Help rooting? - Xperia Z1 Q&A, Help & Troubleshooting

Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

Thanks for your help.
I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks

Figured out. Thanks

New to Sony, need to ask few Q before root/unlock BL/rom

Hi Sony users
Finally got my Sony Xperia Z1
specs:
C6903
basebans: 8974-xxxxx
kernel: 3.4.0
Build: 14.1.G.2.257
Serial: BH902xxxxxxx
I just tried chinese vroot and it doesnt work, found on another thread it's not yet supported for .257 firmware.
So wanted to check if I can flash another stock rom as this phone is bought from t-mobile and think it's branded
(under software info it says: TELEKOM-LTE_14.1.G.2.257)
Coming from HTC (had few of them) this is another world with different flashing tehniques, bootloader, flashing stock roms, recoveries..
What I would like to know, I need root, which is simpliest way to do it?
Flash another stock rom firmware like this one?
C6903 14.1.G.2.257 Central Europe 1276-4314_R2A
Via flashtool?
Thanks for any info...
Please read the guides.
Read the sticky threads here
http://forum.xda-developers.com/xperia-z1/development
http://forum.xda-developers.com/xperia-z1/general
and read this thread (This one tells you how to get root on .257)
http://forum.xda-developers.com/showthread.php?t=2505796
You don't need to read all the thread, just the first few posts with the info.
Thanks, I've been reading those since yesterday, but one question before I start to recheck.
Currently downloading unbranded central europe 1.534 and 2.257
want to flash 1.534 then root via VROOT and upgrade via OTA to latest, will that go ok or will I loose root?
Also, do I need to to TA backup before proceeding with anything via flash tool? Or is that only before going to custom roms/custom recovery?

Use kingo* root instead of Vroot (They will both work, but kingo gives you an English SUperSU not a Chinese one)
If you root and then OTA you will keep root.
You only need a TA backup if you unlock the bootloader, which you do not need to do to root, or install recovery or install stock based custom roms.
You only need to unlock the bootloader if you are going to install custom kernels or custom roms that need a custom kernel (AOSP,CM etc)
*You should be aware that kingo is currently not supported by XDA, I do believe that vroot is in the same situation. XDA do not believe this is for malicious reasons and kingo and vroot are working on new version which don't do this. However, the only way to root a Z1 is via one of these 2 programs.
Thanks for the tips, re-read needed topics and succesfully flashed .534 fw, rooted and now updating over OTA

Rooting .290 JB 4.3

Hello,
Coming from a Galaxy S2 flashing and rooting is not new to me but for me there are some questions for the Xperia Z1.
When i bought the Z1 it was on 4.2.2, and offcourse i wanted root the same day
After trying numerous times with Vroot i gave up.
After some more reading i read that i had to downgrade and then flash an older version, then root and flash teh correct version and so on.....(cant find the correct topics anymore )
After doing that my phone wasnt working properly and i connected with PC Companion and it gave me the update to .290 JB 4.3 and everything was fine except foor root.
Did some more reading and found the solution,
Now I'm reading that if you are on .290 4.3JB that root isnt possible(correct me if im wrong).
I want to share how i did it because for me it went very easy.The hardest part was getting the drivers installed correctly hhaha
First i unlocked the bootloader and then i flashed a CWM with root and recovery.
I followed the steps provided on this links.
http://techbeasts.com/2013/12/18/how-to-unlock-bootloader-of-sony-xperia-devices-guide/
http://techbeasts.com/2013/12/19/in...ng-latest-14-2-0-a-290-firmware-how-to-guide/
Al of this went so easy that i'm startin to wonder if its me who did it wrong and dont understand it or if you didnt know about it,
The only thing i forgot was a TA backup :angel:
to MODS....if its in the wrong section please replace it.
Actually it is the official way. Unlock -> CWM -> Root with CWM (Notification)
Rooting 4.3 isn't impossible, but morr difficult than on earlier versions. Google wanted to improve the security of android. Most of the ways which "make" the opportunity of rooting are malware-ways too.
You don't need to backup your TA partition with .290 and above, because the camera will work after the BL unlock.
The big question is if root for unlocked boot loaders will ever be available for 4.3! I really doubt it.
Sent from my C6903 using xda app-developers app
You mean Locked Bootloader, i think?
Question about CWM, does it function the same as it did with my S2? So, back-up and restore with CWM?

I have heard from @shem2409 that a partial root on LB for 290 (4.3) is possible, but I have not figured out how to do it yet. I think you can pull it off with the insecure ramdisk hack, but to install that, you need to install XZDualRecovery; to install XZDR, you need to be rooted; it's only possible to root 534 LB and when upgrading to 290 root is lost. So, it seems to be a chicken-and-egg problem to me at the moment. I think I must be missing something.

That's why I do not rooted mine phone yet. Partial root is not worth to do, full root is what we really need but still under testing and also Unlocked Bootloader is needed. Unlock bootloader we lose the DRM keys which we need if one day we want go back to stock and not lose warranty but to do that we have to Buckup TA. To Backup TA we need root, but I updated to 4.3 and I can't. It's to early to fully rooting 4.3. We have to wait. Developers are working on that and I hope a full root come without unlock bootloader. I hope so.

If you want to backup TA now, you can - flash back to any 534 FTF, root, make your backup, then upgrade back to 290.

This is what I don't want to do. Unlocking Bootloader on 4.3 will also compromise few features like Bionz and X-Reality. I don't think I really need them but for me will be good enough to have Full Root with Locked Bootlader and Apps to SD. I don't ask to much, so I wait.

You just took those words from my fingers. The wise way here is waiting and cheering developers to figure out how things work with Z1, 4.3 just came a few weeks ago and (hopefully) we will get 4.4 soon, so for that time you'll have to do that trickery again to keep your phones rooted.

I mistakenly took the .290 update as well and I'm now looking for a way out. This whole backing up the TA thing worries me because I'm afraid I'll lose those DRM keys and bravia etc..... Are you saying that I will be fine and all the keys will be intact if I follow this guide?
Is it possible to downgrade the firmware instead?
What would you suggest?
Thanks

Ok, so here is a little clarification
You need to downgrade to .534, root, install recovery and then flash a prerooted .290 rom from (http://forum.xda-developers.com/showthread.php?t=2572988) or one of the stock-based custom roms such as monxdified (http://forum.xda-developers.com/showthread.php?t=2463675) if you want a partially rooted, locked bootloader 4.3 firmware on your Z1. There is an instruction on how to install on locked bootloader in the thread.
Rooting on the newest version of Android 4.3.3 isn't impossible on the Xperia Z1, it just takes you more steps than normal to actually get full root access. I have a locked bootloader as well but I was able to get a rooted version of Android 4.3.3, specifically the iHackers 2.0 ROM running Android 4.3.3 with full root access. Here's how I got full root access on the iHackers 2.0 ROM:
1) Download the .ftf file named C6903 14.1.G.1.534 Global 1277-2880_R4A from the compiled FTF thread at this link: http://forum.xda-developers.com/showthread.php?t=2469191
This is a version of the original Stock Rom that the VROOT program will actually work on when trying to ROOT your phone.
2) Flash the ROM you downloaded using Flashtool (steps on how you can go about doing that should be in the Xperia Z1 General forum.) and now, you're ready to root your phone with it.
3) Download, install and run VROOT to root your phone. Again, more information on how to properly root your phone using VROOT can be found in the Xperia Z1 General forum. For me, I just turned on USB Debugging on my Z1, connected my phone to my computer while VROOT was running and clicked the green button until I got root access. It's extremely easy.
4) With Root Access, now you can download and install Dual Recovery for the Xperia Z1 on your phone.
5) Download the latest iHackers 2.0 ROM from the Xperia Z1 Android Development thread and copy it to your phone. This is hands down, the best ROM for the Xperia Z1 right now in terms of battery life. With the latest 4.3 update, I'm able to get over 2 Days worth of battery life on one charge. Battery life is much better on the new iHackers 2.0 ROM running Android 4.3.
6) Download the flashable Locked Dual Recovery for the Xperia Z1 here. http://nut.xperia-files.com/
The file is called XZ-lockeddualrecovery2.7.63-BETA.flashable.zip (8.48MB), download it and copy it to your phone, preferably the same place you copied the iHackers 2.0 ROM. To make things easier for yourself, create a new folder on your phone or SD Card in your phone and name it iHackers. Copy both the iHackers 2.0 ROM and the flashable Locked Dual Recovery.zip file into this folder.
7) With both files now copied to a folder on your phone, you're now ready to go into recovery to flash the iHackers 2.0 ROM. Boot into recovery and once you're there, do a Wipe Data/Factory Reset before Installing the ROM.
The rest of these steps are now taken directly from the iHackers 2.0 download thread on the Xperia Z1 Android Development forum.
8) Install the ROM and THEN Dual Recovery. Don't make the same mistake I did, once the installer is finished, DON'T REBOOT THE DEVICE. Uncheck the "Reboot Device" box and go back to recovery to install the flashable Dual Recovery.zip file that's in the iHackers 2.0 folder.
9) Switch Off Your Phone (Do Not Reboot). Select No to Disable Flash Recovery Confirmation.
10) Install Kernel.ftf for C6903 (.290) or Kernel.ftf for C6902 (.290) with Flashtool to get compatible Kernel and Baseband. To download the kernel.ftf file, go to the original iHackers 2.0 thread to download and flash the kernel using Flashtool. You should be familiar with Flashtool at this point since if you make it to this step, you've already used Flashtool once to flash the .534 baseband version of Android.
11) Reboot and Enjoy. Now you're running the latest version of Android 4.3 on your Xperia Z1 on a Locked Bootloader WITH full Root Access. Sure, it's not the stock version but the iHackers 2.0 version of Android 4.3 is just as good, if not better. This will certainly do until there's a better way to simply root the newest Stock Version of Android 4.3.
I've been looking into unlocking my bootloader to install custom kernels on my Z1 but the battery life and performance on my Z1 with a locked bootloader is already pretty impressive. I can't imagine how good it could be with a custom kernel.

No, if you Unlock Bootloader you will lost the DRM keys permanently with Bionz and X-Reality, even with Android 4.3, if you do not do a backup, but the difference from 4.2 is that your phone will still working properly.

Thanx man. I appreciate the time you took to explain the process step by step. One step very important you forgot to mention, Backup TA, never forget to mention that. Anyway I will check if this actually get me full root and all the stuff and when I finally will lose my patient I will start follow the guide and flashing and burning my Z1.

The instructions didn't say to unlock the bootloader, which is the only sure-fire way to lose your TA partition. However, I would agree there's no good reason *not* to back it up anyway. Better safe than sorry!

Sorry, no. In his instructions, UB is not necessary because XZDualRecovery can be installed on LB. The reason skipping the TA backup is okay is because the instructions do not unlock the BL.

[Solved] Xperia T - 4.3 not able to root

Hello
I've been trying to install Cyanogenmod on my Xperia T.
However, I need recovery (CWM) to do so, which requires root acces.
I've been able to unlock bootloader but rooting isn't a succes.
I tried all the root functions in flashtool, and some others but nothing works.
So, is it safe to downgrade my firmware from 4.3 to 4.1.2 with flashtool, root that version, and then install recovery/cyanogen?
Thanks!

Yes it is safe. You can install any custom rom from any stock firmware (unless it states in the description that you need a certain firmware).
Btw: did you try towelroot? I believe it should work on 4.3
Sent from my LT25i using XDA Free mobile app
Allright, just wanted to be sure!
I've tried towelroot but it kept rebooting, even on 4.1.2.
But I've been able to flash CM on my xperia a couple of minutes ago without problems (apparently it came with its own recovery menu).
Developer tools had a root option and that luckily worked.
Thanks for the help :good:

How to root (D5803) on Android 5.1.1 (23.4.A.1.200) without unlocking the bootloader?

Hey guys, the title sais it all!
I have some expirience with flashing roms and custom recoveries and rooting, but on Samsung phones its SO much easier then on Sony. I read through some stuff with flashboot and ADB and what not and I don't really get it. All the ''step by step'' guides are not step by step, their using terms that a normal person wouldn't understand. So I was just wondering if anyone here knew the easiest way to root my Z3 compact running on the latest firmware, without unlocking the bootloader?
http://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343
Downgrade the firmware, as the root exploit only works with older firmware such as 23.0.A.2.93.

Long story short, you can't root using the latest firmware. Follow the guide to root.
