Hello everybody
I have a question to our wonderful community an i need answer please
perhaps many other ask the same question here but i didn't find the answer
Dose unlocking boot-loader affect camera in Z3 and is it true that the voice properties will be changed
may be some of you will find it silly , but really i need answer and thanks in advance
No, but you will lose sony's DRMs, meaning you won't have image enhancements, for example.
If other than unlocking the bootloader, you also want to install a custom ROM, the camera WILL be affected.
Either way, make sure you back up your TA partition before unlocking the bootloader.

Sorry for asking, but i tried to find out and couldn't find it, therefore could someone please tell me what are the things which don't work after unlocking the boot loader along with any side effects??
Nothing, everything should be normal
I've been watching the developer board regarding the root and locked bootloader issue, and I've spent hours researching this and have yet to find a solution that's known to work without loss of something, likely a permanent or semi permanent loss. My device is a Z3 model D6616. I'm unhappy with the phone for several other reasons, but haven't owned an un-rooted phone for some time, and prefer keeping this phone if I can root it successfully. Root with stock firmware is my objective and am only interested in responses from people that have themselves rooted (and dealt with bootloader issues) a Z3.
- Root phone installing current T-mobile stock firmware.
- Known loss of function: Sony DRM dependant features/funtion only (from memory, mostly related to camera low light performance and DRM playback issues)
- Other loss of function experienced with stock features, or any other problem with any other app. Especially concerned with root dependant features of Play apps? Also ad blockers?
- Waranty loss (potential) and loss of OTA updates understood.
- Feature/function loss with workarounds or fixed that survive power cycle?
- Expect permament bootlocker inability to relock
- A link to the specific process you used, any problems you encountered whatever the cause. For example it usually takes me at least 3 attempts to root using any complex process, and I always read through 5 times before starting and download every needed file and program in advance.
Again: Sony Xperia z3 D6616 T-mobile
Firmware: 4.4.4 23.0.3.1.123
Software: D6166 R16B
In the past, I've had the most problems when an understood part of a process is not explicitly stated, or I've ignored or misunderstood a step. Plugging and unplugging from usb to PC a typical example. I don't have the technical know how to critique or ignore, so always attempt to follow all instructions without variance. I've had some problems, and most were solved by starting the process again. I hesitate to ask for help since the last time I did that I was attacked for witholding information when asked if I had backed up the phone. Since i didn't have access to the PC at the time of the question I honestly answered I didn't know (since I had attempted to but couldn't confirm). If you've ever answered a question here implying the request or requester is stupid or dishonest, I'm fully aware of my ignorance and my own integrity, and other personality traits, so please ignore this request, which accepts my lack of knowlege and has no tolerance for your issues not previously resolved through your own peaceful and respectful process.
Please only respond if you have personally rooted this specific phone model. If you have not, but know someone who has, please ask them to review this post and respond.
Nobody has rooted this phone without unlocking the bootloader. If you unlock to root, you will permanently lose DRM keys from the TA partition with no way to recover. No current root method works on 4.4.4 on the Z3. No one knows when or if an exploit will be found. We all want root. If you want it now, unlock the bootloader. If you can wait, wait. It's your call either way. As soon as a root method surfaces, best believe it will be in these forums. I'll be waiting with you...
First of all, check *#*#7378423#*#* to see if you bootloader can be unlocked or not.
Coz I think 6616's bootloader is unlockable.

This is true. D6616 owner here, T-MO not unlockable yet :/ eagerly awaiting root as well as I really enjoy the z3, maybe even more than my Nexus 6 (gasp, blasphemy!)
Thanks For the Responses
freddy you addressed my concern, exactly. My phone reports:
Rooting Status:
Boot Unlocker Allowed: No
Although variants of the z3 have been bootlocker unlocked and rooted, I have not found a clear claim that was successfully done with D6616 z3. Since I'm a new T-mobile customer, this and their attitude about it are a poor way to start. I have a HTC phone I haven't returned, maybe I can get them to take the Z3 back instead. While I have benefited from and appreciate the great work so many people have done to make our phones usable and available to us, I've seen how carriers, mfgs, and users push good phones to market crippled by junk and unecessarily locked down. it's time to consider the mamufacturers that have been successful building good phones and selling in places like China at much lower prices.
Regarding any loss of DRM, I couldn't care less. This phone takes worse low light photos and video than my rooted Samsung G3, making it functionaly useless to me. Add to that the lack of a rational UI for telephony and IM, and done with Sony.
To be clear, if the bootloader can be unlocked and the phone can be rooted and you have done this yourself, please post.
Well...
I think there is no way you could unlock the bootloader of 6616.
The only way is to wait for the root on locked bootloader.
Check here http://forum.xda-developers.com/showthread.php?t=2940539
But that means you have to stick in the .93 firmware, even if the exploit is also usable for Z3.
Or return your 6616 and buy a 6603 or 6653 variant.

I'm similarly confused about this whole thing, this new Giefroot program means we can all potentially get root for our devices, but we still lose the DRM keys right? So that means we can never have the Sony camera/image processing processes back again right?

NO
Unlocking the bootloader = loss of DRM
Rooting that does not involve unlocking the bootloader means you keep the DRM keys

Thanks, I'm new to Android and this is all over my head. To clarify, Giefroot does this without unlocking the bootloader?
It's all pretty frustrating, I gotta say... I'd love to install Cyanogenmod on this, but losing key features on the device is a pretty harsh trade off.

Yes, giefroot does not unlock the boot. There is only one way to do that and that is to obtaining the code from sony and fastboot it either manually or using flashtool.

Hi all.
I've got my XZ since one week now, and I'm missing the possibilities of rooting my device.
My Z2 was LB, so I never could ever try to unlock my bootloader. therefore, I don't know anything about it.
I've read a lot of thread here and there, and some points are not that clear to me.
Will the procedure of unlocking the bootloader erase everything in the phone (like photos, contacts, etc...)?
Unlocking the bootloader will kill the DRM keys forever, if I understood well. but flashing Androplus Kernel will recover them, right?
Is it possible to relock the booltloader after? if yes, will the DRM keys be restored?
Last thing, to be sure of what I should do.
1-unlock the bootloader with IMEI via sony site.
2-install TWRP via adb command
3-flash Androplus kernel.
Am I right, or do I miss something?
Thanks for your help, and sorry for the noobish questions.

Hey sensei_sai,
Im unsure if unlocking will erase your data but its always best to backup everything in the internal memory just in case something goes wrong.
Androplus will NOT recover your DRM keys but kernels with DRM fixes try to replicate the features that are permanently lost as a result of unlocking your boot-loader.
In the future it may be possible for you to re-lock the boot-loader but even then this wont restore DRM keys, the only way to restore DRM keys would be to back up your TA partition (This contains your DRM keys) before you unlock your boot-loader but to do this you need root access with your boot-loader still locked.
How to backup TA
Unfortunately at this time nobody has figured out a way to get root with a locked boot-loader although a newly found exploit (Dirty cow) may help us do this very soon so if you care about re-locking and keeping your DRM keys I advise waiting until a locked boot-loader root solution is around!

Thanks for your reply.
Too bad for the TA partition.
So we have two possibilities. Take the risk of loose some features forever, but benefit of the root or wait till someone make some magic to use an exploit to obtain root without unlocking the bootloader.
Risk and go... Or wait and safe... Dilemma...

I think that the era of DRM lock is over, we've been using DRM fixes for all the latest xperia phones, the dirty cow is a bad exploit and it's more dangerous than useful.
I was unsure about unlocking the bootloader but now that I did it, I rooted and I regret nothing, the only downside of unlocking is the warranty loss, but who cares as long as the phone doesn't magically explode.

OK, so did the bootloader unlock erase your data? Did you use the sony way or Flashtool?

Thank you, I've seen that guide, seems like it's not possible to unlock bootloader without factory reset.

Yes, but it worth it!! Save all your datas and go for it!
Sorry if I am being redundant, but reading about all the different opinions and suggestions about unlocking the bootloader didn't bring me anywhere.
So, I own a D6603, BL is locked, DRM keys are intact, rooted after downgrading to KitKat and then flashing a Sony based custom ROM (Fragment ROM V4.2). Now I'd like to get past 6.0.1 and try out the new Android. But to do so I need my BL to be unlocked. I've read quite a few posts about the topic and I am trying to reorder all the information. Please help and answer these questions, I really appreciate it
- Can I restore the TA partition with the DRM keys after unlocking the BL and flashing a custom ROM?
- Is there a point in doing so? Are any of the features protected with DRM used by custom ROMs?
- What if I wanted to get back a few Sony apps (say the camera or Album) in the custom ROM? What differences would I face?
- Do all the people that use custom ROMs out there run their Xperias without the DRM protected features?
- Some argue that there is no evident difference after unlocking the BL. Is this true for all firmwares, or does it depend on the single custom ROMs?
- If so, what differences can you notice on popular ROMs like Omni and Carbon running Oreo or Nougat? Especially considering photography and in-ear audio.
- What is the upgraded bootloader, and who wrote it? Does it imply that I will not be able to restore my DRM keys with it? If so, is there a way to revert to the original bootloader and everything stock?
I really hope that someone will take the time to clarify these few things, hopefully this will come in handy for other people too
Hello everyone, I have questions. I will be happy if someone could help me understand Android better.
Edit: find most answers here https://android.stackexchange.com/questions/21460/what-does-fastboot-oem-lock-do, the following remains:
Is locked OEM equal to locked bootloader?
If not, which is more serious e.g. undesirable when using rooted custom ROMs?
Is it possible that booting fresh custom ROM will lock bootloader (or OEM..) back without asking? just like this happened to me with stock firmware
Is it dangerous if bootloader gets locked and I use TWRP?
