To be able to update any firmware or software, one must be able to log onto mother orange, unless one has a copy of the required file, and knows exactly what file they require.
Its a darn chainsaw, go out and cut wood, most/the majority of saws will never require a software update.
All regular and normal troubleshooting procedures apply to AT saws which automatically cover the vast amount of issues/repairs.
But there are the "well we changed the computer thingsy and that other doo-dad, pulled the muffler bearings, swap the piston and cylinder, changed the brake band.......................but wow it was the tank vent all along".
As an end user you can still work on your saw, likewise you can work on your own truck made in the last 20 years.
