You can have root without unlocked bootloader
but It makes me wonder why you would revert back to locked?
just wait for someone to make a ROM / nandroid and flash the new file lol.
OTA is for people who aren't used to fooling with there device
apparently i tried rooting but i cant root without unlocking bootloader, only after i unlocked the bootloader i manage to get root
so it is advisable to just keep my unlock bootloader and flash new roms using Flashtool?

If you want a practically guaranteed method of rooting, yes that would be easiest. FTFs only come out like 1-2 weeks at most after the update is sent out anyway

Well the Link is broken but if you root your phone VIA Exploits, aka bin4ry root , then you will not lose your DRM keys, the only ways to lose your DRM Keys , is to Unlock your bootloader, if this method includes installing a Previous version kernel (elf file) then yes you will have to unlock youur bootloader
there is a way to back up your TA partition , but you will have to search though the development section
You only loose DRM when you unlock bootloader.
You cant loose it in any other way.

so, to root my phone with the method i posted, i have to flash my kernel back to an old version, then i must root and then i must flash back the new kernel, so i cant loose my drm keys with this method?
here is the link to the root method:

Well to flash any Kernel you must have a unlocked bootloader (not sure if it matters if its a FTF file kernel)
unlocking your bootloader removes your DRM keys, you can RELOCK your bootloader but you will not have your DRM keys unless you backed them up
(like said unlocking your bootloader can wipe your TA partition which contains the DRM keys)
EDIT - it says in big and blue , FOR UNLOCKED AND LOCKED BOOTLOADERS

my bootloader is already unlocked from factory, so i can use this method without loosing my drm keys, and when i install a custom android version, i keep my drm keys too?

well tell me if bravia engnine works (images look clearer , brigher, blah) , Bravia Engine depends on DRM keys, now when a device is unlocked from factory then im not sure if it has DRM keys
and even if your bootloader is locked then ROOTING VIA that method should work either way, drm keys kept too

How come your bootloader was already unlocked by factory?
It is impossible.
Are you sure you see "bootloader unlocked: yes"? Not "booloader unlock allowed: yes"?

not can you use it , DOES it work?
my XS when i bought it said Rooting status Bootloader unlocked = yes, although saying that bootloader was not unlocked
unlocking my bootloader means, that i have root rights or?
in my service menu is bootloader unlock allowed yes
so, i want the information, i want to keep my DRM Keys, so are they lost when i flash a new kernel version? because i have to flash back the kernel to root my phone and then i can flash back the new kernel, so do i keep my DRM keys or they lost now?

rooting your devices keeps your bootloader locked, also drm keys
flashing a stock kernel does not need unlock bootloader
flashing custom kernel will need unlock bootloader
Sent from my LT26i using XDA Premium 4 mobile app
Stock kernels are signed by sony, and locked bootloader can boot signed kernels.
That means you can flash any stock kernel anytime with locked bl.
Unlocked bl is required to flash custom kernels, and so that custom kernel ARE not signed by sony.

So much work...
And I wish it would include links.
I really hope there will be a one-click root for 4.4.
It's weird all phones from the competition are easily rootable but someone 4.3 on Sony is so complex.

They've closed alot of the bugs that were being used for the previous root methods.
IF you don't care about your data, what you CAN do is to revert to an older FTF, root, backup your TA partition, then go from there... it's a pain... but it works.

Seems much easier (no bootloader unlocking necessary) so I'm trying to figure out why you'd have to do everything listed in the other thread. Any insight?

if u want your phone to be stuck in bootloop, go ahead with that method, else you follow the method which i posted. it's a long procedure, but it works!

I don't understand why someone would post bad directions like that. Also they are very similar to Doomlord's own instructions for rooting. He says to flash an old exploitable kernel and then run his exploit and then flash back.
Anyways, your method says to downgrade to .67 firmware, and I can't find that anywhere. Can I downgrade to .423 firmware and use Doomlord's root method instead? Should be the same results, right?
Also, is step 8 necessary? Do I have to flash back stock recovery or can I keep CWM?
And finally, using this method, how will we keep root when 4.4 finally arrives?

Thanks, It worked without any problem.
I also wouldn't take the risk to flash the Kernel of .423 over the .67 firmware.
Yes they are both Android JB 4.2. But you never know.
About 4.4, we will have to wait what will be the available methods.

yeah. that kernel method worked for previous firmware. now it won't work. and yeah you can downgrade to any rootable firmware. u are doing this just to backup TA so that you can lock BL. you can keep that advanced kernel. but you wont get OTA updates, better to flash stock kernel and lock your BL. when 4.4 arrives, if no rooting kit is available, you've to unlock BL, install advanced stock kernel which has custom recovery and install SU and flash back stock kernel and lock your BL
After you've rooted, but before you actually unlock your bootloader... if you install the dual boot recovery, you can make a backup of your TA partition information via TWRP as well as by using the other method... (do both to ensure you can revert)...
And then after you unlock your boot loader save ANOTHER TA backup... name them so you know which is which so you can re-lock your TA if you choose if you're running a stock kernel/rom and want the DRM keys back... but that way you don't have to go through the pain for unlocking each time...

Well I ended up not even needing to unlock the bootloader for my goal, which was simply stock + root on .101.
http://forum.xda-developers.com/showpost.php?p=52411661&postcount=23
Only had one small issue with the flashed zip/stripped FTF messing up the XZDualRecovery settings, but deleting xzdr.prop and rebooting fixed it.
When i was searching for, i really thought i was being crazy.
so many devices with a single click to root
I cant wait to start theming my ZL, Some mockups cooking here to new skins, but can't test without that root.
well, Did that steps worked well?

if u go with method, u have to download those stripped files every time when new firmware arrives. which is kinda boring to download those huge files. whereas in that unlocking BL method, u download only kernels with recovery which is just 15 to 20MB
I would like to ask if there is a point in waiting for a root method with Locked Bootloader or not.
Thanx a lot!

With unlock boot loader and there is method to save to DRM keys. Whenever you want to relock, relock your boot loader with DRM keys. And even with unlock boot loader all functions are running properly.

No point...the stock kernel got dm-verity (verified boot) any changes made to it won't let you boot...and there is no way around it, the only way to root is with a custom kernel....
If you use iovyroot you can temp root on Lollipop and back up your TA, once you're on a custom rom you can also flash your drm keys (not just emulate), so you're all good...
People that can't unlock are out of luck...

You misunderstood what iovyroot does, it's a temporary root that uses an exploit found on certain versions of Lollipop (so it won't work on MM . 224 or .253) you need to downgrade to a Lollipop firmware that is listed for your device, then you can root temporally just so you can backup your TA so you won't lose your drm keys forever once you unlock your bootloader...
This here will also explain in all details why you can't root when dm-verity is in place
You will never have full root because of dm-verity without unlocking your bootloader for the reasons explained above....
You can use this tool to fully reactivate your drm keys if you backup your TA partition before unlocking....
Hope that is a bit more clear for you now

Thank you for your answer and links!
I posted the previous answer because i had read this guide that says:
"2. BACKUP YOUR DRM KEYS
There is a tool called iovyroot, with which you can backup your DRM keys from an unrooted phone, but at the time of the writing it doesn't support the latest firmware (.224). It does support a lot of older firmwares so it may be useful to not upgrade your phone before checking up this tool."
How likely is it that in the future there will be a way to root this phone for boot loaders that can't be unlocked? No chance?
Uhhh...not exactly the same but with more or less the same effect. http://forum.xda-developers.com/z5-...ck-root-xperia-z5-premium-sony-stock-t3335974

No chance...the only way to root is to unlock your bootloader...
This is because of dm-verity this link will explain it all...
That's why you can temporally root on some older (and new ones with new found exploit dirtycow) firmwares with known unpatched exploits (as seen in the link in the above post) but you will lose root upon reboot

There is dirtycow based TA backup tool. Backup your TA, unlock bootloader, flash and root all you want, if you need to reset phone, flash your TA partition, reflash firmware and no traces of root will be found.
What will happen if I root the phone and the update for Nougat arrives?
Will I be able to update and keep root, or do I have to recover phone to original state and then update, root,etc. Thanks!
