Hello boss just now I checked imei no underneath the battery and match it the imei comes on screen by typing *#06# they are different from each other I think imei is corrupted now I tried it with z3x box to repair but it's no support for s5 .

Then only installing a new motherboard will get you a new imei number/EFS folder imo.

my galaxy s5 same problem
when calling a number show "not registered on network"
and after restart is ok
my imea is : 35231106103850/01

I have an issue with my s5 sm-g900w8 6.0.1 and z3x unlocking. I rooted the phone and flashed the 5.1.1 modem so z3x would unlock without errors. I put in my freedom mobile (used to be WIND) sim card and it was working for a bit. Then I'm not sure why but it stoped working. Tried unlocking again but no go.. tried other Sims and tried wiping reflashing everything but nothing works. It just says unregistered sim but my voicemail and phone number shows up but can't select network or auto select. What can I do? How do I get to that menu where I can change bands and all that stuff? Any help would be much appreciated thanks in advance guys.
-- update --
welp, such a noob move by me.. (FACEPALM) the darn thing was blacklisted! how or why did i not check this before? oh right cuz it worked when i popped in my freedom mobile sim! i made a few calls and send a txt to verify the unlock worked. when i got home and put my friends chatr sim in it didnt work, either sim. just for clarity reasons could someone explain why this happened? did this also happen to you? just flash combo write cert flash stock done

Would be possible to convert 935F into dual sim?

Hello everyone,
I was wondering if it's possible to convert the single sim model 935F into dual sim model by changing the firmware or by any other way?
Thanks in advance.

Nobody knows if the model G935-F can be used in some way also in dual sim modality?

Only the 935FD, you cant change the phone's hardware

Which hardware do you mean? it´s identical!
Even dual version 935FD uses ONLY one Radio module!!!!
That`s why I support the quastion what should we do or modify to make 935F accepting 2 SIM cards?
I have read on 4pda.ru that dual sim slot from 935FD version does not help.
I can not believe that Samsung uses different SIM slot on both devises.
Who knows anything?

You can't believe Samsung would use a cheaper part on the 90% of phones that don't need the more expensive part?
Your beliefs don't matter, the sim slot is very likely different. Dual sim slots cost more then single sim slots, and since the two are the same size it would be easy to just make a production run using dual when stock gets low.

I have a dual sim tray on order. As soon as it arrives I will be flashing the dual sim firmware to test if it works.

If you check the tear down videos , the motherboard , which also hosts the Sim hardware have the specific model number printed on them, so I'm guessing that you will not be able to adapt the G935F to dual sim. Let's see if CuBz90 proves otherwise.

The single and dual sim firmware is identical, and you don't have a second imei so it wont work.

What makes you think its there? They sold like 10+ million s7's, you think samsung put 2 imei's in all the phones? Doubt it.

http://www.noreplied.com/how-to-ins...d-and-microsd-card-in-samsung-galaxy-s7-edge/

The hardware between both phones appear to be the same (minus the SIM tray), the difference is software related, there is a flag in the csc that defines whether or not your device is single or dual sim, changing it by modifying the value in csc using root privileges (or perhaps by flashing a dual sim CSC ?) and factory reset the phone would, in theory enable the dual sim feature, I am however unsure (it is unlikely) that the EFS contains a second IMEI for your phone. (you would easily be able to tell if you enable the flag in the csc, restore the phone to factory settings and type *#06# in the dialer), if your second IMEI (should your phone still function after the modification) be anything other than 0s then it might just work.

any news here?

I have received the dual sim tray but liek @peachpuff said, I do not have 2 IMEI so not bothered wasting my time trying it.

Im using a sprint s7 edge that I froze apps on before inserting the sim card and in the activity manager app if I go to the 2nd phone icon then down to network settings it opens the sim card settings. It shows sim 1 and sim 2. My csc code is xas instead of spr because of disabling packages prior to activation. Your theory is correct mathieulh

So, did you check if you have a second imei which would allow you to insert a second simcard?
Gesendet von meinem SM-G930F mit Tapatalk

I don't believe it would work, but so we can get a real answer,I will try this tonight and post with the result so then it's settled. But I really don't expect it to work.
EDIT:
Well I tried it and it did not work. The phone ignored the fact I had 2 sims inserted and acted like I only had 1.
I flashed the G935FD firmware via ODIN and used a dual sim tray that I purchased on eBay.
I also tried going into the sim menu (it wasn't in the settings menus so had to access it via 'Activities' in Nova) but it would not open, it just kept force closing.
My guess is that it is hard coded into the hardware.

I have s7 930f single sim with stock firmware. Today I discovered option to change sim via hidden menu with activity launcher app. I don't have second card to test if that is work.

..

Now I see the tutorial how to add second sim on s7. Is for s7 dual sim and how get working with 2nd sim the sd card at same time. Those instructions is not for single -> dual sim conversion.

[Discussion]Convert Dual Sim to Single Sim

As plenty of us know, G930F and G930FD have the same structure and they both share the same firmware (yes, the firmware for G930F is also for G930FD). That is also the case with our older brother, the Galaxy S7 Edge G935F/FD.
The Duos variant will remain, well, a dual sim one even when flashing the G930F's firmware.
I just found out what file to modify for the duos variant to convert it to a single sim one. However, I've encountered something that prevents me to continue.
I don't know if this file is also present for the single sim variant and if it can be modified for them to obtain dual sim capability.
So, here, let's start the discussion.
First of all, I have TWRP installed, have dm-veriety triggered, decrypted /data partition, on Custom Rom (Echoe Eom).
If you have a root browser (ie Root Explorer, ES file explorer, etc.) go and browse the /efs partition and open up factory.prop
There is only one line there, the ro.miltisim.simslotcount=2
I tried changing its value to "1" and reboot. Upon reboot my phone will display a sim card mismatch error and that the sim card settings has been changed from dual sim to single sim and needed a factory reset (see photo).
After accepting a factory reset, my phone will just do a normal boot and the factory.prop will revert back to its original value.
I've tried several things, doing a manual factory reset through TWRP after modifying factory.prop (didn't work)
Flashing a stock rom after modifying factory.prop didn't work too.
Flashing a stock rom, flashing TWRP, rooting, enabling system modification, modifying factory.prop, reflashing stock recovery, and doing a factory reset still doesn't work.
So there we go, maybe someone has better ideas, you can freely share it here.

Yeah, Have to ask the same question. If you're not putting a second SIM on the slot, then essentially it's a single SIM phone. Yes you've got the icon to show SIM1/2 but that won't bother you after some time.
I've had the phone for just over 2 weeks and it never had an issue being a Duos. I was initially sad about it but now don't have any regrets. Heck, I now take it as an advantage, I can have a backup SIM in case I had to take one and don't have to bother about taking another phone with me.

Well, apparently the OP is from the Philippines and some people in our country thinks that a dual sim phone is a cheap China knockoff phone and they will do whatever they can do just to convert it into a single sim phone and some social climbers in our country even hate seeing the "Duos" logo on the back and the Sim1/Sim2 logo on SMS and call logs and they keep b*tching about it in forums. I'm not saying that OP is one of those people and I don't like to assume as he may have a different reason than I stated but as for me, I have no problems with it, it is still a premium phone regardless of being a dual sim or not.

Actually I have nothing against dual sim phones. And I had enough time in the community to differentiate a knockoff from a legit one.
As I have mentioned, the single sim variants may have the same file and might be able to convert theirs into a dual sim one, now that's something.
You know, when you spend too much time in the community, when developments seem to slow down, you tend to search for developments yourself. At least, that's the case for me, heck, that's the reason i'm on android after all.

then go to system there open the build.prop
change

into
import /efs/misc/factory.prop and save it !

I Guess you can't convert the Duos Variant to a Single Sim, I'm not really a fan of the Duos Logo on the back So I had to order my S7 online. Couldn't find any Single Sim variant in our country

How to convert Galaxy S7 edge SM-G935F Single SIM to FD Dual SIM???

Dual SIM options appear in menu and phone number of second sim is shown...., but imei is 0000000...0 and call do not work on second sim slot.

XT1572 looking a way to unlock second sim...

I have a XT1572 and dual SIM install, but just the first one is recognize.
Is there a way to operate the second SIM ? Because why they are two SIM slot and just one working ?!
Please help me.

If you have a dual SIM model, just insert a SIM and go... there is nothing special you need to do.

Do you have two IMEI numbers? Dial *#06#, and if you have 2 IMEI numbers it should work, if it only has one IMEI it cannot be activated even if your phone is an XT1572 with dual SIM hardware.

How can you have two simultaneously active SIMs with a single IMEI?!?! That doesn't even make sense...
The point is there are a few threads here about people trying to activate dual SIMs on the XT1572/XT1575 Single SIM models, some of them even have the hardware to do it and some do not, the firmware, radios, and other pieces needed to make dual SIMs work are only available on XT1572 Dual SIM models (India) the XT1570 Chinese version of the X Style. Due to part of the necessary information needed to use dual SIMs being in a protected area of storage. Several people have tried to activate the second SIM on this device when it doesn't have a dual SIM ROM and radio, but it doesn't work, and some models don't even have the hardware.

Hi,
May be my phone buy in Asia different other market, at the beginning it just single sim I just flash stock rom of dual sim (with higher security patch level than in your phone) and automatic active Sim 2.
Or you can unlock bootloader (lost warranty from Motorola) and downgrade OS and flash newest OS Dual sim for your phone
You can see it in attached picture.

SM-G950FD Official ROM

I have just acquired the international factory unlocked Galaxy S8, model number SM-G950FD duel sim, and don't see that specific variant on Sammobile official rom downloads. There are many SM-G950F downloads and correct me if I'm wrong, but I assume they would work, only problem is don't know which region I should use. There are 7 or 8 different regions with the matching PDA and CSC sequences as mine, but does it matter which one I choose? Just want to be sure I have the proper "official" backup rom before I venture into rooting etc.
Have searched this thread and the net to no avail.
Any advice and clarification on this would be greatly appreciated!

G950FD is a variant of G950F. But still I'm not sure if you can flash it or not because modem, bootloader and baseband are exact model number exclusive. Btw Sammobile is not official provider of stock rom. You can try using Samsung's official app.

OK thanks! Now when you say "try using Samsung's official app", do you mean Smartswitch for Windows or Kies 3 or something other?

So sure enough I locked myself out of my phone after rooting (don't ask) only access was download mode, so I tried SmartSwitch and it got me back up and running! So thank you very much for the tip "undercontr"!
Only thing I would suggest is to ensure you have your phone's serial number (required for SmartSwitch) on hand. Because other than acquiring from the dialer code, the only other place is on the sticker on back of phone....it's not on the box. So keep your sticker in a safe place when you remove from back of phone!

If you're not hanging around forbidden stuff in Android, you should always stick to official stuff. Stability is greater in that way.
I wouldn't root my device if it has still warranty.

And thanks to everyone here! - I was coming to ask same question: Would I brick my SM-G955FD by flashing SM-G955F software.. (to enable native WiFi Callling/VoWiFi by fllashing to a region which does not have SM-G955FD specific firmware).

Can you get like a another sim tray and use sd card? I'm presuming its the same as F and no real changes tbh

I just checked my Duo; The SIM Tray has a 'SIM1' slot, and a 'SIM2/MicroSD' slot which looks like it can take either (not both).
