We did it! we turn off the brain, the battery and even delette all programs on the brain and upload again and the same error happened 
Could you post your code? Most likely a code issue.
I found the solution, to error 03802010 don’t put variables, motors or sensors that you don’t need it or that aren’t connected upload your program again and that’s it! 
Well, the memory protection error is caused by something incorrect in your code, the number is sort of irrelevant (it’s the memory address in your code where the problem occurred). It doesn’t really have anything to do with unused variables etc. One common problem is using Brain.ThreeWirePort in different cpp file to where Brain was defined. The mistake is accessing an instance of Brain that may not have been instantiated yet.
