Sony Update Engine Failure (error 100)

[RonanN1]

Hello.

I got a message to update my phone software, when I conected my phone to my pc, and after I started the process i got the Sony Update Engine Failure (error 100) message. Now I CAN'T USE MY PHONE. Every time I start it i get the message:

the software update failed make sure that your phone is connected to the computer and try again

What now?

And please don't tell me to delete/restore my phone because i'm not gonna do that. I have important data on that phone and I'm not gonna delet it just because you can't make something work ok.

Thanks.

I experienced a similar problem myself when I tried a re-stor/repair earlier. I un-installed PC companion and re-installed - same problem!! Then I un-installed using REVO un-installer(Free) to be sure I got rid of all remnants before re-installing again. Then no more problems. My internet line is not of the best, and looses connection from time to time. If loosing connection in the middle of a download, this might unfortunately happen. On my PC even the WIN 10 download was faster than the PC Companion (repair) download for some unknown reason? The PC Companion system files took about 6 hours to get!!
