I have already performed software updates several times with Forscan, always without problems. But now I have a little one. I would have liked to give my IPC a different view, so I changed the BJB file. When testing the firmware, it started with the bootloader, but nothing else happened, so I thought, programming directly. It seemed to start, but immediately I got the message as in the picture. No matter what I tried, no matter what settings I changed, nothing happened. I'm probably overlooking something, so I wanted to ask for some feedback along this way.
I have a OBDLinkEX with the latest firmware. (and Forscan 2.4.5) All other actions work well with it. I did a firmware change to a digital speedo in the middle about a year ago, also no problems with it.
Where should I start looking?
Thanks in advance !
