[Q] sim card not recognized after update

Hi,
I flashed the latest (official) firmware for the GT-N7100 from sammobile and now the device doesn't recognise the sim card, so the phone has no network provider...
Does anyone have any idea what can I do to resolve it ?

But isn't it supposed to be the same data ?
Won't PhoneInfo give the same data ?

CSC "Problem" after Nougat update (A5 2017)

hi guys, i first installed the russian Nougat update because in germany (DBT) it wasnt out like 2 weeks ago.
So now it's out and i flashed the original german one over it with wiping everything. So far so good. The problem that i have now is that my orginal CSC "DBT" isn't activated.... it automatically installed the "BTU" CSC (UK)
My question now: How can i change back to DBT? I flashed the german CSC again but i doesn't seem to work that way :/ I added some screenshots from Samsung Phone Info App. The Original CSC-Code line is also blank whyever....
thx in advance!

https://forum.xda-developers.com/showpost.php?p=43553707&postcount=14 if it doesn't work i have another method

the same thing with my phone (i have flashed an XEF )
but this csc is not important at all .....
-You have german language
-the playstore have the same apps
- you have the same samsung fonctions apps and parameters .
-the modem have the same European bands
.....

Yeah i flashed the Portuguese rom and somehow got the sloveanian csc. I tried using the method above for changing but it didnt work. It doesnt matter, its the same stuff anyway.

The other method is to flash a single CSC rom and after flash DBT CSC

Sorry for interuption, but i just want to confirm - you had French firmware and then you flashed Russian and then again went back to French and your original csc has changed during this but your warranty isnt void? Thank you very much.

if you flash non Indian roms , you will lose native VOLTE calling function.

I wouldn't mind using it, I have the Wi-Fi version so what an effect me. But it probably won't work I have the SM-T830.

Any screenshots?

can i use it with SM-T830 model (WIFI only) ?

No

Will I still get OTA updates in the future if I flash this region's firmware and will I lose any data

hey all- any reports on whether something like Swift Installer will work on Pie? it does on my Pie on Note 9 but i know it doesn't on the S10.

Probably not, this should be a multi CSC ROM, so unless he change his CSC manually, he will stay on INS (India) CSC

Indian CSC (INU or INS) is not available in the French firmware. So when we flash CSC, it'll change the default CSC to French. This hap to me when I flashed French Oreo rom on my tab. I had to revert back to Indian rom to get the VOLTE call feature back.
Please excuse me if I'm wrong.

I am not sure if the French ROM is multi CSC, if it is, it should include the INS CSC, I flashed my Note 9 with Indian firmware but it was multi CSC, and my phone still have the MID CSC not changed
I didn't have the time to flash my tab yet, I'll do it soon and report if my CSC changed

Flashed my tab, CSC have been changed to XEF but I am using it without a Sim card, I used the home CSC so my data stayed intact without wipe (for testing because I factory reset it manually to avoid bugs)

If you've upgrade can someone see if you are able to downgrade back to Oreo? I am happy with the Oreo rom and hate when they make it so you can flash a lower build incase the new one is not up to par. Its odd that the French version is up before the Korean international version.

how to Update using ODIN

Hello
i don't know if this question was asked before i tried to search but nothing
i came from xperia xz and flashing was just as easy as downloading the FTF and flashing in flash mod
i bought my S9 that was stuck at 1 Dec 2018 software and no new updates are available (even with smart switch) to download so my best solution is to update it manually using ODIN
i used to have a galaxy gear watch and s5 and flashing was also simple but i came across a thread that said something about CSC Version and i am sacred that i may brick the phone while trying to update it
can someone point me in the right directions ?
my CSC : G960FOXM2CRLI
Service provider SW ver.
SAOMC_SM-G960F_OXM_KSA_PP_0002
KSA/EGY, EGY/XSG
baseband version
G960FXXU2CRLI
build number
PPR1.180610.011.G960FXXU2CRLI
and i live in egypt but the phone was sold is KSA if that's matters
any help please ?
thanks in advance

If there are no updated KSA firmwares for your S9, flash any CSC for the G960F, Germany (DBT ) has the latest June update

If you have KSA sim card need to flash KSA firmware with only Home CSC also and if you have EGY sim card and will come OTA downloads
KSA/KSA,KSA/XSG

Well yes you need CSCs to match for OTA, but it is not necessary for normal usage, once my region releases the latest update I will flash back for OTA

so it's normal to flaash any firmware even if the CSC doesn't match? only the phone model number right? flashing on ODIN like thr normal way kust like the s5? nothing else need to be done ? like enabling/disabling stuff on developper options ? OEM unlock? sorry for my noobies questions

Normal if your own region CSC has not updated their firmware yes, but you will not receive OTA updates until the CSCs match and will have to flash manually each update
There is a big thread about it so I'm not going to go into it in detail here, quick search should find what you need
Nothing else needed, boot to download mode and flash with Odin 3.13.1

Thank you

Recommended Firmware for Unbranding a Samsung Galaxy S20+ (SM-G985F)

Hello community!
I recently bought a Samsung Galaxy S20+ (SM-G985F) which is carrier branded and sim locked. I am looking to remove the carrier branding by using a unbranded firmware. I am trying to find an unbranded firmware that will not affect the functionalities of the phone ( VoLTE, VoWiFi etc..) . Would this be done by finding a firmware with same PDA but different CSC?
Current Branded Firmware:
Version G985FXXU3ATG4 / G985FOWA3ATG4 / G985FXXU3ATG4
Product Code: PGU
Would this firmware work?
Product code LUX
PDA G985FXXU3ATG4
CSC G985FOXM3ATG9
Thanks in advance for your help!

@servenaya
if you have a sim card of Guatemala and you want to keep VoLTE, VoWiFi etc.. for this country
install Version PDA G985FXXU3ATG4-CSC G985FOXM3ATG9
and change your CSC to GTO ( with préconfiguration for TIGO_CGU , PCW_PA and Claro_DR )
LUX have only préconfiguration for Luxemburg ( Proximus , POST , Tango , Telenet , Orange B and LUX )
regards

@yakapa40, thank you! This information is very helpful. I do have a Claro Guatemalan sim and even though the carrier does not support VoLTE, or VoWifi, I would like to keep this features in case they implement them in the future. I did find a firmware with the recommended PDA and CSC (Country South East Europe, Product code: SEE, PDA: G985FXXU3ATG4, CSS: G985FOXM3ATG9). Would this firmware work? From what understand, I would have to first flash this firmware, then change de CSC with Samkey to GTO and lastly, factory restore the phone. Is this correct?
Also, would you recommend using Samkey to perform a carrier unlock before changing the CSC or could I do it later on? I read that Samkey only works for phones that dont ask for unlock code. Mine does ask for a code when I insert another carrier's sim.
Thanks in advance for your help!

@yakapa40 Thank you for your help. You are extremely knowledgeable on this topic! To be honest, I just realize how little I know about flashing even though I've been doing it since 2012. I feel like I understand firmware flashing less than I did before.
I just have a last question. If I flash the firmware with a CSC NEE, and than do the CSC change to GTO, which CSC will be used for future OTA updates? What I mean is, if there is a new NEE firmware will I get it, or will I have to wait for a new GTO update? Sorry, I am little confused with all of this.

G985F OXM is a multi CSC so if you flash the firmware with a CSC NEE , you will get XEF CSC by default
, and when you change to GTO you will get GTO OTA updates

@yakapa40, I was finally able to flash the phone. I followed the steps and got the GTO CSC and the unbranded firmware working! Thank you for helping me throughout the whole process. The only down side was that I still lost the VoLTE and VoWifi options. When I look at the Sim Card Status menu, the IMS registration Status is "not registered". :crying:
