Hi all,
If you're on WW-16.2017.2002.061 or WW-16.2017.2004.063, and would like to update to Android 10 WW-17.2017.1911.407, we suggest that you first downgrade to WW-16.2017.1912.060, then you can successfully update to Android 10. 

The downgrade file and instructions could be found under "MaxProM1_downgrade_to_9" in the link below.

Thank you and have a nice day🙂
