Samsung G930F (Exynos) with a BTU firmware. I am unable to run any of the USSD codes (even as simple as *#06# for IMEI). I am getting the "Connection problem or invalid MMI code". It is not a carrier issue since my wife's Sony Z3C runs them perfectly being on the same carrier. Any ideas how to solve it? Thank you.
Tried to run codes in safe mode as well with the same result.
I am on T-mo USA.

Yep, read that before I posted. Nothing works from that recipe. Thanks.
Fixed it by reflashing the newest firmware through Odin. Odd...
Try phone info

This happened to me before too, the way I got around it was using the phone info app from the play store, it can run the secret codes and check on other info on your phone. I also got around to reflashing firmware later which allowed me to just type in dialer again.

Hi,
This is my first post but, I'm an avid lurker. I am having some issues with my girlfriends 920i. It received an OTA update to marshmallow and ever since it won't read the Sim card. I've tried to flash the official fw through Odin and still having the same problem. Because it doesn't read my Sim card, I have zero access to any mobile network settings.
I am wondering if when they updated the marshmallow, I lost unlock capability.
Also, her imei and sn still match. Most of the problems I see people have are mismatched numbers, and her phone seems fine.
Any help would be greatly appreciated.
So, I checked the firmware that I flashed and it was INS which seems to be the locked version.
I flashed the INU firmware this morning but still not reading my SIM.
I'm out of options at this point, I'm going to go back to lollipop and see how that goes.
Hi,
I am having this issue for my SM G-920I since 2/3 Jan, 2017. I am using fine on US Tmobile network since Oct 2015, but all of a sudden got the no SIM, emergency calls only and continues to stay like this.. I am curious to know if you resolved the issue and how. Thanks for any feedback!
Help me please
I'm having the same issue. Just flashed INS 6.0.1 firmware on my brand new G920I and now i can't get any mobile signal or data. Tried to flash ZTO firmware for my country, but same issue. My phone was fine before flashing INS firmware. IMEI it's fine too. Recovery shows: Applied multi-csc. What can i do? ((((((((((

Do you also see: " No SIM, Emergency calls only" after rebooting the phone? What's the baseband version ?

Try to connect to Wi-Fi only and once connected, check if there are updates for Software/Firmware.

Already updated and tried to downgrade to 5.1.1, but no sucess. I don't think it's a hw problem, cause it was working before the INS firmware flash, and IMEI number still shows right, no matter what rom i flash (now on MIUI). Can i clean EFS partition and try to flash ZTO firmware again, or i might lost my IMEI and get more problems? Also, wondering if advanced wipe with everything checked on TWRP can help. (data, internal storage, system, sbfs, cache, dalvik cache)
Can you open the phone dialer and enter this code *#*#4636#*#* then clikc Phone Information, and send a screenshot of what you see in the screen (Make sure no IMEI in the screenshot, before you post it here) ? Also check if Radio is OFF or ON.

Codes on my dialer doesn't work, but i'm sure the IMEI is right cause it's showing in phone information. Also, radio is on cause when i search for mobile networks the carriers of my country appears on the screen but when i click on then, just appears a message saying that can't connect
Same problem, any solutions?
I had same issue for over a year, you can check details in my thread, resolved by factory warranty motherboard replacement (free of charge, even thou knox was tripped when I bought it, and I told lady in authorised repair shop that i don`t have warranty).
Forgot to mention that I also tried to repair it via Octoplus box, both by me and some other people (wanted a second opinion), DRK fixed, few new certs written, etc.), not only by flashing fw via Odin or Smart Switch.
And I was 99% sure it was hw, turns I was right.
P.S. country dependable: - in some countries they will probably want to sell you a new motherboard in Samsung (happened to me), but in other factory warranty will be accepted (probably, if the phone is not older than 3 yrs I guess)
Hey guys so after trying the following software (Dr.Fone for Android by Wondershare) to recover some deleted photos off my phone i started getting some message saying: Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes.
Obviously I tried to reboot countless times, tried to do a factory reset and even wipe the Cache Partition without any success. Tried to use Smart Switch too but when going to the Emergency software recovery and Device initialization I get a warning that I need at least 800Mb free. The phone has 16Gb free space . Any solution? Throught about flashing ROM but I don't know if the bootloader is locked by default on Samsung devices and if there's even a official rom.
Thanks in advance
Which model S7?
You can use ODIN 3.12.3 or above to flash a stock ROM from sammobile.com or updato.com
Possible if you check the phone about > status in settings it will say 'Custom', flashing a stock ROM should get you back to 'Official' and remove the error
Regular S7 ( SM-G930F). I'll look into it right now Thanks
Edit : There are so many country ones but there's none for my country. Does it make such a difference? I bought my phone from Germany and use it on a daily basis in Finland. I never heard about a ROM that only works with a specific operator. Besides mine wouldn't even work here.

BTU and XEU are United Kingdom unbranded ROMs, could try one of those
The only things I've heard not working by installing different region ROMs (CSC) is stuff like WiFi Calling / VoLTE etc, haven't heard of anyone not being able to get a signal at all
Check which one you're running now, you're looking at the CSC version
Use this app
https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en_GB
Check under "CSC Code" tab to see what you're running, then match it to the ROM you download

How did you fix it?
Hi all,
I was running a custom ROM for a while (KangVIP) and decided to revert back to stock. I missed it up and I bricked it. so kept trying several methods and finally managed to make it work via dc-unlocker. However initially I wasn't sure which was my original stock rom version. I'm in the middle east so I tried all the different nxt-l29c185xxx versions. nothing worked out, so I tried the second method of dc-unlocker using NXT-AL10 factory firmware and the phone worked. so I debranded the phone using SRKTools, then I flashed different l29c185 stock roms and it seemed that it worked out. However the issue I'm facing now is I'm getting SIM network unlock message when restarting, which shouldn't be the case since the phone originally is unlocked when bought. so I checked through the manufacturer mode and the Bootloader version there shows NXT-C900B120-fastboot
I'm not sure what this means. I tried several ROMs using SRKTools and ItalianKnife and still this didn't change although the build number in the phone changes.
any ideas how to completely revert this back?
appreciate your help
any suggestions..... things I should try??

Hi.
As you said you are on B200 so your phone is marshmallow and it is good because SRKtool just can rebrand Marshmallow version.
My suggestion is to use SRKtools and rebrand your phone to correct brand (NXT-L29C636 or NXT-L29C185)
If you do it correctly, I bet it will work.
Have a nice time.

I've used dc-unlocker to get passed the unlock code. Now I have the phone on L29C185B520; however everything in the phone is working perfectly except the sim; there is totally no signal. I have checked the sim in other phones and it's working fine.
I took the phone to a Huawei repair center and they said its a problem with the mainboard which needed to be changed and it'll cost around $200 USD
I believe it's a problem of modemvm partitions. is there a way to fix it?
Hi everyone,
I bought a phone from a friend, turned out the phone was a Russian version but the was thing is that, it doesn't connect to my local network, sim works fine but whenever I try making a call, it says "not registered on network ". I Googled this issue and finally found a way which I hope will work. And that's flashing it with firmware made specifically for my region, but the model number differs. The phone model number is SM-A750FN while the firmware I found online for my country is SM-A750F. Can I flash it without facing any problem? Or if you any better way to solve the network issue I'd be glad to know.
Thanks in advance.

You don't necessarily need to flash the whole firmware, you could probably just extract the modem.img from the A750F firmware and then convert the modem.img to an Odin flashable .tar file and then flash the file using Odin. All you should need to change is the software that controls your radio.

Yes, IMEI changing will definitely cause an issue, the network will not recognize your device if the IMEI is different than the one that should be there. There is more than one tool or method to fix your IMEI issue, I'm not familiar with those tools or how to use them as I've never had a need to use them.
Try doing a Google search for:
"How to repair IMEI on (your specific model number)".
Thanks
Hi all,
I bought this phone from my friend who was using it on ATT. It is global unlocked phone and I activate and register, change new 5gsim and no problem on Verizon Network.
It is working and fine but, it shows ATT logo when phone is boot up and still it has ATT bloatware.
Under the Software information > Service provider software version is showing below
SAOMC_SM-F711U_OYN_ATT_RR_0016
ATT/ATT/ATT
SO THIS PHONE IS legit!! even Verizon told us. They did everything with me for 3 hours. wow!
Anyway, I think it's the problem of other carrier's software is in
Do you guys know how to change provider software to Verizon? should I contact Samsung??
Please help me.
Thank you!!!!!!!!

@iHeartslutsz https://www.sammobile.com/samsung/galaxy-z-flip-3/firmware/#SM-F711U1
Whenever I flash a new software through Odin after downloading it from Sammobile, the Dark Side RC theme (I think it's related somehow to the so called Star Wars special edition) for samsung, comes as one of two default themes into the system and can not be removed. Hence, even I change the theme from setting, this iron head appears everytime I restart the phone for a few seconds. So I tried different firmwares for my country but nothing changes. So someone from another forum said that my service provider software version differs than theirs. So in short, how to get rid of this silly iron head? Any help would be appreciated.
change csc, use SamKEY (paid) or SamFwFRPTool (free), then flash frimware you need with odin with CSC file (this will wipe your phone and reset to factory), not use home_csc in odin

Thank you. I downloaded totally different firmware files with different CSC code and the problem has solved.
SamFwFRPTool is a tool I use to change my CSC software channel. The way I understand it you need to change the CSC in the program before flashing the u1 software on it so you get a full unlock as opposed to a partial one.
I might be wrong here though so don't take everything I say as being true.
