phone usb not recognised.

Im trying to connect my phone to my computer but when I connect the usb it doesnt allow me to mount the sd card. It just charges but nothing appears in the naotification bar. It used to work fine but now it doesnt let me connect my sd card.

Same problem here, it used to work... but not now. I tryed to uninstall and install again companion but did not solve it

I know that this ain't the solution but you could look into Wifi Syncr as a means to transfer files to your phone.

I can not mount my sd-card with Ubuntu, do I need some drivers and stuff?

Edit: He he he, I fixed it myself by changing to MSC USB-connection.

Go to setting>sonyericsson>connecntivity>usb connection mode change it to mass storage mode.then ur phone will prompt u usb connect to memory card,just select connect.
Happy try.

is it possible force the MTP mode into Mass Storage Device ?

is it possible force the MTP mode into Mass Storage Device ?
as for many users come from Nexus S , Nexus S uses mass storage device to communicate with PC for copy/past/delete files on internal SDcard
i found that it isn't same here on Galaxy Nexus , which uses new mode MTP ...
but i figured out this MTP is little bite pain in ass as i modified files with Root Explorer , but it doesn't show any changes when I try to access internal SDcard with PC to copy/delete files.
even i rebooted my phone twice or thrice , still doesn't show any changes ...
so i begin to miss the old MASS STORAGE DEVICE MODE as we had in Nexus S ...
is it possible to do so ?

If it was possible, it would have been done already. It is not possible on gnex because the sdcard is just a link on the /data partition, which cannot be unmounted while android is running.

There is no way to enable USB Mass Storage. You're gonna have to deal with MTP.

.... well, in that case any possible solutions to what I have described about no showing files change in PC ?

not possible in this configuration. And honestly why would you want to? I certainly do not miss the delay of mount/dismount, also being able to access the storage on my phone at the same time as the connected pc is so much more useful

I don't why and how to say it, for example, I want to mod SystemUI.apk so I copy from /system/app to /sdcard by using Root Explorer, then I connected my phone to PC, but windows explorer doesn't show SystenUI.apk exists in SDcard section while the Root Explorer indicates there is in the SDcard, even I rebooted my phone twice or thrice, it still doesn't show up in windows explorer...
This is what being bother me

i just attempted your exact scenario and windows explorer is now showing systemui.apk in root of /sdcard/, soon as i copied the file using es explorer on the phone i saw my windows explorer window flicker and updated with the newly copied apk. i did this while the phone was connected fyi

Try the app "sdrescan". It'll for android o re "read" the sdcard and populate any changes in it's database.

The implementation of MTP on Android 4.x is buggy. While it seems to work for some people, a large number of users experience issues with file transfers hanging & refresh issues. Forcing a rescan seems to work for the refresh issue.
Personally, I avoid MTP and use ADB for copying stuff. Follow the link in my signature for more info.

lol! try backing up your sdcard using MTP sometime.

This.

I know this thread is old, but hoping someone can help - I cannot find ANY undelete programs for Windows that recognize my GNex. They all require Mass Storage Mode or a disk drive, and even though "Internal Storage" shows up in My Computer, none of the programs see it as a viable location for scanning.
I need to undelete a lot of files from my internal storage (sdcard folder on my GNex). How can I mount this? Or how can I mount the entire internal storage as a "drive" in Windows? I'll put the phone in any mode I have to recover what I accidentally deleted. Can I do it from recovery (mount sdcard perhaps?)

bull****
look at the nexus S. it has built in storage and it used USB mass storage prior to ICS.
it is not a hardware limitation, it is strictly software. google did it so the partition can be EXT3/EXT4 and allow an unlimited amount of storage for apps
the problem with this is, even with its EXT3/4 capability, MTP is ****ing TRASH on linux. i can only send files to my phone, i cant move them onto my PC. i cant move/delete/copy files within the storage.. the only way for me to do it is through a file manager on my phone and even then it doesnt update when i connect to my PC until i reboot my phone a few times.
MTP is a decent technology but mass storage should still be offered. why not have a scalable partition for apps using EXT and allow the rest to be what it wants. i dont know. there are many different ways they could have implemented this internal storage thing but MTP is the worst way (at least for linux)

Nexus S's /sdcard is a separate partition, GNex's /sdcard is just a link to /data/media/0
In other words in with the nexus s the command umount /sdcard works and doesn't with the gnex.

again, not a hardware issue but a software issue.
why can we not partition the internal storage in this way?
the nexus S was partitioned to allow mass storage but with JB it doesnt allow it. it is obviously capable of reverting.
i dont know.. im gonna try to figure something out. ill come back with updates (if i remember to)

Broke my Mass Storage?

Okay so my SD works on my phone, but when i connect to compy it says:
E:\
application not found
I uninstalled a bunch of apps thinking they wernt useful, when this happened.
So what apps are needed for Mass storage mode? Thanks

Well sir. Do you have the appropriate drivers installed on your computer?

Was working fine untill I uninstalled the apps :good:
Re-installed Xperia-NXT light edition and the same problem arises o.o

Yes there is app that allows your pc to detect the android device mass storage. If you need to access to your content inside the sd card you must use an sd card adapter. Otherwise use a CWM backup.

Alright in CWM aswell in Mass storage mode it doesnt work.
ROMS before dont work either.. something with my computer?

I've had driver problems something with the pram in macs. Hard to say but did you backup your phone to a point it once was working?

Did you try a different usb port?

Sonygenmod
Hey all,
So I've been having a problem with Mass Storage mode as well. But I fear my problem may be ROM related. I'm running Sonygenmod, and the only access to my phones sd card is through Media Transfer, which isn't nearly as nice or effective as mass storage. Anybody know what's up?

SD Card and External USB problem

Guys I have an issue with my xperia zl I don't know if this is Rom related or not. When I connect my external usb to my device it deletes most of the files in external usb, same goes to my sd card whenever I add a file in the card it goes away like it was deleted. I am using stock rom 4.4.2 rooted. Any ideas on how tp fix this? I would appreciate the help.

Try using another USB port also remember KitKat utilizes the ext sd differently now look for an app in the play store that would help or on xda.

[Q] can't move files from lg g3 sd card to pc

Hi
I moved acouple of avi files from internal storage to the sd card connected the phone to pc but the files. wont trasnfer over i can see the files on the sd card click copy but when i go to paste the files onto the pc nothing happens. If i remove the card from the phone and use a usb adapter to connect it to the pc the files copy ok.Obviously i don't want to unmount the card from the phone everytime i need to transfer a file to the pc can anyone help me with this

Maybe a formatting error. Sounds ridiculous I know... pointless getting technical, so just wipe the card and see if that fixes your issue

Hi stevepork
I just tried that and its just the same. i was wondering if it might have something to do with kitkat 4.4.2 which the phone is running.

Are you completely stock? Have you frozen or removed any apps/services while trying to debloat?

Hi
The only app i stopped was mcafee security as i had kaspersky mobile security ive had the phone about a month.i tried it again this afternoon and it moved the folder but not the file inside .small files such as srt files will move as well

What is your USB settings ? PTP or MTP ?

Hi
It's mtp when on ptp i just see an image of a camera and have access only to the photos on the phone

What you you see when you right-click on the sdcard file from the computer to show its properties ?

properties doesnt come up only open and explore

Maybe you need this: https://play.google.com/store/apps/details?id=nextapp.sdfix

As I've only had it a month i don't want to root the phone as it'll void the guarantee which I'd have to do to use the app

Dont worry about warranty when rooting.
There is a way to get everything back to normal.

I'm using the folder mount app to move the files to external sd.

I can move files from internal storage to sd card but i cant get them off the sd card without removing it from the phone and connecting it separately to the pc

it's the security measures that prevent unauthorized access to the sdcard. if you don't want to root, you can move your movies to the dcim folder then you can access it under PTP

Thanks alot for that i just tried it and it works a bit slow but better than keep having to take the back of the phone off and on and unmounting the sd card.do you have a link to rooting the g3 I'd like to look into it sp long as its fairly simple and can be reversed

Read this thread for rooting, the unroot method is explained in the second post : http://forum.xda-developers.com/showthread.php?t=2821000

Hi
I rooted the phone and installed supersu but the files still won't transfer to the pc .the phonr id d855 v10h-eur.
