XFA is the south africa CSC. where will you be using the phone? ive used the germany, uk, ireland, romanian and russian firmwares on my A8 here in the states and they all worked just fine. im betting that the phone is locked to its native CSC

i am using the phone in zimbabwe..
so if locked to its original carrier is there any way to fix it or i should take it back to xfa

the A8's are supposed to be unlocked tho. Did you buy it thru a carrier?
go to this address and search for xfa, youll see that its unbranded and should be able to be used on any GSM carrier. You might have to give the carrier the IMEI in order to get it working

May be you are not forced to download and flash a ROM according to your region but just download and flash the CSC according to yours.
It is as useful as you can get the newest version of Android without worrying about the provider (except for the provider like AT&T, T-Mobile and others, please do not take them).

920i - no sim/no registered network after marshmallow update

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)

Please help change firmware - UK vodafone

Please help, I have searched the forum but dont seem to get a solution that works!
I bought an unlocked S6 Duos some years ago and now need to put the official UK vodafone firmware onto it so I can use wifi calling
I have downloaded the firmware and tried to flash with ODIN but always get it failed when doing the image file. I have also tried to change the CSC code using the dialer but get MMI errors (even though it is connected to the network and I can make / receive calls).
I am sure I am doing something obviously wrong but cant figure it out! Any help really appreciated!
here are the details I have from my phone
Model SM-G920f
Active CSC code SIM
Available CSC codes.... lots including VOD (which is the one I think i need)
Bootloader version G920FXXU3DPBG
CSC Version G920FVFG3DPC1
Baseband version G920FXXU3DPB6
I have been trying to load :
Bootloader G920FXXS3DPF5
CSC G920FVFG3DPC1
Many thanks,
CHris
Did you manage to get this to work. I am considering doing the same..does it still remain as a dual sim phone after ?

Unauthorized changes have been detected. Solution?

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

Help finding FW for the Unlocked version (US)

I need help finding the Odin files for the model SM-F916UZKAXAA
For the US variant.
256GB Model
I'm in dire need. I've been fighting Samsung and many others to get something fixed and they all refuse to help. :/
Backstory: Bought secondhand advertised as the AT&T model. After a week stopped working(no calls or texts/data). Just an error message saying "your phone is not registered to a network, you can only make emergency calls"
baseband number in the settings is nothing I can find online. Google shows no results.
Sent to Samsung and they sent an email saying "sorry we cant fix your SM-F916UZKAXAA"
which google says thats the unlocked model not the att model.
which is weird because the boot showed the att logo and had all the att apps preloaded.
Further research shows this behavior is because Android doesnt know how to communicate with the baseband because nothing matches.
IDK what is going on. I Just want to see if trying to odin the supposed model FW will fix my issue.
You can try Samfrew
Here you can download the "U" variant (usually means carrier fw):
https://samfrew.com/model/SM-F916U/
And here you can download "U1" variant (usually means carrier free):
https://samfrew.com/model/SM-F916U1/
If you use regular Odin, it should only let you flash your variant version only (either U or U1)
You can look up patched Odin on XDA if you want to switch it.
