[Q] phone freezes entering the recovery topic

I unlooked the phon on the HTC website and tried to root it. I used DooMLoRD_v2_ROOT-zergRush-busybox-su, DooMLoRD_v4_ROOT-zergRush-busybox-su and a few other images, all with the same result. After flashing the image successfully and entering the recovery the phone shows the white HTC splash screen and freez.

Thanks to DooMLoRD for this easy tool. What do I wrong?
