Lime SJ2.5 Controller Downgrade service (US Only) (Must have MKE02z64 chip ONLY)

The Lime controller for the SJ2.5 that has the MKE02z64 chip (any model of it) can be downgraded to old unpatched firmware so it can be used with the old arduino/bluetooth hack. This method is out there and uses open source software and a raspberry pi but not everyone can use command/terminal in linux ( firmware is property of the maker so I will not share it). Again this is only for the MKE02z64 chip and I'm putting a pic to show you what to remove the potting to find out if you have the right model. You pay shipping to send it to me ( Small Priority Mail Box is cheap) $30 to cover flash and return shipping. And I'd like to state again US Only.



Image Use something safe like plastic tools ( I used a plastic knife and plastic fork tooth) I'm and not responsible if you mess up your controller! Some controllers may have a connecter already on the pinouts.

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.
