PSA NAC RCC Updates

[Kakirman]

Hello everyone.
I had no problems with the update I did last year. I created the latest update (21.08.90.52_NAC_r0) with the Peugeot Update program and started to install it on my vehicle. While everything was going fine, it went to a blue screen error. For two days I have tried many different scenarios, I have tried different USB sticks, I have tried manual installation methods (without using Peugeot update, Fat 32 formatting memory, folder directory installation etc.).
I even bypassed windows defender during installation.
I work in IT and although these things are simple for me, it drove me crazy for two days. As a last resort, I removed the fuse of the device so that the battery would not run out. Because even if you turn off the car, the blue screen stays on.
I wonder what could have caused this?

Is there a problem with the latest version? Is it possible to share the previous version file (with the latest version). And if the license file of the previous version also changes according to the chassis number, do you have the possibility to produce that too?

And finally, which scenario could I have missed or forgotten?

Also, is the license file a single vehicle-specific file? In other words, does the license data remain constant or does it change with each version change (if it is different, can you produce the license file of the previous version)?

I would be very happy if you could guide me.

Note: I just did bsi reset. The screen still switched to the incompatible hardware unplug usb memory warning.

Scenario Summary
1. I formatted the flash drive in the fat32 system and also selected the file allocation unit size as "default allocation size".

2. On the other hand, I started to download the file "PSA_ovip-int-firmware-version_21-08-90-52_NAC-r0_NAC_EUR_WAVE2" again with the Peugeot Update application.

3. After downloading the firmware file with the Peugeot Update application, before the upload step to the flash drive, I created a new folder called PSA in the "Downloads folder" to create a manual flash drive and backed up the downloaded files there. Because the Peugeot Update application deletes the downloaded file from the system after writing it to the flash drive.

4. This time I gave it another chance and let Peugeot Update do the job (create the Flash Drive). If you remember, I also backed up the files in the folder I created to create a manual flash drive in step 3. With this, I will also prepare a manual backup flash drive.

5. I also prepared a second manual flash drive. I loaded the tar file content to the flash drive with the 7zip program. And I added the license folder in the flash drive that the Peugeot Update application had previously prepared to this flash drive that I prepared myself.

Result:
I made the installation with the flash drive that I created with the Peugeot Update application. It gave an incompatible hardware error. I tried it with the flash drive that I created as a second backup. I got an incompatible hardware error again. And I tried it with different brand flash drives. But the result is disappointment. I can't believe that such a simple problem has become so absurd. I have officially lost interest in the vehicle. Or I will replace the 2nd party Android interface screen without even going to the service, but it is a budget issue.

Hello,
Today I downloaded the screen update via Peugeot Update. The update was installed with the engine turned on and then I got the message: Firmware update failed
Version not compatible with hardware!
Please remove the USB stick!
I downloaded the update from this thread and added my file in the license directory.
4 pendrives and each time after a few seconds the same message.
I have to disconnect the battery before each attempt.
The car does not turn off and the battery discharges.
HELP!

Disconnecting the battery and reconnecting isn't going to work! You need to do a proper BSI Reset / Battery Disconnect / Reconnect Procedure

When you are at the disconnection part, leave the battery off for a good 10 minutes. But before you do this attempt, make sure your car battery is not discharged. If it's over 5 years old it will probably be due for replacing.

You don't really need a licence file as your vehicle has built in Wifi, so will authorise the firmware update itself. Just make sure you leave the engine running throughout the process and that you have waited a few minutes after starting the vehicle before inserting the USB. Also, make sure you have not disabled the telematics system.

I have included the licence file below in case you have a problem with OTA authorisation, but do not mix licence files up - tey are specific for each firmware and vehicle.

Read the instructions in the link properly.

Firmware 21.08.90.52_NAC-r0

Instructions for Updating NAC or RCC Firmware, Maps & Licences

I think the problem is in the software. what you gave and the key is the same that generates Peugeot update.

Hello everyone.

While everything was going well, we also got the famous blue screen. I haven't tried any scenario in 2 days. I also tried different memories. I also tried manual loading methods (Fat 32 memory, folder directory loading etc.)

Note: In addition to all my efforts, I did not just reset the BSI.

I'm in the same place

Just about everyone else has resolved these problems following the instructions.

It is not the software - it's the same one from PSA server's that everyone else is using. It's either at the user level or getting the Head Unit to reset via the BSI, the media not being formatted properly or having hidden user files on the route of the drive or other issues most of the time.

The other possibility is a failed previous update has left it with a problem (like removing the USB during an update). Make sure you follow the BSI Reset / Battery Disconnect / Reconnect Procedure properly and leave enough time for the Head Unit to shut down and DON'T open any doors as instructed, otherwise the BSI reset will fail because the vehicle networks will remain active and not shut down.

Oh, and one other reason if the Head Unit has been replaced with a used unit and not coded correctly.

Thanks for the answer.
In short, I did not interfere with the USB stick in any way while updating. I had already upgraded the same way last year and I had not experienced any of these problems.
The unit cannot have been changed because it is original equipment and I bought the vehicle from an authorized dealer (although it may have been changed, I did not experience any problems with the update last year, for example).
I format the USB stick slowly in fat 32. I have also tried other sticks. Or I will buy a brand new stick and try it out.

Since the vehicle's battery was in a closed box during the BSI reset, it only had a (+) terminal mechanism. Therefore, I disconnected the (+) terminal and waited.

Also, can I use this license file in all other older versions? Do you have any information on that?

The last resort is to go to the dealer.

Thank you very much for your help.

I wasn't suggestion YOU personally had done any of the above - these are just general reasons why updates can fail.

No, you cannot use different licence files - these are uniquely generated for both the vehicle and the specific firmware version and are not interchangeable.

As per the BSI reset, removing the '+' terminal when the negative '-' is inaccessible is ok, just be careful to avoid short circuiting.

Post up a picture of your USB folder contents in the route, so I can check to see if there is nothing obviously wrong.

Below is the content of the USB stick I created with Peugeot Update...

SWL folder contents
There is a numbers folder in the SWL folder contents. Under that folder there are also Certificates folder, Firmware folder, MediaHeader folder and HashList file.

Sincelery...

[GiveMeABreak]

Ok I can see the problem straight away. You are missing the Updateinfo.xml file from the route of the USB. Without this the system cannot update!

Make sure you use the latest version of 7Zip to extract the contents of the firmware file to the USB.

[Kakirman]

In the flash memory that I created in the second manual, I created those files with the latest version of the 7zip program. When I said guide, I made a spare usb stick. I threw the files with Manual 7zip. (without using the Peugeot app)
I did as you said in the sequence in that memory.
1.license
2.SWL
3.Updateinfo.xml



So it's a very interesting situation.

Well, let's add this ubdateinfo file to the flash memory created by the peugeot application, let's try it like that.

Best regards...

[GiveMeABreak]

Not sure what you're saying: "I created in the second manual"? - but there was no updateinfo.xml in your image. Once you have extracted all the files correctly it should work fine.

[Plant38]

So followed the instructions to the letter used a pc and several different usb sticks all to be confronted with the same error

Hardware not compatible

The maps at one point did try to update but then just said update failed before even loading anything

Any ideas please ?

[Plant38]

I’m also wondering could the radio have been changed at some point as it has 6 physical buttoned in it on off them with an arrow for the sat nav? Not seen this on other radios as I have been looking around!

[fasi]

I think I've tried everything

[GiveMeABreak]

I have this version on my vehicle and have done since 2022 without issue. I can't comment on the above though.

If you're having issues, then you may need to contact your dealer directly if the update is being offered but you are unable to install it.
