HTC Desire 500 flashing light and won`t turn on

AC Question

Hello,

my HTC start to act weird so I did factory reset. After a few day Sense start to act weird again so I did reset again.
After few day of trouble I decided to install James rom, but my phone was not rooted. So I start to do that from Desire 500 root manual from this forum, but my phone turn off and now I can`t turn it on.
When charger is conected there is orange blinking light, like battery is drained out and I try to leave phone for all night and day on charger and nothing. Then I remove batery and charge it with shock charger in service shop. When I put battery back, all is the same. There is no way to get into fastboo. Can I do something and what to make my phone work?
