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

Try this: hold power and VolUp for about 15 seconds. The device should vibrate 3 times in a row. It should now be off. Don't plug it in anywhere.
Download the correct flashtool beta for xperia z http://forum.xda-developers.com/showthread.php?t=2162907

Put it into C:\Flashtool\Firmwares
Open flashtool (flashtool64 if you run 64bit Windows)
Chose Flash (flash arrow button)

i will try to flash it using flashtool. thanks for your help mate
had the same problem and i managed to fix it just showing sony sign by installing the sony update programme on the sony update website
all you do is put phone into flashboot mode.
on mine i had to hold up and power button untill it vibrates 3 times then press down volume button to get it into flashboot mode
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
update:
schaggo method works. i can breath now. thanks to @gm007
This worked great for unbricking mine !!
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 ...

They never will. Read the instructions which come with EMMA. I have it working fine, officially, without any credentials.

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).

I am sorry my friend i think that you have entered a bootloop.
Your flashing went wrong but you are pretty lucky that you did not burn the phone's pcb
You can correct this with SUS by going into the update tab and then selecting repair my phone- tablet.
It will download the most current rom for your phone but you will lose all the files stored inside your phone (intenral SD) ,your contacts and your other stuff.
Good luck

8.power off
9.fastboot this kernel

Have you tried to force shutdown by pushing the red/orange button at the back of your phone?
It is done by pushing the button for 5 seconds, after vibrating 3 times, your phone will completely shutdown as if you have removed your battery.
After that, you may proceed to enter fast boot mode and reflash your desired .ftf
I was formating sd card in recovery mode, and then I chose "reboot to system" option, for leaving recovery. The telephone turn off. And nothing more. The battery was about 80%.
The telephone don't react on anything. No power button (or holding power button+volumeUp). If I connect usb charger, it doesn't do anything. If I connect PC via USB, there is no new device in PC. No led blinking.
I tried charging for hole day and night, but nothing changed.
I opened the case (it is just on screw) and disconnect and reconnect the battery. But nothing changed.
So I disconnect the battery again and connect usb. The red LED now blinks every second. And when I'm holding the power button, it doesn't do anything. But it is still the same.. black screen, turned off, no computer connection..
Have you any idea, what can I do? What can I try? Thx

You shouldn't have rebooted into system after wiping it in the first place, because you have no system now. You might try flashing any custom rom's kernel (boot.img) if your device is unlocked. You do it using Flashtool. First copy the boot.img from the rom's zip and paste it somewhere, then select the lightning bolt icon in flashtool, select fastboot mode. Then connect your phone to pc while holding volume + button and keep holding it until blue led lights up. Then in flashtool on the right side choose to flash kernel and select the boot.img you copied from the rom before. After that you should be able to boot into recovery and install any custom rom. If you do not have any custom rom on your phone, you can only transfer it from pc to your microSd card using the sd card adapter and then put the sd card back in your phone.
If your bootloader is NOT unlocked, then you can only try connecting your phone to pc while holding the volume - button until green led lights up. If it doesn't light up, I believe your phone is hard bricked and you can't do anything much. If it does light up, you can download any firmware for your phone in .ftf format and flash it using the same method as described above, but instead of choosing fastboot mode, you have to choose flashmode and select the .ftf you downloaded.

This. I was in the same situation like you just few hours ago. I decided to install custom stock based rom and I rebooted after factory reset. My phone wasn't turning on or anything, just dead brick. I left it for few hours and then I saw that red led was blinking while I was trying to turn it on. So I plugged it into my PC and it was charging (first success). I used flashtool and after many, and I mean it, errors it managed to flash my stock rom.
Now I am stuck at installing CWM v7 but that is another story ; )
hello,
have a c5303 xperia sp and im trying to re-flash the stock rom using flashtool64. the phone doesnt power on but if i hold vol up/down then plug the phone into my pc via usb the respective fastboot/flash mode led colour lights up and it pops up on my computer to confirm it. when i try flash the stock rom, is gives me a error about system.sin, since then i am not able to get into flash/fastboot modes on my phone. as this has happened before (the phone not going into fastboot) im pretty sure i can get it to flash without system.sin then use fastboot to do it after.
the screen is completely blank, not even a backlight. when the usb is plugged in without a mode, it is red on the phones led, when i unplug it and try to turn it on, the red led flashes and nothing happens.
thanks in advance!
fixed it nvm
