Hi gentlemen!
I left Xperia Z Ultra forum long time ago.
Now I come back and after unboxing my C6802 model I updated up to 14.2.A.1.136 (4.3)
And now I'm trying to root this kid but vRoot not working any more.
Is there any easy way to root this 4.3 ? (I got full stock with lock bootloader)
I tried to search but there is so many threads, I confused.
(I need to root it to back up my TA and delete bloatware)
Regards.
Look at the stickies in general, but the steps would be:
downgrade to .532
root with Bin4ay's root tool
backup TA
flash wanted ftf
unlock BL
flash recovery
flash superSu from recovery

Any details? Any error? Send us your logs (console output of flashtool). Is your flashtool up to date? Do you use Fastboot mode or flash mode? I usually use flashmode.
Works fine on my Windows 8.1.

Rooting should never be easy. Cause it was intended for someone who really wants it.
I love easy, like for example, what bin4ry has done. But, if the hard way is what possible now, then the hard way it is
Thanks for the guide
EDIT :
wait a minute, by OTA do you mean download via phone?
Can it have a same result when updating via PCC or SUS?
and 2nd EDIT : just letting you know, the ftf you provided gives me a bootloop. I chose not to wipe data. Maybe will give different result when all is wiped. Dont know

Well, I think that the explanation in this thread is way more useful than the one that you quote, in which you magically get OTA update to JellyBean, I tried both and it was this that worked for me. I suggest to update the info in your thread with this explanation, unless you want to create some kind of "noob wall" to prevent non experts from getting root on their devices (mostly kidding).
Just one thing..
This method works also with superuser only (ota rootkeeper is not necessary).
I followed this way:
-flash the old ICS rom posted by lebartman (thanks again)
-root that rom using the old bin4ry tool for rooting ICS (or flashtool, I think it's the same, the important is having superuser after the root)
-update superuser to the last version using play store (most important!!)
-use the features that are also directly inside the last superuser: first check OTA survival, then check also temp unroot (both are in the info panel of superuser)
-update to JB via OTA update
-after the complete update, uncheck temp unroot in superuser
-Done (JB rooted and all 100% working!!)
My 2 cents.
Fine thanks

U checked it? I guess this is the easiest method till now.. Also, will "Enable Superuser" in setting of SuperSU app do the job in same way for those who want SuperSU instead of superuser?

Yes, I've check it. Regarding supersu, I think u can simply install it after rooting and then remove superuser..
Merci pour m'avoir mentionné dans l'OP, @lebartman.
For the moment, there are two working methods to get root for JB: this one, and flashing the prerooted ROM. For those who can't live with that and want a more simple one-click method: be patient, do not rush anybody, sometimes someone will come out with an easier way.

You can root the XTZ, but it's a bit of work... IMO the easiest way is to install a custom rom, but there are other root methods for this device...

1.) I suggest you simply flash 10.1.C.0.370 firmware and root it using the attached file below.
2.) install the latest dual recovery by NUT.

@donedos After connecting the tablet with the companion software on my mac, I got the .109 upgrade
Now I am on .109 Firmware.
- How should I flash 10.1.C.0.370? Which tool to flash, source to find 10.1.C.0.370 (search would do?)?
Many thanks

Okay, I have flashed firmware .370 to my tablet (but used SGP312 instead of 311 which is the model of my tablet!), and I have that awful UI layout with the home key and back button of the bottom left and the drop down menu on bottom right! .109 update has popped up as well.
When/if I update to .109 (after root) will my model be SGP311?
I have rooted okay, but used doomlord xploit as the file you attached did not seem to work, and I have installed the recovery by NUT.
I now have the firmware for SGP311 (UK), but only a .ftf file (853,683kb). The directions above state you should have a zip file also

You might lose root with the OTA. The awful phone layout is a consequence of Google trying to unify the UI across Android devices. It's a bit better for devs, lot worse for users. But you eventually get used to it. With 4.4, even Settings app will have the giant phone UI.

hi folks
i am expecting to get a z2 and i have few questions.
from what i ve understoud, if you want to root it, you need to unlock the bootloader, and if you want to unlock the bootloader, you need to backup TA partition first, but for perform this backup YOU NEED TO BE ROOT , and i have to admit that i am somehow lost :/
Any help around for solve my headache?
best regards
No headache, at the current time there's no root workaround. It's a catch 22 scenario you can't do 1 step without screwing up the next 1.

The whole deal is a bit confusing, yes
The so called TA partition holds your DRM keys which give you access to DRM content. These are unique for each phone and a restore of the TA partition from a different phone would permanently brick your phone. If you restore your own TA partition however, the phone is locked again and your completely back to stock again, Sony won't be able to see that you've rooted it.
Now, in order to backup the TA partition, you need to have root access. In the past this was accomplished by an exploit, which gave you root access without wiping the TA partition. Therefore you could get root access, backup TA, flash a custom recovery, flash a custom ROM and if need be, flash your phone back to stock completely.
Hope that made things a bit clearer.
I just need to have root in the safest way once i have my z2, is the exploit still up?

There is no exploit for the Z2 (yet) and no guarantee that there ever will be one. Right now, your only choice is to use this recovery which will wipe your TA partition permanently.

damm, why all phones are not so easy to root as htc.....
what are fundamental changes in your daily use once you lost your drm ?
thxx for your time
Is it possible to downgrade the android OS to 4.2 or 4.3, root it and get back to the latest version?
There may or may not be an exploit but if there is, according to what i know is that still your bootloader status should be either unloocked or unlockable. If the status is unlockable or unlock allowed no then there is nothing you can do.... Is this correct?
For instance if my bootloader is locked cuz most carrier locked phones on contracts come with a locked bootloader, if i get my phone unlocked will my bootloader status change? If not is there a way to boot such a phone.
I have a few questions on this
1. Is there a way to know if ure buying a phone with unlocked or locked bootloader ( obviously i cant open all boxes and check one by one by the command) ?
2. If the carrier locked phone have locked bootloaders and vice versa what if we unlock a carrier locked phone will the status change then?
3. Have anyone using previous xperia models with a locked bootloader been able to root so far?
Havent got one yet but as much as I am looking forward to get one these are all ofsetters.

You have to wait til 5.0.2 is rootable. Check Sony site maybe you can unlock the bootloader on lollipop.

Why do I need to wait for 5.0.2 root? Or unlock bootloader? I wasnt rooted and my zu bootloader was locked when I upgraded from 4.4.4 to 5.0.2 with Sony flash tool. All I needed was a ftf file with same region

I'm not sure if you can downgrade that way. I would try? Maybe not? If anything goes wrong you could always just flash stock again.
If you root and unlock bootloader you can move between android. I'm on 5.0.2 I can go back to kitkat anytime I want.
Has anyone downgraded from 5.0.2 to 4.4.4 yet? without having to root or unlock their bootloader. The reason I don't want to unlock my bootloader is because I accidentally erased my ta backup. That's why Im trying to get back to 4.4.4 so I can root and backup my ta again to unlock my bootloader. I just want to know if it is safe to downgrade my 6833 zu without root or unlocked bootloader
Thanks
Lollipop uses a different firmware so probably not. I didn't black up my TA .. I just went about unlocking it.
Try to flash a 4.4.4 ftf?
Yes but I want to back up my ta first before I unlock my bootloader because if I don't I'll lose the xreality keys and warranty. so it has different firmware so 5.0.2 won't be downgradable to 4.4.4? so you suggest I wait for a 5.0.2 root.
Sorry yes I wanted to to flash a stock 4.4.4 ftf with Sony flashtool
I figured I would give an update I was able to downgrade from 5.0.2 to 4.4.4 ftf with a locked bootloader without any problems

So someone who gets an Ota for lollipop can turn around and root their phone? The only reason you're rooted is because you downloaded a pre rooted rom.
So again lollipop is un rootable
So has anybody followed this guide?
Was it effective? I am reluctant to unlock my bootloader but on how my xzu sounds on my earphones, I am very eager to install V4A.
i am go to sony service center for downgrade the xperia z ultra from 5.0.2 to 4.4.4 but they said xperia z ultra chipset cannot support downgrade there any solution for downgrade bcoz my z ultra only get software by pc companion and flashtool and custom rom cannot work plz help me i flsah custom rom then device stuck on sony logo

You're in the wrong device section. This is the Z Ultra forum. Anyhow, I see that you have the ZL, so I'll make this short. Tell me your region, and I'll make you a 4.4.4 FTF.
EDIT: I'm assuming the C6506 is the American version of the ZL, so the only 4.4.4 file that's available is the one for Puerto Rico. I'm building it now, so I'll put a link to it here when it's done.
