9305 in S. Korea (SK Telecom)

Hello! My 9305(from Hong-Kong) can't register in SK Telecom - emergency only (911 works). I tried to put the sim card to sony xperia(from Russia) - worked fine in 3g mode(umts:3). May the problem be in my csc?
AP: I9305XXBLL5 (Ripper ROM v8) CP: I9305BVBMF1 CSC: I9305TTELALI3

Korean users don't use 9305(

If you cannot ask in the Korean thread then use Google .
Korean users don't use 9305( >>> in that case you are wasting your time .
You will require the correct hardware re networks likewise modem and CSC

Trouble with most firmware on sammobile is that they are multi-csc and distributed for a region together with the factory code (KOR) for Samsung Korea.
If you install firmware via Kies your Product Code remains intact, but installing with Odin, and at reboot, android defaults to KOR inmany cases.
Have you tried going to Recovery Mode and Clear cache and Clear Data ? (recommended after a new install, but may also set your CSC to BTU -but again may not)
The only way to change Product Code to a specific CSC code, is to root your phone and install a CSC changer app from the Play Store.

Is any modem patch for 9305 like Ariza for 9300? May be this will help... I also tried to change option sha256 to 0 in phone lock service menu despite the fact that my phone wasn't locked (worked in many countries) and no result but gps can't find sats now(( returned that option back - no effect...

How to get SM-N920I to detect VoLTE in india without root

Hi fellow XDA members,
I own a Galaxy Note 5 (SM-N920I) which was bought in Singapore under operator Starhub (STH). I happen to use this phone in India and I later realized the phone supports VoLTE but the firmware didn't so I stuck with using the Jio4GVoice app for a long time now and I'm done with it due to lot of bugs and call drops.
I looked online for solutions and found many that involved root or custom recovery to flash the so-called VoLTE fix. I have read articles that said the Indian firmware supports VoLTE so I So, I tried the following:
Download the Indian firmware and flashed via odin. But it fails with error specified file not found. Did a research and i unchecked the Re-partition and again tried and it fails at flashing system . So I re-flashed the STH firmware to get the phone boot up. I learnt that CSC is responsible for getting the region specific network to work.
Extract CSC from Indian firmware and simply flash it on odin. But, as articles say that I'll have 4 files for each boxes to place in odin I only had one tar (<firmware_HOME_tar.md5). Then I read, extracting the modem.bin file and ziping that to a tar file and flash it via odin will help. I tried that but no luck (should I factory reset it?).
Both the firmwares have a single file and articles say that there will be CSC_<firmware>.tar and CSC_HOME_<firmware>.tar.
I don't know where I'm getting wrong. Is this even possible or i'm simply wasting my time? I use samsung pay and S health extensively so I don't wanna trip knox.
Update:
I read that cache.img is CSC from here. So extracted the cache from Indian firmware and flashed that to my phone that has STH firmware. I used the Phone info app and found baseband has been changed and available CSC shows INS but active CSC is STH. Now I guess i just need to activate that CSC. I tried the steps mentioned here but it doesn't work.

here is another method you can try. but this only works if your phone supports it.
For firmware that uses a multi-csc code, you need to select a sales code before attempting to connect to a cellular network. This is especially true for 3G and 4G connections.
There are two ways to select a sales code:
1. Enter *#06# in the phone dialer to obtain the IMEI number for the device. You can then enter *#272*Device IMEI# to select a sales code. If your Samsung device does not return a menu, the product code is not a multi-csc code.
OR
2. Install an CSC changer app, such as the "Phone INFO" app. CSC changer apps do require root access, and they do not work on all phones and all versions of Android.
Hit thanks if it helps !
P.S. IT ONLY WORKS ON STOCK ROM ...! so you need to be on Stock Rom.

Thanks for your help. I tried solution 1 and it Worked
However, before trying out your solution, my device was in this state:
1. Flashed Singapore ROM
2. Extracted every file from Indian rom and repacked the tar except the system.img (as this was failing to flash in odin)
3. After booting I got a notification from SupportAgent telling me that unauthorized changes have been made, tap here to reboot to undo those changes
4. I then read your solution and updated the CSC to INS from STH. And device got factory reset and for the first time I saw VoLTE logo on my phone :victory:
5. I finished the setup and still getting the same error in notification from SupportAgent. So I tapped on it, and device rebooted to a new blue screen with sim card logo on it and then boot up to system.
6. Now, in the quick settings, VoLTE toggle is gone and I got WiFi Calling toggle instead. However I still have the VoLTE icon on the status bar.
7. So later that day, I redo all the steps.
- Flashed Singapore firmware (This time, the CSC Country was Singapore and the active CSC was XTH instead of STH. There was VoLTE toggle)
- Flashed Cache from Indian Firmware (CSC Country changed to India the active CSC was INS automatically. Now got WiFi Calling toggle)
8. I noticed other changes in the software:
- The gallery App doesn't show Grid view so I'm stuck with List view
- The Samsung Pay says, its not supported for this device
What do you think about this?

are you still able to use voLTE ?? after these steps.
about Support agent. Ignore it if you can. or skip it. you do not need this as there aren't any official updates after this. (this is only because now system knows that you have modified it, and it will not receive any update. if you can the disable the Support agent app via settings or if possible via root.)
samsung pay will Not work. as knox should have been tripped to 0x1, so Samsung pay like apps will NEVER work after knox trip.

Note 9 SM-N960F/DS Firmware problem.

I have a Note 9 SM-N960F/DS model. I bought it from KSA (Saudi Arabia). The phone came with Android Pie (9) out of the box.
Unfortunately my friend rooted my phone and now i am running on "N960FXXU3CSFA/N960FOXM3CSFA/N960FXXU3ASF1" version with "Security patch level: 1 June 2019". I am unable to use my Samsung account and all the security features (finger print, Ratina scanner, Face recognition etc).
When i switch back to original firmware i.e
PDA N960FXXU3CSG1
CSC N960FOXM3CSG1
i got all the features functioning but my SIM card shows "Emergency calls only".
Any help will be highly appreciated. Thanks.

Well, My friend took my phone and told me that he will make it compliant with our local network and make it approved from the Telecommunication authority.
He has downgraded the phone with older firmware version i.e N960FXXU3CSFA/N960FOXM3CSFA,N960FXXU3ASF1. The security patch level is 1 June 2019
I have checked the Knox e-fuse which is not tripped which means its an official ROM and not altered.
Now, i have the latest firmware version downloaded i.e N960FXXS3CSG1 but when i try to install it in my phone it does not recognize my SIM card and phone is in "Emergency calls Only" state.

not sure how you check knox but if he really rooted then its too late and knox cannot state cant be reverted.
typically checking via software is not a good method . going to download mode and checking warranty state 0x0 means is not tripped. anything different means it been tripped/blown.
anyways that dosen't make you phone have no signal though.
i suspect he screwed up the twrp recovery flash procedure for twrp and botched the flash back to stock via odin.
read up on odin and how to use it. get latest version.(search and read)
read up so on how to get latest firmware for your phone and which csc your carrier is so that you can download the correct firmware and have best results for your sim carrier.( in doubt try BTU csc firmware)(but search and read about the subject of phone types firmwares and CSC)
also the firmwares your quoted seem old. not sure why you ended up using it but you should get one that is from july.
E.G.:
https://www.sammobile.com/samsung/galaxy-note9/firmware/SM-N960F/BTU/
(get the most recent! july 25th)( u can dl odin from there too)
on your PC, install samsung android drivers or simply install samsung smart switch. it will install the necessary components.
in it self smart switch can flash firmware automatically for your device. so you might want to try it first.
if you go towards the odin flash route and found the correct firmware or want to try BTU multi csc as suggested above:
put phone in download mode and unzip on PC firmware and flash with odin BL,AP,CP and CSC. But for csc choose csc.md5 instead of home_csc.md5
(be patient while AP is being checked before adding cp and csc)
edit: details steps on odin flashing procedure below

I haven't try SmartSwitch for N9 but worth to try as it should be able to detect proper csc for your phone.
Else find the latest firmware for your phone with Frija/Samfirm then flash with odin.

well may be your friend tried to change IMEI of phone which is illegal in any country. Match your IMEI with box by dialing *#06#, if IMEI are same then no need to worry. you need to register your phone IMEI with PTA by paying tax. after paying tax they will whitelist the IMEI of your phone and you will be able to make calls.
just for information, my note 9 is also brought from Saudi Arabia, but at that time one device was free, so i got my phone registered by providing my travel details to PTA and they whitelisted my phone.

Please guide me solution.

Hello, I am trying to switch from an Orange operator rom to a Samsung XEF rom, the problem is that when I flash everything goes normally but the rom does not flash and remains in Orange rom. Yet I have no error message.

For some reason I can't get it to detect my phone after plugging it in. Odd.

Yes. Windows is supposed to automatically install the drivers when you plug in your phone.
You may also install them by installing Smart Switch for PC.

give me custom rom first, then will worry how to flash it

Is there any reason (that we know of) why flashing an AT&T device to the unlocked ROM wouldn't work this year as it has in years past?

Hello, I'm trying to switch from the Orange operator to the Samsung XEF rom ROM, the problem is that when I blink, everything goes normally, but the ROM doesn't blink and stays in the Orange rom. I need to make a mistake.

I have the same problem I have orx and I would like xez, dbt multicsc rom via Odin didn't help either

Problem solved, via Samkey application, S21 5G is already supported

For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at SFR (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the SFR will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.
EDIT. It works with other models as well, usually there is a domain language in each multi csc pack, and for flagship models it's usually DBT or BTU, for cheaper phones it's usually a langauge where the phone sells the most so for some A series models it's either ROM or XEO or XCZ

I am from Brazil and wanted to install my regional stock ROM but everytime I did it, it went back to my carrier's ROM.
What I did in this case was installing an OXM csc (the german DBT) and then trying again with my stock regional ROM (ZTO).
Removed my SIM card and didn't connect to wifi untill I was sure the stock ROM sticked to the phone.
PS: If anyone reading wants a rom from the OXM multipack and is having troubles, try using the Brazilian ZTO stock rom and then go back to yours.

Thanks for that!
I am from Brazil and wanted to install my regional stock ROM but everytime I did it, it went back to my carrier's ROM.

That's true. ZTO is part of a multi csc pack OWO, so it will work for OXM. Good job mate

My S21 Ultra 5G from AT&T is somehow not getting updates and seems to be stuck on ATLF firmware with the December 1, 2020 security patch. Called AT&T...they blamed Samsung and sent me to Samsung. Samsung blamed AT&T and wants me to travel 50 miles away to a Ubreakifix store (official Samsung repair center). Today I called again and AT&T had me factory reset the phone with the result being the same - - no update - software is up to date.
Frija seems to be downloading the newest AUC8 firmware when I put in the model of SM-G998U with ther correct US code which I hope is the AT&T rom.
Is the firmware from Frija safe?

For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at SFR (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the SFR will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.
EDIT. It works with other models as well, usually there is a domain language in each multi csc pack, and for flagship models it's usually DBT or BTU, for cheaper phones it's usually a langauge where the phone sells the most so for some A series models it's either ROM or XEO or XCZ

hi there
I have done this recently, perhaps with a slight fail on my sight, since i updated to the latest OXM pack, since i wanted to switch to DBT from DTM (german telekom) without reading this thread and your post first. So my phone didn't switch from DTM to DBT. until yesterday i had to wait for the updated security patch for OWO pack to switch. So all went fine and i switched from DTM OXM to OWO and back to OXM again.
But basically here starts my problem (if it is a problem, not sure yet):
My phone switched not to DBT, instead it went to EUX, which i guess is the generic code for complete EU countries? i am not sure, since i couldn't find the sales code or CSC for this anywhere tbh. i have two SIM prepaid SIM cards from a third party o2 contractor, so normally (i have done it on my Note 10 plus), like you mentioned, it should ask you to customize your phone and switch to DBT, but for me it simply doesn't ask or go to DBT at all. It simply keeps the EUX. Which i would not have a problem with, when i get regular updates with it like i would on DBT.
If anyone could give me a hint how to change to DBT or what i did wrong, i would appreciate the help. If EUX is fine for getting updates, i am also fine with that, if someone can confirm this. on OWO the software updater said please contact a samsung service center, since i have german SIMs in the phone, but with OXM package and CSC on EUX currently it just says "software is up to date" so it can connect to the update servers if that helps.
A short pm would be appreciated or maybe some help from an experienced user (more than me lol) via telegram as well.
Cheers
Mike

Oy, when I try to run frija, it tells me I need to have Visual c++ 2008 installed?!
EDIT: Finally found the download for it, but Frija doesn't seem to have firmware for the S21+

I was working with someone to find a way to remove Retail Mode from our S21 (SM-G991U1 XAA), and when using Odin to flash, we accidentally used the same firmware BL file for every section of the install. Now the phone is stuck in download mode, and we can't find a firmware download with replacement AP or CP files. Only a single BL .md5 file, or a set of files that don't seem to fix the problem. I found a link here on the forums to what appears to be exactly what we need, but it takes hours to download for some reason, and then fails partway through each time. Always at a different point in the download, too. Sometimes it gets to 2.5GB, other times 3.7GB, but never the whole file. That link is over in this thread:
G991U and G991U1 Firmware Links and Flashing Discussion Here
This was the link I followed:
U1 firmware
Any thoughts? Any help getting pointed in the right direction would be much appreciated. !

thank you so much , what CSC country has Call recording setting ?

Question Changin rom

Hello guys, I just got the ultra, the model is the G998B/DS.
Im from Portugal, and i think i have the german variant. I have two questions.
1- How can i confirm that it is the german one? In the app Phone Info, doesnt say anything in the country part.
2- Since it is not the portuguese one, can i flash the Portuguese rom? (this rom doesnt even say galaxy s21 ultra when turning on. And say "Hallo" when turning on and se you later in german when turning off

First you can check the CSC in About phone - Software information - Service provider software version.
Yes, S21 only mentions Samsung Galaxy in the boot animation.
Mine also came with a branded ROM, but decided it's easier for me to change the CSC with Samkey, than to flash a ROM with another CSC.

How do you do that? with Samkey.
Never heard of it.
Thank you for the reply

Here goes (adapt to needed CSC. Probably OPT in your case):
go to www.samkey.org and download the SamKEY software and Samsung Drivers packages
install both (duh)
go to ebay and search 'SamKEY Credits' - buy whichever you want. You only need 1 credit for a CSC change, but I bought 2 just in case I ballsed it up...
wait for the details to be delivered. The guy I used was in the US, so didn't get my login details until about 3pm UK time. They will send you a username and password to log in to SamKEY
Open SamKEY and log in using your shiny new password
enable USB debugging through the developers menu (tap build number in software 7 times)
remove all lock screen security (pin, pattern, fingerprint and face)
Remove your simcard(s) from your phone and connect the USB cable
type your desired CSC in the 'CSC' box - for the UK the unlocked and open CSC is BTU
click 'change CSC'
Your phone will reboot at the end and will boot up now carrying the new CSC. It shouldn't wipe your user data and won't invalidate warranty or KNOX.
