Phone not updating

[pottakuzhyanand]

Phone (zenfone Max pro M2) not detecting any updates. Tried manual ways too.
System update failed (3) unknown error system restored to previous configuration
Manual way :the zipped firmware file is in phone memory main page itself (moved from " downloads " folder. But when tires to reboot ,it reboots as usual (not detecting any updates).

Then tried through BIOS . But says installation aborted

Still in Android 9. (Details in screenshot)
Want to move to latest version provided by Asus ( that version in screenshot attached)

Done one update in 5th June 2019 (which was successful) , after that tried to update but atlast (after booting) it says update failed system restored to previous configuration . Please help me and thank you for reading this.

Try to factory reset the device and search for auto update if not try to update manually.
(Take backup of Internal Storage to avoid data loss before resetting)

If above didn't work, visit service centre they will reflash the ROM.
