Couldn't you just roll it back to build 19203? The dealership would never know you rolled it back.

Maybe, but since 3.4 is an unofficial version who knows.

Just installed 20021 on my '16 w/Nav. Only issue I had was that the system never rebooted during the reformat tool. At the 15 minute mark, I ended up just pulling the thumbdrive. That forced the reboot (after the screen turning into a rainbow of colors.) Stuck the other thumbdrive in, and 28 minutes later, complete!
Did a master reset to wipe out any misconfigs, and so far so good. Surprisingly, it even feels a little more responsive than on my wife's 2020 Explorer.

I'm non-nav...so I don't have to deal with the map stuff thankfully.

So I have read through this thread completely and still have some questions on what all is needed to update from 3.0 to 3.4. I have a 2016 GT350 with Sync 3 version 3.0 and NAV. I have already upgraded to the CarPlay USB and have also upgraded to the 2018+ satellite radio antenna (probably irrelevant here). Also, I have never done any FORScan mods to the car. Are there any other hardware, software, or firmware updates that I would need to do before attempting to upgrade to 3.4 to get the full benefit? I have no plans on ever updating to the digital dash, but are there any other hardware upgrades I could get (even if not required) to improve the system or provide additional functionality with 3.4? Finally, after the 3.4 upgrade, will the Shelby boot screen still be the default or will have I to use FORScan to put that back?

Cannot answer about the splash screen but as far as the 3.0 to 3.4 update everything you need to know is on the Cyanlabs website. They can also answer any questions you have. Ut's there software so dealing with them directly is your best bet.

When you say “master reset”, you mean... what, exactly? Is that the “Power+Seek” combo, or something else (like Reset in Settings)?

I do not think so put since I have not done this update I'll let someone who has chime in.
