Do you have the stock image of the ROM you have? If so, simply go back to stock recovery and dirty flash it (meaning simply flash the ROM without wiping). There might be other methods to unroot, but I like this one the best as it returns your system the way it was prior to root.

You want me to put the hammer down?
[Sony Xperia Z Ultra] anthonyp326:
Hmm never done that before might have to look that up on how..I don't have a stock image or ROM I used towelroot to gain root that's it
[Sony Xperia Z Ultra] egzthunder1:
What ROM are you on?

You want me to put the hammer down?
[Sony Xperia Z Ultra] anthonyp326:
Didn't install a ROM.. Just the one that came with the phone . only did towleroot on stock still on 4.4.4
[Sony Xperia Z Ultra] egzthunder1:
Actually... Better yet. In the Settings in SuperSu, there is an option to remove root. Try that. Should work just fine.

[Sony Xperia Z Ultra] anthonyp326:
There is no super user with towelroot
[Sony Xperia Z Ultra] egzthunder1:
It you are rooted, go to the play store and install SuperSU...

You want me to put the hammer down?
[Sony Xperia Z Ultra] gidal:
I did what you recommended and installed SuperSU from playstore.

Ran it and it wanted to update itself before running, asking normal or CWM/TWRP method.

NM: Just needed reboot - it's installed now.

[MENTION=3534362]blueether[/MENTION] there is a GPe build of CandyRom in original development thread.

[MENTION=252661]egzthunder1[/MENTION] can this thread get stickied?
[Sony Xperia Z Ultra] egzthunder1:
Technically, this guide does not even belong in this section as it is not development related. Having said that, there is already a guide under General by Lord Manhattan that somewhat brushes upon many of the topics described in here by blueether, so moving it there would make little to no sense to me.

So, I guess that for the time being, or until I can think of a better solution for placement, I guess it would be ok to have it stuck in here.
[Sony Xperia Z Ultra] adfurgerson:
Thanks, I see the dilemma this device provides. It doesn't warrant it's own forum or having GPe General and Q&A sections in this forum.
[Sony Xperia Z Ultra] Galaxy Lover:
Hi

I has question

I can not copy files to SD card. What must I do to solve this issue? only rooting?
[Sony Xperia Z Ultra] adfurgerson:
I think after rooting you will need to download.and run an app.called SDFix.
[Sony Xperia Z Ultra] Galaxy Lover:
I did root my z ultra GPe.

So now, where can I find the app that called SDFix?

if any one know, please help me.

[Sony Xperia Z Ultra] knives of ice:

[Sony Xperia Z Ultra] stjoemail:
Just to share .. I have managed to root my sony ultra z gpe 4.4.4. using towelroot after many hours trying different ways posted in xda ..

finally what worked for me:

1. turned on wifi for network connection

2. goto www.towelroot.com and click on lambda symbol to download towelroot apk, run it .. DO NOT click on make it rain cos it will make hang

3. click on 'welcome ...' several times till the box with the numbers appear 133701040 .. change to 133701060 then click on make it rain ..

4. your device will be rooted ..
[Sony Xperia Z Ultra] blueether:
/me digs: just like it says in the OP?
[Sony Xperia Z Ultra] stjoemail:
I tried the OP steps but this step caused my device to freeze:

- Try this for "device not supported." You'll have to tap the welcome to towel root icon 3 times and change the string to:

So for those who face similar situation like me, skip that step, just tap welcome to towelroot straightaway..

Bootloader Question

Im using the sony way of unlocking my BL. I keep getting "is a directory" after i type in terminal fastboot devices...... Im following the directions as it gives me ...and keep getting stuck....Thank you for your help....
[Sony Xperia Z Ultra] blueether:
Try from flashtool http://flashtool.net and make sure all drivers are installed
[Sony Xperia Z Ultra] tuliouel:
Let me know if I got it: there's a common Z Ultra, and it is rootable AFTER upgrading the firmware to KitKat. And there's the GPe one (Google Play edition), which should be rooted as soon as it is unpacked. Right?

By the way, in case I got it as a gift, what procedures should I take to know which one I got?
[Sony Xperia Z Ultra] egzthunder1:
No. Root is never enabled out of the box simply because it is a security risk. Some devices are easier to root than others but none come rooted.

There are two versions of this device, both of which come with a locked bootloader. The difference lies in the branding and the software:

The regular Sony Xperia Z Ultra comes with Sony software (Xperia launcher, camera, etc)

The gpe edition is not an Xperia device (its name is actually Sony Z Ultra Google Play Edition - without the Xperia as part of its name). And as you may have guessed, it comes with Google experience type of software (basically aosp with everything that has Google branding on it).

As far as rooting, I am not sure of a way to root lollipop other than flashing a rooted ROM, which last I checked is only available for the Xperia version. I think that Doomlord released a rooted .IMG for the GPE but I haven't seen comments of any kind from people successfully flashing it.

Telling which one you got is as simple as looking at the box or even the device itself. If you see the word "Xperia" anywhere, you got the Sony variant. Also, look at the launcher. If it is not Xperia launcher, then you got the gpe one.

Hopefully this helps...

1. Never reveal everything you know;

[Sony Xperia Z Ultra] tuliouel:
Thanks a lot for the reply.

Now I know I got the Xperia one, not Google's branding.

Then I said " rootable AFTER upgrading the firmware to KitKat", I was acctually asking: "Should I update the firmware to KitKat (which is already available, acording to Sony's website) and only after getting the device rooted? Or should I root it right out of the box?"

According to your answer I may assume it can be done in both cases.
[Sony Xperia Z Ultra] egzthunder1:
AFAIK, KitKat can be rooted up until 4.4.4 by using Towelroot.

Yep, update to 4.4.4 (x.x.x.108 or 118) then root with easyroot for xperia - the the guide thread in the general section

[MENTION=3534362]blueether[/MENTION] [MENTION=252661]egzthunder1[/MENTION] [MENTION=2784807]DooMLoRD[/MENTION] - Hoping one of you can help.

I do not have access to recovery. Stock or Custom. Phone is GPE, but not able to get into recovery mode.

I have OS installed, not rooted at the moment, and access to unlocked bootloader. How do I get it going? Trying to enter recovery any which way yeilds a black screen.

Can I write back stock system.img, recovery.img boot.img using fastboot?

What about flashtool, anything that I can use there to help me? Are there any flashtool based packages?

Thanks! Much help is needed.
