[Q] Custom Recovery / Flash ParanoidAndroid on Z2 w/o Unlocking Bootloader topic

Hey folks,

i'm lost on all these Guides on how to root / downgrade my Z2 :confused:

My Z2 got kinda big battery drain since the update to 4.4.4 / 23.0.1.A.3.9...

And since i really like the speed and the features of ParanoidAndroid i would like to have it on my new phone :cyclops:

Is there a way to get PA on my phone without unlocking the bootloader? So that is anything goes wrong with my phone i can bring it to O2-repair?

Hope you can give me some advises :fingers-crossed:
