Is there any way to back up the certs and keys, besides pulling the eMMC and doing a raw copy? From all I've read so far, that is the only irreplaceable loss if the MCU1 dies completely.
You can install our site as a web app on your iOS device by utilizing the Add to Home Screen feature in Safari. Please see this thread for more details on this.
Note: This feature may not be available in some browsers.
Yes, other topic show how this is done and this Youtube video:Is there any way to back up the certs and keys, besides pulling the eMMC and doing a raw copy? From all I've read so far, that is the only irreplaceable loss if the MCU1 dies completely.
MCU1 does what it needs to do. Sluggish MCU1 is typically a worn out eMMC, new chips perform much better than worn out ones.
All current storage will fail, some before expected lifetime, some after.
MCU2 uses the same screens, They also yellow, I have not seen a bubbling one yet. MCU2 is faster, and eventually they will also fail, we've actually already seen a very very small number fail. And yes it was the eMMC.
As long as you're cool losing AM (in older S), FM, and XM. Sure thing!MCU1 isn’t terrible but MCU2 is sooooo much faster and just keeps getting better. MCU1 is very much legacy mode at Tesla and all we can hope is it doesn’t get less and less stable with each release.
Someone here was offering to do it remotely for a modest fee.Is there any way to back up the certs and keys, besides pulling the eMMC and doing a raw copy? From all I've read so far, that is the only irreplaceable loss if the MCU1 dies completely.
I don't get it. Your screen hasn't yellowed, neither has the one on my 2015. What's up with that?I have a 2013 with 62k miles and MCU1. I don't see any yellowing. I don't notice any lagging except sometimes with the volume button. I don't use the browser and don't see a need to yet. Everything works pretty smoothly including the navigation. I use the USB for music. I like the Radio feature. I don't play any games on it. I can't imagine doing the upgrade for $2500 if nothing I see is wrong. If it goes bad, I would consider it. But I also would probably go the replace the chip route if it was way cheaper.
My MCU2 failed after 2 months of ownership on my model 3 midrange last year. It was replaced.
@Altres, Horrid failure rate? How do you know how large the failure rate is? What qualifies as horrid?
Is the stupid USB music interface different between MCU1 and MCU2? Or is it the same stupid USB Music interface?
He's right, though. Maybe "is or will soon be" would be better but all the MCU1s are condemned to an early death due to excessive logging wearing out the EMMC. @verygreen told me this himself, while sitting in my car discussing the issue, and I'll take that guy's word for it.Failure rate is 100%? Okay, I am leaving your conversation now, you have hurt your own argument.
Technically the failure rate of anything is eventually 100% and the mortality rate of the human race is also 100%Failure rate is 100%? Okay, I am leaving your conversation now, you have hurt your own argument.
Are you sure about that? I'm 74 and feel like I could live forever.Technically the failure rate of anything is eventually 100% and the mortality rate of the human race is also 100%
