Do you mean to un-brick a device that way by loading cure firmware? Probably no because usually a bricked device isn't far enough into the boot sequence to look at the card content. You can see in a healthy device that 'Loading maps' appears on the screen before the flash is initiated. Most bricked devices stall or bootloop before that.

Edit: Although on reading your post again I wonder are you referring to executing .txt commands using a modified Boot.bin as an RGN to flash via Updater.exe in preboot? I've not tried that to flash cure firmwares as BIN files but maybe it'd work. See here, Post #33: [Only registered and activated users can see links. ]. Seems little point however because if you can attain preboot you can flash directly.
