[WIP] UMS/MSC storage

First off: UMS/MSC is USB Mass Storage/Mass Storage Class
This is something I've been working on. We don't have UMS. And, I want UMS. Google/Samsung's reasoning was they didn't want to make us choose between internal storage for apps, and external storage for music.
The one flaw that comes with this is that we lose UMS. UMS requires a block device that can be unmounted from the phone and mounted to the host machine (Windows/Linux/Mac).
We can get this back relatively easy I believe without re partitioning our phones. I don't want to play with partition tables, because there isn't an easy way that I know of to restore it to stock.
To get technical: /sdcard on the Nexus is just a symlink to /data/media. We can break that symlink, modify the fstab and init.rc to mount an image file to /sdcard, then modify vold to allow us to mount that image file to windows. The downside: we'd lose what google/samsung thought was an amazing idea: not making us choose between sdcard storage and internal app storage.
I guess why I'm posting this: is anyone interested enough for me to actually do this?

What exactly is the benefit? Could you explain?

Sounds like a ext but to the sdcard instead of the data partition..

sounds interesting! the convenience of having UMS is definitely missed. as long as everything functioned "normally" I'd do it.

Yes please! Especially if u can do it so that it'll also work in clockwork, might be easier. It would make everyone's life easier, and I bet a lot of devs would end up baking it in to their roms!

If I am reading this correctly this would essentially make that folder act like it would under an external SD card meaning once I mounted it to windows I would lose all access until unmounting it from windows?

More options are always good, but honestly I've gotten used to MTP and not having to mount and remount as well as not having to worry about swapping between internal storage and sdcard. I say do it just so we have options as users, but I'm not really sure I'd use it over the current methods.

You got it. You could even use the folder as /sdcard and programs wouldn't know the difference.

This would be very very nice for Linux users as mtp can be a pain to transfer files with. And adb isn't exactly the fastest for large files.

Great idea. Mtp sucks

Would love this to use with my MacBook Pro.

Yes pleaseeeeee!!!!!!!

You should work for Google. I think that's how they should've shipped the phone.

Great idea. That would make device recognition much easier in Linux. It's a real pain trying to get it to pick up GN on Debian. If you get it working maybe I can have your permission to use it in my git for my rom compilation?

Be nice, current method with Macs is painful.

Transfer Files To and From a Mac

Hi I am using a Macbook and I plugged the Nexus selecting MTP option. I am unable to transfer data like songs amd downloaded from my phone to the Macbook. Is there something I should do? When switched to PTP iPhoto was launched and was able to transfer images only. Thanks for the help!

You need to download Android File Transfer.

Here is exactly what you need! all you need to do is download it, plug your phone in, and run it!

Note that it may not read the phone if the lock screen is up. Can be a pain if you're in a rush.

Yup. Random freezing, disconnecting, etc. Also takes forever to open a folder.

has anyone found a way around using this horrible program

i like airdroid (find it on google play) it connects to the same wifi as your pc or you connect to the mobile hotspot and you open http://ipaddressofthephone:8888 and theres a website where you can push and pull files and other cool things.

Many file explorers have WiFi transfer capabilities to/from your PC.

USB Mass Storage??

So tomorrow my phone arrives! Yay! I read some things about how the nexus doesn't support mass storage. Is this true? Sorry if this topic has been made a thousand times already but I'm on my phone so I can't do a forms search.
Sent from my Incredible 2 using xda premium

It is my understanding that the GNex uses MTP which is another transfer protocol.
Essentially, instead of having activate mass storage mode, like with UMS (USB Mass Storage Mode) your GNex will already be in "mass storage mode" and anything you load on the phone should automatically propogate to the phone in real time.
Hope that helps,
Dan

It does a little. So can I copy files from my Mac to my nexus or not? I am confused.
Sent from my Incredible 2 using xda premium

You should be able to transfer from any computer (including your Mac) to/ from your Gnex.
Essentially, it uses a different protocol to communicate, but to you it should work about the same.

The Galaxy nexus doesn't support USB mass storage.
Android File Transfer is what google suggests that you use.I find it to be a bit buggy on OSx, but it may be fine on other platforms.
Alt Mounter mounts your sdcard similar to what USB Mass storage did on other devices.
They both have their quirks. If you are familiar with using adb through a terminal, that might be the most reliable method.

Android File Transfer app works just fine on OSX. Connect the phone and drag/drop to or from. No mounting or ejecting. Just use it.
The GNex can't do UMS because there's no separate SDcard or partition. Its all one solid storage. Its a much better implementation.

I am very comfortable with adb and osx makes it easy. What commands do I use. I'm guessing something like "adb mtp (file name)"

Uhh. You can just use ./adb push and ./adb pull if you want, but just use the Android File Transfer app. It works just fine.

OK. Cool

[Q] sgs3 copying files from pc slowwwww

anyone has the same problem .. when I try to copy large files .. for example a ROM .. Search Google and the problem is with the new MTP protocol

I always download roms to my pc and use a card reader to transfer to my sd card. With that being said I have not had issues transferring directly to or from the phone when I have done so.

Yes MTP is horrible for mass file transfer, honestly I've completely merged to WiFi file explorer pro. 2 megabytes per second upload speed.

WiFi File Explorer PRO also supports internal memory???

No, its not MTP. I can transfer files pretty fast. Check which type of port your plugged into. It could also be your external SD card if its older.

[Q] how to transfer files to tablet

I am having trouble transferring files from the computer to my Nexus 7. Root and flashing ROM went fine everything else works flawless just can't load pictures or music onto the tablet. I am currently running android 4.3 and cleanROM 1.3 on new nexus 7. It must be something simple that I am overlooking sorry if this is a stupid question I did try to research it and came up with nothing. Any help would be greatly appreciated.

If you want to do it remotely (way more annoying than with a cable, but once you get use to it, it can get handy)
Transfer rates can be relatively speaking, slow, but doesn't become a huge issue unless you're moving a lot of large sized files (i.e., high quality movies, a library of music etc.)
I use SSHDroid with WinSCP (For windows).
If you run Linux you don't really need WinSCP.
Using this method requires a little know-how with SSH / SCP to get optimal use out of this method.
Also, as a side note, your files are transmitted relatively safely (i.e., it's encrypted).
