Firmware corrupt

Hello, could someone help me? I try to update my Meizu mx4 pro. Now I have android 5.1.6.0G and i am trying to update to 5.1.8.0G or 5.1.9.0G, but everytime when i want to update, it says Firmware corrupt. Version seems to be correct. I downloaded from official Meizu website. Any ideas? Thank you!

Meizu Pro 5

Have a look to the wiki… Installed rom doesn’t confirm the phone version you own

If your phone is chinese then you canot update it directly. You must download the update. Then root the phone. Then install su. Then install busybox. Then install terminal emulator.Then you must use a tool to produce-extract a setup.img file from the update.zip and then to write some code to terminal emulator. Google how to put international rom to chinese mx4 pro and you will find everything.

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