Boot Loader - Sony Xperia XZ Premium Questions & Answers

Just wanted to ask if Sony has been supporting the dev community recently with unlocked bootloaders, and other reasources? I have not used a Sony phone since the Z2. Loved it and it's past due to upgrade. I would like to consider this phone or perhaps the next OnePlus if I can wait that long.

Yes, Sony always provide unlock bootloader through website and their kernel source is readily available

Need to see the XZ Premium in this list, hopefully soon https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Don't want to run without locked bootloader and no-root for long.

When unlocked the bootloader do you lose some functions?

[Q] How to go back to latest stock ROM?

Hi. I just got my Moto G few days ago and I unlocked bootloader, rooted etc. So because of unlocking bootloader I guess I will not be able to get official motorola updates any more. My phone arrived with kk already, but I had some OTA update as soon as I turned the phone on and now it runs on 176.44.1.falcon_utms.Retail.en.GB. Now I want to explore some custom ROM-s and my question is how to go back to this ROM my phone is running on right now from custom rom? In this link http://sbf.droid-developers.org/phone.php?device=14 I can see that the latest ROM I can flash is Blur_Version.174.44.9.falcon_umts.Retail.en.GB. As 176 is higher than 174 I guess that my phone is running on latter ROM.
In general, is there a way to update to latest stock ROM-s from Motorola after unlocking the bootloader?
Yes you can! I recently flash that particular UK ROM and even though it was 4.4.2 I still got an OTA update which had "rare network drops, low sound and etc" in the changelogs, so I'd assume it's the same one you mentioned earlier in your post. Also, I should mention that I didn't receive said update on my Retail Asia ROM or on GPE ROM (that's what I'm currently on). So in the nutshell, unlocking bootloader doesn't stop OTA updates rooting does.
That is good to know, thank you, but why would rooting itself stop OTA? Usually devices lose drm keys after unlocking a bootloader, I don't see why would rooting itself wipe drm... I guess you don't lose drm after unlocking bootloader than... That is very kind of Motorola.

Well the unlocking bootloader procedure is mentioned on their own website, so that could be it I guess?.

Nope but root is available if it has a unlockable bootloader. Xa isn't in the Sony open devices project with it being a mediatek powered xperia either. Besides modified stock is much better than cm or aosp I think personally from previous experience with xperia custom roms.
I'm more than happy with my xa even without root(no way to back up ta keys currently)

Yes you right, stock rom is good and updates make the phone better. As you said before XA is a mid range device and is not supported by Sony Open Project, the phone is open enough to cook some rom but we don't have any dev in the place... I tried to port/build CM13, I found almost all sources but I don't have skills to built and debug it...
Will there ever be a way of rooting without unlocking bootloader?

Doubtful, all xperia devices released since z3+(with the exception of the m5) all use dm-verity security and device encryption and have needed a unlocked bootloader to gain root access. This isn't such a problem with the other xperia devices as thru all have ways of backing up the drm/ta keys. It's not currently possible to back up the drm/ta keys on any of the x range as they all come with mm not lollipop. One of reasons I've been using a stock xa since July, I'm not prepared to loose the drm/ta keys permanently made that mistake before.

Nope, currently not possible to back up drm/ta keys on any of the x range and none of the z5 ways will work as all the x range has mm out of the box. It's currently either wait in hope that a way to back them up is found(what I'm currently doing) or unlock the bootloader and loose the drm/ta keys permanently and voiding the warranty in the process(some people aren't bothered) I've made the mistake of permanently loosing ta keys before won't be doing again.

Getting the XA today from 3. Guess it will have 3 bloatware all over it and old firmware with slow updates. Is it possible to use Xpedia Companion to flash a stock firmware and rom?

Yes just done the exact same thing on three myself, got sick of the extra stuff three added plus they haven't updated to 33.2.A.2.93 yet so I've flashed the customised UK firmware. Battery life is much better than the three firmware too. Best thing about three xperia devices is no worries about not being able to unlock the bootloader if you want too though there's no ta key back up possible on the x range

No that is will only reinstall the software already on the device if you do a software repair or update it if it is a update.
You'll need to use the latest version of flashtool to download+create a ftf of your choice and then flash it takes between ten minutes and half hour.

Thanks, so 3 XA phone is unlocked meaning I can use flash tool to download the latest Sony rom and get normal OTA updates?

Flashtool works on totally stock devices no root or bootloader unlock required. It downloads the firmware from Sony's own servers(they only keep current versions though) and yes you'll still be able to get updates as your not rooting it or unlocking the bootloader or modifying the system in any way. Three only supply sim free network unlocked devices for all there handsets payg or contract they just add there own bloatware to it.

I'm afraid that isn't true, connected the phone, it recognises it with firmware version 33.2.A.73 but says, This phone is locked etc etc. Gutted, looks like I'm stuck on dodgy old firmware, thanks anyway

Take note of the date in the image posted, trust me there network unlocked and bootloader unlockable one of the main reasons I have a contract with three its how I got the xa as a upgrade had a unlocked m2 from them previously on contract, flash customised UK firmware via flashtool(which is nothing to do with xperia companion) or don't believe me and stay as you are waiting for three to push the update which they don't even have yet I've checked with them they knew nothing about 33.2.A.2.93
I have the exact same device as you but I'm now running 33.2.A.2.93 customised UK firmware rather than 33.2.A.2.73 three UK firmware
Feel free to check the firmware releases below

Strange... I have USB debugging set, oem unlock set, run flash tool (Emma) and after 30 to 60 secs says the phone is locked. The correct phone model, the imei and firmware version are shown (greyed out) Have I missed something?
I know 3 phones are unlocked to networks, don't think my bootloader is unlocked

Flashtool is totally separate to Sonys EMMA software Emma is Sonys official software for unlocked bootloader devices only.
Flashtool by androxyde is totally different and works on totally stock devices.
The bootloader is unlockable as mine is but it comes locked you need to email Sony requesting a unlock code and follow the instructions, unlocking the bootloader also voids the warranty.
My Xperia needs to be off and oem unlock checked and it should be fine
Try following this guide if you want root and unlocked bootloader

In waiting in hope for a way to back up the ta keys before I unlock mine made the mistake of loosing my ta keys before.

No should be fine the firmware is identical just three add way too much useless stuff to it, I'm on three UK but now running customised UK firmware much less pre-installed bloat than three's firmware. Battery life is much better too

Enable the aggressive doze and doze on the go feature via adb in greenify, it makes doze more like old stamina mode. Gives you full instructions on how to enable it in the app. After using both three and customised UK firmware, the customised UK is definitely the better of the two. Glad to hear you are happy three must of only just got the firmware from Sony as a week ago they knew nothing about it. Why I ended up with the customised UK firmware

[Question] Bootloader unlocking

Hi,
I'm considering investing in a Xperia XZ, however, I wish to unlock its bootloader in order to root it and also install Xposed.
I remember, back in the days of the Z3, unlocking your sony device meant giving up on some camera features.
Do you know if it is going to be the case with this model ?
Thank you in advance for your answers.
Regards,
Azsde

Yes it's still the same, loss of bravia engine, x-reality, it effects camera performance in low light conditions and probably more. There's no way to back up the ta keys on any of the x range currently and probably never will be either so once you unlock the bootloader there gone forever one of the reasons why my xa remains stock still after 3mths made the mistake of loosing ta keys before won't be doing it again.
You'll need to use a modified kernel with the drm fix.

Is there any reason to backup ta keys if the modified kernel has drm fixed?
If I recall correctly, the T-Mobile Z3 had a locked bootloader, but could still be rooted. No keys or features were lost. So it may be possible with the XZ.

Yeah, but it requires a security flaw, and still prevents me from installing a custom recovery and xposed
You can use the towelroot to exploit the XZ from what I've read however will be trying this later to confirm.
Exploits will come just a matter of time for one to be made .

Sony Xperia Z3 Compact D5803 Rooting

Hi all
I have been looking into rooting my z3, then moved onto bootloader unlocking and hit problems at every stage. Ive come full circle as to why I was doing any of it, so thought I would ask some advice.
I was originally looking to remove bloatware and get rid of Google chrome so I can connect to internet without such spyware and load a honest browser. In order to do this It seemed I needed to root phone, in order to do that I needed flash capability, in order to do that I needed to unlock the bootloader. My configuration says "Bootloader unlock allowed : No" which seems to be a problem.
I have been round and round in circles trying to make progress on this, So I thought I would ask for some advice. All I wanted to do was load Firefox and stitcher.....am I asking too much???
It seems like am I asking too much!!
No one got any advice at all then....?
Well thanks for that people, that was really helpful.
