@Akkash1105 您好，我的手机是红米note2开发版，现在用系统的root 权限, SuperSU文件被占，我不会用电脑刷，现在该怎么处理，请您帮助到我。谢谢您！
@Zouxia Hi bro, sorry I don't speak Chinese, let me ask my good friend to answer your question. May take a little while, check back tonight
@Zouxia Hi zouxia, here is the text copy-pasted by a friend:
这个情况除了用电脑线刷以外没有别的办法。红米开发版应该很容易解锁，上网下载ADB工具并刷入TWRP, 在TWRP里sideload SuperSU.
My friend also mentioned a name, 尘封之泪, says if you need help you can look for him. But he didn't send me any links, wat a jerk.
@Zouxia No problem man, always a pleasure
@Akkash1105 Hi, have u heard An App called SuperSU It is used for installing more ROMs on one device.After a lineage OS was installed on my Xiaomi Mi 6(sagit) as secondary system, I tried to root my secondary system as the post said how to patch a .zip and flash it in rec mode or in APP. But unfortunately SuperSU told me that I haven't root my device when first launch it. What should I do to solve this problem?

@Akkash1105 hi ,bro ,I have the same problem as he ,my device is xiaomi redmi note 4x with Android 8.1 , I flashed super su by twrp , success, but I cannot find the supersu app was installed after reboot, and I installed it from app store (coolapk), launched it and it
tips"the su binary needs to be updated!", I updated it and succeed, without reboot I tried "install su into system/", and it keep in instilling more than 5 minutes, I stopped the app and rebooted my device.
Now it prompts me "su binary occurred" when launched it . Should I reflash the supersu.zip with twrp? Or what should I do?
