ADB can't find Nexus 7 while in bootloader

Hi everyone,

I am trying to update my (unrooted and unlocked) Nexus 7 2013 wi-fi to Marshmallow via OTA. I have installed adb on my system and download the update package file.

When I connect my Nexus to Windows 10, the system recognizes the device as Android ADB Composite and everything seems to be working as it should. I open a command prompt and type:

Code:

---

adb devices

---

and the device along with its id is correctly shown. At this point I reboot to bootloader, so I type

Code:

---

adb reboot bootloader

---

the Nexus reboots, enters in the bootloader and the following happens:

• adb can't find the device anymore


• the device manager puts the Nexus among the Other devices and so it appears no driver has been installed for it.

As suggested on numerous tutorials, I right-click on the device and choose to manually install an appropriate driver. And I expect to find Android ADB Composite in the list and instead the only possible choice is Samsung Android ADB Interface — which does not work, because, naturally, Nexus 7 is not a Samsung device.

I have tried to solve this issue by installing the google usb drivers using the 15 seconds install and it didn't help at all.

What can I do to overcome this issue?
