no I follow a video to instal the global ROM, i have instaled ADB with TWRP perseus in the same folder. after i have try to instal unzip GLOBAL ROM directly from the phone (I have load it before) but with out success. and Now when i try to instal the zip ROM with an USB key or try lot of other manipulation, i always have this message.
