Why has my phone OS for my BlackBerry Z10 completely wiped out?

I have tried and tried to reload my device software thru Black Berry Link but i have been unsuccessful, can anyone please Help?????????

Can you be a little more specific about what happened?
Which OS were you on?
Any LED responses from the phone during the reload?
