I had several issues with this so doing a clean install now.

Biggestproblem is the missing languages now.

Other issue is the missing network around all time, no call, no internet - Not firmware related.

And it’s still “[Firmware released] charm blue note Flyme 4.5.4 Trial Version Firmware” not Stable

Is there any English-language ?

Is this really a stable version, as on it is listed as experience edition. Follow the link

4.5.X is stable for MX4 only. Both are public betas.

French, Spanish, Portuguese, English, German, Chinese supported in 4.5.4A

The title is wrong and misinforms other people.

It’s not stable and not final, with some bugs.
So, totally not recommended.

Install more locale 2. Can little help us.

@AOKP Hope the next will remain stable too :)

hello, no other news concerning this version ?

any one knows how to downgrade back to kitkat after flashing this ?

Download the kitkat update file and install it the same way you installed 4.5.4A

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