Hello,



I looked at all the topics with this problem but never the solution appeared....
So i bought the PRO 7 about 1 year ago for my girlfriend and now i want to upgrade it because of severals bugs and incompatibility. But
-the upgrade system in parameters dosn't work
-the upgrade in recovery mode dosn't work too "file corrupt"

my actual version is Flyme 6.3.0.0A (in french), my phone is not rooted (according to root checker)

i'm totally blocked i don't know how to fix it -_-...

Could you help me please ?
