After searching around I couldn't find anything related so here's my problem.
After succesfully unlocking the bootloader of my Xperia Z it continues to work fine.
It prompted the initial startup screen (enter language, account info ect.)
I turned my device off and on... this is where the problem starts..
This is what i get
Sony brand logo>
Xperia brand logo>
5 repeated cloud animation of xperia logo and at the last one it stalls, Phone reboot and back to 0.
This goes on repeatedly until a hard poweroff or complete discharge ( I suppose)
So I know im kinda screwed, is relocking the bootloader any option? Contacting Sony atm for some sort of software replacement/flash anything..
Cheers, Geert
Try the safe mode,keep pressing vol down with power until the phone boot completely.
If the phone boot to safe mode than do a factory reset.

Welcome to XDA
you should go to the recovery thread in my signature. Read the first 2 posts.
Hope you recover your phone.
Hi everyone !
I have the same problem as GeertNool. My Xperia is stuck in the same loop. I have tried everything.
- Flashboot : stuck at 0% when i try to flash
- Pc Companion and SEUS = dead ends
- Safe mode : cant make it work
I read the recovery thread. It seems that the Kernel is malfunctioning but i dont understand what should be my next move. Am i supposed to let the phone reboot endlessly untill eventually the battery dies ?
Thanks a lot for your precious answers.

Yes.
When the battery dies the phone should reset itself.
After the loops end plug into a charger, not pc for now.
You should get a red led indicating low battery level charging is working.
After the red led you may get Sony boot screen or bootloops.
If you get Sony and then the charging battery icon, then charge to over 50%. Then use pc companion or flashtool to restore.
If you get bootloops then read my 2nd post from the recovery thread in my signature for bootloop tricks.
Please let me know if it works. I am looking to add the Xperia Z to my recovery guide.
If there are any questions about my guide please ask in that thread.
Thanks

takes a few atempts but it worked.
takes around 20 mins to download then install another 10.
i couldnt get flashtool to flash firmware as my phone is locked on 3 mobile firmware locked bootloader
i hope this helps you

P.S. don't waste time for Sony's Emma flash, they do not send login credentials in real time, site says they do manual user validation ...

I have the same issue here, the phone suddenly dead. Charge it using AC adaptor and wall socket and the red led flashs for about 2 hours, the orange LED never turns on. Try your advice and got this:
1) Vol up + Power not work (no vibration, nothing)
2) Flash with flashtool 0.9.10.2 beta6 with no lucky, indicated "device disconnected" after animation gone.
3) regress to flashtool 0.9.10.1, device connected and then stuck at "flashing data.....", the progress bar stay at 0% and then nothing.
P.S. bootloader is still locked but phone is ROOTED so I'm affraid it's out of warranty. Just got the phone as a birthday gift from my wife yesterday! She'd kill me if she knows that.
Update:
1) Power + Vol Up works now. The sequence does matter, I found I have to press the Power button first and then Vol Up, it dosen't work vise versa.
2) flashing still doesn't work for me. And I noticed that the LED turn green and then turn off immediately. I'm not sure if that is the cause. I'm sure when in fastboot mode (connect to USB port when pressing Vol Up), the LED turn blue and stay blue. Is my flash mode corrupted?? That's really bad!

Try sony update service or remove flashtool and install again and use another firmware(maybe the first one is corrupted).

Urgent. My Sony Z1 had rooted .681 version running fine for weeks. But trouble came today I tried to upgrade to .757. I had the flashable zip on the sd card, Booted into recovery mode then did a wipe and a factory reset. Then in the installation process of .757, the phone reboots to SONY screen and freezes. I could only use Vol Up + Power button to turn it off. It still freezes on the next reboot. It doesn't even vibrate at the start screen, so I cannot enter the XZDualRecovery mode. Please help.

You should follow the instructions in the thread.
You have to flash the srtipped FTF before rebooting. and there is no need for a full wip, you lose all your settings then.
To fix it, just flash a stock FTF and start again (You could try flashing the stripped FTF)
Hi, I sorry to bother anyone, but I need help because my phone is not responding and I don't know what to do.
C6603, rooted, dual recovery installed, bootloader unlocked (I think)
So here's what happened. I very successfully installed the existenz ultimate rom on my phone. It was a wonderful rom and everything was going well. However, I accidentally dropped my phone and needed to send it for repair. Before sending it to the shop, I decided to do a factory reset using the option in recovery mode.
When I got the phone back from the repair shop, I wanted to install the same rom. What I did was download the rom installer and then install the zip file using the recovery mode. I went through the AROMA installer and everything, So I thought everything was going fine. When the phone rebooted, it showed the SONY logo, followed by a permanent black screen. The screen is on, it is just black.
I scoured the xda forums and I tried several things, to no avail:
I cannot enter recovery mode.
My PC cannot recognize my phone.
Flashtool cannot recognize the phone. My phone can't seem to enter flashmode, either.
I tried holding the power button and the vol. up button, and the phone does indeed restart (no vibrations), showing the SONY logo, and then I'm stuck with the black screen again.
I hope somebody can help me!
EDIT: I managed to somehow get flashmode working, so I think my phone is fine now! What a false alarm! In case this ever happens to anyone, what I did was to unplug the phone from any source of charging, then proceed to hold on the power button and vol. up button for REALLY long, I think almost 20 seconds. This managed to switch my phone off (it would keep restarting if I didn't hold in down long enough).
download stock firmware and open flashtool & ready to flash,dont connect until it say.connect your usb cable to ur phone,then reboot ur phone when display goes to black connect ur phone to pc whith pressing vol down ,then flash tool detect ur phone and it flash,sorry foe my bad english
So the thing is, I decided to buy this phone from another person a few days ago while it was still working but it had this one problem where the owner told me about how the phone can't be shutdown unless the battery runs out of power. Any time you shut it down, it simply reboots instead. I thought it was most likely a problem I could fix after flashing, so I decided to buy it.
Using Flashtool I was able to see that if timed pressing the buttons and plugging it into my computer right before the reboot started, I could boot into flashmode. This phone came in the 4.4 KK firmware and the 10.5.1.A.0.292 Generic NCB build, so I flashed an older kernel and rooted it using Towelroot before reflashing the 10.5.1.A.0.292 Generic NCB kernal. After rooting (and testing if root apps can shut it down which didn't work either), with a locked bootloader I installed the XZDualRecovery using the method here because I was finding it so hard to unlock the bootloader and Flashtool wouldn't do it either. It automatically booted into TWRP recovery menu but when I tried to flash a ROM (existenz Ultimate 3.5 to be precise), it simply made the screen go black for a second and took me back to the recovery menu. So figuring it was a bad download, I downloaded a smaller ROM but when I rebooted I accidentally went into PhilZ Touch menu instead. Deciding to do the usual wipe before flashing, here's where I messed up like an idiot. I saw an option along the lines of "Wipe CLEAN for flashing ROM" or something and trusted it so much despite it saying it's gonna wipe the system partition clean as well (I still don't know why I accepted even when warned of that).
So basically now I have a system that boots the SONY splashscreen and then goes black with the back light still on unless the battery runs out. I can't shut it down no matter how long I hold the power button and if I restart, it boots back to the same thing. I have no recovery menu now thanks to my genius idea of wiping the system, and the only thing I can enter is flashmode. So when I try to flash an FTF firmware (I tried every firmware I could get) back into the phone with Flashtool, it would simply say "preparing for flashing" for about a minute before it says "device disconnected" because the phone decides to exit flash mode and boot normally. I have a locked bootloader (with bootloader unlocking allowed), so I can't flash recovery menus. When I try booting by holding the VolumeUp key and plugging it in, it enters flash mode only with the red LED on and I still get the same results on Flashtool.
Was wondering if there were any ways around this that I might have missed before deciding to open the phone and change the hardware? And if it comes to that, what would I need to change (have always been a software guy when it comes to phones)? Any tips and advice would be appreciated.
TLDR: Have a bricked c6603 from wiping the system, that can't shutdown and keeps rebooting and refuses to be flashed.
If you have time before the phone reboots, hold Volume UP and the power key for 15 seconds. The phone will vibrate once at 10 seconds. Keep holding the keys until you feel 3 vibrations. This will hard power down the phone.

^I've tried this and it simply boots back up again.
Hmm. That should definitely shut the device down, not restart it.
Sounds like there could possibly be an issue with your power button. I've heard of issues with the power button after water damage. Have you checked the water ingress indicators under the flaps? If any are red, it points to earlier damage from water.

Seems like you're right, I just checked it and it indeed has a faded red color on it. Do you think if I take the phone apart it the power button could be fixed or should I swap something else inside this from another Xperia?

I experienced this problem
Pls hold down volume When u connect your phone to pc via flashtool,
It will connect in flash mode
After that , just flash 0.230 kernel via flash mode ( kernel not rom )
Then disconnect your phone
Turn it off ( hold power button and volume up till it vibrates 3 times )
Then before it turn on again , hold down the volume down and connect it to pc via usb and this time flash 0.283 Rom ( not kernel )
This worked for me
