[APP IDEA] Mount disk image as USB mass storage

Hi, this is my first post here. I've been meaning to sign up for a while, but just had an idea for an app that I can't make and decided I had to spam it somewhere in case it inspires someone. Anyway, here it is:
If it was somehow possible to mount a disk image instead of the actual SD card, it might be possible to have a bunch of handy boot images for fixing and administering computers.
For example SystemRescueCD, Ubuntu's mini install CD and a Windows password recovery disk would fit into about 150MB, which is tiny compared to a 16GB SD card.
Would this be possible? I guess it would require root if it was, but it would turn your Android device into an administrator's swiss army knife.

Sounds like a cool idea if possible...

I was actually exploring this a little bit.
First issue is you can't mount an iso (ISO9660/CDFS) under Android, however, you could an ext3 image. I didn't get much further than this when looking into mounting images.
Second issue is, I have no idea how to tell Android to mount /this/path/to/usb/mass/sotrage rather than /sdcard.
I will be messing with this some where when I can. I think I'd tackle the second issue before the rest of the first one since I'm sure a fat32 (for Windows) or a ext2 image could be mounted and booted from in general.
I'll post any updates if I find anything out.

I've made quite a bit of progress on this idea. I have successfully mounted a usb drive image and been able to share that via USB Mass Storage. My problem now is, I can't seem to get my Captivate to be seen as a bootable USB drive on a PC that is booting.

I would be interested in knowing how you did this, if you'd care to share it

I would like to know how you did that too

I have been wondering/playing around with that same idea.
I also looked for the /system/ect/cdrom.iso file that all these posts seem to mention as well and have been unable to locate it.
There are three ideas that I would like to put out there...
1.) Replace the Virtual "Motorola Driver" CD that auto loads when "USB Mass Storage" is on and "USB debugging" is off.
If you enter the boot menu on a computer with those options. When you go under CD-ROMs to boot from, you will see "USB-CDROM0: MotorolaMB810 000" as an option. This depends on your phone of course.

2.) Put an ISO on the internal memory and have the OS auto mount it as per an app or some start up script. (Would be nice to have a widget that when on mounts an bootable ISO for us techs)
3.) Create a 2nd partition on the SD card that computers recognize as a boot drive. (Prob the most limiting of the three and not the one I'd like to see be done compared to the others.

Has anyone looked at this? Can't seem to get to work on my GS3 though...

[SOLVED]Help with ADB, I've tried everything I can think of.

Guys I'm at my wits end. I'm about to give up. I'm trying to get adb working on the nook here on my work computer. I can't for the life of me get it to work. I had no problem on my laptop, but then again I think I caught it before windows installed anything.
I've been using "usbdeview" to uninstall rogue drivers, trying to reel in the problem. However every time I go into device manager, it try's to install "Android ADB interface" which I think means its assigning the wrong driver to it. It should be "Android Composite ADB Interface", no? I know thats what it is on my laptop.
Anybody have any last ditch efforts? I should note that adb works perfectly fine on my Aria on this same machine. I love ADB, hate the setup though.
*****EDIT: Working on different usb port*********

You aren't alone, m8.
I used to have no problem with ADB over USB. But after re-formatting my laptop, I just couldn't get it to work, no matter what I did. I gave up
I'd tried wireless ADB, everybody said it's so easy, me? Couldn't ever get it to work. Gave it also.
At least, for now, I wouldn't think I need it.

I'm now convinced its not driver related. There is something holding my computer back from talking to it. But I'm 99% the right drivers are installed. Mounting disks works fine and it identifies like my android phone does, ADB just won't talk to it.

Try unchecking and rechecking Debugging mode...

Tried that many times. Just for fun I ran the easy adb executable on another machine here, THEN plugged in my nook to it. ADB worked perfect. I'm frustrated, but I really want to figure this thing out. (btw, it identifies with the exact same drivers on both machines)
EDIT: Don't know why or how, but for some reason switching usb ports (which I swear I've done before) worked!!!!!!! It now recognizes and can push/pull/install over adb (usb).

WWW.Ubuntu.com
Enough said.

Love me some Ubuntu, but CMD prompt > Terminal every time.

If you don't mind, can you provide the link to where you downloaded the driver?
Thanks

I used the "combo" pack which installed the drivers and a stripped version of ADB to C: (redundant since I already had ADB installed).

Thanks audio,
I'll give it another try.

DISCONNECT YOUR COMPUTER FROM ANY NETWORK TO AVOID WINDOWS UPDATE GOING ONLINE AND INSTALLING INCORRECT DRIVERS
Make sure you're Nook is identifying like this when its plugged in via device manager. If you're unsure how to get here; WINDOWS KEY + R, type without quotes "devmgmt.msc", hit ENTER.

I got all those except the Disk drive list above.
I'll give a try and see what happens.

We may need to uninstall some old drivers before we can get it to install the right ones. You on gtalk or msn? I'll help you troubleshoot it the best I can.

Works like charm.
LOL , without this thread, I would (actually I did) abandon installing ADB over USB.
Thanks audio for providing the correct link.
Gotta love this forum.

PC don't recognize Galaxy device - please help

Hello,
I own a Galaxy s4 i9505G android 4.3 stock, normal, no changes and nothing special.
My problem is that whenever I try to connect it to a computer (running Win 7) via USB cable - it won't get recognized and nothing will happen...
It will however charge the device - so the problem is not in the cable or something...
I looked up soo many guides on how to fix this problem, most of them told me to try and reinstalling the samsung drivers manually - no success I even tried uninstalling existing drivers (as suggested somewhere...) - still, nothing happens... - tried to connect it to a different pc- same problem...
Any1 has any ideas? - I'm really desperate and its REALLY annoying that I can't do ANYTHING that has to do with connecting my phone to my computer...
Please help, Thanks in advanced.
EDIT - FIXED
check my other post down below to see what worked for me! GL!

have you figured out what is the problem?
happened to me today and still searching for answer.
i try different cable, different computer, connect it and nothing happen, my s4 9500 only charging.
but screen mirroring to tv using mhl still working.
im afraid if the micro usb socket inside the phone is damaged.
if that is the problem im screwed because my bootloader isnt official anymore and i wonder if i still can claim for warranty.

Did you try to uninstall/install the usb driver?

just now what i did
1. go to storage > unmount sd card
2. turn off phone, pull out external sd card
3. turn on phone, unlock screen, connect to pc
4. now my pc recognise my s4 and installing driver (weird my driver is already installed, i never uninstall it)
5. turn off phone, put back external sd.
6. now problem solved.
(you can try unmount, then mount again, connect to pc see if that works without pulling out sd card and shutting off your phone)
thank god its not the micro usb port.
now i can sleep peacefully.

Finally found a solution for me!
HEY EVERY1! I know it's kind of bumping this thread but I wanted to share with you what worked for me!
If you are having the same problem: when you plug the phone to your PC it charges but nothing happens - check to see if you have the MTP even showing up! - thats what happend to me - it wasn't a driver problem - it was that the mtp service just didn't start when I connected it to the pc.
the solution to this (what worked for me)is:
1. Open up the dialer
2. type in: *#0808#
3. a screen will pop up with a list:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4. now for me, the MTP option wasn't enabled for some reason (nothing was enabled except the USB part)
5. just tap on the MTP option and press OK and it should appear when you connect the phone to the computer and install the drivers automatically if you don't have them already
~DISCLAIMER!~
I'm NO expert - I barely have knowledge about the android OS - I simply learned a little bit and have a brain to read and connect the dots - I just want to share what I found out through digging up knowledge around...
This worked for me on a google edition galaxy s4 - stock android 4.3 - no changes to ANYTHING whatsoever...
This is just my second post here - I really like this forum and I'm starting to learn a lot
Hope it helped! Good luck everyone!

Nexus 6P USB access

Hi guys, on my previous phone (Xperia Z2) I can plug in to my computer via USB and copy files to/from the internal storage or SD card. When I plug my Nexus 6P in to the computer the same way, I just get an empty folder. I can't see all the files on the internal Android filesystem. Is this normal?
(I'm trying to copy some files into the /Android/data folder)

I've always been able to fix this by going to Developer Options (assuming you've set yourself up) under Settings, selecting "Select USB Configuration" and then toggling from MTP to PTP and then back to MTP.

I tried that and I can see and copy over pictures but i still cannot copy music and other files. When I go back to MTP the option to see the phone goes away.

Are you sure you enabled file transfer as an option from the pull down menu?

I did enable file transfer. When I do I get the bing, bing, bing, sound in lowering tone, not in increasing tone. i.e. I get the sound when disconnecting a device. When I enable PTP I can access the DCIM and Pictures folder, but that is it. When I go back to MTP, i just get the disconnecting sound and my access I did have with PTP disappears. Any suggestions?

Lol - that can be fun.
Seems, for Windows anyway, the trick is getting the right driver to install, instead of what Windows likes to auto install.
That usually means uninstalling drivers, better yet, manually installing/updating the driver with the proper one.
You can Google the issue for more detailed info, way too much to go through here.
Good luck!

View files on PC using adoptable storage

I know that adoptable storage is encrypted, but is there any way to easily transfer the contents from my phone to my PC now? I just want to take pictures off and move them onto a network drive. I have TWRP 3.0.0.0, MM (without the Feb security update, since that still won't install), and an unlocked bootloader. I am NOT rooted, but am willing to do so if that will solve this issue.

Haven't heard of anyone successfully doing this as of yet. Perhaps a future Android update will fix this or a solution will arrive via a xposed module. The best workaround currently is to backup photos to Google drive (or some other service like OneDrive) and retrieve that way.
Sent from my awesome phone!

I have access to my files on PC.

Is your SD card set as portable storage or as Adoptable storage? I know that portable storage allows PC access (since it is not encrypted), but have been unable to access from my PC since converting to adoptable.

Adopted of course. You allow access and it still doesn't show on PC?

Well, what do you mean by 'allow access'? Are you talking about one of the options from the USB debugging notification in Android, or something different?

Whoa- I definitely have tried messing with those USB settings to no avail, but when I looked at your screenshot, I noticed that you had USB debugging turned off (mine was on).
When I turned it off, I could now see the SD card listed in Windows (progress!) but got a new error coming from Windows:
"The device is currently busy and its contents many not be fully displayed. If another application is copying data to or from the device, please wait for it to finish and then retry."
When i click 'Ok', it returns me to the Windows Explorer screen showing my SD Card as empty. When i re-clicked on the SD Card in the Explorer nav bar, after a few tries i could see my files (i sometimes have to change the 'Use USB for' setting for some reason. Sometimes Transfer Photos seems to work, and sometimes Transfer Files. I'm not sure why the erratic behavior, because i can now at least get to my files as needed.
It seems that (at least for me), I need to turn off USB debugging to see my files. Has this always been the case? I can't remember needing to disable it in the past- maybe it behaves differently now.
Either way, many, many thanks!

No it works fine with debugging turned on as well. I suspect a driver issue with Windows. Or, a faulty cable.
