[MOD REQUEST] Enable UMS to Galaxy Nexus

Is there any Kernel Developer who can make this true?
Its so hard to enable The USB Mass Storage for Nexus (like Xoom?)
Please take a look on this because i thing a lot of people here will love this!!!

please search. This has been requested about 9 jizzillion times.
That's right.

and whats the result of all this request?

I haven't looked around much but being that I haven't heard of any ums mod...I'd say mostly nothing.

It's not possible without repartitioning the phone and afaik no-one's tried it.
The reasons why have been explained multiple times, try a search.

If you're running Linux you don't have to.

and how's that?

The premise is that mass storage mode isn't possible because the SD card is not FAT32 but ext4, as such if the phone supported mass storage mode you wouldn't need to repartition under Linux since Linux natively supports ext4.
That said, why bother with something as quaint as cables when Linux also supports SSHFS and your phone supports an SSH server?

i would say because of speed, and not having wifi everywhere you want to connect your phone.
is there already a way to export a block device/file to the usb port as mass storage?

I use Windows and MTP works fine for me. I wouldn't need UMS.

Internal Storage/"SD card" format type?

What format is the phones internal memory and "sd card"? As in NTFS, FAT32, ext3/ext4, etc...
Trying to mount my Gnex to my Nexus 7 to access its SD card and it's not showing up with the stickmount app, which I believe can only read NTFS and FAT32.
Both devices are rooted, and the N7 reads my 64gb NTFS thumb drive just fine.

The Gnex mounts /data (including /data/media/) as ext4 but the only protocol available for data transfer over USB is MTP (media transfer protocol) there is no support for UMS on the Gnex. MTP does not support the functions you get from a usb storage device or portable media like SD/MMC/etc.
TL: DR; You can't mount it like a drive, by design, and if you could, you'd need to mount it with linux.

Two people on the N7 forum have successfully mounted their other devices to the N7 but I don't know if those devices use MTP or not.

Similar to what tekk mentioned, the GNex does not support USB mass storage mode, while those devices obviously do.

Can i write to Usb stick using otg?

Hi,
I am using stickmount to read off my USB stick, I was wanting to free up some space on my nexus and copy some files and videos across but I always get a failed message, my stick is formatted to NTFS to fit my HD movies on.
Is it possible to write to my stick or will I have to do it through my PC?
Cheers.

Sent from my Nexus 7 using XDA Premium HD app

I'm not sure if stick mount is able to write to NTFS partitions, or is only able to read it.
I'm pretty sure it'll work if your USB stick is formatted to FAT32.

Thanks for the replies.
I will buy another USB stick and format to fat32, I need this one formatted to NTFS to fit my HD movies over 4gb.
Cheers.

From Stickmount's description in the Play Store:
----- Filesystem support -----
The filesystems supported depends on your device firmware. On most devices, at least vfat/fat/fat32 and ext2/3/4 are supported. On the latest Android versions, ntfs is also supported in read-only mode. Some devices also support exfat out the box, but most do not.
StickMount can utilize the "ntfs-3g" and "mount.exfat-fuse" binaries to add support for ntfs (untested) and exfat, but these are not included. If you place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard ), StickMount will automatically use them.
You can find the needed files here:

Stick mount didn't work at all for many of my USB drives. USB otg helper works much better IMO, but the features are not as nice.

PJ's suggestion did it for me.

Any way to get around the 4GB size limitation of FAT32 file system on Pixel for OTG?

I can't figure out how to get around the 4GB file size restriction on the Pixel 3. I never had any problems using an exFAT file system on external hard drives/USB drives on previous phones.
It seems that if I attempt to use exFAT or NTFS file systems on my drives, the Pixel will not recognize it, format it back to FAT32, and I'm back at square one.
I've tried to wirelessly transfer files from PC to phone through Portal, using the external drive as the storage device, but that didn't work either.

??? I have a 128 gb USB c thumb drive formatted fat32. It's working fine on my pixel 3.

I can get FAT32 to work. But FAT32 limits file sizes to less than 4GB. I'm trying to have larger movie files on a USB drive to watch on a long trip. Can't put them on a FAT32 formatted drive because they're way too large. And Pixel doesn't support exFAT or NTFS.
I'm trying to find a way around this, unless I really just have to resort to splitting all of the files into smaller segments. Was hoping not to have to do that though.

Windows artificially limits fat32 to 32 gb so if that's all you need it should format it fine. If you need more there are 3rd party apps or you can do it in a windows power shell running as administrator. In a power shell use format /FS:FAT32 X:. Where X: is the drive letter of the device you're formatting.
Edit, you know what. I miss understood your question. I was thinking partition size not file size. Sorry about that.

Yeah, realized I said small when I meant the file sizes are too large. Either way, I'm hoping to find a way to get my pixel to be able to "see" some 8GB or larger files on an external storage device. I've used a couple apps that said they allow read/write NTFS and exFAT file systems, but none have really worked.

I'm just passing through, I don't own a pixel. But normally you need a kernel that supports either ntfs or exfat or both. I saw there are 2 kernels in the development section. Have you tried those?

It is not an "artificial" limit. This is how FAT32 was designed to work.

Those apps never work without root. Even with root, they're still finicky.

As stated here, a custom kernel with exFAT support is your best option.

I agree to a point. It was designed to work that way since Microsoft is pushing NTFS for larger partitions. You can certainly have FAT32 partitions larger than 32 gb.

Let's be careful here because you're confusing file size with partition size. Microsoft is not "pushing" one filesystem over another. The FAT32 filesystem had too many limits for servers which is why Microsoft introduced NTFS. As consumer needs grew, NTFS was made the default for Windows filesystem. The same applies to removable flash storage. To get consumers and manufacturers away from FAT32, Microsoft created exFAT. Microsoft, Apple, and Google are all competitors and they all have default supported filesystems. Microsoft and Apple user proprietary filesystems while Google sticks with open source since it's patent free. Which is why Pixel phones do not support Microsoft and Apple filesystems by default.

There are a couple of apps that allow accessing exFAT and NTFS file systems via OTG. Here's one I've used:
https://mixplorer.en.uptodown.com/android
It also allows accessing the files directly, so a slow copy to the phone isn't required for say playing a movie.

Question Connecting SSD drive

I have a SSD I format it in NTFS and plug it into the phone, it tells me that there is an issue with the drive.
So I format it with phone. Then plug it back into PC and it says it formatted it to Fat32, this makes it impossible to move any video to it.
My main idea was to use it for backup of pictures and video.

You done it in a wrong way. Sadly, Android devices don’t support NTFS format by default, you have to do it manually. Depends on whether your phone is rooted or not, it has different ways. Without root, use Total Commander to do it, with root, you get more choices. I didn't do it for a long time so can't tell just by memory. You can Google it and there should have a lot information you can get from the web for how to enable NTFS format in Android.

I am rooted, but have not seen a way to do it. Most say Total Commander or Paragon. Searched around web. Some of the threads are super old. And having issues finding ways to do it with Rooted device.
There is no Magisk modules anymore. Will keep looking.

That doesn't work.
From what I read , it seems Pixel 6 Pro does not support those formats. and you have to do work arounds to get it done.
Still working on those

Correct, Pixels never support ExFAT natively. There "may" be others way to use it on Pixels now, but I'm satisfied now that after all these years of having Pixel phones I bought the full Paragon deal: exFAT/NTFS for USB by Paragon Software. It's not ideal, but it works, and paying for the full deal gets me both ExFAT and NTFS (among other things that I probably don't care about).
I still use X-Plore File Manager to access the external storage through Paragon's app.

exFAT is natively supported on Android 13, at least for Pixel devices. I have a USB NVME drive that's formatted as exFAT and my Pixel 6 Pro running the latest Android 13 beta recognises it natively with full read/write access.

Did that program and it mounted it, but accessing is an issue. Not sure if I am doing it right,
For some reason it keeps asking to use total commander

I know it suggests Total Commander, but there's an option somewhere in there where I could get Paragon's access listed in X-Plore File Manager, which I prefer.
It's possible I didn't have to do anything special in the Paragon app - it's not too often I have to use it. It might have been just using X-Plore File Manager's ability to customize what mounted "drives" it listed, and adding Paragon from the list of available drives - after I already mounted the actual drive through the Paragon app.

I've partitioned my external SSD to 3, and only 1 is exFAT. The rest are NTFS.
In stock android 13 it is only able to read the exFAT partition.
To my surprise I noticed that in AncientOS (12L), it can read all in file manager. Don't know why though! didn't bother to read the features.

use exFAT supposed now with android 13 .
