is it possible force the MTP mode into Mass Storage Device ?

is it possible force the MTP mode into Mass Storage Device ?
as for many users come from Nexus S , Nexus S uses mass storage device to communicate with PC for copy/past/delete files on internal SDcard
i found that it isn't same here on Galaxy Nexus , which uses new mode MTP ...
but i figured out this MTP is little bite pain in ass as i modified files with Root Explorer , but it doesn't show any changes when I try to access internal SDcard with PC to copy/delete files.
even i rebooted my phone twice or thrice , still doesn't show any changes ...
so i begin to miss the old MASS STORAGE DEVICE MODE as we had in Nexus S ...
is it possible to do so ?

If it was possible, it would have been done already. It is not possible on gnex because the sdcard is just a link on the /data partition, which cannot be unmounted while android is running.

There is no way to enable USB Mass Storage. You're gonna have to deal with MTP.

.... well, in that case any possible solutions to what I have described about no showing files change in PC ?

not possible in this configuration. And honestly why would you want to? I certainly do not miss the delay of mount/dismount, also being able to access the storage on my phone at the same time as the connected pc is so much more useful

I don't why and how to say it, for example, I want to mod SystemUI.apk so I copy from /system/app to /sdcard by using Root Explorer, then I connected my phone to PC, but windows explorer doesn't show SystenUI.apk exists in SDcard section while the Root Explorer indicates there is in the SDcard, even I rebooted my phone twice or thrice, it still doesn't show up in windows explorer...
This is what being bother me

i just attempted your exact scenario and windows explorer is now showing systemui.apk in root of /sdcard/, soon as i copied the file using es explorer on the phone i saw my windows explorer window flicker and updated with the newly copied apk. i did this while the phone was connected fyi

Try the app "sdrescan". It'll for android o re "read" the sdcard and populate any changes in it's database.

The implementation of MTP on Android 4.x is buggy. While it seems to work for some people, a large number of users experience issues with file transfers hanging & refresh issues. Forcing a rescan seems to work for the refresh issue.
Personally, I avoid MTP and use ADB for copying stuff. Follow the link in my signature for more info.

lol! try backing up your sdcard using MTP sometime.

This.

I know this thread is old, but hoping someone can help - I cannot find ANY undelete programs for Windows that recognize my GNex. They all require Mass Storage Mode or a disk drive, and even though "Internal Storage" shows up in My Computer, none of the programs see it as a viable location for scanning.
I need to undelete a lot of files from my internal storage (sdcard folder on my GNex). How can I mount this? Or how can I mount the entire internal storage as a "drive" in Windows? I'll put the phone in any mode I have to recover what I accidentally deleted. Can I do it from recovery (mount sdcard perhaps?)

bull****
look at the nexus S. it has built in storage and it used USB mass storage prior to ICS.
it is not a hardware limitation, it is strictly software. google did it so the partition can be EXT3/EXT4 and allow an unlimited amount of storage for apps
the problem with this is, even with its EXT3/4 capability, MTP is ****ing TRASH on linux. i can only send files to my phone, i cant move them onto my PC. i cant move/delete/copy files within the storage.. the only way for me to do it is through a file manager on my phone and even then it doesnt update when i connect to my PC until i reboot my phone a few times.
MTP is a decent technology but mass storage should still be offered. why not have a scalable partition for apps using EXT and allow the rest to be what it wants. i dont know. there are many different ways they could have implemented this internal storage thing but MTP is the worst way (at least for linux)

Nexus S's /sdcard is a separate partition, GNex's /sdcard is just a link to /data/media/0
In other words in with the nexus s the command umount /sdcard works and doesn't with the gnex.

again, not a hardware issue but a software issue.
why can we not partition the internal storage in this way?
the nexus S was partitioned to allow mass storage but with JB it doesnt allow it. it is obviously capable of reverting.
i dont know.. im gonna try to figure something out. ill come back with updates (if i remember to)

[Q] Problem connected my S4 via"Total Commander"

I always connected my phone to my pc via usb and use "Total Commander" file manager. To connect android phones I install "TotalAndDroid" plugin and all worke perfect. Now with my new s4 I can't see the internal and sd memory via "Total Commander". What do I need to define in my galaxy s4 to use "Total Commander" as always ?

If your previous phones used versions of Android less than 4.0 (ICS), what may have happened was that your phone now supports the Media Transfer Protocol (MTP) rather than USB Mass Storage (UMS). There was a tradeoff to the move. One big one regarding Android is that MTP allows the device to remain mounted on the phone. OTOH, your phone's memory is no longer visible as a drive (that was the catch--in order for phone memory to be mounted on your computer, it had to be UNmounted on the phone). You should check your system and see if it supports MTP (most Windows systems will as the underlying technique was Microsoft's idea).
In my personal experience (I run a Linux system at home) I've found it easier to avoid the matter altogether and transfer files back and forth using an Android file manager (I've personally used ES File Explorer for years) and perhaps a Windows/SMB share.
If you MUST use your phone's SD Card as Mass Storage, there is a thread here that discusses a way to switch the SD Card to Mass Storage mode. However, it will require rooting the device.

[Q] File transfer using usb cable

Sorry if this has already been discussed, but I didn't found any answers regarding my issue.
So how can I transfer files from my pc using the pad's USB cable?
On my Sony phone with ics, it was enough to enable usb debugging mode and the pc sees it as a flash drive, using usb mass storage.
But here it seems there's no mass storage mode, only mtp and ptp which I don't like.
So what options do I have to actually see my 64 gb card when I connect the pad to the pc? Is it possible?
Cause even with debugging mode enabled it doesn't change anything, still have to use windows explorer and it's working very hard. Any help would be much appreciated.

Not sure I fully understand what's wrong with mtp option but I can fully see my 64GB card when connected to my pc via usb cable. I have successfully copied files to and from the SD this way with no issue. Explain what issue you may be seeing.

Can not see why you have any problems when my G Pad is connected I can see it as a device in My Computer " Not Devices " and when I open it up I see two drives. Internal and external SD card
Make sure you have loaded the LG USB Drivers
Plus it should come up with a list of what you want to do when connected click Open and view files

Thank you for the replies, guys.
Not sure if i made myself clear. Yes, my pc can also see my g pad device in My Computer, but it is not listed as a removable flash drive or an external hdd, thus i cannot see sd card properties, format options and so on. I usually use total commander for transferring files, because windows explorer is way too slow in doing this.
For example, if i want to download a movie or some songs directly to my tablet, how can i do that? With my sony phone is easy, my pc sees it as a removable flash drive, thus is easy to save files directly to it.
But with the g pad that option is gone, or at least i cannot find it. I must first download the files to my pc and only after that transfer them to my pad using windows explorer, which is really working hard. Basically, i have to wait one hour for downloading something, than another hour to transfer the files to my tablet, instead of downloading directly to the tablet.
And all this i believe is the effect of usb mass storage mode missing.
So in the end, is there an option to satisfy my needs?

In settings, go to "system", choose "PC connection", choose "media sync(MTP)".

MTP option does exactly what i was saying earlier, it only gives me the option to use windows explorer to transfer files.
It does not satisfy my needs, as i cannot save files directly to the tablet's SD card when downloading something, for example.
Can you people see the tablet's SD card as another DISK drive in your pc? With formatting options, sd card properties and stuff that you can do with a flash drive or an external hdd? This is my question, but i believe this is not possible.

I have no problems it must be your USB drivers as mine sees it as a Device
I open mine up from my computer then open the SD card and transfer all my Movies and Pictures direct to the SD card I can open up files on Device or Card

Hi again, i've attached some print screens with the issue i'm trying to explain. The main thing that bothers me is the clearly slower speed for transferring files using windows explorer. With total commander it goes almost double the speed rate. Plus, why should i download a file to my pc instead of downloading it directly to g pad's sd card? Waste of time in my opinion.
But recently i did read somewhere that jelly bean does NOT support usb mass storage, so i guess that answers my question.

[Q] Can't See My Ext SD Card on PC

Ever since I got my G3 from Sprint, I haven't been able to see my external SD card on my PC when I connect with my USB cable. I only see my internal memory. This worked perfectly with my Galaxy S3, but it's been problematic from the get-go with this device. I can see and follow the paths on my device using ES File Explorer, but I don't have that path to click on in my File Manager on my laptop.
If I choose PTP, I can see my pictures, but if I choose MTP, I get nothing. I've toggled back & forth with debugging, but that doesn't change anything. Is it a driver I need to download? I have a 32 gig card, and I want to transfer some files to my pc that I no longer need for this device. I also want to more clearly see what's taking up all my memory, because I can't believe I'm using as much as my Settings/Storage says I am. I don't have a whole lot on here since flashing BarRin, and it says I'm using over 30 gb of internal and over 26 of my external. No way!!
Anyone have a fix?

I am an idiot. I downloaded the drivers, and I'm fine now. If the mods want to delete this thread, that will be fine. Sorry for the inconvenience.

Lineage on S5 - No folders on PC

Hi folks,
Lineage 16 (latest version) is now installed on my S5, however when I connect the USB, the phone just shows as 'SM-G900F' on my W10 PC and cannot be expanded, basically no Phone and Card folders.
I can see them in the phone no problem, but once I connect it, I am not prompted with the usual message on what I want to do, like file transfer etc. and on the left menu appears only the model of the phone.
I had no issues when I flashed the original firmware, so it must be related to Lineage.
I also installed the Android USB drivers, but no go.
Changing the USB Preferences, to PTP or File Transfer only allows me to see the phone folder but no SD.
I also tried a new SD, no success.
Any thoughts?
Thank you,
Alex

I have re-flashed everything and started from the beginning.
lineage-16.0-20190918-nightly-klte-signed + open_gapps-arm-9.0-mini-20190921
SanDisk SD Card 32GB, either way I try to format it does the following:
Phone Storage: attempt to invoke virtual method 'java.lang.String android.os.storage.VolumeInfo.getId()' on a null object reference.
SanDisk SD Card unsupported
Portable Storage: When I hit format, it says: Your Card is ready to use - I click Done but still the cart shows in the Storage area as portable Storage SanDisk SD Card Unsupported
The card is OK, also because if I flash the original ROM the same card works perfectly and shows up in my PC too.
This is very annoying, I am stuck on this for days and even trying other cards I get the same.
I hope you can help me to resolve this matter.
Thank you!
