as you now have an unlocked bootloader and a modified kernel all you have to do is flash SuperSu update from recovery

[Sony Xperia Z Ultra] zaxharu:
Hi sir, i have a question regarding step no. 5....update to 757 again. How? Can i flash 757ftf thru flashtool or use pc companion to update?

Im confused.please correct me if im wrong.. You cant update your firmware by flashing ftf file in flastool if your unlocked. Am i right?

If your device is already unlocked and you wish to update by flashing ftf thru flashtool, will this relock your phone or you will only lose your root but not the unlocked state.

Sorry just a noob.
[Sony Xperia Z Ultra] blueether:
When you flash a (full) FTF you will lose root, and it can be done on either a locked or unlocked bootloader. WHen you have the new firmware just flash jackie099's kernel (this will give you recovery) and then flash supersu update from recovery to get root.

with an unlocked bootloader we can gain root on any new firmware just by flashing su from recovery. We normally have a kernel with recovery within a day or so of the first release of the new firmware
[Sony Xperia Z Ultra] zaxharu:
Thank you so much Sir. One more question rwgarding the downgrade. Ive research and watch video tutorials but im quite concerned regarding which to exclude in flashtool when downgrading..there is an option to exclude somethings in flashtool right? When flashing NUTs 532, should i exclude system and baseband or should i leave all of thwm unchecked.

Thanks in advance
[Sony Xperia Z Ultra] blueether:
When downgrading with [NUT]'s FTF flash the whole think (see my downgrade thread)
[Sony Xperia Z Ultra] zaxharu:
Yes sir, ive read it. But it says i should exclude evrything except kernel and system.which means i should tick/check options like baseband in the ecxlude except system and kernel. Am i correct?
[Sony Xperia Z Ultra] blueether:
If you use NUT's ftf then you need to flash everything

[Sony Xperia Z Ultra] TheDiddlerMan:
After scouring the internet for information on rooting my Bell Ultra Z (14.3.A.0.757) you couldn't be more right with your "An unlocked bootloader solves everything". I had no idea that the bootloader would be carrier locked on this device or else I would've waited to find a non Bell branded Ultra Z. Anyhow, there's not much I can do about that now.

Would anyone be so kind as to point me in the right direction? I know I need to downgrade to at least .532 to be able to obtain root, but most of the tutorials I've come across all mention needing to unlock the bootloader.
[Sony Xperia Z Ultra] LordManhattan:
You don't need an unlocked bootloader to downgrade.

- Install Flashtool

- Download 532

- Flash it

Check the first post for links etc.

Sent from my C6833
[Sony Xperia Z Ultra] doctahjeph:
Pardon my ignorance, but if I am already on. 532 do I still.need to.run NUTs 532?
[Sony Xperia Z Ultra] TheDiddlerMan:
Thanks for the direction, LM. I finally managed to get my C6806 downgraded back to .532. I'm trying to root it using the Bin4ry tool kit, and have ensured the device is visible with the stuff\adb devices command, but when I select "2" New Xperia Root by Goroh_kun, I receive the prompt "Now unlock your device and and confirm restore operation". I unlock the device and choose restore, and the device reads "restore started" followed immediately by "restore ended". The cmd window states to enter "services" on the device followed by "display" and to wait there. I left it for about 40+ minutes but nothing happens. Anyone have any idea of what I'm doing wrong?
[Sony Xperia Z Ultra] doctahjeph:
I am in the exact same boat. I am researching the issue now. Will let you know what I find.
[Sony Xperia Z Ultra] TheDiddlerMan:
Option 0 ends with "failed to get root" and then phone reboots. I've got everything installed properly and I'm truly stumped. Since I installed .532 my signal is going from 4 bars down to no service without even moving the phone. Anyone know how I can get my phone back to its original state?
[Sony Xperia Z Ultra] blueether:
Odd, it should work you could try [NUT]'s tool. as for the signal being dead, read the downgrade stickie I wrote, it explains why and the fix (it also has a link to [NUT]'s recovery/root tool)
[Sony Xperia Z Ultra] TheDiddlerMan:
Thanks Ether, [NUT]'s tool worked for me and I'm now rooted again on .532 (C6833).

Ideally I'd like to get back on my stock rom (Bell Canada model C6806 with locked bootloader) while maintaining my root access. Does anyone know if this is even possible with a locked bootloader?
[Sony Xperia Z Ultra] zaxharu:
I dont think its possible. Once you get back to stock by either flashing ftf thru flashtool or use pc companion, youll lose your root
[Sony Xperia Z Ultra] TheDiddlerMan:
I sold my locked carrier locked bootloader Ultra Z and picked up a C6806 from the Sony store that can be unlocked. I downgraded, rooted, backed up the TA, and then unlocked the bootloader. How exactly do I get back on .757? I tried to update through OTA but it didn't work. Am I supposed to flash a .757 ftf?
[Sony Xperia Z Ultra] halifage:
Yes. Just make sure it is for your specific model ;)
[Sony Xperia Z Ultra] TheDiddlerMan:
I dont know why I'm struggling so much with this. I've been trying to do everything very carefully but I keep running into issues. After I unlocked the bootloader I attempted to upgrade back to .681 using some of the available FTF files. My Xperia Z Ultra is a C6806 from the Sony store in Canada. I tried to use a generic US ftf of .681 and when it booted into Android after flashing the text was much bigger than usual on the country selection page and my touch screen wasn't working. I then managed to located a Canadian .681 FTF and flashed that but my touchscreen is still not working.

Edit: Okay, I'm back on [Nut]'s .532 firmware. It's the only FTF I tried that got my touchscreen working again. Is there a specific Canadian .757 FTF that I should be flashing now? I just need to get back onto .757 with my bootloader still unlocked so I can root it and remove the bloat.

Edit 2: The reason for the unresponsive touchscreen was because I foolishly flashed a C6906 ftf instead of C6806. I'm now running on .681 (US Generic) and things seem pretty stable and my bootloader is still unlocked. Now, my remaining question is how do I get on .757, so that I can root and be done with this once and for all?

[Sony Xperia Z Ultra] TheDiddlerMan:
Thank you very much. You guys have all been a great help. I'm finally rooted on .757! It only took me about 3 days and 2 different devices.
[Sony Xperia Z Ultra] LordManhattan:
Hah, it's no joke being new to Sony. I was incredible lost when I got my Ultra and probably spent around 3 hours straight to root it the first time. Now it only takes around 3 minutes, so that's an improvement. You'll get there too.
[Sony Xperia Z Ultra] zaxharu:
Yes, their very helpful here, especially LordManhattan.

Can someone explain a little bit more on how to root the GPE Z Ultra, because I never had a Sony device before and I'm a bit lost and don't wanna risk anything.
[Sony Xperia Z Ultra] blueether:
Follow the detailed instructions in the OP, in this order:

Downgrade to .532 (see my sticky in this section)

Root using bin4ry's tool (option 0)

Back up TA

Flash latest FTF (757 at the moment)

Unlock Bootloader

Flash rootable kernel and recovery (jackie099's)

Flash superSU

Edit... Follow the instructions in the GPe guide in the GPe section: http://xdaforums.com/showthread.php?t=2742236

Please help? Question.. I'm buying the ultra gpe device..supposedly doesn't have ta because it doesn't use xperia apps and stuff. My question is if I unlock boot loader and root will I be able to run the new android L when it comes out? Because u can't relock boot loader?
[Sony Xperia Z Ultra] blueether:
The GPe does have a TA partition, and at the moment we can back it up after rooting with towelroot. Use the same method as for the ZU
[Sony Xperia Z Ultra] anthonyp326:
OK so root then use the tiny tool to back up ta? With the latest firmware can unlocking boot loader work?
[Sony Xperia Z Ultra] blueether:
There seems to be one person that is having trouble rooting on the latest FW, but unlocking the BL should always work
[Sony Xperia Z Ultra] anthonyp326:
So just to make sure this is clear and I appreciate ur help..so on gpe device.. Root using the tool.. Save ta using the tool.. And then use the the sony site to unlock boot loader.. ..last question if I unlock bootlaoder I will not be getting any updates from google fore latest version right? And if I just root and don't unlock boot loader I can receive update still from google ota?
[Sony Xperia Z Ultra] blueether:
Yep, have a read of the guide in the GPe section, should be more or less up to date

in short maybe

I think the last 2 updates flashed ok on unlocked bootloaders (with root?) I don't have a GPe to be 100% on this.

One other step I would do is to make a backup of the TA after you have unlocked the BL as this will make locking/unlocking very simple with no data wipe if you latter decide you have to do this.

Hello,

My new Xperia is stuck on 4.2.2 Build .257 , the easy root tool don't work, and I don't know how to upgrade this phone. Sony Companion says the phone is up to date.

If I could keep the original bootloader if would be a good thing, as I just want to get the latest official stable rom and if possible get root access.

thank you Blueether for the quick response, to tell you the truth i am a bit lost here with my new Xperia Ultra .757. it clearly specifies that i need to downgrade to .532 and then make a TA backup and then go back to 757 and root again and unlock the bootloader. I really searched and found only one link that gave me the .532 and it downloaded for ages and stopped. Really confused, i have rooted about 6 or 7 tablets and smartphone from easy to hard but this one is confusing me only by reading the forums. I am very lost. Any further help apreciated.

This is the the link from the heading "root all things" it uses towelroot exploit which made all the other other methods unnecessary.

http://xdaforums.com/showthread.php?t=2784900

The main concern is obtaining root then backing up TA partition so your DRM keys or saved before unlocking bootloader. There is another thread here that you may want to look over.

Thank you adfurgerson. That was simple as I thought, too much information and ways to root for this device but on the other hand it all is a very hard work from our devs. Thanks to all. Today I shall attempt root and all that goes after but I do have one last question: I am on .757 and it offers me a update I think .108, shall I update first before root or go ahead from .757? Once again thank you all?
[Sony Xperia Z Ultra] adfurgerson:
You are welcome. I would let it update first then root, again I want to stress the need to backup the TA partition before unlocking bootloader. Good luck and enjoy.
[Sony Xperia Z Ultra] nickfar2000:
Good Afternoon Everyone new to the Sony forum, coming from a Note 2 & must say I am loving the phone however after scanning through the OP just want to make sure I am understanding this, as whenever something is written in Bold Red Print telling me to downgrade to .532 if I am on a fresh .757 then root etc... then I tend to think that it's typed and there for a reason, with that being said from what I'm reading further I'm understanding that geohots "root all things" will root .757 including the most recent 4.4 update, then backup partition and unlock bootloader......hence downgrading to an earlier version of android is no longer necessary. If someone can confirm this for me that would be great, thanks in advance
[Sony Xperia Z Ultra] adfurgerson:
Quick answer is downgrading is not necessary. I personally used the dualrecovery from second link of previous post. I then made a Nandroid backup, used the tool from cross development section to backup TA, then unlocked bootloader. I can state that restoring that backup will return the bootloader to locked, but can't say whether the TA partitions were restored or not.

Thanks adfurgerson, much appreciated
[Sony Xperia Z Ultra] nickfar2000:
So used all thing root exploit and couldn't get it to recognize my ultra, just kept trying and I guess I am rooted.....?...... the ATR said it did not root, but was able to install Super Su but after I did I tried to update su binary via in app, and it said it failed, told me to restart, then low and behold root check shows root, and super su seems to be working as it granted root checker app super user, however A. Busybox would not load, is that normal? I mainly rooted to debloat, and use xposed, so B. as long as I dont flash recovery and I am just stock rooted I should be able to restore via stock recovery without any problems, if I need to right? Also I have looked but can't seem to find a post about what apps can be froze or removed without problems C. Does anyone know of a post dealing with debloating stock 108.

[Sony Xperia Z Ultra] H. E. Pennypacker:
You can flash the GPe ROM on it, yes, but you won't receive OTAs since that will brick your device. You should wait until Lollipop has been released for the GPe model and ported to our Ultras.

I have noticed that Sony have advised "Sony Z Ultra Google Play edition devices will be first up – we’ll be back with more details on that soon". Do we know or have an Idea of when this will happen? I am betting it will be around January 2015 if not February

Source link: http://blogs.sonymobile.com/2014/10...d-5-0-lollipop-to-the-entire-xperia-z-series/
[Sony Xperia Z Ultra] H. E. Pennypacker:
Nah, two-three weeks after release is more probable. The GPe devices should get updates shortly after Nexus models, so we'll probably get it a week or two after the Nexus 4, 5 etc, unless something unexpected happens. Sony has Lollipop up and running on the Z1, Z2 and Z3 already after just a couple of days after source release, so we'll get it soon is my guess. Note that i'm saying " my guess" which is still that; a guess. A calculated guess, but still.
