I have a Korean G960N device that has a lot of KT carrier bloatware, so I decided to flash a KOO unbranded Korean firmware, however even after flashing is successful the device still shows KT logo, bloatware, and several KT-related options in the 'Settings' app, as well as KTC in the "about device" option. how do I get rid of this ****.

flash the CSC not the HOME_CSC. The CSC file will factory reset it and remove any remnants of the previous carrier info including bootanimation, splash screen etc etc

I know, and I did, and still shows KTC bloat including logo. I saw other people posting about the problem in other samsung device forums but didn't find an explanation. I wish there was a unified forum for these general samsung issues, so that they'll get the largest amount of attention possible.

can you grab a multi csc and flash it without the sim card in it?

lel, I've been trying to flash an international firmware for 6 months now without success, it's always some damn PIT error, tried everything Patched Odin, with PIT file, without PIT file, with NAND erase, without NAND erase, EVERYTHING, and none of it works, and no one on the internet confirmed that flashing an international G960F firmware on a Korean G960N device actually succeeds. just check my post history to see all the posts I made about the issue.

doesnt surprise me that the F firmware worked on a N device at all. Both are Exynos chipsets, so there isnt really a reason for it to not work. 6 months you say? @AthieN have any ideas?

Either the firmware being flashed is mislabeled, or it's not truly flashing. I've seen where Odin says it was successful, but not really... That could be a whole different set of reasons why it's not working though.

My suggestion is re-download the firmware, from a trusted source and try again.

often times the phone is being told what carrier youre on by the sim card, then if the phone has that carriers CSC in its internal database (in the case of multi-CSC firmware sets) the phone will recognize the carrier and then install the carrier specific crap. I use the U1 firmware and dont have any of the carrier junk that it originally came with. I got it on a Cricket offer and very quickly got rid of all the Cricket junk by flashing the U1 firmware

I successfully changed CSC to KOO on my G960N after it was SKT to do that i had to
- root the device
- install phone info app
- use the tool to change csc
You will have a choice of 4 CSCs choose KOO and install
PS : backup data as it will be erased

Thanks again for this help bro , i already forgot about the csc code changing , only thing who were annoying to me were the SKC blootware and bootanimation
i succefully uninstalled the blootware after rooting and using root uninstaller pro , then about the bootanimation i couldn't find any way to change (even by changing files into system/media/ ) , so i just left it
but good thing you gave us the steps , maybe it will help one guy who is willing to change his CSC code

Hello everyone. So I have a S20 Ultra SM-G988N. Its a Korean variant with a Snapdragon Chipset. It has the option OEM unlock and all so the device is rooted. I also was able to change my CSC without doing a data wipe...

What I did was go into the root of the phone into /ets/imei/mps_code.dat. I opened that file with text editor. For me it came up empty so I added the text "KOO" with a different text editor because the one provided by my Root Explorer wasn't letting me edit it. Once I added that in I restarted my phone. My phone started up, had the regular Samsung Logo. But if course some of the blostware is there.

My big issue is the phone connects to Korean things as in some apps will say my Region is Korean. For example my Weather widget (Samsung App) would only let me pick location by state, or country. I can't choose the town I live in nor does the app knows my correct location. It would say I'm in Bethpage Korea.

So my question is because the SM-G988N has a Snapdragon Chipset, would I be able to Flash an U1 Variant Home CSC Using Odin? This way I have multiple CSCs which I can then use to debloat and get the phone to be like US Version.
