Folks,
This is something we should keep an eye on:
FXP article: "Finally! Boot to recovery enabled in special bootloaders from Sony"

While coming from an Nexus 4 and waiting for my Z3C delivery to arrive.
I just read that bootloader news, too. Would it be useful to wait some time, if Sony releases some updated bootloader?
Or perhaps better to say, are there any huge problems / differences with the current procedure of unlocking the Z3C?
I already noticed the list for unlocking and rooting is very long with respect to N4 ....

The "unofficial" method of installing a bootloader is currently stable, thanks to many xda contributors (check this same forum for it).
But it's not officially supported by Sony and it involves a step that invalidates the device DRM keys.
You can (and should) perform a backup of the TA partition in order to restore those keys if you want to revert to an official firmware.
What is announced there may take some time for the Z3c, and it's not guaranteed to happen. But it would certainly make things easier...
So if you want to test a different rom, you should go with the current process.
(important: do some research on this same forum, follow the instructions, and start by backing up)
As to the device itself, you won't find a gadget out there comparable in specs and size.
IMHO, it's a default choice for a compact high-end device.
are there any news about the bootloaders?
Hello,
I had the impression of plenty of people unlocking their BL, like far more than 90%.
Now, as I thought about it, it came to my mind that I could be totally wrong about that.
Till now I thought, to unlock BL is like the normal thing to do, and maybe to relock if DRM was needed or DRM hack did not work.
Or, as in case with the latest DRM_Hack from Team HSxEXR, which is really cool! - if you forget to apply it after flashing, you maybe don't want to wipe data/factory reset after you already installed your apps.
So there are some cases where you just want to relock this thing.
But there are maybe some people who never unlocked it and went stock-based all the time? No custom kernels, no multiboot?
Since there is xposed, you can have a lot of things with any rom, if you can root and install a recovery. And there are the fantastic stock based ROMs which I prefered also a lot of the time, because of the better camera.
What is/ was your choice? Feel free to explain I am really eager to know how many of you never unlocked for example! Did you encounter any problems or could you use all the tweaks you wanted to install?
Unlocked 10 minutes after i arrived home with my Z2 XD
I haven't unlocked it and I don't want it because I'm totally satisfied with my stock based rom.
I don't even use xposed.
On previous phones I did both but I haven't crossed anything that would make me want to do it on my Z2
I haven't unlocked my bootloader. I just found the stock experience satisfying and trusted that Sony would still upgrade the software, which they seem to be doing. I use the #nochromo ad-blocking chrome browser and dolphin with an ad-blocker plug-in, so apart from YouTube ads I'm not bothered for root. Emulators run fast, battery life is good, camera is great (if you mess about with manual settings) and benchmarking to 49000 on antutu for what it's worth. Also I have a sony tablet & sony 4k android TV so I've left them all stock so they talk to each other fluidly. MM is only weeks away so I'm not even going to bother flashing the beta rom. And for the record I flashed both my HTC One X and HTC Desire multiple times, to account for the shortcomings in those devices. The shortcomings in the Z2 are so niggly and small that I don't see the point, in fact I have gone sim-only with my provider and refused an S7 Edge upgrade cos I like the Z2 so much!
:silly:
Kept a locked bootloader, only needed to have root.
Well,as for me,im too afraid to unlock the bootloader or even root.First,because im a heavy noob,i dont understand nothing ,even when you explain me,i will be like a girl which says "Ehmm,okay......".
The only thing i did is flashed my phone,thats the simpliest thing ever.My phone is still under warranty so i dont want to mess with stuff like that.
Unlocked it, the first day i got it.
Androplus kernel is must to get the full potential of the snapdragon.
I have LB, but sometimes I unlock for trying ROMs, I have a backup of my TA partition so I don't worry to unlock bootloader every time I want to try something

I did unlock my bl.
But I couldn't really notice a whole lot of difference, even with a custom kernel, so I relocked it by restoring my ta backup(make sure to take a ta backup no matter what). That was half a year ago though.
I might unlock it now that drm restoration is really easy, but I think that unlocking your bl does wipe your phone, and I am too bored to backup everything.
In all honesty, I don't think you are missing a whole lot by not having a custom kernel or a rom such as cm, as sony's software is already light enough.
However, I am guessing that there should be some gains via installing a custom kernel (overclock, or better battery life) so keep that in mind too.
Unlock and relocked several times already... No problems so far. Total freedom of choice....
Until the Xperia Z3, we still have the choice to keep bootloader locked since root exploit have been found.
But with Z4 then later Xperias you are forced to unlock your bootloader to root.
There won't be anymore root exploit for locked bootloader. We are lucky that Sony is allowing the unlocking of bootloader.

Could you explain why?
Isn't it possible that new root exploits are developed in the future?
A root exploit is basically an unpatched security issue.
No system will ever be secure, there are possibly even root-exploits out there which are not shared with anybody
(Zero-day-exploit).
Anyways, I like the way Sony is opening their boot loader for public... It's like nexus.
Unlock after back my TA up, for safety

Unlocked the bootloader was the first thing I did, after testing the Z2 for a few hours only to see that everything works.
I didn't even bother to take a backup of those DRM keys. Never goig to use anything DRM related anyway.
I needed to flash a minimalistic ROM without bloatwares.
I've unlocked it a few times, but the worse photo quality always brought me back to stock. It's a shame we can't have the best of both worlds

XDA did a very nice article about this a while ago:
http://www.xda-developers.com/a-look-at-marshmallow-root-verity-complications/
This line should be easy to understand: "In lieu of an unofficial bootloader unlock (those are fairly rare these days, short of leaked engineering bootloaders for a few Samsung devices), it seems highly unlikely that you’ll be getting root on Android 6.0 without some divine intervention – the combination of dm-verity (to stop your phone from booting with any modifications to the system partition), and the requirement for SELinux changes in the ramdisk (to let root work), look set to make things rather un-fun for root-aspiring users of these locked-down devices."
I'm so glad sony didn't enable dm-verity on the z2 mm beta or else root would be a HUGE problem for users with unlockable bootloader like me (z2 was my first sony device and i stupidly thought i could buy any z2 and request the unlock code from sony's dev site, so i bought it from vodafone at FULL price and got an unlockable bootloader as a bonus :crying: )
Like @niaboc79 said this things are EXTREMELY complex, technical and very hard to get around... and there's no one with the required skills on xperia sections as far as i know. I would gladly pay like 25/30eur to unlock the bootloader of my z2 if a sunshine like hack was available for it.
And to try and keep this still on topic i didn't unlock my bootloader just because i can't xD
I rooted my Z2 within a few days of owning it (coming from a Z1 which was a dud with horrible touch screen issues )
I proceeded to backup the TA partition and unlock the bootloader, and I have never relocked it, and I think it will stay that way for the foreseeable future.
To me, if the bootloader can be unlocked, it shall become unlocked
I'm currently on official CM12.1 with M5 Kernel, and that made me fall in love with the Z2 all over again, and funny enough this isn't the first time using a custom ROM like CM12.1.
I've used many ROMs on the Z2, from stock to custom and from KitKat to Marshmallow, and in the past there was always a catch in some way or another going to something like CM12.1 or anything based on it.
BUT, that isn't the case anymore.
Using official CM12.1 is just pure bliss. Literally everything is working just as well as on stock. It's like owning a Xperia Nexus, if such a thing existed
No random reboots. No lockups. No force closes. No errors. No bugs.
Awesome
So yes. Unlocking the bootloader was so worth it
Yes indeed, I also had a marvelous experience with 12.1 CM.
The only backdraw was that CM feels so "mainstream" and the ****ty "recovery".
This rom definetly ranges in the top 3 for z2 in my opinion.
There is one thing, that I miss on non-Sony ROMs if the camera is ok, and that is the small apps, yt/media-viewer in particular.
I don't like installing xposed if I don't have to, so the small apps are a nice way to listen to yt while screen off or using other apps in the foreground.
MOD EDIT by @gregbradley. I did not see the need for the expletive in the title, so i took it out for you.
So here's a little rant.
Read it if you'd like to, don't read if you don't like to.
Let's start with a little introduction. I've bought my Z3 about a year ago. I wanted to go with the z3+, but the Snapdragon 810 seemed to cause some issues. I still wanted the Sony batterylife after coming from a Galaxy S4 (which doesn't have the best battery life). I found online that Sony shares AOSP source code, so building a custom rom shouldn't be too hard.
Recently I have thought about unlocking my bootloader, but reading further into it, I found there to be NO upsides to unlocking your bootloader.
- There's a possibility of losing your DRM Keys when unlocking bootloader.
- You can not lock your bootloader again, so you're forever excluded from any OTA's.. Sony supports AOSP source code, you know.. to be developer friendly. But locking your bootloader again is not possible. This makes unlocking it very unappealing.. and very developer unfriendly.
- You cannot flash a recovery through fastboot, because Sony doesn't use conventional recoveries. Very developer friendly!
- Fine, Sony decides to release Android MM concept. Great, I was excited for this! But, the actual MM final firmware is nothing like the concept firmware and still a lot like the actual Sony themed firmware. (In my opinion this is disappointing, but that might be just me). When asked about why there are differences between the concept and the final firmware, the concept team replies that it has nothing to do with the final firmware. Then what's the point of a concept firmware??
Maybe I'm just nitpicking, but this seems very hypocritical from Sony..
C'mon Sony, your mobile department isn't doing too well, and this sure as hell doesn't make it better.
Now I know there are maybe only several thousand people actually wanting to run AOSP on their Sony, but I sure as hell am not buying another Sony phone until this policy changes.
Thanks.

Im still trying to figure out which part you unhappy about lol ?????
I have the Z3 rooted with Android 6.0.1 Slim1.6 Rom LB
And its the best ever with longest battery life ive experienced no issues fast and smooth
I dont want any other phone right now what more could you want?

My issue?
On one hand Sony releases AOSP code, while on the other hand they make it a real damn pain in the ass to even run an AOSP rom. There have been several developers out there to try and build an AOSP rom. None of them managed to make a fully working one, because Sony made it so damn hard. I find this hypocritical and unjust.
What I want is for Sony to make it actually possible to run an AOSP rom, and stop pretenting like it's possible.

You can use TA Backup to restore your DRM keys as long as you back them up before unlocking the bootloader ('m just about to do it)
You can install a custom recovery via fastboot (I used TWRP to replace cyanogen recovery).
Not really sure your points to be honest.

Sure, you can restore DRM.. but is it really convenient? My point is that Sony basically promotes AOSP roms by releasing source code, but on the other hand they make it impossible to enjoy a fully working AOSP rom because of DRM, camera's never working, etc..
Oh, and if you could explain to me how you flashed TWRP, and which file exactly, that'd be great . I've literally already spent 6 hours today trying to figure **** out after unlocking my bootloader..
Thanks in advance!
I totally agree with you. Building an AOSP ROM for Z3 seems to be difficult (Tried cm too but extracting proprietary blobs did not work). The way how recovery works here is pretty stupid, seeing that we dont have a recovery on N for example, so I need to be on it without root (i dont blame developers here, but again, Sony's implementation). Also I haven't been able to work around the radio or camera thing in AOSP, even though I have only been able to build the ROM like once some weeks ago

Also the recovery thing. Just download the .img from Nailyk's thread and put it in ADB folder. Then go to fastboot and type fastboot flash FOTAKernel . Then boot to recovery by pressing power and volume down button, releasing power when phone vibrates and volume when sony logo appears.

That is true and disappointing. However, there is a way to backup the keys and restore whenever the need arises.

fastboot oem lock or restoring the DRM keys should relock the bootloader.

I think the Concept software is for those who don't need Sony enhancements (X-Reality, ClearAudio+, etc.) and want something that is close to stock.
So:
-You can backup and restore DRM functions even with an unlocked BL.
-You can relock BL again (haven't tried it myself but I think it's possible, if you check out DRM restoration guides I think they also show how to relock the BL)
-The new Sony BL allows fastbooting recoveries, the older ones support FOTA recoveries (I've used both with no problems)
-The MM concept project is still live, you can install it and continue using it, it gets updated regularly and is very close to AOSP.
-True Sony is kind of shady with their sources but you can build AOSP, there are AOSP builds for the Z3 here: http://fxpblog.co/ they get released whenever Sony releases new sources but you can also make builds yourself. The only true issue with sources comes out on certain AOSP functions and that we don't have (yet) fully working CM13 builds. As for the concept firmware it's exactly what you said, Sony is giving it out to people who are interested in having a close AOSP experience with support from the vendor while giving feedback to further improve it. Sony is making moves and is becoming more developer friendly by the month, other than new and constantly updated sources, proof of this is the Xperia Z3 is the only non-Nexus device that gets to run the Android N preview officially given from the vendor.
The Z3 is a great device, I personally haven't regreted the purchase, the only thing that bugs me is that neither I nor anyone else has managed to build a fully functional CM13 build (kudos to infected btw).

As I said fxp has some builds, I haven't tested them but I think they work (http://fxpblog.co/)
I was eager to try out FXP's aosp ROM, due to 3.10 kernel and such, but I got an error about updater-script in META-INF, didn't read further. I have my suspicions that it was a bad download, but their current site is so slow to download from (about 2 hours to download, and only a +20kb/s faster if you register), and i'm not going to pay for that site. If it helps any, i just wiped data, system and caches and tried flashing the ROM.

Basically the error I get is with extract-files.sh. When I run "./extract-files.sh" while phone is plugged in, I get permission denied. The other option for me is to run it with sudo, but then I get "line XX adb: command not found" (many lines of this error). Someone suggested chmod or opening a terminal window inside the folder where extract-files.sh is located. There shouldn't be any errors with my AndroidSDK path, even though some suggest the error is with this.
Also the reason I'm trying to pull these blobs, is because the CM tutorial told me so

No worries.
So it may be a little more complicated.... If you just need a functional self build CM, try to include themuppet repo. If your device variant is not currently officially supported it can be more complicated.
I suggest you to open (or find) a dedicated thread and quote me, or join #[email protected]
Otherwise I'm following this thread because I found some point really interesting. I'm currently in trouble with Sony, that's why I subscribe.

Customer service troubles. They didn't respect law about unlocked bootloader into my country and refused to fix my device.
I know this thread is basically dead but I figured I'd poke it with a stick a few times and give my two cents.
First of all, the reason I chose Sony. I peviously owned Galaxy S4 and at some point (Android 4.2.2?) they implemented a security software called KNOX. It lets you create encrypted partitions for business stuff. Soon after, users started reporting that any unofficial changes result in a "0x01" flag showing in the download mode. Turns out, the device has a physical e-fuse which is burned and can not be reverted (except with a motherboard change). It was mainly for the customer services to be able to tell if the phone had been tampered with. But here's the catch - it was also triggered when installing official Samsung firmware using ODIN (basically FlashTool or Emma for Samsung). And downgrading firmware to pre-KNOX resulted in a special lock - the inability to upgrade again.
XDA members, such as Chainfire and others, have not managed to crack the software after several years, despite the bounty of thousands of dollars. I didn't think much of it, and rooted. Months after that my phone stopped recognizing the SIM card. And since I had "0x01" I had no warranty. So it went to customer service many times, I paid for the SIM reader change, and still nothing. Even custom ROMs didn't help.
So, I had a phone with no SIM support, and no faith in Samsung. I found out that Sony "encourages Android development" - bootloader unlocking and so on. Soon after I bought a Z3, and being a power user, I wanted to root. And then I found out about the DRM. The more I researched, the more livid I got. Finally I managed to dig up a method of rooting without bootloader unlock. After every small update Sony issued, I had to go through hours of researching and developing a new cusom update for my device. After some time I just decided to go with a (back then unreliable) DRM function restoring flashable zip.When I heard there will be no Nougat for Z3, I was quite mad. I looked into some AOSP's. NONE of them were working correctly. So I settled with a Z3 on unlocked BL with some DRMs working. The device has hiccups but is usable. I am disappointed in Sony and I am disappointed in Samsung. Never buying their phones again.
But now that @nailyk is developing LineageOS for Shinano devices, we have new hope! :victory:

So, I had a phone with no SIM support, and no faith in Samsung. I found out that Sony "encourages Android development" - bootloader unlocking and so on. Soon after I bought a Z3, and being a power user, I wanted to root. And then I found out about the DRM. The more I researched, the more livid I got. Finally I managed to dig up a method of rooting without bootloader unlock. After every small update Sony issued, I had to go through hours of researching and developing a new cusom update for my device. After some time I just decided to go with a (back then unreliable) DRM function restoring flashable zip.When I heard there will be no Nougat for Z3, I was quite mad. I looked into some AOSP's. NONE of them were working correctly. So I settled with a Z3 on unlocked BL with some DRMs working. The device has hiccups but is usable. I am disappointed in Sony and I am disappointed in Samsung. Never buying their phones again.
But now that @nailyk is developing LineageOS for Shinano devices, we have new hope! :victory:

Lots of OEM are doing this stuffs to protect their intellectuals rights with DRMs. AFAIK oneplus allow bootloaders unlock.
Just for fun, the TA partition of sony contain so much things... It is crazy! BTW I think we have fuse too
idk where you live but in Europe there is a law which basically said: hardware and software are separated and OEM need to fix hardware, except if they can prove this is user fault.

Hi all, I wait like all of you the Oreo update, but with this, a little new question brings up in my mind... So, the root?
Yeah, I don't know how it works properly but in previous cases on other devices (always Sony and not) when I update the android version, the root disappear. Or am I wrong?
Btw the real problem is, in positive case, WHO will do it?
Because the developer who create it, like the recovery, for 7.0 (Janjan) has close the project... At this point it is right to update a rooted system and lost root?
Talk about.
Janjan hasn't closed it. He stated in his thread that he plans on releasing updates for Oreo
So always root and recovery? Or directly a rom?
He stated wait for Oreo, then he will get out recovery, and kernel. Then all u have to do is flash SuperSU or magistik. No custom roms from him as he doesn't have phone anymore.
Perfect! Rightly I think he need it too :highfive:
Thank you man!
