-fix- Android File Transfer “Can’t access Device Storage”

Open the Developer Options on your Jellybean i9300 and disable “Verify Apps by USB”

“Verify apps over usb — Allows you to disable app checks for sideloading apps over USB, while still checking apps from other sources like the browser. This can speed up the development process while keeping the security feature enabled.”

System: 10.9.2 / Foxhound 1.0 , but it should work with most other Jellybean variants.

  1. Hi Ben,
    Thanks for the tip, but it didn’t work for me. I still get the dreaded message from AFT. When I connect my S4, it opens in AFT, but as soon as I click on the Camera to access my pictures, I get the message that it can’t access my device storage.

    Any other ideas?

    1. Try this (hacky but it works for me):

      save as a script “aft_loves_kies.sh” somewhere in your home directory and chmod it as executable.
      Then run it from terminal like:
      user@machine~ sudo ./aft_loves_kies.sh aft
      …to enable AFT
      user@machine~ sudo ./aft_loves_kies.sh
      …to re-enable Kies.
      This assumes you have Kies on your system.

      #! /bin/bash
      cd /System/Library/Extensions/
      if [ “$1” == “aft” ]
      echo “Enabling AFT, disabling Kies.”
      kextunload -b ssuddrv.kext
      kextunload -b com.devguru.driver.SamsungACMData
      kextunload -b com.devguru.driver.SamsungComposite
      kextunload -b com.devguru.driver.SamsungMTP
      kextunload -b com.devguru.driver.SamsungACMControl
      echo “Enabling Kies, disabling AFT.”
      kextutil -b ssuddrv.kext
      kextutil -b com.devguru.driver.SamsungACMData
      kextutil -b com.devguru.driver.SamsungComposite
      kextutil -b com.devguru.driver.SamsungMTP
      kextutil -b com.devguru.driver.SamsungACMControl
