Root Questions - Bootloader / Root

[cronugs]

Hi everyone

I have pre ordered a Z2 and since I am new to android and have always been an avid jailbreaker, would like to root my Z2 and eventually play around with custom ROMS.

DooMLoRD announced today that Touch Recovery is working on the Z2 so it can now be unlocked and rooted. I have a few Q's speciffic to this process.

1. Correct me if I'm wrong but at the moment there is no way to root the Z2 WITHOUT first unlocking it?

2. You need root to do a TA backup, so the current process of unlocking then rooting will result in lost DRM keys?

3. I read that unlocking wipes all data. Does that mean that the Z2 is then unbootable until you have flashed a ROM. Or is the stock ROM still actually in place and bootable, just without any user data?

4. What specific features are lost when you don't have DRM keys? I read something about losing functionality in the photo album and walkman apps, and bravia engine (but that may have related to unlocking the Z!).

Welcome to Android Forums. I think you've had Questions 1-3 answered elsewhere, but just in case....

1. Correct, rooting the Z2 currently requires an unlocked bootloader.
2. Yes
3. User data is wiped, but the /system partition is untouched leaving the firmware itself intact and the handset bootable. Unlocking the bootloader essentially "factory resets" the handet.

4. What specific features are lost when you don't have DRM keys?

Apart from the BE2, you'll lose access to all Sony's media services i.e. any content in Music or Video Unlimited, or PlayStation Network games (including free content offered with the handset and anything purchased previously) will be unavailable.
