The last zero 0 was until now FOR Demo phones. If samsung has not change the rule with note edge i think you bought an Demo phone.... For that to work you need to replace the mainboard and to buy antenna cable)
Hope I'm wrong....

Thanks, I did it but I still have the same problem nothing happened

As you wrote - signal lost after update "nv item" - do you remember what you change? back to previous version should help
did you make back up of changed datas?
did you try factory reset?
try other simcard - maybe simcard died?

Reflash stock 5.1.1 ROM via odin to solve your problem.

Did you make sure it wasn't stolen?

Please help .... I have a similar problem.
The SIM card it is inserted in the phone, but the phone still writes: Please insert SIM card
The SIM card is new and in the other device is functional.

Please help .... I have a similar problem. Writes that: No SIM card plugged in.

Please help

try checking csc via phone info.

Any fix to this?? I've just gotten the same problem on mine! Thought it might have reverted back to the region lock as I am now using a USA sim card and started off with a UK sim card. Just ordered a new UK Sim to see if inserting that one will fix the issue

Please .... Solution
Same problem here... No sim card.

I had this issue with my first Galaxy S6... I went into the three shop and checked my sim and that worked with another phone, but my phone would not accept any other SIM card. I was told to send to Samsung for repair, luckily I was in my 30 day amazon exchange period so I just sent back to supplier and bought a new one.

Same poblem here.. When i insert sim card, the phone restart and when enter in Android show message... "Error occurred while unlocking network... Network unlock code block".... Its a Japan Docomo network.. U think that can resolve it with a subsidy code? To unlock a sim?

Solution needed urgent
Hello everyone till now their is no solution anyone can help plz reply,
i tried to unlock by z3x box pro, octopus box and spt box with no solution, even try to change CSC, rooting, reflashing the same problem still!!! . any solution?????

..same problem here, did anyone managed to fix this?

Also got this problem. Woke up randomly and now it just says no sim card no matter what i try to do.

does any of you have also missing mobile networks menu?

Yes missing my network menu same issue

Any solution for this problem ...
Check my sim jacket by checking hardware
Reinstall many fw with odin even with twrp
Imei is OK efs OK im from Pakistan

This is what did the problem this sim problem appears days after doing this
1 flashing other rom model on different model like XEF on BTU...
2 updating android OTA failed
3 flashing with smart switch
Its not stolen its the g920f is the problem its sucks dude
If you dont have backup for efs folder and radio folder you need to fix it with octoplus box if you have warranty take it to samsung or if not visite repair place and ask for octoplus compatible with s6 but
This is what you get
1 Working sim
2 signal drops time to time mybe disconnected during calls am sure you get disconnected because i have
3 flashing stock you get stuck in bootloops
And if some one ask you about s6 the answer is dont say s6 its s sucks
Enjoy samsung junk smartphones

you mean the stock firmware cant repair my Efs and we need to fix it by octoplus box ? but here is not the problem of efs. my phone showing exect imei and s/n everytime...

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 ?

I need help verifing if my phone is original and I need to find the firmware

first of all sorry for my bad English.
so I bought this samsung galaxy s7 : "SM-G930FZAAFG"
box said it was made in Vietnam but when I check my IMEI in the net it said this :
G930F Galaxy S7 (SM-G930K)
SIM card size: Nano Sim
and when tried to find the right firmware I found this :
KTC - South Korea - KT South Korea - G930KKKU2ERJ1_G930KKTC2ERJ1_KTC
I installed it and all but only one sim is detected as if the other one dose not exist at all .
but when I bough the phone both sim's were working and the phone has two slots
I am trying to find the right firmware for this phone
plz help me I tried everything
btw can I share my IMEI number ?

What is the model # shown in download mode?
IMEI in the phone matches the IMEI on the box?

The model # shown in download mode is the model # for the motherboard in the phone.
Looks like the sm-930k does not support dual sim: https://www.phonemore.com/samsung-galaxy-s7-sm-g930k/specs/3319
Why did you flash different firmware?

still the same

Both sim slots could be used at the same time?
Sounds like the phone may have been put together using different parts.
The 930F and 930k are not the same phone.

Unfortunately, Odin will not let you cross-flash bootloaders or ROMs. Cross-flashing may even brick the phone.
I recommend returning the phone as soon as possible.

thanks mate your reply's where very helpful
I will do that .. it's my only option

I searched and it seems to me that they were installing a custom rom !
becouse I did install a custom rom and it worked fine before flashing the phone with the SM-G930K

so I will install this one :
https://forum.xda-developers.com/galaxy-s7/development/rom-superstoc-rom-v1-0-aroma-t3496520

Good luck. Please report back with your results.
Thanks.

- Update -
I just installed TWRP for SM-G930F :
twrp-3.2.3-0-herolte
and then I add the the custom rom :
SuperMan-Rom SM-G930F V3.0.1_O_Final
and now everything is working fine even the sound and duel sim is working too

if we recap on this phone on the back of the phone it said SM-G930FD
and in Samsung download mode is said : SM-G930K
and on the operation system I am using a custom rom that said SM-G930K

by the way I am stuck with the TWRP can I flash back only the stock bootloader ?

You can but changing only the bootloader may cause problems with the installed ROM.
You should only install bootloaders that are meant for the phone model number that is shown on the download screen. Never try to downgrade the bootloader to an earlier version because this may cause additional problems that include bricking the phone.
