Where are my file.?please help... - Nexus 7 Q&A, Help & Troubleshooting

I played with carbon. But now when I plug the tablet on my computer I can see only the files for picture.
I remember I changed a parameter like tpi to tpe(????)
Now I would like to revert back so I can access my download file.
Your help is welcome....

For file system access you need to be connected as an MTP device. The PTP is only for media. Also, you need usb debugging turned on in developer options.

On 4.2.1 stock the MTP/PTP toggle control is not in a completely obvious place
Settings -> Storage -> Menu -> USB Computer Connection
Both MTP and PTP leave much to be desired.

USB device Not Recognized

Whenever i plug in my i9000, it just pop up an error msg ÜSB Device not recognized. I'm trying to get Kies to recognize my i9000
I tried following this but it doesnt work at all.
it worked for me on kies, but i didn;t like it anyways
What i did was go to settings --> about phone --> usb settings
and try the other options (i'm using media player option, not sure why mass storage doesn't work)
Did you try to change the usb ports on your pc (stick the cable into different usb ports)?

changing the usb port does help, however when i unplug it and restart my com, it does not recognize it anymore
What OS are u running?
Could also have something to do with the number of irq's on your motherboard.
PC's older then aprox. 3/4 years have less irq's and can have trouble with much external devices

Have a look at this site from HardwareZone.com.
It's heavily populated but you only need to read the last five or so pages.

yeah i am looking at that thread too, however thanks for the link here, good for documentation as well, appreciated
keevy17, u have the phone already? If yes, you could help us resolve our questions in last pages of this thread:http://forum.xda-developers.com/showthread.php?t=694835&page=9
Q: Are there any notifications (on screen, backlight of buttons, ...) about missed calls, new mails, sms? Is there any notification when u charge the battery and the battery is fully charged?
Thanks in advance.
The default USB connection is to activate Samsung Kies. You'll have to go to settings->About Phone->USB Settings to change. If it doesn't work after changing, soft reset the phone and try again.
Caused me a bit of head scratching until I went through the options.
Now am having same problem, can'r see mass storage in my computer.
I think I read you need to enable USB Debugging then it will work. for both of you I believe.
With USB debug i can only use adb, nothing works. If i disable debug i can copy files via MTP protocol but mass storage doesn't work.
Edit.
Found the problem, it doesn't mount it self like Desire/N1 i had mount it my self. All working.

hassan,
I've not yet had a chance to use the phone yet. Can you tell me how you mount the USB in order to use it with a PC?

It was bit tricky to start with as i thought my phone is broke. First go to setting > About > USB Settings > and select Ask on connection. Plug the cable in to the and from drop down notification bar and hit USB connected then you get the option to mount the mass storage.

If you want kies to work with the phone, dont kill MTP.. But kies is acting weird, soemtimes it doesnt see the phone, but after unplug and replug it works again.. I've given up on kies actually, over 100MB to download and worst than some beta software i've used.
also, i cannot get samsung apps to work on kies, it just error or timeout.. you guys hv any luck?
I haven't tried kies yet, i'll try when i get home from work.
Anybody know how to mount on a Mac? I tried changing the USB settings to Mount/Media, no luck. Any help would be appreciated.

Cannot transfer files with MTP / Device not viewable in Windows Explorer

When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.
install pdanet on pc and it will install drivers for u so it will be recognized

Been battling with this on my XP machine since yesterday. I couldn't even get debugging to work until I installed NakedDriver. And even still, there seems to be no way to get MTP to work without turning debugging off. On my Win7 machine everything worked perfectly, both ADB and MTP, right out of the box. I have the Galaxy Nexus drivers installed on both machines (which I've read are compatible with the N7). I also have the latest version of Windows Media Player (I've read that some older versions have issues with MTP). Is anyone else able to run ADB and MTP on XP?
*edit*
A: Does PDAnet let you use MTP and ADB simultaneously? Because I really don't want to install it if I don't have to. I got rid of it ages ago (too many things starting up at boot time).
B: I have a Galaxy Nexus also, and I have no issues on the XP box.
I wouldn't bother with MTP, it's not always showing the contents of the internal storage properly when viewed in Windows Explorer.
Earlier today when I was trying to set up a backup profile for it, it didn't copy all the files off. On closer inspection I found folders like TitaniumBackup to be completely empty, which is not true according to ES File Explorer on the tablet.
I tried connecting MTP again, with USB Debugging on and off but this made no difference. Also I'm only seeing the Notifications folder instead of 36 folders on the internal storage now, really random how it's working.

Same here. No change with the Asus drivers. Still can't use MTP when ADB is turned on.
poo. how do I transfer my audiobooks to this stupid device without working drivers?
1. Please disconnect Nexus7
2. Remove drivers on PC.
3. Toggle ON : Settings->Wireless&Networkings->More->NFC.
4. Re-connect device
Good luck !

1. Uncheck MTP, check the one next to it (Camera)
2. Unplug USB
3. Turn off USB Debugging (Uncheck it)
4. Plug in USB
5. Should say connected as camera, then a new window will pop-up allowing you to see your files.
Tell me if it works!
im having trouble too, is there any way to make the device to be recognised as a flash drive?

Same observation here (a few months later) on stock Android 4.1.1 rooted.
It seems that new files in the internal memory remain invisible for a long time, but so far they have become visible eventually, sometimes a day or two later. I have no clue what could possibly cause this, and I have not found any trick or workaround that makes them visible, not even rebooting. Any hint is welcome.

Didn't work. Just shows up as a camera with the limited folder access one would expect.
Workaround
I now use the following workaround.
Install SDrescan from Google Play.
Run it.
If you already had your phone connected to a computer as a media device (MTP) and are watching the contents of your SD card or internal memory in Windows Explorer, press F5 to refresh your view. If not, connect it now.
I'd be curious whether this works for you as well. If it does, press the THANKS button below.
Same issue with an old ibm x40 udated to windows xp pro SP3.
I've installed mtp driver, without success
I've "tried" to install asus driver, without success
I've tried to do as above with the help of the nexus toolkit, without success.
Everytime, the laptop recognize the device as android ADB interface.
Someone could help me?
Thank you in advance

[Q] mtp vs ptp

Please help if you can
My first 32gb Nexus 7 had no problems showing up as an mtp device on windows 7.
Am running a rooted 4.1.2 and all is well with mtp as well as adb, toolkits, etc.
I purchased one more as a gift, and that one can only be set to ptp in the internal storage settings.
If I try to set it to mtp, it takes, but does not show up in windows or in adb.
The only way to see it or use adb or a toolkit on it, is to set it to ptp which shows up as a camera with read only permissions.
Both tablets are using the same rom etc.
Have tried this on 2 PC's (win 7 as well as xp)
Any Ideas?
Thanks
On my (rooted) Stock 4.2.1 tablet, MTP mode only seems to show up if ADB Debugging is enabled.
Sort of odd; PTP will work whether or not ADB Debugging is turned on, but MTP only shows up when ADB debugging is also enabled.
If you have not enabled "Developer Options" on the tablet, go to
Settings->About tablet
and tap on the last entry ("Build number") 6 or 7 times in succession. This will allow the following menu item to appear under settings:
Settings-> {} Developer options
You can enable ADB debugging from there.
The PTP/MTP toggle control is at
Settings -> Storage -> Menu (top RH corner) -> USB Computer connection
good luck

Thanks, but I guess I was not very clear.
ADB Debugging is turned on but only works in PTP mode.
MTP does not work at all, even though it's checked.

Even after reading this and your 1st post, I am still a little uncertain.
I *think* you are saying that you want to get MTP working on the second unit. And I *think* you are also saying that (additionally) ADB only seems to work when you have PTP mode selected.
Reading between the lines - are you testing things with the same computer for both tablets? (Or, another way to put that, if the answer to this previous question is no, do you see any "Unknown Device" messages in the Device Manager when you toggle things around?)
I fooled around with mine not more than 30 minutes ago. Leaving it plugged into the PC the entire time (Win 7 Pro x64), I could toggle USB Debugging on/off and back and forth between PTP/MTP. Although I didn't actually try a live ADB session in both MTP/PTP modes, the file browser thing would pop up for PTP mode no matter what I had ADB debugging set to, and for MTP mode that would only happen if I had ADB debugging enabled. At no time did I see any unrecognized devices in the Device Manager.
And I think that what I just said above doesn't help you.... arghh.

First of all thanks for the interest.
Bottom line is as follows.
MTP mode does not work period.
However....
when I boot into recovery, (TWRP) the pc sees the usb connection, and I can use adb commands.
So it leads me to conclude that there is something off in the System files. But (and it's driving me nuts)
they are a clone of the first (MTP functioning) Nexus 7.
Thanks again
@OP
You can uninstall the drivers(all of the n7 drivers), then unplug, then replug it in, then let it install its drivers again. This solved the mtp issues other users had.

[Q] Recover Deleted PDF Files - NOT Rooted

Hi
How do I recover deleted PDF files from my Nexus 7 ?
When I connect to Win 8 it comes up as a media device, not a disk so I can't use Recuvva.
When I connect it to a MAC it doesn't seem to do any thing..
Any ideas ? I really need to get these files back !
Thanks
If you were able to switch it to mass storage, it would work, but idk if you can do that without root.

You do not need root to connect via mtp. You do need to have the right drivers installed, the original cable, developer options turned on, usb debugging enabled, and mtp selected. Don't know about Macs though.

I know, but we don't want MTP. MTP doesn't allow it to show up as a disk.

MTP does in fact connect as a disk drive. When I connect I see my sdcard (Internal storage) and all the files and folders in it. I can copy, move, create and delete files, folders, etc. I use it to copy any sort of file to or from the N7. You are confused with PTP, which is a camera interface for pictures, etc.
You can recover deleted files from none rooted android phone, see this solution: Recover data from unrooted android phone
hope this helps.

Internal storage does not show when I connect phone to computer

I have the Motorola drivers already installed and USB debugging ON. But when I connect the phone to the computer the internal storage does not show on the computer. I have to go back to the Developer Options switch the USB config from MTP to PTP and back to MTP to see the internal storage. Just an annoying extra step.
Is there a permanent fix to this? The phone is rooted.
ROM?
Your settings in Developer Options are not relevant. When you connect it to the PC, pull down the notification shade and find the entry that says USB Charging and tap it, then select MTP mode, it should appear in My Computer after that if it doesn't open automatically.
