Update to 29.1
 

Hi,
i updated my mk4 to 29.1 successful. Now i have changed navboot and burned it again. But my mk4 says, that i have the newest version yet and aborts the installation. How can i install the modified 29.1 version?

Downgrade to an earlier OS version, and then reload your modified V29.1 version.

You can downgrade, but you should be aware of posible side effects that you may not wellcome.

Alternatively you can upgrade to your "custom" version by branding it to a number higher than 29.1: hex-edit files lng_rel.tbl and sw_rel.tbl in \V_2\RR\0101\BMWC01S. The first four bytes "0910" indicate the software version (29.10). You can simply edit the fourth byte to brand your custom version as 29.11.

These are binary files. Do not use but hex-editors with them.
