Is it possible to flash a firmware with a different CSC but is from the same region as the original?
I've got a carrier locked S9. I don't mind the device being network locked, the updates are just really slow on my current network. All other carriers from my country have updated their S9 units except ours.
I downloaded an open line firmware of the same region because it receives faster OTAs. I've got Odin and the drivers ready. I'm just wary that flashing a firmware with a different CSC will brick my phone...
For reference, my S9's CSC is GLB and I'm planning to change it to XTC.
Thanks!
Should work as long as the CSC you are changing it from is not included in the CSC you are flashing, otherwise it will just default back to the phones original CSC
You will need to flash CSC and not HOME_CSC in order to change though, which will reset the phone back to factory

Thanks for this! Took the plunge and flashed the firmware... All is good so far.
Now I'll just wait next month to see if I'll still receive OTAs or flashing will be the only way to update

You'll receive OTAs for that new CSC now as long as you don't root or flash anything custom

Hi.
Can you give more details of the process you followed?
Please!.

I have a Note9 (American) and I want to flash the free firmware (for America) with the AT&T CSC (from Mexico's Note9) ...
Is this possible?
Thank you.

Hey there,
Just wanted to confirm one thing regarding changing the CSC, did you phone's Knox get tripped?, are you able to use S Health, S Pay and Secure Folder?
Need to confirm this cause I am planning to change my phones CSC, but I use S Pay a lot. A little skeptic if changing the CSC would trip Knox :fingers-crossed:

I just flashed the TMobile firmware through Odin and it looks identical to the unlocked firmware. The LTE did not change and I'm not getting video calling. Any suggestions?

What is your firmware now? It sounds like it didn't update.

You first need to flash the unlocked firmware (U1), then boot up with your Tmobile sim installed. You'll see something about carrier settings being applied, and then you can go flash the U firmware
Read carefully through the steps from this thread: https://forum.xda-developers.com/galaxy-note-10+/how-to/n975u-n975u1-firmware-links-t3957648
I am seeing the same thing as stu5797.
I purchased a Note 10+ Unlocked (blue, 256Gb), since the Unlocked had better trade-in value on my old phone.
Went to https://forum.xda-developers.com/galaxy-note-10+/how-to/n975u-n975u1-firmware-links-t3957648 for flashing the T-Mo software, so I could get the carrier specific things.
Since I already had the U1 (as it was purchased unlocked), I did not re-flash the U1 package.
I installed my SIM card, booted the phone. Waited for it to say it was rebooting to apply carrier settings. Completed reboot. Shut down. Started in Download mode. Installed the USERDATA_TMB_N975USQU1ASGO_CL16450385_QB24967230_REV00_user_low_ship_MULTI_CERT.tar.md5 from the "U firmware" link. Booted after the install, and proceeded to set up my phone.
After I had done some significant setup, my phone informed me that there was a firmware update ready to go. I let it install, and it upgraded from SGO to SH4. Downloaded Phone Info to compare against Stu, and found everything identical, with the exception of a single character. My product code is SM-N975UZBATMB.
I do not see an option for video calling, no T-Mo boot animation, and no LTE+ indicator. Not sure what else might be missing/different.
I hope this description is helpful in figuring out where Stu and I went wrong. More, I hope there is a fix that doesn't require wiping the phone, as I've probably invested 8+ hours in setup on this one so far.
Thank you for any assistance.
I figured it out and you wont lose any data. Install this in Odin in the CSC spot HOME_CSC_OMC_OYN_N975UOYN1ASH4_CL16618444_QB25286449_REV00_user_low_ship_MULTI_CERT
from the "U firmware."
This wont wipe data and will give you all the Tmobile features like HD calling, 4g LTE, tmobile splash screen etc.
Hope this will help!

Yup, that did it!
Turns out, I had misunderstood the instructions to flash the U firmware alongside the Userdata file. The last time I fiddled with my firmware, it was all one file.
So I downloaded the TMB SH4 firmware, flashed the BL/AP/CP/HOME_CSC, and it looks to be working like a champ. Got the TMB splash on startup, 4G LTE icon, video call showing up in the dialer...
Thanks!

I do not expect that this will cost you OTA support. I started with the SGO U1 software, flashed just the TMB USERDATA (didn't actually get any of the other files in there, because I misunderstood the instructions), and still got an OTA to SH4.
Ford thanks so much for the nice gesture but I could not accept. You are a very generous person. The reason why I can't accept is I am not an expert on this subject and should buy you a coffee. I only flashed that home_csc TMobile file and everything seems perfect but I don't get otas( not a big deal to me)
When you flashed Ford, did you also flash that TMobile userdata file with the TMobile home csc and the other TMobile files? Thanks buddy
This is all still quite confusing. I wish there was an updated thread with a set of instructions on exactly how to change the stock Unlocked phone to a T-Mobile or other carrier model with pictures or even a video with step by step.
I should be getting my backordered Note10+ Unlocked from Sammy in the next few weeks and this is the first thing I am going to do is make it a T-Mobile device will all the apps and boot animations. I'd like to have all my ducts in a row with everything downloaded and instructions in hand so I can hit the ground running on day 1.

It will work the same as the previous models. When you get your device, out your TMO SIM card in and let it provision for TMO.
Download the TMobile firmware. You'll get five files. BL, AP, CP, CSC, HOME_CSC, and USERDATA.
I'm assuming you have ADB, FASTBOOT, and Samsung drivers all set up on your computer.
Use ODIN 3.13.1_3B to flash the new firmware. Just place the files in the appropriate spots. Use CSC and ignore HIME_CSC.
Put your phone in download mode. I believe this year you shut it off, then while holding both volume up and down, insert the USB cable.
Then hit start on ODIN.

I thought about it a little more, and it is possible that we will lose the OTAs. When I flashed the USERDATA, I wasn't properly fully on the TMB SGO. It is possible that the OTA was the one intended for the U1, and that is what I got updated. I will keep an eye out for when TMB releases an OTA after SH4, and see if I get it then.
I would expect it to work properly, given that the hardware is identical, and, at that point, will be entirely on the TMB firmware.
The order I did things in was:
U1 boot with TMB SIM card inserted
Waited for "Reboot to provision carrier data" or something like that (very shortly after booting, did not set anything up)
Waited for reboots to complete
Booted into Download Mode, installed TMB USERDATA (SGO) with Odin
Thought I was properly on TMB firmware because I saw WiFi Calling in my settings, so proceeded to restore from Samsung Cloud backups / copy data with SmartSwitch
Several hours into this, received notification of OTA update to SH4
Allowed update to complete, continued working with phone
Next day, realized I was missing TMB boot animation, noticed this thread
Read through, provided my experiences
Saw your post on the fix
Went back to original flashing post, saw my mistake
Didn't see the SH4 firmware in the "U Firmware" link, so tried to get it another way
Got annoyed with SamMobile, found and downloaded Frija, installed the framework files necessary
Used Frija to download SM-N975U/TMB SH4 firmware
Extracted files from .zip
Flashed BL / AP / CP / HOME_CSC. Did not flash the non-HOME CSC, nor the USERDATA, as either would result in a wipe of the setup I had done so far
Rebooted, got TMB boot animation, waited a while for update (sat at boot animation for maybe a minute, give or take, looked frozen, was not)
Checked the phone, found LTE icon now read "4G LTE", contacts now had Video Calling as an option.
Phone Info now shows "Phone Model" as SM-N975U (pretty sure it was showing as a U1 before)
As far as I can tell, everything thinks I have a N975U/TMB as this point, so I expect things to work as though it were.
Oh, also, the other versions from Phone Info no longer match what you had posted earlier, stu. Attaching the Firmware page screenshot.
Edit:
On further review, the "Available CSC Codes" has also changed.
Was: ACG, AIO, ATT, BST, CCT, CHA, GCF, LRA, SPR, TFN, TMB, TMK, USC, VMU, VZW, XAA, XAG, XAR, XAS
Now: BST, SPR, TMB, VMU, XAS, ATT, CCT, CHA, GCF, USC, VZW, XAA
I flashed to TMobile (flashed all files but userdata) from unlocked, no wipe. When I got into updates I get the following:
I get that as well pcriz. I am assuming to get TMobile otas you have to flash all files including USERDATA. Flashing userdata will erase data so you should use the regular csc when flashing if you want true otas.

Nothing I enjoy more than setting up my phone when I should be sleeping.
I'll give it a try, maybe that will bring back visual voicemail in the dialer

flash this via the patched version of Odin which will allow for flashing of firmware not originally intended for this device(sunce the firmware i linked was unbranded), obtainable here with the phone in download mode. The firmware file youll download will have 2 files that are similar, CSC and HOME_CSC. CSC will factory reset the phone while HOME_CSC wont. If you flash CSC, you will lose every bit of data on the phone. Once that is done, the phone will no longer be branded and wont have any T-Mob stuff on it. It might just work after you flash that, but likely wont as its probably locked to T-Mob. If that is the case, then youll have to buy an unlock code from the netterwebz, which averages about $30
if the Odin stuff is new to you, let me know. Its not hard, its just odd at first.
also, if you flash the unbranded firmware, you can go back to the t-mob version as long as you can download the firmware from somewhere
I'm tired of these ****ty korean bloatware.
I've been trying to flash F firmware on my unrooted N device for a week now with no success, it's always some kind of PIT/Partition error, ticked/unticked Re-partition, ticked/unticked NAND erase, Used/Unused PIT file, patched Odin, unpatched Odin, nothing works, always "Fail Secure (PIT)" error.
someone told me that the F CSC had a different partition than the N CSC, so how do I re-partition? why does it keep failing?
Can an International (F) firmware be flashed into a Korean (N) Device?
why isn't there a clear answer to this question anywhere?
yes i did. actually i took mine to a local mall mobile service shop. the tech guy installed twrp and installed a custom rom- something named lamlazy azmobile bla bla.. . it was all good. the ONLY thing missing was- OTA update. i did lot of youtube and google on this- in some i found the OTA still available in that particular rom while in others that OTA option is missing. that's why i reverted back to the stock KT-variant firmware.
right now i am on the hunt of how to just root and 'hack' the original firmware- just so i can get rid of KT apps which are in control of my only, current gripe- there is no Preferred Network selection option like you see on a global firmware. I only see 3G/LTE Auto and 3G Only options. I need unlocked 2G only, 3g only, 2g/3g auto, 2g/3g/lte auto option.
so, to answer your question- yes it is absolutely possible to convert any korea variant S9+ into global variant. at least with custom rom- not yet sure if it is possible with stock global rom/firmware.

yes you can do it, and no you dont need to bring it to a shop and pay someone. Just get patched Odin and the F variant firmware you want to flash.

already ahead of you, I installed Soldier rom with a F CSC but there some issues that you start to notice after a while because the the partition for the N CSC isn't the same as the F CSC, so the F CSC doesn't install completely.

like I stated in my op, patched odin didn't work for me no matter what I did, and I haven't seen anyone so far that confirms that it actually works in flashing an F firmware on an N device. so did you actually flash a F firmware on an N device yourself?

unpack both the korean firmware's CSC and the F CSC that youre trying to use, remove the pit from the F firmware, replace it with the Korean PIT, repack the file and flash it.
you can also try an older version of Odin, as that has caused so many headaches for folks in the past. Odin version mismatches can be a mother trucker
oh yes, i had the same issue when i tried patched odin. i didn't know much about PIT. so, after fiddling around for some time, i went back to stock KT firmware. by the way, have you seen this?
https://www.youtube.com/watch?v=ycpnsWJdURQ
According to this, we need to root our phone, then remove CSC folder and restart. then copy-paste couple of files in the system folder. He did it on his Note 4 though. But my problem with network selection limitations and bloatwares are exactly the same as he was showing on his KT variant Note 4.
anyway, i will surely try extracting the PIT file fron N firmware and replace that in F firmware. any tips/guide how can i do that please?

What is the pit ?
And has anyone successfully managed to flash a F firmware onto a Korean phone ?
I'm selling a SIM-unlocked Samsung phone that was originally from Verizon. If I flash it back to stock, does it automatically detect what SIM it has and just "adds" those carrier apps? 'Cause it seemed like it did that when I had it on MetroPCS and T-Mobile. Or is that just on jrkruse's ROM? How would I get this back to stock so it can get security patches again?
I have downloaded a firmware file named "SM-G955U_1_20191002135553_sh0v99vvjn_fac," is this the latest?

I dont know what that firmware is. That's not from a legit site it seems. I would use updato or sammobile. For the latest. And yes if you put a multi csc stock firmware it will auto detect sim and personalize accordingly

That's why I'm kind of hesitant to flash it back to stock. But I might have someone interested in it as it is, so I just factory reset it and will wait on a response.
