[Q] Backed Up TA: is the File Valid? - Sony Xperia Z Ultra

Hi all,
I just want to make sure that my backed up TA is not a false file. I am afraid if i can't restore my TA backup after unlocking my bootloader.. :fingers-crossed: Please see the attachment and tell me that it's a valid one. For information, it was created when i Vrooted the phone on Android 4.2.2 (v.532 to be exact)
PS: Is it possible that i can unlock Bootloader, put a rootable Kernel to root, and then relock bootloader with this TA file? The First two steps, i am sure that it will work with provided steps here, only the last step (to lock bootloader) that i still have some doubts. Thanks a bunch.

The size looks right, and a backup from the 532 days is still valid.
And no, you can't do that. You'll softbrick since you'll be on a custom kernel. It should work (in theory) if you flash a stick kernel first.

You have misunderstood. A TA backup from [the days of] .532 will still work on the new firmware.

Ah silly me yeah i didn't see any dot before the number so i thought otherwise. Thanks Btw, i haven't run fastboot for a while (like, Xperia Rays days), but how to backup current stock kernel? Or do i need to extract kernel from the stock ftf then?

When u would like to reflash stock kernel, just use flashtool and ftf with fw which kernel u want and exclide everything but kernel

[Q] I need a lot of advice... thanks for looking

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?

so there will be some ROM's that don't require an unlocked bootloader??
Why are not all ROM's like this, then x-reality / track ID's would not be a problem...

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)

[Q] Restoring phone to stock

Hi everyone, wonder if you can point me in the right direction.
I'm currently on a custom rom with an unlocked bootloader and I wish to go back to stock including locking the bootloader, from what I've found out so far this is what I need to do: -
Flash original ftf
root
flash TA
reflash ftf to lose root
Now back to stock with "Bootloader Unlock Allowed: Yes"
Trouble is I can't find how to go about restoring the TA partition from my TA image so if anyone can explain what software I need and the steps I have to take I'd greatly appreciate it, thanks.
You can use the same tool that is used to backup the TA partition (read the FAQ in the 1st post):

I didn't know that you see as I used the Doomlord root exploit before the other methods were available, thanks again.
Edit: Thanks again, I'm now back to stock with the service page reporting "Bootloader Unlock Allowed: Yes"

Sorry for high-jacking this thread, it however loosely fits my problem.
When I got the Z2 I was, in all honesty quite quick with rooting and swapping the stock Sony ROM with Cyanogen. So quick in fact that I didn't bother for two seconds to actually perform a backup of the system beforehand.
So my question is this - is it possible (given the fact that DRM and such will be lost for all eternity) to revert to stock rom without the backup?
If so... How really? (couldn't find anyhone so stupid on here to do the same rookie misstake as I did so no answers was found while scouring through the forums...)
Thanks in advance, and yet again, sorry for high-jacking the thread.

you can revert to stock using flashtool and a ftf of your choice, also you can use flashtool to relock your bootloader
your drm keys wont come back

nothing is affected by your drm keys weather they exist or not in 4.4.2/4.4.4 xperias they are simply used to check if you have modified your device ie. bootloader unlock (relocking doesnt restore your drm keys)

Well as I already figured that I messed up any warranty, that's no issue for me, so really thank you. I was hoping that I could restore to original stock rom to be able to properly use the camera and noise-canceling headphones. Seems like it then. :good:

[Q] How to enable OTA updates again?

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.

[SOLVED] Root Access 4.4.4

Hey guys im back after smashing my beloved xperia z (which i had mastered the ins and outs of) and reluctantly replacing it with a HTC ONE m7 which was the most terrible phone i have ever used in my life.... i have plonked a good bit of cash on a z2 and I AM LOVING IT
I had updated to the latest version of KK but i am hearing mixed reports that a root is not available for this version.
If anyone could point me in the right direction that would be fabulous.
Thank you in advance

Hello
I see you are totally green on this.
Well, im kinda green too, but I have had a lot of help from @xda and now I can manage to do some stuff with my telephone.
The first thing you have to do is BACKUP!!! This is always important.
Well, then lets get to it.
The XPERIA Z2 has a locked bootloader. This means that it cannot flash any roms, custom or other without being unlocked. When you unlock the bootloader, you delete all files on the phone, (don’t ask me how, it just does) and also deletes a partition called TA. The TA-partition contains DRM-keys, to explain that, @Envious_Data might help.
Anyway, when you have root, you can backup the TA, BEFORE you flash any custom ROM, or the ROM with ROOT. That way you will always be able to go back to scratch. Without ROOT on 4.4.4 you need to downgrade to 4.4.3, ROOT and backup the TA-partition before you even start thinking about unlocking bootloader.
(search the XDA, Google (use XDA in the end for XDA results) XDA-TV and you will find tons and tons of stuff. Once you understand some, it will come fast to you.)
I have gathered some threads here for you to read, and I hope this will work for you too.
Start off by reading this
When done, notify me.
All the best

Have had some problems with SuperSU too, but try backup ta.
If not work, try restore phone with PCC.

Also, no need to backup TA unless you wanna unlock your bootloader

Backup of TA was just a mention. Also its smart to have it, cuz you might forget it.
Anyway, @xeningti the towelroot should work on 4.4.3, did you try to download the towelroot app from towelroot.com???

Did your phone come with 4.4.4??
Try root with towel on 4.4.3
Send some shots of it.

[Q]how can I restore drm functions without backing up TA in the first place?

Hi guys , so I wanna relock my boot loader and I thought locking it alone will automatically restore DRM keys but according to what I read it doesnt , and I really didnt know about this before unlocking so how can I restore those functions like VIVID mode and stuff when I relock my bootloader ?
thanks

Check the cross-device development section, there is a thread about DRM function restoration.

No. But you can skip the booting of the .69 firmware(just turn on the phone, see the Sony logo and force shut down(volup+power)). Then flash your desired lollipop firmware and !EXCLUDE TA partition! It is the most important part.

In flashtool, when you select the lollipop firmware, there is a list Exclude on the right. In that list check TA.
Simplified instuctions:
1. flash stock lollipop with flashtool
2. lock bootloader with flashtool
3. flash .69(turn on the phone and force turn off(if you get stuck in Sony logo) )
4. unlock the bootloader now
5. flash lollipop without TA
6. flash Androplus kernel to gain recovery
7. flash the DRM Restoration.zip from recovery and wipe dalvik cache
8. Done
Hit Thanks, if I helped!

If you saved your DRM keys before unlocking the bootloader, you can get it in its original state. If you didn't, you have to stay unlocked (or lock and lose drm functions, which I guess is not an option). But I don't see a reason for locking it. You can flash different kernels that way. For example, Androplus kernel have undervolting. It can reduce the heat of your device. It also has so many different options(governors, overclock, KSM, hotplug, etc.)

Install any .69 ftf you want. Just make sure it is for your variant of device (XX02, XX03 etc.) You will be overwriting it anyways. Just make sure it has a TA partition inside. If you don't see it, download another one.

Are you sure? The exclude list is scrollable. It should be there.
BTW Did you download the Orange-branded one?

Search for the Taiwan version on google. I got one of my .69 ftfs that way. The other one is from Orange, but the link is down.

Find a really dark place(behind the fridge, bed or something) and take a photo. There shouldn't be any green/red artifacts.
