Hi, I too had the same problem, but tried the below steps to bring it online,
1. Full Wipe (Factory reset, System)
2. Flash Boot image, ZIP file in recovery (TWRP in my case)
3. Wipe Cache, Dalvik Cache
4. Reboot (automatically boots into recovery
5. Tried doing factory reset, but didn't work. Again reboots into recovery
6. Reflashed ZIP file and immediately wiped cache and dalvik,
7. Reboot... Succeed this time.
Hope this may help you mate.
