P1i not starting up, only light flashing on switch on

Hi All,
I have a P1i bought in India. This phone turned brick a few days ago after I "Switch Off" one evening. I tried updating the CDA version using XS++ and flash with Generic World2 software. The S/W versions are

Phone smartphone version: R1C01
Phone software version: CXC162037 R9G007
Processing Unit: CXC162175 R2A03
Organizer: CXC162108 R6D23
CDA: CDA162022/2 R6D22

Is there anyone who can help me by steps or through any site (paid/unpaid) where I can download FLASH S/W & get my phone up and running. Or its better to go to SE repair shop ?
Suggestions most welcome
