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)
Good day
I need your help, I just flashed my Note 3 (SM-N9005) with Lollipop 5.0 from sammobile.com
I used odin to do the flash and it ended up successfully pass. Right now, the phone is running with lollipop but it can't detect any SIM card !!!!??
the build number I flashed is for my country and this is the number
N9005XXUGBOEA_N9005OJVGBOE4_N9005XXUGBOD3_HOME.taror
Any hints or help guys??:crying:
Please any help guys
I'm still stuck with this problem, I tried all kinds of ideas after deep searches but non of them work so far
I even rooted my device and tried three custom ROMs but still my note 3 can't detect the SIM card and the IMEI is nul and baseband version is Unknown
any ideas
The issue is you must have chosen the wrong rom for your region. What Country are you in and is your sim from that country?
YOu need to flash a rom based on your CSC and sim ... I've done this a few times before and it always messed up when flashing custom roms, etc. The only way I found to fix it was to flash back to stock rom for my phones original region (ex: if my phone is from Japan, need to flash Japanese official rom for my mobile provider).
That should restore your IMEI and sim card issues.
If you're not sure, you can post back with details of your phone (CSC - region).
thanks for the reply . I can't really tel the exact location or region of my phone. but whe nI look at the box it all written in Bulgarian language.
I will try to flash N9005XXUGNG1_BGL and see what will happen
Hello to all
I have bought a second hand Samsung galaxy note 3 n9005. i have noticed that the region is mismatched. i am saying this because the signal reception is really bad. call wont go through and after some tries it will and etc. i do not know what is the real region of the mobile. is there anyway to know that? currently i have my imei intact, so i do get signals.
I am currently on KITKAT
i will be really grateful if anyone can help me out.
Hope to hear from you guys soon
Thanks in advance
Original region is not what you want .
You want firmware or baseband and CSC for the network you want to use now .
Phone Info from Play store will give phone details.
thanks for ur reply
Ic
i have tried a few firmwares that work here but their reception is not good
Modem / Base4band is the key .
hmm ic
that is the main issue
how do i identify which baseband (region) was my phone orignally on?
because there are too many of them available and if i try them one by one then it will take too much time and also there is a chance that the imei might go null
Start.
Where are you and what network.
Say you are in the UK and on O2 network then you flash uk o2.
But backup your EFS first .
Sent from my SM-N920C using XDA-Developers mobile app
I have done this but no go
Loose connection bad sim or hardware fault .
dunno
things seems ok apart from this issue and my sim works perfectly on other mobiles
any more suggestions please
Thanks

Go back to stock rom my friend there is no solution for this problem. Every CM based rom has it for few of our devices because of different modem chips.
My cell phone is Samsung SM-G950F but he thinks it's SM-950FD (double sim). Therefore, when I enter my SIM card I have no signal coverage or IMEI. Does anyone know how to correct it? I'll be eternally grateful.
Proof that my cell phone is 950F: https://ibb.co/nuMySo

*I'm sure I installed stock rom G950F and NOT G950FD. So that's not the problem.

Hey,
Which rom did you try to flash and it shows that you have G950FD?
You probably flash a rom, which is it?
Also, go to sim card settings and see if there is DUAL sim settings, if it is not then there is no problem must be the model number only wrong, you can change it through build.prop ( make a backup of build.prop)
In your case i would flash AGAIN stock firmware from Sammobile.com through Odin to make sure there is no other wrong in the rom.
Can someone help me? I have G950FD which Firmware should I flash for my phone? I am using this model in the US
