I have 20thumb drive via 16 focus eco boost, did recomended upgrade via memory stick no system completely dead all fuses etc ok any ideas
 

sorry about wrong words

So when you open the door, the screen stays completely black ? And it was fine before the update ? What was the last thing you saw on that screen, before, during or after the (attempted?) update? Did the update even start ?

System has crashed, but you should be able to recover.

1. Disconnect the battery negative lead from the vehicle.
2. Leave it off for 20 minutes.
3. Reconnect the negative lead and WAIT for 5 minutes.
4. Open car and turn on ignition, system should boot back up.

had a mechanic (not electrician) put a diagnostic on & although not auto electric came back with idea that a corrupted file had been downloaded, any suggestions as how to remedy please

Yes, follow my instructions above.

After Unofix's advice go onto Cyanlabs and use their software to install the latest version and see if it comes back

Did you download the file yourself, after being given the link on presentation of your VIN ? Or did you get "a" file from somewhere / some friend? Was it the system update (Sync x.xx ?) or the map update ?

Gentlemen, i want to thank you for your input unfortunately none of the recommendations has worked so have had to bite the bullet & book it in to an auto electricians, thanks again for your invaluable advice

 

Cyanlabs didn't work then?

Dave, completely missed it, will give it a shot, cheers for the reminder 

Follow their instructions to the letter😉

im back, after trying all your very valuable advice to no avail(thank you)took it to auto elec, screen is kaput replacement £300 ish so on the hunt for second hand replacement or change to android system, any advice greatly recieved

That's a shame.

Probably easier to fit a "known working" replacement.

ANOTHER QUESTION, WHERE CAN I FIND GENUINE FOCUS PART NUMBERS??? 

On the back of your module

Cheers dave

Gentlemen, thank you for all the sage advice but im afraid nothing worked so the car has gone in part ex for a new Puma ST line X which i picked up yesterday, once again your advice & suggestions have been invaluable & i wish you all good motoring into the future,
