Usar o APKPure APP
Obter o APK da versão antiga de USB mode switch for SGS1 on CM para Android
Seja Mass Storage montagem de trás (apenas para dispositivos antigos)
This miniature app is to change your usb mode from MTP to mass storage and vice versa.
The app was made for CM9 users on the Samsung Galaxy S. It is reported to work on the Samsung Galaxy S2 and the Samsung Galaxy Note as well.
It does NOT work on the Samsung Galaxy S3 and most likely it will not work on the Samsung Galaxy Note 2 also. All devices tat came shipped with Android 3.x and above will not be able to run on mass storage, unfotunately I can only block lower api's, not higher api's on the play store.
