[Q] Failing OTA update after unroot(.108) - Sony Xperia Z Ultra

Hello!
My phone can't seem to accept the OTA file, even after I've unrooted it. I don't have custom recovery and I have a locked bootloader.
The error message is "The file could not be verified" which I supposed was because of the root, apparently not.
Anyone know what's up? It's the standard C6833.

It`s because Rooting changes sone Files. Just back up your Data and use the Update Centre for reflashing

Alright I understand, I thought a unroot and removal of supersu would suffice.
Update center, that's the Sony PC companion yes? Won't I loose all my data?
Even with a backup, don't I have to set up the whole phone again? As if I would flash a ftf?

yes whith this method you loose the Data, but you can also try to flash an FTF, which should have the same effect. You just have to set some Files to the state bevore rooting or wait till you get the Update via PC Companion or update Service. I think the best way for you is to wait till PC Companion shows you the update.

How should I restore to stock/factory reset for repair?

I'm wondering if there's a clear and fully working tutorial on how to unroot and restore a Sony Ericsson Xperia Mini Pro SK17a to stock so I can send the phone off for repair.
This is what I have so far:
UnRoot the phone using the ZergRush Exploit
Plug in phone and use PCCompanion and use the repair option.
I don't think I can so a Factory Reset on the phone since some stock apps were removed after root.
So has anyone else restored to stock after root and succeeded and is this the right way to do this?
Thanks.

Just use Sony Update Service and re-install the firmware with wipe data ticked.
OR
flash ftf file through flashtool with wipe data ticked ofcourse.
You don't even have to unroot because following any of the two methods above will automatically remove root access

Thank you for this, I was just making sure if I will do it right. I'll still unroot for additional "safety" since Sony Mobile's unlocked bootloader dispute, of course I didn't unlock it, yet.

[Q] 4.3 OTA update issue. Help!

Hi guys,
I have searched the forums for the answer to this but without success.
I bought my Z ultra (C6802) a few months ago. Rooted it using Kingo and updated to 14.1.B.2.257 and everything was fine so I was happy. My Bootloader is still locked however I have root.
Now a few weeks back I've seen an OTA flash up offering the 14.2.A.0.290 (4.3) update. I finally decided I'd go with the OTA update, however after trying to let it do its thing, it doesn't upgrade properly and after rebooting etc gives me an error saying "Could not install new software update. Try again."
I have tried a couple of things to get this working:
1. Tried clearing the data for update centre and redownloading.
2. Tried temp unrooting using OTA rootkeeper.
Neither of these make any difference.
I think after rooting that I uninstalled a couple of default Sony apps that were no longer needed (very carefully). Could this be the reason for the OTA failing?
Any suggestions?
Thanks in advance.
You have to update using PC Companion. You'll lose root though, but you'd lose that either way, so just update through PCC and root it again.

before updating back up the TA partition
as @LordManhattan said you will lose root though. if you want to keep a locked BL you cant get root using the PCC way, you have to flash FTFs and recoveries etc, see the thread in the general section for locked BL
YES. Backup your TA partition!
Ok thanks for the responses guys. I've already backed up my TA partition before, but will try flashing using PC companion later.

The OTA may or may not work, if it fails then just flash an FTF (with or without data wipe depending on your mood) and then reroot etc
Need help

Restoring my Z Ultra to stock

I unlocked the bootloader and rooted my Z Ultra (c6806) some time ago. I now want to return it to stock so that it can received regular updates from Sony. Unfortunately, I haven't done any rooting in a long while, and I want to make sure I don't brick the phone, etc. Is there a simple guide for bringing it back to a stock state where it can receive normal OTA (or PC Companion) updates? As of now, attempting to update returns this error message:
Problem: The phone/tablet contains modified software that cannot be updated.
Details: Sony Update Engine Failure (error 2003).

I apologize for what seems like such a silly question. Thanks for the help.
Have you locked your bootloader? If not then I'm afraid PC Companion won't do much for you. You have to either lock your bootloader and use PC Companion again or download FlashTool and a firmware you like, then flash it.

The bootloader is unlocked, and I have not relocked it. My questions are these. I looked around the site and I found these instructions:
Back to Stock:
To get back to pure stock Sony there are several things that need to be done:
1. Make sure you have root
2. Backup any data/photos/etc on the phone
3. Restore your TA backup with the TA backup tool above
If you are on a custom kernel or ROM you ZU will not boot at this stage
4. Start flashtool and load a FTF
5. Start the flash and wait for the onscreen instructions to connect the ZU
6. Connect your ZU in flashmode
With the ZU powered off
Connect to PC while holding the volume down key
Flash will start
7. Wait for flash to complete
My questions:
I did make a TA Backup, and I have it. If I don't restore the TA Backup (which seems like a little bit of a hassle), will I still be able to update through PC Companion?
If I just relock the boatloader, will I be able to use PC Companion to update from where it sits currently (I think 4.4.2)? Will relocking the bootloader on a rooted 4.4.2 device mess it up?
If I relock the bootloader, and I am able to use PC Companion to update, I will lose root, correct? And if I lose root, I will not be able to restore the TA backup, correct, unless I reroot it?
Here's my end goal. I just want the new stock Lollipop on it, and I want to be able to receive updates (they don't have to be OTA) from Sony. I gave the phone to my mom, and I want to keep it up to date. What is the easiest (and safest, least-likely-to-brick) way of accomplishing this?
Thank you for any help.

[Q] ABOUT root

Hey everybody
I know this will be stupid question
But now am on stock .28 rooted
If I got an update I can update normally using update center?
Or I have to unroot??
Thanks.
You can't update if you have rooted your phone.
OTA updates will be denied because of the modifications you have made. You will get a "could not verify" error
But if you force the update via PC Companion you will loose root, recovery and all the apps that need root such as xposed framework will stop working
Its not a problem to lose the root
But if I updated via PC companion it will update my android?

Why don't u update through flashtools ?
You'll find your desired firmware in its Database
Link: http://www.flashtool.net/downloads.php
Be aware: Your internal storage will be wiped.
With the flashtool I need the ftf file to flash
Then I dont wanna lose any data

You won't loose any data if you upgrade. Downgrades need all the wipes; updates no. And PC Companion may or may not work because sometimes it will deny updates to modified devices.
