Router: Netgear WNDR3400V3
It had dd-wrt for a long time - about 10 years. However, recently I tried to use it as a repeater which I couldn't get it to work. Hence changed firmware to OpenWrt without realizing it doesn't support my router's wifi.
This is when I tried to get dd-wrt back by installing a beta mini, but then I can not connect to it.

Hoping that it is not bricked, are there any path available to get it back?

TIA

This wiki probably needs some editing, but:

https://wiki.dd-wrt.com/wiki/index.php/Netgear_WNDR3400

There is also the old and current OpenWRT Wikis:

You may also be able to use nmrpflash to de-brick:
