BB Flash issue

Car : European 335i E91 08/2008
ECU :IJE0S

I used bb flash and bavarian cable in order to backup the ecu
Done after 1 hour

File patched with fuel table

Write the file and after 18 min (the end of step 3 ) this error appears :

FlashModel.Flash ECU Programming state = 0x06 Bad DAF/Map section. ECU will need to be written with a known good file

Any idea ?
