    Doesn't turn on after upgrading to hyperOS

    I'm not sure I understand your question When I first put the IMEI code I got the model. After that, I tried to put the serial number as well and I got the error: "Your IMEI or S/N doesn't exist, please verify and enter again"

    Doesn't turn on after upgrading to hyperOS

    Is it possible to speed up the draining of the battery so that I would try to charge it from 0? Or maybe it's not worth trying at all?

    Unfortunately, it doesn't respond at all. I tried to enter fastboot and also long press on the power button for 30 sec.

    Doesn't turn on after upgrading to hyperOS

    Hi guys, I bought a new xiaomi phone yesterday. I upgraded its firmware to hyperOS. I used it for about 2 hours and left it charging overnight. In the morning I realized that it turned off and now it won't turn on anymore. What would you suggest to do? Do you think its a hardware issue?
