Which methods have you tried? There are 8 auto root tools in the rooting tools forum. And the last option is to build cwm and root from recovery.
Please tell us what tools you've tried and where you had problems so its easier to troubleshoot.
I have tried Kingo root, vroot, framaroot, rootgenius, kingroot, srs root, monochoper auto root.
After that I checked with Root Checker, it said no root. Update supersu always failed.
Also I can not go to original recovery mode by click power+volume up any more.
When i tried to press power+volume down, my phone booted in to a chinese menu which i don'n unterstand. That happen after i use vroot_iroot apk on my phone.
There is a "Kingroot" on my phone also, but my phone still can not acess apllications which need root permission like titanium backup or root explorer.
Please help.
This is what i got by power+volume down. Is this a recovery? My phone still not rooted and no way to update supersu
