    Default Urgent Pls !!!(Citroen ds4 Emyway rt6 many problems after firmware upgrade v.2.20 to 2.86!!!

    Hi guys,

    I have Citroen ds4 with eMyway navigation rt6 version 2,21 and then I decide to upgrade firmware 2.86. Everything went fine however after completion of the upgrade Emyway rebooted but some problems I faced that
    *bootscreen turns to Peugeot logo instead of citroen logo
    *navigation button, ok button, and some other buttons not functioning properly or wrong functioning
    *no sound can be heard from speakers in radio mode, aux in, even when the car is reverse gear no sound in park sensors.

    I really try many things but I quite sure that the reason for the problem is upgrade! What can I do now?
    *I try many times reset(by long press on CD eject button)
    *I try lots of times to downgrade to v. 2.21
    *I search every forum's and still no clue for fixation.

    Finally I guess , I use wrong update file cause configuration of the device has already been set to Peugeot car.

    If I remove the sd card from emyway device and format, can I install v2.21 ? And also how can I modify the firmware to adjust all parameters compatible with my citroen ds4?

    Appreciate by now....

    You should not jump up to many versions without moving up in steps, as there could be extra files needed from each versions.

    You should also read this: [Only registered and activated users can see links. ]

    Go see your Citroen garage and let them calibrate the system by conneting it with the servers form Citroen.

    No. Go too the Citroën dealer the have the tools for it.

    Never upgrade it directly from 2.21 to 2.86.
    Procedure Install new firmware in the unit first 2.21 -->> 2.37 -->> 2.86

    i ve gone to dealer they fixed sound issues and rear parking sensor. However they told me that the back up file could not get from citroen server. I think wrong upgrading of the firmware erased all data. And the technician said he needs time to fix other issues because he has to set all other parameters by manual entry.( I understand that he will try one by one all parameters, if it's correct or not)

    Also I try to downgrade firmware to 2.37, I failed.

    If I found another Emyway same brand car back up file, would I fix the issues?

    You can't do downgrade. Try again with USB with 2.86. What I would do in your case I'd take out micro SD card and put a new one in and do clean install of 2.86. It worked for me several times.

    I feel you are counter acting you Dealers work and causing your own problems.
    Stop playing with things till your dealer has finished.

    Dealer failed. He said i can not download the required files. They give me no suggestion. I will ask another dealer which is 250 km away from my place.
    Also i m not counter act to dealer. I had 2 different issues with my car previously. They could not find a fix for me. There is no any other dealer in my place. So I lost my thrust to dealers that's the point.
    Anyway, I search in the internet that to download calibration file sometimes it requires to bypass VIN confirmation. I will ask another dealer.
    Thanx to everybody to try to help me.Urgent Pls !!!(Citroen ds4 Emyway rt6 many problems after firmware upgrade v.2.20 to 2.86!!!
