Do you know the answer?

To revert, I think all you have to do is to go back to factory settings by a hard reset.

Flashing the firmware overwrites the master copy in the EEPROM. Factory reset merely restores the user configuration to the original state.

Yes, you may replace it as long as you retain the original but you may not modify it; it being someone else's property.

Where does it say it is someone else's property?

Iirc correctly, every router I've ever had recommends resetting to factory defaults after updating the firmware.

In Batboy's world, this would rather defeat the object of the exercise

Every router I've ever had resets to factory defaults when you update the firmware.

You mean it reloads the firmware that was there when you bought it and over-writes the firmware you've just loaded into it?

Remind me not to ask you for a router recommendation...

No, you load the hacked firmware, which resets the router to the factory defaults.

Then you make whatever changes you want.

If you want to revert to the factory defaults, you either do a "long reset" or you load the unhacked firmware.

I've just read though the last 4 pages and not one person has admitted that they didn't know the answer to the OP's question.
I'd love to know the answer as well but most people here seem to just want to give responses in political form.

He's been given the answer by any number of people, what he wants is a link to something in words of one syllable (or less).

And most people have said that there probably isn't one- where something is covered by current legislation or contract requirements then there is no need. Also, as has been admitted, there has yet to be a test case in the courts.
