Can not upgrade Galaxy S9+ /e/OS build : T dev from e-1.15 to e-1.18

Last know firmware for Galaxy S9+ was Android 10, One UI 2.5
After that, Samsung did not release newer versions.

Now “Filter by CSC” for your country to find the detail in the format G965FXXUHF…

in order to check if there was a Baseband version more recent to that installed on your device.

What do u mean under “Baseband” ? I do not see any titel with Baseband info.

Link to my device

Baseband version depends of “CP/MODEM” part of the Samsung Firmware

In the Samsung Firmware name, the three last carracters are for
year / month / release

B is for Fabruary
G is for july

As I can see on the site the last Baseband is CP_G965FXXUHFVB4_CP21749216_CL23733710_QB49528399_REV01_user_low_ship.tar.md5.zip

So, how to correct upgrade from Android 10 to 13 please?

I installed the new firmware with Android 13 from recovery, as usual. I did formatting and factory reset.

Everything works perfectly.
Thank you all very much for your help!

There is no existing firmware based on Android 13 for your device, latest is based on Android 10…
(G965FXXUHFVG4 from 2022 july…)

Only the /e/OS version 1.18-t, your “Custom Operating System” layer is based on the LineageOS version 20, which is based on the Android Open Source Projet version 13 (Tiramisu)
Not the firmware that stay Samsung proprietary, it was based on the Gogol Android version 10 (Quince Tart) and will never be updated…
