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🙂

Thank you for the sugestion, but I did this procedure using "MaxProM1_downgrade_to_9". It gave me .60, but I'm unable to go to .424
The 424 description says: "This version is only for WW SKU device that with Android 9 OS WW-16.2017.1910.059 & WW-16.2017.1912.060 version."
But it is not working on .60 version...

Hi wesley.b.peres & all,
Sorry, if you would like to update to Android 10 WW-17.2017.2004.424, you can update from WW-16.2017.2004.063 or WW-17.2017.1911.407.
The relevant team is adjusting the description under WW-17.2017.2004.424. It takes some time for the system to renew the website.
Thank you.

Hi syedifty
Thank you for your asking. The issue of WW-16.2017.2007.084 is now under investigating, please try auto update first. If you still like to perform manual update, kindly try it again on Saturday.
