Hello,

I'm trying to update the firmware of my Zenfone Max Plus M1 (X018DC), firstly to Android 8.

The version is currently the WW_Phone-14.00.1708.5.20180808.

I already saw different topics on this forum, as this one, in which the problem seems similar:

I already tried to update with three different versions, but none of these are detected by the phone (I don't see the pic described below)

  • UL-ASUS_X018D-WW-14.02.1711.22-user
  • UL-ASUS_X018D-WW-14.02.1809.69-user
  • UL-ASUS_X018D-WW-15.02.1810.347-user


Furthermore, when I'm going to the System update tab on the settings, the last verification date is 01-january-1970 and I don't see the "Check update" button!

Thanks for your help, and merry christmas!

Regards
