We have updated successfully 2 of 3 servos from firmware version 25 to 27. For the last servo the firmware update was not working. Now also the R+ Manager does not find the servo any more. Firmware recovery is also not working as documented.
Please advice what else can be done or, if we need to get a replacement/repair. All 3 dynamixels are brand new.
We apologize for your inconvenience with our product.
It sounds like the communication IC is troublesome, however, in order for me to decide whether the product needs to be repaired or not, I need to collect little bit more information.
