[Q] xperia Z bootloop, noob

Hi everyone, i'm new to xda forums and is complete noob. I recently tried to flash a .434 ROM in order to root my device. I followed the guide posted on (http://forum.xda-developers.com/showthread.php?t=2240614) the forum on how to do so but when i boot the device afterwards i get a message saying my NFC is updating do not turn off the device and the phone restarts and continues on bootloop cycle. Could someone please help me fix this! Much appreciated.

Marshmallow flashtool problem

Few days ago I installed concept marshmallow.Until installation,flashtool couldnt recognize my phone.It says install drivers but I installed it many times but nothing has changed.Now I want to back to older roms.How can ı solve recognizing problem or how ı can install another rom without flashtool ?

Try to use Sony PC Companion and repair your phone via "Support Zone". It may downgrade your phone to 5.1.1 so it's again recognized by Flashtool.

Try to repair software with Sony PC companion, just download it and click on repair software. Did it happened on any game you played and which android version you used?
