I wonder how i can remove root and custom recovery. Do i just flash a ftf with flashtool?
i flashed an orignal ftf firmware and it seems something is wrong. I cannot access recovery. Other than that lost root and the devices seems fine.
Any ideas on why i cannot access recovery?
Stock Ftf has removed recovery

Guys , some people are reporting that they are unable to revert to stock rom after flashing custom rom.
If you want to save your phone , then i highly recommend you to make a complete backup before flshing stock rom
go to cwm recovery and select backup/restore then backup (it will make your stock rom backup)
whenever you want to revert , go again to clockworkmod recovery and select restore under, backup/restore option
now last and most important thing to run stock rom ---> flash stock kernel using fastboot method
first grab stock kernel to do that , download your phones stock firmware from here = http://forum.xda-developers.com/showthread.php?p=10885406#post10885406
using 7zip extract kernel.sin file from .ftf firmware file
connect your phone in fastboot mode and run this command
fastboot flash boot kernel.sin
I'm doing it again and again without any problem.. just be sure to flash stock kernel before flashing stock rom.
thanks, i will try this method too
first flash stock kernel , then using flashtool flash firmware , am i right ?
Stock kernel (kernel.sin) is included in the package (of official stock firmware). So everytime you flash an official stock firmware, kernel.sin is also flashed. No need to flash kernel.sin before flashing stock firmware. Correct me if im wrong.
I also think same , i tried that method by noooooob and it worked too

yes you have to unlock boot-loaders first
i recommend to unlock by this method = http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
if you want to install clockwork mod recovery then follow this = http://forum.xda-developers.com/showthread.php?t=1384200
Install CWM without unlocking bootloader
You don't need to unlock the boot loader to install CWM.
Follow instructions here to root First

This is how I did it on my Ray
I always considered flashing with Wotanserver to be the best way to go back to stock. It basically takes care of everything. Sure, you'll have to root again afterwards, but that's not exactly very hard.
wotan server is also a good choice

download firmware which you have before installing custom rom, then flash it using flashtool.
Hi!
Somebody in a different forum suggested that it might be possible to root the latest firmware (23.0.1.A.0.167) by downgrading the kernel (http://forum.xda-developers.com/showpost.php?p=56590546&postcount=1224).
Can anybody confirm this method to work?
I purchased my Z2 tablet yesterday and was foolish enough to believe that I can upgrade to the latest firmware and still root my device (with a locked bootloader).

It doesn't work. You end up to bootloop. However you can flash prerooted firmware in custom recovery and have fully rooted device.

In order to do so I have to unlock my bootloader and with that I'm going to lose my drm keys, right?

No. If you easy root and install the dual recovery beforehand you flash from that.
But easy root doesn't seem to work with the latest firmware, they closed the vulnerability that easy root is using

Easy Root Tool works just fine with .314 firmware. So if you are now on latest .167 firmware, downgrade to .314, root it, install custom recovery and flash prerooted flashable.zip in custom recovery. Done.

Ah, I didn't know it's possible to downgrade the firmware
So I need the firmware flash tool and a ftf file of the 167 firmware, right?
And it can be done without root and a locked bootloader?
Sorry for all the newbie questions, I'm coming from HTC devices and it's a little different there

You need:
- latest Flashtool with drivers installed correctly for your device
- some working custom recovery
- Easy root tool
- ftf file you need is 314 firmware of you device where you have to downgrade to easily root it
- prerooted zip file included you device 167 firmware, SuperSu install files and latest dualrecovery install files.
You don´t need unlocked bootloader for this. Point of downgrading is to achieve root easily that you can have root with 167 firmware? Or do you mean that can you achieve root on 314 firmware without having it before? If so, yes you can with Easy root tool.

thanks for your efforts!
in the meantime I managed to downgrade the firmware to 314, successfully root and backup TA
I installed superSU from the play store and it is telling me that I need to update the binaries and I can choose between "normal" (which doesn't work) or through "twrp/cwm"
I didn't install any custom recovery yet, so I'm not sure how to move on from now
should I install dual recovery (from here: http://forum.xda-developers.com/showthread.php?t=2785598), after flash the latest supersu from recovery and finally flash prerooted zip file?
do I need custom recovery to flash the prerooted 167 firmware?
or should I just run the OTA to get 167 firmware (will the device still be rooted after the update)?
please advice

Good to here you achievment. If you can´t update SuperSu binaries by "normal" way easiest might be to flash SuperSu latest update from custom recovery. I recommend dual recovery from your link and when installed use TWRP.
So install dualrecovery, flash latest SuperSu and then prerooted zip. If you end up without write permissions to system here might be solution for that.

Bootloader is locked... was on stock KK rom and was rooted (towel)..
Installed dual recovery and facotry reset in recovery, flashed C6833_14.5.A.0.270_Customized HK flashable prerooted recovery then the recovery flashable. Rebooted and now it is stuck at the Sony logo...
Did I kill this thing?
EDIT: Was able to flash original firmware with XperiFirm. How can I update this pile to Lollipop? The PC companion app wouldn't work when the phone was bone stock.

Brother download the 5.0 firmware. 270 through xperifirm and flash using flashtool. Then root using kingroot apk and then flash xzdual dual recovery using the bat script and then u can change the kingroot apk by installing super su zip and then removing king root and King user
So, I think I finally did it. I broke my phone.
I wanted to flash the new Existenz Rom 6.0 and the flashing worked fine. The phone started and it got stuck in the Xperia logo. I than downloaded the Bootloop Fix. To make sure nothing goes wrong I wanted to do another factory reset. Somehow, my phone uses two roms (Philz custom recovery or something like that (I flashed the rom with this) and a TWRP Recovery). My phone booted into the TWRP (which it usually doesn't do) Recovery and I thought "Well, I can do a factory reset here". So I did the advanced reset but after restarting I can't access anything! When I turn it on, there is still the Sony Logo but if I press up and down I can't access none of the custom recoverys. I'm truly desperate and I can't afford a new phone. Can someone help me how to fix this?
@DerDokktor
XZDR and similar recoveries for locked bootloader reside in /system partition , when you wiped your system you also wiped the recovery...
You'll need to flash an .ftf firmware with flashtool to recover your phone. If you want root and a locked bootloader flash a KK or LP ftf (as MM is not rootable yet), then root it with kingroot or something else you like, install XZDR from your computer and then you can go to the recovery again and flash existenz rom or any prerooted rom you want.
You could also flash a MM .ftf directly but then you won't be able to root it without unlocking your BL.
If you need help with flashtool follow this guide:
http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/
Edit: the first steps of this guide are to create your own .ftf , if you already have an .ftf downloaded you can go straight to the "Now that the FTF firmware file has been created, you need to flash your Sony Xperia device." section of the guide.
Hello,
talking here just about ROOTING not flashing CUSTOM rom!
I have one simple question. Is it possible to root device without unlocking bootloader? I have mediatek CPU MTK6750T and stock ROM flashable via SP flash tool. What if I just add superSu manually to the stock image and flash ot via SP flash tool just over /system partition?
Or what If I just flashed recovery (TWRP, CWM) over recovery partition? Could I root from there as well?
In both methods I would NOT unlock bootloader right? So I could be rooted without unlocking bootloader?
Please explain me if something will not work.
Or can flashing original stock rom Lock bootloader again so nobody knows?
Thank you: )

Bootloader restricts rooting or flashing recovery, system or anything else.
Therefore, you can't do anything without unlocking bootloader.

But SP flash tool can flash directly to partition right? so what if i use stock rom and just change recovery image file to flash? So it will flash stock ROM with my Recovery img. I will turn of checksum of course..
Or does bootloader really forbid this?

Oh sry, I overlooked the SP Flashtool part. You can flash without unlocking bootloader.

can you please tell me how would you exactly do that?
I'm trying to flash twrp by changing the recovery file in the stock rom but I can't seem to find the stock recovery inside the zip folder.
thanks in advance
