That Koreader method presumes you have access to the root file system, I guess.
IMO, the easiest and safest downgrade route is to use the serial method. You'll need to extract the target firmware with KindleTool, tear your kindle down and you'll also have to buy a serial to usb adapter.
Depending on how you set it up you don't need a soldering iron to get the adapter connected to the board, you could use jumper cables and sticky tape, you won't spend more than $ 10 in materials.
