What I dont have clear yet. If I will still need to unlock booatloader and root my phone or just install this new ROM.
As the only installation steps are:
1. DOWNLOAD YOUR ROM
2. DOWNLOAD THE LATEST PA 4.4 GAPPS PACKAGE from OFFICIAL 0-Day PA-GOOGLE APPS
3. BOOT TO RECOVERY
4. FACTORY RESET
5. WIPE CASHES
I just recently install jelly bean 4.1 with the original firmaware, but I wasn't sure I that was the way I should install the new ROM
