I Successfully Changed the CSC of My SM-N986B/DS (Exynos)

[*Detection*]

How did you do it man?
I got this error when I tried with your steps.

Device model is SM-N986B

CSC version : N986BOXM1CTL5
Android version : 11
Build date : Tue Dec 22 19:01:00 KST 2020
Country : MALAYSIA
Sales code : XME

Do I have to downgrade?

I am in SouthEast Europe,what CSC do you suggest to use?

Well if you're running 11 and it tells you 11 is not supported then....

Just use the Google dialer trick, install Google dialer, set as default and enter this code

*#*#27262826#*#*

Change to whatever CSC you want, backup first as it will wipe the phone

Think I read someone saying you need to factory reset if it doesn't work after upgrading to 11 then it should work

Long as BL bit is the same you should be able to, not tried

N986BXXU1CTL5 << BL v.1

Hello everyone I have a n986b I used the guide and replaced csc from vgr vodafone greece to itv italy where I live. Samsung pay now works and updates too. 5G no longer works. I downgraded from 11 to 10 and reset csc vgr, 5G is not back. I put back csc itv, reflash latest firmware 11itv but 5G doesn't work. In my area there is 5g, my sim on another 5G mobile phone works. Do you have any solution to fix it? I searched the forum but found nothing.
With activity launcher entering the hidden menu if I block the network on NR the network disappears.
Thanks.

I managed to downgrade to Android10 using the INS July Firmware provided on the first post. I changed CSC with google dialer and now it is SEE/SEE,SEE/XME

Unfortunatelly when I check for software update nothing comes up which means I could be stuck to Android 10 or there is something else I should do?

p.s EDIT: however I changes CSC to BTU (or DBT) and updates resumed so I guess it was something related only to the CSC i had chosen (SEE).

downgrading still works and you can reflash your note via odin with the newest firmware and keeping your csc changed branding

 

[helton.ribeiro]

So...

If i install a DBT version, with the last update .... and change csc to Brazil (ZTO) ...will Samsung pay work normally?

And about updates?

Will check for ZTO or DBT on next time?

Tks

There is no need to downgrade to July to change CSC.

Here is free and easy metod to change active CSC:

Install Google Dialer and dial via it *#*#27262826#*#*, choose desired CSC and press (Install), phone will be reseted.
If there is no CSC that you want, download desired whole firmware via sammobile and flash via ODIN, then again with Google Dialer to change the active CSC.
This metod works on Android 10, not working on Android 11, but if Bootloader is still same (for SM-N986B it is still "1"
Android 11 N986BXXU1CTL5, Android 10: N986BXXU1ATJ1 ) - so it is possible to downgrade to Android 10 and change CSC via Google Dialer, then OTA to Android 11 and all works.
Personally I recommend (and use for all my phones) THL CSC - it have build in Call recorrder, Samsung Pay works and 5G works.
Knox not triggered.
Happy new

Is RCS working for you in Samsung messages? I had to enable it using alliance shield and still it shows only sms when writing message to someone who uses RCS.
Otherwise THL is best csc it has callerID,recording but thankfully it doesn't have the useless places tab in dialer.

I use RCS with Goolge Messages app.I try Samsung Messages on Samsung S21U XXV and Samsung N20U THL - but on both did not able to send RCS or other phones (with Google Messages and RCS) did not see them as RCS capable. So continue to use Google Messages.

THL will stop Samsung Pay on the end of 2021, other thing will work.
Call recording and Samsung Pay - XXV (Vietnam), INS or INU (India)

Im using INS it feels better than THL somehow

For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at H3G (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the H3G will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), try to flash it with Brazil, csc ZTO, it's part of multi pack OWO, then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.

What is the first CSC in Network Provider info in your software settings? You will get OTA updates

Looks good, but in case you want to get btu you would have to factory reset your phone, insert the english simcard in, wait around 10 seconds for the window to pop out and that would reset your phone to BTU customization

So right now what without resetting what updates am I having. I just got everything back .

 

[sivuha0101]

Stick with DBT, you will get the same updates as BTU, the onlly difference is the domain language which you cna obviously change .

Thanks. I'll see when the may update rolls around. I've been using DBT or btu software via Odin for a while. It's kinda long tho so I hope it's fixed now. There's no more 3 bloatware. The only place it says 3 or H3G is in that column of service provider. Know why?

The last CSC is always the original CSC that the phone was sold with. You can only change it by roooting the phone, but it doesn't affect the phone in any way, it's more for samsung repair centre etc.
