Update PRI (.nvu) on Android for 7xxx

I need to perform a firmware update in android, and for that I use the SierraFwDl7xxx tool that comes with the Android RIL package.

I copy the .cwe and the .nvu files into a folder (for example from: Build4399Approved7304CWENVU.zip)
• Generic\SWI9X15C_05.05.58.00_Generic_005.026_000.nvu
• Firmware\SWI9X15C_05.05.58.00.cwe
Into the folder /data/lteimg

I peform the installation with:

SierraFwDl7xxx –v –f –d /data/lteimg/

and it is successful.
After reading the values with:

SierraFwDl7xxx -g

I get

Which means that it did not install the PRI file, only the firmware as I expect the PRI to be 5.26 and it is still 5.2
How can I install/update the PRI file then?

What is the android version? Also RIL?

Also what are the output of at!priid?
