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
Download a known-to-work firmware ftf
Put it into C:\Flashtool\Firmwares
Open flashtool (flashtool64 if you run 64bit Windows)
Chose Flash (flash arrow button)
Chose the ftf you downloaded
Enable "Wipe: Data, Cache, Appslog"
Click flash
A new window opens with a "press back button" animation
Now plug in the device while ONLY holding VolDown. Only VolDown, no Power. The LED should turn green.
Don't interrupt the flashing process. It will take a while.
Report back if it worked.

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).

Returning to stock
Hey guys,
I've flashed [ROM][JB 4.2.2][CM10.1][AOKP-MR1][PananoidAndroid 3.15] PAC v22.1.1 - Update: 0508 from http://forum.xda-developers.com/showthread.php?t=2208249&page=65. It's working, but I'd like to try another ROM, specifically Xperia Z Revolution™ from http://forum.xda-developers.com/showthread.php?t=2175903. This requires to install stock 10.1.A.1.434 firstly So I downloaded C6603_10.1.A.1.434_Generic DE, NL, world. Flashing with Flashtools 0.9.10.1 always stucks at 0%.
BL unlocked. Does anyone have any idea how to get stock 434 in the phone? Originally there were older one 10.1.A.1.340, if it's somehow important to know...
Hello,
Today I wanted to flash a custom ROM and DoomKernel. So first I installed TWRP by downloading the .elf file and installed it via fastboot.
When I restarted my phone it suffered from a bootloop (sometimes a saw the FreeXperia logo). When I pressed the volume-down buttom I managed to get into TWRP. I cleared almost everything (cache, dalvik-cache, factory reset and system).
I wanted to boot the phone to copy the .zip files to the SD-card.
But now I only see a FreeXperia logo I even cannot shutdown the phone...
Do you know what to do? Thank you!!
Keep press power button with button volume UP together for 15 sec,, and phone will shutdown.

If you factory reset and cleared the system you no longer have a working rom installed....you just formatted it.
If you can boot the phone into recovery just flash a rom...
Also, in order to get the files onto the sd card you will have to remove the card from the phone and use a card reader.

Hi All,
I've accidentally wiped all User and System Data using CWM Recovery.
Now, Phone's neither boots up nor goes to FlashMode. It simply hangs at SONY Logo Screen.
I've tried switching off the mobile using OFF Button under the backover, but it reboots and comes and hangs at Sony logo screen.
Urgent help required, Please help.
Thanks,
Shankaran
Did you make a backup of your current Rom before wiping anything?
Sent from my C5303 using xda app-developers app
If u didnt make a backup of your ROM before, u will have to go SONY PC COMPANION and REPAIR YOUR PHONE. In this case, u will lose CWM and root. But nothing u can solve following this incredible forum. Im sorry
Solved

Thanks all.
The problem here was, I was neither able to Flashmode nor Recovery.
The trick to solve this
-- Open Back Panel of the Phone. Locate OFF on the back
-- Connect the Phone to PC, let it hang at SONY logo.
-- Start the Flashtool and Select the file to be flashed
-- Wait for Flashtool prompt to connect the phone in FlashMode
-- Now Press the OFF on the back with the Pen and Hold down the Volume down Button. You should be very quick in this.
-- It goes to FlashMode and Flash Tool starts flashing.

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
