There a subtle differences with Meridian units: DSP speakers, Processors, Spinners, � and also the age of the unit can make a difference.

So the best generic advice is to power cycle when prompted to during the update process. Then Power cycle post upload.

If is a DSP speaker; I always reconfigure afterwards.
If is a processor; I always re-type and re-load the configuration using MConfig.

For some units it is overkill, but this is what I do and I don�t have an issues.
