Are you just being a troll for a laugh, or do you not read the replies, or do you not understand the replies? You clearly have "wires" as you have been using a pump!!, a relay!, a DHT and an LCD. I am hoping (2) and (3), but (1) seems close.
You have been given exact instructions. Here is a video showing what you will be seeing and doing, from the instructions in Post #24. Start the video at 2:10.
That won't work because you must be able to upload the "ArduinoISP" sketch to the programmer board:
You must have a functional Arduino board to use as the programmer board.
I think it is a good idea. You will need a functional board if you want to try to use a "Burn Bootloader" operation to recover your boards. As I warned you, there is no guarantee that the "Burn Bootloader" operation would recover the boards after all. More likely they have suffered permanent physical damage.
And even if you do manage to eventually recover the two boards, the Nano is a very nice board and so I'm sure you will find a use for all three of them eventually!
