Successful data recovery of broken eMMC chip MCU1

Zuikkis · Oct 18, 2020

Anyone have fw 2020.36.3.1 binary?

My emmc is unreadable.. I'm thinking to flash new chip without keys just to get mcu usable again. Is it enough to just format p3&p4, or does it need some files?

I booked a service time for daughter board replacement, but it can take a lot of time until they have the part..

Has anyone tried service with empty emmc, playing dumb "oh it just stopped working". Perhaps they will simply write the keys and charge you for the work?

I heard some people in EU had success getting Tesla to reprovision their MCU's with blank emmc. I cannot find the specific posts, but apparently EU has some laws that force Tesla to do so (for a fee). That might enable you to just bring them your MCU with brand new, but blank emmc (or perhaps empty partitions). Just a thought, I am no expert on Tesla in EU.

You can use this service, you will have to ship the damaged emmc chip: Tesla Model S damaged eMMC / MCU files recovery service, certificates and keys. | eBay

So they might do a better job at pulling the files but they don't generate them. From the listing..."in rare cases we can not recover the needed files (less than 1%)..."

Sure, but it is no cure no pay, so it's worth the try unless Tesla provide the files for less.

Well, the full daughter board replacement is only 400-500eur, that's not too bad. Only downside is the long wait, might be faster to send chip to above service..

But thanks for the tip, now I have more choices.

there is another easy recovery option, but you will no longer be able to use the Tesla app and updates (because the certificates are lost).

amiral_sub · Oct 19, 2020

you can contact Laadkabelwinkel (Nederlands) to see with them how to recover the lost data. But I know that it is a very long process : several weeksof data readings at -20°C

Not anymore, the recovery can be done in room temperature in about an hour. The above is from when Luke sent the emmc to the Polish recovery company.

Still looking for this.. I found 36.11 but it probably needs to match?

At least the active partition must match. I have the 2020.36.3.1, that you can download from me.
You should check the firmware of the other partition, or it might not be able to boot properly.

Everything you need is in the IC

When recovering my emmc, I flashed the same binary image (matching my last firmware) to both partitions and it worked just fine. The only thing that happened was the pre-downloaded update failed (probably because the inactive partition was not a match as I updated it to the the same version as active), but then a subsequent update re-downloaded and worked just fine (and many updates applied successfully since).

I can repair your car cert & key from unreadable eMMC. If you can send me your unreadable eMMC to Ukraine.

What about encryption, afaik emmc data encryptes started from 2020.24 version

emmc data encryptes in MCU2 (Intel). MCU1 (Tegra) data is not encrypted.

Hello everyone.
Tell me what could be the problem? I use a TS-RDF5K card reader. The power supply was set to a voltage of 3.2 volts, 2.8 volts reached the board, and a power of 1.2 amperes.

I have my power supply set to exactly 2.8V but then again I am using a Easy Jtag and windows. the power supply drain is 1.1A but drops down do 700mA when connected with PC and Jtag. I saw on a few posts that if you increase the voltage then you wake up the Nvidia chip which will in turn ruin the eMMC.

it will be fine to use, but I would recommend the following:
1) 16GB in pseudo SLC mode, will allow much longer lifespan and extra space, not tested yet, but I have tested 32gb one
https://uk.farnell.com/swissbit/sfe...-std/flash-memory-16gb-40-to-85deg/dp/3786402
2) 8GB. same size, but also in pSLC so should run much better, overall id estimate this to last about 5+ times longer than original. I had this tested and works just fine with the Tegra.
