Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.
do you still have your IMEI or does it shows blank and unknown ??
I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

I have been dealing with this problem for weeks, and I can almost guarantee you don't have the radio right and that's the problem. http://forum.xda-developers.com/showthread.php?t=2385987.
Here is the link to a radio I just flashed literally 5 minutes ago and started running 4.2 roms after weeks of struggle and frustration.

That would certainly make sense!
He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.
Or wrong phone, sim or carrier.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!
Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.
Everything below is copied from another thread......
i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.

Hello friends.
First off, I apologize for not posting directly on the ROM's thread but it seems xda has a policy against new users doing so. Second, I'm not a complete newb, but I'm not by any means an expert either, so forgive me if I'm missing something obvious.
I flashed Twisted AOSP v4.0.0 ROM (jb 4.1.1) on my GSM (maguro) GNEX as per instructions, and upon booting I got no wireless (cell) signal whatsoever (hollowed gray triangle).
Wifi signal was OK, so I could still browse & stuff. But no making our receiving calls.
Any suggestions or thoughts?
Best regards.
Are you on straight talk? Just put your apn info in again.
edit -- sorry i was thinking data. maybe try flashing another radio?

Interesting, I thought the ROM didn't touch the radio. But something messed with mine for sure. I've got "unknown" in my baseband field in options -> about.
I've tried flashing several others, with no effect. But if I go back to JB stock or other ROMs, I've got no problem.
I'm perplexed.

I'd make sure the the RIL matches after flashing...
there is a thread around here, but I cant find it right now.. you can also use this app to check and update if there is a mismatch...

I've learnt a lot. Until today I hadn't had the need to flash radio, and had never heard of a RIL.
Well it turns out the app lists my baseband as unknown too, so it can't recommend a RIL that matches. Still, I've tried a few different ones and nothing has happened.
Anything else I can try?
I was playing around with the nightly build of CM10.1, and my radio stopped working. I flashed what I thought was the stock ROM back with Odin, but then I started receiving an, "Insert SIM Card" message whenever I tried to enable Mobile Data. So I flashed another one I found online. Still, with no luck (though the error was gone), I tried some radios. A dozen radios later, and I can get 3G data -- but still no calls or texts. I've been updating the PRL non-stop, still no luck (except when I'm roaming.)
I'm guessing the problem has to do with the many many files I have in /system/etc/firmware
Is there anyway I can get my radio back to stock?
Thanks!
you need a full odin flash with repartition. do not do this till you know for sure you have the right files to use. you can screw **** up with odin pretty damn quick. lemme search and ill see if i can find the right stuff for you.
EDIT:
I am downloading the files you will need to flash in odin. I want to see that they are indeed the correct ones for you to use. If you need help i can remote connect to your pc and help you out.
22 mins left on the DL and then ill be back

first rule of posting on any forum, "no question is dumb"
Rule number 2 " always ask if there is something you need fixed or need help with"
dont worry youre not dumb. though i may not be able to help you, the person above me hopefully will.
Quick answer from my own findings, the original stock ROM had a bug that doesn't allow it to see the SIM properly, but if you patch it (settings, update - or something like that), it will fix it (there will likely be a few rounds of updates).

The ROMs at Sumsung-Updates.com seem to be trustworthy. Are they?
Anyway, I finally got the issued resolved. It wasn't a radio problem that was blocking me, it was a badly linked Google Voice account. Sprint killed it, and now everything's OK (though I signed up again ^_^)

I had the same problem with the sim card thing...linked it to my wifi and it downloaded like 15 updates and then finally started working normally...probably incorrect stock rom or seriously old...got the one from samsung-updates and that works flawlessly
i have a samsung galaxy s3, ive been rooted for a long time and flashing roms all the time. well i flashed a rom just now and i have no signal, not sure if i burned out the radio (not sure if thats possible, but it also said to insert sim card while it was already inserted), but i dont understand how that would happen. the sim card works in another phone that im using now, so its not the sim card thats causing the issue. my carrier is at&t, and no signal showing, not data or cell (wifi still works, but thats a different story). has anyone experienced this and know how to fix it? im guessing modem flashing, but not entirely sure. can someone please point me in the right direction? Thanks in advance!

I believe you need to do a factory reset. Backup your data first!
Sent from my SGH-T999 using XDA Premium 4 mobile app
The first thing to troubleshoot you should do is flash back to a rooted stock rom and make sure the data is working there. If so this will rule out any sort of hardware problem. You didn't say whether or not you did but you can also try fully wiping the phone (dalvik/cache, system, and data), re-download the rom incase you had a bad one the first time and reflash. Other than that check that maybe check the apn settings.
Yup I ended up doing that last night..im back on the stock root injected rom. So im still rooted and network now works! So im glad. How would I flash a rom without losing the network this time?

Now that you have flashed back to stock a full wipe has been done in the process. At this point all you can do is flash it and see, but as i said i would redownload if you plan on using whatever rom it was you mentioned in the OP. I would also do a full nandroid backup to save the pain of using odin incase it doesn't work. I imagine the problem was with lingering files/fragments from multiple flashes that were causing the problem, in any case whatever the problem happened to be it was software related.
K will do. Its just weird because the md5 matched and everything..but I will for sure download the rom and gapps again. Thanks for the tips!

well, i finally got the service to work after flashing a rom. it still remains a mystery to me tho, i used to always use the illusion rom everyday, for months. i decide to flash the same exact one but no service, i download it a couple more times and still no service after flashing about 3 or 4 times. i tried a completely different rom and the service is active. i dont understand why and cant figure out what is so different this time hah. o well, im just glad its all working now even though its with a different rom. thanks for the help guys!
ok, im back =[
i was using the carbon rom with no problems, it was working great, but just a half hour ago i was listening to music and texting (i always do this), and then phone just turned off. I tried to reboot it but it wont! it always shuts off while booting. i made it to CWM, but it turns off while in CWM. i also made it to download mode, which led me to assume that the phone is not bricked, but it doesnt stay on download mode, it just turns off randomly. i figured maybe it was battery, so i tried another, and no change! does anyone know what the issue is? i cant figure out how to keep the phone ON, or why its not staying on.
btw, i got it to boot completely just once, and it was acting up still. any ideas? please help
Thanks in advance

What is the bootloader and baseband version on the phone? Which version of stock are you flashing?
I've tried all sorts of roms, AOSP and Sense, they all stay connected to 4g for a few minutes at most after a reboot and then go back to 3g.
Everything else works fine, and my sim works good in other phones and stays on 4G.
Any idea what this could be or what is causing this?
Have you updated to the latest firmware? If your using kitkat roms, you need kitkat firmware. You can find the firmware in the second post of santods stock rom thread in development. Use the no boot.img one.

Yea I've flashed those also. Everything used to work fine until that roaming display issue. Never returned to normal for me, even tho roaming is gone.
Have you ever ruu'd back to stock and then done a factory reset from hboot? That is the only way to wipe out the network settings and force them to be updated. Worth a try i guess.

I'm not getting 4g at all on my phone. I came here to post a question and saw yours, so thought posting another thread would be pointless.
I've got NusenseSIX RC4.5 running and while the 4g icon comes on, there's no data transfer at all. I flashed the new firmware first, as instructed, and that seemed to go just fine according to the directions. But, when I swapped my sim card from my other One and waited a few minutes, even *228'ed, no data.
I got the phone already rooted and s-offed with TWRP 2.7.0.1. How do I get it back to stock to clear out the network settings? Or could it be a bad firmwware flash, so I'm screwed anyway?
EDIT: I redid everything, and just stuck with the Sense 5.5 mostly stock ROM. Data works now. Might've been firmware, might've been the ROM on my phone. Zero idea.
Is it possible to have a bad sim?
I just got a replacement device and I still cannot get 4G service for more than about 2 minutes before it switches to 3G

Sure, you can have a bad SIM, but I don't think that'd cause the drop in data transfer rate... lack of data all together, or other things not working, sure, but if you can actually catch a 4G link and then it drops to 3G, sounds more like the radios, the hardware, or just a bad coverage area. I'm no expert, though.
In case anyone was wondering, I ended up getting a new SIM and that has fixed my 4G issue. No idea what was wrong with the SIM, but anyway it sucked.
Hey guys, i'm having a bunch of connectivity issues, all revolving around cell service. WiFi works greats. First issue is that text message get sent and received sporadically(meaning sometimes i send texts and they send right away, while other times they fail and require a few resends). Second issue is incoming calls not reaching my device(doesn't even ring on my phone) and going straight to voicemail after 2 rings/outgoings calls not ringing at all. Last and hopefully least, data seems to drop or hang on upload after a few minutes of use. Now all these issues occur sporadically and at seemingly random times, but it seems like once one of these 3 issues occur, they all get triggered.
I've checked and reset APN settings and they seem correct, although instead of "Not Set" for the username, there is "none" and there is a four digit password that has been censored by *, and for Server there is one digit *.
I've called T-MO customer service and their suggestion to solving it was a Master Reset, which is essentially a Factory Reset including wiping the Internal SD card. I've yet to do this, but i have tried a regular Factory Reset from TWRP, but the issue still persists. Not sure what to do at this point, was considering ODIN'ing back to stock(4.1.1 root66 to be exact).
If it matters, I'm running Dandroid 4.1.2, with DLJA baseband and stock kernel. Sometimes rebooting or flipping airplane mode on/off fixes it for a couple more minutes.
Any insight or suggestion would be GREATLY appreciated. Thanks for taking the time to read this.
I had this problem on my Nexus 5 and it seems to be sorted out now. But I'd highly recommend ODINing to the latest stock if you change your baseband radio and you're still experiencing the same issue. (I'm also a T-Mobile customer)
Also, I recommend heading to the market and downloading Offline SIM APN Database to verify you have the entirely correct APN.
Hey, thanks for the swift reply. Firstly, i checked the offline sim database and my APN settings match those, so hopefully APN settings are out of the question. And by latest, are you referring to 4.3? Also, i don't think i've ever flashed a radio/modem of any kind, and my baseband has been DLJA since i first bought this phone ~1 year ago.
I believe so that 4.3 is latest.
Before flashing 4.3, make sure you Sim unlock the phone first.
It sounds to me like its probably one of the following causing your issues....
Bad SIM card
Network problems on T-Mobile's end
Corrupted firmware or data
Or just part of the actual hardware going bad
(Listed what I think is most likely first)
Go to a T-Mobile store and ask an employee if they can test your device with their sim, or better yet, since its random ask if they can just replace yours.
Call T-Mobile to ask if there are any known problems in your area. If not ask if they can reset your account.
Flashing firmware with Odin (not mobile odin) can help determine if it may be a hw or sw problem. I do recommend factory resetting with stock recovery though. This actually formats /data, where custom recoveries just selectively delete things.
If its still giving problems after all of the above, its a pretty good chance some piece of hw has gone bad.
Thanks the replies guys, I'll report back with some results. Just wanna add, I've tried my sister's S4 LTE Sim on my phone and the issue still seems to occur regardless.

Hey guys, i'm having a bunch of connectivity issues, all revolving around cell service. WiFi works greats. First issue is that text message get sent and received sporadically(meaning sometimes i send texts and they send right away, while other times they fail and require a few resends). Second issue is incoming calls not reaching my device(doesn't even ring on my phone) and going straight to voicemail after 2 rings/outgoings calls not ringing at all. Last and hopefully least, data seems to drop or hang on upload after a few minutes of use. Now all these issues occur sporadically and at seemingly random times, but it seems like once one of these 3 issues occur, they all get triggered.
I've checked and reset APN settings and they seem correct, although instead of "Not Set" for the username, there is "none" and there is a four digit password that has been censored by *, and for Server there is one digit *.
I've called T-MO customer service and their suggestion to solving it was a Master Reset, which is essentially a Factory Reset including wiping the Internal SD card. I've yet to do this, but i have tried a regular Factory Reset from TWRP, but the issue still persists. Not sure what to do at this point, was considering ODIN'ing back to stock(4.1.1 root66 to be exact).
If it matters, I'm running Dandroid 4.1.2, with DLJA baseband and stock kernel. Sometimes rebooting or flipping airplane mode on/off fixes it for a couple more minutes.
Any insight or suggestion would be GREATLY appreciated. Thanks for taking the time to read this.

Funny that I came across this. I was experiencing (seemingly) the exact same problem very recently. I even picked up a new SIM card, but that didn't fix it. I was beginning to fear it was hardware related. But like Doc suggested, I used ODIN to flash stock fw, and all is well again. It appears that my problem was related to data corruption. Thought I'd post to confirm returning to stock via ODIN fixed the issue for me - in case it happens to anyone else.

Thanks for the reply! Unfortunately I'm still experiencing this problem. May I ask which Android version you ODIN'd? If 4.3, MJC or NC2? I've ODIN'd two firmwares, 4.1.1 LJA and 4.1.2 MD5. I've held back on doing 4.3 because I know after that, there is no way back. But if that fixes the issue, I'm all in. Thanks!

I used UVDLJA 4.1.1, and so far I'm free of the connection issue. I feel the same as you... don't want to flash 4.3 without being able to downgrade. I picked the LJA fw because that's what my phone shipped with, and the radio/bootloader combo always worked well for me. Sorry it hasn't worked for you! Maybe a stupid question, but did you factory reset after ODIN flashing?
Out of curiosity, did the issue resurface while you were still running stock fw? Or had you changed ROMs?

Yeah, I've factory reset from the stock recovery and had everything wiped. Well first the issue initiallly surfaced on the Dandroid 4.1.2 ROM, but I had ran that ROM for close to a year without any issues, then all of a sudden it happened. I ODINd the 4.1.1 and factory reset and at first I thought it worked but a few minutes later, the problem resurfaced, so to answer your question, yeah it still happened on stock fw. I may try it again just in case I take it in to a T-Mobile store.

Well since you ruled out the SIM card already, the 2nd part I mentioned would be my next suspect. (Network problems on T-Mobile's end. )
Is there any way you can get maybe 5-10 miles away from your usual locations and test there? (Remember to reboot after making it to a new location). If its still giving problems there, its very unlikely to be a tower problem. (Still possible, but very unlikely. ) Also, call T-Mobile support and ask if they can perform a reset on your account. (Can't remember what they call it exactly, but they should be able to take some sort of similar action on your account from their end.)
Finally, if you are still running 4.1.2 or 4.1.1 firmware, you can try flashing the different modems I have in my baseband thread. (Stickied in development). I can't remember right now if the 4.3 modems will work on the older firmware, but its ok to try them all. Once you update to 4.3 you can no longer use the older modems.
If, after all of that, you still are having trouble, you can pretty much rule out network problems. It'd still be a possibility, but only a very unlikely one.
After this, you might want to seriously consider flashing the MJC firmware, then NC2 if necessary. If none of that is helping I don't think there will be much more you can really do....
