You can't via pcc or sus, you need to use flashtool to flash roms or recovery to install updates and keep root.

Use flashtool to flash latest firmware, you can find flashtool and latest firmware ftf file on development section.

What specific error?
can you update ota if you're rooted? i thought i read somewhere that you can't? or is that only if you are unlocked bl?
For convenience/less errors it is highly recommended to have a fresh firmware. No root, locked bootloader. For you to update via OTA, Sony Update Service, or PC Companion.
When the BlueBox appear after download and restart the phone The phone restart again and appears a Box saying there was a problem, try again

Have you tried using PC companion or SUS?
just to confirm that you CAN update a rooted LT26i.
just use PCC or SUS
its all good.
p.s for some reason the size of the OTA update download is much smaller that the update download done by PCC/SUS (almost 400MB) maybe this why many have complained it doesn't work.
For me it makes no difference OTA or via PC, both are failing. I have an unlocked bootloader with that Swiss ICS rom which was published around 20th of June, a few days after the ICS release. ( LT26_6.1.A.0.452_Generic_CH_1257-3740_.ftf )
Could that be a reason for the update to fail?

You can't update with unlocked boot loader on those programs. Use flash tool.

Got a ota updatw to 4.3 but halfway intalling ota, it would just stop. Please advice. I am on a sim free with a lock bootloader.

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...

- Unlock the bootloader
- Flash 290
- Flash modified kernel via fastboot
- DO NOT relock the bootloader, the phone won't boot otherwhise.
I need some help to install recovery of my rooted Sony Xperia Tablet Z SGP 321. I am currently running build 10.5.A.0.230 and I think the bootloader is still locked. I have rooted using towelroot. And I want to continue with stock rom but need a recovery for this. Any help or link please.

Today there is a notification for system update from Sony. Can I update after root?

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).
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

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 have updated through PCC, never a problem. Here in the US.

Are you on unlocked bootloader?

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
