I have really made a mess trying to fix it myself.
I will write the current status and at the bottom what I've tried so you can skip
Model: sm-g920f
IMEI: 359845066450254
sn:RF8G41WR1SW
Android version:6.0.1
build #: XtreStoLite Deo Mod v.3.3 - DPDP
Baseband:G920FXXU3DPDP
Kernel version: 3.10.61-7884513 [email protected]#1
22 Apr KST 2016
now the sim card works in other phones and when I remove it the device registers it is SIM CARD REMOVED but when I put it back in nothing happpens, and mobile networks settings is gone
*I started in stock 5.1.1 (MADE NANDROID BACKUP OF EVERYTHING INCLUDING EFS) and flashed twrp via odin > (everything still working)
*flashed XtreStoLite 2.4 (5.1.1) via twrp > (everything still working)
after several months
*flashed new 6.0.1 bootloader and modem via odin and tried to flash XtreStoLite 3.0 (6.0.1) via twrp > got stuck in bootloop...
*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin
*I flashed XteStoLite 3.3.1 (6.0.1)
*I tried restoring from the first nandroid (stock 5.1.1 from the begining) and got stuck in bootloop again.
*reflashed XtreStoLite 3.3.1 (6.0.1) and tried restoring only the efs. still doesn't work.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

After installing a custom ROM on my galaxy s6 it would no longer recognize my SIM card. I did wipe every option in TWRP recovery before flashing the ROM which might have something to do with the issue. The phone states "No SIM Card - No Service" in the top left of the lock screen, it also wont let me call any numbers to edit things in the phone. I have done some research and it sounds like I have wiped the sim and lost the IMEI/EFS data and therefore no longer have access to my sim. I was wondering if there was any possible fix or should I just send it off to Samsung to get repaired?
Did you back up the EFS partition, and put it somewhere safe? If not, you have a paperweight.
Repair won't be covered under warranty.

Unfortunately I didn't back up the EFS partition. Situation is looking bad. :l
Try dialnig *#06# and see does it shows IMEI and sn, alo try *#0011# select stack 1 and check whether IMEI is OK, or NG.
Also what does it say in phone settings under baseband? Do you have mobile networks menu in settings?
You can try Smart Switch emergency initialization with sn of the phone if IMEI is ok (it will install latest stock fw for your phone) and see if that helps.
When I typed in "*#06#" The SN number was shown however the IMEI number was not. When I typed in "*#0011#" There was nothing but blank spaces separated by grey lines, I tried selecting row 1 however nothing happened. My base band version is "Unknown" listed under settings. I do however have the network settings listed in settings. In Smart Switch when I try to run the device initialization it states that my s6 "doesn't support initialising". I have flashed three different downloads of the stock rom to my phone using ODIN and have had no luck with any of them.
well Smart Switch always says that S6 is not supported, but initialization can be done anyway, just dont connect the phone until it asks you to do so, instructions below:
http://forum.xda-developers.com/galaxy-s6/help/how-to-smart-switch-emergency-t3383448
What is your model anyway, do you know which region fw was originaly on the phone, and which sv rev is shown in the download mode?
does in recovery mode says anything about DRK?
Unfortunately Smart Switch says that "'SM-G920F' does not support initialing. Please contact out service center." Even when I have entered the correct S/N and device model, as well as not plugging in the phone. My device model is the SM-G920F. I don't know the original region FW that was originally on the phone, however it was purchased in the UK and that is where I am have been ever since I bought the phone. The SWREV is: "B:3 K:2 S:2" in download mode. I currently have TWRP recovery installed so is there a place for me to search for the DRK in TWRP? Or should I re-flash the stock recovery using Odin?
that is weird, I reinitialized my g920f many times without any issue. DRK error is usually shown in stock recovery. does the phone boots up with stock fw, and are you using any custom kernel?
i got the same problem when I flashed xtrolite and alexis custom ROM on my S6, both ROM after flashing I got no service.
But I did a full stock backup in TWRP.
baseband unknown means that there is a problem with modem part of fw. and I dont know what fw you flashed. you said that you tried to flash stock, but it doesn`t work, but a little more details would maybe make a difference, like which fw, and what exactly is happening, what does about the phone menu says.
So far, since baseband is unknown I would try to flash modem fw with odin (for exact fw that is in the phone). before that usb settings should be set to CP, by dialing *#0808#
or if you decide tu run custom fw, you can always try asking in that rom thread, maybe someone already had issues like that with that rom and fixed them, or the developer of that rom can help fix it.
Boot your s6 to download and flash stock rom via odin from samsung it maybe work
Hi Guys
First of all, i´m sorry my english is not very good and i have to use a Translator.
I recently bought a used SM-G930F. The previous owner had flashed before so although everywhere says SM-G930F in settings in "model information" says "SM-G930FD". Also when a SIM is inserted the "DualSIM Administrator" appears. Had Mashmallow installed and worked perfectly.
I wanted to try flashing the new NOUGAT BTU firmware stock. I did it through ODIN. The process had no errors. When the phone restarted I see that it has no signal. It recognizes that you have a SIM card inserted but "emergency calls only" appears.
The IMEI was not deleted.
Immediately I downloaded a stock firmware from my country ARGENTINA to go back to MARSHMALLOW and I installed it but the same thing is still happening. Then I tried to download another stock firmware from my country and my operator CLARO ARGENTINA, but the same thing is still happening.
I read in forums that the problem may be the modem, but I understand that is modified in the box "CP" of ODIN when flashing.
I honestly do not know what else to do. I also do not remember what firmware I had before doing the whole process.
I understand I should have backed up everything but I did not.
So I ask you please if you can help me.
Thank you very much

try flashing the specific modem and bootloader of your phone. you might want to try mashmallow modem.
You say I try flash only the modem and bootloader that come included in stock firmware from other countries? Must I only check the boxes "BL" and "CP" from ODIN? Thats correct?

I also tested Firmware flash from several countries in America and others, for example Chile, Colombia, Brazil, Mexico, Germany, Portugal. I also tested with some G930FD firmware from Vietman, Singapore, but there was no case. The only thing that stands out is that with Vietnam although no signal, "allowed" the band 4G, did not allow it in all previous cases, do not know if something to see.
u have any issues with wi-fi?? it looks like a modem problwm to me..
Try flashing the stock rom back with the samsung kies program so it will flash back the original stock rom that came with the phone and see if you then have your connection back. If that works then try to flash the BTU.

Hi!
No, the Wi-Fi works fine
Phone is likely IMEI blocked (reported stolen)
Is it possible? I'll find out and tell you. Thank you

I have Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.
Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !
First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?
Bump.
Hi guys. Hope anyone of you can help me.
So I've bought the dual sim version from Dubai. Flashed Custom rom, flashed nordic CSC file. Everything was working fine for months.
No while I'm in Turkey. I inserted a second sim (turkish one). Phone asked for restart cuase it's detecting new sim.
Restarted phone and now I get red font error at Samsung logo. "Custom binary blocked by frp lock"
I can't boot in to recovery mode either. This is very strange. What could be messed up? Huh
Any help please. I would love to save my data before wiping everything!!
Let me know! Appreciate it!

Not working. Cause I'm stuck at the Samsung logo. Can't log in with my google credentials!!
BTW it says FAP lock not FRP.
Also how could this happen? Why did it get locked?
Any help please. I'm stuck in Turkey without my phone!!
You have to go to updato.com and download your firmware. Then Odin flash it, then go to developer settings and check off OEM unlock.

Recovery Mode?stucked up... You can re-flash the ROM.This time Dont go for Custom Rom
Use Offical Rom Provided By Samsung...Cheers
Different Custom roms aren't built accordingly as the offical work fines and smooth:good:
Guarantee you flashing stock rom will not work.
I've been stuck in recovery and download mode and downloaded all the official samsung firmware for my phone, 100% exact and 100% correct firmware.
Been trying for days and days and days.....all flashes ok, but simply reboots to android recovery saying same old SHI*
Which is:
something along the lines of DRK not installed and to install ENG boot or binary.
I've downloaded from coreect site, efinitely the correct firmwarefor my phone model and carrier etc etc....nothing works.
tried different versions of odin etc.
Nope, nothing.
I've got a BRICK!
Took my phone into Samsung store today, they looked at it and basically said, warranty void - only way to fix it is to fit a brand new board!
getting it back Tuesday, but costing me £250 ! ! ! !
