[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.

Re-lock bootloader

Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.
Use flashtool
Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?
Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.

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.

Warranty Question for treble support.

i have an Honor 9 Lite LLD-L22A. I want to unlock bootloader and flash AOSP Treble ROM. Will it void my warranty?
Of course. Unlocking bootloader voids the warranty.
Can you relock the bootloader?
"Relock bootloader" what's that about ?
If you have bad rom and relock bootloader - you can pay 15€ to dc-unlocker for bootloader unlocking.
ONLY if "bootloader unlocked" AND "FRP unlock" you can self-repair your phone !
you go to huawei-page for bootloader-unlock-code : your phone is registered as "bootloader opened" !
and relock bootloader nothing help !
all user must self-question "what will i do with my phone ?"
if the answer "i will modify" then you need bootloader unlock AND your warranty is minimized. NOT zero : minimized.
Flash GSI without TWRP
As mentioned in this post https://www.xda-developers.com/flash-generic-system-image-project-treble-device/. Flash GSI without TWRP will it also void warranty??
You still need to unlock the bootloader to flash ANYTHING. So yes, that way also voids the warranty.

Relock the bootloader

Does any one know how to relock the bootloader please on Note 9
Once you unlock the BL on Sammy you trip knox which also kills Samsung pay and other knox apps. Not possible to revert it.
However if you have ticked OEM unlock only and not flashed anything , you can just untick OEM unlock and you are good.
