YU Yureka Plus Cyanogen installation

I bought YU Yureka Plus with KitKat..but I want Cyanogen OS in my yureka plus.. I found cyanogen OS in XDA site.. There the procedure is also described I think.. Is it OK if I do according to the instructions.. Or is there any risk..

I need stock andriod 4.4.2 for my old Yureka Plus Yu5510 mobile

When i installed Yu5510A firmware my device Yu5510 it is not switching on ....

Unable to flash any roms on my YU Yureka

I have tried installing various roms on my yu yureka after it suddenly stopped working. While using the phone normally it got switched off and on restarting a loop on "YU" logo showed then it turned off then logo again........ The first coming into to my mind was that somehow this phone has got soft bricked and so I tried flashing cm12 official 5.1 lollipop on it and it failed. Since then I have tried various roms given on xda with the correct steps but am unable to flash any of it. I have tried installing 9 roms since then and supposing that after so many tries what is it am missing or something really wrong with my phone. plzzzzzzz help
