PSA NAC RCC Updates

[toudubon]

Hi everyone,

I own a Toyota Proace Verso 2019 with a NAC Wave 2 infotainment system. I'm trying to update the firmware via USB but the Updates list remains empty, I believe I'm missing the licence file.

Here are my current system details:
- Vehicle: Toyota Proace Verso 2019
- System version: 21.07.16.32_NAC-r0
- Mapping: 10.0.0-r0
- Target firmware: 21.08.87.32_NAC-r1

What I've tried so far:
- Downloaded the firmware .tar file directly from the PSA server
- Placed it at the root of a FAT32 USB stick (16GB)
- Extracted UpdateInfo.xml from the archive and placed it at the root alongside the .tar
- Attempted to connect via iPhone hotspot to retrieve the licence OTA, no result
- Toyota UK website does not recognise the vehicle VIN
- The NAC exported an instkey file via the Export Config option

I have attached my instkey file: instkey_0D01081F19D4EE802818.xml (added .jpg so it would be accepted as a download).

Would anyone (particularly @GiveMeABreak or @rui_saraiva) be able to provide the licence file for firmware version 21.08.87.32_NAC-r1 based on this instkey?

Many thanks in advance,
Denis

@_LCLM_: You probably can use the Peugeot Update software. But you just have to extract the .tar update file to a FAT32-formatted USB flash drive.

@owl: It doesn't identify some VIN and it doesn't give any error?

@Sergio Ribeiro: Are you sure the Citroën Update software is offering the 44.07.33.32_NAC-r0 firmware version? AFAIK, currently any NAC_EUR_WAVE4 system has only been offering the invalid 44.06.44.22_NAC-r0 firmware (with an expired signing certificate). Anyway, there are also 2 "available" versions of the 44.07.33.32_NAC-r0 firmware, with 6 312 212 480 and 6 312 210 432 bytes, only the former is valid (the one linked on my page). If you connect your car to a WiFi network, you don't need the license on the USB flash drive. If you still need the license, you need to post (or send me) the full VIN. For privacy reasons, all VINs on this forum are automatically obfuscated, only forum staff could read them.

@toudubon:
Any reason you're trying to install the older 21.08.87.32_NAC-r1 firmware version? That version is too old and already has an expired signing certificate (so, impossible to install).
The license for the latest 21.08.90.52_NAC-r0 firmware version could be downloaded at: https://majestic-web.mpsa.com/mjf00-web ... D4EE802818
You just have to extract the 21.08.90.52_NAC-r0 .tar update (it's just like a zip file) to a FAT32-formatted USB flash drive and copy the "license_0D01081F19D4EE802818_001315031666020829.key" you've just downloaded to a "\license" folder on the same USB flash drive.

Well, most probably citroen servers recognized my system as wave4, because citroen update doesnt show any update (before it was offering wave3 even on my system wave4 installed). I wanted to check via your site, I am writing VIN and click OK, it shows nothing. Maybe you can check V R7 AC YHZ RLL 018090

Thanks for the quick reply! To clarify: the app is indeed offering 44.06.44.22_NAC-r0, not 44.07.33.32 - I mixed that up in an earlier message, sorry. That matches exactly what you described (the invalid one with the expired cert).

I can connect the car to my phone's WiFi hotspot, so I'll try that first and skip the license on the USB drive, as you suggested. I'll report back once I've tried it.

Appreciate the help!

@owl: It is identified as an NAC_EUR_WAVE4 system on my site.

Some (not all) systems that had a NAC_EUR_WAVE3 system from the factory (with a 3x.0x.xx.xx firmware installed) and then upgraded to a 4x.0x.xx.xx firmware are now being correctly identified as NAC_EUR_WAVE4. Some are still being identified as NAC_EUR_WAVE3, and those are stuck in whatever 4x.0x.xx.xx firmware version they have installed. Only Stellantis knows why...

Previously, they just blindly identified some NAC_EUR_WAVE3 (and worse, NAC_CN_WAVE3) systems as NAC_EUR_WAVE4, even with 3x.0x.xx.xx firmware installed.

Thanks God! Stellantis recognise it as WAVE4 finally. Thank you mate!

Thank you, merci beaucoup! I hadn't noticed there was a newer version available. Really appreciate the licence file and the clear instructions
