  1. Goedemiddag,
    Ik heb zojuist een Oneplus5T aangeschaft om daarop linux ubuntu touch te installeren en Android te verwijderen. Daarvoor is voldoende softwarematige instructie op internet te vinden. Wat niet te vinden is het antwoord op de vraag: ” Als ik de USB-Configuratie Setting op MTP instelling, om te communiceren de PC en vervolgens de bootloader wil inschakelen dan schakelt Android op dat moment steeds de USB setting terug naar batterij opladen”. Vanuit de Fastboot modus kan ik de USB setting dan niet wijzigen. Zo kom ik dus niet verder met jullie schema. Graag jullie reactie

  2. Ik heb ook een Oneplus5T, waarvan ik de bootloader wil ontgrendelen. Maar zodra ik de fastboot modus inschakel wordt de USB verbinding verbroken. De MTP setting valt terug naar charge. Dan kom ik niet verder, of wel?
