Update via OTA - UB and root - Xperia Z Q&A, Help & Troubleshooting

If i have UB and root can i update my phone via OTA? Or should i unroot and then i will be able to update?

I don't think you can do OTA update on UB.

And on root. I can't update OTA rooted phone...

4.2.2 OTA to 4.3 ? Root preservation ?

Hi all,
I have a few questions that burn me. Just received the OTA notification that .569 is available (304.4 MB)
I am running .67 with stock recovery, root and phone encryption. Will those be preserved if i OTA update ?

AFAIK root is lost and recovery is rewritten. I don't use phone encryption but I guess it is ok (or it would be stupid of Sony).
My experience has always been that OTA updates break root, and most of the time you wont be able to get it back until there is an exploit for the new firmware
4.3 OTA update will take away root and you will be unable to root under 4.3 directly.
You have to use the root methods shown as below(root under 4.2-flash another recovery-flash pre-root 4.3).

OTA left my root as it is. Check my post, how I did it:

This was the first OTA that broke my root, even with supersu in survival mode.
I updated ota from 4.2 to 4.3 and kept root.

I tried the OTA on my rooted C5303:
Setup stops after reboot: not possible to install new software, please retry..
Keep 12.1.A.0.266 - It looks like OTA is not possible on rooted phones (like in the past)

[q] 14.4.a.0.108 ota

How big is that OTA update?
Try, if you can flash it it could work and you could actually preserve root, maybe even recovery but in 99% of cases you'll get error.
OTA update can't be flashed on rooted device (but, as I said, there were few times it actually worked if it's small, few mb update)
But this is update from 4.4.2 to 4.4.4 so I doubt it'll work.

OTA updates with root are fine, but you may well lose root, just as you would flashing a FTF or updating via Pccompanion.
The issue with OTA updates is if you have an unlocked bootloader.

That's not correct mate.
Try to downgrade, root and install recovery then try to update via OTA - you'll fail.
Only one or two OTA updates worked on rooted Z1.
I have rooted Z1 with locked bootloader and OTA will always said - error while trying to flash, update your device through pc companion.
I'm 100% certain...

OK, the few times I tried it I had no problem, but I have only ever done it a couple of times..
It's 154.5 Mb, my bootloader is still locked only my device is rooted so I will go ahead give it a try and see what happens if it fails or I lose the root I can again downgrade and root right?
Yes, but you can also just root the FW anyway

If you want to update, then download FTF. You will loose root. Or use NUTS pre rooted rom. If you want to root yourself, look over to cross development and use easy root tool v8. Then also download nuts xzdual for locked boot.

Does upgrading to 5.1.1 OTA cause root access loss

I am currently on lollipop 5.0.2 and rooted and I got ota update notification. Does upgrading ota leads to root access loss. And how is this update treating you?
Yes, just root via methods shown elsewhere or own preferred method ..... It's great.
