With am unlocked bootloader.... Flash an insecure kernel.
Having an unlocked bootloader is the easiest way to root, but not always the best....

Thank you for the answer. I was looking for such a kernel and I did not find any, maybe you can give me a link please. So after I flash that kernel, with Flashtool, what do I do next?
Look in the dev section. There are loads of them. Just flash it. You will have root

Ok, I looked, I found AndroPlusKernel.
But someone in that thread asked if he needs root to flash that kernel.
The reply was : YES.
So which is it? I want to root the phone, If I flash that how is my phone rooted, how can I flash a custom recovery?
You do not need root to flash a custom kernel, you need an unlocked bootloader.
On Xperia devices generally a custom recovery is in the custom kernel you flash.

Ok, I have installed a kernel with TWRP included, all good until I installed Xposed for Lollipop, that alpha version, now everytime I restart the phone I get a bootloop. The only fix is reset to factory settings, and after that the same, every time I reboot the phone I get a bootloop.
The only solution is to reflash a ftf ?
Well, thanks for nothing, I will fix it myself.

You install an alpha version and it does not work and you blame me.
Please take some time to consider what xda is about before you start blaming others because you can't find the fix to it.

Hello !
I recently bought a used Z3 6603, and wanted to update it to lollipop.
But it seems it has a unlocked bootloader (according to service menu) and when i recieved it, it was factory reset, but some 3rd party apps were still installed.
One of them Super SU, so it was rooted.
I was told that i could update the firmware if i just used the Full Uninstall feature in Super Su, so i did that.
I still can't update using sony companion, becouse it knows the software is not the original one.
And i cant reinstall super su, its saying that there is no SU binary installed and the program cant install it.
I have flashed phones before, but it was really a long time ago, so im asking for some help to fix this.
Its running 4.4.4 build 23.0.1.A.5.77 and stock rom i think.
Please tell me what to do, and what info you might need !
I want to have the phone in lollipop, but everything stock, no root, no bootloader etc.
And somewhere I read something about DRM keys. Please help me with fixing that aswell thank you.

Your DRM keys are lost forever.

Ok, so they are lost even if I use the first backup that was made by the person I bought it from ?
DRM=Hardcoded=Once unlocked, always DRM free, even if you use the recovery image ?
And the rest of the questions, what am I supposed to do to get stock lollipop?
In the matter of fact it does not matter if its unlocked or locked, I just want legit lollipop, with the possibility to update regularly. (But if root is possible at the same, it can still be rooted)
Thanks for your reply !
You need the TA backup. Not system backup.
And careful not to restore some other TA.
If the previous owner backed up TA, good. If not, no chance to recover them.
Download your specific firmware in ftf format and flash it with Flashtool.
Make a clean install.
You cannot recieve OTA with an unlocked bootloader, only if you relock, but there is no point in doing that if the DRM keys are lost.
So, from where you stand, keep it rooted and unlocked, because you can do much more with it : Custom ROM' s [at the moment stock is best]...custom kernels with recovery...mods...etc.
After you flash the ftf, flash via adb a custom kernel with recovery and from recovery flash SuperSU update, as a flashable zip, that will root the phone and install SuperSU.Search also for busybox flashable zip.

Ok, I will try that then, but if I use flashtool to update to lollipop, will I still be able to root easy, or should I reinstall 4.4.4 clean, then root, fix recovery kernel and everything, and then lollipop or what goes first?
Does flash/kernel etc affect the fact that it has an unlocked bootloader ? do i need to do anything with that, or do it stay unlocked?

If you have unlocked the bootloader it is always a trivial matter to root.
Just flash an insecure kernel.
If one does not exist use [NUT]'s online kernel builder to make one with recovery incorporated in it. Its very straightforward and an automated process.
So, update using flashtool, flash your custom kernel, and you have root and recovery.

1. Sorry for my noobish question, but define insecure kernel?
2. Did I get it right? I read about ppl downgrading their phones to 4.4.4 and then installing stuff. And for me it does not matter wich version it is, becouse the unlocked bootloader makes it easy to flash, even what version you are running?

1) a rooted kernel.
2) If you have unlocked there is no need to follow any of the locked bootloader guides, they are a waste of your time. One of the points point of unlocking the phone is to easily get root. You just flash a custom kernel to gain root.
If you have a locked bootloader then you have to go through all the fuss of downgrading etc etc.... but with an unlocked bootloader its so easy and straightforward

Good luck.
Hello there,
have been trying to root my new xperia z3 for 3 weekends now with no luck.
My bootloader has been unlocked through sony website, then relocked and unlocked many times using flashtool.
Looks like all the recoveries (doomlord, twrp) I could find work only on 4.4.4. Then I use flashtool to flash lollipop 5.1.1 23.4.A.1.200 and either wipe and loose the root or don't wipe all and enter a bootloop.
Flashing those recovery kernels straight on lollipop make the phone enter bootloop.
Are you guys able to root those Z3 under 5.1.1 ?
thank you
Sure shot easy way is flash kitkat firmware and use giefroot or flash 5.0 firmware and use kingroot.
Mate, you have to flash a prerooted version of 5.1.1 you can't just flash a stock rom and expect to stay rooted.
Downgrade to Kitkat then root and install a custom recovery. Then you download 5.1.1, Super Su and a custom recovery, create a pre rooted flashable zip with PRFcreator . Then flash it in your custom recovery and you're done. Rooted 5.1.1 with a custom recovery ready to rock.
Kingroot isn't recommendable, your IMEI is sent to China. Downgrade to 4.4, root with giefieroot, upgrade with pre-rooted ROM.
Btw: did you make a backup of your TA partition before unlocking bootloader?
Thanks a lot for your answer guys.
Am unusually struggling with this device.

Have already downgraded to kitkat, installed custom recovery and rooted. But the 5.1.1 stock flash indeed wipe everything.
Haven't found yet a custom recovery for 5.1.1 that doesn't make the phone enter a bootloop. Would you happen to have a link ?
I'll give a look to that PRFcreator, didn't know about it.

This is what I read about kingroot and haven't found any other way to root a 5.1.1 stock.
Where could I find a pre-rooter ROM then ? My wish was to be stock and rooted to be able to use apps like titanium backup and adblockers. Used to try custom roms every other day on my old SGS but today I'd be happy with something that just works.
Did not make any backup before unlocking but looked like flashtool was able to relock the device. Am I right guessing I didn't loose my DRM keys then ?
Thanks again for your answers.
Edit: looks like am missing sthg, what's the point in rooting a kitkat to upgrade with a pre-rooted lollipop right after ?
After KitKat root you get a Lollipop pre-rooted image and flash it: http://forum.xda-developers.com/z3/general/d6603-5-0-2-flashable-stock-23-1-0-690-t3056361
Here are the steps: http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
I hope you made a TA backup before unlocking your bootloader, otherwise you have lost your DRM keys forever.
Anyway, if your bootloader is now locked, follow the guide that Licaon_Kter linked in the above post.
The exploit that lets us root our Z3 only works on Kitkat, so downgrade first, run the exploit to obtain root, and install recovery.
You will then have stock, rooted, KitKat.
To get to 5.1.1, you will then need to either create your own pre rooted firmware, or download one that someone has kindly posted on here.
If you want to learn how to do it, read this --> Create your own pre rooted firmware with PRF Creator
PRF Creator will create a zip file that can be flashed from recovery, so once you have recovery installed, it's dead easy.
That will get you where you want to be.
However . . . and there's always a however lol . . .
. . . if you still have an unlocked bootloader, it is much simpler from wherever you are.
Find any custom rom that has recovery built in, and almost all do, then fastboot the kernel only, the boot.img.
Reboot your device and enter recovery.
Install your pre rooted firmware that you have either created with PRF Creator, or downloaded from here.
Job done.
My personal advice is read, read, and then read some more.
It can be very complicated, but you'll get the hang of it.

I still have an unlocked bootloader since flashtool can lock and unlock it in a matter of a second.
Went back again in KK rooted with twrp recovery.
Wiped data, cache, dalvik.
Flashed D6603_23.4.A.1.232_Customized_US_SuperSU_XZDR2.8.2 1 from the link above and ... CWM recovery report install from sdcard completed after 1s and nothing more. Am still booting in KK after that.
This didn't work for me. Am losing it now with this phone.
Am I missing sthg ? Any advice ?
Can't use PRFCreator, am under mac os...
Thanks to all for your help

I appreciate your still trying to help me.
I do use flashtool and am able to root a Kitkat 23.0.A.2.93, so I don't see the point in using giefroot unless it could root a lollipop.
I have read thoroughly and downloaded pre-rooted lollipop stock roms from the link you provided.
Once under KK, rooted, with all settings set properly (debug, security, etc...), and all caches/dalvik/data wiped, the CMW recovery just don't flash those lollipop roms. After just one sec, it says install completed but then the device still boot under KK.
TWRP doesn't even intall, so am wondering if this is even possible to get a TWRP on stock rom.
Have tried all of those with bootloader unlocked and locked, or a mix like unlocked first to be able to root a KK, then relock to flash a stock prerooted 5.1.1 (as stated in the post) but then I get a device that doesn't even boot.
Tried dualrecovery too, flash the zip, and nothing.
I suspect all of you guys have used some sort of .bat windows utility to get through this.
Once again, thanks for your help and patience.

The point is to go from the BEGINing _again_: Flash stock KK, giefroot, XZ, pre-rooted LP
I have done it in Linux w/ locked bootloader and stock ROM, hence my pointers.
XZDualrecovery has TWRP 2.8.7.0. But, do take note that you use Volume Down to enter PhilzTouch Recovery and Volume Up to enter TWRP.

am sorry, can't find how to use giefroot on a mac.
read quite a few post of people saying that was not working for them.
Run the INSTALL.SH file in a console (just like they instruct you for the .BAT file for Windows), it detects OS and runs either adb for Linux or for Mac.
Well, like I said, it worked fine in Linux, I guess it should work on Mac, providing the device is detected ok beforehand and such. ( what does "adb devices" outputs with the phone connected ? )

Hello,
Excuse me for asking such question but I have never Boot Unlocked & Rooted any Sony smartphone so I'm confused here. I have only rooted LG and Samsung before without Unlocking the Boot as it was straight forward process. I have found this tutorial and everything is fine as I have got "Bootloader unlock allowed" in service information which confirms that I can root my Xperia. However when I visit the official website to get my unlock key it says that I need to be on software version 18.3.C.0.37 where my one is 18.6.A.0.175. Do I just use this official website to generate the unlock key and then use the flashtool to do it anyway ? I have use flashtool before but just for flashing the TFT file. Also after I unlock the bootloader how do I install custom recovery mode then install or back up the whole OS ?
If someone would help me I will appreciate your help. :good:
Thank You.
Ok, so right now you don't need to unlock bootloader to root M2 with 5.1.1. (At least not on 2306). Anyway, when you go to official website, they ask for your imei (after selecting your device). And then they give you the unlock code, they tell you how to unlock the BL with such code, with some SDK tools, but i prefer using flashtool since it does the job for me. So, after you open up flashtool, click on the icon that sais "BLU", it will ask you to select your device, you do so. After that it will ask for the unlock code, you put it in and click on unlock. After that it will do a procces, when finished, your BL will be unlocked.
I do gotta tell you, i've unlocked BL for 2 or 3 devices, all of the times everything goes right, exept once. After unlocking BL i ended with a bootloop. So for this case just turn off the phone, and flash any ftf. Bootloader will not re-lock after flashing.

Ok, thanks !
Also why do they say I need a software version 18.3.C.0.37 ? Could it be that their SDK tools require such version where Flashtool works on all of them ? Do you know how I can install custom recovery ? Do I still use CWM Recovery or something new and how can I flash new rom into it ? I have also heard something about emma when flashing rom ?

Sure no problem, about that i'm not sure, i've never had that android version issue before. For CWM you can get it here:
http://forum.xda-developers.com/xperia-m2/general/d2303-philz-touch-recovery-6-t3047492
Go to where it says "Download recovery" and download latest version (V0.7). Of course you have to be rooted in order to install. After you have root, enable usb debuging on your phone, and enable unkown sources just to be sure. Open the install.bat inside the file you just downloaded and follow the steps.
After you have CWM you can flash roms and other stuff.
so, I've rooted with kingroot and installed dual recovery, then downloaded cm 12
on philz, I used that "prepare for new rom"
and went I went to flash the zip...... it was corrupted.
and so, I downloaded the zip on my pc and tried to flash it with sideload, it didn't work.
so I thought that philz sideload wasn't working and tried to boot on twrp
but, when I turned the phone on again, I couldn't get into recovery.
I can get into flash mode just fine.
pls help :^(
also, I can't get it to show on fastboot devices :^(
If u want to use Cyanogenmod, then u have to unlock the bootloader or else u will get a softbrick, anyway u can recover your phone with flashtool or with pc companion, after re-install firmware then unlock bootloader but as you know, u will loose drm keys (bionz etc), for working Cyanogenmod u need a custom kernel aswell so unlocked bootloader is indeed

you can use flashtool and a stock firmware to get your phone unbricked
