Trouble installing Wooshbuild


Hi im new to this so sorry if it is something simple. Im following wooshmans guide to flash my H.2S but im having bother. Iv put the zgemma folder on my usb and it seems to flash fine but upon finishing it boots straight to a Channel 5 and doesnt show the Basebuild logo at all. I also cant access the quick launch menu that is pictured in step 2 so i am unable to flash wooshbuild? Help much appreciated. Thanks.
