Conversion of US > EU
:::info Unit can be converted via Manual SWDL by skipping the update of some partitions
:::
Below is just a bricking example that many got while trying to convert MSTD_US_VW_P4430 or MSTD_US_VW_P3470 etc without knowing what to skip: 
to MSTD_EU_VW_P4470 by adding a variant to the very end of metainfo2.txt after the [signature] lines like:
[common]
Variant="17147"
Region="USA"
[common_Release_2]
Name="MSTD_EU_VW_P4470"
path=".\VW_PLUS_SSB\"
Variant="17147"
Region="USA"
and correspondingly into metainfo2.txt in VW_PLUS_SSB folder:
[common]
Variant="17147"
Region="USA"
This allows to install EU firmware update: 
But when the update finishes, you get endless bootloop: 
The reason of the bootloop is crash of CPU_HMI.EXE (the log is collected via quadlock via TTL adapter on 115200bps speed)
