[Q] Galaxy S4 (SGH-I337M) says NO MOBILE NETWORK (HELP!) - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey guys,
I'm new to the forum so please excuse me if this is the wrong place to post this. I'll start from the beginning. I bought a Galaxy S4 (SGH-I337m) from somebody in my city. They said the phone originally worked with Rogers/Fido, but that they switched the logic board on it so now it works with Bell/Virgin. The thing is though, when I put my Virgin Mobile sim card in the phone, it won't let me send texts or make calls. I checked the IMEI and it's not blacklisted or anything.
It says No Service and has the little circle with a diagonal line showing up in the notification bar and when I try to send a text, it says No Network Connection (No signal found for mobile networks). I find it weird because I still get a notification saying that I have an unheard voicemail.
I've tried resetting the phone multiple times. I've also tried flashing both the Bell and Virgin Mobile Lollipop firmwares and that didn't work either. To be honest, I'm not sure how to tell which one I would need to install. I noticed when trying to flash the Bell firmware, that the phone kinda skips to a black screen quickly every time I close an app. I'm assuming that would mean it needs the Virgin Mobile firmware.
That still doesn't fix the mobile network issue though. If anyone could help me out, I would GREATLY appreciate it!!!! Here is a bit of info, I'm hoping it helps. If you need anything else, please let me know.
Model number: SGH-I337M
Android Version: 5.0.1
Baseband Version: I337MVLUGOC4
Build Number: LRX22C.I337MVLUGOC4
Also, in the "Status" menu, I noticed it says:
Service State
Voice: Out of Service / Data: Out of Service
Not sure if that has anything to do with it or if that's normal. Again, if you have any suggestions, PLEASE let me know. I'm super desperate as I can't afford to lose the money I paid for this. Thanks in advance.
EDIT: Coincidentally my girlfriend has a Galaxy S4 of the same model and with Bell/Virgin. I opened up the ABOUT DEVICE menu in both phones and the only other difference I noticed is on hers it says:
SE for Android Status:
"sepf_sgh-I337M_5.0.1_0013"
And mine says "sepf_sgh-I337M_5.0.1_0009"
Does that have anything to do with it maybe?

Install this APP and add all screenshots pls .

Okay, will do. I will post the screenshots in about 20 mins. I rooted the phone, installed CWM and am in the middle of flashing the latest firmware again. I forgot to enable USB debugging before flashing originally and I wanted to install CWM to wipe the cache. No idea if that would make a difference but I've been up all night trying anything lol. Thank you for the reply though, will post the screenshots in about 20 mins.

Okay, I have the app installed. Which screens should I screenshot? I know you shouldn't post your IMEI online, so I'm assuming I skip the "personal" tab or?

Here is 4 of the screenshots I took (I hope this works lol)

Here are the other 2 I took

All seems correct but I think your device works for Bell Mobile (BMC) only but NOT for Virgin Mobile (VMC). Try to use one BELL simcard for verify it.

In all my experience, Bell/Virgin are always interchangeable. Same with Telus/Koodo and Rogers/Fido. I tried putting a Bell sim card in though just now and it still has the problem. It doesnt load any of the signal bars or anything. Oddly enough, when there is no sim card in the phone, the bars show up?

Since it was from Bell, would flashing the Virgin Mobile firmware somehow mess it up? What are the exact steps I would need to take to try to reset it back to stock settings? I'm wondering if I'm missing anything. Or if the APN settings have anything to do with it? I set them to default already and tried adding the Virgin Mobile Canada apn settings as well

http://forum.xda-developers.com/galaxy-s4-att is the proper place to ask your questions regarding your S4, rather than where you originally posted this, the International S4 forum. Since more people with your device will be available at the given link, you may want to ask your questions over there. Or simply be patient, as this thread will be moved over there in due time.

[Q] i337M Wifi/Network problems after flashing back to factory rom in ODIN

Can anyone Help me out here or try and lead me in the correct direction? So I tried to flash my Galaxy S4 i337M on BELL back to factory in odin. I used the I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME.tar.md5 But after flashing and booting up the phone Wi-Fi no longer works along with the phone either says "emergency calls only" or different SIM errors. I'm 100% sure the SIM works perfect I tested it in both or my other phones my Blackberry 9300 and my galaxy S3 and no problems. I have also downloaded that same bell rom from 3 different locations to see if rom downloaded incorrectly. The Phone is also rooted and has the philz_touch_5.18.2-jfltecan.tar.md5 recovery. Any help would be much appreciated.

cant say about the wifi issue, im having my own issues too..but download and flash the correct or compatible kernel for that rom .. that usually fixes sim errors or no signal
Do you have Knox issued in download mode? If so, you need to install 4.3 firmware only

Means you tripped knox. Warranty is now void, and knox itself cannot be used, which has some corporate implications, but if you dont use active sync then it doesn't matter. Now that youve done that, enjoy flashing whatever you want. Cf auto root will give you root, then id install clockworkmod myself via rom manager, and look for a rom to flash. If you wanna keep stock can use xposed to tweak.

so last night i flashed the bell 4.3 ROM and WiFi did start working. I do have signal however I'm still getting a unregistered Sim error. is there any kernel you would recommend? I'm willing to try anything at this point. I bought this phone and not more then a few days after getting it I screw my self out of using it.

If you flashed the stock rom, you'll already have the stock kernel. Did you perform factory resets after you flashed stock? You'll want to, i find it help. If you flashed back to odin with stock, and didn't unlock at some point, should auto assign apn, etc.
Can you confirm eimi and apn are correct? Did you clean flash? Wiping davlik, cache, and factory reset?

So guys i figured out my problem..... Which really sucks... so I bought this phone off of kijiji. the reason why my phone shows up as unrecognized sim is because apparently the phone is stolen.... after just getting off the phone with bell I found this out. so I'm out $450 bucks... I don't know if its possible but is there maybe anyway for me to revive this phone still? change the imei # maybe? idk...
You could unlock it i suppose and use on another carrier, you'd need to purchase a new sim or get one on a plan from a new carrier, unless it gets listed somehow. Not much experience with stolen handset. Maybe go back thru kijiji support and push for a refund.

I don't really wanna put anymore money into this phone if unlocking it doesn't work. and I tried to get a hold of the guy that sold the galaxy to me but no such luck. I think I just have a mini tablet on my hands? either that or a paper weight.
Sim card is like 50 bucks at most. Id unlock it (understand you'll lose LTE) and use a sim from another carrier. Can get them for travel or even online.

. I would unlock, and see if you can borrow a friends sim on a different carrier to make a few calls. If it works, try and get the new carrier to sell you a SIM. they may or may not, depends if the device comes back stolen for them too.
there are guides here you can use to unlock. Usually just a code and combination of presses to unlock. Don't need to pay for it. Search out a few guides. Isn't all that hard, and theres a few apps that do it too.

so just as you recommended I went on you tube and found a free way to unlock my phone. but even after unlocking it and using both a valid Koodo and Fido sims from my friends neither of them worked. both left with the same problem "unregistered sim / emergency calls only" So is there any real way to get my phone fixed? I dont think its possible to change the IMEI? not to imagine that its probably not legal... Any idea if I was to get a smashed s4 even if it was the i337M and say it was the US i337main motherboard would swapping it work?

[Q] Flashed stock rom, now no network?

Hi there, new to the forums posting but I read here constantly. I have an sm-900w8 note from Telus in Canada. I was running a custom rom before and decided I wanted to go back to stock before the Kitkat release. Anyway, I flashed the rom from sammobile.com that was for my phone (the link said it was for telus and the file even ends in TLS). So I flash it using odin and everything is perfect, the phone reboots and odin is finished. After that I decided I wanted to clear all my data and apps off the phone as well so I did a factory reset. The next time I turn the phone on everything is working (wifi gps ect) but I can't get on the network and it says I don't have a valid SIM. Also I notice the app packages from telus are not the correct ones and one of them is labelled Bell. So I am guessing the site has the bell firmware for telus as well? This doesn't matter to me but I do need my network running. Do you think it would just be a modem problem? Any information would be GREATLY appreciated guys!

The first and most important question: Do you have a backup of your EFS folder?
If so, you'll be happy. If not, prepare for the worst case scenario.

Seems you have installed a carrier FW on your device and it has SIM LOCKED it. try flashing another.
EDIT: @donalgodon - it's only really EFS when it boot loops and shows Android process not responding etc :good:

Well, that's not exactly accurate. The phone can boot with a corrupted EFS, but you will get no network access (and no IMEI number.)
It's happened to me, so I know it's possible. It's a common symptom of the OP's issues on Samsung devices.

Yeah I am sure I'm not in dire straights yet and lucily I have my backup phone to use for now. I am wondering though, sammobile is the most legit source for stock firmware around, do you guys have any suggestions? Or can I possibly even try just flashing a new modem through odin? (I have never done this but seems easy enough)

True, however, OP states that it was Telus FW that was downloaded and flashed...but it's showing BELL.settings, So the probability of it being EFS is low, it's sim locked the device via the BELL firmware more than likely. Reflashing the correct or unbranded firmware will indeed fix it

Well Sammobile isn't immune to mistakes, but it's rare it happens, they're genuine enough.. You could try the modem, first thing I'd do is test the back up and see if it's the downloaded ROM that has cause the issue.
And yes, you can flash the modem via Odin.

Check to see if you still have your imei or not... That's probably the reason, you lost your efs/imei...
If that's the case then if your made a efs backup like you should have,restore it. If not, try flashing stock.

Did you test your sim card and make sure it is ok? Try to out this sim card into another phone and make sure it works? Put another gud sim card into your Note 3 and check if the problem still persist?
Dial *#0011# and check for the RX, TX value? Can you post this screenshot here?

Here the screenshoot
Anybody please
No Network neither
Hi everyone,
i got almost the same problem. My SM-N9005 was on the Standard TouchWiz Rom (4.3, rooted) when i updated to 4.4.2 via Kies and rooted it again.
Now my Phone shows me signal bars but tells me "Emergency calls only". I still have my IMIE.
I reflashed the stock ROM but that did not fix my problem sadly.
Hope you can help me!
UPDATE:
I reflashed the stock recovery once again and factory reset/wiped the data and now it somehow works again. Maybe that helps
UPDATE 2:
It seems like that was just working for a short moment, now after flashing the X-Note ROM (and Kernel) the "not registered in Network" message comes again though i got like 4 bars. The bars just are random somehow and jump up and down every few seconds.
Another Update:
While charging the phone (via PC or via the original Charger) i get a Message that it stopped charging because the battery temperature is too low. I Hope nothing went physically wrong?
your note 3 seems to be unlocked by SPT box or BST dongle
select wcdma/gsm or 3g/2g in mobile network and your network will connect
hope this helps:fingers-crossed:
Thanks for the reply, but my I bought my note 3 unlocked and new from my carrier and havent changed anything regarding the IMIE.
I was thinking about the modem beeing broke down while i updated to kitkat, and therefore flashing a new one. Any ideas on that?

If everything else fails try to write in Odin (or better yet in Mobile Odin Pro) just the modem - and aim for an older version, something like MI6 (present in MI7 firmware) or MJ1. With Mobile Odin Pro you MUST be on stock recovery and it will work perfectly first time, with normal Odin there are some reports that you might need to write it twice or something like that - search around.

Tried that, had the same problems with the MI6, and with the MJ1 it got stock when i tried to unlock it...I was on the Xnote ROM though, Ill once again will try flashing the stock rom...
did you try another sim card ?
Sadly, the sim card works in my Note 2 without any problems... I think its sth that got physically destroyed somehow. When i plug it into the charger is says "stopped charging battery too cold"

Whats your model number? Go into the phone settings and check in there. The more details you provide the faster you will get an answer. Going through the Odin process you mentioned will not unlock your phone. It lets you change to different carrier firmware but you still need an unlocked device otherwise it will not work.

Strangely I cannot find anything on that model # you posted. Are you sure; there is F after GM950? Can you go to Samsung official website > http://www.samsung.com/us/mobile/phones/galaxy-s/s/_/n-10+11+hv1rp+zq1xa/ and find your model? Also, can you also share your baseband version as well?
Edit: Looks like you have the Exynos model which goes by different alias (SM-G950G, G950G, SM-G959FD, G950FD)? Is that correct? .
This happened to me earlier today also. I have the G955F since late May and all has been well. I wanted to Flash CarHDRom V.4.1.1 today coming from Renovate. First boot with new rom I get the unlock sim screen. (never seen this after almost 8 years of flashing) Also a standing message in notifications "network locked sim card".
The sim card works fine in my backup phone. Why would it all of a sudden do this and how do I find the unlock code? Phone is otherwise useless now.

Strangely I cannot find anything on that model # you posted. Are you sure; there is F after GM950? Can you go to Samsung official website > http://www.samsung.com/us/mobile/phones/galaxy-s/s/_/n-10+11+hv1rp+zq1xa/ and find your model? Also, can you also share your baseband version as well?
Edit: Looks like you have the Exynos model which goes by different alias (SM-G950G, G950G, SM-G959FD, G950FD)? Is that correct? .

S8 no service 1 month after rooting

Hi guys, this is a difficult one.
I have a buddy who really shouldnt be playing around with his phone. He has a samsung galaxy S8 on EE. He decided to root it because he wanted to recover some deleted files from it. Obviously its voided the warranty.
The trouble is a few weeks after he rooted it its now showing no service. Just to make matters difficult hes now played around trying to fix it. It is no longer rooted and it has the samsung official firmware on it. Theres no files on the internal storage to give clues to what he actually did and to make matters worse he has no idea what he actually did to root it. He seems very unclear on what he did or why he needed to root it.. Not a good start.
I have put a sim in it and it does ask what network the sim is on but says no service.
The trouble here is I am not sure where is best to start and I want to review my options before fiddling too much.
So far
I have flashed the stock firmware from Sam knows.
Also factory reset before and after.
Checked Knox status. Showing warranty void.
Currently not rooted and was not when I first got it
IMEI number is still present.
Tried multiple sim cards. 2 on EE and one on giffgaff
Phone storage is blank as if phone is new.
Phones owner mentioned twrp but bootloader is currently stock
Have you checked to see if the phone still has an imei number. He may have messed that up. If he has. Unless he's backed up his efs partition, ( think that's what it's called ) then he may have an expensive small tablet Instead of a phone...
Yes it still has an IMEI
download stock firmware from Sammobile and flash stock, then see, could also be problem with sim card...
I have tried flashing a sock ROM this morning. Also tried more than one sun card. Same result.
Maybe the phone has been locked by carrier ? some carriers do that if a customer is not paying subscribtion. Where did he get his s8 ?
Have you heard of that happening in the UK. As far as I was aware these days in the UK the phone is considered your property.
If it has been blocked like that could I get it unblocked?
Are you sure, the IMEI displayed is correct? Because it sounds like an IMEI brick, my old Galaxy S3 had the same issue.
It's IMEI became a generic one, that didn't match the original one on the box.
Ok I'll check with the owner. See if he still has the box. Is there anywhere else I could find the IMEI if he has thrown the box
You can try checking the bill of his S8. I bought my S8 on contract in a local retail store and got a bill, that included the IMEI.
EDIT: I just checked, the IMEI can also be found imprinted on the rear glass on the bottom.

You can check the status of an imei number online, there's a few websites that do it, it will tell you if it's been blacklisted or not.
I'm from the UK and I didn't pay my bill for 3 months once and they never blocked my phone, just deactivated my aim service until I eventually paid. So there's something dodgy going on tbh, how did this person purchase this phone?

I have just checked it on imeipro.info.
It is showing as clean and the IMEI number is correct.

I actually have no idea what else to suggest, if you've factory reset it, flashed firmware via odin and checked imei and all is okay then I'm unsure what else you can try. Usually issues with service is down to efs which leaves you win a corrupt imei but this is all okay for you. Can you ding out what software build was flashed? The build number.
subscription ended???

Sadly not. Browser history has been cleared and files have been deleted. He said it had been running fine for about a month so not sure from memory which one he used. He knows he used TWRP to root it but thats about it. Does not sound like he really understands the process, just used google and skipped through without reading.

Hmm I mean no offense to your friend there, but the root process is so simple not sure how he managed messed it up tbh, but it is what it is. If you're able to contact him get him to go to settings-about phone-software information. In this section it will show what firmware build he has, there has to be more to this.

Its not so much a matter of whats on it now. Its more a matter of what was on it when it died.
Currently
Baseband version G950FXXU1AQ17
Build Number NRD90M.G950FXXU1AQ17
Anything else on there that might be useful
The one I have on it now is the one I flashed via ODIN

That's the latest firmware available, the only last thing I could suggest is to use Samsung smart switch software and do a firmware recovery. If after that it doesn't work then I am all out if ideas.
