I rooted my phone and then updated it with OTA update, and after that I had full root access, it didn't remove my root and didn't brick my device. But it was with my old phone (Xperia S), not with my Z2. I haven't rooted my Z2 yet

You might loose root with the update. It is possible that with a minor update you keep it, but with any major update you will loose it. However, you device should not be bricked unless you have an unlocked bootloader. In case you have an unlocked bootloader, do NOT update via ota.

[Q] Rooted Will I Still B Able To Update to 2.1 the Regular Way?

What I mean is that, now I have rooted, will I always have to update to newer versions via this forum or will it update via SE Update service as it would have done before I rooted?
Cheers
Yea 100% sure you will be able to get all updates . rooting doesnt prevent you from getting updates . when your phone will get updates you will just lose the root since new update is being installed and old one is gone.So go ahead and root it

updating to 2.1-unroot?

When the 2.1 update finally comes will i have to unroot my phone to update it?
No, you do not need to do so.

[Q] Keep root OTA 14.1.B.2.257

Hi,
I could only find people asking for rooting 14.1.B.2.257, but no statement if root is kept if I simply update an already rooted device.
Do I need Rootkeeper, will it just stay rooted without me taking additional steps or is it currently not possible to keep root?
Regards,

Yes, as long as you update OTA (Over The Air) and not through PC Companion. Change the CDA to a country that has received the OTA.
Alright. I don't need to change the CDA (whatever this is), my phone is already telling me to update for a few days.
Am I doing something wrong? The Update always fails after a few seconds. I rooted using vRoot and the only change I made was switching the boot animation which I already tried to replace with the original one.
I too have the same problem with OTA update. i'm rooted nothing else it downloads then goes into installation but it doesn't and it tells me that I couldn't install. any idea guys. is vroot working on .257 yet..?

Hi,
There seems to be the same conversation over a few similar threads...
Anyway, I also am in the same situation.
I received the OTA, so I installed Voodoo OTA keeper and tried to install the update.
C6802, originally HK, changed buildprop to Vietnam over 2 months ago.. updated a few times and have been using this .532 for a while now.
As you describe, after download of update, start the update procedure, phone reboots in update mode, but after about 5 seconds, it reboots again into the normal boot mode and sequences, failing the update.
I know connecting it to the PC Companion and upgrading it would solve the update error, but my main interest, as yours probably is too, is to keep the root, so that there is no hassle of having to unlock the bootloader and flashing backwards and forwards...
My .532 Vietnam firmware is too good (with root) to think about updating, because short of this update bringing increased battery life that is purely amazing, it will not bring any benefits to me. I am one of those lucky ones with no screen issues what so ever..

I also have what you describe, but even updating via the PC Companion did not help. But it seems keeping root is a little tricky and I have no screen issues either, so I think I will just hold off on this update...
I also have the same problem (failed ota update)

I have the same problem. v14.1.B.1.510 but the OTA downloads, switches off the phone, tries to install but fails. I've used vRoot to get rooted as soon as I unboxed this phone. so does this mean I can't update, ever??

I can't guarantee this will work but try to temporarily un-root the phone with Voodoo OTA Rootkeeper.
Unroot with voodoo didn't work

Try to unroot from the SuperSU app.
Unroot with superSU didn't work either. the Unroot worked but not in the way this OTA needs, it appears

Android 4.4.4 update help

Hi guys. I just got the ota update for the KitKat .167 firmware. I tried updating. The first time it started the process got half way then the phone restarted. The phone did not update. Then I tried a few times again it said could not install. Now I get could not verify. I'm locked bootloader unrooted on .314 firmware. I was previously rooted for like a day and then unrooted. I'm on O2 UK

You have to undo any mods done with root and anything else changed using root
I recomend updating using flashtool and a FTF of choice if you mod or use root stuffs
No need for verify

Rooted Pixel Experience OTAs

Running latest Pixel Experience w/ root right now and was wondering about OTAs.
When updating, is there anything I need to do with root or can I just run the OTA normally and update?
Last time I ran an OTA update w/ root, my phone would restart randomly sometimes during usage and I couldn't figure out why so I reflashed everything and it hasn't happened since.
Leads me to asking whether updating while still rooted messed with the phone in some way. So yeah, do I need to unroot before running the OTA or do I unroot and then OTA and then reroot?
(Also, if I need to unroot, how do I do that? Have only ever rooted phones, never had to unroot one.)
