If you have the WIP NA to EU Conversion zip file (9.3gb) then you have Script - Backup, Script - One and Script -Two.
Script - Backup is similar to the other back you file you are talking about. It backups the Maps and FRAM files along with some App files.
Script - One replaces the FRAM files to enable the instalation of the v17.07.46 EU firmware, so is the start of the conversion, instalation of the 17.07.46 EU firmware finishes the software conversion
Script - Two Replaces all the Maps and the support files to enable EU navigation and Tuner, completing the conversion.
It includes detailed manual, made by you SquithyX. Thank you !
I will run it next days and will report status.
And update failed. Moreover radio has stopped on the Loading... page.
First issue happened after script one finished. I have exchangeds usb keys and I have got Authentication failed from the second USB (tried twice).
I restarted the car but now radio is frozen.
Could be the cause comes from the sd card inserted into the radio during the modification. Based on the script it does changes on mmc so it could be it did it to my sd card not radio mmc0 and it caused the issue.
