[solved]
tried 5 different cables, 1 notebook, 1 PC, usbdeview uninstalled all others drivers except htc bootloader and still no luck, maybe tomorrow on other 2 cables will be more lucky.
after many tries it worked!
I removed step 1:
fastboot flash radio Radio_HTC_PVT_32A_6.35.10.18.img - THIS NOT DONE 1st time
fastboot flash hboot hboot-1.76.2007.img
fastboot flash recovery recovery-RA-hero-v1.5.2.img
fastboot erase system -w
fastboot reboot-bootloader
then all the rest flashed and then I flashed it again (all the steps):
fastboot flash radio Radio_HTC_PVT_32A_6.35.10.18.img
fastboot flash hboot hboot-1.76.2007.img
fastboot flash recovery recovery-RA-hero-v1.5.2.img
fastboot erase system -w
fastboot reboot-bootloader
with cable that didn't worked earlier.
it is time to flash rom
