Fire up Sony PC Companion on your computer and update through that instead.

I was hoping to have this ota file and hopefully retain root...

You'll lose root either way. Just update it through PCC and root it.

Thanks for the reply. So, is my only option is to do the unlock and relock bootloader root procedure?

I believe so on 4.3 (.290)
As time goes on this might be the only way to get root - the more secure Sony/Google (or any OEM) make android the harder it will be to find exploits to gain root.

Did you tried like this
1.Before update simply open superuser settings 2.scroll down to the bottom enable Pro 3.check survival mode 4.uncheck Enable superuser 5.install ota update 6.after reboot enable superuser

LordManhattan and blueether is correct. Tried 3 times what chemcup suggested and the ota update just would stop halfway... Hopefully that they would go easier on the next upcoming update...

- Flash modified kernel via fastboot
- DO NOT relock the bootloader, the phone won't boot otherwhise.

Can't update OTA 4.4.2

I had flashed stock recovery from this one http://forum.xda-developers.com/showthread.php?t=2568799 but after i finished i can't enter to stock recovery. It show me red triangle error sign and stop. I think because of i flashed different version of recovery. Right? If so how do i get 1.23.707.1 stock recovery or how can i upgrade 1.54.401.1? Any idea for this problem please?
Here is my processing step...
1. When i get ota update, unlock bootloader
2. Then flash stock recovery from above link.
3. Lock bootloader
4. My device is still rooted and i download ota update. Then i install.
5. Device restart and start loading but may be round about 20% it start show me red triangle and stop processing.
Here is my device version
CID-HTC__044
hboot-2.46.0000

Well your first problem is that the Bootloader has to be locked for the OTA update to take affect. Make sure you have Stock Kernel, Rom and Recovery Installed.

[Q] ROOT

Hello, I want to root my XPERIA Z2 but I have never done this before, so I have some questions.
1) If I flash the Recovery used to root, will the stock ROM be affected?
2) After root, will I continue receiving the official updates? If not, how can I update it manually?
3) Can I save the stock ROM to an image for future unroot? How?
4) What do I will lose with root?
To root your Z2 you need to unlock your bootloader and flash a kernel with recovery included of which within you can flash a root zip
Kernel and system are seperate so your rom wont be affected but they do depend on eachother
Root doesent affect anything at all and neither does unlocking your bootloader, you lose nothing at all
You can backup your rom in cwm and restore later, you can also unroot from within the root management app

But in this case NOPE..
3.just flash ftf ...available in general section..
by flashing it will automatically unroot your device.
4.rules kept on device...[emoji6][emoji6][emoji6]
but if you unlocked bootloader.. then 1.warranty 2.official updates..3. Vulnerability security..

Does rooting screw up DRM keys or whatever like it did on other sony devices in the past?
I am REALLY thinking about this as my next device, and if I can't root without screwing up the device, I'll be put off.
TIA

Think of it like this, your drm keys with Z2 are currently uselss, losing your drm keys breaks nothing, (ive tested this)
(in simple words = almost 0 drawbacks of unlocking your bootloader)
What you should be more worried about is your warrenty/garentee , it is voided when you unlock your bootloader

Unlocking or relocking your bootloader resets your device so you cant realy win
And you cant relock on a custom kernel, it has to be totaly stock

I care more about the DRM keys, only because I assumed they added functionality that woudl be lost wtihout them, as they did in previous Sony devices.
Are you saying that, with the Z2, this is not the case and that the DRM keys don't matter at all?

update to .402 without losing root?

Hello, Ive just rooted my z2 with towelroot on .55 and installed the xposed framework. I received the ota update from .402, is it possible to update without losing root? Like with superSU's survival mode?
Already thank you
With OTA survival it should Survive the OTA update
Try it, if you lose root you can simply reroot easily enough

Thanks, but should I delete the xposed framework? They say that xposed framework screws the update up.
Unlock bootloader -> Flash .402 FTF with flashtool -> Flash insecure kernel via fastboot
Even if you lose the root... I think root for .402 is out already.

yes you can, but 95% you will loose root after that. But nothing prevents you from rooting again with towelroot or Easy Root Tool (which is better).

Updating with PC companion while rooted

Hi, all.
Today I installed the PC companion on my computer, and I proceeded through the requisite steps to update to 5.0.2. It's currently in the updating process, but I just realized that I forgot to unroot it (I used KingRoot to root stock kitkat to avoid unlocking the bootloader) and I've heard that root can interfere with OTA's, causing them to fail. Has anybody here tried updating a rooted device "as is" (that is, without taking the time to unroot before OTA), and have you guys encountered any issues doing so, either in the process of updating or after the update has been completed? Just want to know if there are any consequences to what may be a mistake.
That's no problem at all
Sent from my C6833 using XDA Free mobile app
I use this thread instead of creating another one, I'm unlocked, should I update (once 5.1 is available) through pc companion, or is it not recommended? I remember not to accept any OTA, but I don't remember if it's safe to update via pc companion...

I've updated my rooted device using the PC Companion, but it requires me re-locking the bootloader temporary, then unlocking and rooting it again after the update.
At the moment however there is no way to root 5.1
