[Q] Unable to bootafter aborted lollipop update. (moto g 1068 DS) topic

Hi,

After getting the lollipop update notice, i downloaded and tried installing the same. But after reboot at about 2/3rd installation of new system it aborted with no error at an icon with dead android. This icon persisted for a long time and i rebooted the mobile. Now it is stuck at "powered by android" message with no progress.

I have tried so far:
- vol down button and power: Recover option. This gave me no command error.
- vol up button and power: delete /data and /cache. The mobile automatically rebooted and is stuck at the same message - "powered by android"

How I can recover my mobile? either to stock 4.4.4 or 5.0
My cell is stock 4.4.4, dual sim 1068 (Indian version)

Thanks for any help..
