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.

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

As the title says, I'm currently rooted and using the original .532 firmware.
What is the simplest way of upgrading to the latest update keeping root intact?
I'm able to update via wi-fi or over the air.
I read somewhere about rootkeeper?
Please could someone advise me on how to do this without wiping data and root.
Thanks xda members.

Thanks for the link. However, is there not an alternative & quicker method?
A user claims to have updated ota without losing root only by using rootkeeper.
I don´t know, but that method is quick and easy.
You must have the bootloader unlocked, do not have recovery installed, only change the build.prop with rooy explorer (you can try without changing it), keep the root with rootkeeper and update with sony update center.
You can try it with your original 532, I think.
rooted and on original software (condensed from http://forum.xda-developers.com/showthread.php?t=2502185). You do not need unlocked bootloader for this.
1. OTA Rootkeeper - install and protect root
2. Perform OTA to 257
3. Enjoy
If OTA fails
1. TiBu - make full backup of your apps & necessary system apps (wifi locations, SMS, etc)
2. FlashTool - Reinstall 532 FTF
3. Root (vRoot is suspect, but go ahead if you like living dangerously, we all do)
4. OTA Rootkeeper - install and protect root
5. Perform OTA to 257
6. Restore Apps via TiBu
7. Enjoy
* Of course, if you're doing it via OTA failure method, you should make sure all your app config files are exported out and saved (Nova, LightFlow, etc)
hey dude do nothing. do not unlock bootloader or anything else. if you have root just ota thats it no need for a rootkeeper or anything else.
can it be any simple than that???

That's what I did last time but root was lost.
I may skip the update and wait for Kitkat 4.4 and root.
I noticed no difference or improvement whatsoever when I had 257.

hmmmm it worked for me tough.
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.

Hi,
I have a UK unbranded xperia z2 and just received notification that there is new firmware.
It says I can download it via wifi without connecting to a PC.
I have previously rooted the device without unlocking the bootloader. I am wondering - if I update the firmware over wifi will I lose root?
If so is rooting it again as easy as it was the first time? I think the first time I used easy rooter app
Thanks

Yes and Yes, you will loose root but rooting with your favourite root exploit should be identical procedure.

I just tried OTA update and it said it "could not verify" - after some research seems I have to remove root. But I dont want to have to wipe my phones data.
Is there a way to remove root without wiping data? In superSU, there is a "Full Unroot" option but will this actually remove root so I can update?
Flash the unbranded ftf for 314 UK, via flashtool, specifying no wipe for data and you should be OK although you'll have to reroot afterwards.

OTA update generally removes root. But you should be able to root again with the same procedure. The full unroot option in SuperSU does actually what it says and will fully unroot your device allowing you to update the firmware.
Just give it a try.
Hit thanks if it helped
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
