Where do you toggle from MTP to PTP?
[Nexus 7 Q&A, Help & Troubleshooting] GedBlake:
Hi, Bootlejr88...

When you hook the Nexus 7 up to your PC, a message should appear in the notification bar.

Dragging this down, yields a menu with two checkable tick boxes, as follows...

****************

USB computer connection

CONNECT AS...

Media device (MTP)

--- or ---

Camera (PTP)

****************

...and select accordingly...

Hope this helps.

Rgrds,

Ged.

Din you solve the problem? Mine is also can't work with PC. Even can't charge while my n7 is turned on.
[Nexus 7 Q&A, Help & Troubleshooting] makalele2:
I've got a problem with my Nexus 7. Mac OS cannot see it. It just only charges. Not even prompting me to choose PTP or MTP (Tried to change to PTP in storage options too). I've got development mode on. It's working without any problem on windows 7 (I was debugging some my apps too). Cable is ok, because other devices are working (Samsung Galaxy S3 for example with android 4.3). Using android 4.4 and mac os mavericks.
[Nexus 7 Q&A, Help & Troubleshooting] Blind Absence:
FIX! I hope :)

Hi all,

I just recently come across this problem,

rooted my device and then the MTP wouldnt work.

to fix it do the following:

1. Make sure MTP is ticked (settings - Storage - Tap the 3 dots in the upper right corner - Usb computer connection)

2. Go back to settings and scroll down to Developer options. and click it.

(if you don't see developer options, Settings - About tablet - and tap the build number until it appears. then go back and tap it)

3. make sure the device is connected to your computer and make sure the USB debugging is checked.

4. open up device manager and right click the device and click uninstall.....

you may find it is connected in ADB mode, to locate it unplug your device from the computer and reconnect. you will see it show up (will show up under something else)

mine said acer ADB, your may say something else. find it and uninstall it.

5. unplug the usb cable.

6. Go back to Settings - Storage - Tap the 3 dots in the upper right corner - Tap Usb computer connection and uncheck Media Device (MTP)

7. Go back to developer options and Uncheck "Usb debugging"

8. At the top of your screen you have a On-Off switch yours should say on, turn it off.

9. Go back to Settings - Storage - Tap the 3 dots in the upper right corner - Tap Usb computer connection and Tick Media Device (MTP)

10. Reconnect the cable

DONE! :) Hope this helps everyone who is stuck. :good:
[Nexus 7 Q&A, Help & Troubleshooting] nemesi54:
Had the problem and what i did and worked was:

With the device connected and the debugging and MTP TICKED went to device manager and my nexus was showing as Android Phone ADB device.

Right click that and go - properties - driver - click uninstall at the bottom and in the next window TICK also "Delete the driver software for this device" and hit OK.

When its done disconnect the device and reconnect it.Let windows install the driver and all will be fine.

That worked for me and now my Nexus shows up at My computer as always and the ADB works also

NOT an USB DRIVER issue

Please guys,

This threads is filled up with the same fix again and again about re-installing USB drivers or messing with MTP setup.

It seems a bunch of us have real issues like the OP and this thread is now over-polluted with false solutions.

Anyway, I have the same issue:

* I use Linux (for 13 years now), NOT windows

* Nexus 7 2012 wifi only

* can charge on USB

* can mount USB keys using an OTG cable

* NOT seen on any computer (tested on my girlfriend's windows as well)

* tested with 4 different USB cables, all known as working with other android phones

Thus, I cannot flash anything through USB fastboot or adb and the Recovery mod has been erased by the official one on my last update to 4.3. The official Recovery mode only has the ADB "sideload" flash that I can obviously not use without USB.

I tested the following solution from page 21st with no success:

http://xdaforums.com/showpost.php?p=47862239&postcount=208

My nexus is not under guaranty anymore so I can not make it repaired.

Does anyone tried to fix this issue by replacing the USB port itself ?

Any other real solution / idea ?

Thanks a ton guys

I found this video.

Mine would charge but that is it. So fortunately it was still under warranty. I even had the bootloader unlocked & Asus still fixed it.
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:
Thank you for the link, I found it as well before my first post.

Still, considering the OTG cable works fine, I really wonder if I really should change the USB port (AND the jack as they come together) for ~30£ or if I should change the MB directly ~55£.

Do you have any clue of what they fixed on yours ?

Thanks,
[Nexus 7 Q&A, Help & Troubleshooting] jadesse:
I had to send mine in twice. The first time they replaced the mainboard & the issue came back about a month later. The 2nd time I sent it in they replaced the USB port/audio jack depicted in the video.

Dodgy connection

I have 2 Nexus 7s and one charges and connects to the PC fine, the other charges ok, but when it connects to the PC it goes off and on. I sometimes get a message that the device can perform faster if I connect it to a USB 2.0 port (which the port I'm using is!!). Seems like a faulty connection or something?

I'm going to try electrical cleaner spray later when it arrives in the post, but wondered if there's anything else to try? Don't particularly want to have to change the ports if I don't have to!
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:
As the USB/jack board sounds to work fine (data with OTG and charging works fine), I just ordered a refurbished MB for 53.15€ on ebay.

If changing the MB works for me, at least we can exclude the USB board as a problem. We'll have an answer in ~15 days.

Hello. Just went through the available posts.

No solution works. Problem is simple: device not visible under device manager in windows whatever is the combination of tablet settings, cables or even OS (tried win 8 and XP).
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:

Yes it charges, and battery indicator is showing charging status.
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:
Well, so I guess this is the same problem than mine.

Best bet for you would be to send it back to the constructor if it is under guaranty.

On my side, I still wait for this refurbished MB to try to fix mine myself...
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:
So I receive the motherboard yesterday and replace the old one today. It works now ! So it wasn't the USB/jack port.

Fixed mine for ~50€ on ebay. If you try to change your MB, be sure to have phillips #000 AND #0000 screwdriver. I couldn't find a #0000 screwdriver in shops today, so I had to ask a guy in a phone repair shop.

Anyone found a solution for this ? I'm in the same situation .. the pc doesn't see the tablet, sometimes is play that sound when I connect the tablet, but sometimes not even the sound. In device manager nothings appear, the adb and fastboot doesn't see the tablet.
[Nexus 7 Q&A, Help & Troubleshooting] fimfadimpa:
My Nexus 7 ended with negative RMA - it wasn't accepted because of oxidation on logic board, specifically at modul for Wi-Fi and Bluetooth. Since then USB connection didn't work at all and I also had problems with charging, so I've sold it for repair and ended with this crap. I don't want anything from Asus again!
[Nexus 7 Q&A, Help & Troubleshooting] ioguix:
if it is always charging, your USB port is fine.

If your computer make some sound when you plug the tablet, at least it react to something. So it sounds like a driver issue. There's many thread about that all over the forum.

If it react sometime, or when you mess a bit with the cable, maybe you have some bad contact, thus, USB port is dead/broken. There is a thread around about someone that fixed his broken USB port by "bending" it back.
[Nexus 7 Q&A, Help & Troubleshooting] jadesse:
Yes, if you are hearing the sound sometimes when you connect your Nexus then it is most likely the USB port. If you are not under warranty then replace the whole assembly yourself. It might be worth a shot.

It could be the mainboard as I have had mine replaced for this issue. What concerns me thou is that sometimes you hear the sound when connecting your device.

Windows XP does not recognize Nexus 7 MTP

Hi,

I have a Nexus 7 2012 (no rear camera) and I rooted it with the Nexus Root Toolkit. After I did this and installed their drivers, I could no longer recognize the Nexus 7 from XP Explorer.

I have read many threads and posts, downloaded google drivers, ASUS drivers, updated Media Player, and modified the wpdmtp.inf file as suggested and I still can not see the Nexus 7 in the MTP mode with USB debugging checked or unchecked.

PTP works fine.

It seems this is a common problem, has any one found a solution?

Thanks for your help.

Driver conflict problem?

So I have this problem, which only occurs on computer that I have also installed my HTC phone on. On any other computer it works fine, so I am assuming it is a conflict with the HTC drivers (and perhaps other android device drivers or management software). It also works if I switch it to PTP mode, so its definitely not a cable, USB port or mobo problem. Sounds like many of you are having similar issues. Anyone have any ideas how to use this device with a computer that is set up for my HTC phone as well? Would rather not use PTP mode...

More specifics: When in MTP mode it shows up under device manager under USB controllers as "Unknown device" and trying to install drivers fails. When in PTP mode it shows up under Portable Devices as Nexus 7, as it should, so this seems like a pretty ridiculous issue...

Any ideas or help would be appreciated. Have tried the clockworkmod universal ADB driver, no change...

---------- Post added at 10:10 AM ---------- Previous post was at 10:06 AM ----------

Hey mate, do you have any other android devices, drivers or management software installed? I am having the same problem but only on certain computers where other android devices are (sometimes) present. Will post more in a sec

---------- Post added at 10:43 AM ---------- Previous post was at 10:10 AM ----------

Unfortunately this fix doesnt work for me because it doesnt show up as an Android device like it did in your case, it shows up as an unknown USB device...ADB doesnt recognise it as connected (devices command lists nothing). Any ideas how to progress to your initial stage?

MTP Failure

Hi,

On my device manager, when I plug in the OTG cable with MTP and Debugging enabled, my device manager is updated to show ANDROID PHONE and directly under it, GOOGLE NEXUS ABD INTERFACE. I do not have any other Android devices on this computer.

I had rooted my Nexus 7 so I could have access to SD cards through the USB cable so I can download files from the geocaching site geocaching.com to my Garmin 450 GPS - this is working fine. I'd like to use MTP to transfer fines from my PC to the Nexus, but worse case I'll be able to put files on a SD card and then put the card on the OTG cable and use a file manager to transfer the files to the Nexus.

If possible I would like to enable MTP so I can transfer any files to the Nexus without doing the above.

The MTP problem seems to be very common, you would thing someone would have a solid fix by now.

Thanks for responding,

Wayne Miller

Found a SIMPLE SOLUTION

I have had this same problem - a Nexus 7 2013 that suddenly stopped being recognized by the system. I hadn't been charging it in a car, but I was using it on different computers via USB to do some app testing. Well, suddenly it just stopped being recognized. I don't know what I did, but by the mercy of God, I found that in the Settings > Storage > [three dots option icon] > USB Computer Connection leads to a screen with check boxes for MTP and PTP modes. BOTH were unchecked. When I simply checked the MTP box, it went right into MTP mode and started being recognized! WHEW!
[Nexus 7 Q&A, Help & Troubleshooting] Rhian:
Something must be fried in mine, it suddenly stopped charging while booted. This was what made me check the USB port.

It isn't recognised by my PC, it doesn't charge from charger or PC.

Logcat says nothing when plugging or unplugging the USB to/from PC.

I have tried 5 different USB cables (and four different chargers to charge it while on).

Now the weird part is that OTG USB transfer from N7 to memory stick and back works fine. The unit charges when powered off. Fastboot works from the bootloader... :confused: ADB does not work in TWRP (neither does charging, the + is missing behind the %)..

If I want to change a setting in the USB mode (MTP/PTP) the unit resets, makes a weird pop and boots up again. (It's on MTP and can't be changed). :crying:

I also tried disconnecting the battery and leaving it for half an hour (as I found as a possible solution somewhere), but no luck with that either.

I tried reflashing the bootloader (in case it was something in there). I tried using stock and another (previously working) ROM from backup. All no luck!

I really would like to be able to charge while having it booted. The PC connectivity is a minor issue for me, since fastboot still works.

It kinda behave like mine and some other guys around this thread. Sadly, this thread has been poluted with tons of false MTP or driver problems :-/ ...

[Nexus 7 Q&A, Help & Troubleshooting] Captain Sweatpants:
I had this exact problem it was caused in my case by a faulty charger that was putting out 15volts.

The Nexus 7 has two separate charging circuits one while powered on and one while off. You have fried the powered on circuit that's why it charges while off. You need a new motherboard.
[Nexus 7 Q&A, Help & Troubleshooting] midego:
The most direct way to connect a Nexus 7 to a computer is by using a wire — specifically, the USB cable. You can do lots of things after making the USB connection. It all starts with connecting the cable.

The difference between the MTP and PTP connections are in how your computer recognizes the Nexus 7. If you’ve set the USB connection to MTP, the computer is fooled into thinking that the Nexus 7 is a portable media player. For the PTP connection, the PC believes the tablet to be a digital camera.

Determining whether the Nexus 7 uses the MTP or PTP connection is done by following these steps:

At the Home screen, touch the All Apps button.

Open the Settings app.

Choose Storage.

Touch the Menu icon button, and then choose the command USB Computer Connection.

The two options are MTP and PTP.

Ensure that there’s a check mark by the Media Device (MTP) option.

Touch the Home navigation button to return to the Home screen.

You should use the MTP connection because it’s the most flexible. If you find the Nexus 7 not recognized by your Windows computer, rework these steps and choose the PTP option.

MTP stands for Media Transfer Protocol. PTP stands for Picture Transfer Protocol. Do not bother memorizing these terms.

Grrrr!!! I can get into fastboot and recovery fine! fastboot drivers loaded great. ADB?? Hell no!! This is sooo frustrating. There is nothing wrong with the USB cable. It connects and cant find a driver. When I try to UPDATE the driver with the one supplied by ASUS, it says no drivers found etc.. if I delete the device, and scan for changes, it loads the same damn non functional driver and shows an error in device manager.

[Nexus 7 Q&A, Help & Troubleshooting] devastatorx:
From recovery are you able to access the tablet over adb? Can you mount usb storage from recovery? You could also try flashing a different recovery from fastboot to see if the previous methods I mentioned work with a different recovery. You can also try wiping cache from fastboot to see if that cures the boot loop. If none of these options work you can try flashing each individual partition (system etc..) through fastboot.

Edit: I re-read your post and you said you had to flash boot.IMG (a kernel). You can try flashing a different kernel and wiping cache and dalvik to see if that clears your bootloop also.
