Are you upset about the boot issue that’s caused by corrupted BIOS on your board? Since the board doesn’t boot, we can not use the U disk to reflash BIOS. At this point we need to use the BIOS programmer to do it.
Let's get started!

What we need:
1.BIOS programmer
2.BIOS file
(Please download the right file according to your product model)

Suitable models:
Alpha 800, Alpha 800s, Alpha 864, Alpha 864s, Delta

Unlike LattePanda V1.0, LattePanda Alpha and Delta have 8pins on GPIO for BIOS. It would be easier for us to flash Bios. 1.jpg 1.jpg (98.68 KiB) Viewed 27274 times 1.Connect your programmer to LattePanda. Please be sure you connect it the right way round.
(As you can see, I powered the Alpha. It seems there is no much difference between plugged in and unplugged) 2.jpg 2.jpg (100.73 KiB) Viewed 27274 times 3.jpg 3.jpg (44.33 KiB) Viewed 27274 times

2.Now, just plug your programmer in to a USB port on your PC and open the software of the bios programmer.
First please select right BIOS chip model.
Alpha: Winbond W25Q64 (what I use here)
Delta: GigaDevice GD25LQ64

4.After program and verify, remove the clip.
Plug into the power and wait few seconds, you can see the red LED goes steady and Blue light blinks as normal if you succeed. Then hold the power button, you LP is reborn.

Good luck to everyone!
