How can you upgrade with total loss of any previous installations and configurations?
To be more precise, how can you flash a router already running on an OpenWrt firmware with a new OpenWrt firmware and make sure that the flashing wipes out any previous installations and configurations?
The new firmware may be either:
- a later version of downloaded sysupgrade bin file or
- a custom image you might have created.
I can thinks of a two-step process:
- Follow one of the "factory reset" procedures in this Wiki:
- Apply the new OpenWrt firmware.
My question would be whether there is a one-step process (i.e. without step 1 above) that wipes out previous tweaking.
From the following Documentation, it would appear that the default result of flashing a new firmware (without taking specific care to either preserve or wipe out anything) is the preservation of some configurations:
(I intended to put this post only in "Installing and Using OpenWrt." Somehow it got tagged for "Nework and Wireless Configruation," and I don't know how to remove that. Sorry.)
