Seems this guy[0] could do just that if only he had access to a SyncServer S200? The very author of this blog post replied to the person and told them about his interposer solution, he’s not unaware.

Alex’s solution doesn’t patch the module itself, but it patches the FW of the MCU in the SyncServer motherboard that drives the module.
People have looked into patching the module itself, but I haven’t seen any progress on that. It’s possible that the M430 MCU doesn’t allow dumping of the FW that is stored in on-chip flash.
