how do i do install A version?
Download update.zip from http://downloads.meizufans.eu/mx5/firmware/stable/18.104.22.168/a/update.zip
Put that file in the root folder of your phone, then open the “Documents” app (it is the meizu’s file manager app), find the update.zip and tap on it, that easy :)
(P.S. You won’t lose app/data)
