If a efs from a s4 would work I'll hook you up. This happening to you has made me hold off on root for a while... also have a s5 efs backup
[Samsung Galaxy S7 Edge Questions and Answers] Equiptech:
Hard to say if the S4 or S5 would work without seeing data. Guess is probably not. Fortunate that my G935F was my rooting / ROM phone and Still have my G935A up and running. G935F is an expensive paper weight right now though. (Kinda half-ass works with a wireless connection. )

I've just had my old note 4 returned unrepaired from Samsung UK..

Had an issue with front camera as knox was tripped wouldn't touch it Grrrrrr

See email received and also pic they took and sent in email
[Samsung Galaxy S7 Edge Questions and Answers] Beefheart:
That's the first time I've heard of someone in the UK being refused warranty repair because of tripped Knox. By EU law they're not allowed to do that. They repaired my S4 around two years ago despite Knox being tripped. I think it depends on the repair center it goes to.
[Samsung Galaxy S7 Edge Questions and Answers] Braggster:
Went into Manchester Trafford centre got refused

Then set up a repair via post sent to norwich

Both knock backs as said

I had my s5 18 months ago repaired with tripped knox had no audio on main speaker..

Maybe clamping down now?
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
Sounds similar to what happened to me. The only difference was I did a full wipe (data, cache, and system) before installing Echoe v5 w/att csc. I don't know why it erased my efs, but it almost seems it's still partially there. My serial number is still in there but I noticed the csc region in the efs folder (inside imei) got changed to simply DBT when opened with a text editor which is Germany. She somehow efs got touched and should not have. I was looking at all the folders inside of efs using root Explorer trying to figure out if there was something obvious.

Was wondering if someone with root and working phone could look in their efs folder and see if it looks different im any way.
[Samsung Galaxy S7 Edge Questions and Answers] Equiptech:
I have root and have looked at my efs folder... It is empty.
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
You need to use ES file explorer and enable root and hidden files in the app then you can see it.

I wanted to add an update I tried flashing CSC from the NZ firmware manually, it didn't work.

Screenshot of my efs and meid error. (this is the original efs in my phone before i started messing with it. yes its backed up.

Now the strange thing is, if I DELETE the nv_data.bin and nv_data.bin.md5, it regenerates the 00000000000000 error and the phone thinks it has 2 sim cards by regenerating the files. So I think somehow i still have my meid in the files but somehow the phone cant read them. I tried fixing the permissions but I am unsure how.

I'd backup yours first though... even though it's stuffed
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
I tried flashing it and this happens. The folder in efs looks the same but when viewing the md5 it looks like the md5 hash changed. And I got 2 meid with 0's. It's the same behavior that happened when I simply deleted the folder and it regenerated. Now the weird thing is the screenshot with NO meid only occurs with my stuffed efs folder untouched. (and no signal) but I get signal but emergency calls and 0000s when I flash your efs or when I simply erase the folder and reboot.
[Samsung Galaxy S7 Edge Questions and Answers] MRDOCA:
Dang that sux. Guess there is more to it.
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
Yeah I think the file structure is different.
[Samsung Galaxy S7 Edge Questions and Answers] Beefheart:
They must be. I remember it was Norwich that repaired my S4 with a new system board despite a tripped Knox flag. It looks like phone insurance on these things is even more essential now.

Strictly speaking, they can't refuse repair due to a tripped Knox flag. But if they do what can someone do? Take them to court? You could buy ten new S7 Edge phones for the cost of simply starting the procedure off and Samsung know that.

Would anybody with a EFS backup that is not in the USA be willing to share with me?
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
I looked at the nv_data.bin in a hex editor, and discovered somehow GT-B3730 is in the text. this is Samsung GT-B3730 4G LTE modem. How the hell did this make its way into the nv_data.bin file? Its a European one as well.... So it WAS a bad rom? I am starting to think, something is wrong here. So no wonder WHY I cannot get signal unless I delete the .bin files.. its the WRONG model number.. And why the heck would a rom overwrite this upon install?

and to add to this, the recreated nv_data.bin file includes the G935F in the top of the code but the one below does not. What is happening here...

[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
Well I chose att csc. That would be what caused it I think.
[Samsung Galaxy S7 Edge Questions and Answers] Kjc99:
Ya At&t csc shouldnt work on a 935F right? You wiped entire system in TWRP? Or just factory reset.... Changing to a different csc should only make you have to factory reset..... It's says o the first page you made a backup but it won't work? What kind of backup? From twrp with efs checked or an app from playstore?

Also I flashed a PHN rom with Odin 2 days ago.... My old csc was TPA and I didn't even loose my data or have to reset? Weird issue.....

Maybe echoe rom forum was closed for a reason...... Maybe happened to more people besides you? Just tried to get into it but it says restricted

[Samsung Galaxy S7 Edge Questions and Answers] strikerdj2011:
maybe because its an international when you flashed the csc from an american network it could of messed with the radio bands i have flashed a few csc ones on my edge that been included with the rom like btu dbt have you totally wiped every single thing off you device and tried to flash rom again and selected you original csc file ?

EFS

Even though my phone is rooted, ES File Pro would not enable root explorer. I installed "Root Explorer" and now I can see the files in my efs folder. Many files and folders in there but I couldn't tell what would / could be wrong. Just gonna look around a see if something jumps out at me.

Solrazr... What Hex viewer are you using? Trying to look at my nv_data.bin and getting nowhere using "Hex Editor," "Hex Pirate" but get permissions error. Changed permissions and owner of .bin file but apparently not correctly, Frustrating. Do you have any SIM readings as I don't have emergency call options either.

I have done a complete wipe and TWRP restore of a backup that was working and rooted. Everything on phone works except call / carrier network functions. Connected to wireless AP I get partial functionality.

---------- Post added at 10:55 AM ---------- Previous post was at 10:36 AM ----------

In TWRP how much can I wipe and not mess with partitions. All of these? Advanced wipe / Dalvik, System, Data, Cache, Internal Storage. Factory Reset (swipe) & Format Data (button and have to type yes.) Then boot straight to "Download" and Odin Sammy Firmware including the csc file with the package. (Home-csc or csc?)
[Samsung Galaxy S7 Edge Questions and Answers] Kjc99:
Well hopefully Op gets a fix for this.... Scary situation.... But I have to ask you guys... What is the best way to save your EFS?.....

A full backup in TWRP including efs?

TWRP efs backup

Or an app?

Is it a matter of restoring it in custom recovery? Or does it require hooking to a computer/Odin?

Galaxy S7 edge
[Samsung Galaxy S7 Edge Questions and Answers] Equiptech:
When doing a TWRP backup, check all options including save efs also. Never know when you'll need it.

I was so excited about ROOT, TWRP and AT&T all working on an Int. S7 G935F that I over-looked some of the finer details of "Flashing Basics." My Bad! :(

Getting tired of people who are playing/flashing their phone with firmware they don't check 1st if it's compatible for their type s7edge...

Losing after flashing their IMEI and radio-reception...

And other people may come with a solution!

Think twice before doing anything to your phone without knowing what you are doing!
[Samsung Galaxy S7 Edge Questions and Answers] MRDOCA:
Someone posted this on the other forum. Worth a shot

"I found this after a Google search, any use? Restoring Lost/Corrupt IMEI: If you have already lost your phone’s IMEI, do this- Note down your phone’s IMEI. You can find it below the phone’s battery or on the box that it came in when you bought it. Create a backup of the corrupt IMEI file and open it with NotePad++ or any other text editor. Separate your IMEI number into blocks of two digits, leaving the first digit alone. Suppose your phone’s IMEI is 35516705558781901, separate it like this: 3 55 16 70 55 58 78 19 01 Now add “A” after the first digit, and reverse the sequence of the two numbers in each block of 2 digits. Add 08 in the beginning of the IMEI. Here is an example: 08 3A 55 61 07 55 85 87 91 10 Having done this, replace the first nine values in the NV block with the converted IMEI. Click on Write button on the NV-items_reader_writer tool. When it’s done, disconnect device and reboot it. You may have to search for the nv tool. Hope it helps in the right direction."

Yeah i flashed the stock new Zealand rom including csc. It didn't fix. I fully wiped everything. The strange thing is when I dirty flashed the Rom it didn't cause an issue, it was only when I clean flashed. (wiping system cache and data)
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
I just used file Explorer. You have to use root browser add on. I just viewed it as binary. Now to answer the other question, I had no emergency services only or signal until I deleted the NV. Data. Bin (after backing up the corrupt one) and rebooting. Android recreated a new one get signal and can see sim card etc... But no service as my meid is 000000000000. Originally before I did this I had no signal at all. I screenshotted the difference earlier in the thread if that helps.

[Samsung Galaxy S7 Edge Questions and Answers] melliwuk:
if you have erased your imei the ONLY way to correctly repair this is to send it to Samsung. I did the same thing on my original galaxy s it took me a week but I did manage to rebuild the efs partition but it had a default imei. Samsung are the ONLY people who can properly rebuild your efs partition...
[Samsung Galaxy S7 Edge Questions and Answers] Equiptech:
Was hoping, but that didn't work for me. Deleted the nv_data.bin and rebooted... same as before. :(
[Samsung Galaxy S7 Edge Questions and Answers] Equiptech:
IMEI

IMEI you talking about... is it in the efs folder. If so, this pic shows what is in mine. Looks bleak so hope that's not where your referring to. :(
[Samsung Galaxy S7 Edge Questions and Answers] ydenyse:
I don't know if this helps, but I fixed my G935F (different issue) with Kies. I had to enter in my IMEI and serial and then the phone fixed itself automatically. I did get a warning message though that Kies didn't support my phone but it did and everything worked.
[Samsung Galaxy S7 Edge Questions and Answers] MRDOCA:
No fix yet. But he got his baseband and a couple other things showing again that were blank. Equiptech is also in the forum so he will see if a fix shows up aswell. Fingers crossed
[Samsung Galaxy S7 Edge Questions and Answers] melliwuk:
Kies will NOT be able to repair the imei. The imei is stored in the efs partition, you can not edit those files yourself as there is no way of mounting it as rw that i know of. And even IF you sonehow manage to edit the files you will only get 0's or the default imei (cant remember the number). It will work, as long as its not all 0's until a network blacklists that default imei which they do regularly.

Any upload to the efs partition (even if it is a backup of your efs) will on next boot be detected as an unauthorised upload and default the imei. This is so people cant steal phones and change the imei.

The only way to repair it is on the machine sammy used to upload the imei at the factory (presumably in a special factory mode).

When i had to s3nd mine in for repair it took 2 hours on the phone with the samsung tech guys to make them believe what i had done as they just kept saying you can not alter the efs once it leaves the factory. That was the first time anyone there had heard of it as its supposed to be impossible as even in download mode the efs is read only!

So for your propper imei samsung IS your ONLY option... that being said, dont expect a free repair! I think the only reason mine was free was cause they they wanted to see if i was telling the truth!

When I got my Note II long time ago I have had the same problem, after flashing a custom ROM, I lost my IMEI,no cellular coverage, just one guy was able to help me restore it, I can PM you his phone number you can add him to WhatsApp and see if he can be any online help.
[Samsung Galaxy S7 Edge Questions and Answers] middleearth1010:
Yes i appreciate it a lot. I'll try to talk to him. In the meantime I am gonna try to pawn this phone (I got the original receipt) see if I can het a couple hundred for it and get an Xperia compact or another S7. If anyone wants to buy it for parts along with receipt let me know. At this point I think this phone cannot be fixed by me, and I appreciate all the help and support. I made the mistake of going off xda to play with roms from shady developers who refuse to use xda and close their forums. I learned an expensive lesson. Even backing up efs isn't guaranteed.

If anyone can still fix it, ill pay for it, otherwise I'm exploring my options to sell this junk. If there is a fix before I actually sell it awesome, if not keep this thread open for so hopefully there will be a fix for someone else.
[Samsung Galaxy S7 Edge Questions and Answers] pro_b:
I'll only chime in once. I have access to the other mentioned forum and I've used that other rom since the beginning. I have the G935F international version and my carrier is ATT. I have not had a single issue related to my IMEI and I've flashed each version of the rom. While I've been closely following here and there hoping for a solution, I do not believe it's fair to automatically assume that it's the rom in itself that caused the issue when there are so many other people using it as well. It could have been a combination of user error when trying to flash the rom that likely caused the issue. I'm not finger pointing, but I'm trying to prevent other needless finger pointing. From what I gather, the issue is likely related to flashing an incorrect CSC. There is an option that clearly say (choose this one) if your region's csc isn't listed. I've done that every single time (because obviously ATT isn't listed) and I've not had a single hiccup with my signal, baseband, modem, efs, etc. Please don't take this as an insult to anyone but more as an attempt at clarification. On a Side note, I believe I'm aware of 3 people in total with this issue and 1 or 2 of them have openly acknowledged user error and the dev over there has been going out of his way to assist with helping those users resolve it, up to the point of offering to help pay for costs of repair (even when there has been verification that it was user error). Again, I hope everyone find a working solution and I'll pass along any useful information I come across as well. Best of luck to everyone and please carry on.

That would be helpful a lot. If I can fix it, I am going to sell the phone. I bought a Moto X Pure Edition and it holds signal way better then the Galaxy S7 Edge in the house on tmobile. I found a backup of my original corrupted efi on my pc on one of the programs i was trying to tinker with. I am wondering now since it is under warranty, if I could reset the tripped know somehow. I wonder if it might be better to simply hack that then swap for warranty.
