So I've bought a second hand galaxy s7. It is a Canadian model SM-G930W8 . I live in Greece and have to use a greek sim card , the phone recognizes the sim card , but in the info it says unknown. Prior to an update I made it worked fine , but after the software update I am unable to get network reception . Anybody happens to know a way to fix the problem ? Will flashing a greek firmware solve the issue ?
You can try flashing just the home_csc, which contains carrier and frequency settings, from the Greek firmware onto your G930W8, but I'm not sure how different the 930W8 is to the 930F so you might risk a bootloop and have to flash stock. So make sure you've got what you want backed up.
What was the source of the update? Phone shows the correct IMEI?
I believe the 930w8 is exclusive to Canada.

Somehow the update messed it up? Is it a stock update from Canada? I have a Canadian s7 from bell on 7.0
I updated the phone from samsung smart switch , the phone was probably modded beforehand to run greek sim cards, and the seller never mentioned this.And with the update the mod was most likely wiped or something.

Try a different stock from sammobile or a Greek rom. But there shouldn't be that issue. Mine works in London with no problems.
I asked about the imei to ensure that the phone is showing the correct imei.
The model number has been confirmed in download mode?
Yeah I went in download mode and it is the one I have stated above , same model number on the back of the phone , I will check the imei when I get a hold of the phone , because a friend has it right now. Will try to flash greek firmware. And report back.
I booted into recovery and what is said there
-- applying multi-csc...
Applied the csc-code : TLS
successfuly applied multi-csc
That means that the phone is using the Canadian Telus Home.csc (I guess) .
So would flashing the home.csc from the Greek firmware work ? Does it have a chance to hard brick the phone ?

Hi,
This is my first post but, I'm an avid lurker. I am having some issues with my girlfriends 920i. It received an OTA update to marshmallow and ever since it won't read the Sim card. I've tried to flash the official fw through Odin and still having the same problem. Because it doesn't read my Sim card, I have zero access to any mobile network settings.
I am wondering if when they updated the marshmallow, I lost unlock capability.
Also, her imei and sn still match. Most of the problems I see people have are mismatched numbers, and her phone seems fine.
Any help would be greatly appreciated.
So, I checked the firmware that I flashed and it was INS which seems to be the locked version.
I flashed the INU firmware this morning but still not reading my SIM.
I'm out of options at this point, I'm going to go back to lollipop and see how that goes.
Hi,
I am having this issue for my SM G-920I since 2/3 Jan, 2017. I am using fine on US Tmobile network since Oct 2015, but all of a sudden got the no SIM, emergency calls only and continues to stay like this.. I am curious to know if you resolved the issue and how. Thanks for any feedback!
Help me please
I'm having the same issue. Just flashed INS 6.0.1 firmware on my brand new G920I and now i can't get any mobile signal or data. Tried to flash ZTO firmware for my country, but same issue. My phone was fine before flashing INS firmware. IMEI it's fine too. Recovery shows: Applied multi-csc. What can i do? ((((((((((

Already updated and tried to downgrade to 5.1.1, but no sucess. I don't think it's a hw problem, cause it was working before the INS firmware flash, and IMEI number still shows right, no matter what rom i flash (now on MIUI). Can i clean EFS partition and try to flash ZTO firmware again, or i might lost my IMEI and get more problems? Also, wondering if advanced wipe with everything checked on TWRP can help. (data, internal storage, system, sbfs, cache, dalvik cache)
Can you open the phone dialer and enter this code *#*#4636#*#* then clikc Phone Information, and send a screenshot of what you see in the screen (Make sure no IMEI in the screenshot, before you post it here) ? Also check if Radio is OFF or ON.

Codes on my dialer doesn't work, but i'm sure the IMEI is right cause it's showing in phone information. Also, radio is on cause when i search for mobile networks the carriers of my country appears on the screen but when i click on then, just appears a message saying that can't connect
Same problem, any solutions?
I had same issue for over a year, you can check details in my thread, resolved by factory warranty motherboard replacement (free of charge, even thou knox was tripped when I bought it, and I told lady in authorised repair shop that i don`t have warranty).
Forgot to mention that I also tried to repair it via Octoplus box, both by me and some other people (wanted a second opinion), DRK fixed, few new certs written, etc.), not only by flashing fw via Odin or Smart Switch.
And I was 99% sure it was hw, turns I was right.
P.S. country dependable: - in some countries they will probably want to sell you a new motherboard in Samsung (happened to me), but in other factory warranty will be accepted (probably, if the phone is not older than 3 yrs I guess)
Hi Guys
First of all, i´m sorry my english is not very good and i have to use a Translator.
I recently bought a used SM-G930F. The previous owner had flashed before so although everywhere says SM-G930F in settings in "model information" says "SM-G930FD". Also when a SIM is inserted the "DualSIM Administrator" appears. Had Mashmallow installed and worked perfectly.
I wanted to try flashing the new NOUGAT BTU firmware stock. I did it through ODIN. The process had no errors. When the phone restarted I see that it has no signal. It recognizes that you have a SIM card inserted but "emergency calls only" appears.
The IMEI was not deleted.
Immediately I downloaded a stock firmware from my country ARGENTINA to go back to MARSHMALLOW and I installed it but the same thing is still happening. Then I tried to download another stock firmware from my country and my operator CLARO ARGENTINA, but the same thing is still happening.
I read in forums that the problem may be the modem, but I understand that is modified in the box "CP" of ODIN when flashing.
I honestly do not know what else to do. I also do not remember what firmware I had before doing the whole process.
I understand I should have backed up everything but I did not.
So I ask you please if you can help me.
Thank you very much

try flashing the specific modem and bootloader of your phone. you might want to try mashmallow modem.
You say I try flash only the modem and bootloader that come included in stock firmware from other countries? Must I only check the boxes "BL" and "CP" from ODIN? Thats correct?

I also tested Firmware flash from several countries in America and others, for example Chile, Colombia, Brazil, Mexico, Germany, Portugal. I also tested with some G930FD firmware from Vietman, Singapore, but there was no case. The only thing that stands out is that with Vietnam although no signal, "allowed" the band 4G, did not allow it in all previous cases, do not know if something to see.
u have any issues with wi-fi?? it looks like a modem problwm to me..
Try flashing the stock rom back with the samsung kies program so it will flash back the original stock rom that came with the phone and see if you then have your connection back. If that works then try to flash the BTU.

Good morning XDA,
I'm in desperate needing help, sorry but English is not my first language.
My brother bought a S7 G930F - Exynos that was GSM locked with one company here in Brazil, so he paid a guy to unlock it.
After getting the phone back I notice that the phone now shows G930FD, when I use *#06# to see the IMEI, shows two number, as if it was Dual SIM and both numbers are different that what is written in the back of the phone and the box and the rom seem to be 6.01 but with a lot of programs pre-installed.
So I downloaded the newest ZTO stock rom from SamMobile and flashed, now the phone is on 7.0 but can't connect to the network and still show the tow differents imei numbers.
Any tips or guidance and how can I Solve this?
Thanks, TggB!

Just insert Indian sim and reset your phone. Hope you know how to reset your phone.
Flash indian firmware, inserting indian SIM and "resetting" your phone won't do you ****.
If you have a SM-G955FD, you can flash G955F firmware on it just fine.
Im also having uae s8 plus. Just insert any of the Indian sim and switch on. After few minutes you will be notified to restart the phone and factory reset. Do that and volte will work.
Hi respected members, I'm new here and I need your valuable assistance .
I bought S8+ and when I checked the model version in software it is showing SM-G9550 which is Chinese version not Hong Kong, but on the back of phone G955U is mentioned. For more confirmation I compared the IMEI and serial number which are mentioned on the back of phone and also showing in software information in about phone. IMEI and SN are same in about phone and on back side of phone. I also checked the carrier in downloading mode (after pressing Volume down + Bixby + Power Buttons) and carrier is VZW which is Verizon if I'm not wrong.
I'm foreigner in China and current Chinese version is creating problem in phone that no any update (current is 7.0) for my S8+ software and the latest security patch is 2017, some APPs like Facebook and Whatsapp don't show any notification etc.
I already used Hong Kong firmware in my GalaxyS7 Edge which works perfect and also have Google APPs, but Chinese version don't have Google APPs, and there is no any play store library. To solve this problem, I tried to install Hong Kong based firmware (9.0) but Odin shows error that can't create partition, after reading about this problem it seems that firmware is not compatible with current hardware.
So I want to ask these questions!
1: How I can install Hong Kong firmware in current situation or if I install G955U then will it work in China? and from where I can get unlocked firmware because I'm unable to find unlocked firmware. Reference (https://firmwarex.net/samsung-s8-sm-g955u-9-0-official-firmware/), from this link which will work in my phone?
2: If I used PIT file to install Hong Kong version then is there any security problem or my phone will work well?
3: I'm unable to find PIT file for my current problem. I also need PIT file if first option will not work.
Sorry for too long explanation.
Need your kind suggestions. Thanking you in anticipation.
My problem is seems to be same as https://forum.xda-developers.com/galaxy-s8+/help/g955u-using-g9550-firmware-t3766862
Problem solved
I have solved my problem. As mentioned in my question G955U model is using G9550 because processor is same but RAM and storage is different.
I downloaded G955U1 from SamFirm and installed it. Working fine now.
I used this phone in China and Pakistan. The main problem in G9550 I was facing, it was 4G signals strength that were very weak in China and 3G was not working but in Pakistan 3G was working fine but no 4G signal on same phone. May be that was due to different bands. But now after installing G955U1 the LTE signal strength is very strong even better than iPhone X.
Still I'm searching about it that how anyone installed G9550 in G955U as I also tried latest G9550 on same phone but I was failed.

These guys will cross match the csc files to include carrier features for other country's. You can't out right install the 9550 firmware but can add bits of the csc to it. I've seen a bunch of "mutt" frankensteined devices. But don't like to get involved because stuff can go wrong real quick

Agree with you. I want to add bit more that G955U is 4GB RAM and 64GB Storage but G9550 is 6GB and 128GB. Obliviously firmware check the right configuration. As per my knowledge that we need to provide right BL (Boot loader) file. I mean BL file from G955U but other files from G9550. May be I'm wrong because I didn't try for it. This combination will work?

i have a similar problem too. i have a sm-g995u, i know because it is written on the back of the phone and also in the software info menu. however when i get into the AP and CSC values it says my phone is sm-9550. im currently suffering from poor network and i've currently lost signal. i mean my phone has been displaying "no service" for the past 2 days. I'm currently considering flashing another firmware but scared not to brick my device since i am a newbie with all this stuff.
my device is originally a g995u, if i flash a g995u1 firmware would it work?
what g995u1 firmware did you flash? i need help asap, ive been offline for a while because of "no signal" problem.

Yes you can install G995U1 in your phone. In my case I was also facing poor network issue, no phone call history and no live location for maps but after installing the G955U1, everything is working fine.

However, my problem still remains, i still have no access to network. i cant seem to toggle or change network mode. its stuck on LTE/3G/2G, i suspect when i was on the road the connection to the lte was lost and failed to switch to the 3G. i see alot of people have similar issues.
i sincerely hope it is not a hardware issue like a roasted network chip...

It seems that there is problem with your network chip but yeah you should make sure that your phone hardware is based on G955U. G955U (USA version) and G9550 (Chinese or HongKong version) have same processor. As I already told you that my phone hardware was G955U (Verizon version) but G9550 firmware was installed because I bought it from China. I was facing many problems like slow speed, no live tracking of location using any navigation app, no call history and poor network coverage. After checking the phone I came to know that originally phone is G955U, you should also double check your phone version especially in downloading mode. After all I installed G955U1 (unlocked version) then everything works well. If your problem is same then G955U1 should work well. I installed Android 9 version.
Furthermore if you will try to install other versions like F (Global version) then obviously you will face other problems too.
