Re: How to Replace the Internal MicroSD Card - RT6

Post by Moarmo »

Hey everyone. My RT6 stopped working around last december and I was simply ignoring it until next time I head for the workshop for something. There they told me they have no idea how to fix it and I should contact an official Peugeot dealer about this. But they also hinted that this is gonna be expensive. That's when I found the threads here on the board.
Long Story short: I got the RT6 out of my car, disassembled it and removed the (11 years old) micro sd card. And sure, it is done for. My linux pc can read the partition table and sees three primary partitions on the card (sda1, sda2, sda3) together with their sizes but when I try to read any data from that block device, the driver starts popping I/O and "device offline" errors into the kernel log. Means there is no easy way I get any information from that card and the hard ways I read about won't probably work, too, if the controller is busted. Sadly this includes the user dat files.

I put a new card into the radio and from what I understand I now have to install the firmware. And I cannot do this via USB since there is no firmware at this point. Where can I get the ISO image and can I install v2.86 directly in that case or do I need to install an earlier version first and do the updates via USB afterwards? Also: I know I have to flash my VIN via Mirascripts and then try to reconstruct whatever was set in user_dat (button mapping? Localization? Branding for Peugeot?). Is there some kind of documentation for the possible options so that I don't have to do so much trial and error? Sorry for all those questions, I do work in IT for over 20 years now and do electronics and microcontroller projects in my free time (means I can solder SMD by hand) but all that car stuff is quite new for me.

Obviously we can't go into the specifics of the system here - as you probably are aware of now, the time to take the backup was when it started to go wrong and before the damage was done.

At this point there's nothing to loose by installing the new MicroSD card and just inserting the 2.86b firmware into the USB. It will reconstruct the partitions nad install the operating system onto the card when it detects this as missing or corrupt.

The only issue you will have is potentially losing some functionality of the system. What, if anything you will lose is not known 100%, and will depend on your pre-existing firmware version as this affects different vehicles with different options and firmware all differently.

If you do find after the firmware update that the system is missing some options and that it has reset to factory defaults, offline Diagbox wont be able to fix it as the system is locked down. A dealer can initialise it as if they were replacing it like any other part to be configured, which they do via server connection. Getting technician with experience of this is another thing though.

I can't speak for the other functions of Mirascripts, as that is something you'll have to find out for yourself as we don't support the programme here. Maybe you can find some info on Mira's website for other functions - but make sure you're only using the RT6 files as earlier systems are not compatible with some commands / functions.

I can provide you with the V2.86b firmware if you require on ISO or zipped files. Let me know which.

The only other function I used Mirascipts for was to remove the requirement to input a code when updating the map data. it can be used to adjust echo on a Bluetooth hands-free link to your mobile phone. There is a strong possibility that installing 2.86b will give you this problem.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Yes. Fully aware of that. And if I'd know back then everything is on a simple SanDisk 8GB Consumer MicroSD, I'd ripped the thing out of my car and dd myself a full disk image in that very second because it doesn't take much to realize that this is the single point of failure, especially with a FAT32 file system that writes a timestamp to the partition table whenever the file system gets mounted, even if it's just readonly. Ah, but that's the IT guy in me who had to deal with this kind of s**t too many times...

If possible I'd take both just in case. When I talked to a colleague of mine about this case he was like "Oh... wait a second" and start digging in his desk drawer pulling out a few unused CD-R disks. So I can go the USB way and if that fails I can try it with a CD as plan b.

Also I THINK I already had v2.86b installed on the unit, that number somehow clicked with me (since an intel 80286 was my moms first pc). But we'll see what happens. Thank you SO MUCH, you are awesome!

Well that may be the saving grace if you already had 2.86b on the system as it also updates the unit internally and that may mean it won't reset. I will send you the links in a Private Message.

As anyone worked out how to reset the language back to English on a RT6 everything seem to work after changing the SD card and installing firmware 2.86 but the unit is in Czech and i can't see any options to change it

Hello.
Don't you have a backup of your SD please?
I have been struggling for a long time with inserting the Czech language into my RT6.
Thank you.

If you have lost some settings, then a dealership should be able to re-configure it from their servers for the cost of a diagnostic. They just need to treat the procedure as i they were installing a replacement RT6 and configure it.

Hello,
My vehicle is 308 1.6 ehdi 2013, RT6 2.75 with a flip-out display.
For some time now, when navigating, the voice guidance along the route has disappeared (sometimes it appears, in most cases it does not). The system warns about cameras. Also on incoming phone calls the system does not respond if I do not answer the phone. There is no problem with outgoing calls. I rebooted the system several times, disconnected the battery for a while, no change.
Just in case, I made a copy of the existing RT6 user files from the original SD card.
Where should I look for the problem - in the SD card (the card is 10 years old) or in the device itself?

Most problems stem from the MicroSD card. They have a finite life.

This can be a sign that the files are becoming corrupt as the flash memory nears end of life.

Thanks for the quick response.
I have a new SD card (8 GB). Is it possible to copy all the information from the original SD card to the new one or is it better to install firmware V2.86b then restore the saved user files from the original SD card.

Neither.

First, I suggest you use a 16Gb card as the maps have grown and that is the recommended max. size for a replacement. Second, use Mirascripts Section A (to copy) and B (to restore) from the MicroSD replacement guide (unless I misunderstood you and this is what you have used). Don't try and put the card in a PC and copy / restore files as Windows will leave system files all over the place and this will cause issues. Third - if files are corrupt on the MicroSD card, you will just be copying bad files tot he new card....

Better to a) backup user files from the old card using Mirascripts, b) Replace the MicroSD card, C) Use Firmware 2.86b (assuming this is what you had originally before the replacement of the card) to recreate the operating system and partitions (don't format the new MicroSD card or put it anywhere near Windows) and if necessary afterwards, use Mirascripts Part B to restore user Data / configuration

It's all in the guide in my first post.

I understood you.
The original firmware is 2.75. Unfortunately I don't have the same one to restore it to the new SD card. I have from 2.77 to 2.86b. I backed up the user files from the old card with Mirascripts following the guide from your first post. Which Firmware should I use 2.86V or older? In some posts, it is stated about the appearance of echo during Bluetooth calls, after updating to Firmware 2.86b.

The Bluetooth echo mainly happens when upgrading from a version earlier than 2.7* Citroen can apply a calibration file to resolve this for you which only takes a few minutes if required.

My info suggests that an upgrade for this vehicle to 2.80 should be fine without any issues, but of course I cannot give you any guarantees, as the vehicle electronic architecture can make a difference. Yours is CAN2004, so my info suggests an upgrade to V2.80 should be ok, but again there is always a risk in updating firmware.

You have to decide whether you want to try this or leave the situation as it is, but options may be limited going forward if the system starts to deteriorate.

Thank you for the information.
I will try with v2.80, if all goes well and the system works later I will update to v2.86b.

I recently had a problem with the radio, the card died and almost everything worked, I uploaded version 2.86 b1, I managed to copy the user_com.dat file but there is one problem - it doesn't see the map satellites, I uploaded it, checked the antenna connection and everything looks correct, what else can be done. Unfortunately, I don't know what the previous version was. Does anyone have an idea?
