im kinda nervous rooting 4.3 cause im reading lots of people hard bricking their phone on 4.3. is it really safe to root 4.3? i will be followibg this tutorial:
forum.xda-developers.com/showthread.php?t=2572988
Hard bricking happen when you do something stupid. Also in general there is a Thread How NOT Brick your Phone. Anyway, to get root you have to downgrade again to .534, I recommend to root with Bin4ry, then update directly to .136 with instructions given by NUT Here. You cannot keep root updating system via OTA, you will lose everything.

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.

Are you joking? We already told you what you have to do but I think you didn't read a word from all the post because you will know something now.

Hey guys,
I just bought my Xperia Z1 model : c6903 4.3 Jelly bean version 1.4.2.A.1.136, I want to know this is work to root and how ? because I keep tried for many root program like vroot but it doesn't work even I do not know how to enter to recovery mode too. I tried to do as many way to enter to recovery mode what I have found but it doesn't work.
Thanks for your helping !
There's no way to root 4.3 directly yet. You have to downgrade to 4.2 root & install recoveries than update with custom rom.
The only way is a method to get full root on your phone. Downgrade to the firmware .534 provided by NUT to not lose IMEI, Root with Bin4ry, then follow the instruction to Update to .290 HERE, then follow the instruction to Update to .136 HERE.
i know what you're thinking.. if youre asking for help you probably shouldn't be playing around with this stuff.. well, it's just that i've only recently switch from iDevices, to the Xperia Z1, i've only ever had apple products until 5 months ago.
i've searched for hours yet can not find "simple" enough guides for "noobs". i'm not stupid, its just confusing being linked to site after site after site just to find step one.
i'm stock, 14.2.A.1.136, ive read i must root to do TA Backup, i've tried downgrading (to a rootable FW) using flashtool etc, but i just kept getting bootloop (unchecked all boxed and check the "dont verify"?). i cannot flash a rooted 1.136 because you must have unlocked bootloader, & if i do it without ta backup, ill lose my keys..
i guess what i'm asking is if someone can provide the correct way to downgrade to a rootable firmware. what steps do i take in doing it all correctly, as in, downgrading, rooting, flashing cwm, kernals, cyanogenmod etc.
Downgrade to 543 via flashtool, root your device and upgrade it with the method provided by nut

Use .534 FW provided by NUT from Post #3 HERE, then Root with Bin4ry and Install Dual Recovery, then Follow the instruction from HERE to Update directly to .136. When you got Rooted your Phone you can Backup TA First then Unlock Bootloader and then think to install CM. Watch Video Tutorial Hot to Root too.

thanks guys.
if i was wanting to just install cwm & cyanogenmod, is there any need to updated from the rooted .534 to 1.136? or can i just flash them both while on the rooted .534?
i've no access to a computer atm, but will downgrade when i can & click thanks.
EDIT; bootloader unloack bug exists with 4.2, which is why i have to update to 1.136, just remebered that. Aha
Hello All , Currently i have Xperia Z1 C6903 Running Android 4.3 "14.2.A.1.136" , and i got 4.4 OTA Update .
My question is if i accepted the update , can i root it afterwards by unlocking the bootloader and install custom recovery , and root it ?
or i can root my current os 4.3 then update to 4.4 OTA and the root will be still there ?
You can Root it by Unlocking Bootloader but if you do so you will lose DRM Keys forever and your Warranty will be void. No, you can not root any current Android 4.3 or 4.4 directly, to do so you have to follow the steps by NUT to downgrade, get Root then Backup TA (very Important) then you can update to 4.4 or 4.3 always with NUT method. Why not OTA? Because you will lose Root. So the only way is to Downgrade to get Root and Upgrade after.
Never accept an OTA with an unlocked boot
Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks
Figured out. Thanks
