hi guys im coming to xperia z from htc one as the girlfriend has now got the htc one can i ask just a couple of questions
1) does unlocking the bootloader loose the bravia engine and can never be back on unless relocked
2) or does rooting the phone loose bravia engine
3) maybe a stupid question posting here but have i made the right choice giving away the one for the xperia z lol
thanks
1. Unlocking the bootloader erases your DRM keys so features like Bravia Engine or Gracenote will stop working. Even if you relock your bootloader, you won't get them back, they're lost forever.
2. Rooting doesn't affect Bravia Engine at all.
3. Not a stupid question at all, go for it, it's the best phone I've ever owned The only downside for me is the fact that I'll most likely never buy a phone that is not waterproof again... thanks Sony for making me used to waterproofing so quickly.

Well, they're both great phones, but to be honest I hate Sony for releasing XZ now. I love Windows Phone Lumia devices, I like other phones, but I just can't let XZ's design and waterproofing go... whatever flaws this device might have - for me it's just perfect for now and I hope they'll release another waterproof flagship like XZ in ~2 years.

hey if you haven't unlocked yet then check this out. There is a way to backup your drm keys and restore them including bravia engine 2. Still you have to decide if you go with the bravia engine and a locked bootloader or custom roms with an unlocked bootloader and the bravia engine missing.
Hi guys
I'm sony fan boy, i was previous user of galaxy s4, but however i had some very bad luck with the screen i broke it twice so i decided to sell it and buy a Xperia z1.
So on my S4 i had 300dpi, (changed it with custom rom before was 480), i would like to do the same, i also would like to mod the camera to get the 120fps and slow motion effect, and the mod to use a pencil on the screen as stylus. So what do i have to do ? without losing waranty ? in galaxy s4 there was "knox flag and counter flash" for example every time you would flash the smartphone it would void the warranty and Samsung would always knew that we had rooted our cellphone so my question is does sony have something like this ? ive read something about drm keys but i don't know what they are, but for now i just would like to root the z1.
By the way my model is C6903, version 4.2.2 Number of compilation 14.1.G.2.257
So guys, what can i do ??

DRM keys are related to Bootloader.. It will come in picture when u unlock ur Bootloader also if u want to use any rom except Stock Based u ll have to unlock the Bootloader..
There are several Rooting guide available try to search and read
For you the only suggestion just read and read and read the Xperia Z1 Threads and all the questions will be solved, its easy to just ask but batter to read.

Well, there's no such a thing over here as knox counter, however I never care about the warranty so I won't tell You what those DRM keys are.
Modifying device always needs root, so it will automatically void Your warranty (idk. if You can later make it like an untouched device, but I think so).
Enabling pen mode is very easy, there are 2 apps that can do that (or You can use init.d): Pimp My Z1 or search for pen enabling mode app on google.
You can record high FPS videos by using mode called "timeshift video".

Hello mate, check out this video:
This should clarify a few things
Dear devs and community,
Now that the xperia z has been out for a while, you might all be aware that there is the famous distinction between xperia z's with
(a) the non-unlockable bootloader
(b) the unlockable bootloader
Now the advantages on the latter one are that you could install custom firmware and benefit from the work of the xda community. To date I am not aware that there is any method to unlock the non-unlockable bootloader in any manner. I would really like to know if we could really do something for that portion of z users that would like to benefit from their phones completely.
Unlocking the bootloader does void the warranty but to this day and age, it's like as if phones are leased to the user and it is ridiculous that s/he does not own the phone completely. So please do not post anything like "it cannot be done etc etc".
What we require is some pointers in order to start from somewhere in the hope of removing this plague completely off the xperia's with locked bootloader. Hopefully this would be a thread that provides insight to other z models on how to resolve this issue.
The bloatware on the phones is incredible! A quick look through adb shell will instantly tell you what I mean. The only way of being safe is not to have a data / wifi connection on the phone. That is why custom firmware is a far better choice than official firmware.
I hope that something could be done. Thank you in advance.
Al

None of them have succeded fully at loading a custom kernel on a non-unlockable device, or unlocking the device's bootloader.
An alternative would be hijacking ramdisk and loading a non-stock-based ROM on a stock kernel, as they did on the Xperia SP:
XperiaSP Locked Bootloader (LBL) Cyanogenmod 11.0 - http://forum.xda-developers.com/showthread.php?t=2735975
I've tried porting the solution they used on the Xperia SP, but I have nowhere near the amount of knowledge to get something like that working. Though, if some experienced dev would look into this solutions, maybe we would have some results
Even if Z's bootloader is unlockable, i think you can still flash custom roms with it. there are custom roms which support locked bootloaders, but of course they use stock kernel. hehe
Thing is we have to look further. There must be a solution. Nothing is impossible to this community. Thing is even as has been posted above. Only stock kernel can be flashed. Rooting is cumbersome as well which is mandatory on such a phone. At least as of the kitkat update u got to play about a lot to root it. Wondering why there was no rooting exploit lile cfroot for z out yet.
Rooting the z is simple, even on kk with locked boot loader - see here http://forum.xda-developers.com/showthread.php?t=2783863
Making permanently locked bootloader unlockable is a different story. The devs with the know how would have little incentive to pursue such a task. They would have bought z's with an unlockable bootloader, and unlocked it almost immediately.

True. I was hoping that the Xperia T bounty thread (I mentioned it above) would be of some motivation to devs, and help us fix the problem. But it seems that even 400$ wasn't a big enough motivation (or it's just impossible to do)

Nothing is impossible for this community. There are many people out there who could not buy an unlockable z and hopefully we could make such hardware more usable.

NOTHING is 100% IMPOSSIBLE anywhere. The creator of the universe COULD be a flying spaghetti monster, and Santa Claus MIGHT be real. LOL.
But some things are just VERY improbable.
Never mind sacharine images of "community". What we have is LOTS of people who want things but can't do them themselves, and relatively few people who can actually do those things.
A company developed an unlock for One M8 and NOBODY else can figure it out. They bricked FIVE M8's getting it working. They charge $20 and get LOTS of grief from people whining that it should be cheaper, or free.
BL locks these days are often VERY hard to crack. Each time crackers attacked in the last few years, the OEMs got smarter and put in more safeguards. Gone are the days when ANYTHING could be unlocked.
In the grand scheme of things, $400 is almost nothing to a high caliber cracker, and pledges are often MUCH bigger than real life payouts. A good SW engineer can make $100k per year in the first world, $400 might pay for 4 hours, once all sorts of common sense deductions are made.
I made SURE to buy my Z, Z1 and Z2 tab from non-carrier sources that leave BL unlockable. Others should do the same, or at least learn for next phone.
Remember the time...!
Guys,
I owned a Xperia x8 ho, this old phone has its glory, rip x8...
I tought there was an unnoficial way to unlock it's BL, by the Windows console,
Why not look in there and see if something can be done for the Z?
With the x8 we only had to verify the volttage/date (correct me if I'm wrong)
to see if the exploit was possible, why not try to do the same on the Z?

I can't find back the original thread but I can assure you that my X8 is UB unfortunately it dates:S
I think our best bet is to try and get CM (or AOSP/PA) working on a locked bootloader, using the ramdisk hijack method. It's been done before on the Xperia SP (and open-sourced), so I think it should be possible for the Xperia Z too (just my personal opinion, I'm in no way sure that that would actually work but considering the similarities of Sony products, it might be highly possible).
I'm just too unexperienced to do it myself atm, but I'll still try when I find the time.
This should be of interest.

Hey there.
I'm new to the Xperia scene, before I had various Samsung devices since the S1.
This means I'm pretty spoiled. The first thing I usually did on my S devices was rooting and installing CyanogenmodLineageOS, and it always worked flawlessly.
Now coming to the Xperia devices, what will the problems be that I'll face?
From what I've seen in the guides section, unlocking, rooting and TWRP is possible and already available, but there are some caveats with unlocking (loosing some proprietary features).
Second, what are the chances of getting LOS for this device?
im also new here and this finally looks like my kind of smartphone. Its small, premium and has pretty damn good features including a headphone jack! Currently on a OnePlus 5 and its.... okay? They really cheaped out on lots of things to make the stupid camera better which it still kinda sucks. Especially the glass on the front.... ive got scratches galore and it sits in my left pocket ALONE CONSTANTLY. the fact that it has any scratches is bullsh**.
Enough ranting, I'd love for this thread to get more attention! I just really want to know what this thing will cost. hopefully under 500.... or even less than that. Its a tiny phone cmon price tag.... wondering how this battery will do and what kind of dev support it will be getting! definitely will check up whenever this thing comes out
Where do you see the root is available? There is only a bounty thread to someone find a rooting method. And I think due to Android 8 and it's new features it will be not easy.
So for now accept the Sony stock ROM, Sony makes pretty clean ROMs so it should be a joy for you to use something new
About loosing some functionality (like Sony DRMem photo processing, Track ID license etc.), on previous Xperias you loose these functions only when you're unlocking the bootloader. If there is a rooting method with locked bootloader then you loose nothing (for example on Z3 Compact).

With Root, I was referring to the "All Things XPERIA" thread, and to unlocking the bootloader.
Should be no problem to achieve root like that, however then there's the DRM-stuff...
The ROM itself is fine, but I tend to rely on some things like Titanium Backup and Tasker.
Guess the Xperia line isn't the best choice for me after all.
Shame cause I already preordered ;D

Bare in mind that is a general reference for previous devices and until XPERIA devs get devices with Oreo then it's going to be a waiting game.
I have just received my device, upgraded from a Z3. Can I root without losing DRM keys / Camera quality? If so whats the best method currently.
Thanks
At this point, no. There's currently no method to backup the DRM keys, although there is some slow development going on.
And since you're coming from the Z3, which I also previously owned and have rooted, you should be aware that with newer generation of Xperias, it's no longer an issue of losing special camera features without the DRM keys, you actually lose the ability to use the camera completely.
So, general advice is to NOT root unless you understand the risks and am willing to accept the trade-off for whatever root functions you're seeking.
that's unfortunate - used to have a Z1C and will only use a compact phone, but Sony's antics have kept me from purchasing the XZ1C and XZ2C until bootloader unlocking and root is available

Well, unless you purchased from a channel that deliberately locks the bootloader (usually carrier devices), it's actually super easy to unlock the bootloader. They have a dedicated website for that, with a list of unlockable models.
Getting root access after the bootloader has been unlocked is pretty much trivial. So, your assumption is technically incorrect. Unlocked bootloaders and root have always been available for a huge chunk of their lineup.
The problem lies with the way they treat an unlocked device. They designed some of their proprietary software features to be DRM-reliant, and purposely wipes the DRM keys when you unlock the bootloader, possibly to "protect" their IP/assets. That was not such big of an issue in the past when you'd only lose things like enhanced low light picture taking ability or enhanced image reproduction (X-Reality), but recently, they've opted to be a **** and intentionally cripple core functions like the camera. That's the price you have to pay to root your XZ1C.
Fortunately, there now exists workarounds to that problem thanks to devs here on xda, so that you'd regain those lost functions after root with mods and hacks, namely a DRM-fix patch that tricks the OS into thinking the DRM keys are still there. Bad news is, this patch is no longer free, you have to pay for it. Also, you're pretty much at the mercy of the dev for any compatibility with future firmware updates. IMO, it's not worth it.
Alternatively, you can choose to build and flash AOSP, which Sony actually makes available on their developer website. From what I remember, someone reported that the stock camera does function, but is very basic. Basically, it takes ****ty pictures. Plus, the ROM probably not as stable since it's not meant for mainstream usage, I doubt they have people fixing bugs or whatnot.
But, the point I wanted to make is, the XZ1C is fully rootable, not completely locked down as you thought. With compromises though.
thanks. i'm aware it is rootable, but sacrificing camera functionality to achieve it (one of Sony's few strong suits among other oems) is a tradeoff few will be willing to take. either way, just feels like Sony keeps stabbing themselves in the foot with their mobile business
i wasn't aware of the (paid) DRM patch though, thanks for pointing that out. is this the one you are referring to? https://forum.xda-developers.com/xp...ny-xz1-compact-16-january-2018-t3736068/page4

janjan's kernel has the DRM fix built into it as well as some other mods. It's not the orgininal DRM fix made by sToRm// and started on his Sony Xperia XZ Premium TWRP + KERNEL + ROOT + DRM fix/restore thread
You can purchase his updated patcher from his website
The advantage of Xperiafix is that everything is bundled in one app which you run from your PC, as long as you have the right drivers it'll do everything for you. Compare this to janjan's kernel method which looks pretty fiddly.
Edit: I used sToRm//'s patcher to root my XZ1 compact, so I can verify it works perfectly and camera is as stock, no loss of quality.
