Do not extract/rename or otherwise mess with the kernel ftf files that you downloaded. They are not zip archives. Place them as they were downloaded in the firmware directory then flash them in flashmode.

There's a tutorial on how to use flashtool in the general section if you don't know how to use it.

No,that's not the latest firmware. You're on the 423 firmware. The latest one is the 244 firmware.

Hi after successfully rooting with your method I have no signal from my carrier in fact it says emergency calls only. Hope someone can help cheers
[Xperia Z Android Development] johan8:
After root success, you MUST flash 244 kernel !

Don't use the old kernel.

Kernel for ZR

where i can find kernels for ZR. if i've firmware ftf if i select only kernel will it work?? :confused::confused:

[Xperia Z Android Development] imran_jasper:
Hi yeah I did flash the 244 but after it flashes I still don't get any signal

Any other ideas? Also just to point out that when I do flash the 244 it is very quick and I am not prompted to do anything other then unplug

Really frustrating.
[Xperia Z Android Development] Jonathan2677:
What apn are u using and did u select carrier in setup, I've seen no one have this problem so I'm sure it's just something missed also check your sim in a different phone I realize it worked before u flashed but maybe something happened to it
[Xperia Z Android Development] ujwals:
[MENTION=2784807]DooMLoRD[/MENTION] i don't think it will work on ZR.. we don't have have a rootable 4.2 kernel.. :confused:

So I checked it with another sim and am having the same trouble. I have also noted that otg doesn't work and u can't install apps from my external sd.

Do you think it's repairable?
[Xperia Z Android Development] kingvortex:
Something obviously went wrong. My advice would be to flash a stock FTF and start again from scratch. Download all the files from the OP again and check the MD5 sums of all of them before proceeding.

If you continue to have issues after that, then perhaps you should open a thread in the q&a section as this thread shouldn't get too full of posts asking for help. ;)
[Xperia Z Android Development] Don MC:
The problem imran_jasper is experiencing isn't an isolated case. I'm also having problems with phone signal. The signal drops for long periods of time and then returns again. The phone says time without signal is 42%. This has been going on ever since I rooted the phone (more than two days now).

I just flashed the baseband from 10.3.A.0.423, but it still says the same baseband in About phone (9x15A-ACEFWMAZQ-30110057-39). Maybe the baseband hasn't changed in .244.

I'll keep an eye on the signal, though.
[Xperia Z Android Development] indycar:
havent rooted yet and after reading this i went to check

14hrs on time 52% without signal
[Xperia Z Android Development] Don MC:
OK. So it isn't because of the root then. We'll have to address the matter in the firmware thread.

I'm not sure if it's the same problem because I didn't check signals, but my problem was that I couldn't turn on Wifi. Problem fixed by flashing 244 kernel from where I started.
[Xperia Z Android Development] imran_jasper:
I just want to get things back to normal. Not even bothered if I'm rooted now lol
[Xperia Z Android Development] kingvortex:
Then flash a stock FTF like I said.

If that doesn't work, then repair your phone with the PC Companion or Sony Update tool.

[Xperia Z Android Development] nastyfingers:
Hi, I'm having issues with the script part, it just hangs at creating temp folder.

It did the same when rooting other firmwares and I just did a ctrl+c to interrupt the script, then allowed it to continue. I assumed it to be a quirk in the system as I was using a virtual machine, but now it is just giving me the error "protocol fault (no status)" after cleaning and the "error: device not found" for each other line.

I have tried the script in os x but it just skips through to the end as soon as I connect my phone, giving the error "No such file or directory" for each line.

I have never used flashtool before but the old kernel seems to flash ok, I don't get any error messages or anything untoward sounding.

I have tried re-flashing the 10.3.1.A.0.244 firmware and starting again but the same happens.

If anyone can help it would be greatly appreciated.

I answered no and my root works just fine.

What is that about?

[Xperia Z Android Development] DooMLoRD:
ya i noticed that too

[MENTION=4904057][NUT][/MENTION] any idea on whats going on//?
[Xperia Z Android Development] kingvortex:
Since version 2.4.2.0, TWRP has included a root checker. If it detects that your device is not rooted, it will offer to flash SuperSu.

Perhaps the issue is something to do with that. Maybe the method it uses for detection doesn't work properly on our device.

I could be wrong. Just throwing an idea into play. :)

Will do mate. Thanks. It's all one big leaning process.

I had actually updated to the latest .244 build.. Is it ok to reflash .423 again to use this root method? I mean there wont be any conflict or brick rite? Asking bcoz u said sony has patched this.
[Xperia Z Android Development] Panaroma:
Thanks a lot! Worked after a few tries :)

But I have some issues.

First: lockscreen seems unresponsive sometimes

Second: over night in deep sleep it looks like the screen turn on off auto. :confused:
[Xperia Z Android Development] johan8:
Well, I think you are not fully understand what to do.

If you phone has upgraded to 244, you should downgrade the kernel to 423 in order to use this root method.

Again, KERNEL only ! Not the whole firmware.

About your concern, Doomlord has tested so that he released this root method.

Sony has patched the previous exploit so previous root method won't work, that's it.

After rooted, you should flash 244 kernel back to your phone, otherwise your phone won't work properly.

doomlord has post every steps.

Did you flash 244 kernel back ?

Did you reboot your phone to check it startup properly ?
[Xperia Z Android Development] nastyfingers:
Right sorted it.

I hope this will help anyone else having issues with vm's!

I ended up trying mac flashtool and script on a different physical machine, no joy. script part still acting up in terminal.

I re-flashed the .244 firmware, and created a totally new virtual machine, and installed everything required from scratch.

Everything was ok to step 6 where script was hanging at "creating temp directory" again. I tried this a few times and it still just hung at this step.

I restarted the vm and the phone, on next script run it went through ok and started pushing files, but then hung just before running the exploit. A few attempts at running the script again and it was still hanging just before running the exploit.

I restarted everything again and it skipped straight through to restarting the phone. The phone did not restart so i did it manually, then super su was there and root was working!

The just flashed the proper kernel back and all is great.

Hi to all,

I need help, previously I owned samsung, I never worked with Flashtool, now I have Xperia Z with the latest kernel. I want to root my phone, but I don't know how. I downloaded flashtool flashtool-0.9.10.1-windows and on initial screen I have this:

06/050/2013 09:50:53 - INFO - <- This level is successfully initialized

06/050/2013 09:50:53 - INFO - Flashtool Version 0.9.10.1 built on 2013-01-09 19:49:47

06/051/2013 09:51:02 - INFO - For 2011 devices line, be sure you are not in MTP mode

Than, I clicked on Flash Icon, chose Flash Mode, XperiaZ_C660X_KernelOnly_10.3.A.0.423_Generic_NL.ftf, without anything checked, clicked on Ok, and I have some screen that it says to reboot device and press back button.....but the problem is that on Xperia Z I don't have back button...

I restarted my phone, and after reboot I checked in About Phone...and see that I still have the latest kernel....where I go wrong?

How to flash stock roms with Flashtool

Basically, when it says hold the back button, you have to hold volume down instead and connect the USB cable.

Also, it might not make any difference, but you are not using the latest Flashtool. The latest is 0.9.11.0. :)
[Xperia Z Android Development] biker972:
Thanx, I will try with the latest flashtool, and with volume down :)

EDIT: I tried, and definitely I do something wrong.....I done everything from previous post, I don't know how to get this:

It should start flashing and once done will say "Complete"....Should I need to turn of Flashtool when press ok, before I turn off my phone...when I need to press volume down, and when I used Flashtool, phone is connected via usb cable...when is the moment when I need to plug out usb cable?

And also, I don't have option to enable this: ENABLE USB DEBUGGING....

OMG, it is so complicated :(
[Xperia Z Android Development] nastyfingers:

In future you can also turn off your phone let it sit there,open flashtool, select flash,pick ftf and check anything you want,then hit flash it will prep the files and tell u when ready to plug in your phone in flash made,now hold volume down while you plug in the cable when light flashes let go of volume and it will start

I tried that already as I mentioned in my post earlier. Flashtool gets stuck at the "Processing Loader" point..... it doesn't go beyond that ........ that's the problem I'm having....... it normally doesn't happen.... waited quite a long time, but it does not go beyond that point....

FYI to use flashtool

1) open the flash tool program and press flash.

2) wait for instruction to ask to go to flash mode

3) unplug the cable from your phone

4) off your phone.

5) press and hold the volume down button while plugging the cable into your phone.

6) you should hear some USB connecting sound from your com speaker.

I did not "disable" or "unroot" anything.

As I wrote before and pointed at the specific posts, the mileage can vary, someone does not have survival mode at all and retained the root, another one has lost it completely, etc.

So, it's only YOU who knows what have you done, delete, modify with your stock rom and why OTA does not work for you

Did you mean that you updated your phone through PCC and you keep your root???

Beacause my OTA also failed,maybe because i delete some system apps before(via TitBCKUP).

Did you use something like OTA keeper or SU Survival mode before updating??

What about recovery mode,i have Dual Recovery installed will i keep that also or no?

[Xperia Z Android Development] Tungstwenty:
Applying a new ROM through pc most of the times will remove root, as the /system partition is formatted and replaced with a brand new image, as opposed to having its *contents* selectively removed and replaced (OTA), which some root keeping techniques might resist against.

After upgrading to 244, just use the method on the OP to regain root.
[Xperia Z Android Development] kingvortex:
That's because /system is wiped when updating via PCC or SUS.
