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.

[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?

SIM Unlock, blocked???

has anyone tried to sim unlock their phone AFTER the update to 4.3???
I'm asking because I have a BELL i337m, upgraded to 4.3 and decided to unlock my phone after.
I tried 3 different sites to unlock my phone, they all gave me the same code and nothing happens
I tried downgrading to 4.2.2 but this wasn't very successful, its stuck in the boot animation screen
any ideas?

I know it's not helping, but I received my Bell phone yesterday and it was shipped with baseband I337MVLUAMG1. I tried the "free sim unlock method" found on this forum, but it doesn't work. I cannot access service mode (*#0011#, Menu button, Back, Menu button, KEY INPUT, 1, OK).
Still searching for a stock rom that will have the service mode enabled...
Dont waste your time looking for a free unlocking service..Pay 29.99 USD and have it umlocked from cellunlocker..you will be happier in the long run as i am..thank me for not wasting time unlocking for free..

I am having pretty much the same problems on my Telus/Koodo i337m. I recently updated to the most recent firmware (4.3) on the advise of cellunlocker because the code I was given was not working. None of the codes work and I can't even access the screens to do it manually. I have recently rooted it, props to Chainfire, but have no luck with most of the service screens. I'm still working with Cellunlocker to resolve the issue. I had access to all the service screens/menus on MDJ but not MG1 or MK6. Wondering if maybe the update missed some files or if the update locked some features. not sure if this is helpful but I'm happy to share whatever information I have to help others with the same problems.
Same here,
Bell with MK6. 3 sites provided same unlock codes. Nothing works, service menus different, etc.
Can't downgrade to 4.2.2 since image found crashed (bricks the phone). Image I found was at Sam Mobile
Apparently BELL will unlock it for 50$ but require original sales receipt, which I don't have (purchased phone on ebay)
Just paid BELL $57 to unlock, and their code is the same as all the sites... NOT WORKING !!!
I wanted them to give me the 1st 2 digits and last 2 digits so I can refuse before payment. But they insisted on pay first - code after - code by email. Luckly I had an employee of Bell at Bell Boutique confirm code not working.
I'm now on hold (1hr) to try see if they have another code?

I think you're right... I ended up buying a code from unlocksamsungonline.com for 29.71$ CAD with a coupon. Received the codes in 55 minutes. Hope it works...
My provider Bell Canada, gave me the same codes as all these sites, and they don't work on 4.3. Looks like Samsung has a major BUG in 4.3 in regards to unlock. Bell says call Samsung ! Go figure!
Problem is that will take a while to fix, aka get it out to consumers....
Chatted with Samsung, they say call BELL !
WoW !!!

Are you sure your phone is locked to bell?
Did you try putting different simcard other then Bell? Did your phone ask for unlock code when you put the other carrier's sim?

this still doesn't work.
Paid and tried from 3 different sites, they all gave me the same exact code
I think that the update has locked the bootloader and anything else.
I was reading somewhere that Samsung may be blocking the sim unlock and forcing people to pay roaming fees
Well all I can say is that this has been a huge step backwards for Samsung (from my point of view) locking/blocking features, really is a major turn off for me.
I think its time to look at other options until someone from XDA figures this one out.

100% locked to Bell
I have the original sim from Bell and is working fine
Put a Fido sim and asks for the unlock code, when I enter it, it says unsuccessful
everything is correct, IMEI has been verified many times and the codes also
Samsung is blocking something here with the latest 4.3 MK6 update

BTW, I just got off the phone with Samsung, they say that I have to take this issue up with my service provider.
they are not able to help me and answer why my unlock code isn't working.
he did admit however, that there have been multiple calls about the 4.3 upgrade and that Samsung is going to release an update very shortly
let's just hope that this will rectify the issues that we have been having

I restored my stock rom (Bell I337MVLUAMG1) and was able to unlock successfully my phone. I used a Telus SIM and was able to receive a phone call. BTW, I never updated my phone to the stock 4.3 update.
So it seems that you must be stock for unlock codes to work. For the record, I was using KANGAKAT KOT49H 6.0 when the code was not working...

I unlocked mine on 4.2.2 AMG1 flawlessly.I never updated to 4.3 and looking at the threads regarding KNOX and locked boot loader, probably I never will.
I am wondering if you can flash the MG1 radio from 4.2.2 and try unlocking the phone.If successful install the radio from 4.3 again.
I am not sure weather we are able to flash old radio on 4.3 though.

[Q] Galaxy S4 (SGH-I337M) says NO MOBILE NETWORK (HELP!)

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"

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.

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

Problem with G930AZ Unlock

I havent been able to unlock my phone phone i bought it off ebay and i cant seem to unlock it. i bought the unlock code from two different unlock servers and they both appeared with the same code but it doesnt work i was wondering if anyone has had this same problem and was able to fix it. i would apreciate the help thanks in advance.
You have to wait a while for the unlock to go through. I've never unlocked my phone but I've seen videos so I have some knowledge

Something happened with OS in your phone. Maybe it was rooted, or maybe some error in the system. Any how. Just flash your phone with stock rom. The original firmware that it had, and the code should work. Also try factory reset first. That may work as well.
Good luck.

I have tried every 930u a and v combofile and qc engboot file I could find... I've done the FRO unlock on many before this but this one is nuts... i think she may have done something else I dunno/..

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.
