How to downgrade meizu MX3 ?

hello everybody. i have Meizu MX3 M351 used fimware OS 4.5.7.1A. now i want downgrade to Fimware 3.7.3. how i do it ?

Thanks everybody and sorry for bad english :grinning:

First of all, I think that flume 3.8.3A is a better one. I have this right now. Download it and then install it with clear data. Also I would recommend you to do the installation twice or even three times with clear data checked. Then find somewhere here the google installer 1.3 to install the Google Play services. You can find it @ the F. A. Q section I think. Good luck

@avadon thank you very much,I did it
