My Meizu is on Flyme OS 4.2.0.5U

Careful.

Your m1 note might be running the Q firmware, which isn’t a Android rom.

I advice you to flash an A firmware, then you will run 100% Android.

I figured it out, I tried to install it and it worked, last time before I restored the firmware I get errors, only difference I have that SuperSu is installed, I think maybe Xposed installer couldn’t get root access with the stock permissions manager…

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