flashing xz premium from unlock bootloader to stock rom - Sony Xperia XZ Premium Questions & Answers

hello ,
excuse me, how do you flash xz premium firmware that has been unlocked bootloader but not rooted? now on firmware security may and want to return to stock rom.
thank you

use Xperifirm to download the firmware, then download flashtool and newflasher. decrypt the downloaded files with flashtool and then put newflasher files into the decryped firmware files. run newflasher and follow the steps. will have to use drm patch after flash new stock firmware if bootloader is unlocked. you can find all those software on xda.

thank you for your answers. There is an additional question, can xperifix v2.5 be used for the latest patch firmware? because the latest xperifix requires paying.

[Q] Where do I download stock (newest software) for Xperia Z3?

Hi
I just got confirmed by Sony customer service that after unlocking bootloader and rooting, you can still update your device with flash tool. But is their any website, like the one for Samsung, where you can find official and newest software updates and download them, so they're ready to be flashed to your device?
Thanks in advance

Out of curiosity, they're outdated stuck right?
I mean they're outdated and so. Aren't their an website with the newest possible updates?
I mean like the D6603 model, haven't been updated since september so any minor updates since are "lost" on the device, right?

I know that. I ask where do I download the latest version of the Xperia z3 software in the future.
Like if I unlock bootloader now, and Android L comes out tomorrow, I can't get it, cause I can't update with PC companion or OTA update. Neither can I flash it with Flashtool as I don't have the update. So back to the question. Where do I find new updates?

You cannot install the update with this after unlocking the bootloader but this is where you download the very latest files and then you can convert them to an FTF file and flash them with flashtool.

You have already been given the link to the FTF collection thread in an earlier post. That is where you get the latest FTF files.
Or do what I just said, use PCCompanion to download the update, convert it to FTF and flash with flashtool

What's about using XperiFirm with Flashtool? So u'r just up to date without having a look into forums etc.... That's my prefered way to stay up-to-date for all of my Z to Z3 phones.

Should I re-lock the bootloader?

Hi everyone,
I have D6603 with with Android 5.1.1 (23.4.A.0.546) with an unlocked bootloader (done per instructions on Sony's website).
For a while now I've noticed that the device overheats when I use the camera for a few minutes. According to this article,
the new update Sony have released, is supposed to mitigate the problem.
I cannot update my phone to the new Android version, because of the unlocked bootloader.
Can/should I re-lock the bootloader? Or is there a way to stop the overheating issue?

Thanks for the info Beetle. May I be so rude to ask you, where I can get the most up to date flashable ROM?
I did unlock the bootloader, but never managed to install a recovery mod or get root.

In flashtool theres a button labelled xperifirm, if you click that and follow the instructions you can download a ftf directly.
As for root and recovery, you can use this guide http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056 , and then create a pre rooted 5.1.1 firmware from here http://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904
Or you can install androplus kernel http://forum.xda-developers.com/z3/development/kernel-andropluskernel-t2925999 after you upgrade to stock 5.1.1 with fastboot, and skip the whole downgrade to kit kat which would be alot quicker.
Wow, that seems easy enough. I'll try it later tonight. Thanks again!

No worries, good luck. You may have to disable virus protection to download xz dual recovery installer, well, I have to anyway, my VP doesnt like the install.bat file.
EDIT: isn't the .546 the latest?
Not sure... My phone tells me there is a system update, but it always fails because of the unlocked bootloader.

Nougat is not compatible with flashtool yet.
Yeah, learned the hard and annoying way.
I had to find an old marshmallow firmware and then OTA upate that. Thankfully I found a central europe one that I wanted anyways.

Ok, thanks. But with an open bootloader a OTA update is not possible... Or think i wrong?

Correct, you cannot update OTA with an unlocked bootloader.
So, you should re-lock it, flash a MM FTF and then do the OTA and unlock again.
Just use the updated flashtool (v0.9.23.0) to flash a 7.0 FTF
According to the changelog on Flashtool website, it now supports Nougat. Try re-downloading the latest (0.9.23.0) from: http://www.flashtool.net/downloads.php

That´s it The new version comes on the right time for me !!!! Now it´s possible to flash the newest Nougat-Version with the Flashtool. Great. Thanks for your note on the right time for me!
It actually does not work for me at all, need a second opinion and more testing with this latest flashtool version

If you can download a MM firmware and flash that using flashtool you can root without unlocking the bootloader.

Yes, that is what I said. There was still a vulnaribility in the MM firmware (Dirtycow) so if you can find a FTF for MM, then you can flash that with flashtool and use the dirty cow exploit (Thread in general section) to root.

can you give a link for the method? pls
Hmm,,
Looking back I can only see threads about temporary root. I was positive you could root on marshmellow….maybe some more gooloing required
I have searched for it on Google and the results are only for those who have ubl yes, but is there really a way in this forum?

Yes, you can achieve temp root on marshmellow, that is how the TA backup tool work. I was pretty sure from there you could install arecoevry and flash a stock based rooted rom with a stock kernel. So its a system root not a kernel root, but this is going back a couple of years as since nougat this exploit was patched and only unlocked bootloader root was available.
But there the XZ can be downgraded to MM so its possible.
Oh, I've found it, maybe later I'll try it ... Thank you for the help bro ...
since xz came out on Android 6.01
so downgrade to ADROID 6.0
extract DRMKEYS ( TA.IMG)
UPGRADE TO ANDROID OREO
UNLOCK THE BOOTLOADER
ROOT IT
AND RELOCK THE BOOTLOADER AGAIN WITH TA.IMG
just give me the android version you wana stay and i will send u modded kernel, the one given in the post has universal drm fix! and if you relock your bootloader it will go in to bootloops!

If you relock the bootloader you cannot use a modded kernel. You have to keep the bootloader unlocked.

What about Android 7.0 bro? Is it safe to extract the drmkey? And Is this method safe for XZ docomo?

No, can only be done on 6
But I searched Google for backup TA but the conditions must be rooted, whereas I want to backup TA for root

Yes, on android 6 you can temporarily root to backup the TA, then you can revert back to any version of android and unlock the bootloader to flash a custom rooted kernel to gain root.
However, if you restore your TA it relocks the bootloader, meaning only a stock unrooted kernel will work.
So, use flashtool to flash a MM FTF and use the TA backup tool to backup your TA. Then just unlock your bootloader and use a custom rom.
Ohh now I understand, thank you for your explanation bro and I hope I managed to try it

Sony Xperia XZ2 TWRP Rom

Hi all,
I am urgently searching for a TWRP img for an Xperia XZ2 compact (H8324) Oreo (Android v 8) build number 51.1.A.4.225
Could someone please point me in the right direction?

Since TWRP is not official for Xz2c, you will need to rely on custom builds, or build your own. Only one I know of for O is here - https://androidfilehost.com/?fid=11410963190603893744 - by @MartinX3. It's for a different build, but I think you should be able to update build without wiping data, and be OK. He also has a corresponding ftf here -

Ftf is the flashing file that contains all of the information and files to flash a stock rom on your phone.
To root, just flash the ftf, and then follow the instructions in MartinX3's recovery thread here - https://forum.xda-developers.com/xp...recovery-twrp-3-2-2-0-touch-recovery-t3821597.
To flash the ftf, you need to use Flashtool by Androxyde or Newflasher. They each have their own threads with instructions / support.
If you use Flashtool, you'll need this - https://forum.xda-developers.com/xp.../flashtool-android-pie-52-x-fsc-file-t3896454

You really should read up on the process since bricking a handset is really easy, and your questions show a lack of understanding. TWRP is not a ROM, TWRP is a RECOVERY. Your phone has a bootloader, a recovery and a ROM (the operating system). You can only change operating systems (a different ROM or a rooted ROM) by changing the recovery which enables flashing ROMs, and you can only change the recovery by unlocking the bootloader. Screwing up any of those steps can brick a handset.
XDA is chock full of information and the poster above gave you directions for several helpful threads. Read these carefully and most of your questions will be answered.
