Firmware flashing fails: stk500v2_command(): command failed & verification error; content mismatch
I changed some parameters in the firmware for the i3 MK2S but it won't flash to the printer. Below the avrdude output log:

avrdude done. Thank you.
I used the Arduino IDE environment with RAMBo board selected and Slic3r to flash the FW. Hope someone knows how to resolve this. thanks!
