Manual firmware update (for new charge port)
- Thread starter janisv
- Start date
PC IP set to 192.168.90.101
Connected into the CID via the IC connection (i have fitted an extension cable so I can split the CID-IC connection and add the Fakra HSD to ethernet cable easily)
using the command telnet 192.168.90.100 25956
I can ping 192.168.90.100, nmap on 192.168.90.100 shows port 25956 is not open

If I remember well, MCU1 can be accessed with a password that changes periodically. MCU2 uses certificates.
Yes I do have root access now thanks to very kind help from a member on here.
cid-updater had been disabled from running at startup. I have got it running and have now updated the firmware.
Still working through the issues caused by someone who has previously hacked the car. But I will get there eventually!

I want to swap the charge port ecu with newer generation 4. Per service manual it says that I will have to update the firmware once hardware is replaced. Is the factory redeploy still possible via ethernet port and more particular on model 3 with hw2.5 2020.48 software? If not, is it supported via tesla official toolbox 3?

Rumors are Tesla locked down some stuff in 2019/2020 and its a lot harder to get in as an owner.
Toolbox 3 should have this, not sure.
Have you contacted tesla and asked them to push a full firmware reinstall? Even if its a salvage, may be worth a shot.
Can do everythng. Install update, redeploy, unlock sc, change regions. Firmware version is not important.
Would you please kindly PM me. I am interested in some details about flashing a different firmware on my new M3

You can’t flash that far into the past due to security versions on the ice and the bootloader

Just replaced my onboard charger with a used one. Old one was only charging at half-rate on Level 2. Gen3 charger...not a fuse problem.
Errors: "Software Update Required" "Car may not restart...service needed"
Verified car won't start or go into drive. HV Contactor not closing. Guessing my problem is needing a redeploy of firmware to "new" charger. I have 2020.48, AP3, and MCU1.
I know this thread is a little old. Will the telnet redeploy option still work for me or is it locked down after 2020.48? I ordered a Fakra HSD/Ethernet cable but it won't be in for a few days.
Options I can see:
1. Tow car to service center and pay to reload firmware ($$$)
2. Tell service center that I replaced charger and have mobile service come out to redeploy ($$)
3. Wait for tesla to send new firmware...seeing that I'm on year old firmware, I don't see this being the best option (No car for a while)
4. Wait for Fakra and give Telnet a shot ($)
Since the HV contactor won't come on the, the 12V battery died, so I have it on a charger now.

Yea, the MCU1 firmware upgrade was more of a joke. I know I'm stuck in 2020. Lol.
Thanks for confirming that the redeploy works! Not a completely lost cause yet.

So, no way to issue a factory-redeploy on 2020.48?
I tried and I get the "unauthorized command" response.

I'm so close to fixing this. I can issue reset and handshake commands.
Factory-redeploy and service-redeploy are "unauthorized commands"
Running 2020.48.37.8
