I took a look at the thread, and people report that .526 boot.img is perfectly working with .532 firmware. So you can flash it on fastboot without problem.

No, you don't need to unroot your phone. Just update and root again, and you'll have to re-do the apps2sd each time. Only when you unlock your bootloader you no longer can make update with any Sony programs.

[Sony Xperia Z Ultra] chewdan:
thanks for reply.

sorry another question: "re-do the apps2sd each time"? u mean after update new firmware, apps previously move to SD will "auto move back to ram"??

no interest to unlock my bootloader since i only need to move app to SD.

thanks.
[Sony Xperia Z Ultra] bASKOU:
No they do not move back. But I just wonder if after updated your phone it'll work fine or if you need to download data again and move them to SD. Maybe will work directly, as you just update and not wipe and install again, I certainly said something wrong. Never used it and don't know if it modify android system or rewrite on the app directly.

Hi guys! Thanks for the guide! I just upgraded from the Note II to a white Z Ultra. Loving the screen. The model says C6802 so I guess it's the international non-LTE variant.
[Sony Xperia Z Ultra] f2:
Does the guide in post #3 work with Windows 8? I am remembering that I saw a post where it was recommended not to use Windows 8 for rooting.

Thanks!

//edit: Just to confirm: There is no issue rooting & backuping your TA partition on Windows 8. Just let your Xperia Z Ultra install all the drivers for you the first time you connect it to your PC.
[Sony Xperia Z Ultra] bASKOU:
Most people who can't root do not install properly the drivers and do not enable usb debug. You can run almost programs on windows 8, or simply can run it with different compatibility.

TWRM Recovery

Thanks for your infomation!

I'm using .532 firmware and v5 kernel.

bootloader was unlocked.

when i wanted to enter recovery

pushing the volume up button was well work.

so i could to use CWM.

but when i pushed volume down button i couldn't entering TWRM.

it just entered CWM.

anyone have same problem?

Unlike the V4 kernel the v5 kernel only has CWM installed :( No TWRP on that one... Dev said he would add it in a later version.

Question: Should I be scared and stay away from buying XZU, with all the Screen of Death and Black Screen issues i've been reading?! Was this already fixed? Is this just an isolated case?
[Sony Xperia Z Ultra] bASKOU:
SOD is not something to be scare about, and the XZU isn't the only android device having this issue. This doesn't damage the phone and it can be reboot without trouble. Only thing is tat it seems to be related to the backlight so best is to not touch optimized backlight and adapt to lighting condition settings.band for what I know the SOD doesn't come all the time. I got 2 SOD over 1 month and half.

Also I think Sony doesn't work on it because they are in 4.3 update process that might start coming around the 4th November.

Hello, all.

I just rooted the phone with the provided method....my phone works "okay" and the root did work. However, my screen never turns off completely. When I hit the power button to sleep the phone, I can tell the display isn't completely turned off. The screen is black in color, but I can tell the backlight is still on.

Does anyone know why this is happening?
[Sony Xperia Z Ultra] baileyjr:
I've heard of that problem on AOSP Roms but never the stock ROM, what firmware are you running?
[Sony Xperia Z Ultra] cms062407:
I am just on 4.2.2...whatever the completely stock OS is.

ALSO, the phone takes forever to reboot! I am talking..2-3 minutes to reboot.

Extract the archive to get the usbdriver folder. Put phone in fastboot mode.. When Win fails to find the driver, point it in the direction of the android_winusb.inf file..

Or In device manager if you have an unrecognised device, install the driver from there.
[Sony Xperia Z Ultra] 3mL:

First impressions is that it is big but not hardly as big as I expected, it fits nicely in my pockets.

I'll stick with .510 until the new firmware releases. Can't say much about the camera just yet but I got the Camera FV-5 app that should help a lot.

Did you flash the 526 bootloader from this thread http://xdaforums.com/showthread.php?t=2426736 with CWM and TWRP and your current firmware is .257? If so then....

1. Boot into CWM or TWRP by holding the volume down button while it is booting.

2. Once you are inside CWM or TWRP, flash the

UPDATE-SuperSU-v1.65.zip file

found here http://xdaforums.com/show....php?t=1538053

3. After flashing that, turn off your phone (hold power + volume up until phone vibrates and turns off)

4. Finally flash the .257 firmware again using flash tool but

EXCLUDE

everything (option on the right side of flash tool)

except the KERNEL

You are stuck in a boot loop since the old kernel with CWM and TWRP cannot boot the latest .257 firmware. You need the matching kernel to make it boot. But for us to get root, we needed CWM or TWRP to flash the supersu file hence we installed the older kernel to do so. But we need to reflash the 257 kernel to make the device boot once we have installed supersu.

What's the benefits with an unlocked bootloader compared to locked bootloader?
[Sony Xperia Z Ultra] iBuzman:
^^ arguably nothing now a reliable dual recovery is available for locked bootloaders :)

sent from my Sony Xperia Z Ultra
[Sony Xperia Z Ultra] baileyjr:
I would have to disagree.

You can only flash a stock ROM/Kernel with a locked bootloader. So no CM, no AOSP etc

You also can't flash SU to system partition with a locked bootloader I believe, so no easy rooting.
[Sony Xperia Z Ultra] iBuzman:
^^ good point re cm, aosp & derivatives, thx for the correction.

Not sure about su.. I'm on stock rom running locked bootloader recovery and system partition flashed su, but I've an unlocked bootloader hehe.. Guess I should have remained quiet and appearing ill informed instead of chipping in and confirming it ;)

I did everything in this guide, and I currently have .257 with root. In order to install recovery, do I need to find a newer file, or could I use the one posted here?
[Sony Xperia Z Ultra] speculatrix:
I think there have been enough changes that the first post should be amended to highlight that firmware 257 requires different processes to unlock the bootloader!
[Sony Xperia Z Ultra] fastest83:
No it doesn't.

FW 257 requires a different rooting process, which is rooting on FW 532 as usual with vRoot or Kingo, installing Voodoo OTA Root Keeper, updating through OTA (and changing the build.prop if you can't find any OTA updates in your country) keeping root intact.

Rooting and unlocking the bootloader are two completely different things.

While rooting with an unlocked BL is always possible through recovery, simply flashing the SuperSu.zip file, rooting with a locked bootloader depends on the actual firmware and whether they found an exploit for that or not.

Unlocking the bootloader is possible on any FW, provided that your device isn't provider locked.
[Sony Xperia Z Ultra] speculatrix:
ok, sorry, the third post should stop mentioning vroot then?
[Sony Xperia Z Ultra] fastest83:
Yes, it definitely should. It should also mention that vRoot and Kingo are under "investigation" at the moment under the suspicion that they could collect sensible data while rooting (IMEI etc.), so that if you do root with those, you should know what you're doing.

Not that modding ANY phone in ANY way is ever 100% secure, but it's better knowing than not knowing.:fingers-crossed:

[MENTION=4609488]wedgess[/MENTION] How about Kingo? Is it "safe" to use now since the dev (allegedly) removed the IMEI collector?

Kingo is still the same, however their developers are working with us put our concerns to rest.
[Sony Xperia Z Ultra] shaolin95:
So I am getting my phone tomorrow and was going to use this post to get it ready for rooting and installing ROMs etc. Are there other alternatives since those links are gone for now?
[Sony Xperia Z Ultra] LordManhattan:
Well, the root situation for the ZU/Z1 isn't pretty these days. It's currently not possible to directly root firmware version 257, so we have to downgrade to 532 and use Kingo. After you've rooted you (may) have to change the CDA in the build.prop (takes 30 sec.) so you get the OTA update to 257.

Just follow this guide.

Wow! Anyway, the Sony charger I got was rated at 1.5 Amps or 1500mA, the new Samsung chargers (at least my S4 charger) is 2 Amps or 2000mA.

It's a bit extra i guess, but it might also depend on the internal charge circuit of the Ultra - having said that, the Ultra seems to charge quicker when plugged into the Samsung charger, rather than the Sony, or even the blackberry 1000mA, for that matter.

That must be one hungry game - running on full brightness, and Wifi, you're not streaming Bluetooth music at the same time are you???
