READ THIS FIRST!

Due to changes in EC4.0 and EC5.0, do NOT downgrade firmware from EC 5.0 or later directly to EC 4.0 based code.  The code levels would look something like LW40.xx.P440.  Basically, anything that conforms to the following pattern: LW40.XX.P4xx.  This will cause a non-clearable 900 Service error. You will need to contact the TSC for instructions on how to clear this error.

This includes installing a DLE with EC 4.0 code into a device that currently has EC 5.0 or later code.

Code levels earlier than EC4.0 can be sent to EC5 level devices without causing a service error.  

To downgrade EC6 code to an EC4.0 level, you must first load an EC4.1 based code.  This would follow the pattern LW41.XX.P4xx.  Once the device is at an EC4.1 level, EC4.0 code can be sent.  

According to the firmware FAQ posted on our support site, we do not officially support downgrading firmware.  This is the reason we do not support it, even though we go to great efforts to prevent these kinds of events from happening, sometimes it is unavoidable.  We are sorry for the inconvenience.
