is the tutorial for how to downgrade these chips released? no way would anyone actually MAIL and pay this idiot to flash the chip.
I have a lime s 2.5j on the santa FW 2.4.26, where the old posted enable codes no longer work. Looking for a way to use an arduino MEGA to send enable codes directly to the motor controller.
Hi, did you find a solution for DIY downgrade? Thank you in advance

Hi.
Does anyone have the old firmware for the Lime 2.5? The newer firmware doesn't accept the serial commands. The chip is MKE02z64. If somebody has it please share. Thank you!

Good luck getting the old firmware to downgrade so the old hack works and to flash the chip with the firmware you need a Raspberry Pi Zero and a custom modded software.
