Android Fastboot devices not returning device

Question

At the moment I would like to reinstall Android on my device(custom hardware device). I got the image files after building. But when I enter fastboot devices nothing returns.

adb devices is working. It return my device. fastboot flashall -w is also not working. I returns <waiting for devices> and stays like that until I exit.

So the 70-android.rules.d file is right. I have also set ANDROID_PRODUCT_OUT. But someone knows why fastboot does not see my device, but adb does?

Restarting udev or adb does not work. Some people recommend that on the internet.

OS: Ubuntu 11.10

TLDR - In addition to the previous responses. There might be a problem with the version of the fastboot command. Try to download the newest one via Android SDK Manager instead of default one available in the OS repository.

There is one more thing you can do to fix this issue. I had the similar problem when trying to flash Nexus Player. All the adb commands we working fine while in normal boot mode. However, after switching to fastboot mode I wasn't able to execute fastboot commands. My device was not visible in the output of the fastboot devices command. I've set the right rules in /etc/udev/rules.d/11-android.rules file. The lsusb command showed that the device has been pluged in.

The soultion was quite simple. I've downloaded the the fastboot via Android Studio's SDK Manager instead of using the default one available in Ubuntu packages.

All you need is sdkmanager. Download the Android SDK Platform Tools and replace the default /usr/bin/fastboot with the new one.
