Galaxy S8 not picking mobile network - Samsung Galaxy S8 Questions and Answers

So I bought a used Galaxy S8 (SM-G950F) from the aftermarket. Upon doing a factory reset, the dreaded "only official released binaries are allowed" message started showing. Tried everything including wiping cache, factory-reset (multiple times). Finally found a Youtube video that showed me how to download official Samsung firmware from sammobile.com and install it using Odin. The video also suggested that I should download the "BTU" version from ANY country if I had an F model (which is supposedly international). So I downloaded the one titled United Kingdom (BTU). FWIW, the exact firmware file name was G950FXXS9DTEA_G950FOXM9DTE1_BTU.
I followed the steps in that video and viola, phone started like normal. I restored my account, got back everything working.
The only problem that I'm now facing is that my phone does not recognize my mobile sim. Earlier it was simply showing ? symbol for network. After some restarts, tray eject/inject Now it is now showing the signal bar, but it is grayed out. In Settings > Mobile Networks > Network operators, clicking Select automatically shows error "Unable to connect. Try later.", whereas clicking Select manually shows "Error while searching for networks". I have searched around quite a bit and it seems to be a well-known issue, but the posted solutions (fractory reset, sim cleaning, switching to 2G mode etc) are the things that I have already tried.
Is there anything else that I should try before contacting my network operator? Specifically I'm suspicious about the firmware that i have downloaded. Can it be that United Kingdom (BTU) is locked for the networks that operate within UK only (I'm not in the UK)?
EDIT
------
Further investigation revealed that this phone's had been flashed with fake IMEI number. The number that I see in *#06# is totally different from what is printed at the back of the phone, which is what is probably causing the sim problem I mentioned above (local laws require IMEI to be registered with authorities for a device to be able to work).
Even a factory reset and wipe didn't restore the original EMEI number. Is it the end of the road for me? Or can I restore the original EMEI somehow?

An easier way of restoring lost IMEI (GT-I9500)!

Hi!
I just like to share something I have discovered during the time I was already going nutts when I discovered that my phones IMEI was replaced by another set of numbers. It all started when I flashed a Firmware XXUBUBMG1 (Movistar) that I downloaded. It was for GT-I9500, the same model as my phone. Everything went well, then I noticed this problem when I decided to call the Customer Service Number of my SIM, the device is telling me that my phone is Not registered on network. Then I decided to check the IMEI and to my horror, it was replaced by this set of numbers, 004003150000, which is not my phones IMEI. Then I decided to look for answers over the internet. But before going further and going thru all the trouble of starting from scratch, an idea came to my mind. I decided to try it out before doing anything else. And whoalah! My phone's IMEA is restored! I can make calls again and connect to the net via Mobile Data again.
Anyway here is the solution that I came up with. If anyone else had tried this before then I give all the credits to him for fixing his phone. :laugh:
1. Download a firmware that is intended for your phone's model number and the region where you bought your S4. Mine was bought in Saudi Arabia, so the firmware I got was for KSA. It also applies for the GT-I9505.
2. Enter Download Mode and flash this firmware via Odin on your PC. I didn't do any Wipe or Factory Reset during this time.
3. Root and install any custom Kernel or CWM Recovery on your phone if you are on this setup. Otherwise leave it as it is.

[Q] stock 4.4.2. No service, data works fine

Dear all,
You are my last resort. I've been trying to find out how to fix the problem, but no success...
My Note3, 9005 (bought new, without contract), has never been rooted or modified in any way. Current version is 4.4.2. IMEI is fine. Well, I am a regular user, who keeps updating the phone, when there's an update from samsung OTA.
I've been using the phone for 1.5 year, everything was fine. I recently switched the operators (Belgium) maintaining the same phone number. And there the problems started.
Very often I get "no service" message, although data connection works fine. I tried automatic and manual selection of the network, but the problem remains. When I select automatic network, I get the message "registerred on network", but "no service" sign remains and get no call connection (data connection works fine). When I select the network manually, I get a brief message "registerred on network", but still no service and then "the network is unavailable"/
I contacted the operator, they claim that my account is fine, they see no problems on their systems. The interesting thing is, that other operators SIMs work fine with my Note. Apparently, it is only my current SIM which fails to work. I have two different phone numbers SIMs from this operator and they both have a frequent "no service" in my Note. I have also requested a new SIM, which again did not work... The same SIM works fine in Sony Xperia. I have also tried that same SIM in galaxy s3 (LTE). And there was again a problem with connection, i.e. no service, but data functions fine. I have also tried different modes (3G, 4G), the problems remain. It looks like it is the problem with samsung devices.
This is the time when I really need the phone for my work...I keep failing my clients because they cannot get hold of me. And changing the phone number and operator would be very inconvenient at this time.
Is there anything I could do to fix it?

try to flash stock firmware of your country via odin. i hope its work.
Nico, many thanks!
I understand my phone was brought from the UK. But currently I am in Belgium. Could you please tell me, what country firmware should I use, what specific firmware I have to flash? (I would appreciate if someone could refer me to a download link...I am not very good with these types of things, I am afraid to mess things even further...)
rooted, reinstalled stock 4.4.2. Now when making a call, the network dissapears and connection dissapears and becomes "no service", therefore the problem remains. data connection works fine.
guys, please advice, what can i do to fix it? should i go for other ROMs (not stock), would that help?
i've read about ariza patch, but did not understand whether it is available for note 3 4.4.2.

Joku, thank you very much for your reply!
But I think I did exactly what you have recommended in the first attempt - flashed the stock version. Please see the pics of kies and suggested sammobile firmware attached. ...But "no service" problem remains. Althoug, I must say, it goes away from time to time (better than it was without reinstall). Maybe I should go for other country firmware (for example Belgium, where I am currently based and where the problems persist)???
After reinstall my firmware is:

All seems ok. Make a thing:
1. Backup your data and factory reset your phone (Pic attached)
2. Tell me if you have service then.
This is obviously a carrier issue as you stated yourself other carriers work fine. You can waste your time throwing things at the problem, but I'm highly confident it's not going to be fixed by anything you do.

It does sound like a provider problem...
Try a factory reset first, just to be sure. Best do it through recovery, so you can wipe the cache as well.
Does the no service happen everywhere? Or just in specific places?

Thank you all for your replies.
The problem is that the same 'no service' SIM works fine in another phone (sony xperia), the provider will claim that it is note3 fault.
I did factory reset after I reinstalled the stock version.
It looks like ' no service' appears when the phone changes the cell/network towers when travelling from one location to another. .. But I can't say that it is always the case. I just don't find any logical reason to fully explain that.
The weirdest thing is that data connection works fine always.

It is probably related to the way your provider does the 2G/3G/4G band allocation and switching - what provider is that?
You can also try to set the data to "3G only" vs "LTE/3G/auto" and see if is any difference.
The provider is Base (via virtual network provider).
I've tried everything, including changing to 4g, 3g, etc. Nothing helped : (
Should I try flashing different modems? The question is, which versions should I go for. ..?
updated to lollipop. no changes
I still haven't solved this issue. I just updated to lollipop (via CrashRom), the problem with "no service" remains.
Is there anyone with similar problems, who was able to find an answer? What else could I try? Should I try flashing different modems? Could anyone help me choosing which modems should I try?
pleeeease.... : )
anyone please?
can I try flashing different (older) modems? would that mess up my curent rom?

Check this post for downgrading from Lollipop to KitKat.
Regarding to "No service" problem, go to the ServiceMode MAIN MENU and try NV REBUILD.
To open the ServiceMode MAIN MENU:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#27663368378# > 'Launch 0'.
- If you don't have root, open the dialer > *#0011# > Menu - Back > Menu - Key Input > Q0 > wait... until it appears
iritoi said:
firstly, many thanks for your advice to rebuild nv.
i did as you explained, but... it did not help.
i went through all of the options available, flashed stock firmware, flashed various roms. nothing helps. what's interesting that i have call availability (service) for some time, but when i move to different area, the service dissapears and i have to turn on/off airplane mode. and this happens with specifically one provider (mobile vikings/base - belgium). if i insert the other provider sim, note 3 works fine.
my imei is ok.
pleeease help me to fix this problem. what else can i do? is theo nly option left to change provider?

Currently I have no idea.
Your best bet is flashing back to original stock firmware.
And try to check your SIM card in your Note 3 by follow these steps:
In the ServiceMode MAIN MENU, select DEBUG SCREEN > SIM INFORMATION, you will see 3 options. Select every option, capture screenshots and post it here more more checking.

In the band frequency it says "unexpected value". Maybe that has something to do with the problem... Or am I being listened by secret services : )

Mine are the same.
Except for the 1st screen: SIM Phase = 2; SIM voltage class = 3V.
The 2nd and 3rd screens are the sme.
is there a way to see the reason why the network is being disconnected via service menu?
...because when i turn airplane on/off, the network comes back. but when i dial the number it disappears right away with the message "network not available".

[Q] G900F won't make or receive calls

Hi
I have searched the forum beforehand and can't find a post with the same symptoms so...
I have just bought an S5 which will not make or receive calls or texts, although my mobile data works fine!
The guy I bought it from said he had it brand new and sealed, and used a Giff Gaff card for a few hours with no problems before the issue developed. I'm using Virgin. It was apparently from new, a Three network phone but did not appear to be locked to their network.... no unlock messages appeared when my SIM was inserted, it all appeared to work until I tried dialling!
I get a good signal and all the indicators are that the system is connected and functional, but when I dial any number the phone dials briefly then shows "Call ended". Texts just fail after a short while. Emergency calls work OK so the radio seems fine.
From the wonderful Phone Info app the following are installed:
Bootloader version: G900FXXU1BNL9
Baseband version: G900FXXU1BNL9
PDA version G900FXXU1BNL9
CSC version G900FH3G1BNL1
Product code: SM-G900FZBAH3G
I have tried the BOB7 BTU firmware via Odin and this worked ok but didn't fix the problem.
I also tried to downgrade to 4.4.2 with both the Three firmware and the ANG2 BTU firmware. Both just cause the phone to hang at the splash screen.
The serial number, IMEI number and the "refurbishment" check all show the phone as genuine.
Knox is still sitting nicely at 0x0.
Looking through the service menu settings nothing obviously jumps out as a problem but it does seem to be some sort of SIM lock.
Phone info shows the manufacturing date as 2015.01.03 so should be in warranty so I'm holding off rooting it as long as possible
I have scoured the internet and found a couple of others with the same problem but no helpful replies to their queries.
Any ideas anyone? Thanks guys
Try a Giff Gaff SIM in it, if that works, you have your answer
If you have upgraded from 4.4 to 5.09 through Odin as I did with mine which is Generic BTU the phone calls and texts would not work after the update so I did a factory reset then flashed the BTU firmware again did another factory reset and the phone has been fine ever since.
One of my friends got an S5 just before Christmas on 3 Network he was told by them that they no longer sim lock their phones how true this is I don't know but he tells me that's what the sales person told him, but he now has Generic BTU firmware on it not the original 3 firmware, he had to do a factory reset twice before his worked properly
So it may be worth trying bt flashing the BTU firmware again (BOB7) then doing a factory rest, flash the firmware again after that and factory reset once more then see if it works properly
Thanks for the quick replies.
I have flashed the BOB7 and BNL9 firmware several times with factory resets... no difference. I have also tried to downgrade from the original 5.0 to 4.4.2 (UK S5 didn't get 4.4.4 as far as I'm aware) but the phone hangs on the splash screen and I then can't boot into recovery.
I am waiting for a Giff Gaff SIM to try but tried my mate's contract Three SIM yesterday and again data was usable but no phone or texting. In fact it was worse than the Virgin SIM as it displayed no network whereas the all the Virgin info was there as it would be on a working phone.
I originally thought it was a faulty radio but as emergency calls work I have ruled this out.
One thing I've noticed is that in the Service menus there is sometimes the message to "Pease reboot" - an obvious typo but not something I would have thought Samsung would have overlooked. Maybe it's a dodgy clone. Anyway of knowing for sure?
One other thing that may or may not be relevant. In my working phones with the Virgin SIM, the Service menu shows the "Speech Ver" as "FR FR FR" as does the dodgy S5 when it has the Three SIM in it. When I put the Virgin SIM in the phone the "Speech Ver" changes to "AMR, EFR, FR". The "FR" I believe means "Full Range" so is that a contributing factor?
I've attached a screenshot of the phone menu with the Three SIM inserted.
Thanks for your help so far guys, it's much appreciated, this has me stumped.

Thanks for that mate, mine compares ok with yours, particularly the "About" status.
I have now tried 02, Three and Giff Gaff sims as well as my Virgin sim. Same problem, can use mobile data but no calls or texts.
reflashed 3 more times with a factory reset after each, same problem.

S7 Edge to "Emergency calls only" mode forever

Hello.
I am facing a frustrating issue with a Samsung S7 Edge G935F that came into my hands from a client of mine. It has the usual issue with the “Not registered on Network”, always in “Emergency calls only” mode. I have tried everything I can think of and searched for in Google and nothing worked. The phone is from Romania and has the Romanian firmware 6.0.1 (open carrier, not locked) and he wants to use it in Greece.
Here is what I tried:
-Flashed older firmware with Odin, just in case
-Flashed the latest again (6.0.1 December 2016) with Odin (BL,AP,CP and CSC file, not Home_CSC)
-Checked for updates OTA, no newer updates than those flashed
-Tried multiple Romanian and Greek official firmwares and tried to wipe data and cache
-Turned airplane mode on and off multiple times
-Searched network provider manually in mobile networks settings
-IMEI and baseband are not corrupted, they are shown as they should
-Checked IMEI if blacklisted or carrier locked. It is clean and in open carrier, not locked
-IMEI is not fake, cross-checked with back cover glass and battery label
-Brand new SIM
-Tried another SIM of different provider
-Cleaned the sim socket with isopropyl alcohol
-Reflowed the ICs associated with radio signals
-Did not find any signs of dirt or water on the logic board
-I have NOT tried to root and flash a custom firmware because I do not think it would change anything
-There is no problem with the network coverage of the 2 sim cards I used in my location
Nothing! I believe it must be a hardware problem but I wanted to triple check with you guys.
The CSC value it has now is G935FOXX1BPH1, the Romanian one, just for the info. The Greek one I used previously during the multiple tries, was G935FEUR1BPH1.
Any idea will be appreciated, I will try it!
Thank you in advance.
If the phone is giving an emergency calls only message, it means it can see and use at least one network, which suggests it's definitely not a hardware fault, rather a network compatibility issue perhaps? What network are you currently trying to use it on?

I am trying to connect to Vodafone or Cosmote. I just tried to call 112 emergency number and it tries to dial for 10 seconds, then it says out of service area and drops. i believe the emergency calls only message is kind of "by default" when no network is available, not the actual emergency mode.
Let me note that when i search the networks it finds the providers available.

Axon 7 Mini not working oversees

Hello, hoping someone can help out, I bought a AXON 7 mini hoping to use it in Iraq, but it does not seem to want to register on any network outside the USA. In the USA I was using a Tracfone T-Mobile SIM and the phone worked great. As I traveled across Europe the phone would not connect to any networks (Germany and Turkey), I figured it was just the SIM not allowing roaming. When I got to Iraq I purchased a Korek SIM and still no dice. I phone sees two networks but will not show any service. I have tried SIM cards from other phones with active service and still nothing. I have even tried a SIM card from ASIACELL and still no dice, it sees the providers but will not show service on the network. When I click "automatically select network" the phone response "registered on network" but still no service. I have tried the usual reset all the way down to a factory reset.

Flashing EU ROM
Could I safely flash the EU Firmware located here, https://forum.xda-developers.com/axon-7-mini/development/firmware-stock-firmware-t3696538 safely to my device. From what I have seen this may fix the problem.
Thanks, Jeff

Phone now seems to be fully functional with aid of a lot of reading an testing. I can also replicate the issue consistently. The original issue seems that the pervious owner, or ZTE set the operating band to "United States." Once this has happened the seems to be locked to USA networks, even though it still sees the other networks. Using *#*#4636#*#* method, you can try to change the band, but only 2 options are there "800 cellular" and "United States," I tried to change to 800 but get the response "unsuccessful." So for the fix!
Thanks to all the hard work here, I was able to install the boot loader unlock update for my phone found here: https://forum.xda-developers.com/axon-7-mini/development/unlock-official-bootloader-unlock-t3690496
I then proceeded to install TWRP, backed up the entire system, and then installed Linage. Then used *#*#4636#*#* and the band now had a third option of "Automatic," selected that and bingo, service in Iraq. Recovered the phone with the backup and the fix stuck. Of point in Lineage there is five options in the band selection, 2 options are duplicates (USA and Auto), I assume for each SIM, and you have to select both autos otherwise only one SIM will work.
This probably could have been fixed with a ROOT application that allows you to enable additional bands, but I was never successful in ROOTing my phone.
