    1. select the instruction you need to change in "IDA View" subview. enter image description here

    2. switch to "Hex View" subview. You will see several highlighting hex numbers. enter image description here

    3. press "F2", edit it, when you finish, press "F2" again. enter image description here

    4. That's all. you will see your change in other subviews. enter image description here
