Step 1: Enable Developer Options
2
Unlike with most regular Android
smartphones and tablets, when you want
to exchange files or data between your
A545/A546-series, F740-series and an
external PC using USB, you will have to
temporality switch the device modem
interface from USB to UART. In order to do
this, you will first have to enable
‘Developer options’. Please go to ‘Settings’
> ‘About Phone/Tablet’ > Tap on ‘Build
number’ seven (7) times. Once successful,
you will read the message “You are now a
developer!”.
