[Q] Please Help. Very strange problem with my phone.

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.

GT-i9505 No mobile network/data after flashing custom ROM

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.
Sent from my GT-I9505 using Tapatalk 4

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?!

try reflashing stock rom unrooted and it should come back. it may have to do with the gsm unlock you did but reverting to stock and then rerooting should fix it for ya.

@Andr3s - you did allow the sprint updates to run after you rooted (or installed the current ROM), right?
If the sprint updates don't run, the hotspot won't show up.

Hi, I had the finished version in AMF9, I did downgrade the modem to MDC to unlock and work in GSM mode, then went back to update the modem to AMF9, I root the phone and the next day the phone using the option disappeared and I have the latest version of Sprint.

You wrote AMF9 twice, so I assume that is not a typo. The latest Sprint update is MF9 - you are on MF9, right?
Did you install the hotspot mod? If so, when? were you on MDC modem? or MF9 modem? (which mod did you flash?)

Hello This was what I did
1 - updating my phone to version MF9.
2 - Flash MDC Modem version
3 - Run the unlock to work on GSM
4 - I returned back to making flash MF9
5 - I did the root of MF9
6 - Install all my apps and when I looked at the option of the option links Hotspot disappeared, and when I install any of these tethering app says "Hotspot not Supported". but the strange thing is that before if it worked.
Also install the Hotspot Modem, both odexed and deodexed dome and nothing.

You indicated that it worked before - do you mean - before step 1 in your list?
Here's my understanding of how this should happen. When you wiped your phone, and installed the new ROM/modem/etc, the phone should do a handsfree activation with Sprint when you first boot up. If this activation is skipped, the hotspot (and the sprint bloatware) doesn't get installed.
Sorry if I'm being confusing - hope this helps.

A it should have been that, I do not turn the phone on Sprint, since I'm outside the United States, that hurts.

software unlock

I did the software unlock via the dial code & UMTS menu, I can make phone calls with a different carrier sim, but I cannot get the data to connect. I have been searching xda and google for months trying to get this to work. I have a Canadian Bell mobilty i337m. Stock rom (mdj) and its rooted. I have tried factory reset several times but it doesnt fix it. I also tried flashing back to stock with odin. Does anyone have any other ideas?
When I try a telus (or other provider) sim, it give me voice service only and in the about > status menu the mobile network state either says disconnected or connecting. I have the data toggle on also.

Those unlocks don't work that well with the Canadian variants. They're designed for the i337 not the i337m.

Have you made sure the apn is set up right for the carrier?

Maybe this will help
Code:
http://apn-settings.com/canada/apn-settings-bell-mobility/

I will say the reason that cause the problem is that this is an ATT phone with At stock ROM. So it doesn't have the APN setting for other carries. You should set that by yourself.

Not true. I successfully unlocked my first S4 I337M on Bell following this tutorial. I sold that one because I was able to make a profit once I unlocked and flashed the AWS mod to make it compatible with WIND and Mobilicity.

Try reflashing the original 4.2.2 firmware from here and then immediately follow this tutorial before rooting (do not install any system updates!). Then you can root, install custom recovery, reset the flash count, etc.

All questions and help issues go in Q&A and Help section

Also, ive manually inputed apns for telus and eastlink and neither seem to work. I can always make voice calls, but the data will not connect.

I will say the reason that cause the problem is that this is an ATT phone with At stock ROM. So it doesn't have the APN setting for other carries. You should set that by yourself.

oddly enough, when I put a telus sim in it and waited for a while (in hopes it would eventually connect to data) and the apn settings for telus were in the phone. I know I didnt put them there because the apn settings for koodo were also present along with a third apn that I cant remember.

For future reference, try not to double post. Just edit your current post.

It's actually not an odd thing to happen. Once an activated SIM is inserted and the phone is unlocked, the phone searches for the best APN settings from all compatible carrier bundles. Some phones do this more accurately than others. However, it may not do this well enough if a custom ROM is installed. I know this to be true because this happened with my older Galaxy S3 when I tried selling it to someone (it was a T-Mobile unlocked running CM 10.0 at the time). However, setting the APN manually (assuming all settings are correct and that nothing else is wrong with the phone) should resolve your issues.
If you're still having problems, I suggest doing these things:
1. Try going into your network operators and let the phone search for carriers nearby. Once the list shows up, tap on Telus and wait until that screen closes on its own.
2. If you can't get data going yet, try disabling it, re-enabling, and reboot.
3. If this still doesn't work, try going into the network mode screen and select GSM/LTE and reboot.
4. If it's still derping on you, then it must either be your SIM not connecting to Telus's data network, or your account has a data block. That's all I can really think of.
Good luck.

Ok, reflashed stock 4.2.2 (the first one) and manually entered TELUS apn settings from the telus website, got data to connect finally. As a note, there was a typo in the apn settings that it auto aquired for telus. Going to try a eastlink sim tomorrow and hopefully AWS is working.
Edit: all seems to work. thanks everyone!!

Sprint users?

Are there any fellow Sprint users on the MXPE? If you are, are you running an AOSP ROM? Have you ever gotten data and voice roaming working on AOSP? If so, how'd you do it?

Yes, I've had data working on the orion rom (which I believe is cm13 based). Check your apn's, the one containing n5......something.or.other is the appropriate one IIRC.
Mobile networks should be cdma/lte.

Network data and voice is just fine for me. It's all roaming that's messed up. Will check apn's next time I flash.

I must be blind, but where do we find the APN settings on the phone?

^^It's a byproduct of "stock" software. APN's access is readily available in aosp/non stock roms.
The function is still there in the stock rom, but requires an extra step or two to get at it.
If you use a third party launcher such as nova, you can add it under activities. Long press a blank area on the home screen, select widgets, then swipe to the left on the top most row, select activities. Scroll down and open the settings entry then look for APN.
Or, use this - https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher&hl=en

I'm on Sprint with STOCK/LOCKED/UNROOTED and this phone flat out refuses to roam all over the US. Specifically what APNs should be in the STOCK list (I used Nova to access APNs) and they look to be there.

^^I don't think the apn has anything to do with roaming. Have you checked your roaming options under the main android settings?
Are you on a plan that provides roaming? Roaming properly enabled on your account? Updated the prl?

I drive semi truck, my usual run is Wisconsin to Washington state and back. My phone, for the most part, will switch into roaming using TruPure. Two runs ago my phone wouldn't roam at all. I tried toggling data, updating PRL and the device config, eventually doing a clean flash, and still had no roaming. Eventually I ran the stock restore tool, flashed the modem separately, and did *#*#72786#*#* in the dialer. I'm back to roaming on a stock based ROM again. I haven't tried an AOSP rom since posting my question a few days ago.

^^Did you post about this in the rom thread? I'd guess one of the removed services is somehow affecting roaming.

I wanted to do a bit more trouble shooting first. Before my next to Washington, my plan was to flash AOSP and see if roaming was working again. I forgot to note, after confirming roaming was working on the stock ROM again, TruPure was flashed and was roaming properly too. My thoughts were that somehow Sprint provisioning got screwed up or a flash somehow messed up the modem.

When you flashed truepure again, what type of reset did you do (if any)?
Sprint's provisioning system is poop. Their system is a 2 part authentication. Your voice/text is tied to the device meid (not imei), data is tied to the sim card. This seems quite @ssbackward to me, considering verizon, tmo, att all associated your number with the sim card. While the device still transmits its imei during registration, no user intervention is needed when switching device. With sprint you need to log into the account and update the device too.
It seems each time you do a clean flash (wipe userdata), the software attempt to perform the 'handsfree' activation (or its equivalent on the moto x). If you perform a factory reset from within android, a number of carrier parameters get erased. If you a factory reset from twrp, they get retained.
I'm also on sprint but through ringplus, so no roaming included.

After running the http://forum.xda-developers.com/showthread.php?t=3199905
[WINDOWS TOOL][5.1.1]Moto X Style/Pure Edition "Restore-To-Stock-Tool" , flashing the modem separately, and doing the dialer codes, all was good with roaming. Roaming again worked with TruPure. Nothing special was needed. After restoring stock and reflashing TWRP, I just flashed TruPure like any other rom. No special steps were needed.

Sorry for the long delay, been all over the place.
Yes plan provides roaming, and is enabled. PRL updated. I verified with Sprint customer care that the account is provisioned with no errors so I should be good to go on the Sprint side.
Im going to try what Misfit0313 did, restore to stock and flash modem. I'm assuming the return to stock takes it back to Lollipop so I'll get the MM OTA. Are you able to flash a modem on MM? Maybe the Modem side got corrupted somehow on my stock phone when it upgraded to MM right out of the box.

Buried in the Restore to Stock tool thread, there are directions to flash the modem separately via ADB. For some reason, the tool broke WiFi, necessitating the need for the modem reflash.
I just took the OTA to come from LP to MM

I flashed this fix on a clean install and AOSP roaming is working.

So roaming is controlled by the apn?? Interesting. Didn't realize that was the case.
Are you the same misfit on the freenode network/evo4g lte days?

Dude, yep its me. I don't stop in there too much anymore. Always bs going on in my life. Hobbit problems.
I tried to change APN settings as you suggested in AICP rom, but I kept getting a message like 'user doesn't have sufficient privileges to change settings'. That's why i gave that old ass fix a try. Reported in AICP thread. Went to south TX this week and I have no issues to report with voice or data roaming on AICP.
Still have the Infinity or did you move onto something badder?

i can't set APNs or even make calls/texts on AOSP ROMs like Dirty Unicorn and PureNexis with Sprint...Flashing this zip fixed that for you?
Edit: Meh...just tried clean flashing PureNexis with the sprint.zip fix and still cant make calls or set APN's

My question: Is roaming working on stock based roms for you?
Stock roaming wasn't working for me, and Sprint insisted it wasn't at their end. After doing all the steps I mentioned previously, stock roaming finally was a go. I still had to flash the sprint.zip on a clean install to get AOSP roaming working. Without roaming on stock, there's no way roaming will work on any other ROM.
