GM N25-250336 update

[leres]

When I stopped to fill up, returning from a mini-road-trip, I was offered the N25-250336 update. When I got home I tried to install it. It estimates 15 minutes but fails with 13 minutes to go. I've tried several more times with the same results. In other threads I see people say to take the car off of wifi networks so I removed my home network -- no help. I also tried rebooting (hold phone hangup steering wheel control for ~20 seconds -- until screen goes blank) before an attempt -- no help. I also tried putting my iphone into airplane mode to prevent it from connecting via bluetooth or wifi.

My take is that it has already downloaded the update in the "background" because it says it's verifying the update. I suppose it could be checking a checksum/signature against an internet server that is overloaded/down.

I dunno, this all seems pretty weak to me. (Hopefully the update contains fixes for the updating process!)

If you can leave your car outside overnight, the update should complete it's download if it's not complete already.

There's nothing but sky above the tar and gravel roof over my garage. It gets a decent cell signal. Also, I don't think it would be offering to update if it hadn't already finished downloading.

I had the exact same problem installing the update. It failed at 13 minutes left every time. I've also tried everything mentioned by others to get it to install with no luck.

Now the option is grayed out and it just says it failed and to contact the dealer. I can't seem to get the car to prompt me to install it now.
