lumia 720 windows 10 build 10166 dead

My lumia 720 has windows 10 build 10166 installed. Suddenly it has stopped responding - no lights, buttons don't work, doesn't vibrate when put in charging.

I cant unlock, restart, do soft reset.

I tried connecting to my pc and do a rollback with windows phone recovery tool. It detects lumia 720 but is stuck at reading phone information. sometimes it shows error"product code is empty".

Please help.
