Phone is in bootloop but fastboot and download mode are openable

[AC Question]

My phone is in bootloop and when i boot into reecovery mode it boots into fastboot mode. What can i do ?-- device name-yu yunique (yu4711).
I have not turned usb debugging or bootloader or oem before flashing cm12.1. I installed cm12.1 with c-apps only.
I can open fastboot mode and download mode.
It is very urgent for my work.

Go into download mode and flash the stock ROM. Evidently there's something wrong with your CM download, it's for the wrong model phone or your phone variant just won't work with CM.
