Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

I'm having the same problem, but with G900H. I have stock firmware, rooted and everything's working fine until suddenly, I have no network. I restart the phone and get network again but only for a couple of minutes.

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:
imgur.com/i69HCBM
with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch
(sorry for messed up links but I can't post to outside sites yet)
Hey guys, I come here very often and now I'm going to have to open this thread because I've seen absolutely no posts about my problem..
My S6 Edge+ is currently unable to make any calls and I don't know why..:crying: the strange part is that I can still send text messages and use my SIM's mobile data... Another weird thing is that whenever I reboot the phone, my WiFi passwords are forgotten..
Can any one help me? I'm currently running android 6.0.1 and I am considering downgrading it to 5.0.1 to see if it solves the issue...
Still needing help..
No one?? I really need some help since I've tried 4 different roms and modems ano nothing seems to work....
Have you wiped everything and then flashed a stock rom?

Which variant do you have and which MM firmware did you flash? Check your modem, imei, network operator etc and provide that info here.
Also wifi password IMO related with
Code:
ro.securestorage.support=true
this line in build.prop. I would suggest you to add this line under 'ADDITIONAL_BUILD_PROPERTIES' in build.prop but assume you havent rooted your device. If have, add it.
Powered by Elektrik
I've downgraded to 5.1.1 and it didn't work, I have the international version of the s6 edge plus and now I'm looking for a new ROM to test to see if I can solve it.. I've checked my imei in two different websites and on imei.info it comes clear, but the other site gives me a blacklisted warning, which makes me think since I bought it online second hand... it probably was reported stolen or lost and now it's blocked... which ise rather inconvenient. .
If I go to SIM Card Status it says "Not Available" everywhere, but on imei information it says my imei and on IMEISV the value is 01. It's network unlocked and right now I'm about to flash a new ROM, probably stock..
Hello, I have the same problem at boot after I receive the call when making a call nothing remains of numbering you have a solution? thank you cordially guillaume
Hi guys, I know this is a really old thread but I'm here just to say that the problem was with the IMEI, it was blacklisted..
I changed it with a friend and then everything worked fine..
Thanks for you help mates!

Hi,
I got a Live Demo Unit of a store owner who got insolvent and liquidated his shop. Now I got this device which also recognizes a SIM card. But I can't make any calls and it don't get any cellular access. Also the IMEI is some developer IMEI.
My question is, can I get this unit running? Or can I use the IMEI of my one of my other smartphones? Or is it a hardware limitation? I already flashed latest official Samsung firmware (5.1.1 LP).

try this site .. http://www.naldotech.com/how-to-disable-exit-galaxy-s5-demo-live-unit-retail-mode/
Thanks. I already flashed stock fw. But I still got no IMEI.
stock image wont do anything, i think demo units lock the ability to flash the modem, hence you wont see any radio infos.
There is a thorough guide in the Note 3 threads, and also give these xposed modules a try: Phone ID Changer & Serial Number Changer
Hm. But I flashed a radio. Sim card is also working, but because of a developer imei you can register in cellular network since the imei is not on providers white list.
I will read you linked thread asap. Thanks for the hint.
i just read on that note 3 thread, the OP flashed all the newest stuff, but left the bootloader and modem untouched (what it came with). What model does your demo unit show? On the Note 3, it had a SM-N900X, the X was only for the demo units.

You can flash a modem but you will still have no imei. See the forums on how to flash a modem. You need Odin.

One advice. Don't waste your time. You won't be able to use a sim card with a live demo unit. Even when flashing a modem.
I don't know where I got the modem from. I think somewhere in this forum oder on samfirmware.com
Before I post here I dit a lot of research and I get stuck in this point
The general problem was the imei and the serial number of my galaxy S7 Edge changed to something else after a root and a restore of firmware.I found here thanks to XDA forum the way to fix both of them.Now I have the correct imei,the correct serial number but when I insert a sim card I go on mobile networks and check for available networks and after I choose the correct one it says registered on Network but when I try to make a call or something on the dialer it says Not Registered on Network
I need to knom if there is anything else that needs to be done for the phone read and register the sim card.I still having the error of dm - verity failed so I flashed to bypass that.Beside that the phone is on stock rom with twrp and rooted.Please help me.Thanks for reading

Same thing happened to me a few days ago. To solve the problem I flashed stock firmware, applied root using ODIN, and patch IMEI and certificates using Z3X Box. According to the guy who helped me with the Z3X, there's no way you can make the phone work again without patching IMEI and cert. When fixed, you won't be able to update nor factory reset the phone. If you do so, you'll have the same problem again. It's a matter of KNOX security on the S7 Edge.

Hi Zeth...!
Can you explain why this happens and how to do the job in Z3X ?
I think I need at least version 24.8 (suppport for S7)... can you point where I can get it with no-card loader ? (I was unable to get it).
Thanks...!
Javier.
Well, as far as I know this issue happens because of the new security features on the phone. It has to do with the certificate written on the phone. Once you change it, it triggers an "alert" that is impossible to turn off, unless you patch it again. Unfortunately, according to some flashing sites, it can't be done over Nougat, hence your phone will remain on Marshmallow until a new method is found. I didn't do the flashing with Z3X. I payed a guy to make the process. I've been looking for a card-less Z3X but I only found an older version which doesn't support S7.

Hmm, that looks normal.
However, I noted your software channel is tigco (which from what I can find is Tigo or Colombia Móvil, a Colombian mobile operator?). I'm thus not sure if you can flash the stock firmware we have, as they are mainly targeted towards devices on retail software channels (e.g. retla, retail Latin America).
I'm not sure if flashing tigco/tigo specific firmware may restore your IMEI, if you can get that firmware even.
From echo92's above reply,
I don't think it's Columbian device, because it says LATAM in baseband ?
(If it's different retail in his region, then i don't know.)
May be tigco stands for something else in default language set for device ?
To Questioner,
Make sure you post screenshot in english, it will be more helpful in understanding words..
