Bootlocked unlock is ok.
But then I decided not to reflash stock recovery and just to boot into recovery for once to flash superSU to avoid martyrium caused by getting original recovery (since HTC different retarded versions for every country and every retailer, I am very cautious). I have tried 2 versions of TWRP, one CWM, after "fastboot boot recovery.img" phone boots forever, never finishes, but phonw is fully operational still, so no damage done. I have even tried to reflash recovery in the end, none of them worked. Well, command prompt told me OKAY OKAY, but nothing really happened, like while just booting into recovery. I have even tried several USB cables (happened once with desire X that everything was due to broken USB cable).
I am out of ideas, could please someone point me to some direction of what is wrong?
It runs 4.4.4
