Before downloading or installing anything, identify the exact model number and regional variant of your Samsung Galaxy S23 Ultra. A phone sold under the same marketing name can use different hardware, modem bands, partitions, or firmware in different regions. Never flash a package just because its name looks similar. Match the model code, region, chipset, Android base, and build instructions exactly.
LineageOS and other community ROMs are not universal packages. A project release number does not mean that a build exists for every phone. Search the project’s official device list and open the exact device page before downloading. If Samsung Galaxy S23 Ultra or its exact model code is not listed, do not install a build intended for a different device.
LineageOS 24 is associated with Android 17, but support must still be checked per device. Older LineageOS branches based on Android 11, 12, 13, 14, 15, or 16 may remain relevant for devices whose maintainers provide those builds. Do not describe an older branch as the newest version for a phone unless the official device page confirms it.
Read the device-specific installation guide from start to finish. Check bootloader unlock requirements, firmware prerequisites, recovery version, partition layout, required wipe steps, encryption notes, and any vendor-specific instructions. Use only the exact build and recovery intended for the device variant.
Version note: Android 11, Android 12, and Android 13 are older Android releases. Their presence in this guide is historical or relevant to a specific device/build; it does not indicate that Samsung Galaxy S23 Ultra currently runs, qualifies for, or should be downgraded to that version. Check the exact model’s official software history before following version-specific steps.
