Hello, sadly I have rooted the Z1 within .534 without unlocking the bootloader and didn't realize that update via PC Companion overwrite the root access. I updated to .257 with PC Companion and then I have a Z1 updated, unrooted and without being able to be downgraded to .534 as I have read in other threads.
Can anyone help me to root the device in this condition? Suggestions?
Thanks

Download a .534 firmware FTF here : http://forum.xda-developers.com/showthread.php?t=2469191
Flash it with Flashtool : http://www.flashtool.net/index.php
Root with Kingo Root
Update to .257 with OTA
You follow the either one of the 3 or 4 guides that are in the general section.
PS, you can always downgrade no matter of whether you are rooted or not.

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.

Android 4.3 FTF .290 Root only for Locked Bootlader, Here
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...

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

Hi,
I was on .234 rooted and decided to build my own FTF using the .270 update I downloaded from PC Companion with the PRFCreator tool. I added the .zips for Recovery and SuperSU and flashed the resulting FTF with Flashtool but my phone does not have root and SuperSU wasn't installed. I tried to run the root command in Flashtool but it failed.
Can anyone tell me what the best, most recent method for rooting is as the chinese tools in the sticky seem a bit outdated. What are the main barriers to root and how can I do it without having to loose all my data?

How are you able to download the FTF file directly from the Sony PC Companion app without it being flashed straight to your phone?
The best method still for Z1 is too downgrade to 4.4 and root it then pre-root upgrade, there is the Chinese root but not sure if that works properly on Z1 yet.
Just root using KingRoot app it's just one click and you're rooted I tried it on my C6903 (.242)
I was a pro Symbian firmware modder in good old Symbian days. And now migrated to android.
Thus this will be my first Android root and if succeeded I'll make and release some good CFWs.
I want to root my Z3 Compact coz some apps needs device rooted and also I dont want any restrictions.
My Z3 Compact is under warranty and I dont want to brick it nor wanna void its warranty.
I just want to Root my Z3 Compact to stock original firmware.
Currently I'm on KITKAT 4.4.4. ver. 23.0.1.A.5.77. INDIA (D5833)
Not interested for Lollypop. So please dont suggest to.
I know I have to follow the following thread:
How-to: root, keep and backup DRM keys, etc. [KitKat/Lollipops]
Still some queries before proceeding further:
In the above thread it states that,
---Downgrade the firmware, as the root exploit only works with older firmware such as 23.0.A.2.93.
So does that mean I have to downgrade below my current23.0.1.A.5.77. ?
---Downgrade fw to 23.0.A.2.93 (Device D5803) or anything prior to 23.0.1.A.5.77 (december fw)
So does this method also work on D5833) ?
---Upgrade the firmware to the latest version, while retaining root access.
So do I compulsorily have to update to any latest ver. of Kitkat or Lollipop?
I dont wanna move from my current 23.0.1.A.5.77.
---Also what is pre-rooted image and non-pre-rooted image? Which one to go for?
---Also I dont want to Unlock my Bootloader so is Rooting possible without unlocking bootloader?
---Finally I need Stock Original Sony INDIA ver 23.0.1.A.5.77 (D5833)
So where can I find it?
Answer my queries as they appear to get a clear idea.

Cannot answer everything but will try : it should work on d5833. All you need is the old firmware for the root exploid. Pre rooted image is a zip file which u can flash via recovery after u root ur current firmware and install recovery. With this u will have root from the beginning. Nearly all flashable rom have root access.
Dont know if india has some difference in firmware but u could try a pre rooted international firmware.
Unlocking bootloader is not needed for root as long as u stay on stock roms. If u want try cm12 or something else u have to unlock.
Reason for needed downgrade is the fact to backup drm keys(ta partition). Root would be easy just unlock bootloader install recovery flash su, done. But then drm keys are gone. That is the Reason for this procedure. If a general firmware wont work for u u have to download the indian firmware via xperiafirm and use prfcreator to build ur own pre rooted zip

- Root with locked bootloader: Yep!
- Sony's stock firmwares: XperiFirm (KK or LP)
- Flashing stock firmwares: Flashtool
- Root: Downgrade to 23.0.A.2.106 fw (or older) and giefroot it (23.0.1.A.5.77 is not rootable by giefroot's exploit)!
- Utils for post root: XZDualRecovery and PRFCreator
- Pre-rooted image: Stock fw with root and/or recovery(ies)
- Non-pre-rooted image: Stock fw
Ok so once rooted can I again flash to 23.0.1.A.5.77 ???

Yep, do it this way:
- Install Dual Recovery (installer)
- Create a 23.0.1.A.5.77 pre rooted firmware with Super SU and Dual Recovery
- Flash it on recovery
Guys I found another guide which allows to Root on 23.0.1.A.5.77 . http://www.ibtimes.co.uk/how-root-xperia-z3-z3-compact-locked-bootloaders-1485046
What you suggest??
I'm not able to find anyware Indian ver. of Xperia Z3 compact D5833 KITKAT ver 23.0.A.2.93.
If anybody willing to help me get it somewhere only then I'm willing to root with the method mentioned here.
Also whats the diff. between Commercial/journalist firmware and regional ones?
simplest way to root ANY smartphone without pc
1. Allow unknown sources
2. Install aptoi
3. Search in aptoide "safe remove system app"
4. Install it and run
5. It requires root and give you "root tools"
6. Install kingroot from root tools and run
7. Now you have root
P.S. In some models, from 4.3+, TB or busybox won't work. But you can use root rights for any application and uninstall unwanted pre-installed apps.
Have fun!
Ok so I decided to downgrade to good old Kitkat 4.4.4
I have the ftf file.
I dont want to root to anything but simply plain downgrade to kitkat.
Can I simply use Flashtools for downgrading?? Will my drm keys and bootloader will stay intact or will it harm??

Drm stay intact. Simple flash kitkat and u are good to go. Backup internal sd. Will be wiped
IS this method still the best for root?? Or is there any newer easy method to root without loosing drm keys and boorloader???
I want to Stock root my xperia zc d5833.
I'm on latest lollipop. Do I need to downgrade to Kitkat 4.4.4 for the root or can I root directly on existing lollipop?
What if i downgrade then how to upgrade to lollipop without loosing root???
I followed this guide and successfully rooted my z3c.
Have some very important queries:
Will a factory reset wipe the root access?
In point no. 43 you said--Open Flashtool and select the non-pre-rooted fw (this is 23.1.A.0.690), but DESELECT system: in "EXCLUDE" make sure you check the checkbox next to "SYSTEM", flash it.
So here can I flash the latest lollipop 23.4.a.0.546 fw in place of 23.1.A.0.690 ??
Can I now directly update to any latest lollipop/marshmallow via OTA/pc suite without loosing Root access?
