Quoted from eharan:
You should be good. I spoke with CGC and they confirmed that if it says 3.0, you are good. They said it is timing out in the closure process but the full code is there.
eharan Thank you for posting this ... seems like it could be a common issue then and I wish I read this before I did any more dinking around with my mods for this machine. Interestingly enough, my game retained all the high scores.
In the box with the topper RGB control board I found this:
So I gave it a go and saw that its v3.0Beta3 but the install also froze at 81% just like all the rest. I'm fairly certain you really don't need a class 10 MicroSD as the main difference between them is WRITE speed, the class 10, 6, and 2 Micro SD cards all had roughly the same install speeds, and all gave me the same results.
UPDATE: It looks like both the RPG GI lighting upgrade AND the Topper upgrade kits come with a MicroSD card with firmware v3.00 on it, and its mentioned in the installation guide that its required for installation. It appears the ONLY upgrade kit that doesn't come with the MicroSD card and has no mention that you need to upgrade firmware is the HD display/Sound upgrade, which unfortunately for me is the one I started with.
