Hi all, today my UMI Super suddenly powered off and I can't make it turn on again. Battery was 80%+ and 2-3 apps were open in background (wasn't using it at the time). I tried connecting it to a charger or to the PC but nothing happened. I tried holding down the power button + volume down button and for 2-3 seconds the UMI logo appeared and the windows "USB connected" sound came on and after 1 second the screen turned off and the "USB disconnected" sound came on and a USB error notification appeared (device not recognized). Tried it many times and in 3 out of 10 tries I get this on and off, while at the rest tries... nothing. It seems like a software failure/corruption, is there anything I can do? I did no custom ROM flashes or mods and I'm running the latest firmware.
