I installed a rooted rom on my s3 mini and all was good. I then installed a csc changer to check what my csc was, when I seen it was SEB I changed it to BTU because I am in the UK. But when the phone rebooted the csc was "unknown" and the csc changer was showing it blank. My problem now is that I have all my back ups on Kies which now will not see my phone. I have searched, found and tried many solutions to this all to no avail. I tried the original SEB unrooted rom, still csc unknown, I tried various rooted roms and none would let me change the csc no matter what app I used. Any help with this would be greatly appreciated.

try to reflash your ROM with odin as "CSC" not as "PDA" then it should show your right csc code again.

I had this exact same problem when I flashed rooted XXAMA2. All i got was CSC:unknown. Couldn't change it with csc changer.
I had to go back to stock recovery and then flash firmware again with Odin, then I could set right CSC.

make sure you have the correct ROM. Is your device 8190 or 8190N or 8190L? also after flash of ROM and first boot do hard reset.

Have you tried SAMSUNG GALAXY S3 CSC SELECTOR on Play Store, just download/install/run and choose your code, then it works!

Thanks, this is helping.
Has anyone a link to stock recovery? I´m in a hurry, sorry mates... wanted to get my wife´s S§ mini back to working but nothing helped until now.. will give it a try with the stock recovery and reflashing a Sammy ROM. Sammy ROM´s not a problem, but where can I get that recovery only?!

Thanks a LOT, mate!! That´s what I was looking for
Downloaded modem, stock recovery and TWRP now. Unfortunately I couldn´t get the modem back to be shown as it is (after a ROM update modem changed to XXXX ....... since then IMEI was working though, calls were working too but no mobile internet connection) but mobile internet seems to work again now, too... Very curious so far.
Restoring EFS didn´t work but maybe it will work now as CSC is changed back to DBT now or so.. Sometimes flashing Sammy ROMS as PHONE instead of PDA does work (read that in another thread in here).
Thanks again for your help and have a nice evening!
Cheers!
give me some intructions please , what i do exactly (same problem csc unknown ,no mobile data/internet..)

Well the problem is partly solved.. I flashed stock recovery, stock ROM and that modem you can find in tys0n´s signature. Mobile internet is working again but modem still shows XXXX - weird thing ^^
Give it a try in that way. As it seems this is a possibility to get your device working again.
I´ll continue trying and if I find a way to solve it finally I´ll let you know.

Hi guys
Yesterday I was able to flash SentinelROM successfully
I was very happy until when I went out and disconnected from my wifi, I realized that there was no internet connection
Tried to restore APN settings to default, but to no avail
Took out the simcard and put into my iphone, data was fine
So I reflash stock ROM, data worked
Reflash Sentinel, data didn't work
Flashed CM10.1, data also didn't work, although APN settings have been restored to default
Phone and sms worked though..
So now I'm stuck with stock
Could anybody please help?
Just so you know, I'm on O2 UK
Many thanks

I did some reading
The stock firmware which I'm using on my phone has these details (it's Germany - DBT):
PDA: I9305XXBME3
CSC: I9305DBTBMF1
MODEM: I9305XXBME1
which is the same as describe in sammobile.com (the latest)
As I'm in UK and using O2, according to sammobile.com, the details for the latest firmware (O2U):
PDA: I9305XXBMA3
CSC: I9305O2UBMA1
MODEM: I9305XXBLL5
Should I just flash the modem XXBLL5 onto my phone?
Or should I flash I9305XXBMA3_I9305O2UBMA1_O2U.zip stock firmware?
Please advise
Try these
CSC: I9305O2UBMA1
MODEM: I9305XXBLL5

I'll try that and we'll see :good:
I have downloaded the modem file, i.e. XXBLL5.zip, but I can't find that specific CSC file for I9305 although I've done a lot of research..
So I flashed anyway the I9305XXBMA3_I9305O2UBMA1_O2U.zip stock firmware, but no internet at all although with this stock ROM..so I imagine it won't work on Sentinel as well..
I have a similar issue but nothing apart from flashing CM10.1 works
So far tried about 6 different ROMs, all built for i9305 and ALL have no data connection but wifi works faultless. Reflash CM10.1 and I get my data connection back. Which is a pain as I really liked Pandorium with Perseus kernel and JKay framework so I can tweak away
Did a factory reset, wipe cache, wipe dalvik between all flashing. All ROMs install and run perfectly on wifi, just no data connection. Reflash CM10.1 ...... again. And all my problems go away. On T-Mobile/EE/Orange in UK
It appears, after much reading, it could be linked to an incorrect CSC (Country Code). So you might have to flash the CSC code for your specific Country AND mobile carrier
No data connection error is due to the modem is set-up for a different country and mobile carrier, so obviously it can't connect to what it can't find .....
Now I'm just trying to get my head around CSC flashing and tracking down methods that don't NEED a Samsung firmware
CSC is the customer setup configuration .
Network settings for different networks .
See the CSC post .
jje
I just don't understand..why does it work with stock ROM..but not with Sentinel and CM10.1?
I mean..we do not change the CSC and modem after flashing those custom ROMs, do we?
There are lists of modems and CSCs here
http://forum.xda-developers.com/showthread.php?p=26530885#post26530885
I am eager to test them, but I fear those CSCs and modems are for I9300, which would brick my I9305. Please advise

I have done the following:
1. changed CSC to BTU and modem to XXBLL5 - mobile internet worked with stock ROM, but didn't work with Sentinel ROM
2. changed CSC to O2U and modem to XXBLL5 - mobile internet worked with stock ROM, but didn't work with Sentinel ROM
FYI, I'm on O2 UK (pay monthly/post pay),
~ edit APN and/or reset APN to default settings - nothing happened - mobile internet didn't work on both CSC and modem configs
HOWEVER, when I inserted an O2 prepaid/pay as you go sim card,
~ reset APN to default settings - mobile internet worked!!
Reinsert the O2 pay monthly sim, internet won't work ~ reset APN - still didn't want to work..
What more can I do...
I've tried all possible modems...none of them worked..

Yup..
I've tried 3 different AOSP ROMs...the internet just didn't wanna work..
For now I have to settle with stock based ROMs..
I couldn´t get mobile data connection in my i9300 with this rom. I tried a new APN profile with the appropiate settings and information and my mobile data began working. Hope it helps.
Hello guys,
So I have a galaxy note 9 n960f that was rooted with magisk and twrp on android 9.
Today I flashed android 10 Q via Odin.
Everything is perfect except now I have no network.
IMEI information is also correct but still no network.
Any help would be very appreciated.
Thanks

was your phone originally a network locked phone or unlocked phone?

Yes i downloaded files from sammobile for my country.
my phone is n960f and it was rooted with magisk before i flashed the files.
and yes i don't remember exactly but i think my sim was inside when i flashed.
i had this kind of problem before when i had note 4 and i used to flash a patched modem and it worked but i don't know if there are patched modems for note 9.

ah yes.. i remember that too with the note4. but since this is stock its a problem. im not sure but try and flash a multi CSC file like OXM downloaded via frija without the sim and see what would be the outcome. then phone will be on its original CSC im assuming..
Similar issue. Network connectivity was perfect with stock (rooted) N960f/DS running Android 10, though as soon as I flashed havoc, evolution, or crDroid I lost the ability to talk to my network (Verizon in the US), tried flashing my csc which worked fine with rooted android 10, no help, tried manually connecting to Verizon's APN, switching network mode, and manually selected my network, nothing seemed to fix it besides reflashing my android 10 software
Working Android 10 software -
Ap - N960FXXU5ETF5
CP - N960FXXU5ETEC
CSC - N960FOXM5ETEC

yeah usually this happens if you have a rooted phone and you flash something via odin.
unfortunately there no patched modem/ baseband for android 10 on note 9. i got it fixed from a local shop, they had a developer patch the rom manually.
so i am basically stuck with this rom until i can get a patched rom to upgrade.
with the note 4 i had a patched modem file and i had my efs folder backed up so if this happened or my IMEI got corrupted, i would just restore IMEI and flash the modem file via recovery and everything was perfect.
Hi there!
I'm from Brazil, here we use the ZTO CSC, but this file is ARO/ZTO/ZTA. Every time i flash the files on ODIN i got ARO active on the phone, not the ZTO. I have both sims to be brazilian operators (ZTO) but it still gets ARO active.
Somebody have any solutions for this?
Thank you!
Use SamKey

Are you using the CSC_OYM or whatever it is called in the firmware pack instead of the HOME_CSC at time to flash it through Odin?.
Formatting data via stock recovery prior to go to Odin and then flashing the proper firmware including the proper CSC file to clean all the remanent carrier traces may solve it, I think.
Yes

Yes! I did Just that but without success, I think the code way (*#272...) Will work only with personalized csc, multi csc wont work too
**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

Yes sim 2 will work. And after completing flash stock rom for security reasons. Because the above rom is rooted and modified we don't know how secure it is. after network certificates are patched now flash a stock rom from eg sammobile or samfw etc.

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?
I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.
Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
