There is a Chuwi Hi10 tab with 20150009xx serial number. I did not know which Bios was originally. I bought it for sale, android can not be installed because the dnx fastboot does not work. In vain, in the Bios, dnxfastboot will be displayed at a glance and disappears. I tried the EFI shell, but it starts flash, but after the system flash, it starts again and then nothing. You can not switch to fastboot and you can not crawl the installation. I would like to ask where I can find a suitable bios. I tried every bios on the side of the Chuwi forum. It works with a single bios that is 0001 to 11000. But let Android install it.
And for this serial number, no android.
Someone can help, thank you.
