Dear all,
I have one more noob question again.
I was use a tool name Backup-TA-9.8 to backup my Xperia Z1 DRM. If I unlock it boot loader I know that the camera will not work. But if I relock it bootloader and restore my DRM. Dose the camera will work well again?
Best regards,

yes, as long as you have backed up the TA BEFORE you unlock the bootloader

But when relocking/restoring you will not be able to use those custom roms anymore (those not based on stock), just so you remember/know.

Small question, wouldn't it be possible to unlock, root (by pushing su binaries in a custom recovery and restoring stock recovery), and relock? No reason it wouldn't work imo, and I find this procedure faster than doing the downgrade, root, recovery, upgrade method

yes, but when you unlock you void your warranty, so unless you are planning on keeping an unlocked bootloader I reckon the extra minute it takes to downgrade etc... is worth it to keep your warranty
Also,
There is no such thing as a "stock recovery" on Xperia devices.
Also,
there is no need to install a recovery on the downgrade method if you do not want to.

No warranty here anyway.
I remember OTA-upgrading an Xperia Z, and that simply flashed a zip package in recovery. Why would there be no stock recovery?
And you need to install a custom recovery to do the upgrade, either that or copy files while the system is running, and I'm not sure how the latter would work without the system crashing at some point.

No.
Xperia devices have never come with a stock recovery accessible for the user.
Upgrading OTA means you do not flash it in recovery, you download the files Over The Air and then the phone upgrades itself.
No official upgrades are done in recovery, only custom kernels, custom roms or custom updates are flashed in custom recoveries

I know what OTA means, on previous devices with stock recovery, it simply drops you into recovery and does the flashing itself without the user ever having to touch anything. Same goes for wiping user data, it's done in recovery.
Whether the recovery is accessible to the user or not is another thing, and I didn't know about it, so thanks for that.

How do you do a TA backup on the Z1? When you do the TA backup before doing anything else you usually do not have root yet, so I wonder how to backup the TA......
Follow any if the several guides in the dev section on how to backup TA. I can see at least 2 guides on the first page

Hello everyone,
I just bought Xperia Z1 and I'm running 4.3 and would like to unlock my bootloader. Since I never did it before I still need to backup my TA first. Since this needs root I'm stuck in a loop: Backup TA needs root to work but root on 4.3 needs an unlocked bootloader to install cwm to install SuperSU...so anyone can help me how to do this?
To root the last 4.3 you don't have to necessarily Unlock Bootlader, just follow the instructions on this page, post #16
http://forum.xda-developers.com/showthread.php?t=2588331&page=2
After do that you can Backup TA and Unlock Bootlader but you have to UB only if you want flash Custom Roms with Custom kernels. To flash Custom Roms with Stock kernels or root your phone it's not necessary to unlock it.

1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...
So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.
Follow the advice I gave above

but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

ok... can we get the recovery by unlocking the bootloader by official way??
and i saw a doomkernel... by installing it in fastboot can i get the recovery mode with locked bootloader or i should seperately install the recovery..??
Please follow my advice from post #2

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.

Hi guys. I have recently signed up here and am currently a XDA and Android noob. But i do have some experience of rooting. (I often watch one of my relative root and do stuff with odin but only for Samsung). I currently own a SONY Xperia ZR C5502. It has android 4.4.4 KitKat.
And i have no idea how to root it or load it's boot screen. I'm trying to install CyanogenMod or an android lollipop ROM to it.
If anyone is kind enough to give me some advice or help I'd really appreciate it.
Thanks
Ahmed
Hi Hardwelling, Welcome to ZR Forums
i was a samsung user one day so i know what you feel now
For Sony Devices, to flash ".ftf" ROMs, flash kernels..etc , you should use Flashtool
It's the same as ODIN.
First
For Rooting your device you've several ways :
1. Root the device without unlocking bootloader (you'll not be able to flash any other ROM not based on Sony Stock one)
2. Root the device with unlocking the bootlader. (you'll lose your DRM Keys , however there are ways to Back them up, search xda for further information about DRM keys)
for both of them, you may search in the forums and you'll get a lot of methods (towelroot, Pre-rooted ROMS..etc)
Second
Installing Custom Recovery.. you may find plenty of them here, but i suggest the best one NUT's Dual Recovery,it works for both Locked Bootloaders and Unlocked Bootloaders.. Here you'll find all recoveries for Xperia Devices, make sure to choose the one beginning with "ZR", and go the "Installer" way, much faster
Third
Flashing custom ROM, it depends on what you have [LB] or [UB]..
Locked Bootloader Devices can't run CyanogenMod or AOSP ROMs..etc, as it only allow Sony signed kernels.
Unlocked Bootloader Devices allow you to run any kind of ROMS even Stock ones, but you'll lose some features of the Stock one as you lose your DRM keys
For myself.. i'm running Rooted LB Stock 4.4.4, and previously i was using this ROM
Use Flashtool to unlock the bootloader using SONY's official way..go to sony website and follow the steps there
Install the NUT's dual recovery using the installer..
Flash the pre rooted AOSP build :thumbup:

I would not recommend this approach as you will lose your drm keys.
Just follow one off many rooting guides wich you find on this forum.
After that take a backup of your TA partition with TA-Backup tool wich also can be found in this forum.
After this you can safely unlock the bootloader.
