I updated HBOOT to HBOOT-2.00.0027 and than unlock bootloader through htcdev site.
After that i instaled CyanogenMod 11 Nightlies ROM succesfully and everything works great, except that battery drain fast.
I posted multiply treads because i needed quick answer, because my phone did not work well on previous android version, something messed up with wireless and bluetooth.
Thank you for help anyway.
