Xperia z Reboot loop issue Advice please

So yesterday my phone turned off and has been stuck ever since.

-When plugged into a wall charger it is stuck in a continous reboot loop. It gets as far as the Sony screen then turns off, and repeats.

-When connected to a computer i get a led blink code of red(long) red (quick) green (quick), however i have been unable to locate the meaning of this code.

-If i hold power and volume up i get a vibration and then 3 vibrations then more bootloop (although no response when phone is not connected to a charger)

-Phone was working fine yesterday (no known issues)

-I have tried repairing using sony mobile companion no success

-I have tried flashing using flashtool but no change.

-I am able to enter fastboot mode (solid blue led) and send commands such as reboot and ask for version using flashtool

-I have tried charging by emulating the Sony dock (passed 1.5V from a digitial power supply across the + - terminals)

I am now all out of ideas so any advice would be greatly appreciated.

What if you remove the SIM and SD cards?

I'm sorry to hear that but you will have to contact your Local support to get the phone inspected.
