I already did it with all the content. first to save the old emmc data sudo ddrescue / dev / sde backuptesla.img So far without problems. after to record the new emmc sudo dd if = / media / sda2 / backuptesla.img of = dev / sde sde is the emmc. sda2 is the hard drive. the new emmc is apparently recorded but it does not work in the car, I tried three emmc and always the same result
I find it very hard to believe that the SC has the ability to tell how close to failure the eMMC is, I suspect they were either confused and telling you some other stat or they were outright making that up.
They do have a wear indicator in their diagnostic screens, but I don't know how accurate to actual failure it is. (I think it is based on the rated write cycles.)
Hmm.. so a service center can look at the eMMC in my car and tell me how much capacity is left in it? Good to know if true. Thanks! Oliver Barrett
When I took my car in for the annual maintenance, I asked and one of the SC people to check the eMMC and said that it still looked healthy. When I picked up my car, I asked again but this time I asked the percentage left and they said 81% so I got the information from 2 different Tesla people.
Hi I think I know what happens to me I think p1 p2 and p4 are not correct. p3 I can mount the image without problems. p1 p2 and p4 linux says error in file and p4 does not identify the ext. Does anyone have these correct partitions? can you send me by pm someone please? It is a Tesla Model S 85. European December 2013 (nl)
Just had my preventive eMMC replacement completed by TonyT this past week and want to give him a big thumbs up here. Turns out we live very close to each other so he did all the MCU removal and re-fitting work as well, making it a one stop shop for me. I was concerned about damage to the fragile metal interior trim and he made sure he took every precaution to prevent that from happening. Any time I texted him with concerns, he would respond promptly. Anyway, just wanted to vouch for his top notch work publicly. He is a fellow Tesla owner and enthusiast who happens to be a whiz and nice guy to boot. (pic of my sexy new module attached)
Nice. He’s working on mine now (at least he will be as soon as it arrives tomorrow). It’s good to hear you are happy with his work. I’ve had a lot of questions and he’s been really responsive. My only issue is I live across the country and I have to get by with a crippled car. I can’t charge beyond 41 miles so it really limits my options this week. Fortunately I have a car to borrow as of Tuesday. Disassembling the dash was straightforward but time consuming (for a first-timer). It should go back together pretty quickly; much easier to push clips in than take them out.
I'm not a tech guy so I'm not sure if the chip info is important to keep private or not. So I hid it just in case, figured it was not relevant so why not. FYI for those interested in doing this, turn off scheduled charging and set the charge limit to 100% beforehand. I had mine set at 95% and was able to supercharge to that number without any issues (but no further). You won't have AC and the car charging outlet won't work (cigarette adapter). I don't know if turning on the fog lights beforehand would have kept them in that setting but I wish I had since I had some bad weather days too.
11:45 AM · Dec 30, 2019·Twitter Web App Jason Hughes @wk057 Looks like @elonmusk followed through, and excess logging to the eMMC has been significantly curtailed in recent versions. Should extend life a bit on MCU1. Bit (like, years) late for many vehicles, unfortunately. Many will still need repair eventually. Quote Tweet Elon Musk on Twitter Elon Musk @elonmusk · Oct 12 Replying to @wk057 and @tesla Should be much better at this point
Hi I do not know. that same day before dying the mcu was updated to v10. For some reason, the only thing I could save without any mistake was p3. The other three partitions I have a multitude of mistakes that I or one more expert person that I can save.
And if you look at the Tesla app on your phone and scroll down to the bottom, does it still mention there the firmware version on the car?
