Fastboot ADB issues using Wugfresh - Nexus 10 Q&A, Help & Troubleshooting

I updated to 4.3, which nuked my TWRP recovery. I have been trying to get TWRP back on my Nexus 10 so I can reroot. The problem is, my computer refuses to see it in Fastboot mode no matter what I do. The drivers are the main issue. I can't get ADB to detect my device in Fastboot.
I have followed all of the instructions on the Wugfresh tool exactly and I still have the same issue. By default, my Nexus shows up as a "Samsung Mobile USB CDC Composite Device" in Fastboot mode. It shows up as an ADB device in normal boot. USB debugging is enabled.
I have tried all of the drivers: Raw, PDAnet, universal, and Samsung. All are giving me the same result. I even plugged my Nexus 10 into another computer and tried the process from scratch and that computer also sees it as a "Samsung Mobile USB Composite Device". Changing the device manually to something like an Android ADB device will still not allow Fastboot to see it.
I'm all out of ideas here. I have uninstalled everything, removed all USB devices, rebooted, tried different computers, etc. Nothing is working. What am I missing?
Update: After several hours, I managed to get my computer to recognize it in fastboot long enough to flash the new TWRP manually and then got rooted from there. What a nightmare!

I am still having this problem. I tried all your steps and I am still having the problem.

Can't get Fastboot to recognise Nexus 7 under Win7 x64

I've tried the latest revision Android USB drivers from the SDK platform updater. I've tried PDANet and the Universal Naked Drivers.
Basically, ADB works great, but as soon as I "adb reboot bootloader", my Win7x64 says "USB Device Not Recognised".
I've already gone into device manager and tried manually updating the driver to the various ones I've downloaded. I've also tried "uninstalling" the driver and reinstalling it, but it keeps coming up as unknown device.
When I type "fastboot devices", nothing shows up (obviously).
What am I doing wrong?

Same thing happening with me, i want to re-lock my bootloader but when i am in bootloader mode windows does not want to recognize the device, i have tried everything too.
Did you install the correct drivers?
When connected and in the bootloader open the device manager in windows. You should see "android 1.0" near the top.
Update that driver. It should work.

Hey, As i said earlier i was having the same problem...try switching your usb cable then try. That is what fixed my problems.
ive done all mentioned above, even tried 3 different cables, no luck, anyone have suggestions
I dont know about what you want to do, but if you want to root and unlock use the wugfresh took kit. Its the bomb and as soon as I figure out where I can thank him and give a big kudos I will give thanks.

I could be wrong, but I don't think adb works from bootloader, but the fastboot command should. I think you can also use Google's Composite ADB Interface driver too for it (I can't reboot my N7 atm or else I'd find out).
I don't have any other android-related drivers on my system either, only Google's USB driver from the SDK. I'm also on Windows 8, but I would assume Google's USB driver would work fine on Windows 7 too.
Also certain USB filter drivers may cause issues too, such as libusb, or even AMD's USB filter driver (however, I had no problems). Or if you want to wipe out any/specific USB drivers, I recommend getting: http://www.nirsoft.net/utils/usb_devices_view.html

I cannot get my phone to show up in my computer or Device manager. I have the drivers install and all. I have tried with usb debugging on and off. I have tried in the Fastboot mode. I have tried after a factory reset.

I'm at a lost as to what I can do....When I try to go to recovery it says "No Command" or something
help me

[Q] nexus 7 bootloop no recovery no usb debug

so i have a nexus 7 stuck in a bootloop, i never enabled usb debugging, and cant get my pc to recognize the device even when it says it's in fastboot mode. bootloader is still locked and recovery mode freezes at google screen on the rare occasions when i can even select that option. tbh i think there's something wrong with my adb setup, but i followed the instructions on the android sdk site... kinda lost here sorry if this question is unclear. i also tried using the unlock option on wugfresh's nexus root toolkit but it keeps saying there is no fastboot device attached. any help would be much appreciated.
never mind, I'm just going to install a fresh motherboard.

Soft brick? (No ROM installed but can sort of boot into recovery)

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

See this on getting fastboot working, best of luck!

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

Soft brick, but can't even get drivers to install

I was trying to install the October security updates on my rooted 6P and thought I did so successfully. However, when it rebooted, it just hung on the Google screen for an hour and I tried to investigate. It appears that I no longer have a recovery or OS and that all I can do is go into the bootloader and reboot the bootloader.
I'm using a Windows 10 64-bit laptop with two USB ports and a USB-A to USB-C cable from Anker. When I started this process, I was able to get my device to appear when using -adb devices-, but now it won't any longer. I've installed, uninstalled, and reinstalled the drivers, both manually and by using both Android Studio and SDK manager (like in Heisenburg's Rooting instructions, post 1, Prerequsites: paragraph 4), but nothing will help it appear on my devices list.
As I understand it, I need to enable USB debugging on my phone, but since I can't boot, that seems not to be possible.
Any help would be greatly appreciated. I've searched dozens of websites looking for suggestions but nothing I do seems to get my phone to appear on the devices list.
Use fastboot from the bootloader instead of ADB. Use fastboot to flash the factory image. Same thread you mentioned.
ADB does NOT work from the bootloader. Only fastboot does.
You use ADB while booted into Android or in recovery. From the bootloader, you use fastboot.
Try again with "fastboot devices" instead of "adb devices"
Hate to say it, but you wasted a lot of your time reinstalling those drivers. If you had it working earlier, I can't see it just stopping. You just used the wrong command. ADB will only ever work booted to the OS or in recovery. Never from the bootloader, even if correctly installed. Same for fastboot, only from the bootloader and never from recovery or booted into Android, even though everything is installed correctly.
Read over that thread you mentioned a few more times. :angel:
Amazing. I have no idea how I could have not known that. Thank you for your help.
Glad you got it sorted!
