Modem Problems, not finding the mobile network - Galaxy Tab Android Development

I A few days ago I installed the CyanogenMod rom and it was all working fine.
This morning I noticed I wasnt getting ANY mobile data and I cant seem to use the phone either.
Can anyone please suggest a fix? I am happy to change modems/kernels/roms.
I would like to say im fairly experienced at this stuff (being hacking around with my own roms for a few years) but im am stumped
Thanks for any help

not trying to be an arse, but you could try posting in the QandA forum - this is for dev. prob get more help there.

And when you do, how about adding some details, what rom, baseband, and stuff from the phone info

You need the JK5 modem if youre on CM7.
I had the same issue yesterday and it scared the hell out of me haha.

[Q] WIFI Unable to connect....

This just happened about 24 hours ago to me. i noticed it says "unable to start wifi" also i think that affected my wireless tether.
My phone has the simple root done to it. I have Astro File Manager, ROM Manager, and like i said before i did the simple root with Unrevoked3. i am a mac user, i dont know if this second paragraph of information helps.
What should i do? should i just wait for the update to 2.2 that is supposed to be updated to my phone sometime soon? i tried restoring from an old backup and also tried to do a full system clean as well but still same thing. I am a newbie to this but i feel as though i have somewhat of a grasp on this.
Any suggestions or help would be greatly appreciated
You guys sure keep the mods busy around here.

that suggestion didnt help
I feel your pain, most responses around here aren't helpful... just negative... you'd think that if someone took the time to reply they'd just share... typical forum behavior though.
I can’t seem to find a clear answer on this… some say it works, others say it’s broke.
*watching in hopes someone can help*
yeah i am just hoping i get the 2.2 update soon and it fixes it. so i am guess i am gonna have to wait until then and then take it from there. unless someone has some ground breaking suggestion. cause, i've been looking around and it seems like this is a problem thats been occurring as of recently.

I have sky raider 2.5.2 and my wifi keeps trying to connect then obtain ip address then disconnects and keeps trying all over again why please?
so since nobody gave me any good feedback i decided to take on the task like a blank canvas.
Step 1: Reinstalled original Kernel
step 2: Full Data/Cache Wipe
step 3: reuploaded all of my data from last backup...
it appears everything is working fine.WIFI works great!!! I need to double check wifi tethering though. if anyone is interested i can repost if tethering is working.

4g not working :'(

Ok so I have been playing with a lot of roms recently trying to find the perfect one that suits my needs and a good kernel to go with it. I have found the perfect combination with excellent battery life and exactly what I was looking for in a rom/kernel. But the problem is that now I finally have everything great except I can not get 4g no matter what. I have tried EVERYTHING. Hours of going through the forum trying to find people with similar problems and I can not seem to fix mine no matter how hard I try. I am currently running CM10 stable version jelly bean 4.1.2 with baseband t999UVLI5 and leanKernel-tmo- 1.10-+
Please guys I have tried all different modems and playing with apn setting and nothing. Even called tmobile and nothing. Thank you so much in advance!
I really want to get out of bed and simply search "no 4g" and show how you didn't search lol. Unless your imei is still intact, then I'm not sorry.

Look, I'm trying to assist you. If all you are going to do is plead for help over and over again without providing answers, then I cannot help you.
Have you done anything to the phone since you last had stable connections?

I think he's implying that that's how it's always been, or possibly that he has done all of this within the last few days. However long it's been, to me it doesn't sound like a recent issue that has cropped up.
Just my obversvation though. Unfortunately that's all the help I can offer heh

I don't use a MVNO, so I am not sure which regular troubleshooting steps would clear away your carrier settings. (I'm thinking using EFS Clear in Odin is the only concern, but that is sometimes needed for modem issues.)
Based off that rom's thread, you must be using the NS4G modem. Since your issue is with connectivity:
Perform a CWM backup of your current setup.
Flash an Epic modem rom and FC09 modem. (You can flash the modem using CWM. There's a thread in the dev forum w/ links.)
Try testing connection again.
I'd normally tell a Sprint Epic user to boot into FC09 multiboot and update profile & PRL, but I don't even think the PRL update would work for you. I'd then say, start from scratch by using Odin to flash FC09 with repartition checked. If they still had issues with connectivity, then I'd recommend using EFS clear in Odin when reflashing either just the FC09 modem or the entire FC09 tar.
Because you are on another carrier, I'm weary of suggesting you use Odin so quickly. If you haven't already, dive into your phone settings and document your carrier specific info you changed to get it working. This way, if you end up doing something that resets your original changes, then you can reconfigure it.
So give the suggestion that is listed above a try.
Since I'm very much a noob myself, I'm only tossing this out to possibly trigger an idea for someone else: Would perhaps the issue lie in the Build.prop or one of those similar files? I've poked around so many of them I can't remember which hold what tidbits of info... I know the Build.prop holds most of the primary carrier info, but I seem to recall another one that stored a bunch of info for a bunch of the other carriers (though that might have been for roaming and may not be of any help here).
*shrug* Otherwise, I's gots nothin' lol

[Q] WiFi And Mobile Data At The Same Time?

I would like to know if I can have WiFi and Mobile Data on at the same time. I do not get MMS messages til I get off WiFi and also I can't get on my T-Mobile App to check minutes and data. It Keeps saying "Sorry, no data connection is available" I looked in my settings and said Mobile Data is disconnected.... Is this normal? Thanks In Advance.

Hmm... to be fair sometimes a lack of response is more a lack of confidence in any particular response that might be given. At times repercussions get ...awkward... for saying things that others might find ill informed, and as such a tendency to not say anything unless rather certain on the answer develops.
Anyhoo - I hadn't noticed the fact that the mobile network state listed itself as disconnected when connected to wifi... but ultimately (opens self up to possibly saying something stupid...) I can think of no good reason certain functions of the phone (at least mms or the tmobile app) would depend on mobile data being connected while wifi disconnected. Doing a quick test on my end - both of these functions seem to be behaving as expected while on wifi (tested with wifi calling NOT on, not sure that would throw a wrench in anything but you never know) - does the issue exist across wifi sources? That sort of thing might be something to bring up to a TMo service rep - not sure they will be of any help but given the response you've had here it couldn't be much worse, right?

Thank you for your response. I finally called Tmobile and they told me that their apps will only work on mobile data and are not meant to work over wifi even though they say my mobile data will always be on it just goes into a low power state and that MMS has to be set to auto receive which somehow was not checked. Everything seems to work fine. Just one question for you. Did i read that you said you could get on your tmobile account app with WiFi on? Again thank you very much for answering me back. Just was have a bad morning because i get alot of MMS messages for work and it got to me... Also I'm one of those guys that no believe in a stupid answer. If someone's trying to help no matter what they say I'm just greatful for the help

I was able to, but perhaps it was just a trick of app cache as opposed to it actually working... strange they require data, you'd think if it was that much of a need they'd force it to engage and wake up the low power state instead of forcing you to turn off wifi. Ah well, learn something new everyday Sorry I wasn't more help

[Q] Nitro HD think I broke my data

Ok so first off, been using XDA for a while now to root various things, you guys have always got me what I need to get things figured out on my own, I have never before this day had to request help and for that, you guys are legendary.
Now I am semi newbi here, I know whats what for the most part but I have a hard time holding information in my short term memory so I am sorry if I miss little things
On to the problem!
So I got an AT&T LG Nitro HD P930, on ebay, I then spent the better part of a day rooting it, took me a lot of work but I eventually got it rooted and all that jazz, everything was going great... but everything changed when the fire nation... wait no... when I put CM9 on it, that crashed quite often, so I put on CM11 to check that out, no Data, so I rolled back one to CM10.2, and still no Data.
Could I have missed something?
Edit:
I thought at one point the ImeI might have gotten pushed out, but I double checked that and it is there, I have noticed at times I look at the service and it says I have 4 bars and an E next to it like back in the 2G days, but rarely and I have not had it stay long enough to test the data but if I get the chance I will edit and leave what happened here.
Also to note, I do still get random crashes but I can live with that.
P.S.S. XDA Devs are the shiznit, thank you guys for many years of amazing rom's and HP Touchpad support, my tablet is nothing without you guys!
Potential fix
Ok so admitadly I may have jumped the gun on not finding anything via the search function, I did find something digging around that might help me out. just incase anyone else checks this thread due to the same issue I will post back here if it worked, I found the fix on this thread

Issues "Unbricking"
So my second go around seems to be having trouble taking off, I cant seem to get the V10F to flash to my device following http://forum.xda-developers.com/showthread.php?t=1597488 exactly as it is. always just reboots into my old OS. Any advice?
Edit: Noticed I forgot to rename V10F correctly and tried again, seems to be running smoother, feel like a total noob...

I had read something about that and had a backup of my APN but it turns out you cant flash APN data after 4.0+ or some such nonsense.
In the end I managed to get the root to take hold after restoring it from unbrick up, now I have CM9 on it and it is working just shiny. so this thread can be deleted or closed or whatnot.
If anyone would like a step by step on what I did I would be glad to post it but I doubt anyone is interested.
Good thing you got it working. And CM9 was so nice and stable for the Nitro. I often think of reverting back to it just for its reliability.

Its been a while since I did it but I will see if I cant gather all the resources I used, but in the end what I had to do was re-brick it, reverted back to stock everything to recover and re-rooted it all again, then I just skipped CM11 and went back to CM10. Now I am in a whole new **** storm haha but thats a story for another time.
