    Hi Everyone

    I have a Nov 2017 MS and being now 2 years into the 4 year life span of my eMMC, I'd like to just repair it now instead of getting stranded and paying Tesla crazy money for another MCU.

    I've separately messaged wk057 and ingineer but never received a response. Is someone able to recommend anyone else that does these repairs?

    Thanks!

    I wish all these repairs would just solder an EMMC HOLDER so in the future you can just slide in a new eMMC rather than take everything apart.

    Hi, you can bring/send your car up, send me the Terga, or I can even have someone come to SD and do this at your house for an extra charge. Turn around is about 1 week. PM me for more details. Helped a few forum members already.

    A socket is not as reliable. Our fixes last 20-a few thousand years. If you send us your Terga, we can send it back with your data copied onto a new eMMC soldered onto your board.

    WK057 does in the East. Very few people offer this in the world currently. The process is not totally safe for everyone to attempt. Killing the eMMC before the data is recovered leaves a really nice bricked mcu needing to be replaced by Tesla. Not doing this right can kill the eMMC prematurely. At this point in time I suggest you work with someone who does this and has a solid process.

    If someone sends us a Terga that cant be recovered fully, we offer additional solutions or we don't charge anything other then the shipping back.

    ingineer used to do it in SFO area, but heard he recently has not been responding so I didn't include him on the list. But my info is hear say, and I have not contacted him. Nor do I currently have any reason to.

    eMMC Repair/Upgrade for Model S and X you can either ship us your MCU or it can be done through service at The Electrified Garage.

    I’m tempted into a fix, even preventive, but what is Tesla’s word on this when in trouble aftersards? Any guarantee will be void?

    Ditto. I’d imagine it may be best to wait until warranty is over and then do this, just to avoid any issues.

    Yes I definitely wouldn’t touch it while under warranty....what’s the point?

    Is your car's language set for English? If not, you best check with Chris at EV Tuning before going any further. Don't know if he can do other language.

    You do know, right? that Elon says they are working on an upgrade path from MCU1 to MCU2? They are having trouble. He says its not easy. (The guy that is building a rocket to Mars says it isn't easy.) He says it will cost about $2,000. About. No idea when. Even when, it could take years to get through the cars that are out there in the fleet already.

    The latest sw (2019.40.x) writes less to the eMMC, so hopefully that will help too.

    Pray tell, you do you know that? I hope you are correct, but where did you hear that?

    It's possible to proactively retrieve the critical data from the MCU before it fails without the risk of desoldering the eMMC.

    It requires MCU removal and disassembly, however. And some familiarity with Linux.

    I saw a posting on TMC from ingineer. He lost his lease on the property that he had been in since forever. He had to move. He even talked about it was going to take a while to get set back up. I guess he is not setup yet.

    Im assuming this is the tweet you’re referring to?

    Elon Musk on Twitter

    If so, that’s regarding AP2.0 -> FSD APE upgrade, not MCU1 -> MCU2 upgrade. From work by @verygreen, the latter sounds relatively straightforward.

    No, not that tweet.. I am not a tweeter, (Is that the correct term?). Another. Saw it weeks ago, but don't remember its date. There's one like it on the feed you linked to. But 18 Dec.
