You could either use TWRP if installed and flash the respective firmware (boot.img) via the install options.

If you are talking about the whole 4.3 gigabyte package, then you should you use Odin. Make sure to put the files where they are supposed to be (e.g. boot.img into AP).

UPDATE (17th January 2020):

January 2020 security patch released for Exynos S9+.

G965FXXS7CTA1 / G965FOXM7CSJ1 / G965FXXS7CTA1

Was expecting them to release it alongside One UI 2.0, but this is probably (and hopefully) the last Android Pie build that the S9+ will get.
[Samsung Galaxy S9+ Guides, News, & Discussion] PRINCE2013:

Battery life for G965FXXS7CTA1 is worse than G965FXXS7CSK4. Anyone have same opinion? Its just my first observation.
[Samsung Galaxy S9+ Guides, News, & Discussion] lulibuli:

Android10 stable is released in Germany

Surprised? I'm too...

Samsung released today the STABLE Android 10 / OneUI 2.0 update in Germany:

More info: Breaking: Samsung Galaxy S9 Android 10 update released!
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
UPDATE (28th January 2020):

Stable Android 10 has been released for the Exynos Galaxy S9+ (SM-G965F).

Rolling out to Germany (DBT) at the moment, but will be available to all regions over the next few weeks. The rest of Europe and the UK will probably be the first to get it right after Germany, followed by Asia and the Middle East.

Build:

G965FXXU7DTAA / G965FOXM7DTAA / G965FXXU7DTA3

The full ROM is available for download on SamFirm / Frija.
[Samsung Galaxy S9+ Guides, News, & Discussion] Firaristt:

60%->15% with 1,5h SoT, but I have to say that on pie I also got bad batterylife (100->15% with 4h SoT). So I will definitely wipe my phone, I'm curious how it will be afterwards.

For pie, mine is very similar to yours. Between 3H30mins to 4H30mins without gaming, long camera use etc. Just browsing, Twitter, youtube(%30 brightness). 3 Synced mail accounts, skype on the background, whatsapp, telegram. Everthing blacked out, auto brightness.

You can't flash and keep your existing set up.

You'll have to clean flash (wipe all data), and start rooting from scratch.

You can use the German version, it'll most likely be the same version that's released for AU.

[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
You've flashed a build that hasn't been released for India, so an OTA file to the next build won't be available on the Indian OTA server and your phone will keep showing 'Up to Date' whenever you check for updates.
[Samsung Galaxy S9+ Guides, News, & Discussion] Invincible29:
My phone was purchased in the UK and since changing the csc which now looks like INS/XEU/XEU this issue has started. Are you saying that I will get automatic updates when the software is released in India rather than UK?
[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
Yes you'll get software updates as they're released in India, not in the UK.

The first out of the 3 CSCs you listed is your active CSC so you'll get OTAs based on that.

Check 1st and 2nd post for details. XSA is part of OXM so it can be flashed.

You can't downgrade, so you can't flash Pie.

The last Pie build was v7, and this new April build is v8. You can't flash anything older than v8 after upgrading.

Okay awesome i only ask because i did update to Security patch 2020-01-01 android Q with flashing but i wasn't huge on it so i flashed back to pie.

Did your devices ever have region locks?

The box would've had a sticker on it saying something like 'SOUTHEAST ASIAN SIM CARD ONLY' or 'MIDDLE EASTERN AND AFRICAN SIM CARD ONLY' or 'EUROPEAN SIM CARD ONLY'.

If so, maybe the devices being region locked are preventing the CSC change.
