I have Xperia S and I have already installed cwm recovery.
I need to use recovery to backup,restore or flash roms from my sdcard.
But every time I have the problem:"E:can'not mount /sdcard".
I have tried to mount it using adb using :
adb shell
su
mount -o mnt/sdcard
I still have the problem.
Can someone help me to use adb correctly to solve the problem or have any better idea.
Thanks
Try to see if this thread on XDA fix your problem.
How to push a file from computer to an Android device having no SD Card in it. I tried:
C:\anand>adb push anand.jpg /data/local
3399 KB/s (111387 bytes in 0.032s)
C:\anand>adb push anand.jpg /data/opt
3199 KB/s (111387 bytes in 0.034s)
C:\anand>adb push anand.jpg /data/tmp
3884 KB/s (111387 bytes in 0.028s)
Above commands to move a file anand.jpg to a device but I didn't get this jpg file in the device.
I didn't get any success result on cmd prompt, I only got:
3399 KB/s (111387 bytes in 0.032s).
From Ubuntu/Mac Terminal, the below command should work.
./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/'
For adb v33 and above if you are getting a permission denied error, try what I tried. The following command and it works fine.
The only caveat is you might need to use tmp directory on such an emulator.
adb shell //Entering into shell
su //Super user mode
chmod 777 /data/local/tmp/ //Grantint RWX access
exit
chmod 777 /data/local/tmp/ //Grantint RWX access
exit
And then try
./adb push '/home/hardik.trivedi/Downloads/one.jpg' '/data/local/tmp/'
I did it using the push command, which has syntax:
adb push filename.extension /sdcard/0/
Example of copying directory, and sub-directory content:
adb push C:\my-location\data\. /storage/emulated/0/Android/data
Note that push did just hang in latest platform-tools (33.0.1, at time of writing) for a certain amount of files, beside the adb.exe suddenly taking 5MB+ instead of 1.5MB, hence I just did replace the adb.exe with one I had from 28.0.0 version of platform-tools (I did not downgrade the entire platform-tools, because adb.exe is kind of stand-alone).
I don't say there is any conspiracy around data folder,
But my Samsung device puts limits on my USB file transfer, beside Android v11+ not allowing access to data folder anymore, hence I needed above command to work with 100% speed (without hanging one hour for little more files).
Follow these steps :
go to Android Sdk then 'platform-tools' path on your Terminal or Console
(on mac, default path is : /Users/USERNAME/Library/Android/sdk/platform-tools)
To check the SDCards(External and Internal) installed on your device fire these commands :
1) ./adb shell (hit return/enter)
2) cd -(hit return/enter)
now you will see the list of Directories and files from your android device
there you may find /sdcard as well as /storage
3) cd /storage (hit return/enter)
4) ls (hit return/enter)
you may see sdcard0 (generally sdcard0 is internal storage) and sdcard1 (if External SDCard is present)
5) exit (hit return/enter)
to come out of adb shell
6) ./adb push '/Users/SML/Documents/filename.zip'
/storage/sdcard0/path_to_store/ (hit return/enter)
to copy file
Sometimes you need the extension,
adb push file.zip /sdcard/file.zip
run below command firstly
adb root
adb remount
Then execute what you input previously
C:\anand>adb push anand.jpg /data/local
C:\anand>adb push anand.jpg /data/opt
C:\anand>adb push anand.jpg /data/tmp
After Trying all the answers this worked for me
Where I am Pushing a file on Desktop to Android Device (Redmi K20 pro) connected Over the air using adb.
This command pushes the file to the downloads folder on my phone
adb push ~/Desktop/notifications.drawio ./storage/emulated/0/Download
after running this if you get a permission denied error
try running these commands in order (which basically changes the directory permission)
adb shell
chmod 777 /data/local/tmp
exit
and then run try the adb push command
I have documented this here feel free to share your views and help improve it.
Try this to push in Internal storage.
adb push my-file.apk ./storage/emulated/0/
Works in One plus device, without SD card.
My solution (example with a random mp4 video file):
Set a file to device:
adb push /home/myuser/myVideoFile.mp4 /storage/emulated/legacy/
Get a file from device:
adb pull /storage/emulated/legacy/myVideoFile.mp4
For retrieve the path in the code:
String myFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myVideoFile.mp4";
This is all. This solution doesn't give permission problems and it works fine.
Last point: I wanted to change the video metadata information. If you want to write into your device you should change the permission in the AndroidManifest.xml. Add this line:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I've got a Nexus 4, that is without external storage. However Android thinks to have one because it mount a separated partition called "storage", mounted in "/storage/emulated/legacy", so try pushing there: adb push anand.jpg /storage/emulated/legacy
As there are different paths for different versions. Here is a generic solution:
Find the path...
Enter adb shell in command line.
Then ls and Enter.
Now you'll see the files and directories of Android device. Now with combination of ls and cd dirName find the path to the Internal or External storage.
In the root directory, the directories names will be like mnt, sdcard, emulator0, etc
Example: adb push file.txt mnt/sdcard/myDir/Projects/
This might be the best answer you'll may read.
Setup Android Studio
Then just go to view & Open Device Explorer.
Right-click on the folder & just upload a file.
In Mac: To push files via adb
adb push /Users/Downloadsâ©/amazon.sdktester.json '/mnt/sdcard/amazon.sdktester.json'
You are trying to write to system folders. With ADB you have root (admin) access so you see the system folders of which sdcard is one of them so to send a picture you could use
D:\Program Files\Android\sdk\platform-tools\adb push am files\android sdk\adb.exe push C:\Downloads\anand.jpg /sdcard/pictures/
NB: C:\Downloads\anand.jpg replace with path and name to picture..
Certain versions of android do not fire proper tasks for updating the state of file system.
You could trigger an explicit intent for updating the status of the file system.
(I just tested after being in the same OP's situation)
adb shell am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///
(You could pass a specific filepath instead of file:/// like file:///sdcard )
In my case, I had an already removed SDCard still registered in Android.
So I longpressed the entry for my old SDCard under:
Settings | Storage & USB
and selected "Forget".
Afterwards a normal
adb push myfile.zip /sdcard/
worked fine.
To push all the files at your directory to the Android device use:
PS D:\myFiles> adb push . '/data/local/tmp/'
My problem is i can write files on sd card in emulator but i find the solution to this problem in stack overflow here to implement that you have to add a group media_rw under android.permission.WRITE_EXTERNAL_STORAGE in platform.xml so for i successfully pulled the xml file but after editing the file i can't push that file so when i am pushing it gives the below error
[Java is awesome]:~$ adb push platform.xml /system/etc/permissions/
failed to copy 'platform.xml' to '/system/etc/permissions//platform.xml': Read-only file system
to overcome this i remount the adb and again i tried i gives the below error
[Java is awesome]:~$ adb remount
remount succeeded
[Java is awesome]:~$ adb push platform.xml /system/etc/permissions/
failed to copy 'platform.xml' to '/system/etc/permissions//platform.xml': Out of memory
so how can push the file or is there any alternative that can enable editing of file with in the adb shell
Thanks in advance
You need to increase the /system partition size accordingly to account for the extra bytes in the file:
You can do this with the following command:
emulator -partition-size <size>
Where is the size depends on your system image plus the extra bytes.
My sdcard permission is now d---------. How to change the sdcard permission as drwxrwxrwx. I need help. Please give me any one answer. Thanks.
Go to android sdk Manager and cllck edit button on your current emulator.check whether you mention the sdcard memory
commands..
$ adb shell
$ su
$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Try this and let me know what happen..
go to Android virtual Device manager->Edit->Hardware->new->sdcard support
You need be root to acheive this. If you need it in emulator grab a rooted emulator , you can find one here.Then you can use the Terminal Emulator for giving permission or if you don't want to write any command just install the rootexplorer app and use it for giving permission.
I use a Samsung Dart - SGH-T499 with Android v2.2.2 on it.
Now I need to edit the /system/etc/bluetooth/audio.config file. For that I rooted my phone using the SuperOneClickv2.3.3-ShortFuse. And browsed the file-system using Root Explorer. But I am unable to edit the permission of the audio.config. Could you please help me?
You also need to ensure that the /system directory, as it's a filesystem, is mounted read-write. In the adb shell use -o rw,remount as parameters to the mount command to do this. First you need to determine what ( hardware / physical / logical ) device that particular filesystem is stored on - use the mount command on its own to see the list and select the one which has /system as its mount point.
Can you not issue a
chmod 777 /system/etc/bluetooth/audio.config
...from the adb shell?
