Potential exploit to gain root? - Xperia Z2 General

Just read about this kernel vulnerability, which got me curious whether this can be exploited to gain root on the Z2.

That's the first thing I thought of when I read about it, too

[Q] Moto making DX unrootable with new gingerbread update?

http://www.gottabemobile.com/2011/0...oid-x-gingerbread-upgrade-to-prevent-rooting/
Is this article true? Has anybody installed the latest official update and not been able to gain root access? If so, then I had better root my phone already before this gets rolled out.
not true. it's already been rooted. it's called GingerBreak.
^ what he said
It would be near impossible to prevent root access.
Sent from my Xoom the way it should be, rooted and with SD card.
There are so many bits of untrue information in that article it's not even funny.
1. It is rootable.
2. It is not a silent update.
3. The bootloader doesn't affect superuser access (root).
Amongst other things... I won't be looking to that site for any real info in the future.

Question on stock root

I got my S4 on release day and I have been really reluctant to root because I am happy with the way the phone is. But now I am tempted to root for 2 reasons. I want to be able to use every app in the multi window view and to be able to move stuff to the SD card.
So my question is....If i just root my phone but dont put and rom or recovery on it what would I need to do if Android or Samsung released an update? The update would not work if I was rooted correct? Can someone link me on the process I would need to do to be able to install such an update?
I believe there are root method which allows OTAs but you ll loose the root and you might need to re root again. If the root doesnt support OTAs then you will have to flahs stock firmware then update then root again.

Ok so for example if I followed QB Kings video in the Android Development Forum on rooting my S4 do you know if that root would allow for OTA's? I going back in forth in my head on if I should root or not. On one hand I would want these extra features I mentioned but on the other hand is it worth the hassle of dealing with the OTA update process.
Based on my limited knowledge, it is possible that if you take OTA, you may not be able to root again (if the OTA patches that root exploit). Hopefully the awesome Devs on here will be able to find another exploit, but it is possible that you may not be able to re-root.

Sorry no idea about that method. You should ask in that thread you might will get proper info. And BTW OTA for now are provided fast but as everybody knows it takes a while for Samsung to roll out important OTAs so you might as well root than sit hoping for OTA while missing all the modding action.

Very good point in not waiting around for an OTA...they do take long as hell to push out....and I will ask in the QB King thread to see how OTAs work with that root process...Thanks so much

Simpler Root Method

I just got my Z3c over the weekend, and since it was working perfectly on AT&T with LP 5.0.2 I was reluctant to do the whole downgrade/unock/relock/root/flash/upgrade/etc. root method.
Fortunately the latest version of Kingroot will root the phone with OTA Lollipop upgrade working and unlocked bootloader. I have 23.1.A.1.28 rooted without even having to enable ADB or do anything but install and run the Kingroot app.
EDIT: Editing here by request on this thread. There is another thread on this forum dealing with Kingroot in detail. Some suggest that the Kinguser app transmits the phone's IMEI and this introduces some risk. For me, I managed to get rid of the Kinguser app and install SuperSU instead. My phone works fine, rooted, with SuperSU (which was installed via recovery/flash method). I have no comment about how risky Kinguser app is, whether anyone is trying to steal something from you, or what your risk level might be with Kingroot method. Buyer beware.
I would say, if Kingroot can do this without the downgrade/unlock/relock/upgrade method then so can non-KR devs.
Does it work with a locked bootloader?
We already have a thread about Kingroot: http://forum.xda-developers.com/z3-compact/general/kingroot-4-0-t3105593
It's not being stickied because it's a very shade rooting method, very little is known about how it works and what more it does behind the scenes except for rooting. And Kinguser cannot be replaced by SuperSU by any normal, conventional means.
Yes, it worked on my phone with a locked bootloader.
Sorry for the confusion. I didn't realize Kingroot was such a bad thing. It's also very difficult to remove.
FWIW what I did to get rid of Kingroot and the Kinguser app (which is the real beast to remove) is after rooting with KR, I installed the dual recovery and then flashed the pre-rooted LP from TWRP. That totally eliminated the KR and etc. so if anyone has taken my potentially bad advice and rooted with KR, that's how to undo and retain root with SuperSU. I still think it is easier/simpler than the "tried and true" method of rooting for those who have already upgraded to LP/5.0.2.

IMHO someone should update the sticky threads. This is a much simpler method to get rooted LP on your Z3c. Just upgrade as usual and then root with Kingroot. Couldn't be easier.

Its not so tricky to root with giefroot. Just downgrade, root install dualrecovery and flash pre rooted lollipop. Thats all. Personal i dont trust kingroot. Nobody know how they do the root and there are always discussion about some data sending to servers. But its everyone choice

followed the method in the first link, worked perfectly.
Super-sume on the play store does that with one click to remove kingroot
1) I suggest you change the title or just close this thread
2) I suggest you install a clean new stock firmware through Flashtool and root it via Giefroot ONLY (I know downgrading is boring and a bit harder, but that is still the safest method)
Kingroot is the simplest method, maybe not the most safe.
Giefroot is the longest, maybe the most safe.
Both of them have the same effect, root the phone.
No need to close the thread, I don't care Chinese developers need my IMEI to root my phone..
So if you agree with this idea, where is the problem? We are free to choose if we are informed to that.

The right thread with the right title and the right OP is already here:

That's why I suggested they close this one.

I can't see any information about risks inside the OP of this thread and that's the only post a noob usually reads!
Please search the meaning of the verb "to suggest": it's not imperative and gives freedom of choice.
In this case, this one already exists :

[ROOT ANDROID][2.x-5.0] KINGROOT: The One-Click Root Tool for Almost All Devices
Maybe, I suggest to close all double threads(or seems to be)... I suggest to all noob peoples to keep all questions for themselves... Great for a forum ! ?
Don't feel assaulted, just I think to ask a same question differently gives another answers, it depends who is asking and the point of view.
But you are right for the risks with IMEI.
We don't know if there is a risk or not, but it's just my opinion. ?
I think to help and share experiences are the good way.

Rooted with kingroot, installed dual recovery and removed kingroot/kinguser with super-sume app (on play store).
All these steps with locked bootloader and last LP firmware

Idea for a root exploit

Hi everybody,
I'm asking myself why can't we exploit the stagefright bug to earn root and then install supersu and recovery on the smartphone?! If you agree with this, just tag some developers, I know that it's very dangerous but if we get root then make a pre-rooted 32.0.a.6.152 which correct stagefright bug then we'll be OK..
http://www.xda-developers.com/stagefright-explained-the-exploit-that-changed-android/
Stagefright itself isn't able to exploit to gain root. AFAIR it only gains system user, so another exploit would have to be used to root.
Tag devs!!
New root exploit using Chrome discovered!!!

Root/Unlock then upgrade to Marshmallow

I'm on KitKat (4.4.2) stock. KOT49H.G900VVRU1ANCG is the build according to about phone.
My phone is rooted and that's it. I never upgraded because of fear of slow-downs and lack of root, but it's about time.
Is it possible to unlock the bootloader and then upgrade to marshmallow and get root? I keep seeing people saying there's a Lollipop root method but no Marshmallow method. But if the bootloader is unlocked doesn't that make it possible to root Marshmallow too? I checked and I have the 15XXXXX CID.
So any ideas how to best go about this?
I just want the simplest experience. No crazy ROMs or bug, nothing I have to keep updating. Just a smoother running phone than I have on my dated KitKat.

Thanks for the reply, but as you can see I've looked at the threads (even mentioned my CID). My concern is that, as I mentioned, "I keep seeing people saying there's a Lollipop root method but no Marshmallow method."
Since that part isn't clear to me, I hoped someone would clear it up.

Go to the unlock thread that's located in the Android Development section. There's a method for unlocking to get to MM.....if you read a little bit deeper in the threads that ideveraux had mentioned if you have the 11 CID you cannot be rooted on MM because it uses a different kernel. That said, users with the 15 CID can be rooted on MM AFTER they've unlocked their Bootloader. Again, go to the unlock thread and read up
