Good News -> I found a way to install the G rom on a A rom successfuly…
It doesn’t require anything technical -> just root the phone in the flyme account parameters -> then download the Superuser App from chainfire on the playstore…Allow SuperSU to have root access
Then download the G rom (184.108.40.206G) and put it in the root folder of the MX6.
Then again download the App Flashfire from the PlayStore and from there you can directly flash any rom you like ->
First time I tried it didn’t work and I thought I’d bricked my phone cause it was stuck on the meizu logo for like 30minutes. I rebooted the phone and it lauched back with the A Rom…I tried a second time and it worked perfectly.
If you want a detailed way to do that check this tutorial http://bit.ly/2dJoOK0
Only downfall -> you canno’t update the rom directly through the update app…you will have to flash the new rom everytime using this method…but hey it works and it’s really simple
