Root in locked bootloader and warranty - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi, sorry if it was answered before but i don't seem to found it.
I bought a z3 compact d5803 international gsm unlocked, and I'm confused about root, warranty and drm keys.
If I gain root access but keep the bootloader locked (i saw it can be done with some kind of exploit), do i loose warranty and/or do i lose drm keys? My bootloader can be unlocked, but don't want to do that if not necessary.
The current android version is 5.1.1 (compilation version 23.4.A.0.546).
Thanks in advance!

Hi! Anyone can help?
Thanks in advance!

Thanks for your answer. I look at that thread before, but I don't see any reference to warranty, that's why I need to know. If rooting without unlocking bootloader void warranty or not.
Thanks in advance!

Root for Z1 Compact without losing TA

Is there a way to root the Z1 Compact without losing what you do when you unlock the bootloader?

The Compact roll out a week ago, at the moment there is no way to have Root or anything, the developers are working on it so stay tuned on XDA.

Not really true though, http://forum.xda-developers.com/showthread.php?t=2620794
But since there's no older firmware for the Compact you won't be able to backup the TA.
Since that thread was even posted before the launch of the compact, I thought it might be worth asking since alot can happen in a week....

I said there is no root ans still no root yet, that is just Recovery and will be a Root soon for Unlocked Bootlader but at the moment there is nothing for Locked Bootlader.
You have to wait.

Check second post of that thread and then tell me again that there's no root.
EDIT: But for the waiting part you might be right though.

Still no Root for Locked Bootloaders. ..hahah..
Unlocking bootlader
Sorry for being a complete noon when it comes to rooting and bootloader and backups... and what not.
What exactly is at stake here? Just got my Z1 Compact today and learning from my previous devices, N7 and LG G2 (and mistakes) i kind of wanted to unlock the bootloader as soon as possible. Now i am reading all this about TA backup and loosing DRM , and feel both lost and concerned.
Should I bother with the unlock or rather wait until developers has gotten a bit further on this? Planning to use this device as a second phone for rough weather's and hopefully won't fill it up with to much DRM protected stuff (guessing that DRM is mainly for stuff bought through Sony?) so maybe I will be fine doing it later.
Any advice or suggestions are very welcome.
Cheers.

If you Unlock Bootlader you will lost your Warranty and DRM keys and like on Z1 you should lost X-Reality, Bionz Processing and Bravia engine. Losing this features will not compromise the working of your phone but DRM key definetly will compromise the warranty and if you lose them you will cannot Relock Bootloader anymore. Unlock Bootloader is needed if you want flash custom kernels like DooMlord kernel with recovery. So is recommended to Root first your phone and then Backup your TA and DRM keys so in the case you will want go back to Stock or go via Warranty you have just to Flash Stock FTF and then Relock Bootloader. But like I already said, there is no root for locked bootloader at the moment, and this is what OP was asking but he was just challenge me with Root for Unlocked Bootladers.

[Q] Unlocking?

I'm trying to figure out exactly what you lose when you unlock Z3(C).
So far I've discovered that:
- Sony has a webpage that allows you to unlock your device
- Unlocking your device will void your warranty
- Unlocking is the only known way to get root (at least right now)
- Unlocking your device will kill the "TA partition" that contains DRM keys
- Loss of the aforementioned DRM keys will cause some stuff to stop working
I found a huge thread on backing up TA partition for older xperia devices, but no good information RE: what exactly you lose if you wipe out the DRM keys by unlocking.
Do any of you know definitively: what the DRM keys are for and what you lose?
As an aside - it looks like backing up TA partition is only possible before you unlock bootloader and if you've rooted your phone (so probably not possible on Z3C until someone finds a working exploit to get root with a locked bootloader).
Thanks in advance for any insights.
I don't think there is a definitive place which says exactly what you lose by unlocking the boot loader but judging by what people having been saying after unlocking the Z3C and other Xperia phones on 4.4 it seems like the answer is nothing. Nothing is lost on the software side at all.
On the z1c I neglected to back up the TA partition. And apparently lost native mirror cast and some camera features when I rolled the device back to stock.
Back up your TA partition before unlocking BL... If not for the I'm tact features turn for your warranty!

Those that have rushed into unlocking the BL without backing up the TA partition risk voiding warranty I'm afraid.

Problem is, you need root to use those backup tools... So we would need a temp root exploit to backup before unlocking. But from what I've read so far, it doesn't seem like you lose that much, if anything.
I am also curious about this as I need root access but would like to preserve the warranty. Somebody else has also started a thread with what breaks with unlocking: http://forum.xda-developers.com/showthread.php?t=2890936

Most important consideration is your warranty such if your happy to lost it then unlock your BL.

It's not that definitive that you will lose warranty. Sony says it may void your warranty. Known issues with the specific model or batch, or other hardware problems that could not be caused by flashing custom ROMs/kernels will most likely still be covered.

I myself have sent in my Xperia T twice since unlocking the bootloader and on both occassions it was covered by the warranty.
Mind you, I did relock the bootloader and flash a stock FTF before doing that.
Flashtool has a function to relock the bootloader

I don't know if this works on our phone already, maybe someone who has already unlocked would like to try?

i dont really care about the DRM camera problem as i use the camera very little and have no problems with unlocking the bootloader but i cant seem to find info on how to do this with the " Bootloader unlock allowed: No" status .
any help is greatly appreciated.
Z3 Compact Model: D5803
At the moment there is currently no root solution for locked bootloaders unfortunately, a bounty thread has been created here: http://forum.xda-developers.com/z3-compact/general/bounty-root-unlocking-bootloader-method-t2940539
Where did you buy the phone? Is it possible to return for a refund and find a retailer that sells unlockable models?
On the other hand, bloatware can be removed via ADB on unrooted devices. Thread in Z3C android development section
O2 store, oh well happy enough to remove the bloat ware as mentioned above.
Thanks for the swift reply guys really apreciate it.
Stay classy.
I'm not really sure, but maybe you can do that by installing an other stock Romney using flashtool or the pc companion or Emma if you have an operator customized phone, that maybe why it is locked

[Q] Void warrancy and root without BL unlock

Hi to everyone!
I just find that it's possible root our phone without unlocking the bootloader (and lost the dmr key).
What about the warrancy? If I root in this way I'll void it? or what?
Thanks in advance
Once you unlock your BL your warranty is essentially gone.
Because you can't undo the process (unless you backed up your TA partition).

I'm not sure I understand - the OP asked if the warranty will be voided if he roots the phone using the newer method without unlocking the bootloader. Or do you simply re-lock it later with this method and the warranty is still voided?

That's why I said that the warranty will only be voided if you unlock your bootloader. All other things like root etc, you can just revert and Sony will never know it.

Unlocking the bootloader VS phone warranty

XPERIA Z3 Compact D5083
Original Factory ROM
Unrooted
Hello all,
I've been wanting to root my phone since I got it last month. The only trouble is that I'd also like to keep my warranty.
After looking through the phone for a while, I found this in the service menu
"Rooting Status:
Bootloader unlock allowed: yes"
I was wondering if this means I can unlock the bootloader and root the phone while allowing the phone to remain under warranty?
Also, would flashing a recovery mode void the warranty?
Any and all help will be appreciated.

Your warranty will be void if you install custom recovery,that thing in the service menu means that it will allow to unlock the bootloader,some phones have this set to no so they cannot unlock the bootloader in anyway possible,but anyways your warranty will be void if you try unlocking the bootloader.
