The mount button is for mounting the card on the phone, which obviously won't work if it's already mounted. You probably want what the UMS button does ;)

I personally would exchange step 2 and 3 (to prevent the computer from auto mounting the card back for whatever reason) , but as long as you do step 1 it should not really matter.

Lol.. Silly me.. Of course that wouldn't work.. Now it's working perfectly.. Your 100th Thanks added.. ;)

Is your extSdCard unmounted? That's probably the problem.

Regards
[Galaxy S III Themes and Apps] roman89:
Thanks for your answer, but i don't think so, because i can use it normaly in android, without doing something.

As mentioned i'm on stock rom and kernel (free austrian version).

I can unmount it manual via settings/storrage. Navigon select is then complaining, that there is no card anymore, but Taskbar tells me, that i can now remove the card.

If I take it out and put it back in, I can see and use it again.

Now using Easy UMS again and pressing UMS mode SU tells me, that it's granted SuperUser rights, but then next: "could not get path of extSdCard".

Well, CM9 is good, but I suppose that author of this app has designed it for stock ROM. I know that CM9 (or any other AOSP/AOKP/MIUI based ROM) do have UMS, but stock ROMs don't. There is reason why even experienced users uses stock ROM.

Hi Kopfgeld,

since today i can't mount my sdcard in UMS mode anymore :(

It tells me that "ExtSdCard is accessed by [,,,,,,,,0].

After restarting it works again but having he phone to reboot for every UMS action is quite sophisticated :(

[Galaxy S III Themes and Apps] gumpelstilzchen:
Wait... It shows that error message exactly like that? That many commas? It should include the application name, but maybe the application that is accessing it can't be filtered the way I did...

Anyway, I'm pretty sure that it not working with that error message is not a failure of the app, because that error message is only shown if unmount fails with "device is being accessed" (not literally, because I'm on my phone)

[Galaxy S III Themes and Apps] shadowk91:
I'm a fan of your work, as it has worked flawlessly and has come in handy so many times. I recently tried the ExtSd2InternalSd just to experiment really as the Apps and games for the S3 are quite beefy, I seem to like it and plan to keep it. The only problem is the Easy UMS will not work and I know it's pretty obvious why. It says "Could not get path of extSdCard" most probably because the ExtSd2InternalSd made the ExtSD appear as the InternalSd. I was just wondering if it would be possible to make an app that could make the physical external sd card show up as UMS with this mod (even though it appears as Internal, and the system is using it so it would probably be silly of me to ask because it probably needs to be unmounted somehow). Sorry if this is a stupid question, just thought maybe it could work somehow?

"Mount card" is for mounting the card on the phone. Did you try to mount it while it was already mounted? You probably wanted what the UMS button does.

I'll have a look at the other problem this evening.

Regards
[Galaxy S III Themes and Apps] gumpelstilzchen:
@roman89

The problem is not that you have no "lun_ex" folder, because you have the s3c-usbgadget kernel module and only one of those is needed. I think there is something wrong with your BusyBox installation (possibly missing some commands that are needed?).

Could you please also post the output of

mount | grep extSdCard | cut -f 1 -d ' '

?

If it says something like "grep: Command not found" or "cut: Command not found", you should (re)install Busybox (I recommend this).

@temasek

Well, it sounds like your sd card is not mounted. Could you also post the output of "mount"?

[Galaxy S III Themes and Apps] gumpelstilzchen:
With the app, not really. But I think you could create a script with Tasker or Llama that uses the commands linked in the OP and is automatically executed when needed.

You have to manually activate UMS and it most probably won't work on anything but a SGS3.

See OP. Reinstall busy box.

Hi, thanks for a great app.

I rooted my s3 and installed busybox (verizon 16g GS3). then I ran UMS and it worked. however, I can't switch it back to MTP mode now. When I hit the button "MTP" and connect, the only message I see is "connect as an installer", but no other response (the computer doesnt show up any new drives, or my device at all).

Any ideas? I did check that I have samsung drivers installed and the fact that ums mode is working says that the cable is working, but I cant get MTP back which i would like to.

[Galaxy S III Themes and Apps] seksmeup:
I'm looking at this line:

mount | grep extSdCard | cut -f 1 -d ' '

The problem when running this command on CM9 or CM10 is that the location of the SD card is not extSdCard. On CM9, the location is external_sd. The location is the same on CM10 iirc, except it also offers sdcard1. The exact location of external_sd is defined as mnt/external_sd. If mount | grep extSdCard | cut -f 1 -d ' ' does not work, the app should attempt mount | grep external_sd | cut -f 1 -d ' ' instead. Either that, or check if the directory exists first.

I understand that and the problem, others have already stated this, but I still would like to see the results to the commands. There are two causes:

2. There have been different reports about where the external sd card location is under CM10.

[ATT I747] works (mostly)

This (v1.5beta) is mostly working for me on a rooted stock ATT I747 (64G exfat microSD) under Linux (Mint 13, with exfat drivers installed). To get it to work reliably, I have to be in MTP mode as default, connect the device (and let it connect in MTP mode), then start UMS mode. The MTP shares then automatically unmount and the microSD card automatically mounts (yay!). Then, after ejecting the drive under Linux and disconnecting, I select Mount card, which remounts the card on the phone successfully. The only problem is that it always checks for errors, suggesting that it's not getting unmounted from the phone cleanly when switching into UMS mode.

If I leave it in UMS mode (i.e., I don't select MTP mode at the outset before connecting), the card never mounts under Linux (and, after connecting, hitting UMS model or MTP mode doesn't help).

That *should* work. There are other applications which might be running at various times and prevent you from mounting your SD Card to USB, it's a process of working out which application is doing it (read the error and if it's not clear which application it is, google the com.<insert name here>).

I'm having the exact same issue. I switch to UMS and the Samsung driver installation pop up comes up,tries to install and fails.

This is on a Verizon, rooted, stock.

Edit: Found this and now it works!

. 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*

15. Go into Device Manager on your computer, right click “SAMSUNG Mobile MTP Device” and select “Properties”

16. Click on the “Driver” tab and click the “Update Driver” button, a prompt will then come up

17. 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

18. Select “USB Mass Storage Device” as the new driver from that list and finish up that install

19. At the end you will see something like this on your computer - Screenshot Here

20. 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
