You have to choose the correct ROM first. So if your phone is SM-A505F you need that ROM. Not recommended to use other ROMs like SM-A505 FN, G etc.
Once you have the correct ROM (must be newer than your current) use Odin 3.13 or newer to flash your phone . before flashing do back up and then remove all accounts!!! Then remove your SIM and memocard and do hard reset. Connect to Odin in download mode and flash. Wait till its completely finished and boot up your phone. 1st boot can take up to 10 minutes, once you see the Start screen insert the SIM card from desired region and let the phone restart again.
My phone for some reason picked up CAC product code (Uzbekistan). Flashed latest ROM inserted my Vodafone SIM and after restart my phone was on BTU (UK unbranded).

is flashing different CSC ROM will trip Knox

I my case this method for FN version did not worked any different way to do it?

No it wont trip knox as long as you are flashing official samsung firmware.

OK I investigate a bit today
looks like I was able to change CSC from ROM to FTM (Freanch Orange) using brand Orange from Poland (OPV) - all was done with JUN patch the same patch level files
I would like to change from ROM to XEO (Poland unbranded) and for this I did not found any way to work

I think that it's somehow let you change the CSC only one time... I recalling that I was able to do it on my A50 and A70 but only one time...

in my case it is more like I can change to branded CSC like orange or T-Mobile ( did this few time) but it not give me Poland as a country
I cannot change to unbranded CSC like XEO - it always show ROM as active CSC (softwanre CSC it is showing XEO) but for example news I have from Romania

typically it will remain as whatever sim you have in the phone.. there are tricks u can do.. id search some more as theres many csc related threads.. also make sure that csc u want is actually included on the device already since if it doesnt exist then well you cant use it until u get the right csc..

You didn't say what region you want. In my case I was after UK (BTU) or Germany (DBT).
Do hard reset (sim and memory card remove). Turn on phone without sim and wait until it says No sim inserted. Insert the sim from region or country you want to have on your phone.
Make sure you have multi CSC ROM. In my case it was ok. Changed from CAC to BTU.

There's no LTE/4G only mode. So if this is what you want no need for flashing different ROM.

You need multi CSC ROM. First time boot up without sim and memory card. When boot finished will tell you insert sim. I think Samsung set up phones to allow ONLY one change and only first time...

Hey mate! Just flash newest firmware of India via ODIN
Or use Samsung Smart Switch for computer to get faster updates :good:

Is it safe to flash A505F firmware on the A505FN device? As far as I know, the only difference is NFC.
And is it possible to void the warranty by doing this?
I tried Smart Switch a few times, but no updates.

Hi thanks for your reply.
Should I need to remove all accounts, and make a factory reset first?

Smart Switch only will provide you the newest firmware in the same line, not an option to use other different firmware from a different region.
Ever is recommended to do a factory reset/format data before to "switch" to other firmware and make a backup before to restore it in just minutes with SS.
Install Phone Info(Samsung) and there you will find the CSC availables for your device before to change the firmware (most of the international models are multi_CSC compatible), search for the regions and compare them here https://www.****************/2017/0...specific-product-code-csc-and-country-region/ if some of them is convenient for you then you can flash it, check before your bootloader version, I think all are now in v1 but check it before to go further.

Yes, you usually can (I switched a lot of times) but you could find some issues regarding to radio/baseband depending on how different they´re.
Take a backup before using Smart Switch, take note of your actual firmware in a safe place if something goes wrong and don´t forget to enable USB debugging and OEM unlock before to go.

Hi,
Good yes already did a backup and OEM Unlock and USB Debugging are one.
I'm simply waiting the firmware to be downloaded. Take very long time to download from samfrew

Finally succeeded in flashing to INS.
I forgotten to remove my Sim Card but even that it has changed the CSC.
Thanks a lot for your help @SubwayChamp

Hey, what's the model of your device? Is it FN, or F? Because Indian firmware is A505F, so I don't know if I can flash A505F firmware on my FN device.

My model is A505F. I don't think you may install F on FN. It may work but you may have several problem with correct functionality of the phone or even brick it.

F firmware on an FN device should be ok afaik, but I believe you'll loose NFC
Also keep in mind that INS csc has this string in cscfeature_network.xml
<CscFeature_Message_ConfigImeiTracker>+919560345888,+918424098931,+919176905802</CscFeature_Message_ConfigImeiTracker>
I remember that this was a problem on custom roms for the old A-series since all roms for some reason added INS csc, so a bunch of users in europe got charged extra for messages to india if they didn't remove that from cscfeatures..
Not sure if it still acts the same, but I can confirm that the string is there in INS csc for A50.

Thank you.
There is finally firmware with July patch for FN versions of this device, so probably I'll wait few days, because only 5 countries in Europe got an update to the newest version, skipping June security patch, but I hope we'll have new features in the camera.

my apologies for the tardiness of this reply, i was away on vacation with my family. Here is the most recent FW for your device https://www.sammobile.com/samsung/galaxy-s9/firmware/SM-G960F/DBT/download/G960FXXUAETG3/351513/
i strongly recommend downloading your FW via samfirm or frija (im a frija guy myself) as they download about 7x faster than directly from sammobile. Any time youre attempting to flash fresh FW and issues arise, the answer is always going to be first to download a fresh copy, then check the cable or try a different one, then the computer. If all else fails, try a different computer. Odin is tiny and both the FW and Odin itself can be put on a flash drive allowing this to be attempted on another computer quite easily. FWIW, i have a fat AF cable from Anker and it charges like none other, but you cant Odin flash with it. Go figure, right? Anyways, i hope this helps and if youre still having issues, please let us know! Have a good one!

Noob question: Can Odin change my German branded SM-G988B/DS to Nordic firmware?

Hello,
I am completely new to changing firmware using Odin, and I want to make sure, that I don't brick my phone
I have bought a S20 Ultra 512GB 5GB DS (Exynos), but it seems to be a German firmware, as it comes with Deutche Telekom apps preinstalled, two of which can't be uninstalled, and Samsung Members speak German instead of Danish.
My biggest issue, though, is that the latest OTA security update is May 1st.
Base band version: G988BXXU2ATE3
SAOMC_SM-G988B_OXM_DTM_QQ_0006
I found this: (can't post links on XDA yet):
samfw -> firmware- > SM-G988B -> NEE -> G988BXXU2ATF5
Which is for the scandinavian countries. (Nordic)
Changelist 18862671
Build date Mon, 08 Jun 2020 06:59:35 +0000
Security Patch Level 2020-06-01
Product code NEE
PDA G988BXXU2ATF5
CSC G988BOXM2ATF5
The questions:
Can I apply that to my phone, or will it brick the phone?
Will it get regular OTA updates for the nordic variant afterwards?
How much user data will be retained after firmware update?
Thank you so much for your assistance to a complete newbie

If you want to change it you will need to use Samkey (paid).

Oh, okay
That's another new thing for me to get into...
I will read up on it and get back with more questions
But can I ask already:
Which of these procedures (samkey and Odin), if any, will break warranty?

Hi again,
Sorry to be of bother...
I succesfully switched the CSC of the OXM firmware from DTM to NEE.
Now Service Provider Software Version is: SAOMC_SM-G988B_OXM_NEE_QQ0009
NEE/NEE,NEE/EUX/DTM
I know for sure, that the NEE models (though 128GB version) has received the One UI 3/Android 11 update.
But it is not offered as an OTA update to me.
I have rebooted twice, but still no OTA update.
I'm still stuck at an update from September/October.
Is it because mine is a 512GB version of S20 Ultra, while the rest of the NEE versions are 128GB?
Or is it because it still reads DTM at the end of ...NEE/EUX/DTM?

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:
