My yu Yureka is bricked now I tried installing nougat with cm-14 but there is a error being displayed while installing cm 14 (comparing tz version)? error 7 looks like the both the firmware's are not compatible(googled). now the only solution available online was to flash with twrp recovery which needed the phone to start which is not possible for me. 
P.S  currently i have installed  CWM recovery
i  have attached a picture or the error.

so is there any other easier solution to this problem?
can you please also mention the steps?
thanks
