Thank you for the answer.

Another noob question can I still unbrand the phone and use all the sony features?

Yes you can - for that you need this files:
MAIN: W580_R8BE001_MAIN_GENERIC_LA_RED52
FS: W580_R8BE001_FS_AMERICA_2_RED52 and
CUSTPACK: HB1-06_Gen_CDA102568_107_R8A_GENERIC_AMERICA_2

This is generic SE firmware
