Lenovo A6000 not entering recovery mode

[AC Question]

I have rooted the devise using Android ADB mode. After that I installed Cyanogenmod 11 built for Lenovo A6000. The Operating system also had superuser installed. I am using TWRP Recovery mode. Due to flashing a corrupted MIUI6 OS on my device the mobile has stopped working. Currently there is no OS present on the ROM of the device. The best part is I have Backed up the Stock ROM and also the Cyanogenmod ROM. But I am having difficulties restoring the backup as the device won't enter the recovery mode. I have tried ADB commands and Fastboot commands with Minimal ADB and Fastboot. Please help
