Hello! I have a LTE Mi4 and I installed supersu to manage the root. But I did a mistake by updating the binary, I choose restart with twrp recovery. Then I had like a boot loop. I fixed it using this thread: http://en.miui.com/thread-59891-1-1.html but now the display is not working anymore. The touch pad is working and I can controll miui but I can't see nothing on the screen (no miui logo on boot). But I have the control of the phone with MiPhoneManager and the option screencast. Do you have an idea if it is a software mistake and how I can fix it or if I have to change completely the display? Thanks a lot!!!
