It worked on my SQ-40E86H.
My phone was at the repair shop,and they updated the firmware from R04 to R08.
Google Chrome wasnt force closing anymore(verified with 3 Quadro SQ-50E85F)
There was a new category in settings,dedicated to the proximity sensor(swipe homescreen pages with waving,etc.)
Framaroot was rendered useless(probably because they "covered the security hole" which let us root it before the R08)
After 3 days and testing of over 12 root tools,i finally managed to find GeniusRoot
.It didnt use SuperUser nor SuperSU,it uses KingUser instead.KingUser works the same way as Chainfires Superuser applications,but has a better UI :P
