Now It's Time To Flash Cm 12.1

Note: As i Told You To Flash Flyme 4.5.4i(international Version)First.If still not installed then you will not able to install Cm12.1

Why?

Ans: As this rom is for Meizu M2 mini and model number of both devices Meizu M2 and Meizu m2 mini are not same so in this rom its developer had scripted a script in that it will not allow you to install Cm12.1 until it Check Ether Its Meizu M2 mini or not(Our is meizu m2) if it had some problem it will decline further installation process

Like this "Error In Executing Updater Binary In Zip"
Steps for installing rom

1.Unlock bootloader
2.Install Twrp
3.download Cm12.1.zip in SD
4.reboot to recovery
5.wipe everything( It Can Wipe Your Internal Storage too So i recommend You to Get Internal Storage Backup Too)
6.install zip
8.reboot to system
It will take time for first boot so don't worry.







Note: Still Not Able to flash error still comes
then try this two below given steps
1)Try with Flyme 5 beta version it can be flashed(untested)
2)Decompress Cm12.1 custom rom then go to bin folder there will be a file name"otasigcheck.sh"
Delete that file recompress whole rom again.
not recompress whole folder just recompress all files wich will be there eg :boot.img,system,bin etc (tested working 100%)
After this you may not able to get features update so you if you want to update download manually :)
