I have rooted Lenovo Vibe K5 and i had installed CM 13 (Marshmallow) it was working good cause of some need, i had to install CM 12.1 (Lollipop) and i tried installing through TWRP recovery CM 12.1, I wiped Dalvik , Cache and System and installed CM 12.1 successfully and ask to reboot system and i clicked on reboot and after that it didn’t turned on , not even in recovery mode by pressing and holding Volume + and Power button. Then i tried to flash it again with pc but its not showing in CMD as well, it shows the error Device not found in CMD and in windows notification it shows USB Device not recognized. Big Mess . HELP
