To change the value of the integer variable maxusers from its current value to 0x200, do the following:
# adb -kw physmem f7c6 maxusers/D maxusers: maxusers: 495 maxusers/W 200 maxusers: 0x1ef = 0x200 $q |
Replace maxusers with the actual address of the item to be changed as well as the value the variable is to be set to.
