General :: Xperia X10 Bricked?

I uploaded a custom rom on my xperia x10, for that i unlockd the bootloader and stuff..

Now, my phone is switched off since 15 days, when ever i try to switch it on, it vibrates once and nothing at all afterwards...if i press power button again, it won't vibrate, unless and untill i remove the battery and reinsert it in phone..

i see three red flashes of light, when connected to PC..

1. PC Companion for update, repair and custom repair is not working...most of the time phone is not detected..

2. SE-update service is also not working and phone is shown as Xperia arc..

3. Flashtool, doesn't recognize the handset

4. few, technician told me box flash would work, but again, it didn't work out

Now, i don't know much about this, but i do understand that hardware seems to be good, till now, the only issue is software and that to initial boot process i.e. bootloader.

is there any other way i can upload a new custom rom on my xperia ??
