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.

So I just got my phone and noticed the volume playing music was a little low. I installed this mod and now I have no sound! I can't play YouTube anymore either, it says a problem while playing. I tried to restore my original file and it didn't work. I factory reset it and still no change. I'm rooted but on stock and still have a locked bootloader. I would love to just start over but I think you have to unlock the bootloader, which I really didn't want to do. I wish I could just go back to stock and update up to 4.4.4. Any suggestions?

Does anyone know of a way to make the volume louder? My Note plays stuff much louder than this and I would like to boost the sound a bit. The clearboost (?) didn't help much. I would also like to remove that loud noise can damage your hearing warning, but right now I'm just happy with having sound back!
Yes to flash the 4.4.2 full OTA (modified) you will have to be on an unlocked kernel. If all else fails then follow these steps (all in the [Guide] thread in the GPe section):
Back up the TA with TAbackup
Unlock BL
Flash or hotboot DooMLoRD's advanced kernel or DooMKernel
Use custom recovery in new kernel to flash the modified 4.4.2 OTA (link is in guide I think)
Restore TA (this will relock BL)
Follow OTA updates back to 4.4.4
Root with towelroot
You should now be back to where you started

Oh okay so the only way to fix this is with the unlocked bootloader? I'm trying to do Doomlords adb sideload but its difficult getting my computer to even recognize the adb commands. I was hesitant about unlocking because I remember reading broken cameras with the updates.

So I've been reading and I really don't feel comfortable unlocking my bootloader. It doesn't help that when I go to BackupTA it just hangs at waiting for debugging, even when it tells me on the screen debugging is running. Is there a flashable 4.4.4 zip for this phone? I saw one but it was for the regular Ultra and I tried to flash the 4.4.2 but it wouldn't let me downgrade. I'm really stumped! I can't believe this one little hack completely ruined my device!

Thank you but that didn't work. Neither did me restoring my old mixer_path. I'm at my wit's end here, I'll probably just send it back and get another one.
I was looking for a whole 4.4.4 flashable rom that's stock, but I can't find it anywhere, just the OTA incremental zip. I was just going to flash that and do a factory reset, but I can't find a zip that will install! I would consider myself pretty smart but I'm genuinely stumped here.
Thanks for the mixer_ though

none of the incremental ota will install on to anything than what they are meant for. The 4.4.2 full ota can be installed from a custom recovery as I've said, and if you do it correctly there will be no difference to a new one.
I missed a step or 2 above though:
Back up the TA with TAbackup
Unlock BL
Flash or hotboot DooMLoRD's advanced kernel or DooMKernel
Boot into recovery
Use custom recovery in new kernel to flash the modified 4.4.2 OTA (link is in guide I think)
Gain root (hotboot doomlords advanced stock kernel and flash supersu from recovery)
Reboot
Restore TA (this will relock BL)
Follow OTA updates back to 4.4.4

Good day sir,got a question,so how did you get back the audio and play video to work?
To get back to stock 4.4.4 u can unlock bootloader and fastboot the system.img from this thread http://forum.xda-developers.com/showthread.php?t=2799423
Hi!
I have the SGP311 with the 4.2.2 Version of Android. Back then I rooted it using the tool VRoot (i think that was the name).
As all I wanted was root for TiBackup I left it at that. Stock ROM, some modifications through root access, but I saw no need to go further.
I would now like to update. OTA does not work, either because I am root or because the bootloader unlock (which I think happened during the root process).
There are so many guides out there, some contradictory or rather relying on going from certain versions to the newest.
What is my best bet?
Unroot and Relock, OTA update, then re-root? Is there a Guide to that?
Or how do I get a recovery on there easily? Guide?
Then assuming I have recovery on, what do I flash. Sony has grown on me, so I am happy with a stock rom or something very close to it, if I can root it for my mods.
What is the least dangerous way to get this tablet up to date?
Thanks for your help!

Vroot would not have unlocked the tablet's boot loader, so are you sure it is unlocked? And have you tried using Sony PC Companion to update the firmware? I was going to recommend trying to use Sony Mobile Update Service, which I preferred over PC Companion, but it appears Sony stopped supporting it.
Hi everyone, I'm quite new at this and don't want to slip up. Every other solution for this has been sending me in circles and I need some help.
So I've got a Sony Xperia Z2, that's on 23.0.1.A.0.167 (4.4.4) at the moment, it's Australia Optus firmware. I had root on 4.4.2 on a locked bootloader, using the one-click method. I used PC Companion to update and lost root, as I expected. I've really been missing it. How (in very simple terms, I'm not too experienced) do I root this firmware, without unlocking my bootloader and without losing my data any step of the way? Is it possible? Those are the only 2 requirements, anything else is fine.
Thanks in advance, Dean.
1. Search - this has been answered many many times,
2. backup your data,
3. Downgrade to 4.4.2,
4. Root and install recovery,
5. Install rooted 4.4.4 zip in recovery.

Sorry to be a nuisance, I was getting confused at those threads. So I have to back up my data all manually right? Thanks for the help.
Okay,I posted recently about my old z ultra. I bought the z ultra off Craigslist and it was updated to 5.0.
Anyhow the screen got the dreaded 'hairline' Crack in the screen and Sony covered it.
They sent me a new phone international version and the first thing I checked were the hidden functions in the dialer. Rooting status says yes or bootloader rather. Also the phone is still running 4.3. I did some searching and found a root method. I don't want kingroot or any Chinese crap.
Do I need a computer? Can I root using towelroot? Install busboy? DL cwm and flash via the phone?

Nope. Towelroot does not work on 4.3. I hope my phone doesn't force a system update. I'm still 4.3 for now.
Not a gpe edition either
Screw it. I think I'll just take the update
This is why im tempted to multi post. A moderator warned against multi post. Ive had this post up for a few days now and ive not got one answer.
I need to know about 4.3 jellybean. My phone was shipped with it. Do i have to use flashtool? Whats the first step? I haven't taken the update. Im still 4.3
PLEASE ANSWER
Hello there lonely islander! I'm randomly passing through with my ship, and I caught your smoke signals.
I can't really remember the root situation on 4.3, but there were quite a few rooting tools in the cross-development section. Not sure if those were for 4.1 or 4.3 though. I'll do some digging and I'll be back.
What's the firmware version? .290?
EDIT: Okay, so I've done some searching, and this method was the one that people used back on 4.3. It's not perfect though since it required the use of Vroot, which is/was the same type of rooting tool as Kingroot, so that's probably a no-go.
Another way of doing it would be to downgrade to a firmware that's supported by towelroot. That would be 4.1? 4.2? Find out which version is compatible and find that firmware FTF in the Dev section. You'll probably have to do some digging since a 4.x ROM thread will be quite old. Flash it using Flashtool and then root with towelroot.
But...
What's your plan now? Backup the TA partition (DRM-files) and then unlocking the bootloader, update to 5.1.1 and easily root again through fastboot since your B/L is unlocked? Or are you planning to keep the bootloader locked and live the rest of your life on an ancient Android version?
EDIT 2: Have you tried this tool on 4.3? It's based on Towelroot, but it's customized for rooting Xperia devices. I think that maybe, probably, it'll work on 4.3. I don't know, so go ahead and just try it unless you've already done it.
EDIT 3: Okay, so it looks like the tool provided in "Edit 2" should be compatible with Android versions up to 4.4.2 before being patched by Google/Sony in 4.4.3/4.4.4 (KitKat), so it should in theory work on 4.3.
EDIT 4: OKay, I have no idea what's real anymore. I just stumbled upon this post from that thread:
v 12.4 worked like a charm on my Xperia Z Ultra C6802 (4.4.4).
Did TA backup. Installed SU chainfire and updated binary in normal mode. Got write to external SD card ability on my Total Commander without any SDFix app. Thanks.

So... just go ahead and try it. If it fails, then you can downgrade using Flashtool if you're into that.
Build is 136. No,you are correct. King root is king crap. Im not going back there. The bootloader status says yes. Will i have to use the sony web site to unlock bootloader? Yes, i want root and i want too flash roms.
So,can i just root and install safestrap,superSU or do i have to unlock BL.
I could update to 4.4.....
Okay. Forget what i want. Tell me the steps i need to take. Im on 4.3. Build136. Yes i wanna root and i wanna rom..

Alright. First step is to test and see if that root tool I linked to in my previous post works. If it does, great. If it doesn't, it'll get a little more time consuming.
But the important question here is: Do you care about the DRM files? They control mostly the camera which will be a little affected by the loss of the keys. It'll happen either way when you unlock the bootloader, but backing them up allows you to restore them later if you ever re-lock the bootloader for some reason.
So you can either:
1. Backup the DRM files, but doing that requires root, which is fairly hard to obtain with a locked bootloader, which you are currently witnessing.
2. Ignore the loss of the DRM files and unlock the bootloader right now. When you have unlocked the bootloader it'll allow you to boot and flash custom code, like a custom kernel with recovery (CWM/TWRP/Philz) which again allows you to flash SuperSU and be done with it, or flash a different ROM. It's the easiest way, but you'll lose the DRM keys. They might become handy if you have to send your device in for repairs down the road (if you have any warranty left, that is)
So what you need to decide right now is what you want to do.
Should i update? the next update is 4.4.2. I could take it then use watevr roottool. So root first then unlock bootloader

No, just try the root tool right now while you're on 4.3. If it works, it works.
Did it work?
Im going to attempt here in a min
But first my good man,in what order do i do this?
Root first,unlock BL,install recovery?
Root bootloader status says yes..do i need to mess with it?
I updated to 4.4.2. Towelroot does not work on any of them

Alright, now we know.
If bootloader status says YES on unlocked, then it's already unlocked, and we've wasted a bunch of time! If it's already unlocked, then just install recovery.
Bootloader unlock allowed:yes...... So i take it,its not.
Can i use flashtool? I tried sony "official " way and i did NOT understand it. So ive read into flashtool and it seems easier.
If i get a recovery on this thing im good from there.
I dont understand the steps. On Samsung note devices its root,safestrap, SU then happy flashhing.
This device is crazy confusion

OK. Here is what you need to know and do.
1- you didn't need to upgrade. A towelroot variant would have worked.
2- you don't need to unlock bootloader.
3- you need to install, from a PC onto your phone, what's called Xzdualrecovery, which is essentially a recovery. Google it and download the latest installer for this phone. You need to enable USB debugging on the phone so it can be installed from the PC. When your start the installer there is an option to instal AND root. This tool comes with the variant of towelroot tha can properly root your phone, if your OS date is before June 7 2014.
If you need help with these steps message me.
Thank u najoor. I have only updated to 4.4.2. I tried towelroot. Didnt work. I have a c6802. So im completely stock and your saying theres a tool out there that can root and install recovery from a pc.
Flashtool? Could you provide a link?
