I just received tablet teclast X5 pro but I have a problem. I updated windows 10 and firmware (firmware 302) but after restart the screen is black. I thing windows is start but i can’t see anything.
Do you have processus for restart the tablet please or another solution ?
I’d first suggest hooking it to an external monitor to see if you get anything there.
If not, try resetting the BIOS the long way (just drain the battery completely with an external USB device). More info here: https://techtablets.com/forum/topic/how-to-reset-the-bios-with-the-screen/
