I uptaded the rom with twrp. As it ended, I went on "boot phone" but it simply turned off and didn't boot. I tried every button combination but it is not working. Thought it was the battery so i charged a few hours but nothing changes.
can you boot into twrp (power + volume up) ? or fastboot? (power + volume down), fastboot should go i think, and then via xiaomitool or adb (need PC) flashing a twrp jason and then flash a correct ROM
