How can I upgrade m1 note using update.zip?

I bought a Meizu m1 note which is China Unicom Version.
But I couldn’t using NTT DOCOMO network. So I want to upgarade it with
Universal Rom.
Please show me how to upgrade using update.zip.

Well, you could take a look in the topics on the other Meizu Phones, since the update principle is the same. It is basically this: store it on root, unzip the file and press the unzipped file and you will get an update window.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
