Changed csc, lost signal, need help - Samsung Galaxy S7 Edge Questions and Answers

Hello, yesterday i bought used samsung galaxy s7 edge dual, sm-g935fd. It was rooted, owner said root was done to flash a rom to let phone see two sims. Went back home, started to install apps, and saw that snapchat doesnt work with rooted phone, so turned superSU, chose full unroot, phone did restart but stuck on bootloop. All I saw, was csc:g935f0xx1bph1 and pda:G935FXXU1BPLB. Could't find matching pda and csc roms, so installed another, for g935f, and everything worked fine, except from network, it only says emergency calls only and no signal, but it finds that my sim is from tele2.
On other thread i saw that i can use home_csc for my csc code, and any other pda, bl, ap, tried that and odin failed to flash it, so now flashed netherlands stock rom that changed my AP:G935FXXU1DQEF CP:G935FXXU1DQD7 CSC:G935FPHN1DQD1 Model: SM-G935F/DS.
Can you guys help me to get my network signal working again? I think that matching software for my phone would fix it, but i cant find which one to flash, or is there anything else that could have caused that?
Thank you for your help.

Sounds like your EFS is corrupted...
*Encrypted File System (EFS) | The EFS refers to a folder called EFS which can store information like meid, imei, serial number, config, diag settings and radio settings, etc in an encrypted format at the file system level stores. So it is very neccessary for us to backup EFS before flashing ROMs.*

i dont think that they can help me. I am not really good in flashing, because english is not my native language so i dont know what kernel means, whats the difference between firmware and software, and even rom, but i think that i have wrong bl/ap/csc/pda or something like that. Found that F in sm g935fd means it is international, looks like i can flash any country unbranded stock rom, but somehow it wont work for me, and i cant believe i did that much damage just by clicking on unroot in superSU app..

If I'm not mistaken, the contents of that partition are unique to your phone. Restoring from someone else's won't work or help you.
Try using Odin to flash the BOK3 Factory Restore image. It will delete everything and reset your phone; provided you have a valid SIM card, the phone should then regenerate your IMEI
Yeah it should work, but no, it doesn't, and I heard that the information can be changed to build your own one.
Or can you tell me how to restore it in AP, CSC, BT? i alreade flashed it on AP but it doesn work.

Are you sure you have a verizon S5?
You flashed this G900VVRU2BOK3_G900VVZW2BOK3_G900VVRU2BOK3_HOME.tar.md5 in odin in the AP section and it failed?
---------- Post added at 10:08 PM ---------- Previous post was at 10:00 PM ----------
here is the 16gb S5 pit file Load it in the PIT section then load the BOK3 tar image in the AP section make sure under options that repartion is checked. If it fails pull battery try again plug cable into different port on computer maybe try different cable. If it still fails you dont have a verizon s5

I already do that and install the pit and the firmware and then i realize that Odin its saying that is a Firmware update and no a restoration and when the s5 starter back like if it was an actualization.

If you cant flash the above firmware then you can't flash anything verizon. Are you sure you dont have one of the Verizon partner phones as they take different firmware. What build does it say you have on the phone?

If you don't have a SIM card in, you're not going to have any useful IMEI data. The SIM is what allows the phone to communicate with Verizon's network. What were you planning to do with a phone without activating it?

Recovering IMEI And Data Connection After Flashing WRONG Root Package Intended For I9300:
Make sure you have Samsung Kies or the Samsung USB Driver installed on your PC.
Download and Extract: Odin3 3.04.zip - 457.11 KB to your PC if you don't already have it.
Download and Extract: Param_Bin_I9305.zip - 612.14 KB to your PC.
With your Phone Switched Off, press and hold: 'VOL DN' + 'HOME' + 'POWER' to enter Download Mode.
Connect your phone to your PC via USB Cable and start Odin.
Check your phone is connected by seeing if a COM Port in a Blue box is present under ID:COM.
Press the 'PDA' Button and select the 'Param_Bin_I9305.tar.md5' file you extracted from the Zip Archive earlier.
Press the 'Start' Button and wait for it to finish flashing. If successful, you will see a Green Box with 'PASS!'.
Wait for your phone to reboot then go to your Dialer and press: *#06#. You should now see your IMEI and your Data Connection will be back.
but this is for an s3, and is talking about param_bin that should be tha NON-HLOS.bin, or i am wrong?

OK, firstly thanks for all your help.
-The Pit file that you give me I already flash it and it didnt work.
-I tried to flash the official firmware, and it didn't work.
-And already flash both of them together.
-I already tried with a Verizon SIM, and it didn't work.
-Already flash the modem and it didn't work.
And with the text that I put on the previous message, is from a guy that solve this but flashing a param_bin.
But in the s5 we dont have param.bin, but we have a NON-HLOS.bin.
So, I already have the same problem. I doesn't have the .nv_data.
And I'm currently Root in the BOK3 version. And I don't know what to do.
How did i know if i have a developers edition? that would change something?
Here is a backup of efs partition made by flashfire

Hi i'm new to the forum,

I have already formatted everything (data, system, factory reset etc...) in twrp and flashed the right rom for my phone with odin but the dual sim feature is still there and i don't have signal.
Smart Switch says that it doesnt support SM-G935FD for initializing and the strange thing is my phone is a SM-G935F not a SM-G935FD (duos) but i'm sure every rom i flashed was for galaxy s7 edge. So one of the roms i flashed changed my phone to SM-G935FD. Am i screwed ? Pls help
If my english is bad pls don't correct me my native language is not english and i'm not using google translate.

I did that already my friend and it didnt work... I think it has to do that my phone thinks i have 2 sim cards and 2 imeis which i never had thats why its bugged and i dont know how to deactivate the 2 sim card function.
Only for some info to you experts out there who want to help me i found out that in the king of nougat rom theres an option which says : "Stk2 - for dual sim variant" i think thats the option that bugged my phone can't i deactivate that with editing a file ? If you guys need more info about my phone i will give you everything just ask me.
Btw thanks for all you guys who tried to help me it gives me hope to recover my phone.
So you only have one correct imei in the imei information and second slot in unknown or you have no imei in both slots?
If you have on correct imei have you tried to turn of second sim card in sim card manager in setting?

Flash back to the G935F ROM of your region, and take your phone over to a repair store, give them the IMEI of your phone and the S/N (they'll be written on the box), and tell them to re-flash them. It seems your EFS partition has gone corrupt, when you flashed the wrong file.
I know how you feel, I did the same thing with a phone of mine once, I felt like crap afterwards, don't worry about it. This kinda sh*t happens to all of us. Just be glad nothing else happened and the other hardware still functions correctly.
Good luck bro, and be more careful next time when flashing.

Technically you can fix it, but you'd require some specialist tools that cost a somewhat hefty amount and usually the only people who keep them are phone repair stores.
No matter how much of an expert one can be, without an EFS backup, you can't restore your IMEI. In older phones like the GS4, if your IMEI was wiped with a bad flash, flashing the modem twice and doing a hard reset would bring it back, unfortunately it's not that easy now.
Anyway, mistakes happen bro. Don't worry too much about it. It's annoying to go to a phone store, but just remember, it'll be a lesson in the future for us all. Always make a backup before flashing, anything goes wrong, restore the backup and you'll be safe.
Samsung service center will be able to see that KNOX is void and it's 0x1, so they might charge extra.
For ordinary phone repair or software specialist stores, they won't really care whether it's rooted or not, they'll just use their tool to flash the IMEI and S/N back to your phone.

[Help][No Sim Card Working][HUGE Issue!!]No service issue and blank imei PLEASE HEL

My brother who lives in dubai used his sim card in this phone but ever since i got the phone in Pakistan ive tried using my sim but i get no service.
My guess is it only works with 4g LTE but i cant try cuz where i live here's only 3g and 2g coverage.
So i started using it as a wifi tablet.
Dialed *#06# and it showed both imei numbers but ever si ce i updated to purenexus 7.1.2 rom it gives me the same service error but dialing *#06# gives nothing but two plain zeroes like in the screenshot. Can anyone please help me resolve this i would greatly appreciate any help regarding this.please help my phone is useless without a sim card.
Screenshots show how it detects the sim card perfectly and gets the number.
-searches for available networks but cant register on a network:crying:

Do the network settings reset, see if it works. if not, install app called LTE Discovery and reset thru it. if still fails, flash stock rom

Random reboots

Hello friends.
I recently purchased a galaxy note 3 SM-N9005 from cex and I rooted it and tried to install a new ROM. But when I install any touchwiz ROM the phone would automatically restart continuously with the sim. As soon as I remove the sim. The phone works perfectly. I've tried to change sim cards but no luck. But if I install any aosp ROM the phone works perfectly. Can you guys find the reason why this is happening? Would be highly appreciated.
Sorry for bad english
Was the phone new?
Imei in the phone matches the imei on the battery label?

No. The phone was used but but the imei matched in both cases
Very strange that only a custom ROM will work. You tried different sim cards from different carriers?

(Problem) SW REV. CHECK FAIL. DEVICE: 2. Binary: 1.

Hello guys!
I have a big problem with my S7 edge (G935F)... The problem begins when I forget to turn off the OEM security and then I did an update to my Magisk root... When I tried to reboot my phone it doesn't pass of the first logo image, meaning that I broke the "security", so I read about that and then I flashed a firmware, an official UK (BTU I guess) firmware and then I flashed TWRP via Odin to restore a nandroid that I did when I bought my phone... It restored the EFS partition/folder and when my phone reboots I had no network signal, no IMEI... I just tried everything (I hope not) and I can't give back my IMEI and my network signal... When I try to patch the certificate to recover my IMEI via Odin in the download mode it says: SW REV. CHECK FAIL. DEVICE:2. Binary:1
I don't know if I explained it because my english is too bad, but I tried, I know that someone else have the same problem than I because I saw it. Do you find the solution? I'm out of my country and I need it so much :crying:
Regards!

Thank you for answer me.
I did it with three diferent stock firmwares and the problem persists (no network signal) I think that is something with the EFS folder, I restored a backup of it but is the same, I have not signal yet, but thank you!
Try clean formatting

Hey brother it happened with me too, unfortunately, I had to format my internal storage to fix this, you need to flash the latest nougat firmware via odin with csc including bl and modem and then start in recovery then format and start phone, remember you would need to put the google account which was previously there in the phone to unlock and complete setup process (very important here)

Thank you! Do you know which Firmware I need to flash? Because I flashed a lot of firmwares and it didn't work! You would help me a lot if you give me the name of the one you used.
Here I have some screenshots of what appears in IMEI and SIM.

Download the latest firmware from https://updato.com (it's fast and reliable) then start in download mode, run odin with administrative privileges, select BL AP Modem and CSC (dont use home since we wish to clean fornat), and in odin uncheck auto reboot option, after the ODIN shows 'pass', disconnect the cord from pc, now you have to be very quick here since our battery is not removable, in order to shut down s7 edge from odin mode, all you have to do is press, volume down, volume up, home and power and as soon as it goes off connect the cord, the battery will show up and now it will be in charging state, after that disconnect the cord, (the phone is now clean fornatted and in off stage) and now boot into recovery to wipe data and cache using default recovery, then reboot phone and then log into your existing google account.
I know its tricky and maybe there's an ez way around it but this worked for me so I'm sharing
SOLUTION, thank you all for your answers!

I tried it at first instance but I could not because my Bootloader was updated to the "U2" version, what I did after that was search the Combination file updated to the U2 bootloader, after a long search I found it.
In resume, The solution is what the OP of that thread says but if you have the same problem like me with the Updated bootloader you need this file instead of the files that are shown there:

You already fixed the problem I guess, you only need to flash the same firmware that your phone had before flashing the Combination file.
