Model Name: ZenFone 8
Firmware Version: WW_31.1010.0411.138
Rooted or not: not
Frequency of Occurrence: repeated and repeated constantly (with small pauses)
Recently my cellphone starts trying to upgrade to new firmware version (WW-31.1010.0411.160).
And it constantly fails no matter I've connected by WiFi or not.
I decided to download the upgrade and install it manually, so I got it here, from ASUS.
I already did it before for versions 122 and 138 as I had same issue with installing over a network.
However manual installation fails too!
What should I do and how to stop my phone from permanent notify/download/fail dead cycle?
It is very annoying and meaningless.
I recommend that you do a full backup of your device a complete a factory reset and try to upgrade from there.
Additionally, I recommend that you read the following troubleshooting FAQs on how to upgrade the firmware and what to do when it fails. Thanks!
