Unlocked or locked bootloader?
If you are unlocked, here's the easiest way.
1. Download Advance Stock Kernel with Recovery v05 (FW: 10.1.1.A.1.253) (NEW) from http://forum.xda-developers.com/showthread.php?t=2167381
2. Download SuperSU-1.25-Busybox-1.20.2-UPDATE.zip from http://forum.xda-developers.com/showpost.php?p=38154110&postcount=2
3. Copy SuperSU-1.25-Busybox-1.20.2-UPDATE.zip to your SD card.
4. unzip Advance Stock Kernel with Recovery v05 (FW: 10.1.1.A.1.253) (NEW), and extract boot.img.
5. use fastboot to push boot.img (Which contains CWM).
6. Reboot into recovery, and flash SuperSU-1.25-Busybox-1.20.2-UPDATE.zip from SD card.
You've got root.

*Follow the steps exactly and you will get back root with recovery. Not sure whether you have recovery in the first place as you didn't state.

No have any recoveries, just simple phone with the new firm
Xperia Z

Guess you need to downgrade first and ensure you have root, recovery before moving to the instructions which I have passed you earlier on.

Flash with .434 ftf, root and install dual recovery for locked bootloader. Goto CWRP recovery (volume down) and wipe only system install either of the available already rooted zip. dont wipe cache/dalvik cache. reboot. install supersu from play store and uninstall previously installed superuser app. thats it!

Root from stock Rom will be here soon just wait. If someone wants to root they have to downgrade and update again using a different Rom if u do that won't the phone be unbranded then meaning future ota or pcc Won't work or am I being daft ,

If need be, keep a copy of the branded/carrier FTF on your computer that you can flash back to if you need anything to do with warranty, easy. For now, Global unbranded seems to be the way.

[Q][V][JB4.3] Keep root when flashing 9.2.A.1.199 with flashtool?

I can't find an aswer to my question anywhere, so I'm trying it here.
Phone: Xperia V
Does anyone know whether it's possible to keep root access when flashing the latest 9.2.A.1.199 firmware via flashtool over an older JB4.1.2 installation (rooted 9.1.A.1.140) when unchecking the "Wipe Data" and "Wipe Cache" options?
Or has anyone tried and succeeded? I'm reluctant to try myself as my system is running smoothly, but I'd like to update to 4.3 if possible. Only if I can keep root, though.
Thanks for your help!

That's good news! I assume that is how you managed to root your 4.3 on your TX?

I'm not really sure about that. Data partition won't be wiped but system will be together with su binary file from xbin folder.

Yes, that's why I was concerned. But Superuser also supports OTA survival, and it's installed in the user partition.

I kept my root not actually from 4.1.2 but after upgrading to 4.3.
Flash 9.2.a.0.295 using flashtool
Back up TA partition then unlock bootloader
Use the easy rooting guide:
Using flashtool, fastboot flash custom kernel.elf with recovery
Immediately reboot to recovery
In recovery, mount system then flash superuser update zip
Do not reboot but instead remove the battery
fastboot flash stock 4.3 kernel.sin
Reboot and restore your TA partition
Install scary alien root toolkit and save your root (read carefully the instructions)
Upgrade to 9.2.a.1.210 via OTA (not pc companion)
And that's it, you're in latest 4.3 and you're rooted!

Just one question, what to use to backup TA on .295 without root?
With the tool I found you can backup TA only if you have root.

Sorry, I forgot about that, if you're still in 4.1.2 you can easily root that, you can back your TA partition there and restore it later

Xperia Z1 Bricked

Hi guys I seriously need help. I bricked my Z1 c6903. I accidentally deleted the OS by wiping dalvik, system, etc,. Im sorry if this was already posted somewhere here. Im new to this. If someone would kindly help me or give me help in unbricking my device Id really appreciate it.
PS, Z1 was given to me already rooted. It has TWRP recovery, and I know that Im really stupid for tinkering with the advanced option. Im new to using custom recovery, rooting, etc.

If you still have recovery , boot into recovery, mount usb and copy ROM from your PC.
Flash ROM and restart...
If you don't have recovery, use flashtool to flash ftf. (534) root it and then upgrade to 761 (latest firmware)
BTW, your device isn't bricked, there's missing system, that's all...
And yeah...that wasn't stupid at all...this things happens and, if you ask me- TWRP team should change that wipe options...
It's not well made...
First option should be only cache wipe and advanced should have format data and system option...

I tried booting to recovery but it wont. Its stuck in the sony logo. I guess ill go with option 2(flashing ftf)
is it ok if I flash the ftf then NOT root it?

You are welcome mate
Yeap...
One thing is very important - use latest flashtool..and everything will be OK.
You'll be surprised how easy that is...
Flash firmware 534 (JB)
Turn device off, open flashtool and prepare 534 firmware, start flashing and connect device (holding vol down) connect device when flashtool ask for it, don't do that right away...
root it with binary method (just Google" binary root method xda") first link is what you need.
Install NUT recovery.
Restart to recovery, flash NUT 757, TURN DEVICE OFF!!!
And flash stripped ftf (that's kernel)
It's very important to turn device off, don't restart. (to flash stripped ftf)
I always practice to hit flashtool "start" button and wait for flashtool to ask for device, that's is the best way to be 100% sure your device won't leave flashmod

Man, I asked you do you still have recovery and you said no?!?
Use recovery to flash stock based ROMs like NUT or iHackers, flashtool or pc companion to flash stock unrooted firmware.
It won'tbe a problem if you have twrp (recovery), it'll wipe everything...

There is no stock recovery on xperia phones

Only time it has recovery when you do an system update, after system update is done it gets erased as it has no use

If the newroot tool deletes the cmw recovery then yes it will
But if you unroot you will not be able to access recovery even if the recovery is still on your system partition because you do not have root ....

Lollipop update on rooted stock.

Just received my xperia z3 compact and it was on old 4.4.4.
first thing I did was root it with giefroot.
I'd like now to update it to the latest stock lollipop while keeping root, and being able to install a recovery to flash xposed.
any idea what's the best way to do this?

Unfortunately I went ahead and decided to flash a 5.0.2 ftf with flashtool, it came back during the flash with a warning on system.sin
wouldn't boot anymore so now I'm waiting to do a restore via PC companion. (which will probably take me to 5.1.1)
I wonder why it failed.. second flash it fails withthe same warning on system.sin

You can just force reboot (Power + Volume Up) and then hold the volume down button to enter flash mode.
Download the 4.4.4 firmware ending in either 93 or 77 and then flash it using flashtools.
Then do the root + drm backup and then follow the instructions here.
