Just re read stuff and it looks like y'all are correct, the update doesn't update the if coil and still works.
For things that do need update do I go through the process from 4.1 to the next 3 or however many updates?
You can load any version right offf the bat. No need to update with each one progressively.
Some examples.
You can load 5.2 and use all coils.
You can load version 4 and use all coils except x35 coils.
You can load version 2 and 3.2 and use all LF coils,,,no Hf or x35 coils.
You need to have your coils, remote and headphone module(s) near your computer when updating.
One word of caution.
Do NOT ever have more than one headphone module turned on at the same time when updating.
I have had Deus for 5 plus years and am very familiar with the updates and operation of Deus.
Don’t confuse Deus with the newer released Xp ORX. As there are some differences when talking about coil compatibility and headphone modules.
