How do I Unmount from Cyanogenmod 12? - General Questions and Answers

just installed Cyanogenmod 12 on my Galaxy Nexus GSM. I have given my Filemanager Superuser Access. I can now connect a USB Drive using a USB OTG Cable, and I can see it mounted under /mnt/media_rw/usbdisk.
Is there anyway I can unmount this USB Drive after I have finished working with it? (Obviously other than shutting down the phone?)
Thank you,
O. O.

If the device requires unmounting it, there will a setting to unmount it in system settings>storage somewhere. If it doesn't have that then it might have a notification in status bar that you pull down that has USB options. If you don't see one of these options then just disconnect it.

Thank you. Before I go ahead, I would like to point out that I'm using Cyanogenmod 12 i.e. Android 5.
Just after I plug in my USB drive, I get a notification of a USB connection at the top, but it goes away before I can click on it. My drive functions fine. There is nothing under system settings>storage other than a table of the disk usage i.e. no place to unmount it. If I just disconnect it, I get a warning triangle at the top with the note: USB Storage unexpetedly removed Unmount USB storage before removing to ...
Is there somewhere I can go to force the unmount?

Lollipop should have the pull down USB options or Mass Storage options.
You can also power the device off then disconnect.
You can also install the StickMount app by Chainfire, it has a mount/unmount feature.
Or you can get technical and use Terminal Emulator commands.
@O.O did you see what I added to this post?

Shutting down the device is what I do. StickMount (free version) does not seem to work (I allowed it to install the downloads that it wanted) and I restarted my phone. I do not get my drive in the mounted devices, and when I click UnMount, I get "The mount service is busy - try again in a few seconds"
I'm not sure if I can get the Terminal Emulator to work.

When you use Stickmount, have you given it superuser permission and are you using it to mount the OTG? It probably has to be the one to control mount and unmount, you can't let android system mount then unmount with StickMount. This is probably why you are getting the "service is busy" message.

Thank you.
I have used Stickmount before, so I understand how it works. I also understand that I need to let it control the mount and unmount, which right now is controlled by the OS. However, this question is about the OS, not about StickMount. If there is no way on the OS level, which does the mount automatically, I think I would have to settle with powering down my device.

I've looked around and I don't see anything as a workaround as far as the OS goes.

DSLR Camera USB input

Can anyone tell me if rooting will make this possible?
I want to be able to plug my DSLR camera directly into the USB on my Xoom and download the pictures. Is this possible if I root and use the new Tiamat Kernel?
Thanks,
I don't think tethering a camera has been possible on any android device yet.
You cant control a DSLR but it might mount as an external drive. Havent tried it myself yet, need to order to right cable or adapter.
I have the adapter on the way. And yes, I didnt want to control it, only mount the CF card in the camera so I can access the pictures.
Yeah the only way I've found to accomplish what you are trying to do was to use an external USB card reader, which (assuming you have rooted and performed the USB host hack) you can plug into the xoom (via adapter) and read the CF off of the card reader. In order for the camera to connect directly to the Xoom, I believe the Xoom would have to have drivers for the camera itself (though I could be wrong, but either way that method doesn't work as of now).
without the drivers installed on my pc my camera acts like a usb card reader
Can someone walk me through how to mount mass storage? I am trying to hook up my camera so see the photos on the SD cardof the camera. I am rooted using the tiamat 1.4.0 kernel. I have hooked it up with my cable adapter and checked usbOTG, external, and sdcard2 but none of the files show up there. I rebooted and still nothing. Do I need to run a script fro it to show up?

Motorola has a USB camera accessory (and pending software update) to enable PTP which will likely do watch you need. Coming very soon. No rooting required.
See this thread: http://forum.xda-developers.com/showthread.php?t=1054636
I have read the mounting USB storage thread and followed the directions exactly but I am having issues. I posted in that thread this same question but it doesnt seem to be getting any attention so I figured i would try the same question here as its all related. I am trying to access the CF card in mt camera but i cant get the script to work.
gscript continues to give a permission denied error everytime I run either script even though I have chmod'd all files and folders.
mount -o remount,rw /

ln -s /mnt/ntfsdisk /ntfsdisk
ntfs-3g /dev/block/sda1 /mnt/ntfsdisk
scriptor says:

failed to access /dev/block/sda1 please check dev/block/sda1 and the ntfs-3g binary permissions and the mounting user ID
do i need to do anything from the roebeet page if i am already running tiamat 1.4.0? All i did was follow the instructions from the first post of this thread.
I was able to plug in a 2gb thumb drive and see it under the OTG folder. Still no luck mounting a NTFS drive though.

Buy an Eye-Fi card for your camera and download the eye-fi app for your xoom. once the two are paired, every new photo you take with your camera will appear on your xoom over wifi. No cables needed.

You can find a great app in the market called "DSLR Controller". Currently only works with Cannon DSLR and requires root, but allows full control and live preview of your camera right on your xoom. It's Awesome !

[GUIDE] Enable UMS Mode for External SD Card ***UPDATED***

I have recreated this method based on this post to make it much easier for everyone to get this setup on their devices with complete details.
Confirmed Working With
1. Windows 7
2. Mac OS X 10.6 (Snow Leopard)
3. Mac OS X 10.7 (Lion)
4. Other OS versions possible just not yet confirmed/tested (only thing stopping is driver support)
How to Enable UMS Mode on your Verizon Galaxy S III
1. Make sure you are currently rooted ***VERY IMPORTANT***
2. Download and install the Samsung Official Verizon Galaxy S III USB Drivers - Link Here
3. Download and install GScript Lite from the Play Store onto your device - Link Here
4. Download the Verizon Galaxy S III UMS-MTP Switcher Scripts to your computer - Link Here (or attachment at bottom of OP)
5. Create a folder called "gscript" on the root of your internal storage (/sdcard partition)
6. Extract the two scripts from the zip file (from step #4) into that folder on your device - Screenshot Here
7. Open GScript Lite on your device
8. Press the Menu key on your device and select "Add script"
9. Press the "Load file" button and select "UMS Mode.sh", then press the "Save" button and the UMS Mode script will be added to the list
10. Press the Menu key on your device and select "Add script" again
11. Press the "Load file" button and select "MTP Mode.sh", then press the "Save" button and the MTP Mode script will be added to the list
12. Select the "UMS Mode" script from the list and allow Superuser for root access
13. The script will now run and do not worry if GScript Lite force closes at the end as this is perfectly normal
14. On your Windows 7 computer you will see it will try to install "SAMSUNG Mobile MTP Device" as one of the drivers and fail *this is normal*
15. Go into Device Manager on your computer, right click "SAMSUNG Mobile MTP Device" and select "Properties"
16. Click on the "Driver" tab and click the "Update Driver" button, a prompt will then come up
17. Select "Browse my computer for driver software", then select "Let me pick from a list of device drivers on my computer" on the next screen
18. Select "USB Mass Storage Device" as the new driver from that list and finish up that install
19. At the end you will see something like this on your computer - Screenshot Here
20. Windows will install final drivers automatically and a new "Disk drive" will show up on your computer, this is your external SD card on your device
21. If you want to return to MTP Mode, just select "MTP Mode" script from GScript Lite on your device and after it force closes you will be back to normal

Benefits of UMS Mode
USB Mass Storage (UMS) Mode used the old way of managing USB storage (like Galaxy S II and so on) before that changed to Media Transfer Protocol (MTP) Mode (aka. Device mode) with the Samsung Galaxy Nexus. The benefit of UMS Mode is that it will work with special devices that try to read your phone like a car radio head unit will now be able to read the songs, pictures, videos, etc through the USB port properly, as well as your TV (if it has USB support of course), among many other devices. Also it's a much more reliable method of transferring files on your computer since it's basically direct access to the SD Card as opposed working through a special protocol with MTP or PTP Mode. This mod will enable your SD Card to show up as a regular disk drive instead of a device on whatever you plug into with a USB port. Hope that helps explain it a bit without being too technical. For details on why Google decided to switch to MTP Mode see this article.

Awesome, sweet write up. :good:
I may have to try this. The MTP doesn't work on my Mac for some reason. Android file transfer just crashes whenever I try it.
Do you have to enable the script at boot?
Explanation in OP very summary.
Plug the phone where? In the computer or the AC adapter?
If in the computer then why is necessary that to run the script.
If you don't use the GScript Lite then what do you use to run the scripts (Terminal?).
If you copy the script to the phone then the files should have which extension? I mention that because there is nothing attached.
Do not forget that you're dealing here with a lot of noobs.
Please be so kind and review the OP.
If the script works correct then this is a big deal and I congratulate you but do it like a pro.
Cheers.

I just tried it and it works perfectly.
This part is very important:
If Windows fails to find the correct driver, go to the Device Manager and manually set it to use the driver, "USB Mass Storage Device". It seemed to try to stick with the MTP driver in my case.

OK here is what I did.
Installed Script Manager free from the market.
Copied both scripts into sdcard\scripts folder.scripts folder created by myslef.
Opened the mass storages.sh script and run it.
I've got bunch of error messages that it cannot find this and that.
The phone was connected to the computer.
If necessary I can screenshot the errors.

Don't use those scripts, I have issues with them as well. Just copy/paste the OP text into your own script using GScript Lite.
OK let's try. I'll report back.
Edit: OK I did what you proposed. Created the script in GSript Lite and saved then ran. Nothing happens. After I run it GScript FCs. I'm giving up.
This is so simple that I don't think that I'm messing up something.

GScript does have force close issues but don't worry, it still runs as long as you don't see any errors when it's done.
I have just extracted the working GScripts I created and added them to OP for anyone who wants to import them into their GScript Lite. Just create a folder called "gscript" on your internal memory "/sdcard" partition and put those two .sh files into that folder. Then just use the app to add each of them as a new script (load file).
If Windows fails to find the correct driver, go to the Device Manager and manually set it to use the driver, "USB Mass Storage Device". It seemed to try to stick with the MTP driver in my case.

So what does this enable you to do? Browse the entire internal memory when connected to USB, opposed to just the microSD?
This will enable your SD Card to show up as a regular disk drive instead of a device on whatever you plug into with a USB port.

[Q] CWM Recovery Red: Access hidden files SDCard?

Hello everyone and thanks in advance for anyone replying to my dumb question.
Today I was preparing to use the Aroma Toolkit to restore my phone to a basic stock. I placed it in a folder called ".rom" on the internal sdcard so it would appear at the top. (can you believe it?) I have CWM Red and it doesn't see ".rom" as it is now hidden. (I guess) Unfortunately, I already wiped AND formatted "system" so I can't boot the phone up to change the folder to something more sensible. I cannot restore from Odin OR Heimdall because my phone won't show up on ANY PC and it only shows "Unknown USB Device." I've been up and down with that one too. Also, I tried to put the toolkit on the external sdcard both as is and as update.zip but it says there are no files. I think my only way(s) out of this would be to Odin or Heimdall, if I can get either working again, or if there is a way to get the CWM Red to see that hidden ".rom" folder.
ANY help at all would be greatly appreciated.
Thanks for reading this.
folders and files that begin with a dot are hidden in linux systems like android. you are seeing an unknown device because you dont have samsung drivers installed. you should be able to go into mounts and storage and select usb mass storage or something like that and it will mount as a mass storage device where you can rename the file in windows where that doesnt show as a hidden file.
if you wiped system, if you turn off your device, you might not be able to get back into recovery and youll have to use odin or heimdall. you can download the samsung drivers from http://d-h.st/xEG and when you are in recovery mode, go to device manager and select from the list of device and choose samsung composite device or something like that i dont remember.
next time you want a folder to show at the top of the list, i think you can start it with an underscore. i could be wrong about that though. you can try it out and see.
I don't recall if red CWM has the mount as usb storage option. If not...
Next step is getting the drivers on your PC. Easiest option from there is Odin or Heimdall - unless you want to download the android SDK and use adb shell to rename the directory.
Underscore should work for sorting...
fwiw I use exclamation points.

Thanks for the reply! Although I did have the Samsung drivers installed with Kies mini, I removed Kies and installed the drivers in the link you gave me but no luck. USB used to work fine in Win as well as Lin but it stopped suddenly. I am able to get into both recovery and download mode fine but I can't go anywhere from there. I tried to "mount sd_ext" under mounts and storage in recovery, hoping to access the aroma toolkit file from there, but I get a can't mount error that says /dev/block/mmcblklb1p2 (file exists). "mount USB" doesn't help either. I really did it this time....
Thanks again for the input
well, if youre not going to download mode to run odin, and you cant do usb mass storage in red cwm, and you want to do it from recovery, you need to choose samsung adb device in device manager. then you need adb and can do adb shell and run "mv /sdcard/.rom /sdcard/_rom"

sd_ext in red recovery does not refer to the external sd card (even though you would think it does from the name)
For compatible drivers, remove all Samsung phone related drivers from your system and install the first driver package located here (not the mini-kies one):
http://www.samsung.com/us/support/owners/product/SGH-I997ZKAATT
Some things that may help:
http://forum.xda-developers.com/showthread.php?t=1982306&page=2
Also, turn off auto driver install in Windows 7 - could be your PC is deciding what is best for you before you can install working drivers:
Go to Control Panel > System > Advanced System Settings > Hardware > Device Installation Settings > "No / Never"
Then install the driver, then connect your phone. Once the driver and devices are fully installed you can change the above setting back to what it was or to "No / Install" (that's where I usually leave it)
Good luck
Well I sincerely appreciate all the help from you guys, and Zen Arcade, thanks for the toolkit that brought me back from disaster quite a few times. I tried all of your suggestions, but it seems like I might have a hardware failure which occured before all this. I was able to connect to USB fine and out of nowhere it just wouldn't anymore. That was OK. I still rom-hopped along with straight to phone rom aquisition, but then I made a mistake. One I have learned from. I'm not able to get the phone to show up AT ALL. I even tried a clean install of WinXP then the drivers from Zen's post, and Nicky's Win7 laptop. I also tried several versions of Linux. Only Mint's Gparted could see it as /sdb/ with a corrupted partition. I even gave Haiku's Drive Probe a shot. Jack of Clubs, I tried the SDK shell but it just scans and sees nothing. I just think that the USB thing is roadblocking any hope of saving this heap. Recovery is there, download mode is there, but the connection required to utilize either of those is gone.
Again, I truly appreciate the help.
Well I've been trying to get CWM to see the Infuse Toolkit (and various roms) on external_sd but it keeps saying:
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(Invalid argument)
E:Can't mount /sdcard
I've tried 4 different microSD's formatted as FAT, FAT32, and I used SDFormatter (I saw someone recommend that somewhere). I really see this as the very last ember of hope for this phone before I let it go.
Any ideas?
BTW, my CWM is v2.5.1.3 - Voodoo lagfix
Thanks again and in advance.
Infuse GB recovery menu will not see external SD card.
If you can get adb working - connection to your PC - you have some options. From adb there are commands that will allow copying files from PC to phone ... also from external to internal sd card depending on which kernel you are running. You could also rename your hidden folder too.

Thanks again for your continued help Zen. I just can't get it recognized (in a constructive way) by anything. I tried Santoku linux today and nothing. I've just been beating my head with this thing. Well here it is: CWM is accessible, as is download mode, and it charges fine, but no PC connection. When it was given to me, the glass was cracked, but it always worked fine for me. It's in a Ballistic case. If your interested in it, I'll be happy to send it to you, even if it's just for parts. I loved this phone, and had a lot of fun with it. (thanks to this community and all of its' contributors) I think it's time to move on.
I'm gonna start looking at a phone with a good selection of custom roms cuz I just love flashin' 'em
Let me know if your interested in this phone Zen.

[Q] USB OTG on CM12

I am using Oneplus one smartphone and flashed CM12 a couple of days ago. I cant use the USB OTG option properly. Updated to 31st Jan build and still go the issue. I am rooted and hence used a couple of softwares like Stickmount, USB OTG Helper and all and none of them solved my issue.
The exact problem is like this.
1. Can mount a USB but wont show in setting->Storage
2. Can access with a file manager.
3. Wont thus be able to unmount as there is no option at all like there was in 4.4.4 kitkat.
4. Even if you unplug it will give a message saying usb was not removed properly kinda.
5. After an instance this wont detect any usb and to do that you have to restart the phone.
HELP PLEASE!!!

USB otg helper has an unmount option, so once you're finished just open that app and hit unmount. The fact that it doesn't show up properly in Settings/Storage shouldn't really matter as long as you can access it with a file manager.

But USB otg helper keeps on crashing for both mounting and unmounting. Without a proper unmount the device won't recognise another instance in this case.

USB Connection Issues

I just rooted my s8+ with partcyborg's samfail and everything is working great except the usb isn't being recognized. I can see my phone on my computer and I can move files to my desktop but on my phone I get this message - "The connected device is unable to access data on this device. Reconnect the USB cable and try again." I have USB debugging enabled in settings. I'm using windows 10. ADB is up to date. I installed the samsung USB drivers. The device isn't recognized in kies or smart switch.
I'm at a total loss here. Any ideas? Could this be related to the 80% battery bug I was seeing? It's been at 80% for a while now.
Apologies if this is an obvious fix. I haven't rooted a phone since kitkat I looked around but the other threads weren't helpful.

So what do you wanna do with your USB connection? Just MTP (e.g. transfer files like you would when connecting a USB-Stick to PC) or you wanna do some ADB operations?
If you just want to transfer files, there's no need to have USB-Debugging enabled (in fact this is kind of a security risk when you connect to an unknown pc)

I'm trying to use the phone as a bootable drive because my USB stick was stolen. I want to put a linux distro on my laptop.

Yeah I've been trying to use drivedroid but it says there are issues with the mass storage. I'm going to send the dev a message with the ROM and see if there's anything he can do. For now just gonna flash back to stock
