HELP! "Emergency calls only", but i've tried all

Hello, in december, one day suddenly i was in the car and i was driving through a zone with a low signal, from that moment, my S6, losed the signal, and died (?). Today, are 2 months that i don't have signal. I have also tried different sim cards, but nothing. After i had this problem, i did a factory reset from the phone, i put a different sim card in the phone and it worked, i saw the carrier, and i received the sms with the internet configuration, after 1 minute i lose the signal, after that, again, the phone didn't wanted to receive signal. i also tried with a romanian SIM (i am from Italy), but nothing, i see the R near the signal bars. if i go in settings and i search the network operators, the phone finds all, but i can't connect (the SIMs in another S6 works). my phone originally had a brand ROM (WIND Italy), so first through Odin i re-flashed it, but nothing. i also tried to flash the fw with no-brand, but nothing. I've tried absolutely all, i did reboot, flight mode, factory reset, Odin, changed sim, i don't know what to do. my model it's the SM-G920F, i have the 5.1.1, i never did root or flashed custom ROMs, the IMEI it's okay. if i go in ''SIM card status'', in Signal strength, the signal moves, but in Service state it displays "Out of service". The curious fact is that, before this happens, the phone worked for 6/7 months normal, without network problems, after i started using this operator (WIND), after a few weeks, it started that crazy story. what can i do? :crying::crying:

thanks, should i wait for the italy Marshmallow update or install the other already existing? because here in Italy, Vodafone has released the update, should i install this one, or maybe the UK or another? i am on the no brand fw.

Flash any stock 6.0.1 from Sammobile(it won't change Your knox counter) and if it doesn't work take it to Your carrier seller or samsung service repair center. They both will either fix it for free of give You a new one. Mostly odin reflash fixes all problems.

okay, in past, the flashes i did, i just flashed on Odin without doing factory reset (from system or recovery), or deep clean, should i this time? because updating the fw, it updates the modem part, so i think that i don't have to reset it (?), i don't know, also after i did the update, if the network doesn't works, can i downgrade back to 5.1.1 simply flashing again the fw?

Just make sure you are updating the right rom for your model...dont use another rom for another model...this can get you problems after some times...lets say you flashed vod rom on XEF this will give you ptoblems later mybe loosing imei or signal....and if update ota you get updates for VOD not XEF...its just not right...my advice update right rom for you model look sammobile

i think the problem could be the antennas inside...but i guess the fix is to replace the entire motherboard and that is expensive

i don't know, but it's really strange, because when i updated to MM, i had signal for 1min, but i rebooted it immediatly thinking "if it works, works even after the reboot", but it doesn't. i'm sorry, i hope you will resolve your problem

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.

S6 not recognizing SIM card (No Service)

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

Problem with flash Stock Firmware Nougat. No signal, only emergency Calls.

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.

G930FD keep restarting itself after nougat

Guys really need help here, I just got a used indonesian g930fd (strangely it shows g930f on phone info) which keep restarting itself after upgrading to nougat (OTA). Also even if I already "power off" the phone, it still restarting (or booting?).
I've tried to factory reset from recovery, still keep restarting. Btw at first factory reset, somehow data partition got corrupted then second one success. Also when my data partition corrupted, the phone doesnt restart/on by itself like I mentioned before, so seems firmware related issue instead of hardware.
I also tried to go to two samsung service center, because first one somehow tell my imei is from singapore and second center tell mine is fro arab (wth) so I can't claim warranty eventho still below 1 year.
My question is:
1. Does reflashing stock (7.0) firmware will fix it?
2. Why phone info show my phone model as SM-G930F instead of G930FD?
3. Is it possible to change Product Code? rite now my product code is definitely Indonesian (SM-G930FZDUXID), originical CSC blank, everything else XID / Indonesia . I kinda have doubt now because two service centers tell different country, also sticker on back cover somehow tell its G930F, and print one on glass cover G930FD
Mind me if these question alrd asked before, but I already tried to search and googled everything and Im still lost here.
here's my firmware information from *#1234#
AP: G930FXXU1DQE7
CP: G930FXXU1DQD7
CSC: G930FOLE1DQCV
Model: SM-G930F/DS

Hi mate
Well mate , F and FD models have the same hardware and and use the same firmware , only difference is the SIM tray , they are different to fit one or or two sim cards depending on the models.
The model number is written in the build.prop ( do not know if somewhere else) if it only written there phoneinfo can be fooled , you can double check it by checking your IMEI at this site or other similar
http://www.imei.info/
It will tell you to what phone that IMEI was issued to. Check also with phoneInfo if the phone is original or refurbish
to your questions:
1. Does reflashing stock (7.0) firmware will fix it?
Is a good chance it will, if there is no hardware issues
2. Why phone info show my phone model as SM-G930F instead of G930FD?
do not know , check by your IMEI to see what the real model is
3. Is it possible to change Product Code? rite now my product code is definitely Indonesian (SM-G930FZDUXID), originical CSC blank, everything else XID / Indonesia . I kinda have doubt now because two service centers tell different country, also sticker on back cover somehow tell its G930F, and print one on glass cover G930FD
You can flash any F firmware with the desire CSC code , just download the firmware and flash it using CSC and not home_csc

Thanks for ur response! It's still original from phone info, now not tho since I already flashed new firmware.
Things that I already did:
1. Flashing two same 7.0 nougat for Indonesian version (updato and sammobile)
2. Tried entering recovery mode while charging to check if battery dead, result can't enter recovery mode means battery should be fine.
3. Checking serial number with Smart Switch somehow tell me it's from Arab. I can't restore tho since it keep restarting.
And restart issue still there. One thing for sure it does heat up everytime. While on odin mode, it never restart tho. I still can't find the problem
Is there chance for any other hardware failure somehow aside battery? Thanks!

Hi
It's still original from phone info, now not tho since I already flashed new firmware.
The original check in phoneinfo is regarding the hardware , it has nothing to do with the firmware also you can flash a different firmware to your phone and would be still original
1. Flashing two same 7.0 nougat for Indonesian version (updato and sammobile)
What files did you flash?
2. Tried entering recovery mode while charging to check if battery dead, result can't enter recovery mode means battery should be fine.
Not sure what you mean ...if you cant enter recovery while charging means battery is fine, that makes no sense, i doubt your issue is battery
3. Checking serial number with Smart Switch somehow tell me it's from Arab. I can't restore tho since it keep restarting.
I said check your IMEI to see to what device was asigned to , to see if it was assigned to a G930F or G930FD
Is there chance for any other hardware failure somehow aside battery?
motherboard...but if before of OTA was working fine i would think more in a firmware issue
