if you don't give more info is impossible to answer.. what rom do you use? your sd is working? how is parted? what's your os? adb works? ecc..

the rom i use is hcdr
my sd is working
is is parted with a ext 3
my os is windows vista
i don't use adb so i don't know of it works
do you need more information?

did you installed the tattoo's drivers? have you tried the usb connection software (must be set to usb storage)?

yes i did al of those things but it doesn't work i even did reinstal the drivers and htc sync

Check following path to set if you have already selected some thing by default
uncheck it.
Menu > Settings > Connect to PC > Select Ask me option
Then go to launcher and selected USB to PC
If it says Disk drive then select HTC Sync and Select Ask me option and click Done
when it prompts to choose quickly select disk drive and click OK (you have to be fast here other wise phone would go to htcsync)
If it goes to htc sync cancel and try to change again to sdcard/usbstorage and see if it prompts. or change again to htcsync and try again
I had bad experience with earlier donut builds where it is not easy to connect to PC
If you have already done this and not working then you could access sdcard via recovery

the last tip doesn't work for me neither???
does anyone knows a other solution so i can update my tattoo with htc sync?

Can you explain a bit more on what you did and what happened.
That would help people to understand what is happening.
By the way i have update my previous post with exact menu ( i had to go back to 1.6 rom for a while).
Can you also change you usb cable and see if it helps (if you can borrow from some one)
All the best

when i connect my phone i don't get the message from where to select diskdrive or htc sync i only get that message when i reboot my phone while it is conneced throug usb

As rallapag (almost?!) said, i used to connect it to PC, then enter the app drawer and find that app with a logo showing a light blue screen, maybe called USB to PC. Enter it and select HTC sync.

[Q] Windows 7 fails to install MTP driver

I recieved my N4 yesterday.
When I try to connect it to my notebook (running Windows 7 Professional), the installation of the MTP driver fails. The error message says something like "driver could not be found". ADB however works without problems. (I allready debugged some apps on the phone.)
I tried installing the drivers from the toolkit, but it didn't work.
On my brothers netbook the MTP drivers were installed successfully. But I can't get it working on my notebook.
Can anyone help me?

I was just having this problem but I fixed mine by changing the USB port. Not sure if itll help but worth a try.

Thanks for your help. I allready tried an other usb port. It did'nt work.

I wanted to avoid it but I reinstalled windows. Now it works. Thanks again.

Hmm, messed with this problem for ages yesterday, mtp installed fine in normal mode but refused when in 'usb debugging' mode
simple fix, find your wpdmtp.inf file in windows/inf
edit it like shown, look for the [Generic.NTx86] and [Generic.NTamd64] entries near the top of the file........
[Generic.NTx86]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
[Generic.NTamd64]
%GenericMTP.DeviceDesc%=MTP, USB\MS_COMP_MTP
%GenericMTP.DeviceDesc%=MTP, USB\VID_18D1&PID_4EE2&MI_00
...then update the driver in device manager, use automatic search
just make sure the 'VID_18D1&PID_4EE2&MI_00' matches your device id, check in device manager.. but i'm guessing all nexus 4 are the same.. usb debugging mode

I did a clean install of windows and that solved the issue for me. Thanksfor your help anyway.

I usually see what drivers do install, like adb or whatever, and then remove/uninstall them AND delete them
Then installed this pack
http://forum.xda-developers.com/showthread.php?t=1998650
then connect to a different USB port and try again with the new drivers
Also, some USB hubs can be under-powered and cause problems.

Just FYI, just got a Nexus 4 from T-Mobile yesterday and the device ID is slightly different:
VID_18D1&PID_4EE2&MI_01
01 at the end instead of 00

It doesn't ask. I plug in the phone, and Windows says it can't install the MTP driver.
If I go into Device Manager and find the phone (with the yellow triangle and !) and select Update Driver Software, then navigate to the i386 folder from the Universal Naked Driver (on an i5 system), it tells me that "The best driver for your device is already installed" or something similar.
Of course, if I uninstall the device from device manager (and presumably the bad MTP driver as well), it disappears, so I have nothing to point to to install the drivers.

Earlier today I reinstalled the drivers for my N4 on my work PC (Vista Business) and I had to reboot before it recognised the N4 as an MTP Device - prior to that it only saw it as an 'MTP Device'. Now it sees at 'Nexus 4'

I have a similar problem I have a kindle fire
I have install the ADB driver but am having extreme difficulties getting the MTP drivers to work
I have tried everything (every solution on Google)
and nothing works
I've tried the "Media Transfer Protocol Porting Kit"
I tried to get Microsoft help they gave me the run around and confused me even more
here is the conversation
Microsoft: "Thank you for that information
Nathaniel I was checking your product key and it is blocked that is why you can not connect these devices to your computer, you may be a victim of counterfeit software so in this case since it is an OEM computer which means that the manufacture of the computer installed Windows 7 on your computer I recommend you to contact the manufacture of your computer to see if they have an option in order to resolve this issue you are having."
me: when i contact them what do I ask for?
Microsoft: You need to ask for a new product key
me: I am confused what does this mean? that the manufacturer put windows 7 OS on here illegally? but all PC's come with windows OS so every PC in the world is suspect to counterfeiting
them: No, this could be because someone still some information of your computer and use the product key to try to activate Windows until the product key got blocked
No, the name is not involved in this case it is jut the product key
what do I do?
is there an alternative to MTP drivers?

Solved
Hi, i had the same problem described in previous posts and I managed to solve thanks to what is written by meangreenie.
In practice, in the windows\inf of my Windows 7 the file wpdmtp.inf was no longer present but there is only the "compiled" version (wpdmtp.pnf).
I retrieved the file from an earlier version founded in he folder Winsys and so the LG driver are installed without further problems.

You might be using the wrong driver (Android ADB) instead of the MTP driver. This happened to me the other day!
If you're in Debug Mode, you've already done the first step I was going to suggest.
Here's the second step that worked for me: Open Device Manager -> Click Android Device (top of my list) which exposes "Android Composite ADB Interface" -> Right click that device -> Update Driver Software -> Browse My computer for driver software -> Let me pick from a list of device drivers on my computer -> then choose "MTP USB Device" -> Next
Mine installed the MTP driver and then the N4 opened normally.

That works for me with USB Debug ticked and in MTP Mode but not in PTP Mode (on CM10.2-nightly-20130817). I absolutely can't see my pics in no way... (I suppose this is a bug from Google to be fixed in further updates). ADB and FB are correctly working as tested with NexusRootToolkit 1.7.1 Drivers Test.
May it help to delete original DCIM folder and start from a new one??
edit: Shame on me... I forgot that I've formatted my SDcard, so I've no picture in DCIM folder.... Sorry! So I can say that McDougal trick totally worked for me!

try to check the device manager to check the missing drivers with ! mark

Maybe I'm not completely getting the problem, but just doing this worked fine for me:

Enable USB debbuging in your phone. Go to Settings -> about phone -> tap about 10 times on build number item until USB debbuging is unlocked.
Also, on your computer go to the device manager, look for your phone, if you find it, right click on it, then update Driver Software, browse computer, Let me pick from a list of device drivers on my computer, USB composite device

Nexus 4 not showing up in my computer as MTP Storage

Hi Guiz, So you all probably have heard this a million times but i have tried every i can to fix this. I have tried many options such as Deleting and re-installing the drivers, trying a different usb port 2.0 and 3.0 I have restored my phone. And my phone only comes up as PTP Camera which is useless since i cant root my N4. This problem occured after i updated to Android 4.3. So my question is how can i make my N4 show up as MTP Storage?
I'm running on Windows 8. Thanks in advance.

But since you're here:
1. Enable USB debugging: Go to phone settings -> About -> Tap build number repeatedly until developer menu is enabled. Go there and tick USB debugging.
2. On your PC, go to your device manager (when the Phone is plugged in and set to MTP), locate the phone, right click on it -> properties

If you have problems with driver installations, try this:
2.
Remove hidden existing Nexus 4 or Android Nexus ADB Interface in Device Manager
i had to cleanup the drivers remained after few failed adb driver installations because of the problem in the first step
- (OPTIONAL) Install Nexus Root Toolkit and run it
- (OPTIONAL) click on Full Driver Installation Guide and at step 1
- open Device Manager, click View and select the option Show hidden devices
- now you will see some additional hidden devices (greyed out)
- because i wanted to install the drivers from start i deleted them, that means uninstalled them and added checkmark for deleting local files
- screenshot is attached so you can better understand
Remove the devices that could make problems
3.
- Run Nexus Root Toolkit
- click on Full Driver Installation Guide
- at Step 1 open USBDeview
- in my situation i deleted all the entries with google name
- screenshot in the attach
Final step:
4.
Install drivers for Nexus 4
- Run Nexus Root Toolkit
- click on Full Driver Installation Guide
- at Step 2 i installed Solution #1 - Universal drivers
- maybe you'll need to manually add drivers, if you have an entry in Device Manager that as yellow !
- right click on it - update drivers - browse my computer for drivers - I've added the path to installed Solution #1 - Universal drivers
"C:\Program Files (x86)\ClockworkMod\Universal Adb Driver"
- i repeated it for connection as mtp, ptp and none of that - selection for this is made on nexus: settings - storage - ... in the right upper corner - usb computer connection. so this way the device had installed the needed drivers
- screenshot is added in attach
I've used Wugs Toolkit for installing drivers and after that unlocking and rooting the Nexus 4.
My problem was that there was present HIDDEN ADB Interface under Android Device, after above mentioned steps, my nexus is working properly when connected as MTP device

USB storage not showing up in windows

Anyone else with problems seeing the storage after plugging into PC? adb command works and device drivers installed. Found another forum where turning the usb from MTP to charging and back under developer options does the trick. I have a non stock ROM and seeing if fresh out of the box experiences the same thing.

I have the same issue and can't seem to figure out how to get it to work. My work around has been to use ES File Explorer and open Remote Manager.
Edit: I just plugged it in again to see what I can find. I turned off USB Debugging and Developer Options. Plugged in and pulled the notification bar down, there is an option to change USB Settings to Charging, Power Supply, File Transfers (this works), Photo Transfer and MIDI. Give it a go!

You chose to install the drivers manually instead of having the system do it for you? Right click the yellow exclamation .. update drivers .. allow me to pick .. choose the download file location see what that gives you.

When I choose the location, I see a bunch of options. The most relevant ones are ADB Interface and Android Device. Under Android Device there are several more options such as Android Adapter Interface, Android Bootloader Interface, and the such; no mention of MTP.

So when you change the option in the phone from charging to file transfer, did you check the device manager to see if there any unknown device showing somewhere?

Changing it from charging to MTP shows a MTP device in Manager with a yellow exclamation mark next to it. When looking into the details, it says that no drivers are installed. When I try "Updating Drivers", it says "Windows failed to install drivers. Code 28" or something along those lines. Code 28 MEANS that Windows failed to install drivers.
Thanks for nothing Microsoft.

Nexus 6p Connection to PC Issue - This Helped!
I had similar problems with PC not recognising my Device. I found http://www.technobuzz.net/install-google-nexus-6p-usb-drivers/ which helped me solve my issues.
1. Downloaded and installed the Huawei Nexus 6p drivers. This installed a Huawei Task Manager which connection to pair was still not recognisable.
2. Deleted old drivers (acer, samsung, htc) from' Device Manager'. This actually helped PC recognise my device which showed up in the Device Manager>Other Devices>Nexus 6p, also in PC interface but once moved off charging to MTP, computer didnt recognise device.
3. Downloaded and installed the adb/fastboot installer. Followed instructions till step 10. My screen didn't show anything like Andoid ADB interface, it displayed MTP file install, which I installed. Just remember to refresh in My PC interface when changing over from charging to MTP, sometimes Nexus 6p will be hidden.
4. Uninstalled the Huawie Task Manager.
This has solved my problem with PC and Device connection. The instructions given are from what I can recall of the process I went through.
Credit to Sidharth Rathore from Technobuzz for this solution.
Hope this helps.
Later.
p.s. I have a windows 10 laptop if this helps.

I was having the same issue until I uninstalled some other debugging drivers I had installed. So I would recommend crawling through your installed apps for any other android usb drivers and uninstalling them if you still have this issue.

Working on mine right now. Found that USB 3.0 ports will not recognize device. Once plugged into a 2.0, it is recognized. Might help your issue

[GUIDE] Fix MTP driver installation on Windows 10

Hi guys and girls...
I just recieved my new phone a few days ago. Plugged it into an old Windows 7 x64 laptop and Windows instantly updated the driver. On a 2016 Dell E7450 Windows 10 x64 laptop... It didn't. Tried the Google USB drver package, but it didn't work either. Windows reports about a problem with an INF file and doesn't finalize the driver install...
I just saw someone reported the same issue in Q/A. I thought it would be a good idea to write a step by step guide.

2. Find the file "wpdmtp.inf"
3. Right click the file and click 'Install'
4. Once that is done, simply plug your phone and it should work.

Uninstalled the driver and reinstalled using this method works fine! :good:
If someone has difficulty with the above or it doesn't work (which it should) i leave the one below just in case...

Hopefully, it will help some people.

Awesome, thanks! After several months with my phone, this just happened to me yesterday and I couldn't figure it out. The Google USB driver reinstall didn't work for me either, but this did!
As a suggestion, it's quicker to get to Device Manager by right clicking on the gear icon (Start) and selecting Device Manager.

Hooray... Thanks for the suggestion. I'm such a n00b when it comes to shortcuts... Edited to save the extra clicks.

Hi guys and girls...
I just recieved my new phone a few days ago. Plugged it into an old Windows 7 x64 laptop and Windows instantly updated the driver. On a 2016 Dell E7450 Windows 10 x64 laptop... It didn't. Tried the Google USB drver package, but it didn't work either...
I just saw someone reported the same issue in Q/A. I thought it would be a good idea to write a step by step guide.

Hey... I once had a similar issue with a printer in the past and found this solution on the internet. So when it reappeared with the Pixel, I thought i would try as well. In the end it worked. That's all. I'm glad you sorted it out.

I actually just helped a friend out with this. There is an easier fix then having to go through all that and add a known device.
1. Go to C:\Windows\INF

Nice... Maybe you can open another thread? Or want me to add it to the OP?

Adding it to the OP as an alternate method is fine. Better to keep the information consolidated.

Yeah you're right.
By the way, i just tried to uninstall my computer's driver and installed it with your method! Everything's alright.
Thank you...

My PC doesn't have this file wpdmtp.inf
Uninstalled the device and driver. Reconnected and let Windows update driver. Now it works.

Thank you Soo much. It worked exactly like it says in the OP.

This guide doesn't work anymore. MTP Device and MTP USB Device are no longer the menu options. Uninstalling the device doesn't work. You just end up with the exact same MTP with the exclamation point as before.

Yes! This works! WooHoo.... just had to uninstall all previous drivers first at the device manager.

Thanks, this worked!

Thank you sooo much :victory:, I actually didn't have the wpdmtp.inf in C:\Windows\Inf but I had this folder (link) containing a couple of android drivers and there was wpdmtp.inf file in it, I right clicked and installed it and VOILLAA!!... :laugh: everything went perfect after that. If for any reason you still face MTP problems after this I would recommend to do a manual installation of MTP drivers by going to "Device Manager", click MTP entry with exclamation then "Update Driver Software"->"Browse my computer for driver", navigate to the folder location where you extracted the drivers (link).... you should be done after that. If otherwise you face a problem along the lines of "section in this INF is invalid" while doing manual installation dreboot your PC and find the wpdmtp.inf again, right click then install and you would have fixed your problem. :good:

THANKS!
Oh man! Finally, FREAKING FINALLY, I found a solution that works. Thank u so so so much.

Thank you! This tip worked for me!
I have been having this issue for almost a year, if I wanted pictures and files from my phone, I had to get them from the cloud. Today was the first time in a very long time, that I was able to just copy over files from the phone again from Windows Explorer. THANK YOU!

trying these methods is still failing for me... shows "Pixel" in device manager.. if I try to update drive.. it says either can't find.. or failed...
and if i turn on Transfer Files.. Device manager shows ADB and MTP under "Other" but both fail when trying to update drivers..

YES!!!
