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.

Well he says he's got the Hercules, it's the exact same phone I'm using I think, I hope he gets on and checks the link out, cuz it worked first try for me, I hope to share the satisfaction of solving this very frustrating problem.

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 have spent countless hours restoring the stock firmware, re-rooting, updating, and even replacing the SIM in order to figure out why out of the blue during a simple reboot my S3 decided not to communicate with anything but Edge and an ocasional call. The IMEI was set to zero and now is reset (using QPST) and the phone is talking to the network just fine (according to several senior level support techs!). WIFI is working. The modem signal strength is weak.
d2att_I747UCUEMJB_modem
I am back to running @PwnCakes193 4.4.2 Quantum ROM and I am at a loss! No LTE, 3G, and poor signal quality.
ANY help would be greatly appreciated! I have been flashing ROMS and android devices for YEARS and never have I been so stumped!

I am having the same issues after flashing Validus 5.0 RC1 (Kitkat 4.4.2) I am back on CM 10.2.1 now and it has been holding signal, but it still drops occasionally. I was wondering about flashing back to stock and re-rooting re-flashing.. But, not sure if a) that will work b) which stock to flash back to (I originally rooted from 4.1.2 if I remember correctly
my device now: i9195, I9195XXUCNE6-DBT
I experience weak signal and many connection dropdowns. When this occured first, after i upgraded f4ktion Kernel 1.3.6 to 1.4.5 and
an older version of Carbon Rom (4.2.2) to 4.3 Carbon Rom. Until than everything was fine, flash of rom and kernel did not made any problem.
Btw i used Odin3 3.09 and clean install (step by step like in the guides) all the time.
After some days this realy annoyed me, so i went back to the older Carbon and kernel - problem still occurs.
So i went back to stock rom I9195XXUBML4-DBT (original was UBML4) - problem still existing.
Some time later f4ktion 1.5 and Carbon 4.4.4 was available, so i tried this..still no solution.
Now i am back to stock and updated to I9195XXUCNE6-DBT, same problem.
Some research told me many ne stuff to know..like flashing modem only. I tried some, nothing helped.
After hours of pointless googleing i noticed something on my phone.When i dont type the pin, i have normal signal. As soon as i type the pin
and "activate" my simcard, the signal strength drops. So i googled again and found this:
[Bug Watch] Android 4.3 Radio Bugs Causing Cell Connection Drops On Some Nexus 4 Handsets, Fixes In Sight (not allowed to post links)
I changed the network type to WCDMA only - it helped for some minutes(not many..maybe 2-3). I changed to GSM only and i had normal,
stable signal for like an hour. But later signal loses strenght again, and i need to change network type again.
I have the feeling, that its like a reset or restart of the radio.
But now i am all out of ideas and need some help.
Last thing i can do, is to bring it to repair. But my Knox says 0x1, so maybe you can help me before i ask Samsung.
I have similar problem since ugrading to KitKat roms. I had no problems with previous none Knox roms with MH3 modem but now with NE6 and NF7 KK modems the signal swings constantly up and down from 4 to 1 bars. This is in areas I previously had good signal. Internet also keeps dropping out requiring data toggling on and off. I've reflashed KK 20+ times and haven't been able to get rid of this problem yet.
I'm not sure if pre knox modems are installable but I intend to try and reflash MH3 modem, once I manage to do a successful backup.
I solved a similar problem by downgrade to 4.2.2 Brazil NE2, knox 2. Flashing separate modem (NE2), and reflashing full rom again. No problems for now
Now you stay on 4.2.2 ?
I dont understand why some people do have problems and some not. Is there different hardware version causing the trouble ?
Give me pls some information how you did the downgrade.
-Nandroid Backup
-philz
-Odin (if yes which version)
-why did you choose that rom
I tried to, but wasnt succesfull. I used Odin3 3.09 to flash 4.2.2 (UAMF5 i think) rom and got a brick. When trying to fix this nothing helped until i tried to flash with Odin3 3.04. But all i could do was flashing newest FW again. Did not test more after that, because i was very busy.
If you say that going back solved your problem, i will try again go go back myself. I've found some information on that and when its done i give some informations.
Same here, help?
I'm having the same problem with a newly acquired handset. I have full signal on some places and nothing on others, unfortunately in my house I have no signal! So it's quite exasperating.
My baseband version is I9195XXUCNE6
Android version is 5.0.2 with 3.4.0-cyanogenmod-g92aec50 [email protected] #1 kernel
Cyanogenmod version is 12-20150306-UNOFFICIAL-serranoltexx
Would it help if I flash a separate modem file through Odin? In that case, which one should I flash?
Any help would be appreciated a lot.
Thanks

If you have warrenty left then you should go to customer service then they will change your mainboard. and it would bw okay.
I've got the T-Mobile M919 S4 and I have a 4.4.4 ROM on it (Insane Hybrid).
I've got the latest NK2 Baseband and I also don't want to upgrade to Lollipop since I did before and it was lag lag lag lag lag after a week or so.
I've noticed recently that it is getting very poor reception.
My buddy's S3 will have two bars and mine will show no service. Or it'll have bars but no data service. Or I won't be able to call out.
There also seems to be an unusual amount of spots where I have no service.
When I do have service, the data can get really really slow.
My GPS lock also frequently gets lost during navigation.
Any ideas? Do I need to flash a kernal, modem, or radio or something? Which ones?

Try updating your baseband. That sometimes solves it. Here's the link:

Thanks, I'll give those a shot. I'm going to flash this and see what happens:
http://forum.xda-developers.com/gal...stock-base-4-4-4-nk2-rooted-deodexed-t2990478
I'm still a bit confused on some of the terminology and what's bundled with what.
- The "modem" is the same as the "radio", right? It's a driver that controls how the device deals with cellular voice and data signals. I can find the version of my modem/radio by looking at the last letters in my "baseband."
- The modem/radio driver is usually bundled with a ROM, right? So the ROM that I flashed above will also update/replace my current modem/radio driver?
- Modem/radio drivers can be separate from the ROM itself. If I use a 4.4.4 rom that has NK2 bundled, I can still flash just a NH4 radio using ODIN onto the old ROM and be ok, right?
- Where does the kernal come in? I'm assuming the kernel is bundled with the ROM and the kernal is only in charge of the switching between cellular and WiFi data, right?
That's the price you pay with custom roms, sometimes your lucky and everything works the way it's supposed to sometimes it doesn't.
Run phone for a day and make sure everything works properly after flashing back to stock before attempting custom again.
If you need your device to function as a reliable phone, making and receiving calls and messages you may have to rely on stock roms.

This. Would anyone please answer the above questions above as I am also looking for some answers to the questions above?
Hi,
I have been facing problem of not getting 4G LTE network on my One Plus 5T. And after a while I realised that it's after the latest OS update of OOS 5.0.3. I am in a full 4G network area and my sim is also working fine when I put it into different phone. So I know for sure that it is not a problem of Network or Sim as both are working fine. I have also searched on google abt the same and lot of people are facing the same problem however I could not find any fix or resolution for the same. I have tried clearing the cache from the recovery but no help, also I have selected LTE only thru *#*#4636#*#* but still no help. Any help would be really appreciated. Thanks.
I'm assuming your APN name is correct?
It seems like almost all problems with Oreo updates are caused by dirty flashes. Typically a clean install fixes everything.
If you didn't do a clean install that's step one.
Solved, go to read my tread
Hello
For information:
On ROM O+ 9.0.4, the 4G hook works better on the "Global auto (PRL)" parameter.
