I was following my process for updating the bios for auto power on and didn't realize the "Newer" LattePanda Alphas that I was working with were the KR310. I accidentally flashed the KR300 auto power on bios onto them and ran the efuit.efi command with the KR300 bin files.
I have tried overwriting the bios directly to the chip using a CH341 programmer. I pass write/verify and a visual spot check looks like everything is correct but the Panda won't boot.
Is it possible the bios file on Github is incorrect or have I done something to the EC Rom that I cannot fix?
Any help is greatly appreciated.
Hello, if you updated a wrong EC file, it can not be fixed by this tutorial. pls contact techsupport@lattepanda.com for help.
Enjoy Tinkering with LattePanda ! :lol:

With an CH341 programmer you can work on the BIOS, but not on EC ROM (second step of update process with command "eFuitX64.efi /u XXXX.bin"). If the EC ROM is corrupted then you cannot do anything else or your side, you need to contact LP support with an detailed explanation of the steps you followed and status. They may proposed you to send the LP back in the factory in China to overwrite EC ROM.
