      Description

      The issue is fixed by looking for data located at 0x0027ffd4, where the backdoor bits are. The right value should be FFFFFFF6

      Translate to the ihex image to upload:

      1. First is to looking for string: :020000040027D3
      2. then the next line should look like the following: :0CFFD400FFFFFFF600000000000020000E
