Hello friends peugeoth I wanted to do a smeg screen update for my 2008 2014 model tool, I read that the latest version like 5.43 can be installed on the internet.I downloaded the file to the internet. said. After the process was finished, the screen restarted, it remained in the peugeoth logo. I waited for 1 hour, nothing happened. I turned it off and opened the tool. I guess it was brick how can I fix it.

I changed the FLash disk, reinstalled it, the screen turned on but incredibly slow and freezing. In version 5.43

Before this kind of update process, you must make the vehicle connected to the Internet via Wifi with your mobile phone. In the update, the vehicle interrogates the information such as License etc. thrown into the USB from the internet. If you cannot query, you may encounter problems such as not opening, etc.
