When the downgrade file is downloaded from the phone, it is missing and gives an error during the installation. When downloaded to the computer and copied to the phone, the process is provided without any problems.

Hi felipefreire200t & cengizhankirac,
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.
