A2-DB3150 Flashing

[riders4sia]

Right here is my predicament I have a friends k850 and it has died here are the symtoms

1.turns on ok and keyboard lights up and camera blue led lights up and thats all it does.

2.when i try to connect it to a2Uploader by pulling out battery and putting back in then holding C button and connecting cable it does nothing cant even identify the rom etc, all that happens is the red led next to the power button strobes constantly.

Whats wrong with the bloody thing?

I havent tried flashing it yet with A2 because i figure if it cant even identify it then it wont flash,also i am not sure what main/fs/custom pack to get?

It was on o2 UK, i have tried doing a re-flash via sonys update program but that does not detect it either.

Any suggestions?

Thanks people for your help

check with a fully charged battery and post result
