Rooting with locked bootloader - Xperia Z3 Q&A, Help & Troubleshooting

Has there been an exploit found yet to root under a locked bootloader? Received my Xperia Z3 (D6603) today and found out the bootloader is locked. Unfortunately that rules out Cyanogenmod but I would still like to have root for Xprivacy and some other essential applications.

None yet.. I just wonder if there ever will be dev for this phone.. I miss flashing roms.

Have you tried installing the international ROM on it? and check to see if there are any root/exploit options for locked bootloader?

Unlocking the the bootloader has nothing to do with rooting. See the first link in my sig.

If it says bootloader unlock not allowed , then i doubt there is a safe way to unlock it.
Nearly every method to unlock such a bootloader are shown only for 2011 devices and i have heard 2012 devices have been patched to stop an unlock by that method.
Also those methods involve certain hardware modifications using bare wires and finding the debug port.
Such methods are highly risky and may damage your phone.

Yes you can root without unlocked bootloader, Framaroot worked without any issues for me, and i don't see any reason why it shouldn't work for you.

You can install Stock based custom ROMs without a unlocked bootloader.
This might help : http://forum.xda-developers.com/showthread.php?t=2237164
And regarding Non-stock based custom ROMs and overclocking, they are kernel mods and to flash a new kernel you need an unlocked bootloader, sorry

Will the T Mobile variant of the Z3 (D6616) ever get a working root?

I bought the Z3 recently coming from a rooted Galaxy S4 and damn do I miss a lot of the little features of the custom ROM I had. I thought I could do without the root but I really would like to have Carbon ROM again but on my Z3. Sorry if this has been asked many times before.

The D6616 has a locked bootloader, so no custom roms as far as I know. Only Sony knows how to unlock it. As for root, we must wait for another exploit that would allow root access on this version of the Xperia Z3. There's nothing else to do but wait.

Another exploit is not needed. In theory giefroot would work. However the parameters of the memory allocation are needed in order for the exploit to work. They can only be found from rooted devices (Hence why unlocked bootloader devices were asked for in the development of the tool)
As the D6616 has no unlocked bootloaders that info can not be found. It could be done by trial and error, if you have several years to try each one....

[Q] Xperia M2 Version Number

Ive found on few sites that my Sony Xperia M2 D2303 with Kitkat should be 18.3.C.0.37 but mine software version is 18.3.1.C.0.21.
Why is it like this? Is there something wrong with my device, is it fully updated to last software version or not?
Also ive checked bootloader unlock status and it says Not allowed.
In the official Sony site ive seen a text that says: "Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37." - which is different then mine.
I also checked for any updates but there is nonne showing in my sony app.
How can i solve this?
Thanks in advance.

Different terms, different topics.
Let's see, .21 build version number means 4.4.4 KitKat (most updated version of KitKat).
If the unlock allowed device says No, it means you have the SIM Locked, so, you need to contact your carrier provider in order to unlock it and change the status to "yes", so, you could unlock your bootloader without any troubles in the process
Official Sony says you need to be in 4.4.2 or higher build number version, it's not stated you need to be in .37 build number.
Note: 4.4.2 (is precisely .37 build number, but, still .21 or higher works fine with the unlocking).
Regards!
i know its a bit turn off the topic, but while im still here let me ask - Does anyone know is Lolipop gonna come out for M2 or not?
There have been many different statements about this so id like to know once for all, is it or not?

No. It ain't confirmed yet. In some point might show up for our device. But right now there's no confirmation. Just OmniROM, CyanogenMod 12 and FXP AOSP.
If your bootloader unlock allowed says no. Then there is nothing you can do to unlock it. Not even network unlocking your phone will change that. To get bootloader unlock allowed yes buy sim free unlocked device. Most carriers lock down bootloaders hope this answers your questions

But ive hear many times people are "decoding" their phones in order to get SIM free device, why cant i do it?
And is there a way to root my device without unlocking bootloader?
To root you need to search on here plenty of easy to follow tutorials on how to root for locked and unlocked bootloaders.

Under what assumptions you say that? Topics before some guy said that he unlocked its device changing the status of its SIMLock with some code to unlock it. The carrier locks down your phone via SIM, but it doesn't mean you can't unlock it forever. If you "free" it, the problem must be solved. The guy I'm talkin' about, unlock two devices using the same method I'm sayin' here, and the two of them went fine. So, just try. The carrier shouldn't show any troubles in order to disable the SIMLock, it's your right, in fact.

601SO XZ Bootloader Locked

Hello. I have a Softbank 601SO Xperia XZ (which I sim unlocked as recently I changed to Y Mobile) and am wondering what I am able to do with this device. I can't change the status from "Bootloader unlock allowed: No" and when trying to downgrade Android from 7.0 to 6.0 by flashing it, it seemed to be softbricked so I had to factory reset it using Xperia Companion (and it reset it back to 7.0). Does anyone have any experience rooting this phone with the bootloader locked or was anyone able to change the unlockable status to Yes?
Thanks!

### There is no way, because Bootloader unlock allowed is no. ###

I see, I thought that some people have rooted their phones successfully without unlocking the bootloader. I've also seen some people saying they successfully changed the unlockable bootloader status from no to yes by sim unlocking or downgrading their OS. Maybe these are rare cases...

Ya may be, after Marshmallow update you need to root by flashing zip Su/magisk and for that recovery is required.
Yeah, if it can't be brought back to a previous version it's probably not going to work...it's sort of annoying having a phone that belongs to you and is carrier locked even though you no longer have any connection with that carrier!
