is usb mass storage possible with root?

Just got a brand new Galaxy nexus today and haven't got a chance to root it yet. But i was seriously appalled by the fact that it doesn't support usb mass storage, which i did not know before buying it.
I just wanted to know, will rooting make usb mass storage possible?
no sd card and now this? I mean i love the phone but i can only take so much.

So you bought a Galaxy Nexus, but didn't know it didn't support UMS?
What's your specific problem with MTP?

MTP?
Yes i did buy it without knowledge of that. I guess that's what i deserve for not reading fine print?
You failed to answer my question though...
Rooting must enable mass storage though or how would roms be flashable?

ROMs are transferred to the phone via MTP on Windows, just like music and videos are transferred.
MTP is the replacement for USB Mass Storage. You can still transfer files back and forth.

Thank you. I came from an incredible and i guess i expected everything to be the same.
My bad for posting prematurely and now i probably look pretty stupid, but i can blame it on it being late. thanks for your help anyway.
Looks like a got it figured out. Thanks again.

your question still wasnt answered. and yes some roms offer it i believe

MTP does not transfer everything.
Try transferring your titanium backup files from your Nexus to your PC via MTP. I dare you. They're NOT there when you look at the Nexus from the PC-end.
Extracting stuff via "adb push" works fine though. This, and not having a drive-letter (so that things cant be scripted) was one motivation for me to start working on this thing:
http://forum.xda-developers.com/showthread.php?t=1423392

Google/Samsung switched to MTP because now the OS and the files are on the same partition. So if you would mount the whole partition as mass storage your android would get down :-D
Maybe it could work with creating a new partition?

please please please work on this!!
I NEED UMS support bad!

Just transferred my contents backed up by TiBu. Works fine.
You are right, they are not viewable from PC to phone. They transfer and copy fine (entire directory).

tried this many times. titanium transferring works perfectly.

Well, my problem is I work on pc's , sometimes a customer's machine doesn't get the Ethernet or wireless drivers after and install. I would normally download them on my droid x and use mass storage to transfer the file over....that works in windows 7...NOTin xp.

it's called a flash drive, have you heard of those?

I'm sure the OP has heard of a flash drive. However it would be much easier to just mount the phone like he has done in the past to transfer the downloaded file. Fishing out a USB OTG adapter, flash drive, and transferring is just extra steps.
Yes, a flash drive is probably the best bet for now... but I see why the OP finds it less than ideal compared to what he was used to.
Perhaps someone will come out with a custom ROM that has a new partition scheme to allow UMS. I personally wouldn't mind having a little 512MB partition on here for just that purpose.

No no no. Keep the files on the flash drive. Plug it into the computer. Win? Or if you need to find new drivers, you surely have a laptop you can use at work. Faster to find + download then using the phone anyway.
Having your phone + USB cable to hook it up to the computer is more cumbersome than just keeping the drivers for your work on flash drive

What if you need to transfer different files back and forth, and don't always keep a flash drive on you? I found with my HTC Desire that having mass storage was very useful for when I didn't have a flash drive... Admittedly, I can use my gnex for the same thing as all computers I use have win7 - but that is beside the point!

Surely it is possible to create some app, so as far as the PC is concerned it is connected to a USB device, but on the phone something else is occurring? Through some buffer or something...
I'm interested as well, as I'm having some trouble setting my Fedora laptop to talk as MTP. I'm comfortable transferring files via ADB but it can be a chore, and obviously none of my friends will have adb on their computers so transferring files socially will be a little hampered...

It should automatically prompt you to view internal and external sd cards on your pc. Are you rooted?

i have this problem on XP sometimes too, even with the drivers installed.
Try changing it from MTP to PTP. Let the computer find it again, then switch it back to MTP. Works for me every time

and to answer your question, i am not rooted. DO I HAVE TO BE ROOTED TO VIEW FILES ON THE SD CARD ON MY PC VIA USB? please help because i'm on the verge on stomping on this galaxy s3. thanks,

i seriously dont want to use airdroid.. i need to move heavy files and i dont want to spend years by my PC waiting for my phone to finish transferring files over the air.. i want to be able to see my sd card via usb.
thanks for the encouragement.. i know i'll get a solution with your help..

Fair enough. What if you do install windows media player 11 and see what that does?
Sent from my SGH-T999

Um the sdcard can only write at about say max 80Mbps sustained. WLAN will be fast enough at 40.. what is USB2.0?
Anyways if you are putting lots of files, leave them on external, and don't have to worry about copying again. No good reason to have then on sdcard vs external.
You can just copy to ext then use any file mgr program to copy it using the phone.
Sent from my SGH-T999 using xda app-developers app

I use N so it's 100mbps and fast enough to not notice any difference. I'm guessing your problem is that XP is old as F. A simple solution is to just plug the sd card into your computer. But as it was pointed out the sd card is slower than wifi so it really doesn't matter.
Oh and I'd just like to point out you could have moved the files 10000 times by now. With airdroid you can move around the house while files are transferring. So you can relax and still use the phone instead of being tethered to the computer. And if you have splashtop you'd never even have to touch your PC.

Put Linux on a flash drive and use that?

[Q] Is there a PC app to root browse SGH-M919 on PC?

After trying multiple search terms, I can't seem to find what I want.
Is there a PC app that would allow me to view the entire root file structure on a PC and maybe transfer files to a folder on the PC? In other words, copy the entire internal SD to a folder on PC.
This is for my old S4 that has a broken screen and I can still see this device on my Win 7 pro PC, but I am looking for something that works like root explorer does on the device, but for the PC.

re: window explorer type app to control the phone.

Here is just the thing for you, it's called "Android Commander" and it does everything,
looks like a windows explorer, installs in windows, it installs apps, flashes zip files,
does adb automatically and you do not need to type anything in a terminal window,
drag & drops just like windows, cleans cache, sets permissions, mount/unmount and
just about anything else you can think of.
With this app there's hardly a reason why you would have to do anything in recovery mode.
It also has built-in boot to recovery, download mode, power off phone and reboot.
It's fully compatible with all models android phones and it's really easy to use, self-explanitory.
It can connect using USB or via WiFi. (usb is best)
Check it out, here is the direct download link for it:
https://docs.google.com/uc?id=0B44Nx1hrRITWOVczc0FzZEt6OFk&export=download
Good luck!

Wifi File Explorer is a good one, too.

YES! Thank you very much! Exactly what I was after! Wish I could hit that "Thanks" button more than once.
EDIT: I will keep trying but commander is not listing the phone. Not sure if I had busybox installed on the device.
EDIT 2: Didn't have much time yesterday but I still cannot get this program to recognize the phone with broken LCD, nor my new one but both show up in Win 7 professional just fine. This is more curiosity now as I ordered the OEM Samsung M919 T-Mobile Galaxy S4 LCD Screen Digitizer Touch Panel Frame. Wasn't cheap at $194 USD but I can fix the old device in under 30 minutes when it arrives.

Auto-cancel when copying files to PC

Hi guys, I'm just new here. I have a problem with my Zenfone 2
I'm trying to backup the files of my data manually to my PC but after like a minute of transferring files, it auto-cancels. Is this a problem with the Zenfone 2 or the PC?
Debugging mode is turned on and I even tried using Share Link but it still auto-cancels when it copies some files. I need to backup because I plan on installing CM 12.1

Make sure it never gets moved while copying, maybe also try another cable or USB port.

check your cable or the connector, it seem to be the intermittent connection you are having.
nothing about the software.
mine happen to cancel too, when i use one of the usb port of my pc.

I had this problem with Moto E. Some files simply doesnt copy (i dont know why). I solve that with a simple solution: SD card!
Copy to sdcard, then put in a card reader, copy to pc. profit.

Your usb stick is not a computer, it does not need to read your phone with MTP protocol.
The phone should provide power to the USB stick, exactly as it is saying, so that your phone can read the contents of the USB stick.
Get a File Manager like FX to transfer items to and from your USB stick.

I have the same problem. It always says usb charging and I could not transfer pictures to my usb using the usb-c/usb adaptor. I tried using file manager app but I get confused with all these asking permissions and I end up unable to transfer anything. I never had this problem with my S7 edge before. I tried connecting the phone directly to the mac using android file transfer but could not connect. I would really appreciate if someone can give us a more detailed steps on how.

I tried that I have ES file explorer like "edsol" said it won't mount the stick because it's in charging mode
I tried several time to switch it off of charging mode but always flips back after a few seconds.
if "edsol" has the same problem then I guess it's not just my phone........there must be a fix for this??

I had the same situation, and I had to format the USB stick in "exFAT" to be able to copy files to it. NTFS is supported only for reading, but not for writing.
So check that your USB stick is not NTFS.
FAT32 and exFAT are the same, the difference is that exFAT doesn't have the FAT32 limitations (maximum file size of 4 GB)

Thanks...but it is exFat......I did a reformat just incase.......still a no go ??

you probably need some file manager to do what you want, Android sucks when it comes to manual file management.
Anyway I have ES file explorer loaded on my phone, so plugged in USB c to USB2 adapter, put in 32 GB FAT32 memory stick, ES file exp. open up and I transferred couple files from stick to SD, just to test it if it works. It did, but you would have to pay me a lot of money to do it on regular basis, so awkward. I just plug my phone to PC and use windows click and drag to move files around. Now I run into problem, when I was transferring my pictures, couple days ago, F???? Android lock my sd card for no reason (F????? Google is messing SD cards on phones since at least kitkat). I had to fix sd and take write protect off, but I'm sure it's Google not Samsung. Anyway, it works like a charm, just watch out for Google's broken permissions showing it's ugly head.

What File Explorer are you using? Some of them can't write to external storage because of Marshmallow permissions.
"My Files" of Samsung worked for me while "ES File Explorer" didn't work (before root)

I used ES File Explorer, I'm sorry I said wrong in my previous post, I moved couple files to phones DCIM folder, not SD, it's so awkward and I just wanted to see if it works at all, it did, I confirmed the files were moved, before deleting them. So actually I don't know if it would work on SD card, but I would never ever transfer files like that: I would use my pc laptop for direct transfer between SD and stick. So the concept I described works, but as far as permissions to particular folders go, they're so messed up and don't even want to test it again against SD. In theory it should work at least for transfer to root directory, since card is not protected, may not work for transfer to folders created by other programs due to permissions. At some point I may have to root this phone just to fix those stupid permissions, but I haven't used Marshmallow until now, so not sure how broken those permissions are here.
