[Q]Problem with MTP (and help with a workaround)

Hi
Some background. Like many, I bought a TF700T and like a fool installed the OTA update to JB. I then downgraded, rooted in .30, then upgraded again and flashed SU to keep root in JB. I am now, therefore, running the stock OTA JB ROM, rooted. My bootloader is also unlocked.
Initially after this, plugging the TF700 into USb on Windows 7 (x64) worked fine - the device popped up as a Media Device and I could transfer files on and off it with ease. Now, without changing anything on either end, Windows is refusing to play. It tries to install MTP drivers but fails. If I boot the device in either CWM or Fastboot it connects fine (with adb and fastboot, respectively).
I want to get files on and off the *internal* storage (I don't have an external sdcard)
Things i have tried:
- Using a different USB port
- Using one of the USB ports on the back of the machine, instead of the front ones
- Uninstalling the MTP drivers
- Using the ASUS drivers from the website
- Cleaning out all my old unconnected USB devices (show devmgr_unconnected_devices=1 or whatever) and uninstalling all THOSE drivers
- Cleaning out with USBDeview
- Fresh install of the OTA ROM, after a data wipe/factory reset and wiping cache and dalvik
The only things I haven't tried are a new USB cable (damn you ASUS and your proprietary connector), and a clean install of Windows (major ballache).
Any ideas about what I could do to sort this would be greatly appreciated.
Since I only want to be able to move files on and off the device, I tried a workaround. I tried mounting the sdcard (internal) in windows manually through adb but the command I used to use on my old S2 through adb shell (echo dev/block/mmcblk0 > /sys/devices/platform/usb_mass_storage/lun0/file) but it errors with No such path or similar. I'm unsure if the mount points are different (I guess they will be, can anyone help with telling me what the mount point for the internal emmc is on the tf700?)
Really hope someone will be able to help me!
Thanks in advance guys

I'm in a similar situation except I'm not rooted or unlocked. I've tried just about all the steps you've mentioned w/ no luck. I've even tried to three different PCs running XP, Vista, and 7 and get the same result. What makes the situation even worse is my brand new 32GB microSD card won't read on my desktop as well.

First check make sure you have your "USB debug" and "Unknow software" checked in settings. Then go here and install the pda software for your windows. Once installed, it will installed all the driver for your tab automatically. You don't need to use the software, you can uninstall it later, but the driver will stay.

I haven't picked up a TF700 yet (out of stock locally), so these are just general suggestions...
From adb, shell into the OS (adb shell) and list the directories to try and determine their structure. If the device is booted, the internal SD should already be mounted.
I would start by looking for the following folders:
/sdcard
/mnt/sdcard
/data/media

I had the same problem getting MTP to work on old XP machine. The following worked for me...see post #12
http://www.transformerforums.com/fo...ormer-manual-usb-drivers-sync-software-2.html

Thanks for the replies, everyone. I installed PDANet and was initially hopeful once the drivers started installing. Sadly, Windows still doesn't see my device.
adb shell-ing into the device --> mounts
This lists /dev/fuse as the internal storage. I can't echo this to /sys/devices/usb_mass_storage/lun0/file because when I do it returns "No such file or directory"
The solution posted as working on XP machines doesn't work either.
This is seriously annoying. I'm tempted to just give in and get myself a 32GB SDHC and card reader and just use that instead - at least that way I can move the files across with Root Explorer or something...

Windows 10 USB drivers for oneplus one

Ever since I installed the windows 10 upgrade on my desktop computer, it doesn't recognize the oneplus one anymore. It was working fine in windows 8, and now the device manager shows a USB composite device that is in yellow status failed to start. I have tried pointing the driver update to the google usb driver from the android sdk and that fails, insisting the proper driver is already loaded. Any ideas on this?

if I turn off android debugging on the phone in developers options, it cycles over and over that device is not recognized. I have the samsung drivers from previous posts in this thread installed.

Are you using MTP or PTP? I think I had to move to PTP to get it to work for both access to the storage and for ADB.

What you mean is Bootcamp doesn't support Windows 10 yet. Give Apple 5 years and they may patch it.
Had no problems at all with Windows 10 on 4 machines.

Try to delete Drivers and clean all the install again

I made a clean install of Windows 10, installed the standard Google ADB drivers, then the Samsung ADB drivers, connected the phone to the PC, went to the device manager and replaced the "unknown ADB device" by "Samsung composite ADB device" driver. After doing that, it recognizes perfectly the phone either in MTP, ADB or Fastboot modes with no issues at all. I always did it this way in clean installs of Windows 7 and 8.1 and works exactly the same in Windows 10. Try it this way, it will work.

correct installation oneplus 6 Drivers

after bootloading (for the first time with youtube "highonandroid") after in recovery mode, my windows 10 could not detect my phone's storage.
I could not find the phone in "device manager" setting, and via control panel/printers and devices, there is a oneplus 6, where the update button is inactive.
Where can the official oneplus 6 drivers and software be downloaded, and how can it be double checked if all is installed properly?
I hope to root my phone after I am able to copy from my pc to my phone, to enable stereo speakers and always on display.
thanks in advance! B)

did you use the drop down menu on the phone and put it on 'transfer files' or something like that?

never mind, just found howto enable oneplus 6 in device manager
after connecting the phone with the windows 10 laptop, rightclick on the (not accessible) drive, and update driver.
Instantly shown in the device manager, just unbricked my phone with downloaded software on pc !:victory:

Pixel drivers on Windows 11

Hey there people,
I can't find a solution for this one, so here I am!
I want to transfer files from my computer on Windows 11 to my original Pixel, but I can't find a way to install drivers for it:
Automatic driver install does not work
Google USB drivers aren't compatible with it according to the device manager
Google drivers from the full list of Windows drivers don't work either
The phone is detected as 4 Pixels in the device manager, as well as a disk which isn't readable and returns nothing in the disk management service of Windows.
Any tip will be really greatly appreciated!
Thanks in advance to you all

BTW I tried the usual fixes: original cable, other USB port, reboot, changing the USB management setting to PTP/MTP… nothing works.

follow these instructions brother. The fix for me was to put the phone in fastboot mode before trying to install the Google drivers. You do that by issueing the command "adb.exe reboot bootloader",

Android drivers for windows

I have an rca tablet I can not get any drivers to work to get to replace/update the firmware and I was wanting to ask if anyone has found anything that works.
I have tried mediatek, rca and all other drivers I can find and nothing seems to work on windows 10 64.
Thank You

Thank You will give a try

I have a Windows 7 64 bit system and I am trying to find drivers to access an rca rct6703w13
I have tried every driver I can find and nothing seems to work does anyone know something that will work?
I would be very grateful if anyone could help?
Thank You

Oh boy, I still remember this pain trying to find and use such drivers on Windoze:
- try another port
- try another cable
- try this driver or that one
- try doing a rain dance with 3 days old undies on your head, and turn only clock wise, unless it's full moon, then turn counter clockwise but stop briefly after ever two and a half turns
Maybe, as workaround, you could boot from a linux CD and try your approach from there.
Whenever I flash from my debian, it works: If "fastboot devices" still doesn't show anything then usually I have forgotten to plugin the cable

By using my "Yet Another Universal ADB Driver" Package (see the link in my signature) one can remove all the old adb drivers if that is the issue, but this case seems to be more interesting...
On win10 it seems that the adb is embedded to the winusb driver the same or similar way (registry wise) that my package is using. Now that I have tested, the behavior is similar with my devices. When using file transfer connection the adb is not recognized. With others, charging, photo, midi the abd works fine. To make adb work with file transfer one have to install the correct driver. In this case google's general driver could be okay, one match for vendor and product ids in it ...
https://dl.google.com/android/repository/usb_driver_r13-windows.zip
What I tested using virtual win7 64bit, it seems to behave the same way... which is a bit weird as I've tested it with my driver package. Worked okay then I think. The Android device used has changed since though.. It worked on win10 back then too.. the change has to have happened later.. or I didn't use file transfer..
@steadfasterX 's maid or salt or whatever it's called nowadays might be usable in this case. It's a Linux having SP flash tool etc. available..
edit: tested and it turned out that the updated phone is the problem... using another phone my driver package worked as expected..

1. Don't confuse USB-driver and ADB-driver: the USB-driver since ever is by default part of any OS, so also of Windows OS. The ADB-driver is an extra protocol what allows you to communicate with a phone's Android ecosystem via an USB-connection.
2. Latest generic ADB-driver ( correct: ADB client ) got released August 2022 and is officially versioned 33.0.3.
3. AFAIK a 64-bit version of ADB-driver doesn't exist.
With regards to install this ADB-driver on a Windows 7,8.1,10,11 PC:
It's NO USB-driver installer - as introduced above by @CXZa - needed what unnecessarily bloats the Windows registry with crap.
You
1. simply create on any mounted drive of Windows PC a folder named "ADB",
2. extract there to the 3 files what are in the attached ZIP file,
3. add path of created folder "ADB" to Windows environment variable PATH, thus ADB-driver is systemwide accessible -
how to is described here
How to Set the Path and Environment Variables in Windows
Information on how to set the path and environment variables in Windows 2000, Windows XP, Windows Vista, and Windows 7.
