[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] Updating to 4.3

Hi guys,
I have just rooted my new Sony Xperia Z (Android 4.2.2) and I would like to upgrade to Android 4.3.
I was wondering if there was anyway to get the update without loosing my root access?
I am pretty unexperienced at all this stuff. I've heard that "flashing" the 4.3 firmware keeps the root access?
Thanks,
-Lambo

Just flash a prerooted 4.3 through cwm and your root is preserved, just like that

If your bootloader is locked just update it over the air. If your bootloader is unlocked flash a prerooted Rom via Cwm or twrp.
Just flashing a ftf file via flashtool wI'll make you lose root

[Q] How do i get from vanilla to Xposed?

Hi everyone,
So i have an xperia z1 on 14.3.A.0.757. Vanilla, not rooted, havnt unlocked bootloader.
I would love to get Xposed Framework but i have been searching all over the interwebs but its so unclear.
Could someone explain to me EXACTLY what needs to be done to get from vanilla to xposed? And how i would go about doing this, the easiest way! Any links to good explanations and step by step guides which are safe would be much appreciated!
Thanks,
Marcel

Root, then install it like a normal APK.
If you are unsure how to root, look in my signature

Is there any way to root the phone without it being wiped?

Not from a 757 firmware.
You can try excluding data when using flashtool, but I wouldn't do that.
However, if you can update to 4.4.4 via pccompanion you will not lose data and you can root that very easily without losing data using newroot

wait so i am on 4.4.4 and updated to it via pccompanion, does that mean there is alternative root method which means no loss of data? I heard bout some towelroot thing, does that exist for the Xperia Z1?

Yes there is, what build number are you on, you said 757, but that's not 4.4.4
Please post what it says in the build number and android version from settings/about phone

4.4.2 (woops thought i was on 4.4.4....)
14.3.A.0.757

OK, you will probably lose data when rooting then.
Flash a FTF from the FTF mega collection that ends in .108 or .118
then use the newroot tool to root it

Because you cannot root 757 FW
Either downgrade to android 4.2 (i.e a firmware ending in .534) or upgrade to the latest android version 4.4.4 (ending in .108 or .118) and root it.

removing the bloatware from the system is the reason why it doesn't work! The updater recognizes the missing files and aborts the update, so the only way to get the Ota update is to bring the removed apps and files back!

OTA will always fail when you're rooted, as signature checks will fail. You need to flash a pre-rooted 157 after wiping system and caches (not data).

Install a non-rooted, fresh copy of 157. Close Sony Updater tool(s).
Flash the 108 kernel using Flashtool. Close Flashtool.
Root using XperiaRoot. Close XperiaRoot.
Flash the 157 kernel using Flashtool. Close Flashtool.
Install XZDR Dual Recovery, and use TWRP from now on. CWM is old and should be killed with fire.
Send me $50 and a large pepperoni pizza.
