XH540-W270 chose wrong model to recovery moter

XH540-W270

Issue Description

When I recovery the motors, I made a mistake to choose wrong model. The error is Bootloader Failed. Now, I can not Scan anything with the Dynamixel Wizard2.0. Can I have methods to fix the motors?
sincerely!!

I did that too once. You just need to reuse Dynamixel Wizard again to recover its firmware but this time choose the correct Dynamixel. But let the DW scan all possible baud rates at the start.

I operate in wrong steps, first should recovery the motors in true style, then scan all the baud rate with DW.Thanks for your advice!
