Unlocking RSA its needed for almost most operations

When you unlock the RSA protection the first part of the main firmware is over-write with other code. After you done with your operations, you will need to restore the main firmware, can be restaured with a rest file (that will restore the first overwritten block) or reflashing the main again.

You need to customize the FS. Its necesary for a working phone after flashing.

This log is after unlock rsa not after flash....What is problem in your phone ?

then
Customize FS Z550i APAC R6CA009
then
Restore Firmware
