Urgent! The device failed to update and it's not charging

Hi,

yesterday I tried to make a software repair to my xperia z1 using xperia companion program but it failed because the battery ran out, when I power up the device a sony screen appears then a massage says "software update failed. make sure that your phone is connected to the computer and try again"

The problem is if the charger is not in the phone won't power up but when I plug the charger in a red led lights for 1 second then boots showing the sony screen and that massage then shuts down and it's still doing that like a cycle. Is the phone is charging or not? and how to solve this?
