how can find to do that ?
Edit : i just found a generated roomservice.xml
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="device/samsung/gts4lv" remote="github" name="LineageOS/android_device_samsung_gts4lv" />
<project path="device/samsung/gts4lv-common" remote="github" name="LineageOS/android_device_samsung_gts4lv-common" />
<project path="device/samsung/qcom-common" remote="github" name="LineageOS/android_device_samsung_qcom-common" />
<project path="kernel/samsung/sdm670" remote="github" name="LineageOS/android_kernel_samsung_sdm670" />
<project path="hardware/samsung" remote="github" name="LineageOS/android_hardware_samsung" />
</manifest>
so i have added the last line from your exemple, and saved it as gts4lv.xml roomservice_xml
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="device/samsung/gts4lv" remote="github" name="LineageOS/android_device_samsung_gts4lv" />
<project path="device/samsung/gts4lv-common" remote="github" name="LineageOS/android_device_samsung_gts4lv-common" />
<project path="device/samsung/qcom-common" remote="github" name="LineageOS/android_device_samsung_qcom-common" />
<project path="kernel/samsung/sdm670" remote="github" name="LineageOS/android_kernel_samsung_sdm670" />
<project path="hardware/samsung" remote="github" name="LineageOS/android_hardware_samsung" />
<project name="TheMuppets/proprietary_vendor_samsung" path="vendor/samsung" remote="github" depth="1" />
</manifest>
