Follow up to this issue: after multiple attempts, it became clear that timing the initial process is crucial. Once we timed it right and got the flashing lights, we were able to upload the firmware successfully. Thanks for the reply!

While performing the first few steps to convert an Epson P400 to the chipless firmware (the first upload test, to determine if the printer will work) it keeps getting stuck at 55%. What could be causing the test to hang at this point, consistently?
