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.

nope, recoveries dont back up your drm keys.
you have to use the Backup TA tool that was posted, this one

Remember, ALWAYS, MD5 sum check before flashing, flashing someone else's or corrupted TA will HARD BRICK your device,

If we are talking about 4.3 version, then none.
But - maybe if someone could confirm that X-Reality will stay after unlocking and using stock/stock based ROM.

Hey, if you unlock and dont see any thing strange, be happy. Dont go search for missing things
Many users saying about issues when unlock BL even on 4.3. When we will unlock BL and do not missing anything?
I think we have to wait new year when custom roms will find the way.

Things like X-Reality aren't easily replicated, otherwise they won't need to wipe the related keys. However, at certain times, I found the over-sharpening of X-Reality bothersome, and I switched it off.
Anyway, I don't see any issues with keeping my bootloader unlocked. I really don't miss anything, and I doubt most people would notice something's missing till they're told about it.

Yep, I think is not a big deal X-Reality Engine so it's true when we Unlock Bootloader on 4.3 we lose BIONZ Processing and X-Reality Engine?
If yes, what consequences we can have on device?

I will unlock now, but I already updated to 4.3 and I can't root my phone with locked BL to backup TA. I don't care about warranty, I brought the phone with intention to come on XDA an flash, so I was aware about losing warranty.
Even if I backup TA I will lose BIONZ and X-Reality anyway so backup TA to me don't make sense.
I am just worry do not lost something what I will need further time and I referring about the functionality of the device.

Downgrade to 534 and backup TA, then upgrade again. Just backup TA in any way possible.
Restoring TA relocks the bootloader and restores X-Reality and the likes.

I don't know of any programs, I simply use dd to backup and restore, but I'm guessing any program that does that is simply a script that uses dd.
I never saw the advantages of X-Reality in photos, only saw it in videos, and I can't see it anymore.
Restoring the TA doesn't need flashtool, adb is just to make terminal access easier and transfer the backup, technically you could just use a terminal emulator on the Play Store and upload the backup to Google Drive without using a PC. You just need to be rooted.

Restoring TA that mean restoring the phone to factory state, that mean I can't do that if I am on Custom Rom with Custom Kernel.
Factory state I will need just for warranty or I have to choose what I want, Custom Rom with Custom Kernels without X-Reality and BIONZ or Custom Rom with Stock Kernel with X-Reality and BIONZ?
What you people will do?

What is this you go on about BIONZ?
What, your camera now takes raw photos or what?
How does your camera work if your image processor supposedly doesn't?
If you manage to flash your way to a custom kernel and rom, how hard is it to go back to stock and then shove your DRM keys back in there?

BIONZ processing and X-Reality maybe do not influence much the functionality. I am just careful do not lose some pieces which I will need in the future but the only thing what people are saying is that I need the DRM for restore to stock.
Like I said, why I should go back to stock? Just for warranty, who cares! In this DRM keys is something what I have to keep?

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.

hi guy,
is there a dev out who build a tool for backing up TA?
Without TA-backup it is no good idea to root your Z3C (loosing the DRM-keys).
Thx in advance
m.
Currently we cannot backup the TA partition because root is needed for that. Once we have a working root exploit that doesn't require an unlocked bootloader you will be able to backup the TA partition.
I don't recommend unlocking the bootloader due to the loss in camera quality. Even though there currently is a hack available which restores the functionality after a bootloader unlock, not everyone reports it as working properly.
Obviously if the camera quality and Sony services don't matter to you there is nothing stopping you from unlocking the bootloader

First, you should not use your email as a username.
Second, there is no known way of backing up DRM keys, but you can re-enable function of those using DRM restore (search the forum a bit). You can always relock the bootloader using Flashtool (again, search xda or Google) to regain warranty and also to get official updates. You can also flash any firmware using Flashtool without the need for official updates.
Oh and don't open three threads for three questions and especially not in general section but in Q&A...
