help wiht MTP/Media Scan?

All,
Finally got JellyBean up and running after a scare with semi bricked phone. Everything was running cool when I started accidentally put .nomedia into the music folder. I realized that, deleted that file, delete data from "Media Storage" service, reboot(thinking that will make phone rescan all the media.
Now, it still doesn't the my music, and when I plug the phone to the computer, all I see is one folder which is the Notification folder. I've had this happen before and I really rather not wipe my phone again.
Any pointers on fixing this?
Thanks!

[Q] Duplicate folders when phone plugged into computer

hey guys,
My issue is that when I plug my s3 into the computer. When I access the SD card from the file explorer on the computer, it comes up with duplicate folders. Just wanted to see if anyone else is having this issue. However if i browse the files through astro on my phone it looks just fine. I'm running AOKP Build 4.

So I saw this & hoped there was some extra infoon tthis topic cause I had the exact same issue. It was agrivating because I didn't know which folder to save to. Some of the folders had different data in them
My solution? I put the sd card in a multi reader & poof - no duplicate files.
BAD NEWS
Now my phone doesn't know where to find the sd card. Oh, it reads & writes just fine. I can see it in SUFBS & Astro file manager, copy files to/from with ease. But go to the gallery & I only see the phone memory. Ring tones are only found in phone memory. Downloading from any Web browser & it only goes to internal storage & I can't point to ext sd, but sms backup & restore saves to it just fine. My friend thinks the drive letter got changed but I have no idea how to find or change that in the phone. I's sad.

Ive never seen this myself. But i only connect to my computer via usb when using Odin. For file transfers i use SwiFTP wireless transfer.
Search for sgs3 easy ums here on xda. Itll let you mount external sd as UMS rather than MTP which is probably whats causing it (maybe because you are non stock?).
Also you may have to reformat the card at this point. Not really sure about that though.
Sorry i dont have more for you, but in the future try those two apps i mentioned. Find Swiftp bt searching the themes and apps section.

[Q] Galaxy Nexus 4.2.1 Can't see all files when via USB (MTP)

I have a galaxy nexus running 4.2.1. I have been having this issue since the update to 4.2. I am not able to see all files when I have my device connected to a pc via USB. When I navigate to the folder on my PC it can be empty or missing the file I am looking to transfer to my PC. I am not sure if this is a 4.2 issue, but I have not have this issue in previous versions. I am able to transfer files via my websharing app, but these files are movies and are over 1 gb in size on average so I would like to get this working. Let me know what you guys think.

Oh I have this same issue on 4.1.1. This is very frustrating. Sometimes, some files even fail to copy to PC.
Overall, the file listing and copy operations from Galaxy Nexus to PC is very unreliable. The file copy was rock solid and even faster on my HTC Desire.
However, I can see all files and copy them successfully using an app called Airdroid, over Wifi.

This issue should not happen anymore after ICS, but try deleting the .nomedia file in your folders, this file tell the phone to not scan in that folder. Reboot, then wait for the media server to rescan, then plug it in.
If that don't work, clear your Media Storage's data (Settings -> Manage apps -> All -> Media Storage), then delete the folder "/sdcard/Android/data/com.google.providers.media", reboot and let it rescan for 10mins.

That did it! Thanks for the info!!!

I am actually still having this issue on my galaxy nexus running 4.2.1. I am running a stock OS and not rooted. I am not sure what else I can do. After further testing I have come to find that I am not able to access any newly created file on my device when connected by a USB cable to a computer until I restart my device. I even went to the trouble of doing a factory data reset. I am able to access new files from my device or wireless via the websharing app, just not via USB to my computer running windows 7 32bit. I am not sure if an app I have installed could be causing this issue. All I know is I never had this issue with ICS. Let me know what you guys think. I am at a total loss with this.

Had same issue not sure of fix but found if i rebooted computer and device when i plug device in again it sees the new files, its like the computer only sees whatever files are in phone at the point of first viewing phone sd folders, so any changes after that arent registered until computer is rebooted.
I think rebooting gnex also helps embed any changes to files and folders.
Its a hassle but it works

Just in the even that someone needs help with this issue. I ended up installing an app called "Rescan Media". All you have to do it tap the icon for this app, you will see a flicker on your phone and your computer will be good to see your new files.

"Rescan Media" app let me see ALL my files in windoZe 7

Magnificent - I've been going crazy wondering why I can't see all my files on my new LG G2 on windows. I followed your instructions and now I can. Thank you.

Loosing media

Hello i recently swapped from ARHD to pabx's [ROM][Feb 8] Jellybean 4.2.1 for Endeavoru AOSP Build [Kernel 3.1.10] #14 but im getting a strange problem sometimes im loosing all the media from my phone (photo's and music). It is still there when i try to mount it from recovery>mount USB.
Before installing the new ROM i wiped the whole sd card and transferred the media files trough MTP,and had no problems with listening to music from the phone until i restarted,then everything went missing. Any help is appreciated.

Hi mate, try this:
Rescan SD
I tell you to do this first as I use this one.
Its not an app, you should just see "Media Rescanned" then check for your music again
If that doesnt work try this one:
Try this second
If not let me know and I'll help further.

Hello and thank you for answering those apps were the ones i first tried,but sadly it didn't work. Any ideas ?

Are you using any different media apps? Like PowerAMP etc? If so, Remove them for now.
Also, as you said, make sure all files show up in PC.
Restart Phone (MAKE SURE FASTREBOOT or whatever its called) IS NOT!!! selected. Turn Fastreboot off.
Restart the phone.
Re Scan media.
Re-check, let me know what happens
Edit (ROOTED) solution:
Another solution is, if your rooted, go to your Music App (In settings) Clear data/cache, Disable the music app.
Restart phone.
Then re-enable music app.
Voila, music should be visible.
(Same applies for Pictures, just follow the steps but for Gallery).

Also simply try holding power for like 10+ seconds. You should see a reboot coming up. This is equal to a battery pull, whereas rebooting from the menu is a simple reboot.

I tried this i even wiped cache. I don't think it is related to the music app itself because even with File explorers like Astro and ES i can't seem to find the media files.
PS: I think the fastboot option is only in sense roms ,im with AOSP and didn't find any option of enable/disable this function.

You may wonder why I have so many resolutions for you, its because I had this issue:
My final idea for you to try, then I'm stumped.
This worked for me, but wanted to hold off as if you have alot of music, it can take a while.
Heres what to do:
Plug device into PC.
Copy Music folder (ALL OF IT, including the actual "Music" folder, to your PC Desktop.
When it has copied to PC, Delete it from the device (yes delete it).
Unplug device
Re-scan SD
Restart device
Plug device back in
Create a new folder named "Music" (CREATE A NEW ONE)
Open the "Music" folder you copied TO your PC.
Copy all the music into your new "Music" folder on device
Re-scan
Restart
Some of these steps may not be necessary (such as re-scanning twice) but DO ALL STEPS.
This resolved my missing music, let me know if it works for you. Goodluck.

Removed all media (music and photos) and added them again (trough Recovery>mount USB) then wiped cache and dalvik cache,rescanned sd and the problem is still there :/ The weird thing is that i get this problem only on Pabx's rom and not on any other. I had this issue on RC 11 then swapped back to ARHD ,now im back to RC14 and the problem is still there.
PS:Btw i reinstalled windows,and when i was seting up adb when i type adb devices i didn't get a list of devices as like there was no devices connected,but when i flashed the boot.img (fastboot flash boot boot.img) the boot.img flashed correctly i got the two OKAY's. Might it be related to this ?

Bah, so your not stock I now find out.
I also feel bad for telling you all these things, when it hasnt helped.
I would re-install ADB/Fastboot, and also add the path to your Fastboot/ADB to your envioronment variables. (Control Panel - Advanced System Settings - Envioronment Varibles)
Make sure you add it to the current list, dont replace anything, it should have a " ; " at the start and end of every variable.
That will make it so you don't have to CD into your fastboot/adb folder in CMD. You can use ADB from anywhere.
Also remove any and all drivers related to Android, just to be on safe side. (They'll be re-downloaded when device is plugged)

Ok it's done i flashed the boot.img, (I don't need to reflash the whole ROM right ?)
Now how should i transfer the music back to the sd card ? Trough MTP or Recovery USB Mount ?
PS:The problem is still there but i think it is because of the big /data partition. For now im going back to arhd. Thank you Wilks3y.

suddenly lost many files and folders from the phone but phone does uses space for it

Please help me. I have many songs, movies and many imp files and documents in the internal storage and suddenly all is gone. Though it shows that it takes the space. Last night I connected my phone to the pc to copy a kernel modules into my phone. I copied and flash and the phone went into bootloop. Then I flashed the previous kernel I was using-ncx and it booted normally. Then I realized many files are missing but the phone is using the space for those. Then o rebooted and flashed the kernle again thinking that it was a kernel issue. After o rebooted I got everything. Then the whole night everything was normal. When I woke up I saw that the same thing happened aagin after a reboot. I rebooted because sound was my playing. It said unable to play media. It rebooted and sound played but the same files where again missing. The I flashed stock kernel. Still the same. Then downloaded viper Rom 3.3.6 and flashed it with and without full wipe and still the same. Please help anyone. I don't have a backup of these missing files and its very urgent.

What happends when you mount the sdcard as a mass storage device inside the recovery ? That way you go around the rom and see the space and hopefully the files directly ! Then at least we can say its a rom problem and not sdcard problem !

I tried that but it shows the same files and folders that it shows inside the Rom.

When you have your phone mounted to your PC.
Control Panel -> Folder Options -> Select "Show hidden files/folders".
See what that does for you.

Did you try to flash a 4.2 rom? 4.2 rom's usually move your data from /sdcard/ to /sdcard/0/ or something, which might explain why you cant see the data when you flashed your previous rom.

When connected to pc and show hidden files. Nothing happens. I already had viper Rom since it released. After copying files from of pc it happened suddenly. I thought reflashing the Rom would solve but no. The titanium backup folder is also gone. The sd card does uses space so I think the files are recoverable. Please help me to recover them. Please.

I found something. The files are still there in the internal storage but not directly in the sd card. It automatically got moved in to a new folder>>> sdcard/0/
Everything is there. How to solve this issue? Make my phone recognize that folder as internal storage or just make it like before?

Lol that happened to me when I flashed my kernel unrepacked. just move everything back to /sdcard

Sdcard/0 is a file structure that happen when you flash 4.2 roms because of the multi user feature. When you flash other roms make sure you copy all files from sdcard/0 to the root folder before flashing
