[Romualdo]

I install gargoyle_1.10.0-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin but i want to go back to my original firmware in my TL-WR740N Ver. 4.21. Anyone can tell me how i go back to the original firmware without bricking it or any problem?

It should be enough to update the firmware via the GUI.
