Waiting for device when fastboot flash boot my google glass

Question

My google glass has not been updated. I am trying it from last 10 days. I have followed all the steps given by google ( https://support.google.com/glass/answer/3226482?hl=en )

I have decided to boot my google glass

So,I followed doc ( https://developers.google.com/glass/tools-downloads/system ) but i am stuck on below command

techno-30@techno-30:~/Dhims/SDKupdate/sdk/platform-tools$ sudo $(which fastboot) devices 015ECD7119006014 fastboot

techno-30@techno-30:~/Dhims/SDKupdate/sdk/platform-tools$ fastboot flash boot boot.img < waiting for device >

i have tried two times but always waiting if device is connected.

thanks..

Answer 1

First put the Glass device into fastboot mode:

adb reboot bootloader 

Unlock the Glass device if locked:

fastboot oem unlock 
fastboot oem unlock

(yes, you need to issue that command twice)

[Optional] wipe the device- If the device was not locked (the above command will tell you) then you may want to wipe the user data partition to start clean, if so issue

fastboot -w

Then, Flash each of the partitions. Ex. For boot.img

fastboot flash boot boot.img

I hope this will work. Tried my side working fine.
