The file into the zip international firmware not correspond in that inserted in the tutorial!

So,this method install alternative recovery that i can install then firmware international like original without any procedure?


@Danilo-Spallino at least thats what the author says at the end and some people did as well. It is risky though, but if you want the I firmware it is maybe the only way.

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