There are two possibilities to get the latest firmware:
You are still on the stock OS
- Simply perform an OTA update
You already installed a custom recovery
- Download the latest firmware for your model here
- Extract the
.tarfile - Run the following command:
heimdall flash --KEYSTORAGE keystorage.bin --LDFW ldfw.img --MISC misc.bin --RADIO modem.bin --CP_DEBUG modem_debug.bin --BOOTLOADER sboot.bin --TZAR tzar.img --TZSW tzsw.img --UP_PARAM up_param.bin
Note: The version in the settings screen of both LineageOS and the stock ROM do not reflect the new version number.
Assuming every command worked and neither your computer nor the device shows an error, the firmware update was successful!
