Problem: Meizu MX4 Pro bootlooped

Guys i tried the terminal emulator method to update my phone meizu mx4 pro.......after starting the phone became unresponsive and now its stuck at logo screen. I made system image with 4.5.6 I firmware. previously i had 4.2.8.2U.

I can only go to a mode (Power + Vol up) where i have two options : upgrade and clear data (it has flyme version of android)
Phone is stuck at logo screen. When connected to PC it does not detect internal storage. In PC's device manager it shows as google nexus device.

I dont know how to go to a CWM recovery mode or if it exists for my phone.

I really need some help!! Please help.

[ROM] CyanogenMod 12.1 for Meizu MX4 (20151009 testing update)

Hello, I've updated the CM12.1 testing package and translated the release notes at my blog. Also took the time to support Disqus for the English blog posts... the release can be found here.

Also that I will stop regularly updating the port at October 20th, having to allocate much of my time to academic work. Security updates and minor bugfixes (as in not requiring massive porting) will continue as usual, however. Feel free to make ssuggestions!

(Note: I don't know how to patchrom so I can't do the Flyme camera app porting, or anything but the easiest features requiring porting of closed-source components, sorry about that but I'm primarily a Web/Android developer and as such don't have much time to learn about smali and the likes.)
