Downgrade

• The listed versions indicate the necessary intermediate steps:
  • 5.11 -> 4.95 -> 4.71 -> 4.57 -> lower than 4.57
• Note: Always use the higher level GUI version in each step.
• For example, say you are downgrading from 5.11 to 4.53
  • using the 5.11 GUI, downgrade to 4.95
  • using the 4.95 GUI, downgrade to 4.71
  • using the 4.71 GUI, downgrade to 4.57
  • using the 4.57 GUI, downgrade to 4.53
