There's not much we can do. Those devices constantly query the ECU and interfere with the flash process. They will interfere with any tuning solution you decide to use. You don't need to completely remove them. Just disconnect them from power or from the CAN bus for 1 hour while you reflash the ECU.

Then you probably have some other device connected to the CAN bus or the OBD-II port of the vehicle. Gauges, loggers, alarms, modules that keep the lights or radio on. Common culprits are devices made by MX-5 Things.
You will need to disconnect them temporarily while you are reflashing the ECU.

What car do you have? Do you currently have an aftermarket tune on the ECU? Does it fail right away or somewhere in the middle?

This error can mean one of two things: 1. The ECU is stuck in some weird state after the last reflash. Try disconnecting the battery for a few minutes to reset it and then try again. 2. The ECU was tuned previously with a tuning solution that locks it on a deep level. It has not been tuned with Vers...

You can try.

It will not. EcuTek locks the ECU on many levels and needs to be removed before any other tuning solution can be installed. Try contacting the company that originally tuned the ECU or a Mazda MX-5 tuning specialist, such as Fab9 Tuning.
