1st - You have to get root access with kingroot... (1 minute)
2nd - You have to install Flashify (1 minute)
3rd - You have to flash my TWRP for LEM5 (via Flashify) (1 minute)
4th - You have to restart LEM5 in reovery mode and do a backup (2 minute)
Et voilà! Le jeux sont fait! TOT. (5 minute)
PS (Remember this): My TWRP for LEM5 works properly, but the screen is upside down, due to a little problem for which i’m at work to resolve it. But only screen is flipped, not touch screen ok? You have to touch normal, like normal screen ok? I hope to resolve this in short time.
