Yureka fastboot not detected in LINUX, but adb detects device fastboot detects Redmi 2, but not Yureka.

I am trying to install Cyanogenmod in Yu Yureka. When I tried installing the CM zip with default recovery, it failed stating "Signature Verification Failed".

So I tried to install the TWRP recovery using fastboot. I did the following:

root@konoha:~# adb devices
List of devices attached 
2a25599 device

root@konoha:~# fastboot devices 

root@konoha:~# grep 05c6 /etc/udev/rules.d/51-android.rules

root@konoha:~# cat /etc/group | grep plugdev

I get the fastboot screen on Yureka device, but no luck with fastboot devices.

Some suggested that running fastboot as root user solved this. But that too didn't work for me. But for Redmi 2, I was successfully able to install TWRP recovery using fastboot, so that makes fastboot works, but not for Yureka.

I am using Ubuntu 14.04.
Yureka requires the vendor id as a parameter for fastboot.
try the following (tested on yureka plus)


  % lsusb
  
  Bus 003 Device 003: ID 1ebf:7001  
  
  % fastboot -i 0x1ebf devices
