Hi guys,
i have found a few threads with same question but for other handsets so making sure to do it right.
I have got a C6833 which i rooted, unlocked bootloader and flashed custom rom. I need to send it in for repair because of some speaker issues and would like to return the device to original condition. I have flashed a Sony ROM with flashtool but obviously that was not enough, the OTA updates don't work so i assume something else is wrong.
WHat do i need to do to fully restore it? Also, what is the newest stock rom for an Australian handset?
Thanks a lot, i am sure this has been asked already but i couldn't find the answers needed.

You must relock boot loader. Dont forget your ta back up as well. This is what I would do. Relock bl hook up to Sony pcc and repair the device. It will become factory.

Thanks for that. I do not have any back ups such as TA. Is there still a way to do it?

you can lock the BL with flashtool but they may still refuse warranty - some do, some places dont.

Hi people. This is my 3rd android device. Two samsung products, and now the Z ultra.
So I have no idea what people are talking about... I'm used to ODIN... so is flashtool a similar piece of software?
My xperia Z hasn't arrived yet, Im just trying to get my head around sony and the way their devices are run..
So.. questions...
1. Backup your TA partition (I read that this has important info that I don't want to loose... Do i do this with flashtool? Do i also reflash this partition at a later date?)
2. Unlock your bootloader (Why are some people not unlocking bootloader... Do I understand correctly that some features will stop working... like x-reality?? If so, can't they just be reactivated with a custom ROM?)
3. I see there is a recovery for locked bootloaders... (can you still flash kernel's custom ROM's zips using CWM with a locked bootloader?)
Ive spent 3 days looking on the threads here, but I think because of my previous devices I have a preconceived idea of what i should be doing.. I'm confused.

Now everyone knows you're a n00b!
First of all, the minus of unlocking bootloader is losing your DRM keys. To do this, sony has provided us an official way through their website (just google it). Or you can do this via flashtool too. After unlocking, you will lose xreality engine and won't get FW update from sony anymore through official means (pcc or ota, but you can always flash). Some says trackID will be lost, too, but hey, who use it anyway?
The plus is, you entered godmode for flashing anything into your phone.
Unlocked bootloader can be relocked through flashtool, but relocked is not the same as locked, because xreality is still lost, cmiiw. To restore to original locked state, use backupTA (search thread in xda) BEFORE unlocking bootloader. And backupTA needs root, so we need root w/o unlock bootloader first (already plenty in other threads).
And yeah, what a maze this is.

Ok thanks, that confirmed what i thought about bootloader..
Can you still flash VIA CWM with a locked bootloader?
otherwise as i understand it...
1) root device
2) backup TA parition
3) unlock bootloader
4) flash ROM/kernel/etc
5) reflash TA partition.
done... custom ROM with x-reality support?

Well it's harder to make, apparently. Currently even custom recovery for locked bootloader is not finished yet. Check the development section. And flashing things that normally isn't allowed on locked does have limitations, check in other xperia devices threads.

Actually on firmware .510 with unlocked bootloader and I still have Xreality. Making your Ta backup is mainly to be able to restore your device in case of softbrick or restore your phone to stock.

I am looking at getting the phone too. From what I understand is when your bootloader is locked, it will only load signed boot partitions. So any modification to the boot partition outside of the official stock kernel will not boot when locked. So installing any custom kernel (OC/UV/etc) with stock rom needs unlocked bootloader, or installing CM (which has it's own kernel anyway). So best is getting custom roms (only modified system) with stock kernel.
Also like already said, unlocked bootloader means no updates from Sony. I would backup TA at all costs anyway.
I doubt stock kernel supports kexec, but I guess you can hack the system init process to load different ramdisks. Which is why I guess they are having trouble with locked bootloaders with recovery ramdisks in the dev forum.
I am waiting for the C6806. Here are my plans:
1. Root using vroot (hope it doesn't infect TA with something ;o)
2. Backup TA Partition
3. Unlock
4. Deal with loss of DRM
5. Install whatever ROM/kernel for daily usage
6. (maybe make official TWRP)
7. Get official updates by restoring TA partition, stock kernel if necessary
or...
1. Root using vroot
2. Backup TA Paritition
3. Stick with stock kernel
4. Help with getting locked 2nd ramdisk working with stock init
5. Is the stock ROM awesome enough? (Not sure since we don't have 4.3 )
Also hoping info comes out about ATT bootloader soon on Note 3.
LTE phone is out by 9/25 I am thinking with US warranty support. (C6806)

hi All, good day. Sorry just a noob. Ive tried to read the whole thread and cant find an answer to the follwing questions. Hope you can help me.
1. Is there a posibillity of losing an network signal when flasing a custom Rom?
2. when i root my device, is there a posibility that the X-reality engine will not work properly?
3. ive read that the device can be rooted even if the bootloader is locked. If i decided to unroot it again, can we do that?
4. is there a flash counter in xperia devices just like in samsung where in you can see if the waranty has been breached already or not?
5. can we turn the device to its original state again after rooting, unlocking and flashing custom roms?
6. if device is rooted, can we still install new updates from Sony thru OTA?
thanks,
Have a great day!

Yes you can unroot just by flashing a Stock Sony ftf over the current one via flashtool. Preferably the same firmware( without wiping)
Also, there is no flash counter in Xperia. If you have a locked bootloader and it is unrooted, there is no way to tell if you have unlocked or rooted

No problems with NFC here.
There are different ftfs for different regions. But that's not a problem. You can flash any region's ftf for your specific model number. If your model is 6833, then download any .757 c6833 ftf and flash it. Have a nice day

$100.... it's sounds good? Okay from my experience I bought my XperiaZ from Australian Telco before and it said Bootloader unlock allowed:No
but when I flashed official generic ftf using flashtool. It's said Bootloader Unlock allowed:Yes. So if you can take a risk try it(do it by your own! and don't forget to back up!)... you might try to do that. Luckly my XperiaZ2 is bootloader allowed one. Hope I have a chance to get 100bucks

This is very dangrous, this depends on the contents of the FTF and i wouldent recoment this at al
Have you tried flashing the German DE generic FTF, i think it has stuff for the TA partition
This may do your job
I still dont recomend, do this at your own will if you know how to unbrick a device
Although i would try it but only because i know how to unbrick a xperia (lol this part usualy takes a while)

I noticed him that it must be done by his own.... But he asks us to is there are anyway to do that? so I just posted the way I did.
I am not recommending him to do that.... I just simply answered his question. Always flash ftf w/o TA and partition.
It is recommended everywhere and If once he started to searching about flash tool it is warned by everyone.
You can't back up TA partition w/o root. So I don't think there is any way to get XperiaZ2 to back to completely stock.
(Although i would try it but only because ←What does it mean? It doesn't make sense for me.)
Well, I tried to flash the stock FTF.. same version as my devices. It errored.. and I am now bricked.
You can't modify an FTF and flash it to a bootloader locked device, modifying it will break Sony's signature verification
I'm guessing there's no way to unbrick?

Unplug device totaly

You'll need to find Sony's signing key then. Good luck with that
Aww.... We warned you.... it must be done by your own and not recommended. Try SEUS.... (Not sure if it works for yours....
Everything what you've done with flashtool will be avoid your warranty..... I think when you downloaded flashtool they warned you again....
As EnviousData warned you too.... even I did not recommended to do that.... dear....

Honestly i say keep your $$$ and wait for a exploit or root method of sorts
Me and my FTF will be a while and Z2 Development has started very slow and may be a while before anything of the sorts comes avaliable
I suggest if you realy want to root try exchanging your device for an unlocked one (or unlockable :/)

Forgive me if this is stupid, its the only solution I have been able to come up with to my original issue (here if anyone has a better solution http://forum.xda-developers.com/showthread.php?t=2798335)
Because I cant access my recovery I need to flash a stock firmware to basically wipe the slate and start again. The only issue I have is that the only ftf file I can find for the UK is unbranded whilst my phone is locked on EE, if I was to flash the unbranded file will it play nicely or are things going to go from bad to worse? I would guess that it probably wouldn't work, but it there's no harm in checking.
so nobody knows the answer to this?

It should work but I think the SIM won't work. Then again, I don't know anything about locked carriers (Never had one).
If your bootloader is unlocked, try the EMMA service by Sony. It finds your phone's stock firmware if you're on a custom ROM with unlocked bootloader.

Hello everyone. Seriously need help here with a xperia z ultra c6883. I bought it off someone and tried to do an update from the phone but it keeps saying 14.3.A.0.757 could not verify. FYI, I checked to see if bootloader is locked and it says yes. I downloaded rootchecker and it says device not rooted. I dont know where to turn. i just want to be at stock.
android version says- 4.4.2
baseband version says -8974-AAAAANAZQ-10270045-39
kernel version says - 3.4.0-perf-g8c33725
[email protected] #1
build number says_ 14.3.A.0.681
What does this all mean? Am I rooted? Do I have an unlocked bootloader? Can I just go back to stock? Or is it easier to just upgrade to lollipop?
Try locking the boot loader and then connect to Sony PCC and redo the phone.

you can use flashtool (http://flashtool.net) to relock the bootloader, but if you download flashtool you may as well just use that to update the ZU to the latest FTF from here (see the FTF thread in the dev section)
Is there a how to video on the process? Ive read things like ( I need to know what rom im using or drm keys etc etc) Dont know what to do.

In the FTF thread there is a video
As you brought the ZU already bootloader unlocked the DRM keys are gone (unless the last owner still has the backup). Just flashing a FTF doesn't relock the bootloader, you have to use the BLU icon in flashtool. The BL does't have to be locked to flash a FTF but it does to get/use the updates directly from Sony.
Any more Q's just ask
Ok thank you for the info. If you dont mind I might hit you up tommorrow for more Q's.
