Hi friends ! After installing on Chuwi Hi8 Air single Windows 10 , missing some drivers .( network driver, audio driver , touch pad driver… maybe the most of them ) Unfortunately I lost somewhere the Backup of my drivers and now can’t operate the tablet. Please, someone , who has backup of all original drivers by Double Driver 4.1.0 , send me them ( for CHUWI Hi8 Air ) . Tks !!!
