When I was using any custom ROMs with CSC of any Other country I was getting error like "Refreshing SIM card data" and the network disappears for some time.
So I thought of doing something to get rid of this error and made a flashable zip of the Indian CSC-DDLA1.
You can flash this zip from CWM RECOVERY Mode.
I have tested this on Custom ROMs but it may also work on Stock ROMs.
To test if the CSC is flashed successfully:
In the Dialer type *#272*your_IMEI_no#
If your Country's CSC is already selected press back button, else select your preferred CSC and your phone will reboot.
And you are DONE!
I am not responsible for any DAMAGE to your Phone.
Press THANKS if you like my WORK.
By default its INU, its Indian right?

Yes, by default its INU/Indian.
You just need to flash it on any custom or stock ROM and you can get INDIAN CSC on any ROM.
Thanks, I have INU right now, so I guess no need to apply this...
Downloading it anyway for future use

Hello,
Just bought a topaz blue unlocked S6. I think it came from an Asian country. The phone arrived perfectly with plastic in box with the same IMEI as phone. However it was rooted with SU. I went into the app and clicked to remove root. It was on 5.0.2. They I tried to flash original firmware with Smart Switch with no success.
I used odin to flash stock 5.1.1 firmware from the UK. The firmware was for 920F. It went all good. I have LTE, SMS and phonecalls. However, sometimes the baseband appears as unknown, but I still can make calls and have LTE. And it still shows the same IMEI as it is on the box and it has always shown it. Is there a way to fix this? Now, I try to flash stock firmware with Smart Switch and it says it can't initialize.
I would REALLY appreciate help. I would love to be able to flash stock firmware from Smart Switch.
I'm in México with Telcel, which uses the same bands as AT&T.
P.S. I really searched and couldn't find anything on my specific situation.
That happened to me when I was still on 5.0.2 and flashed only the 5.1.1 modem. I would suggest downloading the modem.tar file and flash that. Should all be good after that.
I'm currently downloading G920FXXU1AOD4 BTU firmware to flash it with Odin. Might that help me better? My main goal is to be 100% stock without any weirdness. And having Smart Switch recognize my phone!
Well, I'm sad.

You cannot downgrade to 5.0.2 from 5.1.1. Your bootloader will not support. I have the issue with 3G connection. Where to get the Modem.tar?
Need your help!!!!!!
When I buy that phone S6 Dues (G920FD) default was 5.0.2 and I can use 3G without any problem. After that there is one oTA update and my 3G has gone. After that I have decided to use Stock ROM but no improvement on mobile data. I have to select GSM for both the SIM and 2G is there with slow connection. Whenever I select WCDMA/GSM for any one of the SIM, immediatley it shows "Emergency calls only" and no mobile data. Wired problem but is there any solution for that? Same IMEI shows in *#06# and back side of S6. But in IMEI.info and mobile info app shows invalid IMEI. Dont know what is the problem.
Try flashing stock 5.1.1 ROM via odin specific for your country.

OK. My first stock rom was from Sammobile and the issue was the same on that. Now I am using |ROM|★ARCADIA v1.0★|►5.1.1 XXU2BOFJ◄|JULY.25.15|★ and issue has no improvement.
Hello, in december, one day suddenly i was in the car and i was driving through a zone with a low signal, from that moment, my S6, losed the signal, and died (?). Today, are 2 months that i don't have signal. I have also tried different sim cards, but nothing. After i had this problem, i did a factory reset from the phone, i put a different sim card in the phone and it worked, i saw the carrier, and i received the sms with the internet configuration, after 1 minute i lose the signal, after that, again, the phone didn't wanted to receive signal. i also tried with a romanian SIM (i am from Italy), but nothing, i see the R near the signal bars. if i go in settings and i search the network operators, the phone finds all, but i can't connect (the SIMs in another S6 works). my phone originally had a brand ROM (WIND Italy), so first through Odin i re-flashed it, but nothing. i also tried to flash the fw with no-brand, but nothing. I've tried absolutely all, i did reboot, flight mode, factory reset, Odin, changed sim, i don't know what to do. my model it's the SM-G920F, i have the 5.1.1, i never did root or flashed custom ROMs, the IMEI it's okay. if i go in ''SIM card status'', in Signal strength, the signal moves, but in Service state it displays "Out of service". The curious fact is that, before this happens, the phone worked for 6/7 months normal, without network problems, after i started using this operator (WIND), after a few weeks, it started that crazy story. what can i do? :crying::crying:

thanks, should i wait for the italy Marshmallow update or install the other already existing? because here in Italy, Vodafone has released the update, should i install this one, or maybe the UK or another? i am on the no brand fw.
Flash any stock 6.0.1 from Sammobile(it won't change Your knox counter) and if it doesn't work take it to Your carrier seller or samsung service repair center. They both will either fix it for free of give You a new one. Mostly odin reflash fixes all problems.

okay, in past, the flashes i did, i just flashed on Odin without doing factory reset (from system or recovery), or deep clean, should i this time? because updating the fw, it updates the modem part, so i think that i don't have to reset it (?), i don't know, also after i did the update, if the network doesn't works, can i downgrade back to 5.1.1 simply flashing again the fw?
Just make sure you are updating the right rom for your model...dont use another rom for another model...this can get you problems after some times...lets say you flashed vod rom on XEF this will give you ptoblems later mybe loosing imei or signal....and if update ota you get updates for VOD not XEF...its just not right...my advice update right rom for you model look sammobile

i think the problem could be the antennas inside...but i guess the fix is to replace the entire motherboard and that is expensive

i don't know, but it's really strange, because when i updated to MM, i had signal for 1min, but i rebooted it immediatly thinking "if it works, works even after the reboot", but it doesn't. i'm sorry, i hope you will resolve your problem
I bought 2nd SK Telecom unit (930S), which has same SoC as 930F. Is it possible to flash 930F modem to 930S? I get this issues regarding mobile network in LTE doesn't work well, I have to lock it to WCDMA in order to make network run again. I suspect this as modem issues, but is it? Or is this OS problem? Tried 3 carriers, problem persists.
While they are the same SoC, there are some differences that will make flashing G930F over G930S result in bootlooping.
I assume you're not in South Korea?
The firmware will be configuring for Korean carrier / networks. Your best bet would be flashing TWRP, then using this to change your device to your carriers CSC https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957

It could be the stock ROM on there (with sk apps). When I bought mine I immediately flashed TWRP, NAND backup and flashed a custom TW ROM and had zero network issues. I never bothered seeing if the stock ROM was worth using. I'm using BlackPearl with zero problems with network or otherwise on AT&T.
I should clarify many custom ROM's work on goth 930F and 930S, but stock 930F images will bootloop a 930S.
hello, im using g930s too with g930s stock bootloader and baseband/modem. but with hyper alvi 4.1 rom. still got problem in 4G mobile network signal. should i try to change csc or modem file? i think the csc was from wrong country, could that be the culprit? thanks guys
