I think you need to take your device to a service center
Try this. READ FULL Instructions TOP TO BOTTOM. Follow correctly. Also available in the website link above.
Once this is done try checking update.
(this is actually a downgrade firmware target to 72version, but this may work.)
What will they do?
Reflash the firmware
Note: doing this will probably wipe the data
It will which is why BACKUP is necessary.
I used downgrade for pie and its complete now.
Now build number is PKQ1.WW_Phone-16.2017.1912.072-20191125
It works 😊
Go to settings and check for software update. There will be a software update. Download it and see if it installs successfully.
There is nothing
You may try after some time or days. Available update might pop out.
If not, download the firmware file and update manually.
I'm upgrading with manual method and now its PKQ1.WW_Phone-16.2017.2004.075-20200407
I'm still doing this with manual method
The latest version is .097 so there will be a lot of software updates for you.
Can you please send me the link?
Asus hasn't made the .097 update available on their website. Only the .094 is available
Link for .094 firmware
Still .097 update file is not uploaded to server by Asus. Not available to download now.
