H2215 Blutooth Radio failed to turn on

The problem was in the HP ProtectTools security aplication. After disable the aplication and do a hard reset the bluetooth works. I had see that after the hard reset begins a process where some HP software are installed again. One of these software is the Broadcom driver of the Wifi/BT (You can see it for two seconds in the top bar). I think that the ProtectTools blocks some file upgrade (DLL, Exe, config file, etc.) that causes the problem. After solve the problem I have restored a full system backup done before disable the ProtectTools and do the hard reset, and all still works fine. I hope this can help you.
