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.

Hi,
I recently got a SM-G920F off the internet and noticed it was running android v.5. There was no update option available in the usual place so I tried to update to Marshmallow manually with Odin and it failed during the update process.
I've now noticed that even in Odin Mode, it's showing as a SM-G920P. As a result of this, only US (SM-G920P) firmware installs (everything else just fails) which isn't any use as I'm in the UK! I've tried to reset using smartswitch but it doesn't even recognise the serial number. The back of the phone states it is a SM-G920F and I was previously able to download apps to confirm that the phone isn't a fake.
Has anyone else had this problem? I think I just need to configure the phone to be a SM-G920F again and it will take the firmware but I can't find a way. Have tried editing the prop.build file in /system but it's still saying it's a G920P in Odin mode. Any ideas/help would be appreciated.
Cheers.
where did you get the phone from? for me it sounds like it is a g920p. also your seller may have replaced the back cover of your device. in this case, the produced backcover will always show g920f because its the most common version.
also, editing the build.prop and other system files to show g920f firmware won't change anything. some custom roms even show g935f (galaxy s7 edge). but you're still not able to install a galaxy s7edge firmware over odin.
it's like putting an apple sticker onto a windows machine. it shows "apple" but it is still not a mac.
Thanks for the reply, Tim. I got the phone from an eBay seller in Hong Kong. It definitely was a G920F as I took a few screenshots before the upgrade and they show it was running the G920F version of Lollipop before the botched upgrade.
Cheers.
ok, could you possibly post them?
Sure, Tim. Both of these were taken before it all went wrong...
I'm unable to post pics on here so have placed on imgur dot com/a/Izrw7
Thanks again.

really appreciate the help
Hi !
The correct rom can be found on the samsung`s firmware download website , chose the one for your exact variant. It can be manually flashed using Kies or Odin
The problems you have are not firmware related , when flashing kernels , check the thread for compatibilities and issues
God luck !
Hello guys,
I have been stuck in this for about a week now. Have read tons and gone through a bunch of videos but still stuck. I will greatly appreciate any help.
I was trying to unlock a Samsung Galaxy J3 Luna Pro SM-S337TL (GP) Tracfone.
Downloaded and flashed the combination file using odin but after booting into the binary it show:
CP Crash
Upload Mode
Secure NV read decrypt fail.
Because of this I am unable to complete the network unlock. After several trials I flashed the 4files and got back into the phone, to discover the IMEI and Baseband are gone.
I have tried to download and flash many versions of the Stock ROM for model and even used KIES to find the corresponding Firmware version using the Serial number, but I can't seem to get them back.
I didn't backup before I started. Big MISTAKE.
How do I fix the device to be be unlocked and get the IMEI and Baseband back? One step at a time please.
I have a Galaxy A51 (SM-A515F) and I tried to change my csc from OJM_MID to OXM_BTU, but whenever I flash it correctly a few things happen:
1. "starting Android" is in Russian
2. the default language is Russian
3. Russian bloatware
4. and when I check the csc it's OXM_SER (Russian)
5. And when I reflashed to OJM_MID it's now OJM_XSG (UAE)
if my stock firmware was multi csc OJM can I only flash firmware from the group?
and is there a reason why flashing firmware with BTU csc is somehow converted into Russian?
Note: the site I used to get the firmware was [ samfw.com ]
Update: the phone has been boot looping / freezing constantly even before flashing a new firmware so it's pretty much dead. no need to help me anymore.
Im planning on getting the A52s 5G
