If youve ordered the Black PCB version it might have 5V on the data lines,there`s a 3.3V mod you can do,it will

make the programmer a bit more stable, there`s a link to a mod in this thread

https://www.badcaps.net/forum/showpo...50&postcount=5 .Also in that post there`s some recommended

alternative CH341A software.

Here`s a good CH341A programming guide https://www.win-raid.com/t4175f16-GU...rogrammer.html Click on the +Spoiler to see the pictures.

Make 2 backups and compare them with a hex editors File-Compare function or some other method such as making a checksum and seeing if they match.

If you want to have a go at repairing the bios yourself here`s 2 guides,they don`t cover copying the DMI though so if you post your backup (along with a picture of the white/green sticker on the motherboard,with the barcode on it) someone will fix it for you
