Hi @Management, yes, they sent me, but the problem is that is not working, I did the the correct steps from the post of @manonegra222 “How update Bios for Chuwi Aerobook” but I still in the BIOS v 3.0.2 because is not flashing, maybe something is missing in the files, I don’t now, but together we can find a solution to update, lets see
I attach you a screenshot of the powershell screen that appears once i start from the usb key
And what files are in the .rar file
Thank you!!
