    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!!! :)

    Hi,
    Thanks for the link

    I flashed the Latest Global Developer version of your link. The backlight is working and I can use my Mi4 though Mi PC Suite
    But the screen is still not working
    Is it possible to check the hardware?

    Oh you already reflashed it, didn't check the link in first post.



    Check this video and display cable locations, maybe open them little bit and close again to see if it is just a contact problem.

    I check everything like in the video and it didn't works yet. I try also to install the Cyanogenmod Recovery but no difference...
    It was the last chance or do you an other idea?
    I should maybe change all the screen?

    Sounds like broken display to me, but i have very little knowledge about fixing hardware.
