Hello guys.
I got my hands on my SONY XPERIA Z 2 weeks ago. Then I updated it to the Jelly Bean 4.2.2 immediately.
3 days ago, I got the 2.67 update. Next up, I decided to root my device. So I googled "XPERIA Z C6602 10.3.A.2.67 root".
I don't know what the number was, but the last 4 digits were 2.67, the latest update actually.
In time, I noticed that I had to unlock the boot loader first.
So I d/l'ed the Minimal Fastboot & Adb from the XDA and had gotten my Key through the SONY UNLOCK BOOTLOADER service.
I ran the minimal fastboot & adb then unlocked the phone. I ended up a data-wiped XZ after the operation as the 13-page application menu had gone and a 3-page one remained from stock XZ Jelly Bean firmware. That was normal actually, but the thing is that I ran the UBL operation on my smartphone solely to ensure that I have a BL unlocked smarty.
What I got after the second time unlocking was, um, SONY & XPERIA splash screen and then multiple reboots. Thus, I did some googling and noticed how to switch off the unit, using VOL+ & Power method. Now every time I boot it up, it keeps rebooting over & over.
As you all know, I cannot update/repair it through SUS or PC Companion as it's BL unlocked & EMMA is unavailable in my area.
I couldn't find a 4.2.2 C6602 Stock FTF but a 4.1.2 FTF to use with my XZ. I have to use Androxyde Flashtool.
Will this kind of downgrade kill my BLU'ed smartphone or can anyone help me out uploading the C6602 4.2.2 Global Generic FTF stock firmware or a link? Are there any other ways to relieve my phone?
Any kind of help would be greatly appreciated.
Additionaly, I've seen guys having the same problem because of other reasons, say, turning Airplane mode on.

I had the same problem,thought i had permanently bricked my Z!! I eventually updated flashtool to version 0.9.13.0,flashed stock .244 FW and then did a nandroid restore after rooting and installing cwm and VOILA!! Got my Z back to life! Hopefully that will help,bootloader is unlocked by the way!!!

i know it's too late, but you don't need to have an unlocked BL to get root. And i hope you did a TA-backup, so that your drm keys aren't lost forever.
Downgrading won't harm your device.
If you want to get the latest fw follow this :

Any chance you could make an FTF, im guessing yours is unbranded / SIM free?
I want to remove the o2 branding from mine.. .
Theres a guide on how to create FTF files, but it does mean you will have to restore your phone to stock...no worries if not, im sure a Generic Global FTF will appear shortly.

A quick note on root, it works fine, but, there are some residual issues:

Even if i mount /system as RW... a few seconds later, device reboots...?
I'm on O2 UK Branded firmware.
[Bin4ry]
Yes thats what it does. It has nothing to do with a faulty root, it is just a security option on the Xperia T which should prevent modifications to the System partition. When i have time i will take a look and tell which daemon on device it is so we can kill the daemon and modificate the system partition.
Regards
Ok, i rooted my Xperia T with the above method but when i change something in the System folder the phone Reboots and puts it back to how it was
any ideas??
Build 7.0.A.1.303
----EDIT----
Working perfectly now. I just installed V13.
Use V13, i restored my phone completely using PC companion, then re-rooted, i can mount /system as RW, replace files etc..all ok.
Worked for me.
I just bought an xperia T and it was sold to me as an unlocked phone. But, it has a locked bootloader( from vodafone uk). I am wondering if its possible to get it unlocked(paid or free) or atleast put a stock sony firmware even if it has locked bootloader? I am new to xperia and I dont know much about flashing..
Thanks.

Read the all in one thread in the Q&A section. All your answers are there.
Briefly.
You can easily get a free unlock and easily root if you dont want to unlock.
You can easily flash stock sony firmware without unlocking or rooting.
Basically read the all in one thread and ask any questions there

Xperia TL locked bootloader
Hi,
I rooted my Xperia TL with a locked bootloader, and I read somewhere that I can only install custom roms which are based on the stock rom. Is there anyway around this?
No
Sent from my star trek communicator
Sony Flagship device circa 2145
Didn't work on my T with .195, in either normal mode, or 'new' mode.
Also tried to downgrade to 303 but that didn't work either, Flashtool gives an error.
Anyone know if you can use the OTA upgrade to root, and then downgrade back to 195?
You are using the wrong version.
Upgrade to JB then use the latest version

Successful on my TL with JB 4.1.2 using the 3rd option.

Hi, I unlocked the bootloader on my xperia t lt30p one time with intention to root it and install custom roms but never did as I nearly bricked it when putting a kernel on. I managed to put what I think is a stock kernel and rom back on, but I went to update it the other day and pc companion says that it could not complete the operation because the phone has been modified. I read somewhere that having the bootloader unlocked can cause this, so I wish to re lock it. Could anyone point me in the direction of a good tutorial to do so? Cheers...

the link provided by our friend is quite good, that's where you have to head over
and about the tutorial, tha't so easy, just flash that FTF file via Flashtools
power off your phone, open flashtools, select flash logo, then FLASH MODE, then connect your phone as you are pressing down the VOLUME DOWN button, and let it do the rest
disconnect and enjoy your relocked bootloader
So I won't need to re flash the rom again? sorry. I'm a bit of a noob at phone modding. Pc's I can do. Not phones yet. Hahaha.
no, flash the relock ftf found in the dev section, and it just relocks your bootloader, your rom will stay the same

RElock won't affect you rom, BUT if you unlcok AGAIN, then at the very first start up of the phone when it is the first time after RE-UNlocking, it will have a factory reset
just wanted to let you know
but for now, NO, it won't touch your firmware
Just done it. Worked. Cheers guys,

Hello im new to all this software stuff and well i have a a sp on 4.3 but it crashes way too much and well i want to downgrade but my boot loader status says: Bootloader change allowed: no or sumthing like that but is there anyway i cud unlock my bootloader or downgrade plzz heellpp
:crying:
It's strange. No, seriously, it's actually strange.
My Z3+ was a non-unlockable device (see the first attachment, it's a screenshot I took the first time I booted the phone), I installed several OTAs (it came out of the box with Android 5.0) so it was actually locked.
Now, tired because I didn't received the 6.0.1 update on my phone (on both Xperia Companion, which replied always with a connection error, and OTA), I checked the bootloader status. Ta-da, unlocked. How could it be possible? I actually did nothing, also it was non-unlockable, so I can't really explain myself what happened.
And also...how can I now receive updates? I can't remain on 6.0 forever. Thanks. And sorry for my bad english.
Up! Anyone?

Uh, I tried to use Flashtool when I had a trouble with camera focus, but it failed and I had to repair it via Xperia Companion (and if it worked, so bootloader was still locked). Do you think is this?

Well I never used xperia companion, but flashtool always worked for me, I nearly flashed 7 times due to many issues like boot freeze, locked bl and in my final attempt both my bl was unlocked and the boot freeze problem was gone.
I flashed the last stock CE1 using Flashtool, now my bootloader is again locked and non unlockable. I'm not understanding...

1- In order to downgrade to Sony's stock rom you don't need to unlock your bootloader. All you need is a firmware of your choice, which comes in form of an ftf file, and flashtool. Plenty of guides on the Internet and xda about that.
2- If you insist on unlocking your bootloader and you are aware that it will permanently and irreversibly erases your phone's drm keys, you should disable myxperia and any other taking app you may have on your phone first. Then likely the status will change from no to yes.
