Rooting nexus 4 failed

I was trying to root my nexus 4 by the following steps:

• Download and copy the file UPDATE-SuperSU-v1.43.zip to /sdcard/


• Download the file CWM 6.0.3.5


• Got into Fastboot/Bootloader Mode on Nexus 4


• Execute the command fastboot flash recovery recovery-clockwork-touch-6.0.3.5-mako.img


• Choose RECOVERY from the Fastboot menu and enter Recovery Mode


• In ClockworkMod recovery “flash zip from SD card”


• Then selected “choose zip from sdcard”


• Now I should see the copied file UPDATE-SuperSU-v1.43.zip but there was none, and I got the output `Can't mount /sdcard/

Then I tried to use Install zip from sideload

• I sent the file with adb sideload UPDATE-SuperSU-v1.43.zip


• 
  

  I get the output:

  
  

  Restarting adbd...
  E:Can't mount /cache/recovery/last_install`
  E:failed to open last_install: Invalid argument

  Setting permissions
  Unmounting /system and /data
  Done
  

Then I go back and choose reboot system now but when booting only the GOOGLE sign pops up and then the X (I was waiting for about an hour)

SOLVED I did a full reset by downloading the original factory image from google here

And then I followed the steps in this tutorial: here
