It seems your flash is burned with wrong firmware , did you install TP-LINK official firmware, not a DDWRT? You can try to hold the reset button on the rear panel for 10s to reset it, but I am not sure if it will work

hi
i installed dd-wrt on wr841nd v9.3 that dont work fit. i now want to reset factory firmware on the router. how do i it?

please guide me...thanks

If you cannot access the router setup to install a different firmware, you're screwed. Open a support ticket with tp-link and ask if there is a way to revert to a firmware version that "may be" stored in the router. If not, you'll need to buy a new router and use your current bricked router for something else such as a door stop or target practice. Installing dd-wrt voids any warranty that might be applicable.
