Spice Dream UNO - Bricked - Doesn't goes into Recovery and Fastboot.

Hey guys!
Just been flashing some various roms yesterday like RR, CM, PAC, etc etc.
It is rooted and has an unlocked bootloader (unlocked with fastboot oem unlock command).
Today, I just wanted to restore a CM12 compressed backup which I backed up on TWRP. Total size was 13MB. Restored in 2 secs.
I left it on charge for few hours like 6-7 hours. I tried to turn it on but screen backlit just flashes.
It went into bootloader, tried entering recovery and fastboot but it refused to go inside.
What to do? How to unbrick? Main thing is that it doesnt even goes into recovery and fastboot.
