Hi!

I successfully changed CSC from TGY to BRI and vice versa on my SM-N9860/DS.
From N9860ZSU1ATH1 ROM, I just flashed my unit back to the N9860ZSU1ATGM (stock firmware with July security patch) using Odin and then change CSC using the Change CSC app by Mysterious Dev.

Download Links:
N9860ZSU1ATGM or N9860ZSU1ATGM MEGA Download
Change CSC Windows App

Important notes and instructions:
  • Tested only when coming from N9860ZSU1ATH1 TGY/BRI ROM.
  • Factory Reset is required when flashing N9860ZSU1ATGM. If you are new to Odin flashing, check this thread first. Use the CSC_OMC_OZS_*** file instead of the HOME_CSC_OMC_OZS_*** on the CSC slot in Odin. You can use the latter but reset is still required.
  • After flashing is done and and your phone has completely booted, open the Samsung Themes app and login your samsung account, update the app if ask.
  • Before doing the change CSC, do the following first:
    • Enable developer mode on your phone and enable USB debugging
    • Disconnect your phone from internet.
    • Connect your phone to your PC using USB data cable and allow PC connection on your phone once prompted.
  • Turn-off your windows PC anti-virus before installing and opening the Change CSC app (the app is being detected as a virus)
  • If the Change CSC app is not opening properly, you need to run it as administrator.
  • On the Change CSC app, click "Check" > "Connect" > Select "Android 10" > Click "Change CSC". Go to your phone and click "Check out my stuff". Then follow the instructions shown on your windows desktop. Select the 'Android 10' option in the Legal Settings. Select the CSC that you want to test (BRI or TGY) and install. Click "Remove Change CSC" once done.
  • Turn-on you windows anti-virus back.
  • This will not trip knox if followed accordingly.

Do these procedures at your own risk!

    As you may know, I have not yet made any changes to my default CSC (TGY) to the new "CHC" for call recording.

    But while running the following commands (using Google Phone app):

    - SERVICE MODE:
    *#*#27663368378#*#*
    - CSC SELECTION:
    *#*#27262826#*#*
    - BAND SELECTION:
    *#*#2263#*#*

    I Noticed that the CSC Selection shows only TGY and BRI, and Dev/QA.

    Anyone knows what DEV/QA is for? Besides being the obvious "Development and Quality Assurance"?

    Thanks.

    After changing to BRI, I was able to update my phone to N9860ZSU1ATH1 OTA.
    With BRI, I am already getting the 4G Carrier Aggregation on my unit here in the Philippines (which was not happening previously with TGY).
    CA makes a significant difference on my unit. I now have 70-125mbps with it. Without it, it barely hovers 20mbps.
    I have not tested the 5G yet. I have no 5G signal in my place yet.

    I do not understand how people blame Samsung for them importing a phone and using it in an unintended location to the point people are flashing software not intended for said model.... There is a ton of regulation involved in each specific country in regards to mobile services... People expect Samsung to cover each and all regulation across the entire world?... Is there specific knowledge that Samsung disabled the feature?.... When dealing with imported models and flashing different firmware YMMV.... I've imported phones for 10 years and understand that unless I'm buying the Japanese retail version, I will have to deal with anything that comes from importing another regions model... Sorry for the rant :)

    CA was confirmed working out the box for HK in several regions throughout the world... What did you use to test your CA? Could be something that needs to be taken note of as several other members and myself have been running the HK model through it's paces

    Did you try placing the 5g sim in the second sim tray? This is very interesting.....
    And if you are a Hong Kong citizen, then you buy this phone, you come to Europe and you 5g stops... hum hum very good in a 1300€ smartphone [emoji38][emoji38] and xiaomi , oneplus etc why they work around the world? They don't have regulations to cover too?

    Is Samsung bullshitting, but maybe not in purpose , every time they send a update they fix one thing and kill other 2 or 3....
