I recently flashed CM10 as well as a JB modem. I decided to switch back to stock the same day, so I just restored the backup I made. I'm back to the way I was before, with one exception. Wifi doesn't work. I have it turned on, and it can find networks, but when I tell it to connect, it just basically ignores my request, telling me the network is saved. I've tried on two networks, one password protected, the other open. Same result on both. I think this may be because of the modem I flashed. A few questions:
- By restoring my stock ROM, did I flash my old modem overtop the JB one? I don't think so, just making sure. If not, that means the only thing that has changed is the modem.
- I want to make sure I'm diagnosing this correctly. Does wiFi behaviour have anything at all to do with the modem?
- If so, Where do I get a stock modem to flash? I think that should be the first thing I try.
- Where can I go to see what modem version I have? I looked all throughout the hidden menu and couldn't find it.
- Is there a place I can do a wifi test? It seems like that's the only thing I couldn't find in the hidden menu.

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.

Still no radio, will try your way, thanks!
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.

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.

i got a rooted s3 and i like to flash roms. i recently flashed dandroid but i went back to stock by odin. originally my icon is H+ but after i used stock firmware from sammobile ( i got an unlocked, non carrier version s3) the icon became 4g. i notice since then my speed has been worse because its really unstable, the signal doesnt drop but it never connects. I mean like those tiny arrows that tell you if theres any data moving dont do anything. Even using a lightweight browser like opera mini is slow now. Is there ny way to go back to before? btw i already tried reflashed and wiped data.
Have you tried a different modem?

Stock rom shows 4GLTE no matter what you are getting. Go to the "about phone" and look for the current data type. For me it says LTE:13 or something to that extent.
A word of caution, cause it just happened to me. Be sure to backup you IMEI if you haven't done so and put it in a safe place, or two! I don't think you have this problem now. In settings-about your IMEI would be 0. I had a backup but freaking lost it somehow and had to get a new phone. I could not get data even though my arrows were moving as well, but it only showed E and G networks. The list of modems is in the Sticky and there is no better one. It depends on your area. Have you checked your APNs? Sometimes you have to enter or reenter them manually. There are tools to back them up. Its in the settings-more-mobile-access point names. The newest one i believe is titled phone. might say pta as well.
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.

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.
Hi. I have a Sprint Samsung Note 4. I was getting a screen overlay error and decided now would be the time to change the ROM on the Note.
I followed the steps from "How to Install CyanogenMod on the Samsung Galaxy Note 4 Sprint ("trltespr")"
After I installed the first ROM, which was the latest nightly, and booted it up, I noticed that the WIFI says "Turning on" but doesn't ever turn on. It's greyed out in settings as well. I tried a few different nightly's thinking it was a defective file or bad install. Still no fix.
So then I went http://www.grantbarker.com/samsung-galaxy-note-4.html to try different roms, and I get the exact same issue.
Now I'm thinking that there is something I'm missing that the original ROM had. And for some reason the backup I made from it is missing, so I can't go back to it either. Is there a way to fix the wifi? It kind of sucks without it. Thanks for any advice that could help.
Were you on Marshmallow or Lollipop stock? Sounds like you have the wrong bootloader and that may be the reason. You would either have to flash the recommended stock tar or bootloader or bootloader and baseband.
I don't keep up with CM but the thing to check for is recommended bootloader in OP or search the thread. You may find it necessary to flash OK1 or OG5 bootloader. Dunno, maybe check for the baseband too for CM.
There's a bootloader and baseband thread in the development forum for Sprint Note 4. You should find what you need to flash in Odin AP mode. The ones labeled firmware are bootloaders.

You could probably try reverting to the factory settings and checking if the WiFi works? And then, you could change it to the current ROM again. This might help you resolve the WiFi issue.
