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/

Replying for others that may find this later.  This is the correct solution if anyone ever messes up the BIOS and it won’t boot.  Basically drain the battery by charging a phone or something with it via the USB port.  ALL. THE. WAY. and then give it a few presses of the power button to be sure it’s completely drained, then plug it in and wait 10-15 mins while it gets some initial charge.  Then hold down the power button for 8-10 seconds and it should boot up like nothing ever happened.

Basically resets the CMOS to defaults (BIOS defaults).

So has anyone been able to successfully flash the BIOS and OS firmware to get this tablet to take both?  I’m hoping to get USB-C charging working (I have a PD charger and correct cable) and it the only part I can’t get done is the OS firmware.  I just get a yellow bang next to Teclast system firmware 3.10 and it keeps trying to update it when the system reboots but never does (always the yellow bang).  Eventually it goes back to version 302.

I’ve tried the power off for 45 minutes trick, etc. to no avail.  It took the BIOS flash just fine, but the OS firmware it isn’t taking.  Windows just says “updating your system” or something in white letters for a split second under the blue windows logo immediately after POST and that’s all.  It never actually goes through the process shown in the PDF of the firmware update.

That being said, if anyone would like me to paypal them a 5 or 10 spot for help getting this going I’m just looking to get this one last thing done before I start customizing the X5 Pro.  If you have the solution please share it.
