[Q] Best practice to backup TA on 4.3?

Hello everyone,
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
Now i see two scenarios to make it happen:
a) Flash 4.2.2 with flashtool -> root with flashtool -> backup TA -> upgrade to 4.3 -> unlock bootloader on 4.3 -> install root.
b) Wait for a way to root 4.3 phones without an unlocked bootloader.
Questions:
1. Would a) work and is it worth the effort?
2. Will b) be possible and if so, how long will it probably take until it's possible?
Thank you in advance for your replies, you guys are doing a great job here!

I am in the same your position.
What I do at the moment is wait for a root on 4.3 to backup my TA. So for the scenario A),1) depends how is it worth for you? If you really need the root because some indispensable app need root so this is the way. Root is important anyway because will give you full control on your device.
For the scenario B),2) if you are not obsessed on modding you phone you can wait but how long you ask? Sorry, no body know it yet, we all here waiting. They doing great job and for sure they come with a root for 4.3 without unlock bootloader but this will be next year.

Thanks for your quick reply, the only 'urgent' app I can think of now would be TitaniumBackup since I just bought this phone and would like to import my appdata from the old phone.
Just a noob question, in order to downgrade to 4.2.2 I just need to download the appropriate .ftf for flashtool and that's it right?

Yes, that sholud be fine. If you don't have data to save on Z1 check Wipe Data, Cache, Appslog, and uncheck "No Final Validation" in this way you will go back with a clean installation and ready to root, backup TA and DRM keys, Upgrade again, Unlock Bootloader and root your 4.3.
BTW if you have another phone you can wait to root Z1 anyway, when the root come to 4.3 you will transfer the application via Titanium Backup.

Just flash back 4.2 root backup, unlock and flash back 4.3, nothing bad can happen, don't be alarmed by losing imei when back on 4.2 it comes baxk once you flash 4.3.

Well, you DO loose your IMEI, but if you flash 257 then 534 you keep the IMEI and the service provider signal.

[Q] Downgrade from 4.3 (C6903) Xperia Z1 14.2.A.0.290 Generic NCB (Unbranded/Nordic)

Hi everybody!
This is my first post as I usual solve my problems just by reading others people posts.
I recently flashed my z1 (C6903) to 14.2.A.0.290 Generic NCB (Unbranded/Nordic) (4.3 android) as I didn 't like the DE(german version) with the bloatware. I rooted it before with kingo but lost my root after flashing the NCB version I'm now looking for a way to downgrade to a older ncb version root it with kingo and then do a ota upgrade to keep the root. Does anybody have the FTF therfore and what boxes should I pick I want to keep my data or should I let it do a full wipe do a backup with sony companion or the sony app on the phone and than play it in after finishing the downgrade root and OTA? Pls help me I' m completly lost and I'm really missing the root.
Thanks in advance to everyone!!!!!

My experience is that if older FTFs aren't in the mega thead (http://forum.xda-developers.com/showthread.php?t=2469191), then you won't find them anywhere. Mega thread only has a 290 FTF for NCB, so you may be SOL if you want to strictly downgrade to 534 NCB and then OTA to 290. However, as long as you flash a generic FTF, you won't get carrier bloatware.
If root is what you'd want, I'd go with [NUT]'s pre-rooted 290: http://forum.xda-developers.com/showthread.php?t=2572988. It's the easiest way to get full root.

..or you follow the instruction step by step here on page 2, post #16 http://forum.xda-developers.com/showthread.php?t=2588331&page=2

Here's a link to the correct FTF (note that it is .257, so follow the guides regarding rooting .257, or if you're savvy, install a .534 kernel, root with Kingo, install a .257 kernel again, then OTA)
https://mega.co.nz/#!WkolCYjB!IIXR5SgAn-J05MXmG26GYyi2P2sYcF34Avn73z5Y9n0
It is incorrectly named Generic SE, but it is the right customisation ID for Generic NCB (1276-9897).

Sony PC Companion can make a backup for you, I don't know how much will be saved as in order to flash a 4.2.2 ROM you'll need to wipe your data partition.

257 can't be rooted manually, only 534 can be rooted by vRoot/Kingo/etc.
Since you are downgrading, you must wipe data and will lose everything you don't copy off the phone.

No, it's not possible to upgrade 257/290 and keep root. You asked about downgrading, not rooting 290. If you have an unlocked BL, go read the dev thread on how to root 290. With a locked BL, you'll need to get rooted 534/257 and then flash a custom pre-rooted ROM from the dev forum.

Actually with OTA you keep semi-root, but in essence you're right. Actually I think the easiest solution is to flash a stock .534 ROM, root it with Kingo, grab TA partition backup, flash .290, unlock bootloader, flash a recovery, do a proper root, reflash stock boot partition, flash TA backup.

Yeah, true, I've just stopped telling people about partial root since full root is possible. Those who don't know to ask don't know what it means anyway, and it's just simpler for everyone involved to leave it out.

[Q] [Help] sony xperia z root

Hi everyone,
I have Sony Xperia Z C6603 with 10.4.1.B.0.101 firmware
I am new to this and I want to do:-
1.Root my device to backup the DRM keys using Backup TA
2.Then, unlock bootloader
3.Install CWM(maybe)
Any help will be appreciated.

You will have to downgrade to root and backup DRM keys.
More info and detailed instructions - How to root 4.3.
Sent from my C6603 using Tapatalk

Will I lose my data if I downgrade it?

You will probably have to wipe data when you downgrade, as sometimes the phone bootloops if data isn't wiped. You can try without wiping, but you may end up wiping.
Personal data and the internal SD card are wiped when unlocking the bootloader in any case.

I backed up all my data using PC companion, can I restore it back after rooted my phone and with locked bootloader?

I'm not sure, as I never used the backup feature of the PC Companion. I use Titanium Backup personally.

well actually you want to unlock bootloader for installing 4.4 ROM /Custom Kernels ?
If you only want to root,you will just need to download the Android 4.2.2 firmware 10.3.1.A.2.67 for C6603,then flash it using flashtool ( make sure you backed up all your apps using built-in Backup & restore app & save it in microSD card)
Next root it using DooMLoRD Easy Rooting Toolkit,that's all.
You can choose to install CWM / TWRP / XZDualRecovery
Then you can only download the pre-rooted Android 4.3 ROM
For me i'm using XZDualRecovery with eXistenZUltra ROM :laugh:
Hope you understand

Now I have rooted phone with the latest 4.3 and also XZDualRecovery.
I am happy with the stock rom and kernel now so I skipped unlocking bootloader. Or maybe I will consider eXistenZUltra rom, seems awesome.

Problem rooting Xperia Z1 (KitKat)

Okay .. So I'm running ver. 14.3.A.0.681 on my Z1 and I want to root it .. I heard of a method in which the phone must be downgraded, then rooted, then reupdated again using flashtool .. But every time I try to downgrade I get stuck in a boot loop .. I have managed to fix the boot loop problem by reflashing the 14.3.A.0.681.ftf
Please guys how can I downgrade without having this problem? And does this rooting method work? If not, what should I do?

Hi ralph97,
Here is what I did (although I was on .257 to start with)
1) Flashed C6903 14.1.G.1.534 Generic from here - http://forum.xda-developers.com/showthread.php?t=2469191
2) Install dualrecovery from here - http://forum.xda-developers.com/showthread.php?t=2261606
3) Flash SuperSU (via recovery) from here - http://download.chainfire.eu/282/SuperSU/
4) Update to NUTs .681 from here - http://forum.xda-developers.com/showthread.php?t=2687443
Each time I flashed an ftf, I cleared everything, so I made a backup (I just copied the stuff such as music, photos etc to my pc)
I hope that this helps.

If you open the BL there is no need to make all the way back to 534.
You just have to open the BL install a recovery, on the 680 ftf, and then install the supersu.

Yes this is true, but you may want to backup your TA partition before unlocking the bootloader and this needs root, so you have to downgrade to .534 anyway.
So, yes technically you can do this, but I DO NOT advise it.

Well, the first time you do it, probably it shoud be done as you say. :laugh:

i also do that...its work..dont need to downgrade..

You need root to do it, so it has to be done BEFORE you unlock.

Please remind to People the consequences in doing this! Like the Warranty, after Unlock Bootloader, will be Voided and even before that, like @gregbradley already said, Backup TA to not lose DRM Keys. The short way isn't the best all the time.

You do not reupdate by flashtool.
Only with the recovery.

You still need to flash SuperSU to get full root, but in step 4 just flash the ROM of your choice.

[Q] Rooting with C6906 with 4.4

Hello,
I have a Bell Canada Xperia Z1 C6906 (Locked Bootloader) on 14.3.A.0.757 that is unrooted and I would like some help/advice about rooting it with the least amount of distress since while I need the features provided by rooting I cannot afford to brick my phone. So any help would be very much appreciated.
I have looked through the information and I will provide what I know below - is it correct, is there more I need to do?
Install Flashtool and all drivers.
Backup my TA partition for future reference/restoration.
Download FTF firmware that is version .534 - I found C6906 14.1.G.1.534 Rogers CA (which should be compatible even though its Rogers and I have Bell?) and flash it via flashtool.
Root the Xperia Z1 with 360Root.
Download the NUT's latest locked dual recovery
Z1-lockeddualrecovery2.7.123-BETA.installer.zip (10.22MB) and follow the instructions from [DEVDB][TWRP][PhilZ Touch][CWM] XZDualRecovery 2.7.1XX RC
Download C6906_14.2.A.0.290.flashable.zip and C6906_14.2.A.0.290_Stripped.ftf, place *flashable.zip on the SDCard and *Stripped.ftf in the Flashtool/firmware folder.
Create a full backup of my phone through TWRP
Wipe Dalivik-Cache, System, Data, Cache.
Flash " C6906_14.2.A.0.290.flashable.zip", power off. In Flashtool flash everything (check mark System, data etc ?) for "C6906_14.2.A.0.290_Stripped.ftf". Reboot and on language select reboot into TWRP and restore DATA backup. Wipe Dalivik-Cache and reboot.
Update to the newest version of Android - download C6906_14.3.A.0.757.flashable.zip and C6906_14.3.A.0.757_Stripped.ftf from [STOCK][C69XX][4.4] Update to 14.3.A.0.757 [Root & XZDR][DE-/ODEX] by NUT. Place *flashable.zip on the SDCard and *Stripped.ftf in the Flashtool/firmware folder.
Repeat step 7-9.
Should have a rooted newest version of the Xperia Z1?
Did I miss anything or make it too complex? It seems like a lot of steps just to have a rooted and up to date phone.

Don't use 290 version, use 534.
There's a lot bricked device reported when guys flashed 290 over 757 and version before 757 (can't remember number of that version).
Also, if you don't plan to unlock bootloader there's no need to backup TA, it's OK to do that but it's not necessary.
You can't lose DRM keys as long as you don't unlock it.
And yeah...use binary root method (just Google "binary root method xda" and pick first result.
360 and Kingo are banned from XDA because they read and store your IMEI (and that's totally unnecessary)

So I should just stay with .534 and not upgrade at all? I was hoping for an up-to-date version since some of the features in 4.4 are really useful to me.

Hehe....no
Just use 534 to downgrade and root and install recovery.
Then flash NUT 757 prerooted ROM from recovery and flash stripped ftf (kernel) using flashtool.
Only thing what I wanna said is - flash 534 and root it don't use 290 - downgrading from 757 to 290 could brick your device...
Sent from my D6503 using Tapatalk

Ok!
So downgrade to .534, do binary root, install DualRecovery and then just flash .757.
Also I keep seeing you need to reflash DualRecovery, would I do so after flashing .757?

No need to apply a root process if you are installing dual recovery
