    Q1572878639080 , May 16, 2020 :
    Hi, I have a broken phone after updating over the air. I'm trying to restore my phone using "6 T_MsmDownloadTool_v4.0.59_OS_v9.0.13", but I keep getting the error "firehose getufsinfo failed" after 21 seconds every time. I read that I need to make sure that the phone is turned off before repare, but I have a completely black screen! I only hear the sound when connected to a computer with all the volume buttons clamped down. What should I do?

    try to connect to the rear ports of your pc. Restart your pc and try again.

    The same thing happened to me and that's how I solved it.

    Check that the drivers are correctly installed

    regards.
