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:~# lsusb
Bus 003 Device 002: ID 046d:0825 Logitech, Inc. Webcam C270
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 002: ID 046d:c534 Logitech, Inc. 
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 05c6:9039 Qualcomm, Inc. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 009 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 008 Device 002: ID 0bc2:5071 Seagate RSS LLC 
Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

root@konoha:~# adb reboot bootloader

root@konoha:~# fastboot devices 

root@konoha:~# grep 05c6 /etc/udev/rules.d/51-android.rules 
SUBSYSTEM=="usb", ATTR{idVendor}=="05c6", MODE="0666", GROUP="plugdev"
#SUBSYSTEM=="usb", ATTR{idVendor}=="05c6", MODE="0666", GROUP="plugdev"

root@konoha:~# cat /etc/group | grep plugdev
plugdev:x:46:itachi
root@konoha:~#

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

IMG: Fastboot mode

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.

  • Do you need to add udev usb rule for yureka? – moonbutt74 Aug 15 '15 at 19:17
  • @moonbutt74 I've already added the udev rules file from android website, and that contained the yureka's vendorid. Please see the pasted content. The Bus 001 Device 004: ID 05c6:9039 Qualcomm, Inc. is the Yureka device and the vendor id "05c6" is present in the rules file – Kenpachi Aug 15 '15 at 19:22
  • Kenpachi, it may be that you are not in fastboot mode, meaning ' adb reboot bootloder ' hasn't actually put you in fastboot mode. i don't know what model you actually have but follow the guide here concerning booting the device into fastboot mode then check your read again, http://forum.xda-developers.com/yureka/orig-development/recovery-cwm-based-recovery-v6-0-5-1-t3001339 – moonbutt74 Aug 15 '15 at 19:42
  • @moonbutt74 To unlock the bootloader, I must gain access to fastboot. BTW I get the Fastboot screen, but fastboot devices does not list the device – Kenpachi Aug 15 '15 at 19:49
  • hmm okay take a look at this -- adb-fastboot-install https://code.google.com/p/adb-fastboot-install/ Still not sure if it's the device or linux – moonbutt74 Aug 15 '15 at 20:01
  • In the recommended ways to boot the yureka into fastboot mode, abd reboot bootloader is not among them, Method 1 is enable developer options and enable advanced reboot options, plug in phone to pc and then select bootloader from the reboot menu, and Method B is outline in the XDA link. The only thing i can see is a duplicate group entry in your rules. Is that correct? – moonbutt74 Aug 15 '15 at 20:15
  • @moonbutt74 I tried that method as well. Held the Volume up button after connecting it to the PC, I get the same screen as when using adb reboot bootloader. Then tried using fastboot devices. No change there as well. – Kenpachi Aug 17 '15 at 03:11
  • can you run chmod a+r on 51-android.rules and then run fastboot again? all the information i can find is for windows, with one linux suggestion to update fastboot. Are your sure your vendor id is correct? – moonbutt74 Aug 17 '15 at 04:09

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

Try this command for Yu Yureka

sudo fastboot -i 0x17ef devices
