Help with bricked chuwi vi8 plus

About a year ago after a successful windows 10 update my chuwi refused to boot, even the led did not light during charging, I thought it was the battery but I checked it with a voltmeter and it was charged.
I read somewhere that the bios might get corrupt during windows update.
I am asking two questions that require the original bios.
I got a CH341A programmer with 1.8v adapter from aliexpress, can I get the original bios to compare with what is currently on the chip.
Can anybody suggest what else might cause an issue because the tablet was running good untill the reboot after that I got nothing.
My Chuwi serial number is VI8P32G22151206935
I did send an email to aftersale@chuwi.com requesting the bios
