It is important to obtain the correct upgrade file/firmware  for your particular model of Yu phone. The most common way to get your device's software is to download from the manufacture's website, but not every manufacture publish these files. Your other chance to get the firmware is to find it on the internet. There are a few websites, where you can get yours.

  2. Turn off the phone completely.
  3. Press and hold both Volume UP + power on the phone. After the screen lights up and Yu Yunicorn LOGO shows on the screen release the power but keep press the Volume UP until the recovery menu displays.
