[HELP] About rooting on locked bootloader - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

I found a file in a japan forum about rooting Xperia Z4. I tried it but failed. There may be a member here who can edit it so it can be applied to do the rooting. I do not really understand Android. I hope somebody wants to try the file I will upload below. thanks.

Read all of the forums for this POS phone and you will learn you cannot root it with a locked boot loader. If you could, there would be an article in big flashing lights on XDA.

I found an option to allow unlock bootloader in developer options (OEM unlocking), you can try this to unlock bootloader

If you look in v android development there is an unsecure kernel, but this is for older firmware, maybe it works
Edit: you must unlock bootloader for custom kernel, i do not think bin4ry method works for newer firmwares

Thanks so much for your quick responses.
So right now, we have no root access without unlocking the bootloader.
Hopefully the genius developers will come up with something soon. A little bothered by the bloatware from my provider.
Thanks guys,

Hi funiewski,
I have tried rooting by flashing that kernel but I don't seems to get root when I check with the root checker app. Would you be able to advise on this? I would have posted in that thread but apparently I don't have enough post count.

Singtel hah? Hahaha ask Palmer clear for you lor.
Serious: I'm getting a V soon and is the bloatware that bad?
EDIT: You can clear bloatware by flashing an international version of the firmware.

There may be a way to root without unlocked bootloader
Try this well-known way of rooting Xperia AX in Japan.
I guess it's also possible for V to root.
1. Here is a Xperia VL's old rom and you can flash this kernel.sin and system.sin with V's loader.sin.
I can't post the link, but you can find it in uploaded.net. The ID is 3gvvv3w6.
2. Then, Root.
3. Create /data/local.prop (ro.kernel.qemu=1).
4. Flash V's system.sin without wiping.
5. Replace ric, install Busybox and Superuser.
6. Flash V's kernel.sin without wiping.
7. Do Factory data reset to easily delete unnecessary apps.

after downgrade you can also use CWM to flashing anything you like. Flashing XperimenT 1.7.1 is the best way after you root your device.

[Q] How to root Sony Xperia Z latest 4.3 update?

Hey guys, so I updated my phone here and I'm trying to root the phone. I have search the web for question but none. So, I decided to do the old method way. Can I use the 4.2.2 (2.67).tft flash it to the phone and root it. And then flash back to the 4.3 (.569).tft. Thanks. Also please provide me with some links for the root.

Please use the search guys, this has been discussed in many threads all over here and the general section ever since 4.3 was released.
Currently, the only way to root after you have already flashed 4.3 is to unlock your bootloader and flash DooMLoRD's advanced stock kernel.
That's it, until somebody finds a way to root with a locked bootloader and that doesn't mean you have to post asking for it. Once someone has a breakthrough, they will publish their work here for certain.

If your bootloader is unlocked you can try this. It worked for me.

So, basically exactly what I already said. Flash DooMLoRD's advanced stock kernel and flash a superuser zip.
No need to give page views to yet another website that just reproduces guides/work of XDA members.

I'm not sure why you revived this thread that is several months old to post that.
Firstly, it's just a reproduction of information from a couple of DooMLoRD's threads from here and here on XDA.
Secondly, it directly links to his files, which is a no no.
Thirdly, there are also direct links in that article to unofficially hosted versions of Androxyde's Flashtool, which is also not polite.
Please don't push page views to places that do things like that. Thanks.

[Q] Xperia Z1 C6903 Vodaphone, Bootloader unlock : not allowed. How to ?

Dear All,
First i thank you for you huge contribution to human needs in this planet ! You Rock dear community.
I'm more a reader than a contributor in most forums, i usually find the answers only by searching other people posts, but this time i couldn't find an answer .
I have an Xperia Z1 C6903, Vodaphone (i guess from spain), running Kitkat 4.4.2 with latest firmware 14.3.A.0.757.
I was trying to root it, i red practically all the methods here in the forums & elsewhere, and there was always one step that i couldn't bypass : UNLOCKING THE BOOTLOADER.
I took my code from Sony website, i tried many methods in vain. In my Phone it shows of course : Bootloader unlocking allowed : NO
My question is very simple : Is there on earth (even on other planets i can take the trip) any method to unlock my bootloader ?
Thanking you All in advance, and apologizing if this question is already answered in another topic, i really couldn't find it.
Awaiting your Help Dear Community.
Best Regards,
NO! There is no way to unlock it, there is no way around. Sony will generate the Code from your IMEI anyway but if will not work. Do not even try on Earth to find a way because there is not.
There is absolutely no need to unlock the bootloader in order to root.
Which is good news for you because you cannot unlock anyway.
In order to get root on the latest firmware then you just need to follow the link in my signature

@gregbradley, excuse my question, but have you done this before on unlocked Z1 ? i mean will have full access to my phone ? (Install Super user, Titanium backup ... etc etc )
Thnaks Again.
once or twice
Just follow the 3 steps in the link
There is no need to unlock the bootloader, no need to backup TA partition (You only do that id you are unlocking the bootloader anyway), no need to use any dodgy rooting methods (Like Vroot etc)
Flash a 534 FTF
Install dual recovery
Flash a pre rooted rom
Takes about 10 minutes

Hello Again,
Done ! The method worked for me, my Z1 is fully rooted now even with my locked bootloader ! Thanks again
Only, and for those reading this post, specially Xperia Z1 C6903 owners, for step one you have to pick a specific FTF file and not any FTF ending with 534, The only one working (and gaining you Root access later on the process) is FW 14.1.G.1.534
Although you are on a recent FW, don't worry, after accomplishing the other steps, you will be back to the latest one.
N.B i tried many of the FTF ending with 534, but it didn't work except for FW 14.1.G.1.534
Cheers.

It's been explained in some posts by our fellow devs in some of the threads - the answer is: no root without UB, because the kernel has a so-called 'verity check', which detects any system modifications and panics if it finds one, and for this to be overcome, there are already some kernels which bypass this check, but as you know, you can't install a custom kernel without unlocking the bootloader.
However, I saw some hopeful post about M, something about an exploit being available for half-root, enough to backup your TA and unlock bootloader with the option of re-locking it afterwards without losing your DRM keys.
