When should you run the RMA shim tool on a Chromebook?

Running the RMA shim tool on a Chromebook is specifically necessary when you are replacing the system board. This tool is designed to handle specific tasks related to the RMA (Return Merchandise Authorization) process, particularly ensuring that the new system board correctly integrates with the device and operates as intended. When a system board is replaced, certain configurations and permissions may need to be reset or initialized, which the RMA shim tool facilitates.

Using this tool ensures that any new hardware is properly recognized and that any old configurations are cleared, which is essential for avoiding conflicts that can arise with hardware and software compatibility. Consequently, running the RMA shim tool in this context is critical to ensure a smooth transition when major components like the system board are swapped out.
