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...

How to Copy/Transfer files > 4GB to HOX

hi all
any1 know of a method or programs to copy/transfer files > 4GB to HOX?

Just mount as Removable Device, right click and Paste. I copied a 12gb HD movie to my HOX last night.

I have done that.. and then it stops to tell me cant copy/transfer files > 4GB because FAT32 does not allow it (Partition type limitation)
I even tried FTP'ing the file to the device and it stopped at 4GB exactly
Have you formatted your card differently?
are you using windows to transfer/copy the files? (I am)
do you use the standard windows copy/transfer method? (I am Using TerraCopy)

just plug the usb to pc and format the sd card as NTFS and you can remove the limitations of 4GB

Won't that affect how apps are installed as well? AFAIK most devs optimise their apps for FAT32, as it's the default format of the storage.

have you formatted you SD to NTFS?
as I have read on another Forum post that once they formatted the Card and rebooted.. the card reformatted to FAT32
@dr9722 could you please state all your system specs that has allowed you to transfer the files
including the model of your HOX and the ROM maybe this affects it as well (dont know why it should??)

personally, i split the files with this method:

website isn't loading at the moment, maybe server is down or something

if it still isn't working later theres loads of other pages that show ways to do it just search google for how to split mkv files
bit of a pain, but i normally watch tv episodes rather than movies so they're normally small enough even when in hd

It'd have to be formatted as exFAT or something. I don't know if it's doable, but that's the only way I can think of. Or possibly as ext4 and do file transfer via MTP.

Thanks man I know about that method but thanks for the info great help for those that wanna copy movies to their phone
my problem lies in an actual file Copy ie. DVD image
yes I can zip it and split the files into varying sizes but then it defeats the purpose as I would like to move the file as is (time saving)

if i'm honest, i don't think it's possible without a rom mod - maybe ask a rom developer if it's possible.
you would need to modify a lot of stuff so it all works together properly, and that's if its ntfs.
exfat would no doubt be easier on the android side to implement, but then you'd need an app on windows side to be able to read that (win7 might actually include exfat support actually...)
still it's not something possible by means of just an app etc i don't think.

dont think this is specific mkv splitting so you wouldn't be able to watch the split mkv, you'd need to go onto a pc and merge the files before you could watch it, which would then leave you with a file that is once again too big to fit onto the phone :silly:

[MOD][KERNEL] Stock 4.2.1 + OTG

Hi all,
For the purists amongst you, like myself, I have attached a modified, repacked boot image that will mount (automatically) external storage devices to /storage/usbdisk and /storage.
You need to be rooted and unlocked.
Installation:
Backup your boot image with recovery of your choice
Reboot into bootloader
fastboot flash boot neostock421.img
reboot into android
rename vold.txt to vold.fstab (XDA wouldn't let me upload a vold.fstab)
copy and paste vold.fstab (attached) into /system/etc/
set permissions on vold.fstab to 755
reboot
plug in your drive and enjoy
Notes:
The storage device will not show up in settings/storage, that requires modification of the framework, I could do it (if there is a suitable apktool available) and package the lot as an update.zip but for the time being I won't.
Observations:
I have observed that in Root explorer, the device is mounted read-only initially (you can simply remount read-write), but if I open /storage/usbdisk in Estrongs and return to Root Explorer, it's now read-write. Either way, you should no trouble getting read-write.
Warnings:
Do the above at your own risk, I take no responsibility, bla bla, etc etc.

Thanks for your stuff

It just auto mounts existing supported file systems, nothing more, nothing less.
I haven't tested it with anything other than a fat file system cause that's all I have on my pen drives.

What is your HD formatted in, FAT32 or NFTS?

How does this work with TWRP? Meaning, if a flash drive is selected as the destination, on a reboot of TWRP, is the setting retained?

Wanted: Asus VivoTab RT Recovery Files to download

My Asus VivoTab RT 64GB is playing up and I cannot refresh or reinstall the OS as I get an Insert Media missing files error (see photo). Obviously Windows RT tablets don't come with external media with the OS.
I would be eternally grateful if someone could copy the recovery files to a usb (an option given in the OS) and then upload the file to either skydrive, drop box or other host for me to download. Once downloaded, the file can be deleted from the host. I think the file is between 3.5gigs and 4gigs. I could then re host it for anyone else who needs it.
Please, I have contributed a lot to the xda forum and would really appreciate some help.
FYI I had sent my tab to Asus for repair and it came back with the ability to not be able to refresh pc and I am furious. I don't want to send it off again and be without it again for another two weeks.
Thank you!

Sorry, I don't have the tablet, otherwise I'd be glad to help.
I have the x86 Windows 8, and it has the option to create recovery media (I used USB). I gather this is how one would create the files you need? It is probably a stupid idea, but have you tried creating a recovery media (assuming you can get to those menus)? The recovery data should be somewhere on the disk, so it might work.

[Q] Copy file to External Drive -- size limit

When copying files by Samba or SFTP to my external USB drive there seems to be a size limit of around 2gb. Can the limit be increased?
Not a big deal -- I can always unmount the drive or segment the files but i'm curious.

Is the ssh mine? If so, I might have to look for a compile option for large file support. I know busybox has that option, not sure about ssh. Samba, unfortunately, is out of my hands.
Unless it's not large file support, but something else.

No it's this one: web.oss.sshsftpDaemon.apk
I think there might be a limit on the total amount of data sent at one time but I'm not sure.

It turns out that there is a --disable-large-files compile option for both samba and dropbear, but compiling without it didn't make any difference for me. There was still a 2gb file limit. Oddly enough adb push did a 4gb file w/o blinking.
