Downgrading softwareThere is a way to downgrade the software on the RNS-E without hacking DVDs or doing other fancy things. All you need is a VAG-COM (or a friendly dealer). This may be of help in case you have accidentally upgraded to the 0330+ Euro software (and don't have a 2005_1 or newer DVD) or have otherwise the need to revert to an older version of the software.
To downgrade the software, have an older DVD ready and follow the steps listed below:
- remove the DVD
- connect with VAG-COM to #37
- set channel 97 to 1 and save the value
- exit VAG-COM
- insert the old DVD that contains the software you want to downgrade to
- wait until the RNS-E finishes the update (starts a few seconds after inserting the DVD, will reboot twice and then power off)
- connect with VAG-COM to #37 channel 97 and save the value of 0
Please note that this will not allow you to change the region (US to Euro or Euro to US). To use a Euro RNS-E in the US you will first need to load the US software using a higher sofidx and then downgrade the software using the US DVD with sw 0020 or 0110.
