Sim Unkown ,Network Try later - Samsung Galaxy S7 Questions and Answers

I have a sm-g930f , the phone is from New Zealand , I am in South Africa , the phone was working 100% on the Spark firmware (Marshmallow)
I have since updraded to 7 and cant downgrade , the whole efs was lost , I recovered the IMEI with combination software.
I have checked the IMEI and SN nr all is clean , I chatted with Spark in New Zealand , given them the detail , they say phone is clean and not network locked .
I can see all the south african networks in Network operations , phone just say try later .
Phone shows correct IMEI and SN nr , but sim and phone number unknown .
Any advice please
Regards

Did do that , after some research , I think I need a z3x box , even with the original IMEI , the certificate needs to be patched

Ok , I got the phone to connect on SA network , with the home CSC . but stays connected for about 30 sec then goes to emergency call only
What is the IMEISV number under the IMEI , mine shows 01

Can someone please tell me what is in the CPEFS partition , mine is empty

What South African SIM do you want to use with your phone? Note that there is a CDMA network in South Africa Neotel, which won't work with your S7

[Q] MP 809T MTK 6592 No Network Signal & Flashing Issue

Hi,
I bought the phone MPai 809T Octa-Core MTK 6592 from China shipped to UAE (United Arab Emirates). I configured the region/country to United Arab Emirates and the phone was working fine in Abu Dhabi, UAE.
Now I am in India and the phone is not getting any signal from any Network Provider. The SIM card is working in other phones; but not in 809T. SIM Cards are detected by phone, it shows details of SIM Name, Netowrk Provider Name. But when I try to call, it says "Mobile Network not available".
I suspect the region/country setting is the issue. But I don't know how to change that. So I am trying to flash a new ROM; so that initial region setting wil appear again; which may resolve my issue.
I have got the links for 4.4.2 ROM from the link below (NeedROM website). But I am facing an issue during flashing. Someone pls help.

I am getting an error message while using the Flash Tool. Please help. Error message attached.
Thanks,
Joe
Upgrading to 4.4.2 didn't help.I'm still not getting option to change country and still no network. Someone please help. My mobile is just a gadget without sim functionality.
Please help.

S7 HELP! Phone changed imei, changed the model and cant connect to the network.

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!

Canadian s7 not recognizing getting network with a european sim card.

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 ?

XFA is the south africa CSC. where will you be using the phone? ive used the germany, uk, ireland, romanian and russian firmwares on my A8 here in the states and they all worked just fine. im betting that the phone is locked to its native CSC
i am using the phone in zimbabwe..
so if locked to its original carrier is there any way to fix it or i should take it back to xfa

the A8's are supposed to be unlocked tho. Did you buy it thru a carrier?
go to this address and search for xfa, youll see that its unbranded and should be able to be used on any GSM carrier. You might have to give the carrier the IMEI in order to get it working

Multi CSC FILES

Hello All.
I recently made the huge mistake of factory resetting my Samsung S10+ device and now it is locked to SK Telecom, Korea. I am just now realising my phone is a Korean make and all the available CSC files are korean.
1. Is it possible to flash a Custom/Multi CSC files onto my device and what is the process?
2. Right, my devices internet and cellular network doesn't work because it doesn't detect any sim card inserted. The Wifi works alright.
Please help
Download the firmware of your country CSC on Frija and flash it ?
Or it is blocked too ?
