Hi, guys. A friend of mine asked me to help with sim-unlock of I9500. I no nothing about the background of the phone but it cam with corrupted imei and sim locked status. When inserting the sim, phone poped up notification saying that it works only in US and Latin America.
Initial ROM was I9500UBUEMK1, reflashing it to I9500XXUAMDK with I9500UBUBMG9 modem helped to restore the IMEI. But sim-lock is still present. Tried different modems, nothing works. I get Current Command is 111 when I try to enter service mode. Some modems give access to servicemode menu however, does not read the imei, so unlock is also imposible on them. Any advises are welcome.

Thanks dude, but that doesn't help. Reflashed to stock, still same problem.
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 have N9005 from UK but Iam from Middle East.
Because code for regional unlock doesn't work for me I gave my phone to the phone lab where they just changed my IMEI. After that everything was fine, until I decided to flash another rom (Knox already 0x1,so its doesn't matter).
Because I want new Modem I flashed first last Finland 4.4.2 and after that custom rom and changed cellular operator and sim card.
Now I see "Not registered on network" on Note 3 when on my N7100 this sim works perfect.
In Download Mod I have this info (attached).
What I should do now? I tried to find info about it, but nothing.
Thanks in advance for any help.

To unlock your phone may they flashed Super IMEI now after you change ROM may it replaced with original IMEI or Generic, I think u need to go that shop again to flash Super IMEI, look at below link.

No, Its required SPT Box.
I have downloaded a latest stock Rom from sammobiles and flashed it using Odin.
After flashing everything works fine except Sim card. phone detects the Sim card and shows the signals also. and when I make a call on my number, I can hear the tone like call is receiving at other end but phones does not ring.
My IMEI number has changed to something like this 004451121002 .
I don't have the backup of EFS partition either.
I had same problem on my Galaxy s3 few months back and solved it by flashing patched kernel and patched modem.
not been able to find any patched modem for galaxy s4.
Please help to solve the problem.

Seem like a modem bootloader mismatch.....

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
