[APP][v1.8 (+US)] SGS3 Easy UMS - Mount external microSD card as USB mass storage

[elcoxx]

Does not work on my i9300 CM11 (KitKat 4.2.2)

 

[ansikone]

Nope on omnirom.

It worked on stock and i think cyanogenmod on my i9305, but ever since I installed omnirom, it hasn't been able to mount it.

Error toast when pressing UMS mode:

"Could not get path of external sd card (extSdCard/external_sd/sdcard1). Maybe it's unmounted?"

Error toast when pressing Mount card:

"Could not mount card.[1]"

First lun file exists.
the second command with the grep, doesn't output anything on terminal emulator.
With ES file explorer I can see that there is a link in my root called "extSdCard" and it takes to the right location, at /storage/sdcard1.

This is internatinal i9305 (LTE) with omnirom 4.4.2-20140124-i9305-NIGHTLY
Baseband I9305XXBMH3
Kernel 3.0.64-CM-g87d4016

I am also trying to access External SD via USB.

When I am trying to mount card in application I receive "Could not mount card 1"

When I clicking UMS mode button I receive" Couldn't get path of external card extsdcard/external_sd/sdcard1. Maybe it is unmounted"
although eternal card is visible and accessible in system

Please find outcome of mount command:

Ok tried the S3 one with my Sprint SG3 and it still only detects as a CD Rom so can not write to it can only read from it so still unfortunately useless. I really hope you get this CD Rom detection fixed so that I can use it again as a mass storage device.

Android 4.3 version

Very Good

This app is Very Good
Thank you so much:good::good:

 

[djgius]

hello. I have a problem: I have a samsung galaxy s3 and a Sandisk micro sd 64 gb. When I connect my cell to pc and try, with this app, to start the UMS mode the app gives me the error that "the memory is not mounted". Why? the memory is mounted! how to solve? Thank you

This worked for read and write on my galaxy s3 i9300 ParanoidAndroid 4 BETA 1

 

[XeoNoX]

i had today tested following was based on this: http://forum.xda-developers.com/showpost.php?p=39342162&postcount=10

for our S4 it use this to change to Mass Storage in Terminal Emulator (if that fine works we can made a Script for S.Manager to use as Widget:


Steps:
Disconnect Device
now open Terminal Emulator and enter:

su
setprop persist.sys.usb.config mass_storage,adb
echo /dev/block/vold/179:33 > /sys/devices/platform/msm_hsusb/gadget/lun0/file

Connect Device with your USB-Cable

You have now Access to the external SDCard


Internal SC-Card will not work

this works too on stock s4 rooted with kitkat...worked on my tmobile phone

HI

Does not work on my CM11T.T

 

[joebloggscity]

Does not work on my CM11T.T

I need help.

I've an S3 which has been rooted (checked root is fine with Root Checker).

I used to use Easy UMS to get to use the external SD card like a USB stick.

However, my phone was updated to 4.3 and since then it doesn't work.

Keeps saying extSD card not mounted, cannot find path etc.... Never seen taht before.

I tried out and installed the apk USB Mass Storage Enabler and good news that my PC can see two drives E & G. However each time I click either of the disks a message comes up saying "Please insert a disk into Removable Disk (G".

Does anyone know what I'm doing wrong? how do i fix this.

Please help.

Did you try to: open the notification bar, a line with USB shoud be there, tap on it and you can activate de USB

Tilagoon

thx for the reply.

In my hpne the "USB" line doesn't show. The two boxes for MTP and camera upload are unticked.

I've found a sort of work aroudn but it's clumsy

1) go into settins and unmount the SD card

2) then run the USB Mass Storage Enabler

3) this should give access to the SD Card

4) on finished go back to settings and mount the card

5) Restart the phone

Cumbersome and if the developers can help sort this out, that woudl be great.

does anyne know or can make this work on note 3

thanks

UMS with Galaxy S5 (SM-G900F)

I was happily using "Easy UMS" with my previous S3. But now I can't get happy with my great new S5: neither "Easy UMS" nor "UMS Enabler" work for me. With "Easy UMS" I get the unfamous

Could not get path of external sd card (extsdcard/external_sd/sdcard1). Maybe it´s unmounted?

.
With "UMS Enabler" I first get an error

An error occured while identifying the SD card. The card is either not ready or there is no SD card inserted

Trying again seems to work and says "Current State: Mass Storage" but in Windows I only see an empty CD-ROM drive (as reported several times before).

Is anybody willing to help me to find the "magic words"? Here is my debug output:

Thanks man

this works great on CM11.0 (SNAPSHOT-M6)

 

[GuyInDogSuit]

I couldn't get this working with my SM-G900T, either. Bummer, because I just bought a new car stereo deck specifically for this.

 

[GNJF]

I get random disconnects sometimes when I am in UMS mode, it goes away for a second and reconnects but it won't allow me to delete or transfer anything until i mount the card and try UMS mode again

Same here, and no replacement solution...

All I get is "External card not mounted.... could not get path of external SD card. Maybe it's unmounted?"
