Serial number: Q64G45170402747 I bought it on Aliexpress Bought it at about 2017-2018 year. Everything was working until I tried to update bios with some kind of file (launched directly on windows without any usb, etc.), tablet restarted without any main screen sign (only external hdmi worked). Tried to reprogram bios using those cheap programmers without any luck. Now, after few years, even the battery seems don’t want to charge properly (jumping at 3.124-26 V). ---
