Hi,
I previously installed Flyme 5.1.8. but it is only Chinese ans Englidh but i'd want it in French.
So  i am trying to install 5.1.6G but now, i get the "Firmware corrupt" message when i want to do it.
I try to download several time (even downloading to my PC then transfer on device) but no success.
Does somebody got the same problem and know how to solve that ?
Thnak you
