here simple application that will enabled UMS mode for External sdcard
root needed.

how to use:
safe way on version 2.5 is :
enable UMS Mode when cable usb is unplug
Back to Charge mode when cable usb is unplug

safe way on version 3.0 is :
do it on condition usb plugged

note:
if you plug into player or some device player , and you found that it cannot found the USB drive
in this case just do this
settings -> connectivity -> usb connection type
and do press or repress the "Charge Only"


in version 3.0 you will notice 1 triangle on task bar, its normal , it telling you mass storage is currently unmount
2 icon on task bar is telling you the mass storage successful unmount you can take it out
those of notice are normal if we do unmount the mass storage in android api level.

all the information about how to do it i found on XDA forum.
i do some research also code this app

version 2.1
fix sometime fail to mount back to external_sd folder

version 2.5
fix sometime got to bluescreen on windows

version 3.0
fix bluescreen on windows
using different approach to unmount the external SD card

version 3.2

It does not mount back SDcard to /mnt/sdcard/external_sd after disconnect, so have to reboot after use it.

MTP is working but external_sd is empty.

With the first version I have access to the card. After disconnecting I have to reboot the phone, so I can regain access to the card.

try the version 2.1, i fix it
Version 2.1 gives reproducible blue screens with Win7 x64 SP1 at the first link when I confirm the superuser, or in further tries, when connect the USB cable.
Only uninstalling the apk helps to solve the problem. :(

A little off topic:

After UMS_mode.apk does not work for me, here is another way to access both memory cards in the P880 (and any other Android-Device) from Windows OS:

Install Total Commander (Shareware): http://www.ghisler.com
Install Total Commander Plugin "Android ADB" (Freeware): http://www.totalcmd.net/plugring/android_adb.html
Android device driver has to be installed too!

Through links, both SD-Cards appear with 3 differen pathes in the P880 operating system.
The external SD-Card has its mount point in (!) the internal SD-card:
Code:
Internal SD-Card:
\\\ADB\LG-P880\data\media\
\\\ADB\LG-P880\mnt\sdcard\
\\\ADB\LG-P880\sdcard\

2. external SD-Card:
\\\ADB\LG-P880\data\media\external_sd\
\\\ADB\LG-P880\mnt\sdcard\external_sd\
\\\ADB\LG-P880\sdcard\external_sd\

Wow!

This is the greatest thing created for this phone so far.

MTP is painfully slow, doesn't work with cars/stereos/etc, requires installing drivers everywhere I go, crashes all the time, doesn't allow access with a file path, and somehow caused my sd card to wipe itself three times in two weeks, so this was a major issue for me that was making me regret buying the phone.

Initially after installing this app (v3.0), I had to repeatedly toggle UMS/MTP mode and plug/unplug my phone from the computer several times before it finally started working, but now it's perfect.

If you have a paypal or flattr link, and I'll send something your way. Or put it on the Play Store so I can buy it and update :)

Thanks!

I can not confirm unfortunately.
I wanted to give the app still a second chance and have installed 3.0.
Then I restarted the phone, without starting the APP before.

Now it hangs on startup LG boot logo.
Even without the second SD card the same problem. :(

Any idea without factory reset or flashing KDZ? :confused:

My phone is still stuck in boot, but I have an access via adb shell to system.
Unfortunately I have no permission to access "/data"

Could anyone tell me the aplication name of this UMS-Tool under "/data/data" ?

I only found "com.noshufou.android.su" in classes.dex, but don't know wether this is right:
Code:
[email protected]:/data $ run-as com.noshufou.android.su
run-as com.noshufou.android.su
run-as: Package 'com.noshufou.android.su' is unknown
[email protected]ndroid:/data $

Ok, I guess it's not quite working perfectly for me now that I've used it a bit more, but I still love it.

1) it's really tricky to get it working initially. I almost always have to toggle it multiple times and sometimes reconnect the usb cable.
2) like someone else mentioned, it never remounts the SD card so I have to restart the phone to get it working again after I'm done.

I have not had any problems on boot like BudCord.

I'm running stock firmware 10f.

Any chance to get it working on mac os x (10.6.8) ?

For the moment it is the only default i found with this phone : the lack of "connections" with Apple's OS :/


PS : I searched on the web and I found a solution for Mac OS X users : Android File Transfer (on the official website).
Sorry I can not the url because I am new on this forum.
