[Q] MTP mounting under Linux

I had ICS on a different tablet and had no trouble using mtp with Linux either through the device mounter (KDE/Plasma) or just using mtpfs. With the Samsung 5113 though I "see" the MTP device but it times out. Here's an mtp-detect log:
Code:
Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note.
Found 1 device(s):
Samsung: GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note (04e8:6860) @ bus 2, dev 26
Attempting to connect device(s)
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt
Unable to open raw device 0
OK.
Any ideas? Yeah, I know I can use sshfs and a variety of other ways to get to the device. Just wondering why MTP seems broken.

Bumping this thread ...
I recently upgraded to Fedora 17 and found that libmtp has a known defect that prevents the tablet from connecting. Perhaps you've got the same issue on your nonfunctioning system.
Did you ever find a solution? I now copy files to/from my tablet using scp.

No real solution. Like you, I use scp or ES Explorer or adb or some other mechanism.

I did a little more research this morning and got mtp to work between Fedora 17 and my 3113 tablet.
I did a couple things in total, although I'm thinking the 2nd one was the solution:
1) add vid/pid pair to my 51-android.rules file with 0755 permissions
2) disabled "USB debugging" under development settings. Apparently with that enabled, you can only move files with adb [push | pull].
Now I can connect my tablet to my Linux machine with a USB cable and create files/folders with the Linux file manager.
Hope it works for you as well. Copying with scp over wireless is pretty painful.

Ah. I do development so never thought to try that. I already have the machine in my udev files. Turning off USB debug did not seem to work. I went back and killed my adb-server (which I confess was running) and that still didn't work. May try everything again after a clean boot. But the symptoms were the same.
Still, might be something to it.

The MTP mounted device now seems to work but it doesn't really seem to be stable or fast. I can copy small files easily but large files really don't seem to copy any quicker than scp. I did successfully copy a 1.7GB mp4 movie without any problems but it took almost 20 minutes with mtp/USB connection.

Still can't get it to work. I already had the udev rules and turning off USB debug didn't help. We aren't the only ones with issues. Lots more detail here: http://forum.xda-developers.com/showthread.php?t=1077377
Also gphoto2 has some success in reading info from the "camera" (for example, battery level) but I still can't get it to see any files.

Are you running a stock kernel? I'm running the kernel that comes with CM9. I wonder if that has anything to do with it. Thx for the thread URL. I would like to get a reliable wired transfer solution.

Well, I am semi-stock. It is the 4.0.4 stock with my own init.d add on and rooted. But yes, it is the stock kernel. I keep thinking of switching to CM9 but suspect it will cost me my IR blaster. I don't use it very often but I always think I will But I know it is just a matter of time before I switch.

Even stranger. If you click on the USB options and pick PTP mode, your root directory of internal and external show up and gphoto2 sees it all. But all the subdirectories are empty! So close, but no cigar. gphotofs, as you would expect, sees the same thing.
Update: ok so here's an answer for ADB: https://github.com/isieo/adbfs
Doesn't handle symlinks but on the other hand you can get to the whole file system.
One thing though, adb MUST be on your path for this to work. The adbfs file can be anywhere and it doesn't matter if it is with the adb executable or not.

Changing sdcard file system(for Backtrack 5)

Hi guys,
I want to try Backtrack 5 on our phone, because I need a... school network password . So, I'm using this tutorial. I'm stuck at a part, when I need to put a 4.88GB file to sdcard. Sdcard file system is fat32, so it doesn't support bigger files than 4GB(it gives error when I'm trying to put that file to sdcard). I've got some questions.
1. Is there another way to get a wifi password? (no, apps who try to connect with default router password won't work)
2. How can I change my sdcard file system? What issues can happen? Will phone read it?
3. Why sdcards, usb uses fat32 by default if there is NTFS ?
4. I've got a idea. Instead of changing sdcard file system, wouldn't it be better to partition my sdcard 5GB on ext4(using recovery, I don't really know in what file system it partitions)? What would be easier and better? Would I be able to use it?
Thanks .

Use Backtrack from a live usb on your laptop.
And if you want to format ur sdcard to ext4 then the best bet is to use a live usb with linux and use a tool called GParted and then copy the file to the sdcard using linux. Try Ubuntu

Actually there is a tutorial here on XDA to format your SD card using the NTFS file system..
If you dont wanna do that, you can split the 4.88 gb file into 2 files, using winrar, and then copy them to ur card, and then unrar both files, and merge them.. And VOILA!! There u have it, A 5 gb file copied on your SD card!!!!

Try aircrack ng ....
U will get tutorials on YouTube.simple and fast.and try liveusb for it on laptop

Try to trim that excess gigabyte by removing unneeded drivers. Backtrack is mostly loaded with WLAN drivers.

Thanks for replies. I can't use liveusb on school, because I need laptop(right?). I can't use school computer for this.
bhargz16, tried that, when I'm extracting these 2 files 7zip says "There is not enough space on the disk"(space free is 1.95GB after this error).

explain more, I didn't understand. I can't even open the .iso file .
Trying "Windows, Linux, Unix Emulator" right now...

Use this to download the image on device: https://play.google.com/store/apps/...EsImNvbS56cHdlYnNpdGVzLmxpbnV4b25hbmRyb2lkIl0. , that should work. However you should know that due to driver limitations, it will not be able to do any network monitoring etc., i.e. it won't be able to crack wireless passwords.

Then it's useless! I need to somehow crack it . By the way, "Windows, Linux, Unix Emulator" doesn't work, downloaded FreeBSD, but libSDL closes instantly.

If they didn't give you the password, it's for a reason. You shouldn't be using the network. These sorts of tools are created for testing the security of your own network.
Anyway, it only works if the network only uses WEP security, which most networks don't. Most now use at least WPA2, which is much more secure and won't be cracked as simply.

Heard of WPS exploit?

Compile from source, and when compiling remove some unneeded drivers.

Sorry buddy u can't run aircrack on Android but aircrack is simpleest and fastest wifi password cracker.
I use it whenever needed

Sorry, I didn't hear anything about WPS exploit. And your last sentence looks too hard for me . What if I run linux(using this tutorial) and then run aircrack? Is it possible?

No. If that worked, Backtrack would work. The problem, as I said before, is that the drivers for the WiFi hardware in phones don't support promiscuous mode. Therefore nothing that requires promiscuous mode (e.g. capturing packets, which is necessary for cracking WEP) will work. Unless you use an external USB WiFi adapter along with a USB OTG adapter, assuming you have a custom ROM that supports USB host mode.

Thanks for reply. If I understood correctly, it's impossible to crack a wifi password using our device(without using another wifi adapter)? Even Backtrack or aircrack won't work in all cases? So I can not waste my time formating sdcard to NTFS and etc.?

Transferring files from pc to phone

I have no idea how to do this. When I connect the phone to my (ubuntu) pc, I can transfer files taken with the camera to the pc, but I want to put some wallpapers on the phone from my pc. The phone in MTP mode won't show up on my computer, but PTP mode is no problem. Do I need Nexus Media Importer (from the play store) to achieve this? Stumped.

Thanks, but I get "This app is incompatible with your device."

If you have a router, I suggest using Airdroid or WiFi File Transfer. Both can be downloaded from Google Play Store.

follow post #5 from this thread: http://forum.xda-developers.com/showthread.php?t=2537119
the part at the top of this post about "add to /etc/udev/rules.d/51-android.rules the following code"
and then see if your phone is detected in mtp mode

I use the Wifi router and ES File Explorer. I have LAN on right side and Cloud (google drive) on left side. If i would like copy something from pc, i get it to public folder and copy from here to my Moto G. Make scan for find the Pc in ES.

To enable file transfer between my phone and computer I used this method. I am running Ubuntu 12.04. However, the same guide would not work for my other laptop that runs Ubuntu 10.04. After attempting several different methodsI still can't get it to work. If anyone has been successful getting MTP support on Ubuntu 10.04 please post your method here, it would be greatly appreciated.
cheers :cyclops:

+1 for this. You just need to make sure you made the folder on the PC side shareable to your network.
This also allows easy copy and paste between any cloud folders/PC/tablet/phone/whatever you need without wires.

[Q] cifs on note pro

I have not rooted (yet) but when I run a 'cat /proc/filesystems' I do not see any form of cifs in there. Can anyone confirm if there is any means of cifs support to access network shares?

i'd like to know too. I'm rooted and installed cifs manager but couldnt get it working. I get the message: no such device.
it used to work on my old motorola xoom running omnirom. What is missing?
