NOT WORKING: ?
If you have a custom kernel, you have to make sure there is one of the three possible lun files available (see Problems section).
Regarding US versions: Starting with 1.4beta, it also works with US versions (see here). This may not be the case for all variants, so please report back with the information needed in the compability table.
Problems? Not working?
Report the exact problem, model/ROM/kernel/etc., the exact error message and the results of the following commands (use Terminal Emulator or something similar):
mount ls /sys/devices/platform/s3c-usbgadget/gadget/lun0/file ls /sys/devices/virtual/android_usb/android0/f_mass_storage/lun_ex/file ls /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file mount | sed 's/ on / /g' | grep extSdCard | cut -f 1 -d ' '
You may need to replace "extSdCard" in the last command with the mount point name of your external sd card (e.g. external_sd or sdcard1 for CM10)
If the last command does fail, there is probably something wrong with your BusyBox installation. You should reinstall it - I recommend this app.
On some Win7 PCs, these steps may be needed:
Now follow these steps:
1. On your Windows 7 computer you will see it will try to install “SAMSUNG Mobile MTP Device” as one of the drivers and fail *this is normal*
2. Go into Device Manager on your computer, right click “SAMSUNG Mobile MTP Device” and select “Properties”
3. Click on the “Driver” tab and click the “Update Driver” button, a prompt will then come up
4. Select “Browse my computer for driver software”, then select “Let me pick from a list of device drivers on my computer” on the next screen
5. Select “USB Mass Storage Device” as the new driver from that list and finish up that install
6. At the end you will see something like this on your computer – Screenshot Here
7. Windows will install final drivers automatically and a new “Disk drive” will show up on your computer, this is your external SD card on your device
Keep in mind that it is not possible to get access to the internal storage as USB mass storage device.
Get the "extSdCard is being accessed by [...]" message? Wait until the app accessing the sd card has finished, stop it yourself or reboot.
1.8 - added support for third lun file, should work with GT-I9305 (Intl LTE version) now 1.7 - fixed recognition failure if "mount" output contained "on" as the second column (e.g. Siyah kernels) 1.6 - fixed code so that it (hopefully!) works with recent CM10 versions again - made some error messages clearer - drop of "beta" name doesn't actually mean much by the way, but I think it looks a bit cleaner this way and does not make a difference 1.5beta - added support for CM10 sd card paths (/mnt/external_sd and /mnt/sdcard1) 1.4beta - added alternative method for users without s3c-usbgadget (may work on US versions) v1.3beta - rewrote the whole logic - now opens Play Store entry of BusyBox if it is not yet installed - notifies user if device seems to lack s3c-usbgadget module - notifies user which apps are accessing the extSdCard - generally better and more precise error messages v1.2beta2 - added info about busybox requirement (maybe this will be removed later) - added link to donation app v1.2beta - Automatically tries to unmount extSdCard before starting UMS mode. This will fail if some app is accessing it, so just wait or cancel that app if you know it and try again - possibly several times. This prevents the potential data loss with previous versions. - It now checks the location of the extSdCard device. This should help with compabilty, e.g. for US versions. - Added some log output and toasts (2s delay) - Added link to this thread and version number in app - It's a beta so please beware, but I think the worst probable thing that can happen is that it does not work (e.g. it does not start UMS if it cannot unmount the extSdCard). - Dammit, the whole day is already over v1.1 - Added option for going back to MTP v1.0 - Initial release
