  1. Doesn’t work as those instructions are not for Adb they are for updating via SD card, Adb you must use a PC to issue manual commands. The file is also missing Google update libraries.

  2. Did you actually try to install it manually? Manual install is blocked on Nokia 7.2 ! Could be good to check your facts before posting an article.
