I cannot seem to override the lock code in flash. I have entered the data shown in the memory view for adds. 0x200000 to 0x20001a and tried to unlock, but it did not work. I tried to lock and unlock - no luck. I tried to load code into all but sector N, but still no success. Here is the error output:
