The failed emmc is a good option, You can speed this up by heating the emmc with a heat gun. The same way as if you were going to remove the emmc, the heat will definaetly speed up the process

did you put a different charger in the car? if you found a cheap one then it probably isnt designed for the hardware you are using. Did you do firmware redeploy, or update using toolbox 3? next, why are you replacing these things? are they different in Europe than US? If you are replacing then...

When you did this you need to connect your 12V battery to a power supply preferably set at approximately 14V which will allow for 20 or Amps (thats what I used). or have another car with jump leads connected.

yes you do in toolbox 2 but not in toolbox 3. once toolbox 3 connect it goes in to service plus mode which is practically the same

I am giving you this info from memory so not going to be very detailed, however I trust you can work this out. For this to work you need a good internet connection and I think that the car should also be connected. If car not connected then don't worry there are other points to check, because I...

how can that be done? I spoke with a tech from infineon and this is what he said: Thank you for contacting Infineon Technologies. Assuming that the RESET#, WE# and WP# are at logic HIGH (deasserted), VCC and VI/O have a 0.1uF decoupling capacitor with clean (undisturbed) input signals, and...

I have done it using dataman with a programming adapter

nice question i didnt know it has partitions xD

I have read online about the issue of what the part numbers are and so far this is what I have found the first 7 digits are used as the actual part number and that will differ mainly between different years, for example when the MCU changed from Nvidia to Atom. The last letter is normally the...

or maybe iis there a way to trick the spansion to happily hanshake with the emmc, if I change a small amount of data on it?

Has anyone got a list of spansion chip images that correspond to each firmware numbers? I bet not, but would be nice to have

https://service.tesla.com/docs/ModelS/ServiceManual/en-us/GUID-53A07C91-FEF0-4888-9478-4D5BD66847AF.html Go into the link. you may need to create a free account and then just follow instructions. This is for replacement not the fuses. I hope this helps PS I also thought tbhis was gen3 charger...

can you send a picture of that charger?

Has anyone successfully attempted to read the SPANSION chip on the Tegra board, without removing the chip from the board?

Some models have this ability. If you MCU has a tesla logo on the top middle, then hold it until you get an animation. Window will pop up requiring a code. Type 'service' and it will go to service mode

Just another read on this to make sure I am buying the right thing. To answer you, commonly you would use places like Halfords, its a big auto parts store. They also own mechanic places, but you want to avoid them. I took my 'new' BMW there for a free check. Centre console where the gear stick...

Thank you very much

nearest service center is about 20 miles away. I dont mind getting a non tesla one, but I dont know about the colours of it. and So far I am confused which colour it is supposed to be in there. Going to have a look

I am planning to change the onboard charger on Model S myself and found out it needs coolant refill, well that should be obvious as it does heat up nicely due to the electricity thing. I want to go with genuine, but whilst looking on Tesla parts it shows that this is TESLA ONLY. Does anyone know...

That is a good question. I am trying to access information on Spansion and actually read its contents via the processor

Yes it has, If you power the MCU on the bench and connect a metal wire to the correct place, you will get a stronger signal

I dont think that this should be a problem.

The is a full DIY on all models how to replace the onboard charger on tesla service website. You need to create and account and there you can find a complete how to.

Could it be the onboard charger gradually wearing out? The reset may be works, but would the factory reset give you older firmware, which could potentially be slower in diagnosing the problem. or perhaps you deleted the fault logs so car had to learn once again to give you the fault which may...

Yeh, I have been looking to replace the charger on the car I have and the only replacement here in EU matching what I need is nearly EUR2000, others are cheaper but look water damaged. Even if its just changed with a used one then how long would it work for? Whilst searching i didnt find them...

Did you use the IC from the same car as the MCU?

Very interesting post on here. I am currently working on a process to be able to replace these for the fraction of a price than tesla does them. I will be working to see if I can do these on Model 3 as well. Thank you for a lot of useful information. I hope we can find what breaks on these to...

in your other post you mentioned that you cannot connect. I am wondering if when you downgraded did you put old verts into the car? I guess thats unlikely but since they do get updated then there could be an issue

No, the tegra is off. I only power up from power supply. I have found another way to force mount the images, but I have to be in root. It works just as I wanted it to which is great. However I heard about the fsck and would like to try that too so thank you for this input.

The certificates get updates every now and then(least what I read) when did you make a copy and how long after that did you put it into a new chip? Also the certificates could had been in a bad sector of the chip so did not copy correctly.

I am not able to mount partition 3 or 4. Even if I take an image and mount it, then it comes out with the same message Can anyone clue me on this? Code would be a blessing in the sky. Thanks

translate each sentence then copy and paste here. or write in Russian and put translation here. You can also use microsoft word translation feature, which works better

I was actually thinking whether also copying partition 1 and 2 from The MCU Tegra to IC Tegra would solve the power on problem? Although that is a bit of work. I actually am not sure of the IC pinout

I am Looking for Model S or Model X Center display screen (MCU) needs to be working and from a model 2016 or newer

how did you connect the IC? Most likely it wont work. The IC i have wont work with another MCU, or at least I dont know how to make it start neither, but it works perfectly fine with MCU from the same car

Hi KyleDay, Do you know where the command lines for are listed? I am trying to unlock the screen. Bought it online but it was left locked when it got taken out out so i presume a good crash happened. I also would like to try and attempt cloning where the MCU saves information into the IC, but...

HI red_five Do you have a list of codes for Model S? I have bought a spare screen, but it looks like it was taken out the car when it was locked I am certainly looking for one to unlock this. I do not have physical keys for this. Thank you

So your thing looks good. I normally have it like this and put power supply to run 13.7V I do have a spare harness though so i dont have to worry about what goes where Yes I could not power on the cluster if it was from a different car, but what I havent tried is connecting it to an MCU with...

Are you sure you got the right connections? If not then send a picture. If all good then please let me know what voltage you have set and what current you are getting

I do not think that toolbox can tell if the chip was replaced. It would be in Tesla customer Log if that was done by tesla service center. Otherwise you can take MCU out open it and check on the Tegra. If it is SKHynix H26M42003GMRA or something very similar, but still SKHynix then it has not...

How bad is too bad though? I have been on board reading the eMMC. While it does read successfully, when i compare the files of partition 3 then there is between2-3KB of data always different and it appears to be in the same locations. Similarly this happens in other partitions and the size of...

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/sfem016gb1ea1to-i-lf-12p-std/flash-memory-16gb-40-to-85deg/dp/3786402 2) 8GB. same...

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...

exactly

Let's this kind of a car is sold to high end audience who with some sort of education or brain will ask themselves the right questions before judging, especially as the evidence is as good as the he said, she said bulls**t. I would like to see a video of this crash, as well as speed.

Hello, I noticed you offer some answers, not necessarily to me, but I thought id ask you ( I posted similar question in another thread so ignore that please) I am trying to replace the emmc and I am able to read partitions and fully copy them onto a 64GB swissbit. Would it help enlarge...

Hello all, I am fairly new to this and even though there is now a recall for the MCU blackout, there are also people who cant get it fixed now and I am also playing around to see how to replace the chip mainly to get some insight into electric vehicles. I want to replace the 8GB to a 64GB. Does...

Moderator comment - moved from "Looking for TEGRA 3 BOARD needs to be working, will consider not working ones" Hello All, I am looking for as mentioned the Tegra 3 board (the ones with the emmc on it) I would prefer if they came from a working one, but I will consider ones that made the screen...

Hello, I am trying to replace the eMMC chip and i am confident I can do it, but I am still trying to find all he correct steps and in doing so I came across a few questions. Firstly I am using the easyJtag to read directly from the board to save the partitions and I am going to write to the new...

I have connected the power on the black connector, I also had pins 5/15 connected to oscilloscope. I am looking for the screen to display something. I had it also connected to a working car but the screen was still black and I thought it stays dark due to some combability issue
