How to make sure I have the latest modem and bootloader installed? - Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco

I am currently running:
Build: ALEXNDR.N960FXXU6FTJ5
Baseband version: N960FXXU6FTJ1
>MAKE SURE YOU HAVE LATEST MODEM AND BOOTLOADER INSTALLED!
Getting ready to flash a new rom, but I haven't done this for a while.
1) How do I check what modem version I have?
Based on the I *think* the modem is "FTJ1", but I'm not 100% sure.
2) How do I find out if there is a newer modem available?
3) What Bootloader version do I have? Is it "6" (the 5th character from the right in the Baseband version)?

Download the latest firmware from samfw.com. Since that website source builds official Samsung servers, the latest firmware there should be always the latest.

Thank you, @Cyndaquissshhh . Just to confirm, it doesn't matter that, in the past, I had flashed an unofficial ROM to my Note 9?

Now where can I find the BL/CP N960FXXS9FVB1 for downloading and then flashing via ODIN.
I found BL and CP here - scroll down a bit.

Yes, no problems. I have done this a few times before.

---

@Cyndaquissshhh what's the trick to downloading the firmware? I click it and it won't download...

---

Oh, there are three buttons (on some pages there will be four). You can either download it from Google Drive or "Download SamFW server". I don't recommend "download on browser" since the downloaded file would get stored as site data. As you can imagine that's not a good thing...

---

I find their site to be very confusing. Thank you for your help, @Cyndaquissshhh . I finally ended up download a file named "Samfw.com_SM-N960F_INS_N960FXXU9FUK1_fac.zip".
Can you (or anyone) verify that I have the correct file?
(Last time I tried something like this I soft-bricked my phone... thanks.)

I don't own a Note 9, but yeah, you have the right files

@notnoelchannel thank you.
Is there a step-by-step showing how to update this file? I believe I can either use Odin or TWRP...?

If there's 4 tars in it, choose what it says. Like if it says AP, then choose the AP in Odin (you'll have to use ODIN ofc)

---

I don't know how it goes for newer devices but I had to always choose only a single file and then flash..

---

@notnoelchannel the .zip file has 5 files that all match up as you said (AP, BL, CP, and CSC) but the 5th file starts off with "HOME_". Does that go in the "USERDATA" box in Odin?

Don't use the HOME_CSC (i guess)
You need only 4 files, try flashing the 4 files but don't put the "HOME_" one

---

But as I said I don't own a Note 9, so I recommend to ask someone else :/

---

But if you choose all the files, it will flash the whole stock rom back!!!so don't!!! only BL and CP as Painkiller-axel said

---

Thank you. I have other questions regarding the flashing process but I think I will start another thread so this one doesn't get too confusing for people to read.
