have been cleared, and as soon as I restart the phone the Network data is not working again.
Any ideas on what to do? I am wondering if maybe I need to adjust something in my APN profile, though I have absolutely no idea where I would get the information to do this.
This is what I am working with:
Phone: Samsung Galaxy S3 i747 (AT&T) -- [though currently I am using a TIGO sim card in Guatemala, wonder if this could have anything to do with it? was not a problem prior to switching the ROM though]
ROM: cm-11-20140608-SNAPSHOT-M7-d2lte.zip , the Cyanogenmod CM11 Snapshot lte release from yesterday
Android Version: 4.4.2
Baseband Version: I747UCUEMJB
Kernel Version: 3.4.91-cyanogenmod-g9b9605b8 [email protected] #1
Anyways, only having one or the other of my network data vs sms working is not really an option for me, so need to figure something out.
Thanks!

I apologize in advanced for not answering your question.
Is your issue that you cannot even get a signal with CM installed? I am also having the same issue.
Did your phone get signal/mobile network with the stock ROM? I am unable to find out if mine will work right now because it would take me a few days to download the stock ROM image...
Will be following this thread...
Mike
Have you checked that the APN on your phone is the right one for your carrier? Google search apn tigo guatemala galaxy s3 Many useful results will come up.
Ok here is how this played out. I did just need to reset then re enter the apn info for tigo in Guatemala. I actually managed to pull this info out of my pre flash backup from when I was using the stock Rom, then wipe the data for the process mentioned. This restored sms functionality and I then was able to manually enter the apn info (if anyone needs the Guatemala tigo apn info just post here and I can grab it when I am next at my cpu). I find it interesting that the apn info was automatically present and correct when I was using the stock Rom, but when I flashed cm11 over it was not there.
Just arrived back in the US and popped in my AT&T SIM card, everything worked fine right off the bat with it.
In answer to your question, after flashing cm11 I did have signal, but only for calls and sms. The data component of the network was not recognized.

Can't make calls out (Random only on network mode WCDMA/GSM (Auto Connect)

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.
This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.
Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.
What APN (Access Point Name) are you on ? Also what is your Preferred Network Type set to ? Its located in Settings > More I think.(I don't use Stock Firmware)

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here
I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..
Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.
I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.

Gpad 8.3 update to 4.4 2 no longer able to read sim card from tmobile.

Updated to 4.4.2 today via ota. Was originally a Verizon 8.3 lte, switched to t-mobile. Was able to toss a sim card in and update apn ran fine. But after ota update today it no longer reads tmobile sim card. Have updated apns, continuing to get notifications that tablet activation incomplete, your tablet will try again when you restart. Have restarted plenty of times, on boot get welcome to Verizon red startup screen. Then goes to straight to screen unlock. Anyone with a idea of how to fix this. Tablet is rooted.

i run this line of code and i get operation not permitted , im not sure what im doing wrong. ive tried it over a few diffrent computers, and have also ran adb of the tablet it self thru term... any ideas?
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
also its rooted with TWRP and CM12.1 installed but i have no cell service the options in settings are grayed out i cant enter and settings manually. and the Network app wont work to change anything
want to set it up to runn off AT&T the best i can
Did you give terminal Superuser permissions with "su"?
yes super user was granted
I don't know what's wrong then.
You could take my ROM zip from my signature, delete all the partition IMG files out of it, put the modem.img you want in, and edit the updater-script to remove anything having to do with flashing the other partitions, then flash the resulting zip in TWRP. Make sure you know how to recover and have everything saved that you want to keep from internal storage in case you do something wrong, though.

You know, I haven't been able to get mobile data working on any CM-based ROM on the VK810 yet, so that's probably your trouble. If you want mobile data you'll have to go stock. Some people had some luck on CM-based ROMs but then eventually it stopped working. I didn't have any luck at all.
Thank you for the info, I think I'll just wait for a possible workaround, until then I'll just use internet share from my phone.... That and I haven't the foggiest idea hownto do what you told me to do with the updater and what not lol , so rather than really screw things up, I'll just stick with WiFi..
