820-00244 refuses to power on

"No I have the board with other computers and stuff."
Not sure what this means.
I just asked if you are testing the board on the desk, without any cable connected; apart of USB-C/power flex.

You've said to have another chip; just write correct BIOS on it.

ive tested a 00045 bios chip, now i have to write new data on 00045 bios chip but with 00244 data.

Thank you so so much. Now I just change SN and write it on chip?

 

[2informaticos]

Use it as is first.
Just see if works.

I would like to I write whatever is needed before trying to avoid doing this again lol:

Please tell me what is needed besides the SN

 

[iMuhtaseb]

I tried to program the chip and verify failed :/

 

[iMuhtaseb]

Success.

If you change serial number, then need to fix Fsys checksum.
