I’m trying to install Android 7.1.1 Nougat on my Umidigi Z Pro (update version numberUmidigi Z Pro V3.01_20170605 released on 7th June).
The update downloads OK, but when I try & install itshows it’s unzipping then I get the following error message: -
Installation Failed. Package error. Please check update anddownload again.
Any suggestions?
Cheers
Cliff
