Is it likely root will be found without unlocked bootloader? - Xperia Z5 Premium Q&A, Help & Troubleshooting

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!

[Q] Lost root from efrants root without wiping (4.1.2) to Android 4.2 update (solved)

Hello all,
I already searched the forum but I did not found any good answer.
1. In the past I've succesfully applied root access without unlocking the bootloader while still beeing on Android 4.1.x from this guide:
http://forum.xda-developers.com/showthread.php?t=1894717
2. Now I've got a 4.2 OTA update. Before applying it I used Voodoo OTA rootkeeper to keep a backup of su.
3. Restored su with Voodoo OTA rootkeeper
The result is that I have again root access from shell but when I want to use Apps which require root I always get failures and even no confirmation dialog.
How do I get superuser working (fully root) like before?
Thanks,
therealmarv

How should I flash that without having CWM? I think I need a manual repair :/
Is your bootloader locked?
If not...use my guide (in sig or stickied) to back up data before unlocking...
If so... "fastboot boot recovery.img" and flash the file.
The recovery is only being booted into...not written to the phone; so you'd still be stock rooted.
How in the world you not have a unlocked bootloader when you rooted before..
That aside, do remember to keep the bootloader unlocked next time..

The same sort of exploit that was used in ICS was eventually found for 4.1.1 that allowed root without unlocking.

What i mean is how can they not unlock the bootloader after rooting..
I did not unlocked bootloader because I thought it is not necessary (and I also thought it will affect OTA updates). So just to get it right: I can make a backup of my phone, root it, unlock bootloader and recover the backup afterwards so that no data is lost?
Ok I solved my issue (having su access via adb and locked bootloader) with this thread:
http://forum.xda-developers.com/showpost.php?p=27085483&postcount=141
1. I unlocked the bootloader with the link above
2. flashed CWM with fastboot
3. flashed SuperSU CWM ZIP for getting root again
So I now have fully root, unlocked bootloader and cwm great.

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

if you have backed up your ta partition before, then proceed with the following steps
unlock bootloader
flash any xperia zl kernel which has custom recovery like CWM in it. for example, this one ==> http://forum.xda-developers.com/showthread.php?t=2191264 (though it's meant for older firmware, the recovery works but the phone wont boot to system)
enter into recovery and flash the supersu zip
then switch off the phone in custom recovery itself. (because the phone wont boot to system)
then flash back stock kernel and you have root :good:

u can get root access now but u have to unlock your bootloader. and you can't relock it unless you have the TA partition backup.
to get it, you have to flash back old firmware to gain root. backup TA partition so that you can relock bootloader. and in the future you dont' have to downgrade again to root

yeah. just flash an older rootable firmware(10.3.A.0.423) using flashtool. root it using doomlord's rooting kit. take a backup of TA partition using devshaft's backup-ta kit. this back up of TA is just to relock your bootloader whenever you unlock it because unlocking BL voids warranty. but the backup of TA partition must be taken in locked BL condition. flash nut's dual recovery. now follow the steps in the link posted above and upgrade to 4.4.2. this method doesn't need your BL to be unlocked.
there is another easy method which requires unlocking BL. but you can relock it as if you never unlocked. i prefer this method. the link is posted below.

[Q] Rooting

Hello.
At the moment I am using stock lollipop .270.
How do I root it in order to backup the TA partition ?
Probably you have to flash KK v108 with Flashtool, root that and flash an already rooted+recovery 270 that are in the general section of the forum.
Or check around general forum if you can root without going back (been out of the loop with rooting procedures). Something like this thread http://forum.xda-developers.com/showthread.php?t=3140241
So if I use Flashtool I guess I have to onlock bootloader. Wouldn't that destroy the TA partition ? I want to backup it before I begin modifing anything.

I rooted just a few days ago while on the 270 uk firmware. Unlock bootloader first then i auto rooted with chinese Kingroot app http://androidxda.com/download-kingroot-application . After this i follwed ( http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html ) this guide to remove kingroot and install super su. After this i used ( http://nut.xperia-files.com/ ) Th locked dual recovery from here which installed the recovery to the phone. Next step is here https://www.androidfilehost.com/?fid=23991606952609257 . Once you flash this prerooted firmware you are fully rooted. good luck i hope this isnt too confusing.
Note iff you do not unlock bootloader the kingroot app will not be able to root the phone. bootloader unlock is the first step.

For flashing a ftf via flashtool, You don't need to unlock bootloader. You could also try the link from My signature to root, it worked fine for Me on locked bootloader.

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."
