First identify your sd card, you could do this by the lsblk command. Then do the command: nav-sdcard-format.sh -f /dev/sdx (replace x with your sd card letter) Warning: if you perform this on the wrong drive you could loose all your data, use very very very carefully!!

ic firmware is same as cid firmware, just copy the sqfs to p1/p2, and leave p3 and p4 empty (zero'd, dont even make a fs on them) then boot up the system and it should work like normal.

pm sent ;-)

I wonder where you sent your MCU to? Tesla will not handle a disassembled MCU, and a respected 3rd party repair shop would have been able to get your MCU working again, or at least diagnose what the problem was exactly... Did they check the mtd7 partition on the nor chip for corruption? My...

When the microsd swap will still result in a black screen then they will have to swap the Tegra/VCM module as well. Not sure what they will charge for this but it will be much cheaper then a new MCU. Keep us updated!

I can only support what @Flaminis is saying: in most cases Tesla uses smaller patches which are downloaded to the user data partitition (/home/cid-updater), then the data is combined with the data from the current online firmware bank, the result is written to the offline firmware bank, verified...

To be honest, this is basic linux stuff and this does not really belong in here ;) You can find these commands easily if you google it. But you can dm me if you really can't work it out (and don't mind a delayed reply)

in your case (to anyone else reading: please dont copy this dd command literally if you dont know what your are doing) just do from terminal: dd if=filename of=/dev/sdb1

I have sent you a dm

Lot of EU mcu1 cars got updated to EU-2019.21-12489 last week. Including my own car which was on 2019.20 before (since loooong time). It is so strange they use this "old" version (which has been around for over a year now), because there exists a newer EU-2021.8-12875 version. I guess they...

If you have a black screen because of the nav card failing and the Tegra is stuck in recovery mode then only swapping the MicroSD will not result in a working MCU. You would need to have the Tegra fixed (nor mtd7 corrected). If still needed DM me I can help you with this.

Yes anyone that has Toolbox access (ota/tbx3 or via service laptop) can see the vitals of the car, this will list all kind of details. When SYS_CD_emmcName says "H8G2d" or "HYNIX" then its the old 8GB chip, if it says: "S0J58X" then its the newer 64GB Micron. Alternatively if you can get the...

Het is in theorie mogelijk een S/X met MCU1 te downgraden naar een oudere software versie, bijv. naar 2019.12 (vanaf 2019.16 was er "chargegate"/"batterygate"). Het laden zal dan in de meeste gevallen sneller gaan en de capaciteit zal wat hoger zijn. Echter werkt door de (te) oude software de...

Did you replace the card only? Or did you partition the new card first with the script I posted earlier? Without proper partitioning it won't download the new maps.

The partitioning script is listed here. Run from Linux system or from some virtualization software like Docker or Ubuntu for Windows. If you pm me I can send you the EU map file.

I don't think you need Linux to make a 1:1 bitcopy image from a sd card. I assume there are Windows tools available that can do this just fine.

Now I'm in doubt about my prior statement on the MCU1.5 units. If your MCU1.5 still uses the external MicroSD card for maps instead of the internal secondary emmc then yes you can replace the current/old with a new card ofcourse. 1. I have not tested this but since there is quite some reading...

Facelift / 2016+ cars have the newer MCU1 (sometimes referred to as MCU1.5). This model MCU has a secondary 16GB emmc chip on the MCU mainboard where the navigation maps are stored. I have not seen any of these go faulty yet. Also on-board emmc is somewhat more reliable than a separate consumer...

Self diagnose can be done by taking the MicroSD card out and testing the card on a computer. If it is faulty replace with a 16GB or 32GB card, and ask Tesla service to initialize/partition the card and push a map update. (both can be done over the air) If you want I can provide you a binary...

4 to 5 minutes before the T shows or before the UI shows? Either way it is not normal, with a normal/healthy emmc they always boot like clockwork: 90 seconds till T logo, then another 90 seconds till UI shows. 3 Minutes total (besides the activating of 3G/LTE which can take some longer depending...

Heb m ook gekregen, als ik het formulier open krijg ik het VIN nr van mijn allereerste 2013 Model S te zien die ik in 2015 verkocht heb. Vaag ...

If you have a Linux system its fairly easy to test if the copied data is integer or not, the maps are in sqfs format so you can use a tool like 7z to test the integrity of the partition. But else you could just partition a new card, put it in and wait for it to download the maps automatically...

Wellicht interessant om hier te vermelden. De oorzaak van een zwart scherm zal in de meeste gevallen een falende EMMC zijn, maar er zijn andere oorzaken waardoor een zwart scherm kan optreden...

It can. But if you current card is still somewhat alive why not just make a 1:1 bitcopy of it to a new card? Then you don't need to bother with partitioning etc.

When the EMMC chip is healthy: about 90 seconds before you see the T logo. And another 90 seconds before the UI is loaded. And then another few minutes to load the 3G/LTE connectivity. 10 minutes is definately not a good sign.

The Parrot module controls the Wifi and Bluetooth of the MCU. The module is soldered on and a bitch to remove/replace. Not really an option unless you can do advanced pcb rework. Sometimes these Parrot issues can be resolved by re-flashing the Parrot module from root shell (script is called...

@sadmcu Sorry for the late reply, just stumbled on this thread by accident. I have done hundreds of Tegra repairs/replacements, and I know from experience that these so called FPGA errors can sometimes occur when the Tegra module is not seated correctly in its socket. This might or might not be...

Somewhat related so please check it out: MCU1: Black center screen / mcu failure caused by a faulty navigation MicroSD card

Hi all. Just a informative / warning message from me :) There is now a new, until now largely unknown, reason for getting a full black center screen on a first generation MCU1.0 found on cars up to and including 2015. This report does not cover the newer 1.5 MCU found in 2016 and newer cars...

Whenever you notice some laggyness try switching to radio (like AM/FM) instead of streaming music. The spotify and tunein can sometimes hog the cpu especially when cell reception is bad.

Correction: I made a mixup, the Hynix is for the older chips, the H8G2d is for the newer ones with VIN > 50000.

From the official service bulletin these are the criteria to be eligible: For the older Hynix eMMC chip (Model S VIN up to about 50000): For the newer Hynix eMMC chip (Model S VIN > 50.000 and all Model X): Basically this means the system already has developed extensive eMMC damage, and is...

I had one in my hands a few days ago. They are definately refurbished. @dark cloud @Akikiki it was visible that the chip was replaced (from the side I could see it was not perfectly sinked in), there was a extra sticker near the emmc chip, there were dust remains/scratches on the heatsink...

Zowel tijd als kmstand spelen mee. Meestal begint er pas iets te spelen nét wanneer hij uit garantie is >4 jr en >80.000km. Maar ik zie ook wel eens auto's van het eerste uur (2013) en met veel op de teller (>200k km) die het nog enigszins goed doen (traag weliswaar). Logger maakt nauwelijks...

Het getal is wel heel nuttig maar zegt ook niet alles, ik heb hier al auto's gezien met slechts 1200-1500 cycles (40-50%) die al een zwart scherm hadden. En ook wel eens eentje met 3900 cycles (130%) die nog soort van werkte (wel heel traag). Maar vuistregel is wel rond de 80-100% (2400-3000)...

Tesla bellen / mailen / langsgaan en vragen voor de emmc health, dat is een getal/percentage wat ze meteen zien zodra ze de auto opvragen in hun systeem (0 minuten werk dus). Als die waarde richting de 100% gaat (3000 schrijfacties) dan wordt het hoog tijd daar iets aan te doen. Die spiegels...

Klinkt inderdaad als een beginnend emmc issue. Niet te lang mee wachten, kans dat je scherm op zwart gaat binnenkort is aanwezig.

Zo'n scherm kost €495,87 ex btw en is direct bij elk Tesla Service center te bestellen onder vermelding van onderstaande nummer (is normaliter in voorraad): SX-MCU SUB-ASY, SHIP. OGS DSPLY(1084333-00-C) Gebruikt zijn ze ook wel te vinden maar dan heb je meer kans op sneller terugkomende bubbles...

Zeker, (bijna) iedereen is inmiddels aangeschreven en/of al vervangen.

Correct.

Hate to spoil it for you ;) Maar die bewering is niet juist, er zit 100% zeker weer dezelfde langzame en foutgevoelige Hynix 8GB chip in welke ook weer na zo'n 3 tot 8 jaar stuk zal gaan.

PM me :cool:

Voordat de speculaties hier uit de hand lopen: dit zal vrijwel zeker geen software maar een hardware issue zijn, de soldering, chip, of iets anders aan het Tegra bord of mcu. Er zijn vanuit Tesla geen aanwijzingen dat het vervangen van de emmc chip tot "Apple" acties zal leiden, eerder andersom...

Dan zal het geen software/firmware issue zijn want in die versie zou dat opgelost moeten zijn. Even in de gaten houden als het nu echt heel vaak gaat voorkomen dan kunnen we evt eens proberen de RAM chips opnieuw te solderen (reflowen), dat gebeurt ook wel eens bij grafische kaarten ed.

Eerste wat in mij opkomt is dat de elektronica een klap heeft gekregen van het overstarten. Bij mij is op die manier al eens het instrument cluster kapot gegaan. Maar vind het wel opmerkelijk dat je de auto/Mcu werkend bij Tesla aflevert en enkele weken later blijkt dat de Mcu defect zou zijn...

Houd er rekening mee dat ze je waarschijnlijk met een zoethoudertje weer wegsturen. "We hebben een diagnose gedaan en de mcu is nog in goede staat" etc. Advies is zodra je boven de 80k / buiten garantie zit en beginnende symptomen ervaart om te overwegen om de chip (preventief) te laten...

Voor de 4G/LTE upgraden hoeven geen antenne's aangepast te worden, er hoeft geen configuratie aangepast te worden, er hoeft geen software update gedaan te worden, het is voldoende om alleen het modem wat in de MCU zit te vervangen. 5x Torx10 schroefjes, en 3x U.FL mini coax antenne's (tip...

Yes it can booted standalone: Lunars/tesla $1200 is a bit overpriced if you ask me, you should be able to get one for half of that. Search ebay or contact salvage yards.

There are two variants of what is generally considered as "MCU1", both have the same cpu and emmc but have slighly different mainboard inside and a few plugs changed on the back. In the newer variant the Black plug is missing (wires repinned to Brown&Grey) and they use a separate BT antenna...

Not sure but I guess somewhere mid/end 16. this is how the cam pigtail looks: and the green one is the new bt antenna, also notice the brown&grey plugs got repinned:
