Hi guys,

This is not gonna be much info but to let you know it is possible, at a cost.

So I bought an F936N - CSC: KTC (Korean). It came with the KT branding and the nasty bloatware with the extra setting menu for KT.
I was sick of it. I tried Samkey, I tried Samfw frp tool. Nothing worked.

I personally don't care about tripping knox, I don't use Samsung pay, password, or the file vault stuff. I just use google pay (Wallet now)

So I followed this guide:

Change CSC on Samsung Devices (Root)​

  1. Install X-plore File Manager app or any other root browser from the Play Store. [googleplay url=”https://play.google.com/store/apps/details?id=com.lonelycatgames.Xplore”]
  2. Launch the app, go to Root Explorer option and change R/O to R/W.
  3. Navigate to /efs/imei/ folder, edit the CSC code in the mps_code.dat file and save the changes.
  4. Then go to /system/csc/ folder and edit your CSC in the sales_code.dat file. (System/CSC did not exist on my phone. but I did find the file sales_code.dat file within other folders that were named as the CSC such as KTC, SKT, KOO. I deleted all the folders except for KOO.
  5. I just rebooted into download mode and flashed KOO firmware and it worked! No more KT carrier branding crap!
I've yet to try OTA. Not sure if it is no longer working or it is working. I'll wait for an update and see if it picks it up or not.

Update: OTA works

Not sure if we can replace the files from a different vairant such as F936B and flash its firmware... Would that give us the ability to change the phone completely?? Definitely something I am willing to tinker with on my phone but I would need someone to send me the files with an F936B and that person must have their phone rooted.

Cheers!
