No service and 4G! Really no fix :? Please help :( - Samsung Galaxy S7 Edge Questions and Answers

Hii... Have been searching forum but seems like no one has the answear
Galaxy s7 edge european version. Phone worked perfectly for 4 month and then suddenly I lost mobile network and service Tried hard reset, network setting reset ect. nothing helps Put simcard in different phone - everything is ok.

Check that you're baseband isn't "unknow". And check if you lost the imei

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.
Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

I rooted it wrongly and someone interfere and make stupid things using root explorer . i did not install custom recovery .
after figuring out the problem . i installed stock rom and then i rooted it probably then installed cwm custom recovery . after that , someone told me that i should install and try some modems which exists in sweet rom for N910C , i tried many of them but even that nothing happens still the fake imei and fake serial .

help?????......
same problem now as mine my IMEI just became 350050500009692 /01 emergency call only why???
some nice paper weights at least lol none of you have efs back up ? tried restoring it if you do common rule with samsungs all ways back up you efs folder
the sad thing there is mine I don't have my backup
Try NV restore (If you have it Pre-backed up on your phone from factory- at least mine did not have on the N910C but it existed on my N910F) ... Dial: *#0011# , then Menu>Back, then Menu>Key Input> then type Q0000.
After that I don't know where the NV backup is (I forgot, and I don't have the phone now), but you should be able to search here on xda or google it up...
I hope your Exynos has a NV backup....
Good luck

Absolutely rooted
Have you tried to restore using it?
I don't really trust these apps (bad experience on Galaxy S4) I would rather use Terminal emulator and type proper codes, which I want to know
Sorry if this is irrelevant but why do you back up imei?

Backuping EFS partition will backup data like device specific essential information such as the IMEI (International Mobile Station Equipment Identity), wireless device MAC address, baseband version, product code, system ID and NV data.
If you lose your IMEI during flashing and wiping roms, you will end up with a piece of brick incapable of making calls:crying:

I flash renovate rom and serial number on the back of the phone is remove. I know what is my imei but i dont know how to put it in the phone. I think my imei and serial number is removed in efs folder because renovate rom use uk firmware and my phone needs nordic firmware but even if i flash nordic firmware with odin it's not solve the problem. I call samsung repair store and ask how much pay if they fix my phone and they say it's pay about 400-500€ so i try to find another solution fix that problem

So you assumed that the fixing the IMEI would get you your SIM network? Did you get the famous "baseband: Unknown" problem?
Because that's something entirely different... or so I've been told.
What baseband/modem what CSC??

What ROM are you running? Are you on stock? What is your baseband?
All of these questions can be answered by taking a look at "About Device" in Settings

Do you have baseband and CSC correct for your network.
Suggest returning to service center if you don't know .

I had the same problem. Tried all kind of difficult how-tos, but the one which did the trick is just try to flash another Kitkat firmware (one meant for a different country). I bought my Note 3 in Belgium, so I assumed it needed a Belgian firmware. That was not the case. A French firmware did the job!

If it says Sim is not Verizon then it's most probably locked
Dial *#0011# and check stats
Also check service menu code or Samsung phone info app from playstore to check lock status of your phone
If locked
Try using tool/apps like Samsung Firmware Tool,Z3x to unlock or check forum for unlock method

I don't think it has anything to do with a custom ROM it has more to do with EFS and CERT
I'm sure there are several ways of unlocking your device
1)you can turn to legit paid services
2)you can look up for applications that allow for unlocking Z3x,Octopus/Octoplus, Samsung Firmware Tool etc
3)you can look up for local hardware/software repair shops that offer unlocking for phone's (usually coz they have expensive box)
When you have finally run out of options
4)if in your country its legal/allowed to change your device IMEI then get a working cert/efs for N910V

The problem can be your device being locked, your only hope is local marketplace or using a tool yourself but most of these applications ship with box and that is very costly there are cracked versions too with loader but obviously I am not at liberty to provide them on xda ,the other issue is most of these applications with loader wont have support for N910V because I check the one I have and thats the latest one I could grab ill check Samsung Professional Tool for you as well if it has N910V in device list
