[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.

Warranty void without unlocking bootloader?

Hi,
My I rooted my z1 without unlocking the bootloader. I thought this wouldnt void warranty, but now, the repair service says my warranty is voided. Is this correct?
@Skanin if u have unroot it or if u have flashed stock firmware which isn't pre rooted before u sent it for reparing, then ur warranty is not voided.

Root and warranty?

Hello,
I'm considering buying a Sony Z3 Compact, and I'm unsure of its warranty status when rooted. I've read that warranty remains in tact if you don't mess with the bootloader.
I just wanted to clarify: if I use this guide, and follow all the 46 steps without skipping anything, will my warranty be void or not?

And do I need to restore something prior to using warranty? They're often quite strict about this stuff in Lithuania...
I have root and botloader locked and my phone has been repaired under warranty without problems

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.

Can it be rooted without unlocking the bootloader?

Can this device be rooted without unlocking the bootloader? I don't want to unlock the bootloader since I want to keep my warranty.
It is useless because regardless of device and brand, any procedure of rooting or going to even partially modify the official system components will void the warranty ... temporarily! You can unlock your boot loader. The question is ifi you can unroot and reblock the bootloader ................ if you can do same it's ok!
You can unroot and relock your bootloader without any trouble.
Off course, personally I only use SU from @Chainfire to root, I can't report about other's methods.
I have unroot and downgrade for reinstall the single variant sim firmware(my 2 p8 is single sim but I use one with 2 sims) , and relock my bootloader for sending it to Huawei for warranty coz of a hardware issue , no trouble.

Yeah you can root with kingroot . but its not good once you root with kingroot you will not able to UNROOT IT. Do it in your own risk . better do by unlocking bootloader and flash thru adb. and supersu (chainfire) is safe and efficient.
