Bootloader unlock - Xperia Z2 Q&A, Help & Troubleshooting

Hey,
I know there are surely many threads about the bootloader but I never had a Sony so I want to now is: I don't lose any features if I unlock my bootloader right? I know I can backup the Trimm Area so I can get the DRM Keys back if I lose them. In a thread I saw that bootloader unlocking even does not erease the DRM Keys on a Z2, is this right? I just want to know if I lose features by unlocking the bootloader and if I keep the DRM Keys on a Z2.
Thanks

Unlocking your bootloader formats the TA partition where your drm keys are kept
You can backup your TA partition and unlock your bootloader
Restore your TA on a STOCK kernel to un-void your warrenty
Restoring your TA will relock your bootloader hence only restore on a stock kernel
You can install a stock kernel by using flashtool >www.flashtool.net< to flash a FTF> there is a thread at the top of the general section

So if I unlock my z2 bootloader I won't lose any feature like X-reality or break the camera Like Z1?
Thx

Sony Mobile has said no Xperia Service will be lost at all
X-Reality has never worked for me from the day i got this unit but everything else has persisted to continue working

What about OTA Updates? Or App Updates?

First of all, you posted in wrong section.
Second, no there is no way to recover the DRM keys. However there is a way for getting back BE2 after relocking the bootloader.

Plenty of guide for rooting in general section. Two options for rooting w/o unlocking bootloader..

if you root but dont unlock bootloader, can you still have a custom recovery and flash roms?
thanks

Yes, but with more limited options than unlocking bootloader. Now we have working recovery but requires unlocking bootloader. Recovery w/o unlocking bootloader is still in progress, check the original android development section.

thanks; I know I have read that unlocking the bootloader currently disables some features in the phone, but I am sure its only a matter of time till the fantastic devs get that sorted out..plus, once they announce who is carrying this phone in the US, there will be ALOT more people, including devs, jumping on board! :good:
Mine is rooted with vroot and i m not sure will it lost DRM keys or not.

Yes you will have lost the DRM keys, but from 4.4 on we dont need them for xreality (bravia) to work.

Confirmed for Netflix. Warranty is the other consideration. I'd say it's worth doing the downgrade and backing up TA.

i think i didnt lose DRM and Xreality(Bravia) , because i downgrade to 4.3 and xreality works fine...
also before downgrade i successfully backed up TA on 4.4.2 rooted frimware.
What about OTA, will you get a notification when there is an update ?

As stated previously, on 4.4.2 unlocking bootloader doesn't affect xreality, but your ta will now be null so you have lost your drm keys.

You will probably get a notification but updates via OTA or pcc will fail with unlocked bootloader, you'll need to flash ftf's.

Updates don't need ta, only locked bootloader. Your ta will be null as you didn't back it up before unlocking.

[Q] ROOT

Hello, I want to root my XPERIA Z2 but I have never done this before, so I have some questions.
1) If I flash the Recovery used to root, will the stock ROM be affected?
2) After root, will I continue receiving the official updates? If not, how can I update it manually?
3) Can I save the stock ROM to an image for future unroot? How?
4) What do I will lose with root?
To root your Z2 you need to unlock your bootloader and flash a kernel with recovery included of which within you can flash a root zip
Kernel and system are seperate so your rom wont be affected but they do depend on eachother
Root doesent affect anything at all and neither does unlocking your bootloader, you lose nothing at all
You can backup your rom in cwm and restore later, you can also unroot from within the root management app

4.rules kept on device...[emoji6][emoji6][emoji6]

Does rooting screw up DRM keys or whatever like it did on other sony devices in the past?
I am REALLY thinking about this as my next device, and if I can't root without screwing up the device, I'll be put off.

Think of it like this, your drm keys with Z2 are currently uselss, losing your drm keys breaks nothing, (ive tested this)
(in simple words = almost 0 drawbacks of unlocking your bootloader)
What you should be more worried about is your warrenty/garentee , it is voided when you unlock your bootloader

Unlocking or relocking your bootloader resets your device so you cant realy win
And you cant relock on a custom kernel, it has to be totaly stock

I care more about the DRM keys, only because I assumed they added functionality that woudl be lost wtihout them, as they did in previous Sony devices.
Are you saying that, with the Z2, this is not the case and that the DRM keys don't matter at all?

Nope not yet. But I just did some searching it seems that there is no way to root a z2 without unlocking the bootloader. And the ta partition cannot be backedup. Which hence I will lose the warranty. Am I.. right?
For now. Yes. Maybe near future some genius will find the way rooting w/o unlock the bootloader. Wait for it if you don't want lose your warrenty. But it's worth lose it and have fun. Up to you. Think Carefully.

Yes! To root your phone, first, you need to downgrade to rootable firmware which is jb 4.1.2, (there's so many rooting methods that works in that version) then after rooting you can backup ta partition. Search for the procedures and read carefully and follow the instructions, it's all here in xda forum

Hey mate. Z2 can't be downgraded to 4.1.2 as box open firmware is kitkat ...... Aren't you confusing it with Xperia Z or something like that? It is Z2 forum.... not for other. And 4.4 is still rootable no need to downgrade. It just requires you to unlock bootloader.
Sorry! You're right. I just check out. My mistake.
