Hello sir, me again . Time ago a try to change the operator name but from the tweak Y don't work for me (yes a read the pdf and i know that from some user work). So in the page 616 you wrote this line for it:

chown root:root -R /var/lib/csd-csnet && sed -i '1 s/.*/DH/;2 s/.*/DH/g' /var/lib/csd-csnet/42501 && chown csd:csd -R /var/lib/csd-csnet

This is my line where DH is the name and 722310 is my operator number (strange thing i have a 6 number operator when you have 5, im a noob so maby thats nothing :/)

chown root:root -R /var/lib/csd-csnet && sed -i '1 s/.*/ferN9/;2 s/.*/ferN9/g' /var/lib/csd-csnet/722310 && chown csd:csd -R /var/lib/csd-csnet

And here is the oput when i try to change as root, it doesn't say much
