I owned a Samsung S3 and rooted it the first couple of days after I got it. Now I'm moving up to the Z2 and I have to say I'm now in a different world. Been reading the guides but I want to be sure of things before I root. I can't go much longer without rooting lol. On Samsung the roms were very carrier specific. Like att, sprint or telus. I'm in Canada and I'm with Bell but see no other sub forums? Is this forum for all Z2? How do I know if my bootloader is locked? I never had to worry before. What is TA partition and DRM keys? Sorry for the noob questions. Just want to get back in the game. Thanks.

Yes, this forum is for all Z2. There are no carrier-specific sub-forums.

Unlocking the bootloader is an intentional act. If your device is new and you have not unlocked the bootloader, then your bootloader is still locked. You might want to also check if your bootloader is unlockable in the 1st place. Go to your dialer and enter *#*#7378423*#*#, then Service info, then Configuration. Under Rooting status, if it's indicated as "Bootloader unlock allowed: Yes", then you can unlock the bootloader if you want. If it's No, then there's no way to unlock your bootloader. You have to wait for a root exploit for locked bootloaders.

Some info on Trim Area (TA) partition: http://www.themobimag.com/backuprest...peria-devices/

Digital Rights Management (DRM) Keys are basically for Sony features such as TrackID. Some info: http://forum.xda-developers.com/show....php?t=2743240

Do search the entire XDA forum if you want more info on TA partition and DRM keys, as the info are scattered across the other Xperia device forums too.

Same with OP, I'm new to this device
All the way since I joined XDA, my device is always samsung series. And always international unlocked version.

Sorry, never meant to hijack a thread. But better rather than I open a new thread

I've try to read and understand first,...
however, I still stuck here and there. Is the step correctly summ up ?

1) backup TA partition.
2) unlock bootloader.
3) restore TA partition.
4) flash CWM.
5) flash custom kernel
6) root
7) then can install custom rom (if I want).

or did I miss any step ?

and flash TA partition the last step to relock bootloader?

Restoring TA relocks your bootloader
Relocking on a custom or modified kernel bricks your device

Step1 do what you need with CWM / custom kernel
Step2 flash stock kernel without any thing
Step3 restore TA
