hello, i have try everything but cant flash boot image, maybe someone know what i'm doing wrong.

my device:
xperia z c6603
bootloader unlocked
no root
developer options on (adb)

to get kernel.sin i use original firmware from sony emma tool than i use 7zip to extract the kernel.sin,
i also use the androxyde flashtool Tools->Bundles->FILESETdecrypt then extract from .ftf file.
kernel.elf i get with flashtool->tools->sin editor->extract data
kernel.img i get thru rename .elf to .img like here http://xdaforums.com/showthread.php?t=2699858

then i use fastboot devices in cmd.exe (admin) with "fastboot flash boot kernel.elf" also "fastboot flash boot kernel.img"
HTML:
C:\platform-tools>fastboot flash boot kernel.elf
sending 'boot' (9000 KB)...
OKAY [  0.288s]
writing 'boot'...
FAILED (remote: image is not a boot image)
finished. total time: 0.295s

HTML:
C:\platform-tools>fastboot flash boot kernel.img
sending 'boot' (9000 KB)...
OKAY [  0.288s]
writing 'boot'...
FAILED (remote: image is not a boot image)
finished. total time: 0.296s

i also use flashtool for this get same error (see picture)

first i use drivers from sony and xperia companion everything is fine in device manager, i also can erase system, boot and userdata thru fastboot so the drivers are fine.
but for testing i install the driver from androxyde flashtool and done all from begin, same problem here with FAILED (remote: image is not a boot image)

i use win 8.1 64bit as administrator
for install drivers i deactivated the driver signature
can use adb thru cmd.exe (device is correctly shown)
can use fastboot for "fastboot erase boot" for example (device is correctly shown)
i unlocked the bootloader with sony unlock code, no problems

pls help, dont know what i can do else.
