Z3 rebooting after 40 seconds in Flashmode

Hello!
My Sony Xperia Z3 (D6603) is rebooting by itself 40 seconds after entering Flashmode so I am unable to flash a Firmware
Does anybody know how to fix this Problem?
I have Firmware 23.0.1.A.5.77 with German T-Mobile Branding and a locked
Bootloader (I don't want to unlock it)
Thanks to everybody in advance

The reboot happens e.g. if no connection established. Drivers installed? Flashtool started to establish flash mode connection?

I installed the drivers from Flashtool
I didn't Start flashing progress
Could that be the cause ?
