Hi there, ive came all the way here from the Defy turf and im really confused about flashing my new xperia z. ive tried my best reading the tutorials but it seems to be alot harder to flash the xperia z with proper backup, i mean i used to flash my Defy pretty much everyday without worrying much.
So my question is very basic.. btw I have root my xperia z through the "[Exploit by: goroh_kun & huhka_com]" method, and the bootloader is unlocked.
1. Is it possible to backup my unlocked stock Xperia Z with DRM & BE2? i know there are both twrp and cwm, but ive heard that once I "flash" my phone I will loose everything even with the SD card... (i mean when u talk about flash, there are tons of file types u can flash such as img, rar, zip etc and also tons of ways to flash, so which way to flash is the best without loosing eveything?)
And if yes, is there a step by step guide about how to use the flashtool? (i know there are million posts about what a flashtool is, but what i need is a step by step on how to install/flash cwm or twrp on an unlocked stock xperia z with DRM & BE2.) I mean I would like to be able restore if I dont like the custom roms.
2. does upgrading from the Sony update wipe out all data? i mean for the future 4.2 update can I just update without loosing from what I have at the moment (an unlocked and root stock xperia z)?
sorry to ask all these basic questions, but ive been searching alot with no clear answers...
thanks!:good:

uh bro. as soon as your bootloader is unlocked, DRM keys are GONE FOREVER. Unlocking your bootloader wipes everything too. by everything i mean your photos, music etc as well.
secondly, some updates might wipe data, and some don't

thanks for the reply. but i dont really understand, because I still have BE2 and track ID working, how do I check if I still have my DRM keys? i know i have an unlocked bootloader through *#*#7378423#*#* but i dont remember unlocking my phone apart from using the [Exploit by: goroh_kun & huhka_com] method to root my XZ. Can a XZ come unlocked from a Sony Retail store?

You're not confusing unlocked and unlockable are you?
The only way to unlock the bootloader that I'm aware of involves getting an unlock code emailed to you from Sony via their official unlocking website.
While the bootloader is unlocked you will not be able to update to a new official Sony ROM either OTA or via their provided PC/Mac software tools.
Locking & unlocking the bootloader is explained clearly here:
http://forum.xda-developers.com/showthread.php?t=2153261
The bootloader will be locked on all new, unopened XZs
regardless of place of purchase, a phone purchased from Sony will (should) be carrier unlocked however.

Now I get it, so I simply have a rooted locked (but unlockable) Xperia Z~
it looks like everything makes sense now:good:
Thanks so much!
just one more question, does twrp or cwm recovery backs up everything including drm keys BE2 and etc? or do I have to go through this? http://forum.xda-developers.com/showthread.php?t=2234627

nope, recoveries dont back up your drm keys.
you have to use the Backup TA tool that was posted, this one
http://forum.xda-developers.com/showthread.php?t=2234627
Remember, ALWAYS, MD5 sum check before flashing, flashing someone else's or corrupted TA will HARD BRICK your device,

Problems Solved
Hi,
I unlocked the bootloader and took a TA backup. I tried to flash the CM kernel, but could not do it as the instructions seemed too vague. Hence I wanted to go back to stock. So this is what i did.
I used the flash tool and flashed the stock ROM again. After that I restored the TA backup again. But I still see that my camera is not working. Hence wanted to know.
1. How to get the camera working after unlocking the bootloader ? Is flashing TA enough?
2. Will restoring the TA backup lock the bootloader again? If not, how to lock the bootloader again?

Also after flashing a custom rom (which needs unlocked bootloader), can i flash the TA partition to get the camera functionality?
No, as I said, restoring the TA relocks the boot loader, which means you can't boot a custom kernel. So any custom rom that needs a custom kernel will result in boot loops.

As Greg's already said flashing the TA file will restore you back to normal, which means that it's kind of pointless unlocking the bootloader as of yet, unless you can live without your camera, personally i can't.
Just root the device and flash Monx's rom, at least until someone fixes it (unlikely) or Sony release a new version of android and hopefully fix the issue with the camera, keep those TA back up's safe by the way, each one is unique so you couldn't borrow someone else's.

Oh sorry, yea its decent enough, ive got the kitkat launcher on it I find it better and the "Ok Google" is brilliant, strictly speaking you don't need a rom from here, having a stock rom will work as all the mods that you can get will come from xposed anyway.
Give it a whirl and see how you go, thats the best way to know with rom's m8 as some people just don't like what others do.

it is possible to lock it without a backup, is your camera not working anymore ?
You can try flashtool, BLU option tries to relock it if it's unlocked, theres a good chance you will brick your device!

Are you sure this is good and/or informative advice? I thought a locked bootloader not finding valid keys in the TA will refuse to ever function usefully again - no boot, no fastboot, no flashmode, nothing, totally bricked, and no way to convert it back to unlocked and get your phone back.
I would like to know if I am wrong about any of that. And... it seems that I was:
** Correction - it is Ok to relock the bootloader without having the pre-unlock data in the TA partition
** Flashing in data from any other TA partition (some other phone) seems certain to brick the phone though.

I've never read about those damages but I read things like the known camera bug.
I unlocked my Z1 on .290 - the Sony release which fixed the problem (4.3). I flashed a Recovery and rooted it with it and my device is working like it was with a "untouched" ROM.
That's all I know.
We could wait for a dev to answer deeper questions.

Yes this absolutely fine and is what I did with my Z1, ie do not unlock until after the 290 update is applied - you will see that advice on the Sony unlock website. However if you want a TA backup you need to do that before unlocking as the unlock process will wipe the keys, and you also need root in order to make that copy. (let me know if I am wrong about that)
My process was to root on earlier firmware, copy the TA, update to .290, then unlock. After unlocking full root on .290 is easy with a custom kernel and everything is good: unlocked, rooted *and* working camera.
But you *will* need a copy of the pre-unlock TA partition to regain any of the functions that use the DRM keys if you decide to relock the bootloader later.
It is impossible to get the DRM keys back, and there is no gain from relocking without them, all you're doing is locking down the bootloader without enabling BIONZ, etc, but you can certainly run a stock system if you want.

Hello, yesterday I downgraded to rooteable 4.2.2 rom in order to backup TA partition. Once I had backup, I updated to 4.3 (290) and unlocked bootloader, then flashed recovery. With recovery was easy to flash superSu. Now I have "stock" rom with root and unlocked bootloader, but I realized that x-reality wasn't warking anymore (because of the DRM keys loss).
I tried to recover TA partition, but I caused a soft-brick, wich I only could solve flashing a 290 ftf through flashtool, but I lost root. My question is: It is possible to have root and DRM keys (TA partition restored)??
Thank you very much.

So, apart from losing x-reality and some Sony apps functionalities (which I dont care). Do you lose something else? I heard about losing bionz processor, but camera still works, then I dont know how far this is true.
The incompatibility problem of root and restored TA partition, is because flashing recovery (which modifies kernel) or supersu.apk it self?
Thank you VERY much!
You loose bionz, but not x-reality. I unlocked my bootloader and I have x-relity enabled.
Some ROMs won't have working camera, for example: android 4.4 KitKat ported from xperia z ultra GPe, and some other ROMs.

I can see that the x-reality option is still on menu, and you can enable/disable it, but it doesn't work. Before, I could see in the first second of picture showing how x-reality improves the image (its an effect that can be seen with the naked eye), this is not happening now. By the way, its for sure that bionz stop working? How could I take pictures without it?
Thank you

Not sure about bionz, but I guessed it as I had the x-relity option enabled. I can't tell if it works or not as I don't have camera (I'm using ported 4.4)
It would be nice of someone confirmed it.
Correct me if i am wrong.
Bionz is a service which improves the pictures after a shot, isn't it ?
Bionz and X-Reality are things u can't detect that easy like "oh that effect is from X-Reality" or something else.
I thought the main reason for not working cameras on other roms was that the dev's didn't apply those 4.3 changes :S

Bionz it's a image processor that includes xperia Z1, it process the pictures taken instead the cpu. I dont know if it's easy to detect if it's working or not. But in the case of x-reallity it's very simple, when you open a picture in Sony gallery app, you can see how the picture "improves" quality in the first second. It is no so evident in all pictures, but can be detected by a naked eye, as I do.
My only doubt is about bionz processor, I already know that I loss x-reality. But I want to be SURE if bionz processing is also lost. I want to have full root (with unlocked bootloader), and have bionz enabled. I dont care x-reality or Sony apps.
Thank you very much

Not true. If you have a TA backup, install .290, unlock bootloader, install a recovery, root, reflash stock boot partition, restore TA partition, you will end up with a booting, rooted, .290 installation.

4.2: Camera doesnot work (BIONZ is disabled)
4.3: X-Reality doesnot work, camera still work
4.4: X-Reality + Camera still work
BUT DRM KEYS ON TA PARTITION WILL LOSS FOREVER IF YOU DO NOT BACKUP BEFORE UNLOCK BOOTLOADER, AND ALSO YOUR WARRANTY.
i dont have the warranty anymore so 4.4.4 is the best to unlock cause x-reality and camera still works?

It is recommended not to do that first, but to root first
That way you can backup the TA partition to relock your bootloader and restore your DRM keys if you want to. If you unlock first then you lose the DRM keys forever.

Unfortunately, as of right now, there's no way to relock the bootloader, and your DRM keys are lost forever.
You can try the custom kernel in the ROMs.. section, which includes a DRM fix, which maybe can restore some of the functionality of the camera.

Ooo really =( so please could you suggest me
Which one should I try?
A lot sure has changed since my previous phone (Z5 compact). Back then, simply flashing stock firmware automatically relocks the bootloader.
I'm surprised that's no longer the case.
Guess we'll continue to see little to no development of this phone until major breakthroughs.

There is no way to re-lock your bootloader once you have deleted the TA partiton. There are so many warnings on your way to unlocking that tell you this repeatedly.
You can use sToRm//'s Sony Xperia XZ Premium TWRP + KERNEL + ROOT + DRM fix/restore
app to enable your DRM again, then you can take pictures and everything is as before.
