Asus wl500gp - how to reset settings?

Question

ASUS

It seems like a stupid question, but for 2 hours I've been uploading different firmware and into none ..
The problem is that at night someone changed the password for accessing the router.
The reset button doesn't work.
Through tftp I fill it with dd-wrt / olega .. The firmware gets up normally, but the settings do not go astray. And, accordingly, it is impossible to go to the router.
Maybe there is some firmware that will overwrite everything?
I tried 4 different ddwrt and from Oleg. Sense 0. All settings are saved after flashing.

Answer 1

After uploading the firmware, you also need to reset it with the Reset button.
Have you tried 30/30/30?
