[Samsung Galaxy S9+ Guides, News, & Discussion] MeltdownSpectre:
UPDATE (7 APRIL 2022): Samsung has officially declared the Galaxy S9 and S9+ EOL. They will no longer be supported, and FVB4 will most probably be the final build for this device.

Latest stable firmware:

G965FXXUHFVG4 / G965FOXMHFVB4 / G965FXXUHFVB4

---------------------------------------------------------------------------------

How to flash the stock Odin flashable firmware:

1) Download Odin v3.13.1 - Link

2) Extract the firmware file you just downloaded. You should get 5 files:

AP (System & Recovery)

BL (Bootloader)

CP (Modem / Radio)

CSC_OXM (OXM CSC file, will wipe your phone)

HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)

3) Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.

4) Reboot your phone in Download / Odin mode with the following button combo:

POWER + VOLUME DOWN + BIXBY

5) Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.

6) Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.

7) Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

Firmware screenshots, changelog, and download links will be in 2nd post of this thread.

FAQs:

1) Will this trip KNOX, and will I lose my warranty?

Answer: Short answer would be no, your KNOX counter will remain at 0x0 and warranty stays valid as well.

However, some service centers might note regional differences between builds based on the latest build available for your CSC, indicating that the phone has been flashed, so if you're sending your device in for a service/repair/replacement, then I'd suggest flashing to the latest build available for your home country's CSC. Usually not required though, so not a big deal.

---------------------------------------------------------------------------------------------------

2) What if the firmware build number mentioned above is not available for my CSC, can I still flash it?

Answer: Yes, if your current CSC is part of the OXM multi-CSC. You can check that using the Google Doc I made here:

https://drive.google.com/open?id=1IQglKMUCJXfs5UIeSehd1d6s5a6Rh_fC1WuPdycxotY

---------------------------------------------------------------------------------------------------

3) I flashed 'XXXX' build, but now I can't get OTAs for a newer build that's available on my CSC?

Answer: Now, I'll be using fake build numbers in this example, but you should still understand how I'm explaining this.

Suppose your current build is very old, XXU1ARA1, and the latest available multi-CSC OXM build is XXU1BRA1, so you flash it on your device.

Now, BRA1 is not released for your specific CSC, so you won't get OTAs for it to any further builds because no subsequent OTA file exists on the Samsung server for your CSC.

Samsung will then release a new build for your CSC called XXU1BRA2, so the only OTA file existing on the server for your CSC is XXU1ARA1 > XXU1BRA2, so an OTA from XXU1BRA1 > XXU1BRA2 will not be possible, and the only way to regain the ability to get OTAs, is by flashing BRA2 and then accepting further OTAs from there on.

This may seem cumbersome to some people, but if you're impatient and always want the latest build, then just continue flashing as you normally would.

---------------------------------------------------------------------------------------------------

4) Can I flash the ROM in the main post without flashing the builds that came before it?

Answer: Yes you can. When flashing ROMs with Odin, you don't need to be on a specific build to flash them. They don't need to be flashed in order.

You can be on the oldest possible build and flash directly to the latest one.
