Hello,
I'll start from the beginning so maybe someone can figure out exactly whats going on with my Galaxy S4.
So my carrier is Telus and I had just a rooted 4.2.2 and everything has been fine since day 1 of rooting. 2 nights ago I noticed the stock Google Edition ROM was out and I decided to give that a try. I flash the 4.3 Google Edition ROM which said Canada (Bell/Telus/Rogers) and I was using that for about 24 hours. Everything was great, however I noticed I lost my 4G/LTE connection. So without being connected to WiFi I had no data plan basically, everything was on, carrier was selected all the APN settings were correct so I was lost. Completely confused as to why this is happening I just decided to restore to stock, unroot and start from scratch. I used Oden to restore the stock ROM from Telus back to android 4.2.2
Now, once that came back, still the same problem and what I noticed was it installed all the Bell Mobility stock software and when I plug the phone into Kies it's listed as a Bell Mobility device. How is this possible? I used the Telus stock ROM to restore, once that I've used before without any issues at all.
Any help would be appreciated, if you have any questions let me know.
Thanks.

I'm wondering if the 4.3 rom managed to update your EFS or CSC data... I'm no expert in these areas (and I'm on AT&T), so I don't think I can be much of a help. But this might be something to look into. Also be sure you wiped data too (you didn't mention it).
Also, I'm wondering if you have the correct Odin file for your carrier (if there is such a thing as a difference?)? I know with older handsets, it was possible for AT&T to push out APN settings, etc. from the carrier's end, forcing updates to your handset. Not sure if that's still possible or not.
If you have a nandroid backup of your ESN partition, you might try to restore that. Don't try to restore someone else's backup, or you'll mess up your IMEI and such.

Yeah sorry I forgot to mention some stuff. I have wiped data and factory restored before flashing the stock ROM in Odin as well as wiped everything again as soon as its complete. Right when it boots up the APN info is all wrong. I have data now if I set it up myself but its just sitting on H+ rather than LTE/4G. Also it seems to install the Bell bloatware rather than the Telus bloatware, so something within the phone still thinks its a Bell phone. I'm stumped, so is the Telus guy who was trying to help me with it today. I know I'm using the right .tar stock file from Telus because I've used it before. Man this really stinks!
EDIT: I'm not sure if this is valuable info to add but I just noticed when doing a factory reset it says the CSC that's applied and its labelled as BMC which is Bell Mobility. This is a Telus phone so I'm assuming my problem is somewhere right from there.
ALRIGHT!
I fixed it... I found a tutorial on how to change the CSC with the key command
"*#272*Device IMEI#"
Then it showed a list of carriers and I chose the right one, rebooted and it restored everything and presto. 4G/LTE is back on.

Hi guys been searching all day when I can grab some free WiFi, basically I rooted my s4 gti9505 with auto root and then installed custom recovery, and flashed PAC rom. I'm unable to make calls or receive mobile data but can use WiFi. My settings say baseband unknown .. I'll attach a picture of my settings here in this thread. I have attempted to flash a modem/radio in Odin but this didn't seem to make any difference, the problem is I'm not sure if it was the right thing to do (didn't make a back up of my phone foolishly before flashing PAC rom)
I'd appreciate any help with this guys! My network is vodaphone UK if that makes any difference to any advice given...
Thanks in advance!

will do this too, have just finished flashing MGA modem twice using your steps, will flash rom again..i wonder if i should wipe/factory wipe as i would when installing new rom...ill try it!
no luck -still no network. im running out of ideas
network - unknown
mobile network type - unknown
imei unknown
imei sv - unknown
going out now for a while but thought id ask - do you think that installing official stock rom (perhaps from your s4 unrooting guide) would help flashed via odin? from searching i can see that some folk suggest that stock will reinstall everything i need...im hoping so, i really wouldnt mind going back to stock, anythings better than this

did you put modem in "phone" in odin?
hmmm weird! i guess your imei is not corrupted, sometimes while flashing rom in cwm, efs partition is not detected, so flashing modem twice should work
you can try with an other modem, use new one (but im sure to flash it twice)
another option is trying to flash your stock firmware

yes put it in "phone" mode, thats the second or third one i have flashed now so im not sure it wont help but for sure ill try again!
are you able to determine that its not corrupted? would it state as such if it were? im going to flash a stock firmware as a last resort. lost after that haha
edit - installed cwm using sgs4 flasher and re-installed my custom rom and gapps, booted no probs and network now working - sorted!! thanks for your help i dont think i would have reflashed the rom without your advice to do so
So I'm practically in the same boat. I'm currently on P.A.C. man nightly 09/18 (Vodafone Germany branded device). I never had similar problems, but now I can't call (or be called) and I'm not able to use mobile data.
I nearly tried everything:
1) I checked the IMEI (saved it before switching over to custom roms), but an IMEI number is still there.
2) Went back to stock to see if it's a problem of P.A.C. man ROMS or not. On stock it didn't work either.
3) Went back to P.A.C. man ROM and flashed modem XXUBMF8 via Odin 3.04 (from this thread: http://forum.xda-developers.com/showthread.php?t=2192025)
4) Flashed the modem again after I flashed the ROM because it didn't work either.
So I'm completely lost now, I really don't know what to do next. I had mobile data for a couple of seconds every now and then, but nothing stable. And since the problem came up (yesterday evening) I can not make any calls at all.
Can someone help me?
Edit: The very strange thing is that I have full reception balks in the notification area (only in grey). But still, I guess this means that the device is somehow able to detect a signal but can not connect to it?
Edit2: I apparently have no Device-ID. May that be a problem?
So I took some screenshots to show you guys my problem a bit better. For some reason my mobile data now works (currently HSPA, but it's extremely slow). But I still can't make any calls (or get called too). =/
Edit: So to sum this up: the strangest thing about this problem is, that even when I go back to full stock I can't make calls. =/ What could be the problem? An IMEI number is present in the settings (althouh the 'IMEI SV' under 'About phone' --> 'Status' was one digit below the current one that I can see under those stats). The whole problem makes me believe that my provider can't sort my phone number to my device (I'm on Vodafone; but if that's really the case: why the hell does mobile data works sometimes?!). The other possibility: something with the modem/radio is broken. Could this be the problem? The thing is that I also tried to flash a custom modem, but the problem is still there...
I'm really concerned that my phone just became an expensive paperweight
Slightly different than my problem in that I didn't even have any bars for reception..my problem was fixed by changing the custom recovery software (originally I used philz to flash PAC), But I flashed cwm and then used this to again flash PAC, and all was good..don't ask my why but it helped me so you might want to try this...

Thank you for your answer!
You also flashed a different modem didn't you? Did this help or was it only the custom recovery? I'm confused because I used CWM before and never had problems. But then this mess all came up...
Yes I flashed several modems, that didn't help..only using a different custom recovery to flash my custom Rom again helped..hope you get sorted!

So I tried to flash PAC with TWRP 2.6.0 (it worked before), but the problem is still there.
I'm really confused. I really don't know what I can do or try to fix this mess... Is there some USSD code or something to find out if my device is missing some ID codes or if the modem is messed up or something?
Edit:
Update: For some reason I now can receive calls/SMS but only when I'm on GPRS speed. Outgoing and ingoing calls are no problem then. When my device is on HSPA or HSPA+ speed however, the old problem of not being able to call or be called is back. On one hand it's good that I'm somehow able to make calls again on the other hand it gets stranger and stranger. I know that it's a bug on PAC man ROMs that you can't change the mobile data speed options (LTE/HSPA/GPRS etc.), but I think that this could be the problem (or at least a part of it)...

Actually I can change the data in my phone between 3G and 2G (don't have LTE support here in my country)
Have you checked your APN? Think that might be a problem.
Also please post the steps you take before flashing PAC (ROM, kernel, recovery, etc)

Within Wireless & Networks --> Mobile Networks --> Network Mode? On PAC? It always crashes when I try to change something there. In the PAC bug post this seems to be a known bug, my mode is also set to GSM/WCDMA/LTE. But whenever I enter the settings to change this, only 'LTE' is chosen as option. I don't have LTE on my plan and I read somewhere else that Vodafone has major problems with it's LTE network here in Germany and that it may be better for customers without it to turn it off.
About APN: there is definitely something strange. I can enter the settings and I see three different APNs that were not created by me (they must be the standard carrier ones): they are called Vodafone DE (for Germany), 1und1 (pretty strange because the settings are the very same on this one, only the name is different) and Vodafone DE-MMS.
The strange thing now is that I can't change any value of the Vodafone DE APN... When I go into its settings, everything ia greyed out. This was the same on the stock ROM...
Now when I create a new APN with the correct provider settings (found via Google on the VF homepage), the phone still won't work. When I put the device aside for a few minutes, the Vodafone Deutschland DE APN is the selected APN again although I never went back to it...
Is there some option to take a deeper look into the modem stats to see what's the problem?
Install stock ROM

I tried that already, but it didn't help. Same problem...
I factory resetted the phone, wiped cache and dalvik cache and then flashed my Vodafone branded stock ROM via Odin that I had on my device when I got it. Didn't help for some reason... But: should I also try to go back to stock ROM via KIES? I haven't tried this method until now...
Edit: About my flashing method: I went from the stock ROM to rooted (via CF Auto root with Odin). For PAC I then flashed TWRP 2.6.0 and then in recovery factory resetted the phone, wiped cache and dalvik and then installed PAC. After that I installed GApps. I used this method before and it worked without any problems...
Edit2: I found this thread, it appears to be the same/a similar problem with the S3: http://forum.xda-developers.com/showthread.php?t=1805709&page=6
Now is there something similar for the S4? I think I tried calling ##72786# on stock ROM and it didn't work...

Delete the unused APNs.
Do you have mobile data?
Also I asume that you're running the latest vertigo's build, because with me GSM/WCDMA/LTE is always selected.

Sometimes I have mobile data, but only for very limited time; for the majority of time, I don't have mobile data and can not make calls.
I also tried to delete the unused APNs, but still no change =/
I tried to use a different Micro SIM in this device, but the same problem appears. No data, no phone although I have grey reception balks.
any update on this one?!
I had an issue with Alliance rom. It went from wifi to 4g and I lost the prl and other stuff (said unknown). I only had wifi.
I was able to Odin back to stock. It took like three times as it would not move past the activation screen.
Now, on stock, I flashed TWRP recovering using ODIN, then used the CF root from Odin also. Phone restarted and while I have the 4g logo, I have no phone and the information is missing again (PRL). I do get wifi.
I just used Odin to reflash stock and it is still doing it. I also used the imei tool to restore what I had backed up (EFS). Can anyone help? What is going wrong?
Edit: Phone restarted with root BUT now I cannot make calls (it says roaming) and I am missing the prl and other things again. HOWEVER, I can use wifi, and 4g and no texting also.
If anyone has a clue I'd like to know, thanks.

I actually could not find the stock modem. I DID solve it.
1.) Odin back to stock. It will freeze on the activation screen.
2.) Remove sim card after shutting down.
3.) It will get past that and connect with wifi.
4.) THEN clock on roaming to turn it on with sim in.
5.) Phone will then contact US Cellular to "activate and program." It will finish after a few minutes.
6.) Restart and enjoy
In case this happens to anyone else. Thanks for the help (lol). I've had a Droid Eris, HTC DNA, and a Droid Bionic.
Hello community, I searched for hours before actually posting this thread.
My device: Canadian SM-G900W8(klte)
Last stock firmware: G900W8VLU1BOC1
Carrier: Rogers
Recovery: TWRP 2.8.7.0
Two days ago, I flashed the CyanogenMod 2015-07-14 nightly build on my phone using the official guides including gapps and everything seemed to work perfectly except one thing: the phone can't connect to the cellular data service but calling and texting does work, only internet dosen't it won't connect to the 3G/4G/LTE at all.
Before flashing I of course backed up everything with TWRP including my EFS/MODEM partitions so I switched back to my stock nandroid backup because I really needed my fully working phone the next day and it was late and data worked again.
Today I gave it another shot with the 2015-07-16 nightly and the same problem is there... I verified my APN settings and everything is correct. When I first got into the APN menu there were alot of them on the list including the ones I had on my stock ROM but none was selected so I ticked the one I had before but it still dosent work, I tried all of them on the list and no result. I even verified the APN(s) exact settings with my Carrier and everything was good yet the phone still won't connect to LTE, but calls and text do work again... Another thing I did was to restore the modem/efs partition with TWRP while running cyanogen just to be sure but it didint have any effect.
I really wanna use CM because I'm disgusted and tired of TouchWiz but I'm clueless on how to make the data work I tried everything I knew and read on forums.
I have the exact same issue...same phone, same network....
Did you resolve this?

Try to delete All Useless APN setting. It resolve my problem, and I have the almost the same configuration. ( Rogers, S5, Cyanogenmod 2015-08-01 )
The only one problem that i got, sometime LTE network lost signal for 10-30 seconds. But for what I read, it a common issue with this version ( 5.1.1 )
Good Luck !
Tried all that....
Finally went to an earlier build from April....working good now!

Thanks for the suggestion. That fixed it for me, as well. I actually deleted all the APN settings and then recreated Rogers LTE (ltemobile.apn).

So I have been using MetroPCS on my Moto G5 Plus since I got it. Well today I went and activated my device with the Sprint network... It wasn't working when I left the store, and I told the rep how it was modified (using RessurectionRemix 5.8.4 Final), that I would work on setting it up.
Well, so far no success in activating it... Have tried changing network mode to CDMA/LTE and messing around with dialer codes, still can't get anything besides "emergency calls only."
Anyone have experienced getting this phone activated with Sprint?
Note: they did tell me they didn't have the exact, or "recommended," SIM card for my device, and that it was a secondary option they used in the system(?).

I am using that SIM, got it working when I reflashed stock. Did not work again when I restored RR, at least fully, as I was able to get data to work minus SMS/calls.
I'm on Sprint. No issues with any Roms.
You need to be on a stock build for the initial setup, because the custom roms remove all of the PRL stuff. Once it is setup once, flash whatever you want.

It doesn't stick after I flash a custom ROM
That's really odd. I don't have that problem...
Make sure you have APNs on the custom rom. I saw a problem a while back that the custom rom didn't keep the APN for some reason, and I had to put it in manually. Different device, but same problem.

Can you tell me what your APN info is? I have data and calling working now, but no LTE option (see screenshot)
I have mine set to global.
I had this same issue with my s6, and I ended up having to factory reset the phone, and redoing the PRL update, and the option finally came back.
Just to follow up, I was able to get full LTE and calls to work by flashing stock ROM, updating PRL, and by then it was provisioned on the Sprint network.
As it stands now, if I reinsert my MetroPCS sim card, it is provisioned for MetroPCS no problem, but I do have to reflash stock again each time I want to provision for Sprint.
So thats how I am going to run things for now, by making backups and getting it provisioned using stock before restoring.
this worked for me

theres an ap on the play store called apn backup and restore. install it on stock rom . b4 using it u need to go in system/apps and move the apk to system/priv/apps once moved changed permissions to r-w-r-r. after that a quick reboot and open app change setting to disable ics check and do a backup . once finished do the same thing on new rom and mine works flawlessly. im on boost which is also on sprint network. good luck hope this helps
So, I was fed up with the fact that I couldn't use 4G band 20 on my sim free purchased galaxy s8 in the UK as my signal is poor in my local area and without that, would leave me without any signal at home so I successfully managed to flash the Three software and then it was easy enough to enable it - still no VOLTE option of course!
However my GPS doesn't seem to be accurate, feeezes and when I went on holiday to the USA air wouldn't let me manually select my network, but my wife's phone that is on the standard firmware allowed manual network selection. I didn't have these issues when I was last in the USA In September
As I say, I mainly changed so I could somehow enable Band Wp 4G, however I've now managed to do that on my wife's phone without flashing new firmware, so I'd like to revert back to standard unbranded firmware.
When I changed to three software, I ran google backup, Samsung backup and used Samsung smart switch backup as well and it didn't seem to back everything up at all. I had to resign in two absolutely everything, redownload items, lost my reminders, lost my notes. Is there a way to do a complete full backup and restore so I can go to unbranded firmware?
Thank you
Any ideas please?

Not unless you're rooted. You can try helium but again no guarantee.
