I'm in stock KK fw.757 and i must root my Z1C but the problem is that the drm keys needs root access to backup it but my Z1 is not root. For root i need to unlock the bootloader but i can't backup the drm keys before unlock the bootloader because my z1c is not root :banghead::banghead:
I know that i can root my phone in locked bootloader but i will loose my data if i follow that method and i dont want to loose my data
Someone can help me?

To get something u have to loose something.. There is no other way available.. You can take backup and restore.. If u dont want to backup restore then u have to stick with unrooted phone
