ok, trying to follow the instructions to sideload the OTA update to kitkat here:
http://www.androidcentral.com/how-manually-update-your-nexus-tablet-kitkat
However, I am running into a problem with the recovery mode. it isn't seen by my PC. So adb cannot find my device to let me sideload the OTA.
adb sees my tablet when it is running normally, though. I was able to reboot into recovery using adb. It just lost the connection as soon as I was rebooted in recovery.
Does anyone know how to make windows see my tablet while it is in recovery mode?
Thanks,

You need to pull up the recovery menu by clicking the power button and then clicking the volume up button and then letting go of both of them. then click the button that says something along the lines of sideloading an update via adb and then you're set to send the adb command. Be wary, however, I seemed to somehow brick my N10 earlier by doing this. I finally got it up and running (by what I'm calling luck) but it wasn't a fun hour.

I can get to recovery, no problem there. I can select the option to sideload via adb. the problem is in Windows. Once my tablet is in recovery, the tablet is no longer seen by Windows, so the adb sideload command fails because it doesn't see the tablet is connected anymore,

I've heard that unplugging the device from the PC until you're in recovery mode might help. I would also suggest, if that doesn't work, to install the ADB drivers again once you're in recovery mode.
Go to device manager and you will probably see "Nexus 10" listed with no drivers installed.
Right click it an select properties, then Driver. Click Update Driver.
Select the browse option, then let me pick option, then click "Have Disk" and point it to the folder sdk\extras\google\usb_driver from the Android SDK you installed.
Then select the Android ADB driver.

When it is running, and usb debugging is enabled, it shows up under Android Phone as Android Composite ADB Interface.
I turn USB debugging off, and it shows up under Portable Devices as Nexus 10
I boot into the bootloader and it shows under Android Phone as Android Bootloader Interface.
but It doesn't show at all when I am in recovery
How are you connecting your N10 to your Windows machine? Are you using good USB cable? Are you using USB2 or USB3 port? Is the port attached to mobo directly, or is it on the case?
Some claim there can be issues with poor USB cables, using USB3 instead of USB2, or using port not directly on the mobo, so if you're doing any of those, I'd suggest trying a switch.
Also, I'm confused, has USB debugging on or off when you go into Recovery?

I am connecting with a USB cable. I don't know if it is "good' or not, but it works with the tablet in all other modes. I was able to use adb to transfer files, reboot, etc. I was able to use fastboot to flash Chainfire's autoroot, and to flash the factory images.
I was using a USB2 port directly on my laptop, but I just tried the USB3 port and it didn't change anything.
Plugging it into my USB hub, and my hub did not detect that it was plugged in either while it was in recovery mode. It was detected when I rebooted back into the system.
USB debugging is on when I enter recovery. I used "adb reboot recovery" to reboot my tablet into the recovery mode

Sorry, noob here. Please help!
My computer keeps on installing the wrong drivers everytime I plug in my Nexus 7. I don't know how to stop it.
When my tablet is in bootloader mode, Windows will try to install a bootloader interface driver that does nothing.
I have already:
- Went to Devices and Printers Installation settings and clicked on never install driver software
- Went to gpedit.msc and enabled: Prevent Installation of Devices not described by other policy settings,
So now my policy will block the auto install. But when I try to manually try to try Naked Drivers, it'll say it can't find any drivers.
When my tablet is in normal mode, the adb drivers comes back on.
I'm just trying to boot to recovery so I can install a new rom through the command prompt. Current rom is too unstable to do anything, new rom is already on the internal sdcard.
If any has any solutions, please let me know.
Thanks!
It sounds like you did things to prevent driver installation. But you need to install the correct drivers for things to work. Getting the correct drivers installed seems to be the biggest issue people have in being able to connect to a pc or use adb or fastboot. I know I installed the drivers from a root toolkit, installed rsd lite, android sdk, motohelper, etc. and still couldn't connect. Then I installed the pda.net app on the N7 and installed pda.net for android on my pc. Finally it worked and I can reliably connect to the pc, use adb and fastboot, and recognize the N7.
If all you are trying to do is get into recovery, why don't you just power off, hold the vol down and power until the screen comes on, use the up vol to change the menu to recovery, then hit the power button to enter recovery. Then you can wipe and flash. I hope I got those commands right. I'm using cwm recovery and I can get there like that. Usually, I just use Rom Manager to boot into recovery.
pdanet was what worked for me as well. none of the others did.

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?
Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.
And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.
OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.
OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.
--edit--
I've solved my issue

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

Try turning off usb debugging. My tablet cannot connect to pc but with usb debugging off it at least recognises tablet as a media device and this enables me to view its files
.but still the problem of not being able to root
Hi,
When entering recovery mode on the Nexus 10 (Android 4.4.3), when I connect the tablet up the a computer it does not detect a USB device. This is not the usual driver related issue - nothing shows up in device manager - it is as though the USB cable isn't even connected. The usual sound from Windows when you connect a device does not sound.
I can connect fine when the Nexus 10 is booted, and I can call "adb reboot recovery" and the tablet reboots to recovery, but then there is no USB connection.
To reiterate - there are no driver issues as I'm not even getting as far as loading a driver! I've tried two different computers (Windows 8.1 and Windows 7) and two different USB cables.
Anyone seen this before? Why is USB disabled when in recovery?
Thanks,
Gary.

Thx Josh
Figured this out thanks - turns out "adb reboot recovery" doesn't put the device into a state of waiting for a sideload - you have to do a further press of POWER+VolUp to bring up the menu then select sideload via ADB - the USB then kicks in! Doh.
howdy y'all,
so im trying to help out my buddy. he currently has no os installed as well, but can boot to bootloader and twrp recovery 2.5. no idea how he has that but I figure I could just mount some zip files and be on my way. Currently whenever we try to do anything in twrp(ie wipe/mount) it is just hung up on unable to mount /radio even when all I have checked is system. I can't use adb or fastboot as far as I'm aware of; I've tried to use the unified android toolkit from skipsoft but its no dice since I was never able to turn on debug mode to begin with? So yeah any help would be much appreciated
oh and I know its not my cable or usb ports since the tablet can still charge.
Also this is the 2012 N7
Hi,
You'll need to get adb and fastboot working, best approach is to wipe and flash factory images through fastboot but may also need to use adb for e2fsck

I don't understand how I'm supposed to get fastboot working since I was never able to enable debug mode on the device in the past let alone now that it has nothing installed. And from what I can understand from the instructions I need the drivers to be installed after I plug in while under debug mode for the sdk to work.
I attempted to install the nexus 7 driver from here: http://support.asus.com/download.aspx?SLanguage=en&m=Nexus+7&os=32
However it looks like I already have the files on my computer from a previous attempt with Skipsoft's Android toolkit?
Because of this I'm unsure of how to move forward with this fastboot business.
fastboot doesn't need debugging on or an os installed, just a functional bootloader
You will probably need to manually update the drivers yo the proper ones
I see, how do I go about manually installing this driver then? I'm assuming I need to go through some sort of windows device tree? Or can I just extract a file somewhere?
You can download usbdview (just search Google for a free download) to see what driver is selected when you plug in your tab easily
Or you will need to go into device manager and select to manually update the drivers, don't allow windows to select but manually choose it
There are loads of instructional videos on YouTube for you if needed
I know this is a super late response, but I never managed to get around to trying to find out how to do a manual install. Just tried today using the Nexus Root Toolkit v.1.9.9. I still can't figure out how to manual install the driver because my issue is that windows doesn't recognize anything is plugged in, and all of these guides do state that I should have had usbdebugging checked. I can't seem to find a specific guide that correlates to setting fastboot up exclusively like you mentioned.
Also, using usbdeview like you said I could see that I have installed a google nexus adb interface, a google galaxy nexus adb interface, as well as the mtp usb driver.
Sorry for all the handholding, but this really is an issue that I've never have encountered and I can't seem to manage.
Hey again
There is a fastboot guide in the first post I linked you to
If you can't get fastboot to recognize device in bootloader mode it is possible the USB port is broken, but more likely an issue with drivers, cord or PC
So try a new USB cable, or a different PC
Try try again with drivers, uninstall and reinstall
Unfortunately this type of trouble shooting is hard to do without device in hand
Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.
I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.
you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?
I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.
