[Q] Clarifying question about 4.3 root.

This is for my curiosity and many other users who I know are wondering the same thing, I've searched for this, but can't really find anything that answers it to my satisfaction.
So I'm running 4.3, with build number .290
I want to root my phone, but I know I need to flash .534 back to my phone. As far as I know, THIS will stop my sim being recognised by the phone. Do I then need to ROOT the phone, and then flash .290 again for the sim to work again.
So which .290 flash will I use? Just the normal FTF file for .290?
Thank you, I'm an active contributor to the forum, but I like to be super sure about what I'm doing before I do it, and I gather many other users do. The reason I'm asking in such detail is because my phone was rooted before, I updated (by mistake) to 4.3 and then flashed back to .290 where it stopped my sim working. Took me a few hours to work out how to fix it, as the pccompanion wasn't working for me!
Thank you!

why don't you unlock your 4.3 rom and flash a recovery to root it ? would be easier

If you want to flash the firmware you have, follow this guide from part B to part C, then you will have a ftf copy of your current firmware.
About the root thing, downgrade to .257 then .534 so you don't have the IMEI and signal issues. Then root and OTA to .257 and then, if you get OTA update to .290 go for it, but some people said that you will only get partial root access.
So you will have to either flash a prerooted firmware or unlock bootloader and turn off Sony's RIC and then root the normal way.
To unlock bootloader, just follow the instructions here but don't forget to backup the TA partition using this guide.

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/2013/12/19/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.

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.

[Q] How to backup TA without root

Hey everyone,
I spend a lot of time trying to root my wonderful new Xperia Z1, the problem is that I want to make a TA backup before I unlock the bootloader but I can´t find a method anywhere to root the phone without unlocking the bootloader. And as far as I know you can only backup TA with root access...
Do you have any good idea how I can solve this problem?
Thanks in advance
Edit: I´m running android 4.3 /.290

You didn't search very well. You can root your phone with Locked Bootlader with this method only, by NUT .

Sorry, i can't understand how you can miss all this stuff. Did you saw the Video Tutorial? There Shem explain everything, you have just to read carefully. Downgrade to .534 FW provided by NUT to not lost IMEI, Root with Bin4ry, update to .290 like the instruction saying then the same for .136.

Ok it worked now, sorry, I just had no idea how that should work, the video explained a lot.
Thanks for answering anyway

Root for 4.3

when you think that it could be possible to root our Xperia T with 4.3 update?:fingers-crossed:

Downgrade to 4.1, root, upgrade with root to 4.3, this is the best way currently.
I wouldn't be surprised if we don't get a direct root method for 4.3 since we can do what I said above

That's the method if bootloader is unlocked, there's a few of us not willing to unlock it yet.

Use flashtool to roll back to 4.1.2, doomlord's rooting technique for rooting that firmware, jump to the development forum to grab the touch recovery by peetr, and then use darklord's deodexed stuff to get rooted 295 - did it today and the steps are relatively well mapped out for you - I can vouch that it works for locked bootloaders on stock firmware :good:

Yes, you can downgrade, but you can't upgrade using Sony Update or Companion, you can flash rooted rom via recovery. If you upgrade with Sony tool you'll loose root.

What, rooting fresh installed 4.3, not flashing 4.3 custom rom?

I have locked bootloader, I only went back to 4.1.2 with flashtools, then installed root and CWM, after that flashed Dark Lord's 4.3 stock (the Bond one) and the SuperSU zip in recovery.
Everything running correctly.

Somebody will try to root it once the Z2 is launched: you can't downgrade that, but if a working root exploit is found it will probably also work on previous xperias.

with 4.1.2 i have root and how all we know with original update the root permission were lost.i don't want to unlock again my bootloader.i prefer that it will be locked,for keep it most possible original,because i like the sony software.i want the root only for xposed and his modules.

Rooting

I have latest official firmware JB 4.3(12.1.A.0.266).
Now i want to root it.
Is there any way.
Thanks

Yes there is. However you need to unlock your bootloader for this.
Tutorial for Bootloader unlocking: http://forum.xda-developers.com/showthread.php?t=2354721
Tutorial for Rooting: http://forum.xda-developers.com/showthread.php?t=2646193
However for unlocking bootloader you need to create a backup of the TA partition and this requires root.
So there is an loop in this issue.......
What some users do:
- Downgrade back to 4.1.2 (see my tutorial about Flashing with Flashtool)
- Root it
- Backup TA
- Unlock bootloader/Install CWM
- Install custom 4.3 rom with root
