Hard Bricked Lenovo S90 U

I had a Lenovo S90 u on kitkat so I decided on installing the lollipop update. After successfully unlocking the bootloader and installing the 5.0 update, I found out that it did not have google apps. I decided on rooting it and installing the google apps but it wasn't rooting, so I thought maybe the bootloader needs to be unlocked again. I accidently flashed the kitkat unlock bootloader file through QFIL and now the phone only vibrates after every 5 secs. I've tried disconnecting the battery, pressing the buttons, but the computer doesn't recognise the phone.

I got the lollipop ROM from needrom

What can I do? Your help is greatly appreciated!
