Music glitch bug - please help !

hi friends..
I updated my M3 to T2.004.6 ..now when my M3 plays any audio file, the last 1 second of that file is repeated after the file is played completely.. this is so annoying.. there is a glitch after every music played..
Meizu stopped updating the firmware of M3 with this bug on T2.004.6..!
I posted for help in Meizu Forum, instead of helping me they deleted my post !
Any way to downgrade the firmware? or any tips to overcome this bug..?

please help me..

You can easily downgrade if you want too, at least for M6 it is. Just remember backup your files.

I tired to downgrade , but it isn't downgrading..
I copied M3.EBN and Resource files of old version (T2.003.4) to the root and then when I restart it, the firmware upgrading screen appears.. but then after that the screen goes white and shuts down.. then I recopied the Resource file and restarted again .. still white screen...!

Any help? any other links of the basic firmware..?
because when i bought M3, this music bug was not there.. it got in after firmware upgrade..
