[Q] Nexus 7 (flo) not connecting to PC????

im not sure if ive been looking in the wrong places but i cant find an answer to my problem. so i rooted my nexus 7 about a week ago and installed twrp. everything was working fine until i accidentally pressed wipe data instead of factory reset. i deleted EVERYTHING on my tablet including my operating system, the only thing left was twrp :crying: today my otg usb cable came in and i installed that unofficial cyanogenmod build and now it wont connect to my pc. i have usb debugging on and everything. i go to device manager (on my pc) and it is listed as "Nexus 7" but when i try to install the usb drivers it says that they dont work for it. how can i get the usb drivers to work again?
Note: its not my pc cause my rooted s3 works just fine with my pc.
sorry for being a noob! and thanks for the help!

I actually have the same issue where my Windows won't let me navigate my N7 as a portable device. Tried a whackload of drivers and the like to no avail. To transfer files I just end up using ES Explorer. Funny enough, ADB in recovery works just fine.

If it is the same as PA and PAC, try Settings > Storage > Press Menu > USB > Check MTP

Were you on stock before you wiped? Trying going back to stock and see if you can get MTP working, then start introducing the parts until you figure out what broke.
The USB IDs for the MTP device change more often than you'd expect causing recognition problems.
For example, on stock, with USB debugging enabled, it advertises one USB ID and also sends out a MTP-compatible flag. When USB debugging is disabled, a different USB ID is sent, minus the MTP-compatible flag.
I helped someone on a different ROM force the MTP device drivers to associate, but then the drivers couldn't initialize the device. This might indicate there is a problem on the ROM side.

If your ADB works in recovery then you must have installed some other adb device driver, other than Google's, at some point.
If you want I can try helping you get things recognized on this thread

PC won't recognize internal memory

OK so i did the wugs toolkit for the n7 2nd generation but I think when it tells you to take out all drivers of any nexus device I think I took out to many because now after rooting it and it works fine so does adb and I have that installed I connect my n7 to my PC running windows 7 and I can't recognize the internal memory when it shows up in a little window And you open up the folder and such and it says internal memory it doesn't even say that please help was working not it forever also I thought because I didn't have device connected as a media device checked I thought that was the problem but the window for the option to open up the internal memory to move ROM files and such still doesn't show hopefully you guys can help me out please also sorry if you can barely understand.
PLEASE HELP

Have you tried disabling USB debugging and enabling MTP mode?
You can also try the MTP driver inf here:
[FIX] MTP with USB debugging / ADB within Recovery (windows/nexus7)
You can also try using USB Deview to uninstall the drivers and have everything reinstall. Sometimes that kicks everything into gear. Just sort by creation date and uninstall everything that says Nexus 7 in the last few days.

[Issue] Nexus 7 2013 Cm installed ADB & USB Debug problem

Hello, as topic title, I have some issues with my nexus 7 2013 wifi model.
I installed official cyanogenmod 10.2. I would like to restore factory image, but i have some serious issues with adb drivers while usb debug is on.
I installed official google adb drivers, drivers from nexus root toolkit (not all toghether), but when i connect my nexus 7 to my pc (running windows 8 64 pro) there is no way to make him recognize my nexus, and all adb commands fail.
If I disable usb debugging and activate mtp, my pc recognizes the nexus 7, but still can't see the nexus itself in 'my computer'.
i need some help please.

You only need fastboot to flash the stock system images.

that does not completely solve my problem

Restore the stock ROM to see if USB Debugging and ADB is working correctly.

Are you saying your issue is you want adb and mtp to work at the same time and you have them working individually or are you saying you want to restore to factory images? If the latter, the previous poster already gave you the info you need.
Just boot into bootloader using Power Down, then press/hold Power+VolDown

[Q] My computer not recognizing MTP AT ALL

Hey guys. I been here for like 4 hours just dabbling with everything. And cannot seem to find any solution to this...
I have uninstall all drivers and restarted like ten times now doing the same process over and over, cleaning up each file carefully of the nexus or any android device.
My problem is when i plug in my nexus 7 2nd gen, it seems to not even detect squat.
I have usb debug enabled
my MTP is on
( if i switch to PTP i can access the folder)
Ive done fresh start on everything i even look through device and try changing the option to MTP and STILL DOES not work
I don't even see my nexus 7 in my HDD external or anything, nothing pops up but an ADB success driver, and when i changed it to MTP a MTP success driver with STILL no luck....
I just bought it today and it worked fine earlier, now when i root it and stuff it seems to be glitchy with my MTP
I even factory reset everything i couldn't access my ADB
any help would be appreciated

Someone said that manually updating the adb usb driver in devices should show you a choice, choose mtp. It should then sort itself out properly.

On your Nexus, open "settings", click on "Storage", click on options(3 vertical dots on the top right corner), click on "USB PC Connection", now check MTP option.
Try connecting to your PC (or Mac) now. I didn't have to do that on a stock build, but for some reason I had to do it on a couple of custom roms. Hope it helps ya out...

Try enabling USB debugging. I know it sounds odd but its helped me with my devices.

do this only if you can see PTP on PC
On PC check device manger, on Android if there is ADB driver - uninstall it
On N7 set to MTP, debug off and reboot with N7 USB cable connected to PC
It should re-install the ABD drivers on PC before N7 fully boots up
You will be back in action.

Actually for me, it's the opposite. If usb debugging is on I can't access the device to view files. Try disabling it?

yea thanks though everyone I got it to work. I had my old nexus and new drivers mixing up my ports for some reason not being able to access it at all

[Q] Rooted Nexus 7 Unique MTP Issues

Ok so I have a rooted nexus 7 that won't show up as an mtp device ever since I rooted another nexus 7 on the same computer. I have uninstalled all the drivers and re installed them a million times with device manager and USBDview nothing works. It connects to other computers as an mtp device, however ever since I rooted the other nexus 7 on the same computer it won't work. Also I don't have access to the other nexus because it was my friends. Obviously it's a computer issue because it connects to other computers as an mtp. I'm really out of things to try as I have searched for this problem, but only found people saying to re install the drivers. I would really appreciate some help because I don't know what to do. Thanks.

I also have weird issues. What I usually do is make sure the Nexus is configured for only one connection. So for MTP mounting I have PTP unchecked and USB debugging unchecked. Then I plug into the computer.
If it doesn't mount as MTP, I find it's usually because Windows has attempted to connect via ADB drivers. So I go into Device Manager and uninstall the device under "Android" while checking the box to remove drivers for the device. Then I unplug the Nexus and plug it back in, and it uses MTP drivers. I've always struggle with these driver issues for the Nexus, i don't know why it's so difficult. Good luck!

When I had issues with my mtp I had to uninstall adb drivers then plug my device back in so it would use mass storage and install the drivers. Somehow I have adb and mass storage working now with USB debugging on.
Check in device manager when you have adb uninstalled and see what your device comes up as.

I uninstall the adb drivers but for some reason windows automatically installs them right back instead of mtp drivers and then if I go to update drivers and select mtp as an option it says it won't work

When I try to install the mtp drivers it says "Windows found driver software for your device but encountered an error while trying to install it...your device can't start" Then it automatically installs the adb drivers. What would be the reason it won't let me install the mtp usb drivers? Has anyone else encountered this?
