That is the latest version. The last digits indicate that. Also 85C means the latest version. I had 84C prior updating.Thanks, we did that and it actually "worked". He became the message "no update needed". I am really confused now... in his system the iMX version is: x0401074_200326_19.1E028.5. How do i find out, if the update 4_085_19.1E028.5 has anything to do with it? I mean yeah, the last digits are exactly the same but I can still not understand how this versions system works (sorry for my poor knwoledge but I am used to work with SMEGs and NACs).
