Firmware flashing and warranty/functionality - Sony Xperia XZ Premium Questions & Answers

Hi,
Can I check with you guys
1) As of 7/6/17 there is no way to flash alternative stock firmware onto the XZ?
2) Would flashing alternative stock firmware void the warranty?
3) Would flashing alternative stock firmware result in a loss of functionality e.g. in the camera (like root would)
My own read of the threads is 1) No 2) Shouldn't 3) Not sure

Doesn't seem to be anything out yet.
Flashing something else than stock doesn't void warranty.
Only unlocking bootloader kills the DRM keys so no, it wouldn't.

Does flashing to KG5 with odin void warranty?

So, does it?
Also what's the difference between KG5 and KG7.
I live in the Netherlends (EU) so can I flash to either one?\
And would there be a way to go back to my current rom?
Thanks in advance.
Flashing another ROM from the original will void your warranty but you can go back to original and un root in most devices

[Q] Keep root and recovery with locked bootloader after upgrading to Lollipop?

Hi guys,
My girlfriend has a Xperia Z3, currently not rooted, bootloader is locked, no custom recovery and running Kitkat. I'm planning on rooting her phone for her install TWRP just to make a backup of the ROM, then I will update it to Lollipop right after.
I want to keep the bootloader locked because from what I've read, unlocking bootloader wipes the DRM keys or something, which apparently affects camera and even battery life for some people. I know I can back up the TA partition but that doesn't fix the fact that the camera will be affected somehow. I just don't want to take the risk and deal with the possibility.
So how would I root and install TWRP on a locked bootloader Xperia Z3 running Lollipop? I haven't seen any topics or guides on this, most are for phones with UNLOCKED bootloader so it's not really helping...
Read the Guide in the general section for rooting a locked bootloader

You haven't researched much i see..
If you have 23.0.A.2.93 version, all you need is to Root, install TWRP, then FLASH a pre-rooted Lollipop rom.
I've read that guide already and I don't see any pre-rooted LP roms for either New Zealand or Taiwan. I know it probably won't matter, but for phones like Samsung Galaxy S5, we have CSC codes which basically gives you access to certain apps or options depending on the country of the ROM. If possible, I'd like to update to Lollipop from the official OTA and then root it from there.
Also, I'm on a newer KK firmware, which means I'll need to downgrade in order to get root. But doing that also means I lose all the contents on the phone, which I want to backup first using Titanium Backup. I understand there's a sacrifice here but I'm a bit confused as to why we couldn't just flash recovery using fastboot (like most other phones do) and then install SuperSU from TWRP? Or is the downgrade necessarily in order for us to achieve root via an unpatched exploit?
UPDATE:
Forgot to mention one major issue, my girlfriend's Z3 is D6653. The 23.0.A.2.93 firmware for D6653 is for T-MOBILE, but my girlfriend's phone is an international variant so I'm not sure it's compatible.
you know you can flash a rom with flashtool and not have it wipe the data?

Help! Sony Xperia Z3 Dual (D6633) pre-rooted

Hi all
I have searched for a long time about rooting my device, but i found nothing
I have Sony Xperia Z3 Dual (D6633) with android 5.1.1 build 23.4.A.1.232 and locked bootloader.
So, I need to root it or install a pre-rooted stock firmware without touching the bootloader.
Hi, you need to flash a kitkat rom with flashtool then root with giefroot. (I'm not sure about other rooting methods but this is the safest way IMO.)
After it got rooted, install a recovery so you can flash pre-rooted stock firmware or whatever you want. Remember to backup TA partition.
I had D6633 before and worked perfectly.
I have posted this before but you can go directly to the thread http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056

As far as I know, stock roms with stock kernel don't need bootloader to be unlocked. You need to unlock the bootloader in order to flash custom kernel and aosp stuffs.
tl;dr, if you are not gonna use custom kernel and aosp stuffs your bootloader can remain locked.
Ok, if you want to install moonbreakers, here's what I did when I first bought the device. I never unlock my bootloader.
1. Prepare the tools and root the device using Giefroot. and I recommend you to backup TA partition first just in case.
2.Install dual recovery.
3.Now that you have a working recovery you can flash any stock roms.
here's the guide by G-FACE.
if you want to unlock the bootloader remember to backup TA partition before you do it. If it's lost you can't get it back.

First of all, thanks for your help
Well i'm not professional, I only understand the rooting process.
But I have some questions:
1- can I make a ftf file as a backup from my exist firmware, so when I decide to reverse the whole process and return my device back to its original state, without losing anything?
2- What is the recovery, is that recovery has any disadvantage or negatively affect my device?
3- I didn't find a firmware 23.4.A.1.232 with the same customization version which is 1288-7361_R3C

Is it possible?

Hey guys, I rootrd my phone about a week ago and installed Pie rom. However is it possible to get my previous original android and unroot my phone to be like I bought it?
Thanks!
Yes, if you download the stock firmware files from a firmware host (updato.com, sammobile.com) or from samfirmtool, then do a full flash with Odin, it will essentially be like it was factory new.
However the exception is the knox trigger, once tripped it can never be reversed.
Downgrading may require bootloader unlock and a custom version of Odin, otherwise you could flash an older firmware with TWRP to downgrade then reflash with Odin
